How Your Gut Health Impacts Hormonal Balance (and What You Can Do About It)

When you think of hormones, you probably think of hot flashes, mood swings, or perhaps the struggle to lose weight as we age. But did you know that your gut plays a vital role in balancing those hormones? For women over 40, gut health becomes more important than ever in the quest to maintain hormonal harmony.

​Let’s dive into why your gut is so essential for keeping your hormones in check and the steps you can take to start improving your gut health today.

What’s the Connection Between Gut Health and Hormones?

You’ve likely heard the phrase, “You are what you eat,” but when it comes to hormones, it’s more accurate to say, “You are what your gut absorbs.” Your digestive system does more than just break down food — it also plays a crucial role in hormone regulation.

Here’s the breakdown:
​

• Gut Microbiome: The trillions of bacteria and microbes in your gut make up your microbiome, which impacts everything from digestion to mood. A healthy balance of gut bacteria supports the production and regulation of essential hormones, including estrogen, progesterone, and cortisol.

 

• Estrobolome: A specific part of your gut microbiome, called the estrobolome, is responsible for metabolizing estrogen. If your gut health is compromised, it can lead to an imbalance in estrogen levels, which can trigger symptoms like weight gain, mood swings, and increased PMS.

 

• Inflammation: Poor gut health can lead to inflammation throughout your body. Chronic inflammation disrupts hormone balance and can worsen symptoms of menopause, perimenopause, and thyroid conditions.

So, if you’re feeling bloated, moody, or noticing that stubborn belly fat just won’t budge, your gut might be the hidden culprit.

How Gut Health Changes After Age 40

As we age, both our gut health and hormonal balance become more delicate. Several changes occur after age 40 that make it harder to maintain the gut-hormone connection:
​

• Slower Metabolism: Your digestive system slows down, which can affect how efficiently your gut absorbs nutrients and how well it manages hormones.

• Reduced Estrogen: As estrogen levels drop during perimenopause and menopause, it can throw off your gut microbiome, leading to digestive discomfort and exacerbating hormonal imbalances.

• Increased Stress: Let’s face it—by the time you hit midlife, the demands of career, family, and health can take their toll. High stress affects gut health by promoting inflammation and can mess with cortisol, the stress hormone.

• Digestive Enzyme Production: Your body produces fewer digestive enzymes as you age, making it harder to break down and absorb essential nutrients. This contributes to bloating, gas, and indigestion, which can further interfere with hormone health.

Common Gut Health and Hormonal Imbalance Concerns of Women 40+ 

If you’re over 40 and struggling with gut and hormone-related symptoms, you’re not alone.

Here are five of the most common concerns and questions I hear from the women I help in my coaching programs:

1.  “I can’t lose weight, even when I eat clean and exercise!”

If weight loss feels impossible despite your best efforts, the issue is likely not a lack of willpower — it could be hormonal imbalance related to your gut health. Gut bacteria can influence how your body stores fat and responds to insulin, which directly impacts weight.
​
2.  "I’m constantly bloated and uncomfortable.”

Bloating can stem from poor digestion, an imbalance in gut bacteria, or inflammation. All of these factors contribute to hormonal imbalances, making it harder for your body to regulate hormones like estrogen and progesterone.

3.  “Why am I so tired all the time?”

Fatigue, especially for women in midlife, is often linked to both poor gut health and hormonal imbalance. When your gut isn’t absorbing nutrients effectively, it impacts your energy levels. In addition, fluctuating hormones can lead to disrupted sleep and feelings of burnout.

4.  “My mood swings and irritability are out of control!”

Your gut and brain are intimately connected through the gut-brain axis. An unhealthy gut can lead to imbalanced production of serotonin, a neurotransmitter that affects mood, while unstable estrogen and cortisol levels can intensify mood swings.

5.  “I’m having trouble with digestion — gas, constipation, and diarrhea are part of my daily life now.”

​Digestive issues like gas, constipation, or diarrhea often become more common with age. These symptoms indicate that your gut microbiome may be out of balance, which in turn can disrupt your hormone levels.

What You Can Do to Improve Your Gut Health (and Balance Your Hormones)

Now that we’ve covered how gut health impacts your hormones, let’s talk solutions. The good news is that improving your gut health is entirely possible, and it can bring much-needed balance to your hormones.

Here are some simple, actionable steps you can start implementing today.

1.  Eat Fiber-Rich Foods

Fiber is essential for healthy digestion and hormone balance. Foods high in fiber support the growth of beneficial bacteria in the gut and aid in the detoxification of excess hormones like estrogen.

• Foods to try: Leafy greens, berries, flaxseeds, chia seeds, quinoa, and cruciferous vegetables.
• Pro tip: Aim for at least 25 grams of fiber per day.

2.  Incorporate Probiotics and Prebiotics

Probiotics are the good bacteria that help keep your gut microbiome balanced, while prebiotics act as food for these bacteria. Together, they can support hormone regulation by promoting a healthy gut environment.
​

• Probiotic foods: Yogurt, kefir, sauerkraut, miso, and kimchi.
• Prebiotic foods: Garlic, onions, asparagus, and bananas.
• Pro tip: Consider a high-quality probiotic supplement if you're not getting enough from food.

3.  Manage Stress

We’ve all heard that stress is bad for our health, but when it comes to your gut and hormones, it’s especially harmful. Chronic stress leads to inflammation and can weaken your gut lining, creating a vicious cycle that worsens hormonal imbalance.

• Stress management tips: Try yoga, meditation, deep breathing exercises, or even just taking time out for yourself daily.
• Pro tip: Make stress reduction a non-negotiable part of your routine.

4.  Stay Hydrated

Water is essential for digestion and helps move waste, including excess hormones, out of your body. Dehydration can lead to sluggish digestion, which can cause hormone imbalances to worsen.

• Pro tip: Drink at least 8-10 cups of water daily. Try adding a squeeze of fresh lemon juice for extra detox benefits.

5.  Limit Added Sugar and Ultra-Processed Foods

Too much refined sugar and ultra-processed foods can trigger inflammation in the gut, disrupt your gut bacteria, and lead to blood sugar imbalances, which directly impact your hormones.

• Pro tip: Swap sugary snacks for whole foods like Greek yogurt with berries or veggies with hummus.

6.  Get Moving

Exercise supports gut health by promoting a healthy microbiome and improving digestion. It also helps balance hormones like insulin, cortisol, and estrogen, which are all crucial for maintaining a healthy weight and mood.
​

• Pro tip: Aim for at least 30 minutes of movement each day. This can be a brisk walk, yoga, strength training, or dancing!

7.  Prioritize Sleep

Sleep is essential for both gut health and hormonal balance. During sleep, your body repairs itself, regulates cortisol, and supports the gut microbiome. Poor sleep leads to hormonal chaos, and that can throw your digestion out of whack, too.
​

• Pro tip: Aim for 7-9 hours of sleep each night and create a calming bedtime routine.

Final Thoughts:  Small Changes Make Big Differences

Gut health and hormone balance go hand in hand, especially for women over 40. If you’ve been experiencing weight gain, mood swings, fatigue, or digestive issues, your gut might need some extra love. Start with small, consistent changes like eating more fiber, managing stress, and incorporating probiotics into your diet.

Taking care of your gut is one of the most powerful steps you can take to regain hormonal balance and feel your best in midlife. You don’t need to overhaul your entire life — just a few key habits can make a world of difference.
