Absolutely ! Im going for a full thyroid panel tomorrow as a matter of fact. It can also cause you to miss taking that deep breath ie: irregular breathing, google "Hypothyroid and deep breath" I was amazed and hopeful, I have about ten symptoms of "hypo" Anxiety, depression, irritability, fatigue, dry skin, constipation, tingling and numbness in hands and feet, irregualr breathing, sensitivity to temperature (never had it before, now I cant take cold, im always cold now)....
