What causes chronic dry stools?

There are many possible causes of chronic constipation, including the following: 1. An unbalanced diet—particularly insufficient intake of fruits and vegetables—may impair normal gastrointestinal motility. 2. Frequent consumption of spicy or irritating foods may lead to “excess internal heat” (a traditional Chinese medicine concept), contributing to constipation. 3. Inadequate abdominal warmth may disrupt the balance of gut microbiota, potentially resulting in the aforementioned symptoms.
