Before birth and throughout childhood, the thymus is instrumental in the production and maturation of T-lymphocytes or T cells, a specific type of white blood cell that protects the body from certain threats, including viruses and infections.

How do you strengthen your thymus gland?

Vitamin A supports the thymus and stimulates the immune response. Daily supplementation with high dose vitamin C maintains the size and weight of the thymus and increases the number of T cells. You also need enough selenium for immunity against viruses and cancer.

Diseases & conditions The most common thymus diseases are myasthenia gravis (MG), pure red cell aplasia (PRCA) and hypogammaglobulinemia, according to the NLM. Myasthenia gravis occurs when the thymus is abnormally large and produces antibodies that block or destroy the muscles’ receptor sites.

Can you live without a thymus?

The thymus “trains” cells to become T-cells, white blood cells that fight infection. Since children without a thymus don’t produce T-cells, they’re at great risk for developing infections. Without medical intervention, few children with complete DiGeorge Syndrome live to age 1 and none live past age 3.

Can the thymus grow back?

The thymus undergoes rapid degeneration following a range of toxic insults, and also involutes as part of the aging process, albeit at a faster rate than many other tissues. The thymus is, however, capable of regenerating, restoring its function to a degree.

What happens if the thymus doesn’t shrink?

The thymus is a vital yet unusual organ. Vital in that it is responsible for producing immune cells; unusual in that it is largest at childhood and progressively shrinks after puberty. The result is less T cell production, which should lead to a higher risk of infection or cancer.

What is thymic hyperplasia?

Thymus hyperplasia refers to an enlargement (“hyperplasia”) of the thymus. It is not always a disease state. The size of the thymus usually peaks during adolescence and atrophies in the following decades.

How is thymic hyperplasia treated?

Thymic hyperplasia by itself does not require any treatment, but the associated conditions, such as hyperthyroidism, may. In patients with MG and thymic hyperplasia, we will probably recommend surgery to remove the thymus gland.

How is thymic hyperplasia diagnosed?

Thymic hyperplasia could be true thymic or lymphoid hyperplasia. It is usually found incidentally or could present with compressive symptoms or systemic symptoms due to autoimmune disease like myasthenia gravis. The diagnosis is made through a chest CT or MRI. Treatment for symptomatic patients is mostly thymectomy.

Can thymus be seen on xray?

The thymus usually has smooth borders and remains visible on radiographs through the age of 3 years.
