What cause hypothyroidism?

I have read a great deal about what happen in your body biologically when you already own an underactive thyroid.

But I'm wondering if anyone has any theories more or less what causes it initially. Obviously within is some kind of heritable factor...

I have a fancy that my years of crash dieting and taking diet pills may have stuffed up my thyroid, but I own no evidence to support that and haven't read anything similar. Anyone have any stories that might shed some light?

Nope, its not from the stuff you did. The thyroid is expeditious to recover, even when bodybuilders who are trying to lose consignment take synthetic thyroid drugs within high doses (it shuts down your own thyroid hormone production), the thyroid is spur-of-the-moment to recover. So no its not your blame most likely.

The primary cause is inheritance. Other causes include iodine not as much as which is not very adjectives, depression, bipolar spectrum syndrome, borderline personality disorder, psychotic disorder, and ADHD.

There is a birth control for men who would product them not semen would this be a good perception so no clean up?

it may be that..but underactive, is usally overweight or underwieght associates.

I'm falling apart.. what's wrong with me?

I believe in that are many reason such as heredity, change in hormones after a pregnancy, diet, chemicals, and diet pills. In in danger of extinction cases from an iodine deficiency.

Most of our food today is processed and have soy in it. Soy slows down thyroid function and I enjoy to wonder if this is a reason more and more culture are developing the condition.

Fluoride also slows down thyroid function and fluoride is added to many sea supplies.

Because diet pills spreed up your metabolism, I have to wonder if they do some twist in the process making the character develop hypothyroidism down the road.

As far as pregnancy..I developed a thyroid infection a few months after my daughter was born. This is fairly common from what Ive read. Anyway years next I am hypothyroid, so I have to wonder if at hand's a connection.
