Diabetes, specifically type 2 diabetes, is an illness that can make you feel hungry all the time. Because of diabetes, glucose, our source of energy stays in the blood instead of spreading into our cells. This makes the person who has it feel hungry. Many celebrities, including Tom Hanks, have been diagnosed with diabetes and yet enjoy a wonderful life.
The feeling of hunger is just one of the symptoms of diabetes, which can be diagnosed via a blood test. After a proper exam, and through medication and a special diet, it can be controlled and these symptoms will be long gone.
