Your digestive system

What's happening

Age-related changes in the large intestine can lead to more constipation in older adults. Other factors that play roles in constipation include a lack of exercise, not drinking enough fluids and a low-fiber diet. Some medicines also can play a part, such as diuretics, certain antidepressants and iron supplements. So can certain health conditions, such as diabetes and pelvic floor disorders.

What you can do

To help prevent constipation:

• Eat a healthy diet. Eat high-fiber foods such as fruits, vegetables and whole grains. Limit high-fat meats, dairy products and sweets because they can cause constipation. Drink plenty of water and other fluids.
• Include physical activity in your daily routine. Regular physical activity can help prevent constipation.
• Don't ignore the urge to have a bowel movement. Holding in a bowel movement for too long can cause constipation.
