The menstrual flow of a normal woman is about 3 ml to 8 ml. If the menstrual blood volume is less than 3 millilitres, it is called oligomenorrhea, which needs our attention, because it may lead to abnormal ovulation, or even infertility in the long run, so it needs timely treatment. So, what's wrong with less menstruation than before? What is the reason for less menstruation than before? < P > The reasons for less menstruation mainly include the following three aspects:

1. Uterine dysplasia. Menstruation is endometrial exfoliation and bleeding accompanied by ovarian cycle changes. If the uterus is underdeveloped, such as the uterus is small or abnormal, only a small amount of endometrium falls off in each physiological cycle, resulting in less menstrual flow. In addition, endometrial tuberculosis causes endometrial lesions or curettage, which leads to endometrial damage, and there will also be less menstrual flow or even amenorrhea.

2. Abnormal hormone secretion. Estrogen can stimulate the proliferation of women's endometrium. If the hormone secretion in the body is abnormal, it will lead to the hyperplasia of endometrium not reaching the required thickness, resulting in less menstrual flow. Excessive dieting, excessive work and rest, bad mood and reproductive system diseases will all affect the endocrine environment of women, leading to abnormal hormone secretion and less menstrual flow.

3, anovulatory menstruation. Anovulatory women will also have menstruation, which is medically called "anovulatory menstruation". This is different from normal menstruation and belongs to the category of "functional uterine bleeding". This kind of menstruation is characterized by irregular time and little blood.

how to adjust the amount of menstruation? Besides food, we can also adjust menstruation by changing living habits and avoiding mental stimulation. During menstruation, women should keep warm and avoid cold stimulation, especially pay attention not to eat cold food. In addition, to avoid overwork and keep a happy mood, these methods have a good effect on menstrual conditioning, thus preventing the symptoms of less menstrual flow. What's the matter with excessive menstruation on the second day?

1. Due to the excessive secretion of ovarian estrogen, long-term stimulation of endometrium makes it proliferate beyond the normal thickness, so the amount of bleeding increases when it falls off, such as anovulatory functional uterine bleeding.

2. Excessive menstrual flow in women may be uterine fibroids. Endometrial bleeding is the main symptom of hysteromyoma, but most patients with endometrial bleeding often show periodic menstrual blood increase and irregular menstruation. If menstruation suddenly becomes irregular, or in one of the following circumstances, you should be vigilant: menorrhagia, bleeding is periodic, often accompanied by prolonged menstruation; Shortened menstrual cycle and more menstrual flow; Irregular bleeding, abnormal menstrual cycle, long and short menstrual flow, endless dripping and long duration.

3. Inflammation of reproductive organs. Vaginal bleeding is often accompanied by pain in the lower abdomen or waist, increased vaginal discharge, abnormal color or smell, fever, frequent urination and pain, so it is necessary to consider the infection of reproductive organs.

4. Cervical hypertrophy. Cervical hypertrophy is a kind of chronic cervicitis, the main symptoms are menorrhagia, purulent leucorrhea, dysmenorrhea, pain in the lower abdomen and lumbosacral region, or frequent urination, urgency, dysuria and sexual bleeding. Severe cases can cause endometritis, tubal oophoritis and tubal adhesions, leading to infertility and increasing the probability of inducing cervical cancer.

5, blood disease. Such as leukemia, aplastic anemia, thrombocytopenic purpura and pernicious anemia.
