Hi there,
Your glucose values are fluctuating.The best way to confirm whether you have diabetes or not is to undergo a test called the"Oral Glucose Tolerance Test"That test is accepted as the gold standard.One other way is to get a glycosylated haemoglobin test-----"HbA1c" done and if the value exceeds 6, it can be taken as diabetes,but it is not a diagnostic test.Finally Lupus symptoms and symptoms of diabetes are vastly different.Yes,any sudden increase in weight gain of 60 pounds is a causative factor for diabetes.
