What causes constipation in infants?

The main causes of infant constipation include the following: 1. Dietary factors: Insufficient food intake in infants leads to reduced digestive residue, resulting in decreased and thickened stools. Inadequate sugar content in milk or lack of dietary fiber may also trigger constipation. 2. Inadequate fluid intake: Failure of caregivers to provide sufficient fluids promptly can cause dehydration, leading to dry stools and difficulty in defecation. 3. Intestinal development issues: Some infants may have intestinal developmental abnormalities, such as Hirschsprung's disease (congenital megacolon), which can impair bowel function. 4. Lifestyle habits: Lack of established regular bowel habits and suppression of the urge to defecate can cause stools to remain in the intestine for too long. 5. Psychological factors: Sudden external stressors or an unstable living environment may lead to emotional instability in infants, which can also contribute to constipation. Individuals with concerns should seek timely medical consultation.
