Hello.
Even though being
overweight does cause some amount of swelling of the feet, it is not severe enough to prescribe a diuretic. I am sure your doctor had suspected some other cause for the swelling and hence the prescription.
Generally, diseases of the heart and the kidneys cause swelling of the feet. If you are a long standing diabetic and poorly controlled, the chances of this being the case increases. I would suggest you to get a roitine urine test to see for any protein in the urine an also BNP i.e.
brain natriuretic peptide to see for the function of the heart. These tests you can get done apart from the usual bloodwork like a
complete blood count, HBA1c,
serum creatinine.
Another cause for swelling of the feet alongwith ulceration is
varicose veins. Even though, varicose veins are more common in people who spend a lot of time standing, it can occur due to obesity. You can examine both your legs yourself for any big and twisting
blue veins. If present, please go to a surgeon for further evaluation regarding the extent of the same.
Swelling of the feet alongwith redness also suggests
cellulitis, but since you donot have paon and fever, I will think it unlikely.
Your symptoms might indicate an underlying disorder which can possibly be corrected by timely intervention. Hence I suggest you visit your physician at the earliest.
Hope this helps.
Regards,
Dr Geeta
