There is not one specific reason for this, but many factors come together to cause hemorrhoids. The main causes are given below:

Main causes of hemorrhoids
Chronic Constipation: Due to the thickening of the stool, excessive pressure is exerted on the anus during defecation. This is the most important cause of hemorrhoids.

Sitting for a long time to defecate: Sitting on the toilet for a long time causes blood to pool in the veins of the anus and cause them to swell.

 

Lack of fiber-rich food: When fruits, vegetables, and grains are reduced in the diet, the stool becomes thicker and causes constipation.

Pregnancy: As the uterus enlarges, pressure increases on the veins in the anus. Therefore, hemorrhoids are very common in pregnant women.

Obesity: Obesity increases pressure on the abdomen and anus.

Heredity: If parents in the family have this problem, the risk of developing it is higher.

 

Lifestyle: Lack of exercise and working in a sedentary position for long periods of time can also be causes.
