A goiter is an enlarged thyroid gland.

The thyroid gland is situated in front of the windpipe and is responsible for producing and secreting hormones that regulate growth and metabolism.

Most cases are categorized as ‘simple’ goiters that do not involve inflammation or any detriment to thyroid function, produce no symptoms, and often have no obvious cause.

Some people experience a small amount of swelling. Others can have considerable swelling that constricts the trachea and causes breathing problems.

Symptoms

The degree of swelling and the severity of symptoms produced by the goiter depends on the individual.

Most goiters produce no symptoms. When symptoms do occur, the following are most common:

throat symptoms of tightness, cough, and hoarseness

trouble swallowing

in severe cases, difficulty breathing, possibly with a high-pitch sound

Other symptoms may be present because of the underlying cause of the goiter, but they are not because of the goiter itself. For example, an overactive thyroid can cause symptoms such as:

nervousness

palpitations

hyperactivity

increased sweating

heat hypersensitivity

fatigue

increased appetite

hair loss

weight loss

In cases where goiter is a result of hypothyroidism, the underactive thyroid can cause symptoms such as:

cold intolerance

constipation

forgetfulness

personality changes

hair loss

weight gain

Aside from the swelling itself, many people with goiter present no symptoms or signs at all.

Causes

Goiter can be caused by a number of different conditions:

Iodine deficiency
