Many young and middle-aged women are not old, but they find that every time they have sexual intercourse, the vagina is particularly dry, accompanied by severe angular stomatitis, and even oral ulcers that do not heal for a long time. In fact, the cause of angular stomatitis and oral ulcer is the lack of vitamin B2 in the body, which is the real cause of female vaginal dryness. Vitamin B2 is a necessary substance for biological oxidation in the body. Usually, when vitamin B2 is lacking, the human body will have symptoms such as angular stomatitis, blepharitis, conjunctivitis, dry skin and desquamation.

The damage to female reproductive organs is more serious. The most typical symptoms are dryness of vaginal wall, congestion and ulceration of vaginal mucosa, which directly affects sexual desire, leading to decreased sexual desire, frigidity and sexual discomfort. In order to eradicate the "hidden secret", the general treatment method is dietotherapy first, and eat more foods rich in vitamin B2, such as milk and its products, animal liver and kidney, egg yolk, eel, carrot, mushroom, laver, celery, orange, orange and so on. If the symptoms are already serious, you can take an appropriate amount of vitamin B2 tablets on time, 3 times a day, 2 tablets each time (10 mg), and then stop taking the medicine when the symptoms improve. The first thing you need to know is that in order to distinguish abnormal secretion from normal secretion, you need to know that with the change of menstrual cycle, normal secretion will appear. & gt& gt Is your vaginal discharge normal?
