How does the gut microbiome affect your health?
The incredible complexity of the gut and its importance to our overall health is a topic of increasing research in the medical community.
StudiesTrusted Source over the past few decades have found links between gut health and:
the immune system
mental health
autoimmune diseases
endocrine disorders
gastrointestinal disorders
cardiovascular disease
cancer
A higher level of diversity in gut bacteria may be associated with improved health. While research is ongoing, it appears clear that your gut health plays a role in many areas of your health and well-being.
7 signs of an unhealthy gut
Many parts of modern life can affect your gut microbiome, including:
high stress levels
too little sleep
eating a Western diet high in processed and high sugar foods
taking antibiotics
This in turn may affect other aspects of your health, such as:
immune function
hormone levels
weight
development of diseases
You may notice a few symptoms if you have reduced gut health. Here are seven of the most common signs:
1. Upset stomach
Stomach disturbances can all be signs of an unhealthy gut. They include:
gas
bloating
constipation
diarrhea
heartburn
A balanced gut will have less difficulty processing food and eliminating waste, likely leading to fewer symptoms.
2. A high sugar diet
A diet high in processed foods and added sugars can decrease the amount of “good” bacteria and diversity in your gut.
ResearchTrusted Source suggests that this may lead to increased inflammation throughout the body. Inflammation can be the precursor to several diseases, including cancer.
3. Unintentional weight changes
Gaining or losing weight without changing your diet or exercise habits may be a sign of an unhealthy gut. An imbalanced gut can impair your body’s ability to absorb nutrients, regulate blood sugar, and store fat.
Weight loss may be caused by malabsorption because of small intestinal bacterial overgrowth (SIBO). On the other hand, weight gain may be caused by insulin resistance or increased inflammation.
4. Sleep disturbances or constant fatigue
ResearchTrusted Source indicates that an imbalance in gut bacteria may be linked to fragmented sleep and short sleep duration, which may lead to chronic fatigue.
While the cause remains unclearTrusted Source, it appears to be connected to inflammation, metabolic function, and mental health.
5. Skin irritation
Skin conditions like psoriasis may be related to types of bacteria present in the gut. Lower concentrations of beneficial bacteria may impact the body’s immune system.
This, in turn, may lead to conditions that affect the organs, including the skin.
6. Autoimmune conditions
Many studies have found connections between the gut and the immune system. 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.
Research indicates that food intolerances, like lactose intolerance, may be caused by poor quality of bacteria in the gut. This can lead to trouble digesting the trigger foods and symptoms like:
bloating
gas
diarrhea
abdominal pain
nausea
There is also some research indicating that food allergies may be related to gut health.
