Brief Answer: Problems could be due to high BP, infection Detailed Answer: Hi XXXXXXX Thanks for your query. Firstly, in order to PINPOINT the exact cause of her problems; give you a SOUND professional advice; and, TRUE VALUE FOR YOUR MONEY, I request you to kindly provide additional information as follows :- * Her medications along with the dose and frequency, for high blood pressure and hypothyroidism * Her Blood Pressure readings (both systolic and diastolic- both are equally important), apart from that recorded during Holter * Her latest test reports, including that of blood sugar, TSH levels; Urea & creatinine; CT scan of brain if done. * The report of holter as given by your cardiologist. * Does she have any urine infection (burning sensation while passing urine, frequently going to the bathroom). * Features of depression, forgetfulness if any. This notwithstanding, from the brief information available, the lightheadedness and dizziness and malaise may be due to:- - uncontrolled blood pressure or the medications for same - reduced blood supply to the brain due to narrowing of blood vessels (due to clogging following deposition of cholesterol in the form of plaques) which supply blood to the brain - small, pin-point size infarcts in the brain due to uncontrolled blood pressure. * Her general feeling of malaise and weight loss may be due to - a silent infection, which is quite common in elderly people. - overdose of eltroxin which causes hyperthyroid state. - or, undiagnosed diabetes, which is quite common at this age. Consult your doctor and apprise him of my opinion. I am certain that he agrees with my opinion and clinical acumen; order - CBC to indicate silent infections, if any; - CT scan of Brain (for brain infarcts) and, other required tests including - kidney function tests, - blood sugar (if not already done) to confirm/rule out diabetes; - chest-X-ray lungs' condition and heart size, and - serum electrolytes, for sodium and potassium derangements On receipt the additional information, I will analyze your mother's case in its entirety, and then give you a sound professional advice about medication of treatment if required; further investigations if required and, guide you in detail, about what course of action would be best for her.
