A fading sense of smell is common with age but can signal other problems. Learn when to seek testing and which treatable issues may be involved.

Diminished flavor can stem from aging, nasal issues, infections, or certain blood pressure drugs. Small medication tweaks and habits may help restore it.

Tongue swelling can stem from drug reactions, infections, vitamin deficits, thyroid issues, or rare disorders. Learn which clues help sort out the cause.

A constant drip in the back of your throat isn’t always from a cold. Saline rinses, humid air, and cautious decongestant use may all help put an end to postnasal drip.

A 2025 analysis found hearing loss in 41% to 72% of people with diabetes, which was, on average, more than four times as often as in people without diabetes. People whose diabetes was less well controlled had greater hearing loss. Diabetes lasting 10 years or more doubled the risk.

The term ototoxicity describes inner ear damage from drugs that can cause tinnitus (ringing in the ears), and affect hearing and sometimes balance. Medications more likely to cause ototoxicity include aspirin; the antibiotics azithromycin and clarithromycin; certain chemotherapy drugs; loop diuretics such as furosemide (Lasix); and some biologics. These drugs can damage hearing by injuring hairlike projections in the inner ear. People taking ototoxic drugs should get their hearing tested before, during, and after using the drug.

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.

Havard researchers have identified biomarkers that appear to capture tinnitus severity for the first time. Scientists made the connection after analyzing the facial responses and pupil dilation of study participants as they listened to pleasant, neutral, or unpleasant sounds. The findings, when fed to a computer model, accurately predicted the severity of symptoms participants had reported on questionnaires. Scientists hope the biomarkers will lead to tools that gauge tinnitus severity and treatment effectiveness.
