Most of us don't think twice about standing up, but for people affected by postural orthostatic tachycardia syndrome (POTS), standing can provoke lightheadedness and a racing heartbeat. While some people with POTS will require medications, most will improve with some specific dietary and behavioral changes.

Postural orthostatic tachycardia syndrome (POTS) is a condition characterized by lightheadedness or dizziness when standing and a racing heart.

In 2024, the FDA approved the sale of pivmecillinam (Pivya), an antibiotic to treat urinary tract infections (UTIs) in women. When the drug becomes available in 2025, it will join the lineup of existing first-line antibiotic treatments for UTIs, such as trimethoprim/sulfamethoxazole (Bactrim) and nitrofurantoin (Macrobid). Doctors say having another treatment option on the same tier will be helpful, since some germs that cause UTIs have become resistant to existing antibiotics.

Specific exercise routines can be designed around a person's type of arthritis, severity, and location, but usually focus on three areas: stretching, strength training, and low-impact aerobics.
