How Gut Health Impacts Kidney Function: A Vital Connection

how gut health impacts kidney function

Please note: This article is applicable to those with healthy kidneys.

Did you know, our gut is interconnected with the other organs of our body? And the kidney is one of them! Our gut health not just affects digestion but also has a significant impact on the kidneys.

Let’s understand how:
How does gut health affect the kidneys?

The gut-kidney connection is a two-way communication between the gastrointestinal tract and the kidneys. They are primarily connected through the immune system, the microbiome or the good bacteria residing in our gut, and various metabolites produced during digestion. If these stay in balance, it improves digestion, nutrient absorption, and immune function.

The actions of inflammations:

Kidney diseases can be influenced by inflammation caused by an unhealthy gut. Imbalances in the gut result in leaky gut syndrome. This health condition enables harmful bacteria and toxins to pass into our blood vessels, thus causing body-wide inflammation. This causes kidney damage and can increase the progression of CKD.

The impact of oxidative stresses:

Besides inflammations, an unhealthy gut also increases the production of harmful metabolites and leads to oxidative stress i.e. your body experiences a low level of antioxidants. This oxidative stress damages kidney cells and their ability to filter waste from the blood. Over time, this leads to a decline in kidney function. Hence, the management of gut health is extremely crucial, especially for individuals already suffering from kidney disease.

The Role of Diet and Probiotics:

A diet high in processed foods, red meat, and refined sugars can lead to dysbiosis and increase the burden on the kidneys and negatively impact the gut. Hence, a healthy diet rich in fibre, fruits, and vegetables which promotes the growth of good bacteria in the gut is crucial. These bacteria reduce the production of harmful metabolites and prevent minerals from building up in the body. Thus, they slow down the damage to the kidneys.

One such bacteria is probiotics. These live beneficial bacteria improve gut health and reduce the production of uremic toxins. Hence, incorporating probiotics through diet can improve kidney health, especially for those with CKD.
Understanding the role of gut health will allow you to make more informed lifestyle and dietary choices that support your kidney function. This is especially important for patients with CKD or those at risk.
