I went to the doctor on the advice of some people that work closely with me and found out that I was suffering from thyroid problems as well as low testosterone problems.

I think people assume that having thyroid disease means you're older and overweight, but in reality, thyroid disease strikes at all ages and affects all sizes.

After the 2012 Olympics, I returned to training, but unlike in previous years, my off-season weight gain didn't melt off as soon as I got back to my routine. I was tired, and my clothes weren't fitting. I'd been diagnosed with hypothyroidism, which means my thyroid is underactive, and that slows my metabolism.

I really discovered I had thyroid disease by accident. My son was having some health concerns, and as I filled out his patient history I noticed I had a lot of similar symptoms. I mentioned it to the doctor, and he ran blood work and finally an ultrasound of my thyroid.

When I hit 40, I ballooned. I thought it might have been age, abuse, but it wasn't, it was a thyroid condition.

While receiving radiation treatment for a thyroid illness, I had refused to take beta-blockers - a medication that would have eased its side effects - because they were deemed illegal by the sport's governing body, the International Association of Athletics Federations.

I had major thyroid issues, so your fertility count does go down.

Learning that whole grains, legumes, fruits and vegetables can help prevent many cancers, including cancers of the prostate, breast, mouth, throat, esophagus, lung, colon, kidney, pancreas, thyroid, gallbladder, and probably other cancer types is a powerful lesson that can have a significant impact on children's lives.

I bike ride and swim but I don't exercise 'cos I like it. I do it because I've got a thyroid problem that can balloon my weight up to 20 stone if I stand still for five minutes.

I have autoimmune disease, thyroid problems, and I've been diagnosed pre-diabetic.

I just think the whole kale thing has gone a little overboard. It's everywhere you go, and it can actually inhibit thyroid function.

Having thyroid cancer in 2009 really didn't change my life at all. I wish I could say that I had this epiphany. But I knew I was lucky before that, so it's not like I suddenly realised how lucky I am.

When my friends have a health concern, they call me. I've always been a vitamin taker. I also take digestive enzymes and antioxidants, and supplements that help with the thyroid and adrenals for my time-zone changes.

The thyroid cells take up iodine with particular avidity and are able to store it up in great quantities.

Teaches of Peaches' was a really heavy breakup album - I've actually never told anybody about this, but right before that album, I found out I had thyroid cancer.

I don't have a thyroid anymore. I had radioactive iodine treatment, which destroyed my thyroid. I take medication every day.

I want people to know that blood tests alone won't always detect thyroid disease. My blood panels were normal. I think a lot more people have this disease than are diagnosed.

I have to be cautious, have my thyroid levels checked, and as long as I do that, I'm fine.

If I make 140, I sacrifice a lot of things in my life: my diet, my training, my thyroid. It's insane to make 140.
