Hypothyroidism is a lowering of the blood sugar in your body. When you are having an attack you get real shacky and must drink orange juice with added sugar or peanut butter or anything sweet to get your blood level back up again. For me this has led into Type 2 Diabetese. It may for you someday as well. However, your description of fatique along with the Hypothiroidism tells me you might need to have your thyroid glands tested. They do this with blood work and urine sample. You might need thyroid medication as well. I DID. Important you see a Dr. and don't fool around with self helps in this case. If you ARE gaining weight as i have it very well could be your thyroid. It took me six years to finally get my thyroid in the zone the drs. were pleased with and enough to tell me i can finally look forward to losing some weight now.a non functioning Thyroid inturrupts your body metabolism and wight gain is the result. Yuk! I know. But get going on the check up asap. good luck
