Constipation refers to infrequent bowel movements or difficulty passing bowel movements. If you suffer from constipation, you may find that your stool is very dry and hard, and passing them may be painful.
Constipation, either by itself or alternating with diarrhea, may be a symptom of irritable bowel syndrome (IBS) or other bowel conditions.
If you become unable to pass stools or gas, you may be suffering from fecal impaction. This needs immediate treatment, as it can quickly progress to bowel obstruction.
