If your thyroid hormone levels are not normal, you could experience a myriad of symptoms such as fatigue, racing heart, and inability to control your body temperature, among others.
If you are feeling out of sorts, fatigued, anxious for no reason, are inexplicably losing or gaining weight, are having trouble sleeping, are sensitive to the heat or cold, experiencing changes in your menstrual cycle or voice, or have vision and hair problems, you may need to have a blood test for thyroid.
