Recent head injury, hyperthyroidism, renal artery stenosis (by dopplar studies or MRI), abnormal
kidney function (by
kidney function tests), hyper function of adrenals, Cushing’s syndrome, abnormal liver function etc would have been ruled out. You should consult a cardiologist for high BP. To diagnose the cause tests like kidney function, liver function, lipid profile, thyroid, adrenal gland function, EKG, ECHO, tread mill etc are done.
