10. Family History
If you have a family history of troublesome glands or “goiter” you may expect thyroid problems down the road. The disease is believed to have a strong genetic component, and you should be particularly vigilant if you have a close female relative who develops an overactive or underactive thyroid condition.
Additional risk factors include a family history of autoimmune disorders, as well as age and gender. Women have thyroid problems more often than men, and the majority of cases appear in patients who are over 50 years of age. Thyroid disease is yet another reason you should butt out, as research has found that smokers of both genders are at increased risk.
