The health of your gut might seem like a mystery, but it affects more than just your digestion. Surprising indicators like chronic fatigue and skin issues can signal an imbalance in your gut. Here’s a look at five signs your gut health may need attention, along with some research on why it matters and how to support it.
Gastrointestinal Discomfort
Gut issues like stomach aches, cramps, or changes in bowel movements—whether that’s frequent diarrhea or constipation—are often the first sign of an imbalance. These symptoms are commonly associated with Irritable Bowel Syndrome (IBS), a condition linked to gut bacteria diversity. Studies have found that people with IBS often have lower levels of certain bacteria, such as Lactobacilli and Bifidobacteria. Interestingly, IBS is frequently triggered after gut infections, suggesting that bacterial shifts play a large role in IBS development.
Persistent Fatigue
If you feel constantly tired despite getting quality sleep and staying active, your gut health might be to blame. A notable 2017 study discovered abnormal levels of specific gut bacteria in people with chronic fatigue syndrome. Researchers found that bacteria like Faecalibacterium and Coprobacillus influence how fatigued and pained someone feels, underscoring the link between gut health and energy levels. When gut balance is off, it can disrupt the communication between your brain and body, affecting how well-rested you feel.
Skin Problems
Acne, eczema, or other skin troubles can be an unexpected sign of poor gut health. The gut and skin communicate through nutrient absorption, hormones, and immune function. Research suggests that people who take Lactobacillus supplements often experience better skin hydration and reduced sensitivity. Alternatively, a disrupted microbiome can lead to skin issues, as certain amino acid by-products accumulate in the skin. Babies with fewer microbial strains also tend to develop atopic dermatitis, showing how crucial a balanced gut is to glowing skin.
Mood Disorders
Chronic depression or anxiety could also stem from gut imbalance, not just lifestyle factors. The gut-brain connection, known as the brain-gut axis, allows the gut’s neurotransmitters to affect mental health. Research has shown that people with depression often lack specific gut bacteria such as Coprococcus and Dialister, which play a role in mood regulation. Though this research is still evolving, it highlights that a healthy gut could influence how we feel mentally.
Autoimmune Disorders
Autoimmune diseases like Crohn’s or lupus, where the body attacks its own cells, are often linked to gut health. The gut microbiota helps regulate immune response and intestinal barriers. A 2011 study found that disruptions in zonulin, a protein managing gut lining integrity, can increase autoimmune risks, particularly in people predisposed to these diseases. Many scientists believe that antibiotic use and poor diets have negatively impacted our microbiomes, possibly contributing to the rise in autoimmune issues.
Improving Gut Health for a Healthier You
Fortunately, there are ways to support a healthy gut and keep symptoms at bay. Focus on reducing stress, eating a plant-rich diet, staying active, and taking a daily probiotic. A balanced gut doesn’t just benefit your digestion—it enhances your skin, mood, and overall well-being.
