The difference between type 1 and type 2 diabetes is as follows:

1. Type 1 diabetes is related to autoimmunity, while type 2 diabetes may be caused by poor lifestyle or genetics.

2. In terms of age of onset, most patients with type 1 diabetes develop at a younger age.

3. From the perspective of pathogenesis, type 1 diabetes is related to autoimmunity, so in the detection of antibodies, positive GATA antibodies, IAA antibodies, ICA antibodies, IA2, and Simba antibodies will appear. .

4. From the perspective of treatment methods, type 1 diabetes must be treated with insulin. If insulin is not used, it may be difficult to maintain life.

5. From the perspective of pancreatic islet function, type 1 diabetes will soon lead to an absolute lack of pancreatic islet function, while type 2 diabetes often only appears after a long period of treatment. situation.

6. Patients with type 1 diabetes may be more prone to microvascular complications, including fundus complications and renal complications.

From the above, we can see that type 1 diabetes is caused by a problem with the production of insulin, while type 2 diabetes is mainly caused by a problem with the demand for insulin. Therefore, there are fundamental differences between the two in their pathogenesis.
