Most people walk around with yeast living happily in their gut and never think twice about it. But when that yeast becomes unbalanced and starts to multiply, it can start to affect everything from digestion and mood and even your skin. It is one of the most overlooked root causes of chronic symptoms.

Before I jump into all 10 signs, there is one big clue that people often ignore.
Sign One: Intense Sugar or Carb Cravings
If you have stubborn sugar cravings that just seem impossible to control, it might not just be you not having willpower. Yeast actually feeds on sugar and can influence cravings in order to get more of it.
Now, that's just one sign. We're going to explore the rest of the signs as well so you can understand more about what's going on in your gut.
But first, I'm Katie Bailey. I'm a Gut Health Dietitian at Oswald Digestive Clinic, where we help individuals improve and resolve their bothersome gut issues. If you're interested in learning more about gut health, I'll link our free guide Five Ways to Improve Your Gut Health.

What Is Yeast Overgrowth?
So what exactly is yeast overgrowth? Well, yeast overgrowth is often referred to as candida overgrowth, and it happens when natural microbes in the gut become imbalanced. So yeast is part of a healthy microbiome in small amounts. The problem starts when antibiotics stress high sugar diets a weakened immune system, and long-term use of medications disrupt that balance. Then yeast can begin to overgrow and get out of control and lead to things like inflammation, toxins, and disruption throughout the whole body.
Top Signs of Yeast Overgrowth
So now that we know what yeast overgrowth is, let's go through the top signs that many people miss. We already discussed the first sign, which was intense sugar or carb cravings, but the next sign is digestive issues such as gas, bloating, diarrhea, or constipation.

Sign Two: Digestive Issues
So yeast overgrowth is going to disrupt the balance of those good and those bad microbes in the gut. And this imbalance can lead to more fermentation or over fermentation of carbohydrates in the gut leading to more gas, bloating, and inconsistent bowel habits.
Sign Three: Unexplained Fatigue
Sign three is unexplained fatigue or just feeling exhausted even after rest. So yeast produces compounds that can stress out our liver and slow down detoxification. Our mitochondria, which are our little energy factories in the body, struggle to produce energy efficiently when inflammation levels are high, making us feel more drained.
Sign Four: Brain Fog and Cognitive Changes
Next is brain fog difficulty focusing or poor memory. So toxins from yeast can circulate in the bloodstream and interfere with our neurotransmitter function. Many people describe feeling spacey or forgetful or just that their brain doesn't seem to be firing the way that it should sign.
Sign Five: Reoccurring Yeast Infections or UTIs
Number five is reoccurring vaginal yeast infections or UTIs. So frequent infections suggests that the immune system is having a hard time keeping yeast in check, and this is one of the more classic signs of imbalance.
Sign Six: Skin Issues and Nail Fungus
Next is skin issues like eczema, psoriasis, rashes, as well as nail fungus. So our skin mirrors our gut health. So when yeast breaks down that gut barrier, it can lead to inflammation that can then surface as chronic skin issues. So fungal infections, like on the nails or on the feet, often accompany internal yeast imbalances.
Sign Seven: White Tongue Coating or Bad Breath
Number seven is a white coating on the tongue, oral thresh, or bad breath. So a white coating or Halle ptosis, which is that bad breath, can reflect yeast growing on our mucus membranes in the digestive tract.
Sign Eight: Mood Shifts
Next up is mood shifts like anxiety, depression, or irritability. So the gut produces a large amount of serotonin, and when yeast damages that gut lining or alters the microbiome, this can alter mood regulation.
Sign Nine: Joint or Muscle Pain
Number nine is joint or muscle pain without injury. So yeast triggered inflammation can spread systemically, and this can lead to unexplained stiffness or pain or a sensation of heaviness in the body.
Sign Ten: Weight Changes
And then lastly, trouble losing weight or unexplained weight gain. So yeast disrupts hormones that are involved in our metabolism and our appetite. And when digestion is off or our detox pathways are slowed, weight becomes more difficult to manage.
If several of these signs sounded familiar to you, the good news is there are real steps that you can take to restore balance.
Remove What Feeds Yeast
The first is to remove anything that's going to feed the yeast or contribute to more inflammation. So you'll want to lower your intake of refined carbohydrates and sugar, as that is yeast food supply. Next is to limit alcohol as that also contributes to yeast and can stress out the liver, identify any food sensitivities you might be experiencing that may be contributing to inflammation. And then lastly, you can use evidence-based antifungals like caprylic acid, oregano oil, and garlic to kill off some of that yeast.
Yeast Overgrowth Treatment and How to Repair the Gut Lining
Now, after removing all those things, you want to work on repairing the gut lining. So not only do you want to support digestion, but you also want to incorporate soothing and repairing nutrients like L-glutamine, zinc, carine, and aloe.
Restore Microbial Balance
And then next, you want to restore microbial balance. So you can incorporate targeted probiotics or more fermented food if you tolerate that. Once yeast levels are under control, you also want to solely start increasing fiber and prebiotic fiber specifically as well, like inulin or partially hydrolyzed wire gum as these things help to feed those beneficial microbes.
Support Detox Pathways
And then lastly, support your detox pathways. That looks like having adequate hydration electrolytes on board, gently moving lymph through the body with walking or dry brushing, supporting the liver with milk thistle, turmeric, leafy greens, and cruciferous vegetables. And then lastly, making sure that you're having daily bowel movements to prevent reabsorption of toxins.
Why a Personalized Protocol Matters
Now while this process is powerful, it's not something to dive into blindly. So treatment should not be one size fits all. It's going to depend on your symptoms, your medical history, your lifestyle, any lab testing that you've done. And it's really important to work with a practitioner because killing yeast too quickly can lead to die off reactions, meaning that toxins overwhelm your system and can worsen your symptoms in the process. Some digestive symptoms may have other root causes like SIBO or mold or parasites. And then lastly, medications and supplements can interact with your current health conditions. A personalized approach ensures that you remove yeast at the right pace, you support detox properly, and you rebuild the gut for long-term success.
