Thyroid test shows t4 1.9, tsh 0.07 is that mild hyperthyroid or severe? worried. waiting to see endo. off and on faster heart and slight hand shaking

Fairly mild: Hi. That's fairly mild hyperthyroidism, and should be tolerated OK by a 34-year old until you see the endo. Of course, those labs may not reflect a stable thyroid dysfunction, and the degree of hyperthyroidism my be in transition (becoming more or less hyperthyroid, depending on underlying cause). Your doc could give you a beta-blocker to help the heart racing and tremor until you see the endo.
