As with many other conditions, there are risk factors that increase the chances of becoming constipated. A diet low in fiber is probably the best-known risk factor. Women are more susceptible to constipation than are men. The chances of developing constipation increase with age, as older people have slower metabolisms and weaker muscles in their digestive tracts. They are also usually less physically active than younger people, and lack of exercise also increases the risk of becoming constipated. Some mental health conditions, like an eating disorder or depression, also increase the risk of constipation. Patients who take certain medications also have an increased risk of becoming constipated.
