A careful attitude to your health and knowledge of the characteristics of your body is the key to well-being and longevity. This is especially true for women who are faced with many gynecological problems. Every month in their body there are cyclical changes that affect its work.
They are under the control of hormones, many of which are able to influence, including the center of thermoregulation. A better understanding of cyclic changes in the body and measuring the rectal temperature will help to suspect pathology in time. This method is based on the fact that estrogen reduces it, and progesterone - increases it.
Therefore, in the first phase, the temperature is normally low, up to 36.6, and after ovulation, it jumps above 37. This should be the case in the cycle in which the egg matured.
Rectal temperature before menstruation is slightly reduced. Usually this period lasts about 3 days. This is due to the fact that the level of progesterone decreases as a result of a decrease in the functioning of the corpus luteum.
When the temperature before menstruation is above 37, then there is a chance of pregnancy. In this case, it can even increase to 37.4 due to the greater production of progesterone by the corpus luteum. This process is stimulated by hCG, which begins to be released after implantation by the chorion of the embryo.
However, sometimes the temperature before menstruation indicates an inflammatory process. Especially if the numbers exceed 37.6. During this period, immunity decreases slightly and chronic diseases, especially inflammation of the appendages , often worsen .
The reliability of the method of measuring rectal temperature depends on compliance with all the rules. More often it is called basal, as it is fixed in a state of complete rest. Measurement is carried out daily in the morning, choosing a constant time. The thermometer can be used both mercury and electronic.
The disadvantage of this method is its high sensitivity to various factors. These include taking alcohol, drugs, sex, exercise, stress the day before. They should be avoided or marked as much as possible.
Measurement is carried out right in bed after waking up. Before this, you can not get up, sit down, it is undesirable to even talk and open your eyes. Therefore, the thermometer must be prepared the day before so that you do not have to shake it or stand behind it.
The measurement time can be changed within half an hour. Otherwise, the indication may be unreliable. If you had to get into the toilet a few hours before the selected time, then this should be noted.
Many women are familiar with the phenomenon of PMS firsthand. Low-grade fever before menstruation is one of its symptoms. Among them, there is also chest pain, irritability. Elevated temperature is also observed during pregnancy, this is due to total hormonal changes in the body.
In general, the temperature before menstruation is very individual. However, if it has changed and is not as usual, then only an experienced doctor will be able to distinguish between the norm and pathology. After all, an increased temperature before menstruation can be with endometriosis, cysts, and even diseases that are not related to gynecology.
The period before menstruation, as well as they themselves are a very favorable time for the development of acute inflammation of the uterus, as well as its appendages. Indeed, at this time, a small opening of the cervical canal occurs, and the infection from the vagina penetrates these organs more easily. In acute endometritis and salpingo-oophoritis, the thermometer can show high values.
So, the temperature before menstruation should be at 37 degrees or slightly lower. A higher value may indicate a pregnancy or inflammation. Body temperature can also be slightly increased - this is a variant of the norm. If it is very high, then this is most likely a sign of the disease.
