If you increase your thyroid medication can you go from hypothyroidism to hyperthyroidism?

Technically, no. You can be overtreated and your thyroid hormone levels can be too high, but technically speaking, your thyroid is not over active.
Yes. That's why ugly should get blood tests ~ 6-8 weeks after a change in your levothyroxine/synthroid dose, to make sure you're not getting too much medication. After you're steady on a dose, less frequent blood test is needed, unless u develop symptoms. Some thyroid conditions have periods of highs and lows too, in the natural disease course (which require med dose changes)...See ur endo to ask.
Yes. That is why it is important to be monitored by your doctor regularly.

I have hypothyroidism but my doc said I may have hyperthyroidism as well. Could smoking marijuana have caused this or affect my thyroid at all?

Unlikely . Though certain thyroid conditions can cause both hypo and hyper thyroidism at one point or another, both cannot exist at the same time. It would be like saying your gas tank is full and empty at the same time. At this time there aren't any conclusive studies showing that chronic marijuana use directly affects thyroid function. However, marijuana does affect other hormones. Read more...

My thyroid scan/uptake shows mild hyperthyroidism, but blood-work shows hypothyroidism. Does this happen often? What should I do?

Reverse T3 (liothyronine) Thyroid scan/uptake shows mild hyperthyroidism, but blood-work shows hypothyroidism. Thyroid gland is working hard but producing ineffective hormone. Test for reverse t3 (liothyronine). Thyroid hormone replacement is reasonable. Possible mutations in the sbp2 gene: abnormal thyroid function tests, low triiodothyronine (t3 (liothyronine)), high thyroxine (t4) and reverse t3 (liothyronine), and slightly elevated thyrotropin.

Antibodies. You probably have several types of thyroid antibodies floating around your system. Some cause hyperthyroidism while others may block their effect on the thyroid receptor. Treat your levels- if you're hypo - treat with synthroid (thyroxine). Monitor function and antibody levels over time. Read more...

Labs are right. Thyroid scan/uptake shows how active someone's thyroid is in trapping iodine, but not whether or not their thyroid is able to convert iodide to iodine and make thyroid hormone with it. In this situation, the labs tell the true story - that the thyroid can't make enough thyroid hormone. Uptakes and scans are morehelpful in people with hyperthyroidism, and don't add much info in hypothyroidism. Read more...
