Hi ! Good morning. i am Dr Shareef answering your query. If I were your doctor, I would see that your blood sugar is under control by doing frequent blood sugar estimation as required along with an estimation of glycosylated hemoglobin. I would also estimate your blood pressure and blood sugar level during the spells of dizziness to see if you are developing any episode of hypoglycaemia or a surge in your blood pressure. For the insomnia, I would advise you to go for a regular exercise schedule depending on your medical fitness, and if nothing helps, would take the help from a psychiatrist. You must continue your iron supplement and anti hypertensives as advised and get both these checked at frequent intervals. I hope this information would help you in discussing with your family physician/treating doctor in planning your treatment. Thanks for using the health care magic forum for your query on health. Wishing you an early recovery. Dr Shareef.
