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.

A new, tender lump in a man’s breast doesn't necessarily mean cancer. But it should not be ignored. Gynecomastia is one possible cause, but there are others.

An elevated lymphocyte count usually indicates a simple viral illness. Less often, it could indicate a blood cancer. How the number is calculated shapes what it may mean.

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.

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.

Nonmelanoma skin cancers are unlikely to be life-threatening, but they can cause disfiguration and other problems. The cancers should be removed.

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.
