“Most symptoms of diabetes are very subtle,” Dr. Philis-Tsimikas says. “They come on slowly and people attribute them to getting older or working long hours.” Symptoms to watch for include increased urination and thirst, fatigue, and dry or itchy skin, she adds. “These are all very non-descript and can overlap with other health issues, so the best way to look for diabetes is to take a screening test such as a fasting blood glucose and a HbA1c.”
