What are the causes of constipation?

What is constipation? Some people think that constipation means that you can't defecate for at least a week, while others think that constipation means that you can't defecate for more than three days. Regardless of the symptoms, constipation has a great impact on people's lives. If you want to completely treat constipation, you should quickly find the cause of constipation.

1. Constipation caused by dietary factors

If the food intake is small and fine, with less crude fiber, it takes longer to form feces, and a large amount of water is absorbed from the body, resulting in dry and difficult stools, and constipation.

2. Not forming a good habit of regular bowel movements in life

Many people have the urge to defecate but the surrounding environment does not allow it due to busy work, business trips, irregular lifestyles and other factors. So even if they have the urge to defecate, they have to endure it. Over time, the rectum's pressure perception of the stool decreases, resulting in no urge to defecate and constipation. Some people read books or newspapers in the toilet for a long time when they have a bowel movement, which leads to a long defecation time. Over time, it leads to habitual bowel movements for a long time and constipation.

3. Elderly and frail

Elderly and frail people and those who have been bedridden for a long time have difficulty defecating because the muscles that assist defecation are weakened.

4. Intestinal tract lesions

Intestinal lesions can cause the intestines to become narrow, resulting in difficulty in defecation, such as colorectal cancer, chronic proliferative enteritis, and postoperative intestinal adhesions. Intestinal diseases not only cause constipation, but also cause corresponding symptoms.

5. Diseases of the nervous system can also lead to constipation

Diseases of the nervous system can also cause constipation. Generally speaking, nervous system diseases that can cause constipation include brain tumors, Parkinson's disease, sacral nerve or spinal cord damage, spinal cord tumors, multiple sclerosis, etc.

6. Diseases in the large intestine can also cause constipation

Diseases in the large intestine can also cause constipation, such as irritable bowel syndrome, one type of which is called spastic constipation, which will cause a certain degree of constipation, and sometimes diarrhea and constipation will alternate.
