Diabetes is a medical condition where blood sugar levels are constantly higher than the normal range for an extended period of time. It is a chronic condition but needn’t be worried about as it can be managed through proper diet and medication. Insulin is a hormone produced by the pancreas that helps the body in the process of blood sugar regulation. When it comes to a diabetic person, one possibility would be the pancreas not producing enough insulin for the glucose to be regulated. There might be another possibility where the body does not use the produced insulin effectively to regulate blood sugar levels.
