With diet and lifestyle changes (and sometimes medication), you might be able to bring your blood sugar back down to safe levels. Some people go on to develop type 2 Diabetes. Diabetes is diagnosed if your HbAlc is equal to- or above 50mmol/mol. As well as symptoms of prediabetes, you might also experience weight loss. However, this is not good weight loss. It means that your body cells are not getting enough energy, as the glucose is staying in your blood. High blood glucose levels are very damaging to your body and can cause problems with your kidneys, eyes, legs and feet. High blood sugar levels can also damage your brain. Even if you have been diagnosed with type 2 diabetes, it's never too late to do something about your diet and lifestyle. Many people are able to reduce their blood glucose levels and no longer require medication. It's important to get dietary and lifestyle support early, so you have a better chance of reversing your diabetes, or reducing the risk of complications.
