1. Skin Issues
What’s Happening in Your Gut
Skin issues like acne, eczema, and rosacea aren’t just about what’s happening on the surface; they can actually signal problems deeper inside your body, particularly with your gut. These skin problems are often signs of poor gut health.
There’s a strong link between gut health and your skin. Research shows that when your gut flora is out of balance or there’s inflammation, symptoms of bad gut health can manifest as skin problems. For example, acne might be tied to too much inflammation and hormonal changes influenced by your gut, while eczema and rosacea are often connected to food sensitivities and leaky gut syndrome.
What You Can Do
Diet
To support your skin, include more probiotics and anti-inflammatory foods in your meals. Eating a variety of fruits, vegetables, and healthy fats like avocados, nuts, and olive oil can improve skin conditions related to gut issues. It’s also helpful to avoid potential triggers such as gluten or dairy.
Supplements
Adding probiotic supplements can help balance gut bacteria. Omega-3 fatty acids, L-glutamine,, and collagen may also support gut health and reduce inflammation, which can benefit your skin.
Lifestyle
Use gentle, non-comedogenic skincare products to avoid clogging your pores. Opt for products with soothing ingredients like niacinamide and hyaluronic acid to repair and calm your skin. Steer clear of harsh scrubs and products with artificial fragrances to prevent irritation.

Mary’s Cystic Acne Breakthrough
Mary came to me after years of battling stubborn cystic acne that seemed resistant to every treatment she tried. Despite using various skincare products and seeing numerous specialists, she couldn’t find relief.
I recommended food sensitivity testing, which uncovered surprising triggers like coffee, vanilla, almonds, cucumber, mushrooms, watermelon, and raspberries—foods she never imagined could affect her skin.
Mary was shocked to find that even small amounts of these foods would cause painful cysts, a connection she had suspected but never confirmed. Both her dermatologist and aesthetician were amazed by the results.
With this new understanding, Mary was able to manage her acne naturally without relying on medications, and she also noticed improvements in her digestive symptoms. It was a life-changing revelation for her, allowing her to enjoy clear skin and newfound confidence!
2. Bad Breath
What’s Happening in Your Gut
Chronic bad breath, or halitosis, isn’t just about poor oral hygiene; it can be a sign of gut issues or imbalances in gut bacteria. Certain gastrointestinal conditions can lead to bad breath; for instance, an infection with Helicobacter pylori (H. pylori) can create sulfur compounds that cause it. Acid reflux from gastroesophageal reflux disease (GERD) can also make bad breath worse.
Another contributor to bad breath is low saliva production, which can occur due to conditions like Sjögren’s syndrome. Additionally, bad breath often originates from the oral microbiome—the community of bacteria in your mouth. Poor oral hygiene, tooth and gum infections, or imbalances in oral bacteria can lead to the production of smelly compounds, such as hydrogen sulfide and methyl mercaptan.
What You Can Do
Diet
Drinking plenty of water helps flush out bacteria and food particles that cause bad breath. Reducing sugary and acidic foods prevents harmful bacteria growth while eating crunchy fruits and vegetables stimulates saliva production. Including fermented foods like yogurt and ginger can support digestion and improve bad breath linked to gut issues.
Supplements
Probiotics can help balance the oral microbiota and support healthy digestion, potentially reducing bad breath. For low stomach acid, consider apple cider vinegar or digestive bitter herbs to stimulate stomach acid secretion.
Lifestyle
Natural supplements such as apple cider vinegar and bitters can help support fresh breath by improving digestion and balancing stomach acid. Probiotics may aid in balancing gut bacteria, which can reduce bad breath related to digestive issues. Additionally, chewing gum with xylitol can stimulate saliva production and help manage bad breath.
How My Client Solved Persistent Bad Breath
One of my patients came to me with persistent bad breath that just wouldn’t go away, even though she was meticulous about her oral hygiene. After digging deeper, we discovered that she had low stomach acid and an imbalance in her oral microbiome, particularly due to SIBO (small intestinal bacterial overgrowth, a common root cause of irritable bowel syndrome). SIBO can lead to bad breath because it causes an overgrowth of bacteria in the small intestine, which produces smelly compounds that are released in the breath.
To address the problem, we used natural remedies to clear the SIBO and focused on rebalancing her oral microbiome with specialized toothpaste and mouthwash. This approach not only eliminated her bad breath but also stopped it from coming back, demonstrating the importance of addressing the root cause rather than merely masking the symptoms.

3. Frequent Colds and Infections
What’s Happening in Your Gut
If you’re catching colds and infections more often than usual, it might be a sign that your immune system isn’t as strong as it should be—and this often ties back to your gut health. Since your gut houses about 70% of your immune system, issues like leaky gut, food allergies, and imbalances in gut bacteria—especially with an overgrowth of harmful bacteria—can weaken your immune defenses. An overworked immune system, constantly battling chronic allergies and infections, has fewer resources to fight off new threats, making it easier for you to get sick.
What You Can Do
Diet
Eat plenty of fruits, vegetables, and whole grains to keep your gut healthy. Add fermented foods like yogurt and kefir to boost good bacteria and support your immune system. Avoid processed and sugary foods, and cut out any known food sensitivities to lessen stress on your immune system.
Supplements
Probiotics can help balance your gut bacteria and support your immune health. Vitamin C and Vitamin D are also useful for boosting immunity and fighting off infections.
Lifestyle
Get regular exercise to maintain a healthy gut and strengthen your immune system. Make sure to get enough sleep, as lack of rest can weaken both your gut and immune function. Manage stress through mindfulness or relaxation techniques to prevent it from negatively affecting your gut and immune health.

A Teacher’s Surprising Immunity Boost
I recall a client who initially came to me for IBS-related issues. During our sessions, we discovered that she had both food sensitivities and an imbalance in her gut bacteria. We addressed these problems with a personalized approach including dietary changes and gut-healing protocols.
Interestingly, she mentioned that every January she would get sick, experiencing severe sinus infections and colds due to her role as a teacher. This year, however, she was amazed to find that she did not get sick at all. It was the first time in years she had been free from illness during this time of year.
By rebalancing her gut bacteria and removing the foods that triggered her sensitivities, we were able to help her immune system work better. Even though she didn’t come to me specifically for immune support, fixing her gut health ended up having a big positive impact on her overall wellness.

4. Food Intolerances
What’s Happening in Your Gut
Food intolerances often start with an unhealthy gut, leading to two main problems: trouble digesting certain foods and too much fermentation. When your gut is inflamed or its lining is damaged, it can’t break down certain foods properly, causing intolerances. Additionally, an overgrowth of harmful bacteria in your gut can lead to bad gut bacteria symptoms like bloating, gas, diarrhea, and stomach pain.
A lack of beneficial bacteria can exacerbate these symptoms by failing to maintain balance in the gut microbiome. Together, these issues can make eating uncomfortable and challenging, turning meals into a source of discomfort instead of enjoyment.
What You Can Do
Diet
Start with a gut-healing diet that includes anti-inflammatory foods like leafy greens and omega-3s. Avoid common triggers such as gluten, dairy, and high-FODMAP foods to prevent worsening symptoms. Keeping a food diary and eating smaller, more frequent meals can help identify and manage triggers, reducing digestive strain.
Supplements
Digestive enzymes can help break down difficult foods and reduce intolerance symptoms, while probiotics balance gut bacteria to ease bloating. Glutamine supports gut lining repair and peppermint oil can relieve bloating and gas by relaxing digestive tract muscles.
Lifestyle
To help with digestion and food intolerances, take two minutes to breathe deeply before each meal to relax your body. Chew your food well, around 30-40 times, to make digestion easier. Staying hydrated and staying active also support healthy digestion and gut motility.
How Gut Health Revived Ashley’s Diet
Ashley came to me with severe digestive issues that had been plaguing her for nine months. She was struggling with daily diarrhea, bloating, gas, and fatigue despite trying multiple restrictive diets.
When we began working together, our main goal was to pinpoint which foods were causing her problems. However, it quickly became clear that her gut was significantly out of balance, affecting her ability to tolerate a wide range of foods.
We took a detailed approach, figuring out not just which foods were causing her issues but also working on healing and rebalancing her gut. With this comprehensive plan, she was able to slowly start eating foods that had previously caused problems.
The change was incredible—her symptoms vanished, and she felt better than she had in months. Ashley was thrilled to enjoy her favorite foods again without any discomfort, proving how effective a well-rounded approach that addresses root causes, not just food elimination, can be.
5. Unexplained Weight Changes/Difficulty Losing Weight
What’s Happening in Your Gut
If you’re seeing unexpected weight changes, like gaining weight or struggling to lose it, your gut health might be playing a role. Specifically, the methane type of SIBO is often linked to weight issues. Methane-producing bacteria can slow down your metabolism and cause poor digestion symptoms like bloating, constipation, and poor nutrient absorption, which can make weight management more difficult.
Plus, inflammation and a leaky gut can disrupt your hunger and fullness signals, making weight loss even more challenging. Additionally, imbalances in gut bacteria can affect how well your body can regulate blood sugar, further complicating weight management. For a deeper look at how your gut affects your metabolism and weight, check out my podcast episode on how an unhealthy gut affects weight.
Diet
Eat consistent, balanced meals to keep your metabolism steady and blood sugar levels stable. Try a low-FODMAP diet to prevent feeding bacteria that can cause inflammation and digestive issues. Include fiber-rich, low-FODMAP foods to support digestion and help manage your weight.
Supplements
Spore-based probiotics might help with weight loss by lowering harmful substances in the blood and reducing inflammation, which can help decrease hunger and lower fat levels in the body. Polyphenols may reduce inflammation and support metabolic health. Adding a fiber supplement can aid digestion and assist with weight management.
Lifestyle
Practice mindful eating by chewing your food well and tuning into your hunger cues. Get regular exercise to boost your metabolism and support gut health. Manage stress with deep breathing or meditation, as stress can affect both your weight and digestion.
How Tackling Methane Overgrowth Transformed My Client’s Weight
One client came to me feeling incredibly frustrated. She was battling severe constipation and bloating, and even though numerous medical tests came back normal, her symptoms persisted. To make matters worse, she was gaining weight despite sticking to a great diet and working out regularly.
After a detailed evaluation, we found that methane overgrowth, consistent with SIBO, was disrupting her digestion and complicating her weight management. We adjusted her eating patterns and calorie intake while implementing a protocol to address the methane overgrowth.
Initially, this helped stop her weight gain—a welcome relief— but it wasn’t until we tackled the methane that she finally saw her weight start to drop. The transformation was incredible, and she was thrilled to finally understand how her gut issues were linked to her weight problems and to see the results she’d been hoping for.

6. Mood Swings and Anxiety
What’s Happening in Your Gut
Mood swings and anxiety can often be traced back to imbalances in your gut, thanks to the gut-brain axis—a communication system that links your digestive tract and brain. When your gut flora is out of balance, like having too many harmful bacteria or not enough good ones, it can affect neurotransmitter production and stress hormone levels. Since hormones like serotonin and dopamine, which play a significant role in regulating mood and mental health, are produced in the gut, imbalances can lead to mood swings and increased anxiety.
What You Can Do
Diet
Maintain a balanced diet with lots of fruits, vegetables, lean proteins, and fiber to keep your gut healthy and mood steady. Add omega-3-rich foods like fatty fish and tryptophan-rich foods like turkey and bananas to help boost serotonin levels. Try to limit sugar and processed foods, as they can upset your gut balance and affect your mood.
Supplements
Consider taking probiotics like Lactobacillus rhamnosus and Bifidobacterium longum to balance gut bacteria and support mood by aiding neurotransmitter production. Omega-3 supplements can help reduce inflammation and improve mood, while adding magnesium to your diet or taking a supplement may also help stabilize your mood and reduce stress.
Lifestyle
Practice stress-reducing techniques like mindfulness, meditation, or yoga to support your gut-brain connection. Regular exercise and good sleep hygiene are also key for boosting mood and maintaining gut health. Consider therapies like gut-directed hypnotherapy and EMDR to address both gut issues and emotional stress.
Kim’s Journey From Gut Anxiety to Choir Confidence
When Kim first came to me, she was overwhelmed and anxious. Her gut issues, including persistent bloating and fear of sudden bathroom runs, were preventing her from enjoying her favorite activities—road trips with friends, hiking, and singing in her Sunday morning choir. Even on good days, the mere thought of going out could trigger her anxiety, leading to the very symptoms she feared.
We approached her situation holistically. I guided Kim in identifying her food triggers, addressing her gut imbalance, and managing her anxiety. Although her anxiety didn’t vanish overnight, as her gut issues improved, she started experiencing fewer anxiety-triggered episodes.
Over time, Kim regained her confidence and resumed her activities. I remember vividly when she said, “Alyssa, I sang in the choir again last weekend!” Kim was thrilled to return to her passions without constant worry, really showing the importance of addressing both physical and emotional health.
7. Cravings for Sugar
What’s Happening in Your Gut
If you’re constantly craving sugary foods, it might be more than just a sweet tooth. These cravings could be a sign that your gut health is off balance. When your gut isn’t working well, it can lead to intestinal issues like an imbalance in gut bacteria or an overgrowth of yeast. These problems can manifest as various gut symptoms, such as bloating and discomfort, and can disrupt your blood sugar levels, increasing the production of chemicals that make you crave even more sugar.
Here’s what’s happening: An unhealthy gut can affect how your body manages blood sugar, causing spikes and drops that fuel intense sugar cravings. Plus, eating sugary foods can worsen the imbalance in your gut, creating a cycle where the more sugar you eat, the more you crave. This cycle makes it feel like you’re constantly battling cravings and feeling guilty, but the real issue is that your gut needs some care to break free from this pattern.
What You Can Do
Diet
To control blood sugar and reduce sugar cravings, cut back on refined sugars and processed foods. Opt for low-sugar fruits, high-fiber vegetables, and protein-rich snacks to maintain steady energy levels. Adding coconut oil, with its antifungal properties, can also support gut health and manage yeast overgrowth.
Supplements
Saccharomyces boulardii is a probiotic yeast that helps restore gut balance and manage yeast overgrowth, which can be beneficial for controlling sugar cravings. Additionally, spore-based Bacillus subtilis can help inhibit yeast growth and support overall gut health. Adding a chromium supplement can aid in regulating blood sugar levels and reducing cravings.
Lifestyle
To manage sugar cravings and potential yeast overgrowth, practice mindful eating by savoring each bite and paying attention to hunger cues, which helps prevent overeating. Regular physical activity, such as walking or cycling, can stabilize blood sugar levels and reduce cravings while supporting overall gut health. Staying hydrated with water and herbal teas like cinnamon or ginger can help curb cravings for sugary drinks and support digestive balance.
Lisa’s Sweet Success: Tackling Yeast and Sugar Cravings
One of my patients, Lisa, was really struggling with intense sugar cravings, to the point she believed she just had no willpower. Imagine her surprise when we discovered that yeast overgrowth in her gut was the real culprit. The yeast was feeding on the sugar she consumed, making her cravings even worse.
To address this, we started by stabilizing her blood sugar with a new eating plan. We also introduced naturally sweet substitutes so she could enjoy a sweet taste without the negative effects. As we worked on resolving the yeast issue, her cravings gradually began to fade.
Lisa was thrilled to see her cravings disappear once we addressed the root problem. It was a huge relief for her, especially since she’d been blaming herself for so long when it was actually her gut microbes driving those cravings. This breakthrough was a great example of how looking deeper and thinking outside the box can lead to more effective and lasting solutions.

8. Joint Pain
What’s Happening in Your Gut
Joint pain can sometimes be an unexpected sign of gut health issues. The connection between gut health and joint pain is often through inflammation. When your gut isn’t functioning well, such as with leaky gut syndrome or an imbalance in gut bacteria, it can lead to inflammation throughout your body.
This inflammation can cause joint pain, stiffness, or discomfort because your immune system is reacting to problems in your digestive system, and the inflammation can spread into your bloodstream, affecting your joints. So, if you’re experiencing joint pain, it might be a good idea to check on your gut health.
What You Can Do
Diet
Focus on an anti-inflammatory diet rich in fruits, vegetables, and fatty fish like salmon to reduce overall inflammation. Avoid processed foods, refined sugars, and seed oils, as these can exacerbate inflammation and gut issues. Incorporate bone broth and turmeric into your meals, as they have natural anti-inflammatory properties that can support joint health.
Supplements
Consider taking omega-3 supplements, which help reduce inflammation and support joint health. Turmeric or curcumin supplements can also be effective in reducing inflammation and alleviating joint pain. Additionally, a high-quality probiotic can help balance gut bacteria and reduce systemic inflammation impacting your joints.
Lifestyle
Engage in regular, low-impact exercise, such as swimming or yoga, to maintain joint flexibility and reduce stiffness. Prioritize stress management techniques, like meditation or deep breathing, as stress can increase inflammation and exacerbate joint pain. Ensure adequate sleep each night to support overall recovery and reduce inflammation in your body.
How a Diet Solved Gina’s Pain
When Gina came to me, she was struggling with severe joint pain in her hands. Despite seeing rheumatologists and acupuncturists, and trying various medications that only masked her symptoms, her pain wouldn’t go away. It was impacting her sleep, weight, and motivation, and she felt pretty hopeless.
So, I decided to try a different approach. I created a personalized anti-inflammatory eating plan for her, using a food sensitivity test to pinpoint which foods were triggering her pain. Within just a few weeks, Gina started feeling a lot better. Her joint pain eased up, and she became more focused and motivated.
The results were truly transformative for Gina. Instead of relying on medications that merely masked her symptoms, our natural approach addressed the root cause of her pain. By focusing on reducing inflammation with a personalized diet, Gina not only relieved her joint pain but also improved her overall health, helping her avoid having to resort to heavier medications.
9. Sleep Disturbances
What’s Happening in Your Gut
Struggling with sleep issues might be more about your gut than you realize. Your gut plays a key role in managing sleep because it helps produce neurotransmitters and hormones that regulate your sleep-wake cycle. For example, a healthy gut produces serotonin, which is needed to make melatonin, the hormone that helps you fall asleep and stay asleep.
When your gut is out of balance—due to signs of poor gut health such as poor gut bacteria, inflammation, or leaky gut syndrome—it can impact this process. This imbalance can disrupt your body’s ability to produce serotonin and melatonin, making it harder for you to get a good night’s sleep. Additionally, digestive discomfort, like bloating or pain, can keep you awake or disrupt your sleep.
Diet
Support your gut health with a diet rich in fiber from vegetables and fruits, and fermented foods like yogurt, which help balance gut bacteria and aid in producing sleep-regulating hormones. Avoid caffeine and heavy meals close to bedtime, as they can disrupt your sleep and worsen digestive issues. Include foods high in tryptophan, such as turkey and bananas, to help boost serotonin and melatonin levels.
Supplements
Try a probiotic with strains like Lactobacillus and Bifidobacterium to promote a healthy gut and improve sleep. Magnesium can help with relaxation and sleep quality by soothing muscles and reducing stress. Melatonin supplements may also be useful if you struggle to fall asleep, as they help regulate your sleep-wake cycle.
Lifestyle
Stick to a regular sleep schedule by going to bed and waking up at the same time each day to regulate your sleep patterns. Create a restful environment by keeping your bedroom cool (60-70°F), using white noise if needed, and minimizing blue light exposure by avoiding screens 1-2 hours before bed. Relax before sleep with calming activities like deep breathing or reading, and consider using a weighted blanket for added comfort.
How Maria Ended Exhaustion
Maria came to me feeling completely exhausted despite getting a full eight hours of sleep every night. She’d been battling severe bloating and uncontrollable diarrhea for over a decade, and nothing seemed to help. Traditional treatments just weren’t cutting it for her.
The breakthrough for Maria was identifying and removing the foods that were feeding her gut bacteria imbalance and driving leaky gut, which was contributing to her fatigue. We created a comprehensive plan focused on improving her gut health through dietary changes and eliminating these problematic foods. Within just six weeks, Maria experienced a remarkable turnaround – the bloating and embarrassing diarrhea vanished, and she started waking up feeling genuinely refreshed and full of energy.
Maria was thrilled with the transformation. For the first time in years, she felt vibrant and had energy to spare. She stopped falling asleep during car rides and could truly enjoy spending time with her grandkids. Her story is a perfect example of how addressing the root cause of gut issues can lead to a complete life transformation!
10. Brain Fog
What’s Happening in Your Gut
Brain fog might actually be connected to signs of poor gut health. When your gut isn’t in good shape, it can impact your brain in several ways. For instance, an imbalance in gut bacteria can lead to bad gut health symptoms such as inflammation, which can make you feel mentally sluggish.
Poor gut health can also lead to nutrient deficiencies, as your body might not absorb essential vitamins and minerals properly, which are crucial for brain function. Additionally, toxins from harmful gut bacteria or yeast can enter your bloodstream and affect your cognitive abilities. Improving gut health through better diet, proper supplementation, and reducing inflammation can help clear brain fog and improve your mental clarity and focus.
What You Can Do
Diet
Focus on eating anti-inflammatory foods like leafy greens, berries, and fatty fish to help reduce inflammation in your gut and boost brain health. Include nutrient-rich foods such as nuts, seeds, and whole grains to support brain function and address potential deficiencies. Avoid processed foods and too much sugar, as they can worsen gut inflammation and contribute to brain fog.
Supplements
Try taking a high-quality probiotic with strains like Lactobacillus and Bifidobacterium to help balance your gut bacteria and reduce inflammation. Omega-3 supplements, such as fish oil, can support brain function and improve mental clarity. A multivitamin with essential nutrients, including B vitamins and magnesium, can help fill nutritional gaps affecting your cognitive function.
Lifestyle
Get regular exercise, such as brisk walking or strength training, to improve blood flow and support both gut and brain health. Use stress management techniques like mindfulness or deep breathing to lower inflammation and enhance mental clarity. Make sure to get enough quality sleep each night to help your brain recover and function better.
How Cathy Cleared Her Brain Fog
When Cathy first came to me, her brain fog was so severe that we couldn’t even finish our initial appointment. She struggled so much to focus on our conversation that I suggested she take a break and we rescheduled. Cathy had been battling a range of issues, including severe headaches, high anxiety, poor sleep, weight gain, and digestive flare-ups.
Cathy had already tried a low FODMAP diet and a gluten-free plan with another dietitian but kept experiencing frequent flare-ups, with only slight improvement in her anxiety and brain fog, She was still struggling with ongoing symptoms and weight gain, so we took a different approach. We focused on rebalancing her gut bacteria to cut down on the toxins they were producing, healing her gut, and boosting her nutrient intake.
Over the next few months, Cathy’s brain fog started to lift, and she felt clearer and more herself. She was laughing more, engaging fully in life, and her vibrant personality came back. Her progress really shows how fixing gut imbalances can make a huge difference in cognitive function and overall quality of life.
