What is Hyperthyroidism?
The thyroid is a small gland located in the neck that controls metabolism, energy production, and many body functions. What is hyperthyroidism? It is a condition where the thyroid gland produces too much thyroid hormone. As a result, the body burns calories faster than normal, leading to rapid weight loss and other health problems.
Many people wonder, can hyperthyroidism cause weight loss? Yes, it is one of the most common symptoms. Even if a person eats more food than usual, they may still continue losing weight because the metabolism becomes overactive.
