This gland controls hormones in the body and these hormones perform many functions. For instance, they metabolize fats and proteins and keep the blood pressure and temperature at normal levels. 

If the thyroid does not work effectively, many health problems occur. Thyroid problems are, sometimes, common in families because they pass on. In addition to passing on from one generation to another, thyroid diseases are more common in women.

Hypothyroidism VS Hyperthyroidism

Hypothyroidism is a totally different disease from hyperthyroidism. What are the differences that exist between them; let’s take a detailed look!


Hypothyroidism affects individuals when the thyroid gland does not make hormones in enough amounts to function well. As mentioned above, the production of hormones has a link with metabolism. If the production is slow or low, it will slow the metabolism.

What are the treatment options available for hyperthyroidism?

The best and most qualified endocrinologists recommend that anti-thyroid medications are an effective treatment. These medications make the thyroid gland slowly produce hormones. A development in hormones appears within weeks to months. 

Other effective treatment options against hyperthyroidism are radioiodine therapy. This therapy shrinks the size of the tumor and shows effectiveness within months. Radioiodine therapy makes your gland underactive and helps in controlling the levels of hormones.

Difference between Hypothyroidism and Hyperthyroidism

The key difference between hypothyroidism and hyperthyroidism is symptoms. As mentioned earlier, hypothyroidism causes lower levels of thyroid hormones in the body. Therefore, the symptoms, due to these low levels, reduce a decrease in metabolism.
