A gastroenterologist suggests four morning drinks to combat constipation, a common issue exacerbated by sedentary lifestyles and dehydration. These drinks aid bowel movements by rehydrating stool, stimulating the gastrocolic reflex, and supporting gut health. Recommended options include warm water to soften stool and water with soaked seeds like chia, which are rich in fiber. Adequate hydration is emphasized as crucial for improving digestive regularity and alleviating discomfort associated with constipation.
