Numerous studies in the past two decades have demonstrated links between gut health and the immune system, mood, mental health, autoimmune diseases, endocrine disorders and skin conditions.
6 Signs of an unhealthy gut

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
High amounts of refined sugars, particularly high-fructose corn syrup, have been linked to increased inflammation in the body.

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. An imbalanced gut can impair your body’s ability to absorb nutrients, regulate blood sugar, and store fat.

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
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.
