How Does Armour Thyroid Cause Weight Loss?

Thyroid (brand name Armour Thyroid) is used to treat an underactive thyroid (hypothyroidism). Hypothyroidism is a glandular disorder caused by the unsatisfactory production of thyroid hormones. According to the Mayo Clinic, Armour Thyroid is also used to reduce enlarged thyroid glands (goiter) as well as in the treatment of thyroid cancer. Weight loss is one of several side effects linked to Armour Thyroid.

Armour Thyroid delivers the thyroid hormone that's usually made by the body. When hypothyroidism is present, your metabolism slows and can cause a number of unpleasant symptoms. These include depression, dry skin, muscle cramps, fatigue, constipation, lack of concentration and weight gain.

Armour Thyroid works to increase the body's thyroid hormone levels and ease the symptoms of hypothyroidism, including a sluggish metabolism that leads to weight gain. As your metabolism rate becomes balanced, the weight gain and other effects of hypothyroidism should begin to fade. That's why people who take Armour Thyroid might experience a minor weight loss. It can take a number of weeks before the benefits are realized.

Unless Armour Thyroid is taken in large doses, the amount of weight loss is generally insignificant. Armour Thyroid should not be taken to boost energy levels or as a diet pill for people who don't have a thyroid condition. Taking higher than prescribed doses can lead to symptoms of hyperthyroidism. Hyperthyroidism causes your thyroid gland to make an oversupply of the hormone thyroxine. The condition can lead to sudden weight loss, sweating, anxiety and an irregular heartbeat.

Keep in close contact with your doctor if you take Armour Thyroid to be reassured through blood tests that you're taking the proper dose.
