Does suppressing tsh - high t4 cause weight gain?

No: It is an inverse relation. The higher the T4 the lower the tsh. So if your TSH is very low it may mean yoiur thyroid is too high. Normally a low TSH and a high T4 would mean you are hyperthyroid. A hyperthyroid person tends to lose weight, have heat intolerance, irritability and a tendency for loose bm.

No weight loss: High T4 and low TSH means the thyroid gland is overactive and producing more thyroid hormone.That speeds up your metabolism and you end up losing weight.Reverse is true if your TSH is high and T4 is low, in that case you end up gaining weight.
