Sarah was used to dealing with minor health issues. She’d gained a bit of weight in recent years and figured the occasional muscle and joint pain she felt was somehow related. She grew familiar with constant, nagging fatigue. She’d always assumed it came from the minor depression that seemed to run in her family. She didn’t realize anything was really wrong until she received word after her yearly physical that her cholesterol levels were off balance. Sarah’s doctor ran more tests over the following weeks and they discovered that all of her symptoms were indeed related—to hypothyroidism.
