What is simple diffuse goiter?

A variety of causes can lead to the enlargement of the thyroid gland. Simple diffuse goiter is diagnosed when the only abnormality is thyroid swelling. In these cases, blood tests show normal levels of thyroid hormone and antibodies, and ultrasonography reveals swelling with an absence of inflammation and lumps. What causes the swelling of the entire thyroid gland is unclear, but it appears most commonly during puberty. However, since simple diffuse goiter may be the first step towards thyroid abnormalities, we recommend regular testing and observation of a patient’s condition. In some foreign locations, it may be difficult to get enough iodine from the diet. Looking globally, adding iodine to salt and other measures have reduced this problem in iodine deficient regions. Nevertheless, residing for long periods of time in an iodine deficient region may lead to a diet with insufficient iodine intake. This can affect the swelling of the thyroid gland.

Symptoms

There are no symptoms other than the visually apparent swelling of the thyroid gland.

Examinations and treatments

Ultrasonography (echography) detects the presence of lumps and evaluates thyroid size. Blood tests assess thyroid hormone levels and antibodies. If no abnormalities are detected, then treatment is not needed. However, it is necessary to have regular blood tests and ultrasonography to check for abnormal thyroid function and lumps. These tests can confirm that there are no other thyroid diseases present.
