Type 2 Diabetes in Type 1 diabetes - Double diabetes?

Yes, it can happen. It occurs when type 1 diabetes (T1D) patients develop insulin resistance, similar to type 2 diabetes (T2D).

This condition affects about 25% of T1D patients, increasing their risk of heart disease, stroke, kidney disease, and diabetic complications.

The first sign is often a higher insulin requirement (>100 units/day), along with obesity and high blood pressure.

Managing double diabetes involves dietary changes (high-fiber, low-carb diets), GLP-1 receptor agonists (GLP-1 RAs) for weight management, and metformin in select cases.

However, avoid SGLT2 inhibitors due to their high risk of diabetic ketoacidosis.

Screening for insulin resistance and metabolic syndrome is crucial to prevent complications in T1D patients.
