Hello, Its been awhile since ive been on . I recently found another doctor and he is trying to help me with my symptoms. This is my question. I had a thyroid ultrasound in November of 2016, the new doctor ordered a new ultrasound. The right lobe went from 4.5x1.4x1.9 to 4.9x1.4x1.9 (5/1/17) . The left lobe was 4.7x1.4x1.8 and now it is 5.1x1.8x1.8cm . So my question is , does a normal thyroid change or enlarge, or is this part of thyroid disease. To give you a little history, my mom, grandma and uncles all have hypothyroidism. I have been feeling tired, weak, sore and gaining weight for almost 2 years now. My Tsh has gone from 1.7 to 2.3 to 3.3 to 3.9 to 2.3. I also had my TPO tested and it was high for antibodies. My newest symptoms now involve, constipation and sore throat with a feeling of choking and something in there. Im waiting to go back to my doctor to discuss the recent ultrasound. I actually could see my results through my insurance , but have not talked to my doctor yet. I did see in comments on ultrasound Iodine deficiency diffuse epidemic goiter. Not sure what that all means if its thyroid disease or if i just need Iodine. Id would appreciate any advice and if the thyroid is suppose to change in size? Is this Normal?
