Do you have gastrointestinal concerns? If you have problems with your gut, you may already know that our gut health is a reflection of our overall physical wellness. If your gut health is not in a good state, it is likely that this is reflected in other parts of your physical health. That is because Inadequate gut health affects numerous vital organs, including the skin, immune system, brain, and heart.

And, leaving gut problems untreated can make you more likely to get a number of diseases and long-term conditions. Check out these seven signs of an unhealthy gut if you’re worried that your “tummy troubles” could be a sign of something more serious.

The Most Common Seven Signs Of an Unhealthy Gut

Here are the most common seven signs of an unhealthy gut.

1.     Having Stomach Discomfort Frequently

When your stomach feels disturbed and painful, you might have gas, constipation, diarrhea, bloating, or heartburn. Even though these are common signs, they are not normal. A healthy gut should have no trouble breaking down food and getting rid of waste.

If you have these symptoms often, you should check with your doctor and a nutritionist to make sure you don’t have IBS, an inflammatory bowel syndrome is a common disorder that affects the large intestines [1]. They can tell you what foods you should avoid and what supplements to take.

2.     Unexpected Weight Changes

Losing or gaining weight without modifying your diet plan or exercise routine may be an indication of a gastrointestinal disorder. A gastrointestinal imbalance can impede the body’s ability to control sugar, absorb nutrition, and store fat [2]. The decrease in weight could be due to bacterial overgrowth in the small intestine, whereas insulin resistance or the desire to overeat due to poor food absorption may cause weight gain.

3.     Skin Irritation

Skin disorders such as “eczema” may be associated with a damaged gastrointestinal tract. Gut Inflammation caused by food allergies such as peanut allergy or poor diet may result in an increase in the “leaking” of specific proteins into the bloodstream. This leaking can irritate the skin and causes eczema.

4.     Sleep disorders or continuous fatigue

A gastrointestinal disorder may cause sleep disorders such as poor sleep or insomnia, hence causing chronic fatigue. Serotonin, a hormone that influences both sleep and mood is produced in the intestines. Consequently, any damage to the gut may disturb one’s sleep quality ultimately causing fatigue.

5.     Bad Breath

Maybe it was the garlic bread you ate for dinner, or maybe you forgot to use mouthwash after you brushed your teeth. But bad breath can also mean that your gut isn’t healthy. Anything that got stuck in your digestive system and started to rot can give you bad breath. Bad breath can also be a sign of GERD or bacteria in your stomach that could cause stomach ulcers.

6.     Autoimmune Disorders

Many studies have shown that the gut and the immune system are linked. If the gut isn’t healthy, it can increase inflammation throughout the body and may alter the activity of the immune system. This can cause “autoimmune diseases” in which the body attacks its own cells rather than harmful germs.

7.     A high-sugar diet

A diet high in added sugar and processed foods can reduce the number of beneficial bacteria in the digestive tract. This imbalance can lead to a further increase in sugar cravings, which can harm the gut. Research shows that consumption of large quantities of refined sugars, especially “high-fructose corn syrup”, has been linked to raised inflammation in the body. This inflammation is a precursor for a variety of disorders such as cancer.
