Vaginal bleeding in patients is usually not related to hunger. It may be caused by ovulation bleeding, acute vaginitis, cervical cancer and other factors. It is recommended that patients go to the hospital for relevant examinations in time and give appropriate treatment after clear diagnosis. 1. Ovulation bleeding: it is usually caused by the decrease of estrogen level and the shedding of small part of endometrium. There may be a small amount of coffee-colored secretion, so the patient may experience vaginal bleeding, usually lasts 2-3 days, and is not related to hunger. 2. Acute vaginitis: generally due to the patient’s frequent sexual life, do not pay attention to sexual hygiene, so that the patient is infected by Candida, viruses and other pathogens. As a result, the vaginal wall of the patient is congested and swollen, and the capillaries are ruptured, so the patient may have vaginal bleeding, which has nothing to do with hunger. 3. Cervical cancer: generally due to HPV infection, patients may have symptoms of contact vaginal bleeding in early stage. With the growth of tumor, patients in the middle and late stages may have irregular vaginal bleeding, and in serious cases, hemorrhage of blood vessels may also occur, which is generally not related to hunger. In addition, it is recommended that patients should go to the hospital in time if vaginal bleeding occurs, so as not to delay the disease and cause harm to the body.
