In patients with IBS-C, fiber supplements may help soften stools and decrease straining, but may also lead to increased gas production and bloating. Osmotic laxatives like milk of magnesia are frequently used to soften stools and increase stool frequency in IBS-C patients.

On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.
