Under active thyroid

I was diagnosed with having an under active thyroid gland last year. I take a drug to correct this but it doesn't seem to be really working. I've gained a lot of weight and find it very difficult to lose and my metabolism has really slowed down. Is this normal and what can I do to speed up my metabolism?

Hypothyroidism is the medical term used to describe an under active thyroid gland. This means that the gland is not producing sufficient thyroid hormone, which is known as thyroxine. It is most likely that the tablets you are taking are thyroxine tablets. Thyroxine affects your metabolic rate and also influences your body weight. I would question if you are currently taking a sufficient amount of thyroxine. Your doctor would be able to measure the current level of thyroxine in your blood with a simple blood test and adjust your dose of medication accordingly.
