Yes, your symptoms can indeed be side effects of some of your current medications. Specifically, sertraline and nortriptyline (often prescribed for mood or nerve concerns) are well-known to cause decreased libido and weight gain. Additionally, glimepiride (used for diabetes management) can contribute to weight gain. Your other medications, telmisartan, linagliptin, and voglibose, are generally neutral regarding these side effects. Please do not stop taking any of your medications abruptly, as this can be harmful. Instead, consult your healthcare provider. They can safely review your regimen, discuss alternative medications that are weight-neutral and have fewer sexual side effects, and help you create a safe management plan.
