Complications

Small goiters that don't cause physical or cosmetic problems aren't a concern. But large goiters can make it hard to breathe or swallow and can cause a cough and hoarseness.

Goiters that result from other conditions, such as hypothyroidism or hyperthyroidism, may be associated with a number of symptoms, ranging from fatigue and weight gain to unintended weight loss, irritability and trouble sleeping.
