A 2024 study suggests that swapping table salt for a salt substitute can markedly lower the risk of developing high blood pressure.

About 98 million Americans have prediabetes, in which the average amount of sugar (glucose) in the blood is high but not high enough to be diagnosed as diabetes. While people with prediabetes want to avoid getting diabetes, prediabetes can be dangerous on its own, as it increases the risk for cardiovascular disease, chronic kidney disease, and fatty liver disease. Controlling blood pressure, lowering LDL (bad) cholesterol, and managing glucose levels with weight loss, exercise, and diet offers protection against diabetes and these conditions.

The average cough, typically due to a cold or other respiratory virus, lasts three weeks or less. A lingering or chronic cough lasts eight weeks or longer. Most causes of chronic cough aren't serious, such as bronchitis, seasonal allergies, or medication side effects. People should see a doctor if over-the-counter treatments haven't worked or if they experience signs such as breathlessness, wheezing, chest pain, blood in the sputum, weight loss, or fatigue. Before an appointment, people should track their cough and note its patterns to offer clues for diagnosis.

Tonsil stones are small white or yellow deposits on the tonsils. They develop when bacteria, saliva, food particles, and debris from cells lining the mouth get trapped in tiny indentations on the tonsils. While usually harmless, they can cause bad breath and sore throats.
