My daughter is 31 years old and had her thyroid removed for multicystic goiters 10 years ago. She is currently on Synthroid. She has a concerning weight gain (50 pounds), hot all the time, and fatigue. At the end of the day she feels like she just can’t go another minute. She has dieted and exercises but unable to get control of these health concerns. She is a registered nurse so is educated in health care but it seems there is nothing to be done. She also has had psoriasis since childhood that are a constant source of uncomfort. I am not a nurse but do have education in healthcare. I feel like the bulk of her problems stem from her thyroid. The doctors do blood test on her and they come back normal. other than the psoriasis and ear/throat infections as a child she was very healthy prior to the thyroid disease. Any input or suggestions on treatment/diagnosis would be most appreciated. I am really worried about the well being of my daughter.
