A urine test showed severe iodine deficiency from the thyroid not making enough of it. What can cause this and what kind of effects does it have on the body? I feel fatigued all the time, abnormal periods, sensitivity to cold, sleeping problems, emotional disorder, digestive problems like constipation, liquid build left side abdomen with pain all the time, short-term memory issues, light headed, dizziness sometimes, slow mentally, ringing in ears. These symptoms people told me are associated with the thyroid gland. In a way I don't know if my body is digesting food right. An ultra sound and blood work showed the thyroid was alright. I had a CT of the abdomen and pelvis. The abdomen was normal. The pelvic showed a 3cm cyst on the left ovary. The lower left is where the discomfort is and radiates up the left side of the abdomen the more I eat or drink. The comfort is relieved somewhat with a bowel movement. My body cannot have a bowel movement on its own without the use of a laxative. That has been going on for several months. The fatigue has been three years. I'm a 26 year old female. I am waiting to see what my Gyn plan is for this. My new doctor six weeks ago told me in his opinion I need an ultra sound to see if the cyst resolved and that most of the cysts resolve on their own. I see my doctor this afternoon at 2:00pm. Thanks.
