Other Comments
Obstruction of the esophagus, stomach, small intestine, and colon has occurred when bulk-forming laxatives are administered without adequate fluids or in patients with intestinal stenosis.
Clinical studies have shown that 7 g per day of soluble fiber from psyllium husk may help reduce the risk of heart disease when used as part of a diet low in saturated fat and cholesterol.
