Hello, Your husband is suffering from dizziness and imbalance. He is a diabetic. His blood pressure is not low, blood sugar normal. He had an MRI to rule out ear and brain problems. Several conditions that cause dizziness can be related to diabetes. Consider monitoring blood sugar, diet, and type of food consumed. Your husband is advised to take home made healthy diet, do exercise as recommended, and take his prescribed medications by his treating doctor. A loss of balance, dizziness or fall can be indicative of vestibular problems or neuropathy. He should get clinically examined by a Neurologist & an ENT. He may need medications. He is suggested not to drive or do any heavy work. He should be at rest. He should be mindful of the medications he has been taking. As medication for blood pressure or water retention, can drop both the blood pressure and potassium levels, causing dizziness.
