What can tell the temperature before menstruation
What is the essence of basal temperature measurement? Gynecologists claim that its height is determined by the phase of the cycle of a woman. That is, the temperature before the month will vary depending on what day you measure it. Physiologically, this is understandable: the sex hormone progesterone in a certain way affects the center of thermoregulation, which is located in the hypothalamus. Since on different days of the female cycle, the concentration of this hormone in the body varies, respectively, with it, the basal temperature will be characterized by different indicators.
Diseases and Conditions
So, who may need to measure, what is the temperature before menstruation? First of all, women who have long and unsuccessfully trying to conceive a child. Such measurements help to determine the most favorable days of conception. Secondly, basal temperature measurement is successfully used as a method of contraception.Thirdly, its fluctuations make it possible to detect the presence of hormonal disorders and inflammatory processes occurring in the organs of the small pelvis. Finally, it is often measured during so-called “delays”.
What should be the norm?
A normal temperature before menstruation in a completely healthy woman goes through several stages. During the first phase (doctors call it the term “follicular”), indicators, as a rule, do not exceed 37 degrees. On average, it ranges between 36.4 and 36.7. Immediately before the onset of ovulation, the temperature drops slightly, and then jumps sharply by 0.5 degrees. The thermometer will hold this mark throughout the second, or as it is called the lutein, phase of the cycle. The temperature before menstruation becomes slightly lower. During critical days, it is usually around 37 degrees. Having carried out simple calculations, it can be summarized that the basal temperature in the luteal phase of a woman whose health is in perfect order is 37.2–37.4 degrees.
However, whatever the subfebrile temperature is before menstruation, attention should be paid to the difference in performance between the first and second phases. Normally, it will be about 0.4 degrees.
Possible causes of deviations from the norm
All deviations from the above standards may be due to a number of reasons. Among the most common, gynecologists refer to diseases such as endometritis and inflammation of the appendages. In addition, the cause may be a lack of progesterone in the body. In some cases, changes in temperature indicate the occurrence of pregnancy. The last version needs to be discussed in more detail.
The basal and rectal temperature before menstruation indicates that a woman is pregnant only when their indicators do not decline before the onset of menstruation and exceed 37 degrees.
