Positive anti-insulin antibodies indicate that the immune system has developed an immune response to insulin, suggesting that the patient may have type 1 diabetes or insulin autoimmune syndrome. Positive anti-insulin antibodies in patients who have not used exogenous insulin are usually the result of destruction of pancreatic beta cells, indicating autoimmune damage to pancreatic beta cells and suggesting that the patient has type 1 diabetes or is at risk for developing type 1 diabetes. Insulin autoimmune syndromes are also characterized by insulin antibody positivity, one of which occurs when no exogenous insulin has been used, and is often associated with drug use. The other type occurs after the application of exogenous insulin and is often characterized by insulin resistance. Pancreatic autoantibodies are an indicator of immune damage in diabetes. If you find elevated blood glucose, you should consult a doctor in time, make a clear diagnosis under the doctor’s guidance, and have the treatment in a regular hospital to avoid delaying the condition.
