Loss of appetite in a 65-year-old person with Type 2 Diabetes can occur due to ageing, medication side effects, digestive issues, or other health conditions. Instead of starting appetite-stimulating medicines on your own, it is better to first identify the underlying cause with your doctor. Doctors usually recommend lifestyle measures such as eating small, frequent meals, improving meal variety, staying active, and reviewing current medications that may reduce appetite. Appetite-stimulating medicines are generally used cautiously in older adults because they may have side effects and are not always necessary.
