However, in this article we focus on weight gain that is really difficult to control, since it is one of the main problems that affect those who suffer from this thyroid problem, both physically and psychologically.

Focusing now on the relationship between hypothyroidism and weight gain, according to the American Thyroid Association, this is that basal metabolism is decreased by the lack of thyroid hormone and the body works much slower when it comes to metabolizing or processing nutrients and other substances. This produces a clear tendency to weight gain, which can range from mild to severe depending on the type of hypothyroid, since the body begins to store fats, salts and liquids very easily.
