Sandra Sharpe is a Certified Functional Medicine Health Coach who focuses on the gut and hormone connection and helps women restore hormone balance through a root cause approach. Through her health obstacles with gut and hormonal imbalances, debilitating PMS, chronic migraines, Hashimoto’s Thyroiditis, hypothyroidism, and thyroid cancer, Sandra realized that there were massive gaps in the women’s health space. After years of educating herself about these topics and getting the answers she needed, her mission is to help women worldwide finally get the education, support, and tools they’ve always needed.

In this episode, we talk about why women need to be proactive about our thyroid health, how the thyroid connects with almost every period-related problem and impacts fertility, symptoms of thyroid imbalance, what you need to know about thyroid testing, how you can start to improve your thyroid health without being overwhelmed, and so much more!

This episode is brought to you by Knix, makers of comfortable, period-proof underwear.

I’ve been using period underwear since 2014, long before it was popular, so I know a thing or two about what to look for in a great pair of period undies. I recently started using Knix period underwear, and I’m actually in love. When wearing these undies, you can be fully confident that you won’t have any leaks, even when sitting or lying down for a long time.

Their cotton, leakproof underwear is soft, stretchy, and feels like regular underwear. They come in a range of absorbencies and can absorb up to eight tampons worth of liquid, so they’re great for every day of your period. Not only are they super absorbent, but they also stay dry. Plus, they’re so easy to wash you can just pop them into the washing machine with a mild detergent and tumble dry them on low.

If you’re ready for comfortable, leakproof period underwear, head to Knix.com!

Frequently Asked Questions

Common questions from this episode — and how Fix Your Period can help.

How does the thyroid affect the menstrual cycle?
The thyroid regulates metabolism, energy production, and hormonal balance. Low thyroid function (hypothyroidism) can cause heavy, prolonged, or irregular periods, while hyperthyroidism often leads to light, infrequent periods. The thyroid also directly affects sex hormone binding globulin, which influences how estrogen and testosterone circulate in the body.
What is the connection between Hashimoto's and hormonal health?
Hashimoto's thyroiditis is an autoimmune condition and the most common cause of hypothyroidism. Because it involves chronic immune activation and inflammation, it affects gut health, adrenal function, and hormone production — all of which have downstream effects on the menstrual cycle.
What nutrients support thyroid health?
Key nutrients for thyroid function include iodine, selenium (critical for T4-to-T3 conversion), zinc, iron, and B vitamins. Gut health is also critical — approximately 20% of T4-to-T3 conversion happens in the gut, making microbiome support important for anyone with thyroid dysfunction.
Is there an app to help women with thyroid and period issues?
Yes. Fix Your Period helps you track the cycle and symptom patterns most associated with thyroid dysfunction. Fix Your Period Premium unlocks Nicole's thyroid-supportive protocols, Period Pillars education, and Nicole.AI for personalised guidance.
Do I still need to work with a doctor for thyroid issues?
Yes. Thyroid conditions require proper testing and, in many cases, medication. Fix Your Period works best as a complement to your medical care — supporting the lifestyle and nutritional foundations that allow your thyroid treatment to work most effectively.
