I was chemically poisoned with a chemical called ortho dichlorobenzene in 1981. With that happening, I have endured tremendous sensitivities to many different products and foods throughout my adult years causing loss of employment and opportunities, besides the complete deterioration of my health. Upon being diagnosed with hypothyroidism in 1994, I was prescribed Synthroid, Levothyroxine to finally Armour Thyroid, and NP Thyroid. Unfortunately, my TSH constantly fluctuated and I felt completely unwell all the time. With my own research, I discovered all contained corn or a derivative of it. Because of my corn allergy and other sensitivities, my doctor prescribed compounded desiccated thyroid. It has been a lifesaver! My TSH has been level since the change, 3 years ago. A first in 25 years! Now all my prescriptions have to be compounded.
