There is a lot of evidence showing how poor gut health can affect your overall health.

There are 100 trillion microbes in the gut of an average person, which is 10 times more than the cells in the human body, and they have a significant impact on the entire organism.

Experts reveal five health problems that arise when the gut is out of balance that KP brings you below:

1. Bad mood

Doctor Uma Naidoo points out that the gut is connected to the brain, as 90% of serotonin receptors are located in the gut.

By doing so, your gut can affect your mental health.

"In the relatively new field of nutritional psychiatry, we help patients understand how gut health and nutrition can positively or negatively affect their mood," reveals Naidoo.

She explains that with some antidepressants, such as selective serotonin reuptake inhibitors, the most common side effects are gut-related, which includes temporary nausea, diarrhea and gastrointestinal problems.

“There is a two-way anatomical and physiological communication between the gut and the brain via the vagus nerve.

The gut-brain axis provides us with a better understanding of the link between diet and disease, including depression and anxiety,” reveals Naidoo.

2. Immunological problems

There is a lot of evidence to show that an unhealthy gut can seriously damage the immune system.

The gut microbiome plays an important role in many health functions, one of which is regulating the proper functioning of the immune system.

According to research, changes in gut microbes can cause immune dysregulation, leading to autoimmune disorders.

3. Inflammatory processes

Experts warn that if the intestinal function is not in balance, various inflammations can occur.

Dietitian Gail Cresci points out that the bacteria in the gut help metabolize nutrients from the food we digest.

"These bacteria have metabolic mechanisms for digesting and fermenting fiber, and in response they create beneficial byproducts that we know are anti-inflammatory," Cresci explains.

She warns that in people whose diet is not optimal, for example, it does not contain enough fiber and is high in fat and sugar, the microbiome in the gut changes.

"Instead of producing useful metabolic by-products, bacteria produce substances that are not useful.

This can cause inflammation," Cresci points out.

4. Excess body weight

The bacteria in your gut can directly affect your weight.

One study found that specific metabolites found in blood plasma and stool samples were directly linked to obesity.

"This means that future research should focus more on how the composition of gut bacteria can be changed, in order to reduce the risk of obesity and associated metabolic and cardiovascular diseases," explains Marju Orho-Melander, professor of genetic epidemiology.

5. Sleep problems

"There is growing evidence that the composition of your gut microbiome is related to how well you sleep," says nutritionist Fatema Badri.

Gut health can affect your sleep, and poor sleep can affect gut health in the same way.

"Lack of sleep can affect digestive health by increasing the risk of obesity, type 2 diabetes and gastrointestinal disease," warns Badri, adding that scientists have even found that poor sleep quality is linked to heart problems.
