A meatball growing in the anus after the birth of a second child may be due to hemorrhoids. Pregnancy and childbirth lead to increased pressure in the abdominal cavity. The fetus and enlarged uterus exert pressure on the rectum and anal canal, causing varicose veins in the area to form clusters of veins, and meatball-like tissue may appear at the anal opening, forming hemorrhoids. Patients may experience symptoms such as blood in the stool and perianal itching, and when hemorrhoidal nuclei become embedded there may be severe pain in the perianal area and anal bruising. After giving birth to a second child after the anus grows a meatball, it is recommended to go to the hospital in a timely manner, under the guidance of the physician to carry out the relevant treatment, usually to maintain a healthy diet and defecation habits, drink more water, eat more fiber-rich food, regular defecation, prevention of constipation, in order to prevent the aggravation of the condition.
