Type 2 Diabetes Patients Who Lost Weight Soon After Diagnosis Had Better Control

People diagnosed with type 2 diabetes who lose excess weight soon after their diagnosis are up to twice as likely to maintain control of their disease than those who do not lose weight or who gain weight, according to a new study. The study is published in online in Diabetes Care, the journal of the American Diabetes Association.
Even if they regain the weight, as most in this study did, the benefits remain, the researchers found.
People who lose (excess) weight are more likely to attain their blood sugar and blood pressure goals than people who gain weight or maintain a stable weight.
When a patient is newly diagnosed with type 2 diabetes, he/she might already have lost some weight, but may still be over-weight for their height. If they try to control blood sugar with medications alone(especially medicines that increase secretion of Insulin), they will gain weight. So, if an already over-weight patient gains weight on treatment for diabetes, the chances of them attaining target treatment goals is remote.
If vigorous exercise and dieting along with Insulin sensitisers like Metformin are used, the patients may continue to loose weight while attaining normal blood sugar levels. In the long run, such patients attain treatment goals more often, as per the study.

So in management of type 2 diabetes in over-weight patients, the most important treatment is life style modification with low-carb diet and exercise.
