If hypothyroidism goes untreated, can i still have kids?

I was diagnosed with Hypothyroidism (under-active thyroid) at birth and was told that if i didnt take my pills everyday then i could get brain damage but when i was 16yrs old i stopped taking my pills as they were making me feel tired all the time and since then i've felt ok, a bit of thinning in my hair but other than that ok. I'm 19 now and read that Hypothyroidism, if untreated can deny me having any children in the future.
Is this true? Can you help?

Low thyroid levels in kids do cause lower IQs, since there are not enough hormones to supply the fast metabolic needs of brain cells. That is why your doctor told you that. That will also be an issue for your child if you are still hypothyroid, since the child relies on its mom for thyroid hormone while a fetus.

There is also a higher incidence of infertility and miscarriages in someone with low thyroid. This is something to consider if you do have a thyroid problem going untreated.

By a thyroid problem going untreated, I mean that you are doing nothing for it. Sometimes medication is necessary, but a lot of the times you can do things naturally to resolve the problem.

If you've been ok while off your meds, then you most likely can handle this problem without it.

I have a blog with more information on this.

there is a risk

thyroid hormones are important for regulating metabolism and the pituitary- ovarian axis hormone balance ,if u dont take them u could be infertile ,its essential ,,hope this well help u out

I have never heard that A) not taking your thyroid pills will give you brain damage, or B) you can't have children if you're hypothyroid and untreated. Where did you hear this from? Consider your source.
I am hypothyroid myself (though not since birth) and I take my pills daily. I am also sleepy all the time, but I don't think that's because of the pills (the exact opposite--insomnia--is a common side effect of levothyroxine). What I'm getting at is, I don't think you should have stopped taking your pills, without asking a doctor first. That's pretty scary.

It has been 3 years since you stopped taking thyroid hormone. I think you should go for a thyroid profile that will decide if you are euthyroid. In that case you won't need to take the pills.This is more important than thinking about having kids. If you are hypothyroid you must take pills as advised by your doctor. It becomes even more important when you decide to have kids.
Good luck!

We cannot help you. Who can? Your physician.

See your physician for a TSH (thyroid-stimulating hormone) test or a full thyroid panel. You may no longer be hypothyroidic. Anyone taking thyroid hormone replacement should be a yearly TSH. In some cases, a thyroid can "start working again" and the person may become hyperthyroidic, a very dangerous condition.

Untreated hypothyroidism can, at worst, be fatal. So can hyperthyrodism.

please, and i urge you to have that treated. that is very important. the pills are fairly inexpensive. the last thing you need is thyroid cancer.

Yes, definitely hypothroidism if not treated proves to be an obstacle for conception, but it neednt be the only cause. There can be many more like obesity, sugar, etc.
Also once detected it is, in most of the cases, a lifetime ailment and has to be treated by the day. I have hypothroidism and it keeps fluctuating depending on the body weight.
Since the metabolic rate is low in such cases people tend to put on weight.
It would be advisable to not to neglect the medicines but to do a regular blood-test for this so as to keep the hormone functioning effectively. Dont be your own doctor, atleast in this case.
