Patient's question:
During non-menstrual periods, if there is a small amount of vaginal bleeding accompanied by mild right lower abdominal pain, what are the possible conditions?Doctor's answer:
Generally, non-menstrual vaginal bleeding can be caused by the following conditions:1. Ovulatory bleeding is a term people often hear. In Western medicine, it is called ovulatory bleeding, while in Traditional Chinese Medicine, it is referred to as "intermenstrual bleeding." This occurs due to a temporary decline in estrogen levels, causing the endometrium to partially shed without hormonal support, resulting in regular vaginal bleeding. The bleeding volume is usually small, with some people experiencing only a small amount of brownish discharge. It typically lasts for half a day or 2-3 days, and not more than 7 days, sometimes accompanied by mild ovulation pain and lower back discomfort. For those measuring basal body temperature, this bleeding usually occurs during the transition from low to high temperature.
2. Functional uterine bleeding, commonly known as "Dysfunctional Uterine Bleeding" (DUB), is very common in clinical practice. It is primarily caused by dysfunction of the neuroendocrine system that regulates reproduction. Its symptoms often include irregular menstrual cycles, excessive menstrual flow, prolonged periods, or irregular bleeding. The treatment principle is to stop bleeding quickly, then adjust and establish a normal menstrual cycle, and prevent recurrence. Due to prolonged bleeding, some people may also experience varying degrees of anemia, so correcting anemia is also important.
3. If bleeding occurs 7-10 days after a delayed period, it should not be assumed to be simply a delayed menstrual cycle. It is important to observe whether the bleeding volume, color, and duration are similar to normal menstruation. If the bleeding is intermittent, with varying amounts and accompanied by abdominal pain, it is necessary to be cautious of ectopic pregnancy or threatened miscarriage. If the bleeding is heavier than usual, lasts longer, and is accompanied by significant menstrual cramps, it may indicate uterine fibroids or endometriosis.
