Our expert says:
Does smoking and then giving up have a profound influence on weight gain? Yes most people who stop smoking do gain a bit of weight as your taste sensation becomes more normal again and you may eat a bit more, and nicotine is a slight appetite suppressant.
Does smoking mess up the thyroid? Tobacco smoke contains substances that affect the function of the thyroid. One component of tobacco smoke is cyanide, which is converted to thiocyanate, which acts as an anti-thyroid agent, directly inhibiting iodide uptake and hormone synthesis. It can cause hypothyroidism according to "Cigarette Smoking and the Thyroid," featured in the October 12, 1995 issue of The New England Journal of Medicine.
Does the thyroid eventually repair itself? If just because of the smoking it probably can but if it is due to viral infection or injury or outo immune disease it won't and you would need supplements all the time.
