In some type 2 DM patients whose disease is more than 5 or 6 yrs. in duration ,the oral drugs to control blood sugar become less effective and the patient becomes partially or completely dependent on insulin
. At the same time he also starts developing microvascular complications in the form of nephropathy( kidney
involvement) , retinopathy(eye involvement) or neuropathy(nerve involvement) or macrovascular complications in the form of CAD (heart disease
) or stroke
(brain attack). In your moms case the possibility of kidney involvement should be ruled out by certain kidney specific tests or else you should consult a nephrologist
with immediate effect. Your mom has also developed eye involvement which again favors nephropathy(kidney involvement). So I would suggest you to get her to a nephrologist as early as possible for the correct and prompt management of her disease.
