Can a pregnant woman have 36.6. Low basal temperature during pregnancy

Basal temperature value at initial stages pregnancy is of great diagnostic value. Measuring this indicator is especially important for those women who previously faced the problem of miscarriage or missed pregnancy, or at the moment their pregnancy is at risk.

After the expiration, the basal temperature indicator loses its value.

Fine basal temperature during pregnancy it should be 37.1-37.3º, sometimes it can rise to 38, but no more. Therefore, the basal temperature during pregnancy is 36, 36.6 and up to 36.9 is not an indicator of the norm and should alert the woman.

A decrease in basal temperature during pregnancy may indicate a risk of termination of pregnancy. If the basal temperature during pregnancy suddenly dropped, then in this case it is necessary to go for a consultation with a doctor, especially if the decrease in the basal temperature during pregnancy is accompanied by pain, persistent or bloody discharge.

Reasons for a decrease in basal temperature

Basal temperature in a pregnant woman decreases if the body reduces the production of the hormone progesterone. A blood test is needed to determine if hormones are actually causing the temperature drop. When the diagnosis is confirmed, the woman is prescribed appropriate medications containing progesterone.

A decrease in basal temperature is not clear sign that the woman will have a miscarriage. A low basal temperature during pregnancy only indirectly indicates the possibility of abortion. The onset of miscarriage is indicated only by bleeding and an increase in basal temperature values.

Pregnancy can also occur at a low basal temperature. If a woman is feeling well, the fetus is developing normally, then you should not worry about low basal temperature values. Perhaps this is just an individual feature of the organism.

The menstrual cycle is divided into phases, successively replacing each other. Depending on the phase, the content of hormones in a woman's body can either increase or decrease, along with this, the basal temperature indicators also change.

Basal temperature values

The body of every person possesses individual characteristics... Therefore, each woman's normal basal temperature is different. In this case, the main criterion is not the temperature indicator, but the difference in temperature values between the phases of the cycle.

If the female body is functioning normally, the minimum difference between the temperatures in the first and second phases is at least 0.4 degrees.

In a normal state, in the follicular phase (immediately after menstruation), the level of estrogen in the blood rises, as a result of which a basal temperature of 36.7 degrees is determined. In some situations, the values may be slightly lower, for example, the basal temperature of 36.4 degrees in the follicular phase is not a violation. However, if during this period the basal temperature is 36.1 degrees, this is already a pathology that requires consultation with a specialist.

Before the onset of ovulation, the basal temperature is 36.6 degrees. What does a basal temperature of 36.8 mean during this period? Basal temperature of 36.8 at this stage of the cycle is also a normal indicator. On the day of egg maturation, temperature values increase, and a basal temperature of 36.9 is determined.

What does it mean? This suggests that the level of hormones has increased, and the body is ready for fertilization and the fixation of the ovum in the wall of the uterus. At the time of ovulation, temperature indicators can reach 37.2 degrees. After ovulation, the basal temperature is 36.9 degrees.

Then a decrease in temperature values is observed. But here, too, everything is individual - some women have a basal temperature in the second phase of 36.8 degrees, while others have a basal temperature of 36.9 in the second phase. Sometimes immediately before menstruation, the basal temperature is 36.9 degrees - this also does not go beyond the normal range.

However, in some cases, a basal temperature of 36.9 degrees before the onset of menstruation can talk about pathology, so a consultation with a gynecologist will not be superfluous.

Low basal temperature

As noted above, the basal temperature is a purely individual indicator and there is no strict standard. So, for example, a basal temperature of 36 degrees and a basal temperature of 36.5 degrees is a normal individual phenomenon, provided that the difference between the phases is at least 0.4 degrees.

If the difference in temperature values is less than 0.4 degrees or the average basal temperature is at a low level, this may indicate a violation.

For example, low temperature indicators are observed with such pathologies:

Basal temperature data during pregnancy

During pregnancy, basal temperature is the most important indicator by which you can identify possible violations at an early stage, up to the threat of miscarriage. Temperature indicators are of particular importance when menstruation is delayed.

A basal temperature of 36.7 with a delay, as a rule, means that conception has not occurred. The reason for the absence of menstruation in this case may be a gynecological disorder. A symptom of a violation may be a basal temperature of 36.8 with a delay.

However, the cause of the delay is not always pathology. A shift in the menstrual cycle can be associated, for example, with a change in climate. Therefore, all factors must be taken into account when plotting temperature values.

If conception has occurred, the temperature indicators will be 37 degrees or more. In a normal state, a basal temperature of 36.7 cannot be during pregnancy. During the carrying of a child, the content of progesterone is increased, which means that the temperature indicators are also increased. However, in certain situations, the temperature may be colder.

It should be noted that it is precisely a persistent decrease in temperature values that is meant. If a basal temperature of 36.8 during pregnancy was detected once, this is not yet a symptom of a disorder. A similar phenomenon rather speaks of the general state of the woman's body.

The expectant mother should be alerted to the low temperature values that have been determined for some time. Basal temperature 36.6 during pregnancy, in most cases, indicates a threat of miscarriage.

In such a situation, it is necessary to immediately contact a medical institution, especially if low temperature readings are accompanied by symptoms such as pain, persistent uterine tone, spotting.

Basal temperature of 36.9 during pregnancy may be associated with a deficiency of sex hormones. Decreased production of progesterone in the body future mother can lead to miscarriage.

After all, it is progesterone that prevents uterine contractions and, as a result, detachment of the ovum.

To establish an accurate diagnosis, a blood test is mandatory. If the reason for the decrease in temperature indicators is a deficiency of progesterone, the expectant mother is prescribed special medications containing progesterone.

With the timely detection of deviations and appropriate medical manipulations, pregnancy can be saved in most cases.

In order to obtain accurate data, the temperature must be measured taking into account the following recommendations:

When should you see a specialist?

If, under the condition of correct measurements of temperature indicators, significant deviations from the norm are observed for a long time, you should consult a gynecologist for an additional medical examination and a correct diagnosis.

A specialist consultation is necessary in such situations:

Basal temperature control is an effective diagnostic method when planning a pregnancy.

Also, graphs of temperature indicators allow you to identify hormonal disorders in a woman's body (provided that the temperature is measured correctly). Therefore, many specialists today use this simple, but at the same time reliable way research.

Basal temperature during pregnancy is measured by many women. What is this parameter and what can be learned from these measurements?

This "type" of temperature, if you can call it that, is one of the classic, oldest methods for determining ovulation and hormonal imbalance in women. That is, measurements are usually carried out by women planning a child, who want to speed up the onset of conception, to predict the most favorable days for this. If there is no ovulation on the BT schedule for several months in a row, this is a reason for a gynecological and, possibly, endocrinological examination.

Since the basal temperature during pregnancy before the delay usually rises to 37 and above degrees, on the basis of this, one can suspect an interesting situation in oneself even when it is too early to do the tests. Approximately 3-5 days for the estimated start of the delay. On the other hand, it will be much more effective for this purpose to pass a blood test for hCG. HCG begins to be produced after the implantation of a fertilized egg. That is, about 7-10 days after intercourse.

But back to the BT level. The basal temperature during pregnancy is considered to be 37.0, 37.1 degrees. This increase occurs due to the effect of the hormone progesterone - the main one responsible for the preservation and development of the embryo. With a lack of this hormone, there are threats of miscarriage or spontaneous interruption. That is why the basal temperature during pregnancy of 36.6, 36.7, 36.8, 36.9 degrees makes many people panic, since it would be logical to assume that not everything is in order.

What do doctors say about this? Soviet-trained doctors, of whom many still work in Russian antenatal clinics and hospitals, advise their patients (expectant mothers) to measure BT if they have had miscarriages before or if there are any reasons to suspect a pathology (for example, hCG growth is below normal).

Modern doctors are of the opinion that basal temperature at the onset of pregnancy cannot say anything. There are categories of women who have a high risk of miscarriage, but special control is exercised over such women. This control consists in carrying out transvaginal ultrasound examinations and monitoring the dynamics of hCG growth. And BT is not informative, since there is a huge probability of errors, its accuracy depends on too many factors. In a word, it is better not to search the Internet for "basal temperature during pregnancy, the schedule is normal", but to listen more carefully to the tangible signals of your body and be sure to follow all the recommendations of your doctor.

If the thought of finding out your BT does not leave you, then be sure to follow the rules that will help to minimize measurement errors. So, measurements are taken exclusively after a night's sleep and before getting out of bed, rectally. The thermometer can be used both mercury and electronic. But the second has more possible errors. Basal temperature during pregnancy in the evening is not informative, since after physical activity it tends to increase. And don't forget about the factors that can also affect the result. These are various diseases, the symptom of which is fever, sexual intercourse, intense excitement, etc.

A pregnant woman is more worried about her health than anyone else. In case of any deviations from the norm, the woman begins to panic. She is especially worried about body temperature. The norm is 36.6 degrees. We can talk about deviations if the thermometer shows above 37 degrees and below 36 degrees. When does the temperature drop during pregnancy? How dangerous is it? How to raise a low temperature?

Features of temperature during pregnancy

It is known that every woman can have her own temperature rate. It ranges from 36 to 37.2 degrees. Medical observations show that healthy person Temperatures are low in the morning and may rise during the day.

Typically, the temperature rises:

After drinking hot.
After eating.
After taking a bath.
After experiencing stress.
After a hot bath.
After being in a stuffy room.

Temperature measurement rules for pregnant women

You should understand that changes in indicators may be associated with an incorrect measurement of body temperature:

Dry the thermometer with a dry towel.
Take it easy.
An electronic thermometer measures the temperature for no more than 5 minutes.
With a mercury thermometer, the temperature should be measured no more than 10 minutes.
Do not drink hot drinks before taking the temperature.

Temperature can be measured in several ways:

In the rectum.
Armpits.
In the mouth.

In the rectum and in the mouth, the indicators are always higher. If a woman does not even think about her temperature, she takes a thermometer when she shivers, then during pregnancy she constantly measures her body temperature.

Causes of low temperature in pregnant women

Doctors warn: during pregnancy, the temperature may rise slightly, but low temperature is very dangerous. Such a symptom quite often indicates a specific pathology. Most often, a disease of the endocrine system is. In this case, the pregnant woman:

Sleepy.
Weak.
Tired.

Puffiness also increases significantly. Do not let the problem go by itself. Contact an endocrinologist immediately if your temperature is below 36 degrees. You may additionally need to visit a therapist.

Hypothermia refers to a pathological and rather dangerous condition. It is diagnosed when the temperature of 36 degrees lasts for about two days. Hypothermia can be triggered by a cold, toxicosis, ARVI, weak the immune system, depletion of the central nervous system.

The following main reasons for the low temperature can be distinguished:

. When the hemoglobin level drops, the temperature drops.
Malnutrition. As a rule, after a woman eats, her temperature will return to normal.
Different loads - physical, mental negatively affects the woman's body, so her temperature drops.
Hypoglycemia leads to low temperature readings. The pregnant woman develops severe weakness, her head begins to spin. In some situations, nausea, vomiting are troubling, while the skin is very pale. This condition occurs in the case of inappropriate nutrition, starvation, and sometimes is the first sign of diabetes mellitus.

To find out why the temperature is dropping, it is important to undergo an examination. The problem can be caused by very dangerous reasons. After finding out the reason, the doctor will give recommendations on how to normalize the temperature:

Eat well.
Reduce loads.
Review your daily routine.
Take vitamins.
Avoid stress.
Take iron supplements.

In case of hypoglycemia and thyroid diseases, it is necessary to undergo additional examination by an endocrinologist.

Low basal temperature in pregnant women

Basal temperature indicators are of no small importance. Low rates are dangerous early in pregnancy. They can alert you to the danger of termination of pregnancy. In the first weeks, the indicator should be around 37 or 37.5 degrees. He points out that a woman has enough progesterone in her body and the pregnancy develops normally. Do not panic if the temperature is below 37 degrees, but your tests and health are normal. Basal temperature is not so important, the doctor pays attention to:

Analyzes of the woman.
Ultrasound.
Other signs of pregnancy.

A high basal temperature does not guarantee a normal pregnancy. Other factors must be taken into account.

It should be borne in mind that each organism is individual. In some pregnant women, the temperature may rise, while in others it may not. The main thing is that the indicator should not be lower than 36.5.

Basal temperature may decrease:

For colds.
In case of overwork.
With severe toxicosis.

Low basal temperature is dangerous if it is accompanied by other ailments. In this case, the pregnant woman is prescribed hormone therapy:, Dyufostan.

Attention! If you have a low basal temperature, go to your doctor right away, it may indicate a lack of progesterone. Typically, problems with this hormone occur when ectopic pregnancy, the threat of miscarriage, frozen pregnancy, as well as with retrochorial hematoma.

Features of measuring basal temperature in pregnant women

It is necessary to use the same thermometer, more precisely, the mercury temperature will show.
It is best to take your temperature right after sleep.

If you have severe toxicosis, measure your temperature right away. When it is low, be sure to consult your doctor.

In this way, low temperature body and are not indicators of the norm. If you feel unwell and have a low temperature, be sure to go to the hospital. Sometimes a low temperature indicates serious pathology. Basal temperature is no less important. When it goes down, you should visit your gynecologist right away. This symptom may be the first signal that there is not enough progesterone in the body and you may lose your baby. Carefully monitor your health, the health of your baby depends on it!

An increased body temperature is always a cause for concern. When the thermometer mark creeps up, the expectant mother begins to seriously worry about the health of her baby. The temperature, which does not reach the norm, is no less frightening. What does this mean? Are temperature changes during pregnancy so dangerous?

Normal temperature

Maintaining a constant body temperature - necessary condition for the normal functioning of the human body. A temperature of 36.6 ° C is considered the norm. Minor deviations in any direction are allowed. Body temperature in the range from 35.8 to 36.9 ° C signals the successful course of all processes in the human body and does not require correction.

It is important to understand that everyone has their own body temperature norm. If a woman's temperature has always been recorded in the range of 36.5 - 36.7 ° C, then its increase to 36.9 ° C will be a signal of a malfunction in the body. Regular temperature measurement will allow you to track the slightest changes and notice problems that have arisen in time.

Body temperature is measured in the armpit or rectum. The latter option is more often used at the planning stage of pregnancy. By controlling the basal temperature (in the rectum), you can track hormonal changes in the body, determine ovulation or the onset of pregnancy at the earliest possible date. The parameters in the rectum will differ from the parameters in the armpit by 0.5-1 ° C.

Physiological hyperthermia

Pregnancy itself is a reason for a slight increase in body temperature. After conception, the production of progesterone, a hormone that ensures the normal course of all 40 weeks of gestation, increases. Progesterone prepares the endometrium for implantation, reduces the tone of the uterus, and also affects many links in the metabolism. At the same time, progesterone is a pyrogen - a substance that increases body temperature. The impact of the main hormone of pregnancy provokes an increase in body temperature up to 37-37.4 ° C, as well as the occurrence of hot flashes and increased sweating common to all expectant mothers.

Criteria for physiological hyperthermia:

The body temperature does not rise more than 37.5 ° C.
High body temperature lasts only up to 14 weeks.
The general condition of the woman does not deteriorate. No chills, headache, dizziness, severe weakness.
An increase in body temperature is not accompanied by catarrhal symptoms (cough, runny nose, nasal congestion), pain in the abdomen, lumbar region, joints or other parts of the body.

Physiological hyperthermia persists until the end of the first trimester. An increase in body temperature after 14 weeks is a reason to see a doctor.

Pathological hyperthermia

During pregnancy, there is a natural decrease in immunity, which provokes the development of a variety of diseases. The expectant mother is susceptible to viral infections, especially in the cold season and during epidemics of influenza and ARVI. Are becoming aggravated chronic diseases, new health problems arise. Any pathology can cause an increase in body temperature and the occurrence of other typical symptoms of general intoxication.

Probable causes of hyperthermia:

ARVI

Influenza and other respiratory infections are one of the most common causes of fever. Symptoms of the disease do not have distinctive features:

general weakness, decreased performance;
headache;
chills;
nasal congestion;
runny nose (mucous or purulent);
sneezing;
lacrimation;
sore throat;
sore throat;
cough (dry or wet).

Influenza is characterized by a significant increase in body temperature up to 39 ° C and above, the appearance of severe headaches against the background of minimal catarrhal phenomena. On the other hand, ARVI is characterized by moderate fever with severe runny nose, sneezing, and coughing. Lachrymation is noted in some viral infections, as well as in people prone to allergic reactions.

A viral infection that occurs during pregnancy poses a danger to the fetus:

High body temperature increases the tone of the uterus and significantly increases the risk of miscarriage or premature birth.
The possibility of infection of the fetus is not excluded.

The consequences for the fetus are largely determined by the gestational age. In the first trimester, an increase in body temperature against the background of a viral infection threatens spontaneous miscarriage or regression of pregnancy. Temperatures above 38 ° C are dangerous. Up to this limit, the body successfully copes with fever without significant consequences for the course of pregnancy and fetal development.

In the second half of pregnancy, the risk of miscarriage decreases, but the development of placental insufficiency... Against the background of a viral infection, the functioning of the placenta is disrupted. The delivery of oxygen and nutrients decreases, fetal hypoxia develops, and a delay in its development is noted. This condition can lead to premature birth. In childbirth at term, the likelihood of having a small baby increases.

Physiological decrease in immunity during pregnancy increases the risk of complications:

otitis media - inflammation of the middle ear;
sinusitis - damage to the sinuses of the nose;
laryngitis - inflammation of the larynx;
bronchitis - damage to the bronchi;
pneumonia is an inflammation of the lungs.

SARS during pregnancy is dangerous not only for its complications. The disease creates an additional burden on the body of the expectant mother. Against the background of a high body temperature, fainting and a significant deterioration in well-being are possible. Complications develop quite quickly, and it is not always possible to predict their occurrence in time. Treatment of influenza and ARVI, accompanied by a high body temperature, should be carried out only under the supervision of a doctor.

Diseases of the urinary system

Cystitis and pyelonephritis - common reason high fever during pregnancy. Inflammation Bladder usually makes itself felt in the early stages, while kidney pathology worsens in the third trimester (with an increase in the load on the organs of the urinary system). Difficulty in the outflow of urine due to the pressure of the uterus, an increase in the BCC and blood passing through the kidneys - all this leads to the development of pyelonephritis.

Signs of cystitis:

pain over the bosom;
soreness when urinating;
increased urination;
false urge to use the toilet.

Signs of pyelonephritis:

pain in the lumbar region, radiating to the thigh, groin;
frequent and painful urination.

All these conditions occur against a background of high body temperature and are accompanied by a significant deterioration in the woman's condition. Urinary tract infections can lead to the following complications:

abortion ahead of time (spontaneous miscarriage or premature birth);
placental insufficiency;
delayed fetal development, chronic hypoxia;
polyhydramnios.

The shorter the gestation period, the more serious the consequences for the fetus. Gestational pyelonephritis is also a provoking factor for the development of gestosis, a specific complication of pregnancy. Gestosis can cause premature birth and other equally dangerous conditions.

Sharp belly

This term is understood as damage to the abdominal organs with irritation of the peritoneum. The appearance of severe abdominal pain is noted, the localization of which will depend on the primary focus. The pain occurs against a background of high body temperature. Vomiting, nausea, diarrhea, and bloating are possible. Characteristic is the tension of the muscles of the abdominal wall, which clearly indicates a pathology in this area.

Possible reasons:

acute appendicitis;
acute cholecystitis;
acute pancreatitis;
perforated stomach or duodenal ulcer;
intestinal obstruction;
trauma;
strangulated hernia;
torsion of the ovarian cyst;
ectopic pregnancy.

Treatment of any of these pathologies is carried out only in a hospital. Emergency surgery is possible at any stage of pregnancy. Delay can cost the life of a woman and her baby.

Alarming symptoms

Special attention should be paid to situations in which heat the body is combined with the following symptoms:

violent persistent cough;
earache;
Strong headache;
photophobia, intolerance to harsh sounds;
skin rash;
joint pain;
pain in the abdomen (including over the bosom);
a sharp decrease in urine output or complete absence of urine;
incessant vomiting;
slowing down the activity of the fetus.

If any of these symptoms occur, you need to urgently consult a doctor or call an ambulance.

Temperature reduction methods

Having found out the cause of the increased body temperature, the doctor will select the optimal therapy regimen. After the restoration of body functions, the body temperature will also return to normal. Symptomatic treatment assigned only when the mark of 38.5 ° C is exceeded. It is not necessary to lower the temperature to this limit. A woman's body is able to independently cope with hyperthermia without any serious consequences.

Reception drugs during pregnancy is limited due to possible adverse effects on the fetus. With a drug lowering of the temperature, you should adhere to some rules:

During pregnancy, drugs based on paracetamol and ibuprofen (NSAIDs) are approved for use. It is forbidden to use aspirin!
All medicines can be taken only with the agreement of a doctor.
It is not recommended to drink NSAIDs in the I and III trimester.
Taking antipyretic drugs should be no more than 3 days.
Do not exceed the dosage of the drug.
The interval between taking the drug should be at least 4 hours.

At a body temperature not exceeding 39 ° C and relatively well-being you can try non-drug methods of exposure:

Rubbing the skin with cool water (alcohol cannot be used!). Evaporation of moisture from a damp body surface enhances heat transfer and lowers body temperature.
Use a large number liquids (plain water, berry fruit drinks, natural juices, compotes, weak tea) removes toxins and relieves intoxication symptoms.
Taking diaphoretic drinks (tea with mint, lemon, raspberry or raspberry jam, milk with honey, etc.).

If the high body temperature does not decrease within three days, it is imperative to see a doctor.

Hypothermia

A decrease in body temperature during pregnancy can be associated with the following conditions:

endocrine pathology;
decrease in the general tone of the body, loss of strength;
malnutrition (including strict diets);
prolonged exposure to the cold;
internal bleeding;
taking certain medications (including overdose).

A decrease in body temperature to 35.7 ° C and below indicates serious malfunctions in the body. In this condition, you must consult a doctor.

The decrease in basal temperature in pregnant women deserves special attention. Normally, after conceiving a child, the temperature rises and remains within 37 ° C until the end of the first trimester. A decrease in basal temperature earlier than this period may be a sign of one of the following conditions:
