Why does the menstrual flow suddenly decrease?

Many girls will have menstrual problems. Once a problem occurs, timely treatment is necessary to ensure the safety and health of the patient. Especially for menstrual problems, patients should not underestimate this problem. So why does the amount of menstruation suddenly decrease? Let's ask the experts to introduce this issue.

If the menstrual cycle is basically normal but the menstrual flow is significantly reduced, or even stops with a few drops, or the menstrual period is shortened to less than two days and the menstrual flow is also small, it is called oligomenorrhea, also known as scanty menstruation. It is generally believed that menstrual volume less than 30 ml is equivalent to scanty menstruation in Western medicine. The menstrual cycle is normal, the menstrual flow is very little, or even just a few drops. There are also cases where the menstrual period is shortened to less than two days and the menstrual flow is also very little. These are the key points for the diagnosis of this disease. This disease is often a precursor to amenorrhea. Oligomenorrhea may be associated with menstrual cycle abnormalities, such as scanty early or late menstruation. If oligomenorrhea is caused by oral contraceptives or intramuscular contraceptive injections, the medication should be stopped and the disease can be treated according to the discussion and treatment of this disease.

The diagnosis of oligomenorrhea generally refers to two or more consecutive occurrences. If a woman has had normal menstruation but suddenly has less menstruation, she should be aware of whether it is a sign of threatened miscarriage in the early stages of pregnancy or a small amount of vaginal bleeding due to ectopic pregnancy. Further examinations are necessary to differentiate between the two. Be careful if the amount of menstrual blood is too little. Under normal circumstances, the amount of menstrual bleeding is about 60 ml. Less than 30 ml is too little, and more than 80 ml is too much. How do you know whether your menstrual flow is normal? Sanitary napkins can help us. Generally speaking, the dosage for each cycle should not exceed two packs (10 tablets/pack). If more than three packs are used and each tablet is soaked, it is menorrhagia; if less than one pack is used each time and the amount of blood on each tablet is very small, it is oligomenorrhea. Both situations are abnormal.

Generally speaking, light menstrual blood flow is caused by low estrogen levels. Estrogen stimulates the thickening of the endometrium in preparation for conception. If conception does not occur, the proliferating endometrium will shed and bleed to form menstruation. Low estrogen levels in the body can cause the endometrium to not grow thick enough and result in less bleeding during menstruation, which can affect conception in the future.

The above is the expert’s opinion on this issue. Treatment according to the above methods can help patients recover quickly and avoid menstruation affecting girls’ lives and health, especially avoiding infertility caused by untimely treatment. Finally, I wish the patients a speedy recovery.
