An estimated 50 percent of older adults rely on nonbulk forming laxatives for regularity. Frequent use of these laxatives lowers the level of the blood protein albumin. Research suggests that lower than normal albumin levels may increase your risk of heart disease and cancer. Instead, try a more natural approach to regularity–increase your intake of fluids and fiber-rich foods such as whole grains, fruits and vegetables, and increase your level of physical activity.
