I am a mum age 36, diagnosed hypothyroid age 16. it has been continually monitored through out with increased levo requirements - up to 300mg daily after birth of my second daughter. and weighing in in excess of 17st. 4 years ago I managed to loose nearly 7st and I was healthy full of energy, running 3 5km runs a week and chasing after my young kids. Since I have restarted career and over last year I have lumped on 4 st. doctor re tested my thyroid and told my I was extremely OVER active and slashed my level in half to 150mg daily. I am bloated, piling on weight, my skin is so dry its painful, I am exhausted - regularly have to go and have a nap in car mid afternoon as I just cant continue and for the first time in my life I am depressed. - actually really low mood I feel like I am being pushed down from above and cannot raise my self back up. My doctor will not see my until 10th Feb to review further. All research I can see is linking it all back to thyroid but wondering is anyone uses B12 - symptoms are very similar if I could boost that might it help me survive until I can see doctor again?
