Migraine Linked to Thyroid Problems
People who have migraines or other headache disorders may also have a higher risk for hypothyroidism—a condition in which the thyroid gland does not produce enough thyroid hormone. Hypothyroidism—which, like migraine is more common in women than men—can cause mood swings, weight gain, hair loss, fatigue, and other symptoms.
For the study, 8,400 people were followed for 20 years. Results show that people with headache disorders like tension or cluster headaches were 21 percent more likely to develop hypothyroidism and people with migraines had a 41 percent higher risk.
The link is not clear at this time, and the study did not prove that one condition causes the other. Neither migraines nor hypothyroidism are usually life-threatening, but both conditions can impact quality of life. According to researchers, people with headache disorders should be tested for hypothyroidism.
