Given your history of diabetes and a pacemaker, swelling in your hands, legs, and body, combined with urinary changes, suggests your body is retaining fluid. This could be related to your heart or kidney function. Please do not start any new medications without a doctor's evaluation. Your physician may consider prescribing a diuretic, such as furosemide, to help your body remove excess fluid or adjust your diabetes medications. However, because these symptoms require precise diagnosis, it is very important that you contact your cardiologist or primary care doctor promptly for an in-person assessment and blood tests. They will safely guide your treatment.
