How Caitlin Richards discovered she had thyroid issues, and how you can too.

For a relatively tiny part of the body, the thyroid can have a significant health impact.

The butterfly-shaped gland sits at the front of the throat and secretes hormones that play a key role in regulating numerous metabolic processes, including heart rate, weight and body temperature. If a thyroid stops functioning properly it can result in health issues, sometimes serious ones.

In 2004, Caitlin Richards (pictured above, left) had been experiencing bouts of fatigue and fainting, so she booked an appointment with her GP to find out why. One possible cause was immediately evident to her doctor.

“She said, ‘Are you aware you have a goitre?’ I was like, ‘Uh, nope’,” Caitlin recalls.

An ultrasound and blood tests revealed the then-13-year-old had hypothyroidism, or an underactive thyroid. It had been “overworking” to produce the hormone Thyroxine, but hadn’t been successful, thus causing the gland to swell up considerably.

Hypothyroidism is the most common thyroid problem; research from MedicalDirector's General Practice Research Network suggests it accounts for 70 per cent of thyroid condition medical visits. Interestingly, these conditions affect women more frequently than men.

"For people with hypothyroidism, their low Thyroxine level will make them sluggish and tired most of the time," explains MedicalDirector chief medical officer Dr Andrew Magennis.

"This can be compared with those who have hyperthyroidism, where people can’t sleep and feel constantly agitated or anxious."

Caitlin was initially diagnosed with Hashimoto's disease, an autoimmune condition that commonly causes hypothyroidism.

She began taking daily hormone tablets and was monitored by an endocrinologist every six months, to have her levels checked and medication adjusted accordingly.

Caitlin says her age made it hard to tell whether the condition produced any symptoms — she remembers being "quite tired" at the time, but points out this isn't uncommon for a teenager so she didn't think much of it.

"I also wasn't overweight, which was unusual because usually with an underactive thyroid you can put on weight. That's never been an area of concern for me," Caitlin, now 26, adds.

Although her Hashimoto's diagnosis changed, she remained on medication for her underactive thyroid until two years ago.

Caitlin made an appointment with her endocrinologist and explained she hadn't been consistent with her medication, but didn't feel as though that had affected her negatively.

After trialling a couple of medication-free months, a blood test revealed Caitlin's thyroid had returned to normal function. However, she was told there will always be a risk it could become underactive again due to anti-thyroid autoantibodies, which can stop the gland working properly.

"I'll always have those particular enzymes in my body, but for some reason they've stopped attacking my thyroid at this moment," she explains.

Caitlin now has yearly blood tests to monitor her thyroid function, and is keenly aware of the symptoms to be on the lookout for, which include depression, weight fluctuations and fatigue. She also still has a goitre; these will sometimes go down when medicated, but that's not always the case.

"There's a lot of thyroid issues with having children and pregnancy, so I'll have to get that all checked out and possibly go back to medication when I get to that stage," she adds.

Health problems arising from thyroid function accounted for more than half a million GP visits in Australia last year, so they're not exactly rare — but a lack of awareness around the issue remains.

This is why Caitlin is sharing her story, as part of Thyroid Awareness Month. Her experience doesn't necessarily reflect that of others — there are several different health issues and conditions tied to the thyroid, and many people will continue treatment for their whole lives.

From her own personal experience, Caitlin stresses the importance of getting checked out my a doctor and seeking treatment for thyroid conditions, as they can have serious long-term health consequences if left untreated.

For her, getting onto the symptoms early and having "a good endocrinologist" to monitor her treatment made managing the condition easier.

"It can be hard to detect [thyroid issues]," the speech pathologist adds.

"A lot of the symptoms can be put down to other stuff ... I think a lot of people would brush off the symptoms as part of day-to-day tiredness or weight changes."
