When it comes to our hormonal health, one of the most vital signs is something many of us overlook—our poop. The frequency, shape, color, and texture of your stools can reveal important clues about how well your digestion and hormones are functioning. For women, this especially important as hormone balance is directly connected to gut health.
How Digestion and Your Hormonal Health are Connected
Your digestive system is more than just a way to process food. It’s home to the gut microbiome, which plays a significant role in regulating hormones, mood, and immune function. Your gut and hormones are in constant communication, so if one is off, the other is likely affected too.
For instance, digestive issues such as bloating, constipation, or diarrhea can often be linked to hormonal imbalances, including estrogen dominance, thyroid dysfunction, or stress hormones like cortisol. These problems are often worse during different phases of your menstrual cycle, pregnancy, or menopause, when hormonal fluctuations happen the most.
What Your Poop Say About Your Health
Let’s break down the different shapes, colors, and forms of poop and what it might be telling you about your digestive and hormonal health.
1. Shape and Consistency
According to the Bristol Stool Chart (see above), healthy bowel movements are often categorized as Type 3 or Type 4, which are sausage-shaped and smooth. Here’s a breakdown of what different types mean:
• Type 1-2 (Hard, lumpy stools): Think rabbit turds. This often points to constipation, which can be linked to low progesterone levels, especially in the luteal phase of the menstrual cycle or during perimenopause. It may also indicate dehydration or a lack of fiber (vegetables), both of which can stress the adrenals and disrupt your hormone balance.
• Type 3-4 (Smooth, sausage-shaped): This is the ideal form. When your bowel movements look like this, it’s a good indicator that you’re getting enough water, fiber (vegetables), and your hormones are in a balanced state.
• Type 5-7 (Loose or watery): Diarrhea can be a sign of gut inflammation or sensitivity to foods that you are eating. In hormonal terms, loose stools may indicate elevated stress hormones (cortisol) or high estrogen levels. It’s also common around menstruation, when prostaglandins spike, causing muscle contractions that can speed up digestion.
2. Color
While most bowel movements should be a medium to dark brown, there are times when they might change color. Here’s what different shades can tell you:
• Brown: This is considered normal and healthy, showing that your bile production is functioning well.
• Green: If you notice green stools, it could mean your food is moving too quickly through your digestive tract, often due to diarrhea. It may also suggest a diet high in leafy greens or a sign that your body is detoxifying excess estrogen. This could also be a bacterial infection.
• Yellow or pale: This might indicate a lack of bile, which could point to issues with your liver or gallbladder. Estrogen dominance can slow down bile production, leading to pale stools.
• Black or dark red: These can be signs of gastrointestinal bleeding and should be checked by a healthcare professional right away. However, some foods, like beets or iron supplements, can also cause dark-colored stools temporarily.
3. Frequency
How often you go is another crucial indicator. The ideal frequency is once or twice a day, but everyone’s “normal” can differ slightly. Here’s what irregular patterns could indicate:
• Less than once a day (Constipation): Hormonal imbalances like low thyroid function (hypothyroidism) and high cortisol from chronic stress can slow down your digestion. Low estrogen and progesterone in the luteal phase can contribute to sluggish bowel movements. Nutrient deficiencies can also cause slower bowel movements.
• More than three times a day (Diarrhea): Loose, frequent stools may be a sign of stress, food sensitivities, or elevated prostaglandins during your period. Excessive caffeine or an imbalance in gut bacteria (dysbiosis) can also lead to diarrhea.
The Hormone-Digestion Connection
Imbalances in your hormones can directly affect your digestion. Here are some key hormonal players:
• Estrogen: High levels of estrogen, often seen in estrogen dominance, can slow bile production, leading to constipation or pale stools. Low estrogen, on the other hand, can result in looser stools and more frequent bowel movements.
• Progesterone: This calming hormone relaxes muscles, including those in your digestive tract. When progesterone is low, especially during menopause or premenstrually, it can lead to constipation.
• Cortisol: Chronic stress raises cortisol, which can cause gut inflammation and disrupt your bowel habits, leading to either diarrhea or constipation depending on the individual.
• Thyroid Hormones: Hypothyroidism (low thyroid function) is a common cause of constipation, as it slows down every process in your body, including digestion. On the flip side, hyperthyroidism can result in diarrhea due to an overactive metabolism.
Supporting Your Digestion and Hormones
If you notice your digestion isn’t where it should be, consider how your lifestyle and diet may be affecting your hormones. Here are some tips to support both:
• Eat fiber-rich foods: Aim for a variety of vegetables, fruits, and ancient grains to support healthy bowel movements and hormone detoxification.
• Hydrate: Drinking plenty of water can keep things moving and prevent constipation. Aim for at least 1/2 your body weight in ounces of water/day.
• Manage stress: Incorporating stress-management techniques like yoga or meditation can help lower cortisol and improve digestion. Also, testing your cortisol levels with a Functional Medicine Provider can help you understand how to best support them.
• Eat healthy fats: Fat and cholesterol are essential for hormone production and can help ease constipation by supporting bile production.
• Cycle-sync your diet: Tailoring your foods to your menstrual cycle phases can help regulate hormones and improve digestion over time.
Final Thoughts
Your digestion offers a wealth of information about how your body is functioning, especially when it comes to hormones. By paying attention to the shape, color, and frequency of your bowel movements, you can get a clear snapshot of how well your digestive and hormonal systems are working together. If something seems off, it may be time to investigate further with a functional medicine practitioner or hormone specialist to get to the root cause.
Healthy digestion is a cornerstone of balanced hormones, and both are key to understanding what is happening inside your body. Listen to your body, and it will tell you what it needs!
