What is the reason for constipation?

Defecation is a very normal excretion behavior of people. Defecation can excrete waste from the human body, and the main component excreted is the residue left after food digestion. This part of the substance is no longer of any use to the body, so it must be excreted. However, the process of defecation makes many people feel troubled. For example, what is the reason why many people have constipation? Let’s take a look at the relevant explanation below, I hope everyone can understand it.

1. Secondary causes

1. Mental factors: If people are mentally stimulated or overly nervous, it will lead to constipation.

2. Colonic neuromuscular disease: Pseudo-intestinal obstruction, congenital megacolon, megarectum, etc. may cause constipation.

3. Anorectal diseases: Some anorectal diseases, such as hemorrhoids and anal fissures, cause pain during defecation, leading to holding back or fear of defecation, which in turn leads to constipation.

4. Colon diseases: Colon diseases may cause colon spasms, movement disorders, and poor stool passage, such as allergic colitis and colon diverticulitis.

5. Drug abuse: People abuse drugs for a long time, which reduces the responsiveness of the intestinal wall nerve receptor cells and makes it difficult to defecate.

2. Primary Causes

1. Bad bowel habits: Many people squat on the toilet for too long, and when they can’t defecate, they strain harder to defecate. Irregular bowel movements are all causes of constipation.

2. Dietary factors: People’s improper combination of meat and vegetables in their diet, and the imbalance of coarse and fine food, leads to slow intestinal peristalsis and constipation.

3. Drinking less water: There is too much water in people’s bodies. If you don’t drink enough water, it will easily cause the stool to become dry and hard, making defecation difficult.

4. Improper bowel posture, frequent use of strong laxatives and enemas: These may cause a decrease in the sensitivity of the rectal reflex, resulting in the inability to produce the defecation reflex and causing constipation.

5. Psychological and emotional problems: Psychological depression or excessive excitement may lead to conditioned reflex disorders, thus causing constipation.
