What is Diabetes? What are its symptoms?
- Diabetes is a chronic condition caused when the pancreas produces insufficient quantities of the hormone insulin, or when our body cannot effectively utilize the insulin it produces. Insulin is the hormone in our bodies that regulates blood sugar.
- Type 1 Diabetes is a condition where the body has deficient insulin production and requires daily doses of insulin. Why Type 1 diabetes occurs is not known and it is not preventable as on date. The main symptoms include frequent passage of urine, excessive thirst, constant pangs of hunger, unexplained weight loss, changes in vision and tiredness.
- Type 2 Diabetes is caused by the body s ineffective use of insulin due to overweight and lack of physical activity. 90% of people with diabetes around the world have Type 2 diabetes.
- Symptoms could be similar to Type 1 diabetes, but often latent or non-specific. Lately, Type 2 diabetes is also increasing among children.
- Gestational Diabetes Mellitus is defined as glucose intolerance with onset or first recognition during pregnancy[viii]. Women without previously diagnosed diabetic conditions exhibit high blood glucose levels during pregnancy mostly during their third trimester. Women with gestational diabetes are at an increased risk of complications during pregnancy and at delivery. They are also at increased risk of type 2 diabetes in the future.
- Impaired glucose tolerance (IGT) and impaired fasting glycaemia (IFG) are intermediate conditions between being normal and having diabetes. People with IGT or IFG are at high risk of progressing to type 2 diabetes. (Read: World Health Day 350 million diabetics to double in 20 years)
