Constipation is characterized by difficult or infrequent bowel movements. It has various causes like lack of fiber, dehydration, and certain medications. Symptoms include hard stools, abdominal pain, and straining during bowel movements. Nutrition management involves increasing fiber intake through fruits, vegetables, and whole grains as well as staying hydrated. Medical management may include over-the-counter laxatives or prescription medications if lifestyle changes are not effective in relieving constipation.
