Hormonal

Semaglutide treatment in obese patients with type 2 diabetes and severe psoriasis leads to significant improvement in psoriasis severity (PASI) and quality of life, independent of prior biologic therapy failure.

If you have severe psoriasis and type 2 diabetes, ask your doctor about GLP-1 agonists like semaglutide. This case shows it can significantly improve skin lesions and quality of life, even when other treatments failed. It addresses both conditions simultaneously.
