I haven't had my period for a long time, and it suddenly becomes heavy.

If menstruation does not come for a long time and then suddenly becomes heavy, this situation may involve a variety of reasons such as endocrine disorders, tumors, miscarriage or endometriosis. Each situation has its own unique mechanism and manifestations, which require our attention.

1. Endocrine disorders: Our body is like a precise clock, and the endocrine system is responsible for regulating the menstrual cycle. Changes in the levels of estrogen and progesterone affect the growth and shedding of the endometrium. If you don't have your period for a long time, it may be because the levels of these hormones are unstable or the male hormones are too high. In this case, the body may suddenly release a large amount of endometrium, resulting in heavy menstrual flow. In order to adjust the endocrine system, you can consider adjusting it through diet, exercise and medication.

2. Tumor factors: The presence of tumors may disrupt the normal function of the uterus. Whether it is a benign tumor such as uterine fibroids or a malignant tumor such as endometrial cancer or cervical cancer, it may cause abnormal bleeding. Tumors put pressure on the endometrium, causing it to proliferate abnormally and fall off. Imaging examinations can help confirm the diagnosis, and surgical treatment may be required if necessary.

3. Miscarriage after pregnancy: During pregnancy, menstruation stops naturally. If there is sudden heavy bleeding, it may be a sign of miscarriage. Miscarriage is often accompanied by severe abdominal pain and anemia, which is a situation that requires emergency treatment. Timely medical treatment can help confirm whether there is miscarriage and take appropriate measures.

4. Endometriosis: This condition is when endometrial tissue grows outside the uterus. Ectopic endometrial tissue may cause periodic bleeding, with sudden heavy menstruation as one of its manifestations. This condition may cause serious complications, and timely medical intervention is very important.

5. Lifestyle and stress: Sometimes, stress and bad lifestyle can also affect the menstrual cycle. Excessive stress, irregular diet or excessive weight loss can lead to endocrine disorders. Try to relax and maintain healthy lifestyle habits to help improve menstrual problems.

If you find that you have not had your period for a long time and your menstrual flow suddenly increases, it is recommended that you go to the hospital for a professional examination as soon as possible. The doctor will diagnose and treat according to the specific situation to avoid delaying the disease. Maintaining a healthy lifestyle and paying attention to changes in the body are important parts of maintaining women's health.
