I have currently been on Levothyroxine 150mcgs a day for 11 years. For the last 5 years or so i haven't felt any better. I'm tired all the time, even though i get 8 hours sleep every night. I'm very active and like to run. Have just finished a half marathon for charity. But tiredness getting the better of me. My other symptom which i have never managed to control even after seeing a gastro doctor for several years, is constipation. I'm constantly bloated and even with my good diet and exercise struggle to lose weight. I'm not overweight but Ive put on a few pounds over the last few years which i cant shift even though Im running up to 12 miles a week. I walk everywhere too. I have been back and forth to my doctors, and they keep checking my thyroid and saying its fine. I was on 125mcgs up to a few years ago and then they upped to 150. My father has an under active thyroid, as does my Mother & 2 sisters. I also believe so did my gran and several of my aunties, so it definitely runs in our family. I have also recently been diagnosed with high blood pressure (so im on medication for this), and yesterday after being back at docs and having ferritin levels of 16 on two past readings, have now been prescribed iron tablets. I hate taking all this medication. I feel the doctors know nothing about Thyroid disease so they just throw tablets at it. Ive never been given any information as how best to take medicine and food diet etc. I love Cabbage, sprouts and broccoli and eat it with every meal, but reading a website yesterday, it advised staying away from these veg. So if anybody can offer any help, diet advice or anything i would greatly appreciate it. I'm 42 but feel 102.
