Why are the periods?

In our time, the fact that women and girls go through periods is not a secret to anyone. Menstruation, or menstruation, is a natural biological process that is a sign that the girl's body has reached puberty and is ready for pregnancy.

Let's take a closer look at why menstruations are coming.

Monthly: what is it and how do they arise?

Approximately once a month, a thickening of the inner layer of the uterus occurs in the woman’s body. This is necessary in order to take the fertilized egg and subsequently carry the child. But if the pregnancy does not occur, then the inner layer (endometrium) exfoliates and leaves the uterus with blood. This process of bleeding and called monthly.

The beginning of the first menstruation usually occurs at the age of 12-16 years, although it happens that this happens later. It is believed that the healthier the body, the earlier the menstruation begins.

After the first menstruation, the second may begin several months later.This should not be frightened - over time, the cycle will be established and will be equal to about 28 days (maybe a little more or a little less), that is, so many days will pass from the first day of one month to the first day of the next.

Months themselves last on average from 2 to 7 days, and this is considered the norm. If the monthly go more than a week, very painful and abundant, it is worth to consult a doctor, perhaps there are some violations. Small bleeding in between periods is also a reason to be wary and consult a gynecologist.

Symptoms of menstruation

Many women feel the approach of menstruation. This phenomenon is called premenstrual syndrome (PMS). Premenstrual syndrome is manifested a few days before the onset of menstruation and is expressed in increased emotionality, vulnerability, depressive moods, tearfulness. Also, a woman may feel very tired and uncomfortable in the back and in the lower abdomen.

Periods themselves are also often accompanied by unpleasant symptoms. There may be back pain, fever, unpleasant "sipping" and even spasms in the lower abdomen.The breast slightly increases in size, swells.

Doctors do not recommend having sex during menstruation. This is unhygienic and significantly increases the risk of infection. In addition, the mere fact of the onset of menstruation does not mean that it is impossible to get pregnant at this time - this possibility remains.

Stress, unregulated physical exertion, the use of potent drugs, including birth control pills, can have a big impact on the menstrual cycle.

Also, menstruation is terminated during pregnancy and ends naturally at about 50 years of age, when a woman begins menopause.
