Does 'menstruation' come late? Doctor: In addition to pregnancy, it is mostly related to these 4 reasons!

After girls enter puberty, not only will their height grow rapidly, but their secondary sexual characteristics will also begin to develop. Moreover, in the age group of 12-16, women often have their first "menarche", that is, their first menstruation, which is the primary feature of the ovaries beginning to develop and gradually becoming ovulatory.

　　Usually, about half a year to a year after menarche, women often have irregular menstrual cramps, and sometimes they will have second cramps every few months, half a year, or even a year. This is a normal physiological manifestation .

　　As women's bodies continue to develop and their ovarian functions become more mature, menstrual cramps will gradually become regular. So here comes the question, the tide was very punctual before, but this time it was delayed, what is going on?

　　If women's menstruation is delayed, the first thing to consider is whether it is early pregnancy . You must know that the reason why the endometrium undergoes periodic metabolism is that it will change with ovarian ovulation and endocrine. When the ovary releases an egg, the lining of the uterus thickens in order for the fertilized egg to implant and develop .

　　However, the endometrium that has not waited for the arrival of the fertilized egg will gradually shed off the mixed blood and be excreted after losing hormone support. Therefore, if a woman has had sexual intercourse recently, does not take any contraceptive measures, and stops menstruating for more than 10 days, it is likely to be a signal of early pregnancy!

　　If early pregnancy factors are ruled out, delayed menstruation may be related to the following:

1. Contraceptives

　　So far, there are many types of contraceptives clinically, such as emergency contraceptives, long-acting contraceptives, and short-acting contraceptives. Most of these drugs play a contraceptive effect by controlling changes in hormone levels.

　　Related studies have shown that if women take multiple emergency contraceptives in a short period of time, it will affect hormone fluctuations and lead to changes in menstrual periods . In addition, if the long-acting contraceptives are taken orally, women may also experience menstrual disturbances after the drug is suddenly stopped;

2. Excessive weight loss

　　If women adopt very extreme weight loss methods, such as hunger strikes, excessive dieting, etc., it will affect the absorption of nutrients , leading to problems such as malnutrition and anemia .

　　At the same time, if the female body weight is Ouqing and the proportion of body fat is relatively low, it will affect the normal physiological function of the ovary , leading to delayed menstruation, amenorrhea and other problems;

3. Nervousness

　　If women have been under too much mental stress recently, they have not been fully relaxed. Or you have recently suffered a relatively large blow, heavy mood, anxiety and depression, which will affect the secretion of hormones in the body , and then lead to endocrine disorders .

　　You must know that the secretion of hormones by the ovary is controlled by the pituitary gland and the hypothalamus. Once the endocrine disorder is disturbed, it will affect the menstrual cramps ;

4. Smoking and drinking

　　According to related research surveys, nearly 25-32% of girls who have been smoking and drinking heavily for a long time have been sent to the hospital for examination due to irregular menstruation . Women who smoke more than 1 pack a day and drink more than 100 mg of high-strength liquor have an irregular menstruation rate that is three times that of non-smoking and drinking women .

　　All of the above factors may cause menstrual disorders. However, one point that needs to be emphasized here is that if menstruation is delayed or advanced only occasionally, most of this is related to living habits, and there is no need for you to worry too much.

　　However, if menstruation has been delayed repeatedly recently and has not improved for several months, you need to be more vigilant and seek medical attention in time to find out the reason, so as not to cause greater impact on the body.
