Any regular readers of this blog will know that for a few months now I’ve had some mysterious medical issues that my doctors have been somewhat baffled by. I’ve had blood tests, an MRI of my pituitary, and a scan of my thyroid with radioactive technetium. Despite being told at the hospital that the results of my scans would be available within a couple of days, it took a month before anyone actually got back to me with the results. I tried to take that as a sign that it wasn’t anything incredibly serious, but anyone who’s had extensive dealings with my hospital’s admin systems would know that you wouldn’t want to stake anything particularly important on their effective functioning (like, say, your long term health…)
Anyway, I finally heard from a doctor, and he confirmed that they believe I have a condition called post-partum thyroiditis. Even though I already have a pre-existing thyroid condition, I’d never heard of this quite common post-pregnancy thyroid illness. So what is post-partum thyroiditis?
What is post-partum thyroiditis?
Long story short, this is caused by your thyroid gland going a bit haywire due to a rebounding immune system after pregnancy. It typically starts with having thyroid hormones that are too high (hyperthyroidism) for a few months. Then it either just returns to normal, or the thyroid hormones dip too low (hypothyroidism) for a few months – or even permanently.
How would I know if I have it?
Post-partum thyroiditis is actually quite a common condition with around 5 – 10% of women experiencing it, although a lot of the time the symptoms are just ascribed to normal post-pregnancy recovery. Most women initially experience hyperthyroidism – symptoms can include a racing heartrate, anxiety, tiredness, difficulty sleeping, achey muscles, twitching or shaking, feeling hot or sweating a lot, and weight loss. Obviously most of those could easily be ascribed to the post-birth recovery period and/or sleep loss thanks to your new baby.
The only way to know for sure if you have post-partum thyroiditis is to have blood tests to check your thyroid hormone levels. So if you’re concerned that you may have this condition, please make sure you speak to your doctor about it.
How is post-partum thyroiditis treated?
Hyperthyroidism as a result of post-partum thyroiditis (let’s just call it PPT) is not usually treated beyond beta blockers to reduce the impact of the symptoms of fast heartrate, anxiety, etc. Conveniently, I’m already taking beta blockers as my doctors tend to prescribe them at the first sign of hyperthyroidism, as my heart loves to go too fast and will take literally any excuse to do so.
Hypothyroidism might need to be treated with replacement thyroid hormone if it becomes severe enough. I’m hoping we don’t have to go there.
How long does postpartum thyroiditis last?
How long is a piece of string? Unfortunately, it seems that postpartum thyroiditis is a very variable condition and each woman has a different experience, so there’s no way of saying how long my postpartum thyroiditis will last. It could be a few months, a year, or even longer – sometimes the side effects are permanent.
What are the risk factors for postpartum thyroiditis?
The big question for me was whether my existing pituitary condition (which affects my thyroid) creates a risk factor for postpartum thyroiditis. A quick Google indicates that I’m not the only person with a TSHoma to go on to develop post-partum thyroiditis. But because my pituitary tumour is so rare, when anything out of the ordinary happens the doctors don’t really know what to expect. However, previous history of thyroid issues is a known risk factor for post-partum thyroiditis, as is a history of auto-immune illness.
What are the implications for me personally?
It’s just a case of wait and see, and hope I don’t end up with low thyroid levels, as that could make things complicated in terms of treating it and my pituitary tumour. So please keep your fingers crossed for me!
In the meantime, I’m back to monthly blood tests to monitor my thyroid level and regularly checking in with the hospital.
Are you a postpartum thyroiditis patient in the UK? I’d love to hear about your experience! Let me know in the comments.
