Similar to the warning signs of hypothyroidism, the symptoms of hyperthyroidism can become worse or more persistent over timeābut both conditions are highly treatable with prescription meds. If you have a family history of thyroid problems, you are at a higher risk of having a thyroid condition yourself. You may not always be aware of thyroid problems in your family so if you are feeling fatigue, gaining weight, irritability and heat or cold intolerance talk with a physician and see if treatment is right for you.
