👉 Sarcocystoid is a medical term used to describe an abnormal enlargement of the thyroid gland. It occurs when the thyroid gland becomes enlarged and can be painful or cause discomfort during certain activities such as lifting heavy objects, standing for long periods, or performing strenuous sports. This condition is often caused by a combination of factors including genetics, hormonal changes, and infections. Treatment may include medications to reduce swelling and pain, surgery to remove excess tissue, or radiation therapy to shrink the thyroid gland.
