Dr. Shen Yonghua
Constipation is one of the common symptoms of the digestive system, characterized by reduced frequency of bowel movements, hard stools, or difficulty in defecation. The main causes of constipation can be summarized as follows:
1. Improper diet: A low-fiber diet is one of the primary causes of constipation. Dietary fiber helps promote intestinal motility and increases stool bulk. Insufficient intake may lead to dry, hard stools and difficulty in passing bowel movements.
2. Lifestyle habits: Habits such as delaying bowel movements, inadequate water intake, and lack of physical activity can all contribute to constipation. For example, during busy work periods or while traveling, people may postpone defecation, causing stool to remain in the intestine for too long and excessive water to be absorbed, resulting in dry and difficult-to-pass stools.
3. Diseases and medication effects: Certain diseases, such as anorectal disorders and neurological conditions, as well as side effects of some medications, such as opioid painkillers, antidepressants, and calcium channel blockers, may inhibit intestinal motility and lead to constipation.
4. Age factor: With advancing age, older adults often experience weakened intestinal motility and reduced muscle tone, making them more prone to chronic constipation.
