A 2026 study of more than 91,000 adults found that uninterrupted sitting raised risk for death from cancer. Replacing prolonged sitting with light, moderate, or vigorous activity significantly reduced risk, suggesting frequent movement breaks may help counter harms of sedentary behavior over time.
GLP-1 drugs, such as semaglutide and tirzepatide, used for diabetes and weight loss, may also reduce knee osteoarthritis pain and delay knee replacement surgery. In a large 2026 study, the use of any GLP-1 was linked to a reduced likelihood of knee replacement over eight years.
Lyme disease, transmitted by deer ticks, may not be detected early on. If left untreated, the infection can lead to Lyme arthritis, marked by joint swelling, often in the knee. Most cases respond to antibiotics, though some require additional treatment.
