Sudden heavy menstruation may be caused by physiological reasons, such as the influence of environment and emotion, or pathological reasons, such as dysfunctional uterine bleeding, endometrial cancer, submucous fibroid tumor of the uterus and other reasons.
1. Physiological causes: women are affected by environmental changes, emotions and other influences, which lead to endocrine function disorders in the body and may result in increased menstrual flow.
2. Dysfunctional uterine bleeding: If a woman is in the perimenopausal period, the hormones in her body, if disturbed, may also lead to abnormal bleeding. Perimenopausal women with decreased ovarian function will not have cyclic ovulation and will have anovulatory dysmenorrhea, resulting in a sudden increase in menstrual flow.
3. Endometrial cancer: if there is endometrial cancer or other diseases, irregular proliferation and hyperplasia of the endometrium may occur, and heavy vaginal bleeding will occur after the endometrium is shed.
4. Submucous fibroid: if a woman suffers from submucous fibroid, the fibroid makes the uterine cavity enlarged, increases the area of endometrium and affects the contraction of uterus, which causes the menstrual flow to increase.
Suddenly heavy menstruation may also have other reasons, it is recommended to go to the hospital in time, improve the examination to clarify the cause of the disease, under the guidance of the doctor to give targeted treatment or treatment.
