How Your Gut Can Help You Balance Your Hormones

The relationship between gut health and hormones is gaining traction and getting some serious attention these days. Recent studies have linked gut health to everything from depression and anxiety to brain fog. The gut, often referred to as the "second brain," is more than just a digestive organ; it plays a pivotal role in maintaining overall health, including hormonal balance. The gut microbiome plays a key role in hormonal regulation and an unhealthy gut can lead to hormonal imbalances that can make you feel seriously off, physically and mentally. 

Understanding the Gut-Hormone Axis

The gut-hormone axis describes the bi-directional communication between the gut and the endocrine system (which is what produces your hormones). These two systems are in constant communication, using a few different pathways: 

1. The Microbiome: Trillions of bacteria, viruses, and fungi inhabit the gut, collectively known as the microbiome. These microorganisms influence the production and regulation of hormones.

2. The Gut-Brain Axis: The gut and brain communicate via the vagus nerve and neurotransmitters, affecting hormonal signals.

3. Hormonal Metabolism: The gut plays a key role in metabolizing, eliminating and recycling hormones, particularly estrogen, through the action of gut bacteria.

Key Hormones Influenced by Gut Health

1. Estrogen:

   • The gut microbiome affects estrogen levels through the estrobolome, a subset of gut bacteria that metabolizes estrogen. Dysbiosis, or an imbalance in gut bacteria, can lead to excess or insufficient estrogen, contributing to conditions like estrogen dominance, which can be characterized by a host of symptoms including hair loss, anxiety and fibroids.

2. Cortisol:

   • Known as the stress hormone, cortisol levels need to stay balanced to keep your energy up but your anxiety down. A healthy gut can modulate stress responses while an unhealthy gut may overload you on cortisol when you get stressed. 

3. Thyroid Hormones:

   • Your gut can have a major impact on your thyroid hormones, primarily by impacting the absorption of essential minerals like iodine, selenium, iron, and zinc, which are crucial for thyroid hormone production. Your gut bacteria can either hinder or improve your uptick of these key nutrients, which will directly impact your thyroid function.

4. Insulin:

   • Gut bacteria interact with dietary components to regulate blood sugar levels. Dysbiosis can lead to insulin resistance, a precursor to conditions like PCOS (polycystic ovary syndrome) and type 2 diabetes.

5. Serotonin:

   • Our “happiness hormone”- it’s recently been discovered that close to 90% of your serotonin is produced in your gut. A balanced microbiome supports optimal serotonin production, which impacts mood, stress resilience, balance and calmness.

How Gut Health Impacts Hormones

The connection between gut health and hormones happens through a few key pathways:

1. Inflammation:

   • Chronic gut inflammation, often caused by poor diet, stress, or infections, can disrupt hormonal signaling. This inflammation affects the hypothalamus-pituitary-adrenal (HPA) axis, which regulates many hormones. Chronic inflammation can also lead to leaky gut syndrome, which is when your gut lining becomes permeable. This allows undigested food particles and toxins to enter the blood stream, which can trigger immune responses and hormonal imbalances.

2. Detoxification and Elimination:

   • The liver and gut work together to detoxify and excrete hormones. A sluggish gut can impair this process, leading to the reabsorption of hormones like estrogen. Remember, the body likes balance, and any time it’s not able to create it, you’ll feel the impacts. 

3. Nutrient Absorption:

   • The gut’s ability to absorb nutrients directly impacts hormone production. For example, magnesium, zinc, and B vitamins are essential for hormone synthesis and regulation- and if you can’t absorb them, your body can’t use them.

Signs of a Gut-Hormone Imbalance

A hormonal imbalance can cause a range of symptoms, from mild to severe. These can often hang around for years, undiagnosed, and irreparable until you identify them and do the work to heal your gut. Symptoms can includeL

• Digestive issues like bloating, constipation, or diarrhea.

• Irregular menstrual cycles or PMS.

• Unexplained weight changes.

• Chronic fatigue or low energy.

• Mood swings, anxiety, brain fog or depression.

• Skin issues such as acne or eczema.

• Hair loss, skin rashes, itchy skin.

How to Support Your Gut:

1. Get Your Fiber In:

   • Include plenty of vegetables, fruits, whole grains, and legumes. Fiber supports healthy digestion and feeds beneficial gut bacteria- you want to aim for 25-30g/ day, but work your way up if you’ve been slacking on fiber. A sudden load can lead to bloating and discomfort- add in about 5g/day for a week, then increase by another 5g/ day the following week, until you’re at 25-30g/ day.

2. Probiotics and Prebiotics:

   • Probiotics (found in fermented foods like yogurt, kefir, and sauerkraut) introduce beneficial bacteria to the gut. Prebiotics (found in foods like garlic, onions, and bananas) provide fuel for these bacteria.

3. Reduce Sugar and Processed Foods:

   • Excess sugar and processed foods can promote harmful bacterial growth and inflammation, disrupting gut health.

4. Relaaaaxxx:

   • Chronic stress can harm the gut microbiome. Practices like meditation, yoga, or deep breathing can help you stay collected.

5. Drink Up:

   • Staying hydrated supports digestion and the elimination of toxins and hormones.

6. Get Moving:

   • Physical activity promotes a healthy microbiome and improves insulin sensitivity.

Special Considerations for Women’s Health

Women experience unique hormonal fluctuations due to menstruation, pregnancy, and menopause. Gut health plays a critical role in managing these changes:

• Menstrual Health:

  • A healthy gut can mitigate PMS symptoms by regulating estrogen levels and reducing inflammation.

• Pregnancy:

  • Gut health influences fertility and the health of both mother and baby. The maternal microbiome affects the baby’s developing immune and hormonal systems.

• Menopause:

  • Supporting gut health during menopause can alleviate symptoms like hot flashes, mood swings, and weight gain by balancing estrogen levels.

• Hormonal Birth Control

  • Hormonal birth control can significantly alter your natural hormonal balance (I mean, that's kind of the point right?) Maintaining a healthy gut and supplementing lost nutrients is key for anyone on hormonal BC, and special care should be taken when coming off hormonal BC to rebalance the body.

The connection between gut health and hormones is a testament to the body’s intricate design. By nurturing your gut, you can positively influence your hormonal balance, overall health, and well-being. Small, consistent changes in diet, lifestyle, and stress management can make a significant difference. Questions? Let me know in the comments.
