A big pile of leucorrhea the day after intercourse may be due to increased glandular secretion, semen mixed with some secretions formed in the acidic environment of the vagina, or it may be related to factors such as vaginal inflammation. The human nerve center is in a hyperactive state during intercourse, stimulating the ovaries to produce more estrogen. Under the effect of estrogen, the cervical glands secrete a lot of fluid, while the vaginal wall is stimulated by friction and also produces a lot of exudate, which is mixed with semen and formed in an acidic environment. This is a normal phenomenon and patients do not need to worry too much about it. Patients may also have symptoms such as painful urination, burning pain and white curd-like or beanbag-like leucorrhoea. At this time, patients should take clotrimazole, miconazole, mycobacterium, fluconazole and other drugs for treatment under the guidance of doctors. In addition, avoid eating greasy and spicy things, such as fried chicken, chili, etc., which are not conducive to recovery.
