How to Improve Gut Health Naturally
Your gut health plays a critical role in your overall well-being, influencing everything from digestion to mental health. That’s why many people seek out how to improve gut health naturally.
Research has increasingly emphasized the importance of maintaining a healthy gut microbiome, with studies showing its profound impact on various aspects of health.
With rising awareness about the importance of the gut microbiome, taking steps to improve and maintain a healthy gut has become a key focus for many.
In this guide, we explore the importance of gut health, signs of an unhealthy gut, actionable tips to nurture your gut microbiome and science-backed strategies for how to improve gut health naturally.
What is the gut microbiome?
The gut microbiome refers to the trillions of microorganisms, including bacteria, fungi and viruses, that reside in your digestive tract. These microbes are essential for various bodily functions, such as:
Ad

- Digestion: Breaking down complex carbohydrates, proteins and fats.
- Immune support: Training the immune system to recognize harmful pathogens.
- Vitamin production: Synthesizing essential nutrients, like B vitamins and vitamin K.
- Regulating inflammation: Helping maintain a balanced inflammatory response.
A balanced microbiome is crucial for good health, while an imbalance — known as dysbiosis — can contribute to a range of health issues.
Gut microbiome and health
Your gut microbiome doesn’t just affect your digestion — it influences many other aspects of health, including:
1. Mental health
The gut-brain axis connects the gut to the brain. Thus, an imbalanced microbiome may contribute to anxiety, depression and stress.
In fact, research published in Nutrients linked gut dysbiosis to increased anxiety and depression.
Gut bacteria directly affect the gut-brain axis by producing neurotransmitters like serotonin.
2. Immune function
About 70 percent to 80 percent of the immune system is housed in the gut. Unsurprisingly, then, a healthy microbiome enhances immune defenses.
Studies have found that individuals with a diverse microbiome were better able to fight infections, underscoring the microbiome’s role in immune health.
3. Metabolic health
The gut affects how the body processes energy, potentially impacting weight regulation and conditions like diabetes.
Research published in the Lancet demonstrated that gut bacteria can influence obesity and insulin resistance through their role in energy regulation and fat storage.
4. Skin health
Conditions like acne, eczema and rosacea can be linked to gut health. Extensive research published in the Annals of Dermatology in 2020 detailed how issues with gut health can play a role in developing atopic dermatitis, psoriasis, rosacea and other unpleasant skin conditions.
Given all the ways an unbalanced gut microbiome can negatively influence health, it’s no wonder people are searching for how to improve gut health.
Signs of an unhealthy gut
An imbalanced or unhealthy gut can manifest in several ways, including:
- Digestive issues, such as as gas, bloating, diarrhea or constipation. Studies have confirmed that imbalances in gut bacteria are associated with irritable bowel syndrome.
- Unexpected weight changes: Gaining or losing weight without changes in your diet or exercise routine may signal gut health issues. Research has revealed that gut dysbiosis could lead to altered energy harvesting from food, causing unintentional weight loss or gain.
- Sleep troubles and chronic fatigue: Poor gut health can disrupt the production of serotonin, which affects sleep and energy levels. Research published in Nutrients indicated that individuals with disrupted gut microbiota experienced poorer sleep quality and higher levels of fatigue.
- Frequent infections due to weakened immunity caused by an imbalanced microbiome. A compromised microbiome could weaken immune defenses.
- Skin problems: Persistent acne, eczema or psoriasis can be a sign of an unhealthy gut.
- Food intolerances: Difficulty digesting certain foods can be due to issues with the gut.
- Mood swings: Anxiety, depression, chronic fatigue and mood swings may be related to issues with the gut microbiome.
- Autoimmune issues: A disrupted gut can increase inflammation and may contribute to autoimmune diseases. A review in Rheumatology and Immunology Research suggested that an imbalanced gut microbiome contributes to increased risk of autoimmune diseases, like rheumatoid arthritis.
How to improve gut health
Wondering how to improve gut health naturally?
Improving gut health requires a combination of dietary changes, lifestyle adjustments and proper stress management.
1. Eat a diverse diet
Consuming a variety of fruits, vegetables and whole grains promotes a diverse microbiome. In fact, a 2023 review of interventional studies relayed that a diet rich in diverse plant-based foods enhances microbiome diversity and improves overall health.

2. Add probiotics
Fermented foods like yogurt, kefir, sauerkraut and kimchi introduce beneficial bacteria, which is why they’re also known as probiotic foods.
A study out of Stanford showed that consuming fermented foods like yogurt and kefir can increase the abundance of beneficial gut bacteria and decrease inflammatory proteins.
3. Focus on prebiotics
Prebiotic-rich foods like garlic, onions, bananas and oats feed the good bacteria in your gut. Research has confirmed that prebiotic fibers found in foods like garlic and bananas promote the growth of beneficial bacteria.
4. Stay hydrated
Proper hydration supports digestion and nutrient absorption. A 2024 study highlighted how proper hydration helps maintain the mucosal lining of the gut and supports bacterial function.
5. Manage stress
Practices like yoga, meditation and deep breathing can help reduce gut-harming stress.
6. Get the proper amount of sleep
Aim for seven to nine hours of quality sleep per night to support gut and overall health. For instance, it’s been found that sleep deprivation negatively affects the gut microbiome, leading to increased inflammation.
7. Eat slowly
Practice mindful eating by chewing your food thoroughly to aid digestion and reduce strain on your gut. Research has suggested that eating slowly improves digestion and reduces gut discomfort.
8. Address food intolerances
Identify and eliminate foods that trigger negative symptoms to avoid further gut irritation by following an elimination diet.
Eliminating trigger foods can help reduce gut inflammation and symptoms like bloating.
