Longtime guidance about skipping nuts, seeds, and popcorn after diverticulitis is being challenged. Learn what newer research suggests about your diet.

Back and pelvic pain in people with Crohn’s can signal sacroiliitis or other joint inflammation. Learn how doctors sort this out from routine back strain.

Pain from gallstones (hardened, stonelike lumps of bile or other digestive fluids that block bile ducts) usually occurs in a distinct pattern. Gallstone attacks typically provoke steady, intense pain in the upper right abdomen that can radiate to the shoulder or back.

Not all cases of gallstones need treatment. Many people have gallstones that never cause pain or other symptoms and can be left alone. But if gallstones cause persistent pain or other symptoms, doctors often opt to surgically remove the gallbladder.

Lactose trouble that appears in midlife—plus growing sensitivities to other foods—can hint at changes in the small intestine that warrant a doctor's look.

All adults should get a lipoprotein(a) blood test at least once in their lifetime, according to the 2026 cholesterol guidelines. Also known as Lp(a), these fatty particles are similar to LDL (bad) cholesterol but more dangerous.

People who have diverticular disease have tiny pouches (diverticula) in the lining of the colon that can bleed or perforate and develop infection (called diverticulitis). People with diverticular disease should eat a healthy diet rich in fiber, drink lots of water, exercise regularly, maintain a healthy weight, not smoke, avoid straining in the bathroom, and report bleeding or pain to a doctor. However, it's not necessary to avoid eating nuts, seeds, or popcorn, which were once believed to lodge in diverticula and cause problems. That old advice turned out to be wrong.

Home microbiome tests are pricey and not yet scientifically reliable. Stay on top of your gut health by skipping the test and focusing instead on following a fiber-rich, Mediterranean-style diet that minimizes meat and processed foods.

After removal of precancerous growths (polyps) in the colon, return for a follow-up colon exam in three, five, or 10 years, depending on the number and types of growths that the doctor found and removed. A healthy diet can help prevent cancer.
