'Menstrual' late? Doctor: In addition to pregnancy, most of them are 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 years, women often usher in their first "menarche", that is, the first menstruation, which is the primary feature of the ovaries starting to develop and gradually becoming ovulatory.

　　Usually, about half a year to a year after menarche, women tend to have irregular menstrual cramps each time. Sometimes there will be a second cramp every few months, half a year, or even a year or so. This is a normal physiological manifestation. .

　　As the female body continues to develop and the ovarian function becomes more and more mature, the menstrual cramps will gradually form a regular pattern. So here comes the question. The tide was very punctual before, but it was delayed this time. What's going on?

　　Women with delayed menstruation should first consider whether it is early pregnancy . You must know that the reason why the endometrium is periodically metabolized is because it changes with the ovulation and endocrine of the ovary. When the ovary releases an egg, the lining of the uterus thickens in order to allow the fertilized egg to implant and develop .

　　The inner membrane, which did not wait for the arrival of the fertilized egg, loses hormone support, and will gradually fall off the mixed blood and be excreted from the body. Therefore, if a woman has had sexual intercourse recently without taking any contraceptive measures, and has stopped menstruation for more than 10 days, it is likely to be a signal of early pregnancy!

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

1. Contraceptives

　　So far, there are many types of contraceptives in clinical practice, such as emergency contraceptives, long-acting contraceptives, short-acting contraceptives, etc. Most of these drugs are contraceptive by controlling changes in hormone levels.

　　A related research survey shows that if a woman takes multiple emergency contraceptives in a short period of time, it will affect hormone fluctuations and lead to changes in menstrual periods . In addition, if oral long-acting contraceptives are used, women may also experience menstrual disorders after abruptly stopping the use;

2. Excessive weight loss

　　If women take extreme weight loss methods, such as fasting, excessive dieting, etc., it will affect the absorption of nutrients , resulting in malnutrition, anemia and other problems.

　　At the same time, if a woman is overweight and has a relatively low percentage of body fat, it will affect the normal physiological function of the ovaries , resulting in delayed menstruation, amenorrhea and other problems;

3. Mental stress

　　If women have been under too much mental stress recently, they have not been fully relaxed. Or recently suffered a relatively big 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 hormones secreted by the ovary are controlled by the pituitary gland and the hypothalamus. Once the endocrine disorder is disturbed, it will affect the menstrual cramps ;

4. Smoking and drinking

　　A related research survey shows that among girls who smoke and drink heavily for a long time , nearly 25-32% of them have ever been to the hospital for examination due to irregular menstruation. Women who smoke more than 1 pack per day and drink more than 100 mg of high-level liquor have an irregular menstruation rate three times that of non-smoking and drinking women .

　　All of the above factors may cause menstrual disorders. However, what needs to be emphasized here is that if it is just an occasional delay or advance of menstruation, most of it is related to living habits, and there is no need to worry too much.

　　However, if menstruation has been delayed repeatedly recently, and it has not improved for several months, it is necessary to be vigilant and seek medical attention in time to find the cause, so as to avoid greater impact on the body.
