My 17 year old niece has been diagnosed with Hypothyroidism since she was around 12 years old. Her doctor has not been able to control it and is trying to avoid sending her to an endo. In the last week, week and half, she has uncontrolled vomiting. No nausea, little pain, just can't keep anything down, including liquids. Her doctor thought it might be her pancreas or gall bladder and set up an appointment with a gastro. We did take her to the ER after a long day of throwing up, and her TSH level was at 37. The ER doc seems to think that her thyroid is causing the vomiting. Has anyone had any experience with that? She went back to the hospital last night with difficulty breathing and chest pains, but never got seen and left. She has an appointment with her doc today, but need some help as soon as possible.
