Obtain a detailed clinical history
and a thorough clinical examination to determine the systemic involvement of
DM (coronary artery disease, arterial hypertension, nephropathy, neuropathy,
retinopathy) and the degree of hearing loss and vestibular impairment.
Review the treatment for DM (actual blood glucose level, glycemia control,
diabetic medication regimen). Evaluate cardiac function
(electrocardiography, exercise electrocardiography, echocardiogram),
neurologic function (peripheral and autonomic neuropathy), and renal
function (urea, creatinine, electrolytes, glomerular filtration rate). Blood
work should include a complete blood count.
