In hyperthyroidism, if part of the thyroid is removed, does this decrease the thyroid hormone in the body?

In brief: Depends on the cause

Depends on cause.
Surgery for hyperthyroidism is either graves or hot nodule. Removing hot nodule will normalize thyroid levels. Surgery for graves is a total thyroidectomy and will require thyroid hormone replacement.

In brief: Yes, but...

If a person with an overactive thyroid producing too much hormone, then removal of half of it will leave behind a smaller hormone-producing gland.
Hormone levels might still be abnormal. The remaining gland could make too much or too little hormone, depending on how much total activity remains.
