An endocrinologist has explained that early signs of diabetes can sometimes be detected by simply looking at your hands. Changes in the skin and mobility of the fingers may indicate long-term problems with blood sugar levels.
One of the warning signs is a condition known as “diabetic cheiroarthropathy” or stiff hand syndrome. In this case, the skin on the palms becomes thicker and takes on a waxy appearance, while the finger joints gradually lose flexibility. Experts note that this condition can develop in up to 30% of people who have had elevated blood sugar levels for a long period of time.
Another possible symptom is the inability to fully straighten the fingers when placing the palms together. At early stages, people may feel numbness or tingling in the hands, which later progresses into stiffness and limited movement.
Doctors also point out that if your fingers cannot properly touch when you try to bring your palms together, it may indicate damage to small blood vessels and nerve fibers caused by consistently high blood sugar levels.
Specialists emphasize that these signs do not automatically mean a person has diabetes, but they are an important reason to consult a doctor and check blood glucose levels. Early diagnosis allows timely treatment and helps prevent serious complications.
