Hemorrhoids are a condition in which the blood vessels around the anus swell and cause pain or bleeding. This can be prevented to some extent through proper diet and lifestyle. The main causes are:
Chronic Constipation: The most important cause of hemorrhoids is constipation. Straining to pass stool puts pressure on the blood vessels in the anus and causes them to swell.
Low-fiber diet: A diet low in fruits, vegetables, and grains causes stool to become hard. A diet low in fiber slows down the digestive process and makes bowel movements difficult.
Sitting for long periods of time: People who sit in one place for hours at a time increase the pressure around the anus. This affects blood flow and increases the risk of hemorrhoids.
Pregnancy: During pregnancy, the uterus expands, putting a lot of pressure on the blood vessels below. Additionally, hormonal changes during this time can also lead to constipation.
Physical inactivity and obesity: Lack of exercise can affect bowel movements. Additionally, excess weight gain can put pressure on the abdomen and pelvic area, which can lead to piles.
