Diabetes is a condition that affects the body's ability to process blood sugar normally, leading to an excess of glucose in the blood. There are two different types of diabetes - Type-1 diabetes and Type-2 diabetes. While the former is a result of the pancreas producing little or no insulin, the latter is a lifestyle disorder, resulting from the body becoming insulin resistant. Diabetes affects millions of people in India every year and common symptoms of the condition include frequent thirst, frequent urge to urinate, fatigue and hunger and even blurred vision in some cases. Diabetics need to be very careful about what they eat on a daily and even hourly basis. Diabetics need to be extra careful of their diet. They should include food that is high on fibre content.
