Normally, a menstrual bleeding is around 60 ml, below 30 ml is too little and above 80 ml is too much. The most important reasons for too little menstrual blood are high stress and reduced sex life. Women whose menstrual blood becomes less heavy but whose periods are regular are less likely to come to consult a doctor. As a matter of fact, the life of modern women is very stressful. After giving birth to a child, many women have to go out to work in addition to taking care of the child and running the household, so they are under pressure and have less sex, which leads to insufficient secretion of hormones and increases the chances of having a low menstrual flow. Secondly, because of the openness of sexual concepts, frequent abortions caused by endometrial injuries and adhesions, which led to a decrease in menstrual flow, and some patients even stop menstruating due to cervical obstruction. Thirdly, the ovarian function declines prematurely. Women whose ovaries decline prematurely or who are close to menopause will have less menstrual blood, often preceded by progesterone deficiency, which means that there will be a small amount of bleeding for a few days before menstruation begins to actually occur. A blood test is usually performed to determine whether the problem is with the ovaries or the pituitary gland. Next, basal body temperature is measured and charted to see if ovulation is occurring or if there is a progesterone deficiency. Ultrasound can also be used to detect the thickness of the uterine lining and whether ovulation is occurring. If the blockage of the cervix is caused by uterine adhesions, hysteroscopy can be used to separate the cervix and insert a contraceptive device, followed by hormone treatment for 3 months. If the progesterone is insufficient, estrogen can be supplemented or ovarian therapy can be used to supplement estrogen to achieve the purpose of treatment. Relaxing and reducing stress in your life will also help your periods return to normal. Both heavy and light periods are considered menstrual irregularities. Irregular menstruation can lead to iron deficiency anemia, which is a common gynecological disease.
