A large 2024 study of more than 112,000 people found that those who ate at least five ounces of dark chocolate each week had a 21% lower risk of developing diabetes within 30 years, compared with those who rarely or never ate chocolate.

Climate change is causing longer, more intense allergy seasons, with increased amounts of pollen. This might make it harder for people to predict when their allergies might crank up, when to begin preparing for them, and how to discern the difference between allergy symptoms and upper respiratory illness. Strategies to cope include noting daily pollen counts, staying indoors when counts are high, checking with a doctor about new or worsening symptoms, and wearing a mask when outside for more than a few minutes.

Use of a continuous positive airway pressure (CPAP) system to treat sleep apnea must be monitored regularly by a doctor. This might require numerous doctor visits initially, and then annual visits afterward to make sure the therapy is still working effectively. The clinician needs to review data collected by the machine, gather information from the patient, and determine if new health conditions, including weight gain or other sleep issues, require adjustments to the CPAP machine settings.

Generalized itching is common and has many potential causes. Examples include skin changes that occur with age; skin conditions; and many other diseases such as diabetes, thyroid disease, kidney disease, and liver disease. Relief involves treating underlying conditions; using medications that ease itching; bathing with lukewarm rather than hot water; using soap only on the armpits, genitals, feet, and face; and moisturizing immediately after showering or bathing.

Doctors are rethinking their recommendations about a supplement used to help slow dry age-related macular degeneration (AMD). They're advising people to keep taking the pill even when they reach the late stage of the disease. Previously, the supplement—a cocktail of antioxidant nutrients known as the AREDS2 formula—was believed to slow disease progression only in the beginning and intermediate stages of dry AMD. New evidence suggests the supplement might also slow vision loss in late-stage dry AMD.

Dentists can help detect health problems far beyond the mouth. These conditions include oral cancer, diabetes, sleep apnea, osteoporosis, acid reflux, and eating disorders. People can maximize their dental check-ups by sharing health updates and voicing health concerns. Only two-thirds of Americans visited the dentist in the past year, and many avoid dental visits due to fear or embarrassment. There are many strategies to help people tamp down these emotions, including music, relaxation, and medication.
