Hello, Both diabetes and hypertension are recognised as major risk factors for cardiovascular disease and when both co- exist ,the risk is not merely added up but compounded. Hypertension in diabetics is associated with increased mortality from micro as well as macro vascular complication of diabetes because both affect the same major target organs and the common denominator is the vascular tree. Left ventricular hypertrophy and coronary artery disease are much more common in diabetic hypertensive patients than in patients suffering from hypertension or diabetes alone. The combined presence of hypertension and diabetes concomitantly accelerates the decrease in renal function, the development of diabetic retinopathy and the development of cerebral diseases.  So the primary aim in you should be a meticulous control of diabetes and blood pressure and not seeing the number of tablets. Get yourself investigated thoroughly. Reduce your weight and do regular exercises. Numbness seems to be due to diabetic neuropathy and so take VIT B 12 for that. Night sweats could be due to hypoglycemia,menopause,anxiety,fear or sometimes may be a kidney infection. Consult a diabetologist and get managed and treated comprehensively  You must reduce weight and so may take the help of a dietician. Thanks
