Hi, I am writing on behalf of my 75 year old mother who has been treated with Levothyroxine for hypothyroidism for the past 16 years. Her dosage has never been increased since treatment started (75mg). She has a few other health problems : high blood pressure (perindoperal 2mg), polymyalgia rheumatica (prednisolone10mg), arteriole fibrillation (no meds)prevention of osteoporosis (alendronic acid 75 mg) + calceolaria (2 tablets per day), stroke prevention (pravastatin 20mg). However, she still displays symptoms of hypothyroidism such as hair loss, brittle hair, cold feet, extreme tierdness, breathlessness, intermittent hoarseness of voice, thumping heart and lower abdominal pain on exertion. She has repeatedly visited her GP who maintains that her blood results are normal and no further treatment is required. Can anyone shed any light or advise as she is so lethargic she doesn't feel her life is worth living. She is also recently bereaved as my father died just under a year ago.
