My 15 year old son has been a Type 1 diabetic since 13 months old. He has been suffering with swollen, puffy arms, face, dry picky skin, high bp, high cholesterol, dizziness, light-headedness, constipation off and on for a few years. The past 6 weeks he has been worse with the same symptoms but more so including nausea vomiting, trouble swallowing, sore throat, hoarse voice, severe stomach pains. Celiac screen negative. His tsh, t3 t4 R all normal but ice noticed his TPO antibodies have climbed in the past 5 years from 35 - 128 - 367 - 910 - to 1310 now is this not an obvious case of Hashimoto s ?
