Can Thyroid Problems Cause Dizziness?

Yes, thyroid problems can cause dizziness through multiple pathways. Both hyperthyroidism and hypothyroidism may be associated with dizziness, although dizziness has many possible causes and is not specific to thyroid disease. Hyperthyroidism can increase heart rate and cause palpitations or an abnormal rhythm, which may contribute to lightheadedness in some people. Researchers have reported associations between thyroid disorders and some balance or inner-ear conditions, but it is not clear that thyroid disease directly causes these problems. Hypothyroidism may contribute to nonspecific lightheadedness or unsteadiness in some people. If dizziness persists or occurs with weight changes, fatigue, or heart palpitations, talk with a healthcare professional. They can assess its many possible causes and decide whether thyroid testing is appropriate. Seek urgent care for sudden severe dizziness or dizziness with fainting, chest pain, trouble speaking, weakness, a severe headache, or difficulty walking.
