There is a huge national study to prove what is best to prevent type II diabetes. It is great that you know your risk. Follow an active lifestyle, and healthy eating will make a difference. Getting an earlier diagnosis rather than a later one is very important. Pretending that diabetes does not exist does not work.
Health problems can occur when blood sugars stay high.
I applaud you in paying attention. My cousin has all of the signs, but her sugars are normal or sometimes low. It sounds like she may have hypoglycemia with symptoms including the shakes, sweats, dizzy, and weakness when blood sugars go below normal. For many people, hypoglycemia occurs before developing diabetes. That is not the case with everyone.
