What is Diabetes? Also known as a silent killer, Diabetes is a disorder that can lead to several life-threatening complications. Here is a side of India which we must acquaint ourselves with that India is among the top three countries in the world with the highest diabetic population. At Doctor Saab, we repeatedly reinforce that Diabetes is a disorder and not a disease. It is a condition that is very much in our control to manage. It is the core belief that drives our team of highly skilled and experienced diabetologists.
