How come an under active thyroid sometimes shows no symptoms?
Because the symptoms are kind of ´common´, they´re not really typical for an under active thyroid, except when you add them together. When you search for a check-list, you can find all kinds of problems that all can be caused by your under active thyroid! But on the other hand, there are a lot of people who have an under active thyroid for years and never notice it. But it’s never good for your body, if the levels are really off, because it can cause lot’s of shitty problems. And, everyone reacts differently on the bloodlevels. It’s what condition you’re whole body is in, your age, fysical and mental condition, etcetera. PS: sorry for any weird grammar or something!
