This is my first post but have been following for a while. I had half my thyroid removed 8 years ago, been on 100 mg levothryoid for 6 years and had to give up work 3 years ago due to ill health. Last year my digestive system seemed to give up and I was relying on fasting and copious amounts of senna pod tea to get things moving and the expensive cold lazer treatment on my horrible fungal toenails failed. No help from my GP of course. So I started trying to investigate and found this forum and discovered low temperature/basel metabolic rate seemed to be the cause. Iodine was prescribed on several websites viewed so I decided to give it a go. Nothing ventured nothing gained. Interestingly my temperature went up from mid 34s to 35.9, the water retention disappeared and my digestive system, well, oh the bliss of regular movements! On the down side I noticed my skin was a lot dryer. I am now taking only half a tablet every other day because I started to get itchy skin and unfortunately the slow digestion and water retention has returned. I assume the rise in temperature and speedy digestion is just the body's reaction to something it doesn't like. So, like everyone on here I will have to wait until our national treasure of a health service gets round to acknowledging that our symptoms are due to an ineffective synthetic drug.
