Our feet often act as health indicators. Many health problems are revealed early through the feet. They can be seen as a health barometer. Diabetic foot is one of the most important types of diabetes that affects a large part of the population in India. The feet reveal the severity and onset of diabetes. Estimates indicate that 77 million people above the age of 18 in India have type 2 diabetes. It starts when insulin resistance starts in the cells. Type 2 diabetes can be controlled by controlling many factors such as obesity and lifestyle. Our feet are the telltale signs that diabetes is getting serious. Dr Rajeev Premnath, General Laparoscopic Surgeon and Endoscopist, Minimally Invasive Proctology Department at Ramakrishna Hospital, Bengaluru explains about this.
