If your cycle feels irregular, your PMS has gotten worse, or you’re dealing with unexplained thyroid symptoms—Candida overgrowth could be playing a bigger role than you realise.
While Candida is often associated with digestive or skin symptoms, it also has a surprisingly deep connection to your hormonal health. In this article, we’ll explore how Candida can influence your cycle, mood, and thyroid function—and what you can do about it.
Candida albicans is a type of yeast naturally found in the gut, mouth, and vaginal tract. In healthy levels, it’s harmless. But when it overgrows—often due to antibiotics, poor diet, high stress, or birth control use—it can create systemic issues.
Your gut and hormones are deeply interconnected. When the gut is inflamed or imbalanced, it can affect how your body produces, processes, and eliminates hormones like oestrogen, progesterone, and thyroid hormones.
Candida can influence the balance of oestrogen and progesterone in a few sneaky ways:
Your body gets rid of excess oestrogen through the liver and bowel. But Candida overgrowth can:
This can result in oestrogen dominance, where your body has more oestrogen than progesterone. Symptoms might include:
High stress, poor gut health, and inflammation can reduce progesterone levels. This leads to:
Progesterone is the calming, balancing hormone. If it’s low and oestrogen is high, your cycle can feel like a rollercoaster.
The thyroid gland is highly sensitive to gut health—and Candida overgrowth can trigger thyroid dysfunction in a few ways:
Candida can damage the gut lining, contributing to leaky gut. This may allow food proteins and toxins to enter the bloodstream, triggering immune responses that target the thyroid—especially in people genetically predisposed to autoimmune conditions like Hashimoto’s.
Symptoms include:
Thyroid health depends on nutrients like selenium, zinc, iron, and iodine. If Candida is disrupting your gut lining, you may not absorb these nutrients well—leading to sluggish thyroid function even if your labs are “normal.”
Candida overgrowth can increase inflammation and stress hormones like cortisol, which further disrupts the thyroid by slowing down T4-to-T3 conversion.
If you’re experiencing any of the following symptoms, Candida could be a contributing factor:
If you suspect Candida is affecting your hormones, here are a few places to start:
Your liver plays a key role in hormone metabolism and Candida detox. Support it with:
Use an app or journal to track your symptoms and period patterns. This helps you notice patterns and changes once you begin supporting your gut and hormones.
If symptoms persist, work with a practitioner to explore:
Your hormones and gut are in constant conversation—and when Candida overgrowth throws your microbiome out of balance, it can lead to a cascade of hormonal issues. By supporting your gut, liver, and stress levels, you’ll be supporting your hormones too.
You don’t need to suffer through unpredictable cycles, fatigue, or thyroid confusion. Tune into your body, support the root causes, and take healing one step at a time.
