Constipation: Nearly everyone faces it at some point. The inability to pass a bowel movement can be frustrating and painful, but drinking plenty of water and eating fiber-rich foods may bring relief. If that doesn't work, stimulant laxatives irritate the intestinal lining, helping to induce bowel movements. Make sure to read labels carefully and follow the appropriate dosage.
