High stress levels, too little sleep, eating processed and high-sugar foods, and taking antibiotics can all damage our gut microbiome. This in turn may affect other aspects of our health, such as the brain, heart, immune system, skin, weight, hormone levels, ability to absorb nutrients, and even the development of cancer.
There are a number of ways an unhealthy gut might manifest itself.
Here are some of the most common signs:
1. Upset stomach
Stomach disturbances like gas, bloating, constipation, diarrhea, and heartburn can all be signs of an unhealthy gut.
2. A high-sugar diet
A diet high in processed foods and added sugars can decrease the amount of good bacteria in your gut. This imbalance can cause increased sugar cravings, which can damage your gut still further. High amounts of refined sugars, particularly high-fructose corn syrup, have been linked to increased inflammation in the body. Inflammation can be the precursor to a number of diseases and even cancers.
3. Unintentional weight changes
Gaining or losing weight without making changes to your diet or exercise habits may be a sign of an unhealthy gut. Weight loss may be caused by small intestinal bacterial overgrowth (SIBO), while weight gain may be caused by insulin resistance or the urge to overeat due to decreased nutrient absorption.
4. Sleep disturbances or constant fatigue
An unhealthy gut may contribute to sleep disturbances such as insomnia or poor sleep, and therefore lead to chronic fatigue.
5. Skin irritation
Skin conditions like eczema may be related to a damaged gut. Inflammation in the gut caused by a poor diet or food allergies may cause increased “leaking” of certain proteins out into the body, which can in turn irritate the skin and cause conditions such as eczema.
6. Autoimmune conditions
Medical researchers are continually finding new evidence of the impact of the gut on the immune system. It’s thought that an unhealthy gut may increase systemic inflammation and alter the proper functioning of the immune system. This can lead to autoimmune diseases, where the body attacks itself rather than harmful invaders.
7. Food intolerances
Food intolerances are the result of difficulty digesting certain foods (this is different than a food allergy, which is caused by an immune system reaction to certain foods). It’s thought that food intolerances may be caused by poor quality of bacteria in the gut. This can lead to difficulty digesting the trigger foods and unpleasant symptoms such as bloating, gas, diarrhea, abdominal pain, and nausea. There is some evidence that food allergies may also be related to gut health.
Here are 6 ways to improve your gut bacteria.
• Eat Lots of Vegetables, Legumes, Beans and Fruit.
• Eat Fermented Foods.
• Don’t Eat Artificial Sweeteners.
• Eat Prebiotic Foods.
• Eat Whole Grains.
• Eat a Plant-Based Diet.
