Gaining Weight

Another typical sign of hypothyroidism is unexpected weight gain. Low-thyroid people not only move less, but they also tell their livers, muscles, and adipose tissue to store calories. When thyroid levels are low, metabolism shifts into a different mode. Instead of burning calories for development and exercise, your basal metabolic rate, or the amount of energy you consume at rest, falls. As a result, your body tends to retain more dietary calories as fat. As a result, even if the quantity of calories consumed remains constant, low thyroid hormone levels might promote weight gain.

In fact, persons with newly diagnosed hypothyroidism gained an average of 15-30 pounds (7-14 kg) in the year after their diagnosis, according to one research. If you've been gaining weight, first assess whether other changes in your lifestyle may be to blame. Bring it up with your doctor if you're gaining weight despite a healthy diet and exercise routine. It might be a sign of something else going on.
