Celiac disease is an autoimmune digestive condition triggered by gluten, a sticky protein found in grains such as wheat, barley, and rye. Celiac disease is typically diagnosed later in life, and occurs more often in women. Symptoms include intestinal distress, weight loss, rashes, fatigue, and nutrient deficiencies. Celiac patients must adopt a strictly gluten-free diet, which can be challenging after decades of eating gluten. Helpful strategies include creating gluten-free kitchen areas, buying naturally gluten-free items, and examining food labels.

Science has made astonishing progress in the past 60 years in many areas. Examples include the ability to repair certain defective genes, use stem cells to treat certain diseases, detect and fight many cancers, fight viruses with medications, make organ transplants work, and prevent disease with vaccines and lifestyle changes. Thanks to technological advances, doctors can also see clearly inside the body and use artificial intelligence to speed the development of new medications.

A 2025 Finnish study found that rosacea often goes undiagnosed in people ages 70 or older. Researchers say this might be due to busy physicians with limited awareness of rosacea or patients' own embarrassment or unwillingness to seek treatment.

Toasted skin syndrome is a rash that develops in a fishnet-like pattern from direct, chronic, low-level exposure to heat sources such as laptops, electric blankets, heating pads, and heated car seats. The heat dilates superficial blood vessels under the skin, causing the rash.

Red wine headaches are a common phenomenon. Scientists believe they're due to a flavonoid called quercetin, which may block a key enzyme that breaks down alcohol in the liver and allows the buildup of a chemical called acetaldehyde that can trigger headaches.

Hyperacusis describes sensitivity to some or all sounds, no matter the volume. Depending on the person, sounds might be uncomfortably loud; cause pain in the ear, head, or another part of the body; trigger negative emotional responses; or make someone dizzy. These reactions might be due to irritated or overactive nerve fibers or muscles in the ear. While doctors have few treatments for hyperacusis, certain strategies help, such as avoiding sound triggers, wearing hearing protection, and engaging in sound therapy.
