I am a 65 year old male. In 1989 I was diagnosed as having over-active thyroid (Hyperthyroidism). I was placed on medication (Carbimazole) for a number of years. Then in 1992/3 I had radioactive iodine treatment! In six months' time I was asked to take a second dose of the radioactive iodine. I refused and went on using diet, exercise and other natural products to help with my condition. I was fine until I started feeling tired easily, had painful joints, racing heartbeats, palpitations etc. in 2005/6. Was then diagnosed as being hypothyroid and given Levothyroxine. I have been on this since. Dosage started from 65mcg and now I am on 175mcg! I am still with all the symptoms of hypothyroid; pemanent tiredness/fatigue, cold hands and feet, low heart rate,difficulty in thinking and remembering things especially names, PALPITATIONS. I have been a vegetarian since 1974 and I don't drink nor smoke. My weight has been fine. I have not personally been given results of my blood thyroid tests so I don't the levels of my TSH, iron, iodine etc.
As a point of interest my wife was diagnosed as having hypothyroid ( 4 years ago) and my eldest daughter is also hyperthyroid. Both are receiving medications.
