Can there be a thyroid disorder similar to graves disease but with weight gain instead?

Could be Graves': I know the textbooks generally say that graves' is associated with weight loss, but I have had many graves' patients tell me that they had actually gained weight instead.

Not sure of question: Graves disease is a specific entity. Weight gain can be a sign of inappropriate thyroid or possible multiple endocrine problems like diabetes or pituitary gland abnormality. This also can be dietary indescetion.
