Gut Health


Our immune systems are a very important component of our wellbeing. If it isn’t working to its fullest ability, we will get sick more often. The gut is the home to many good and bad bacteria, this is the makeup of the intestinal tract. Below you can find out all the ways that our immune system can negatively be affected by an unhealthy gut. 

Does Gut Health Affect The Immune System?

There is so much within the body that can be directly affected by the gut. It is the root of so many illnesses and diseases that can happen. There is good bacteria and bad bacteria, and you need an accumulation of both to keep everything running properly. Some of the signs that your gut isn’t healthy are:

  • Stomach Trouble
  • Unable to Manage Weight
  • Restless Sleeping Habits
  • Skin Problems
  • Weakened Immune System
  • Autoimmune Disorders
  • Intolerance To Certain Foods

When the gut doesn’t have the right balance of bacteria in it, you can start to notice a difference in the way your body is fighting off sickness. Your immune system relies on your gut microbiome to thrive. Without gut health, your immune system wouldn’t be able to protect you as well as it should.

How Does The Microbiome Influence The Immune System?

The gut is the root cause of many things that happen in our bodies. Microbiome immune system interaction happens from the beginning of life, helping to shape our immune systems into what they need to be. When you have a healthy cross of these two things, your body can protect you the way that it is supposed to. Some of the factors that can affect your microbiome are:

  • Birth Methods
  • Genetics
  • Diet
  • Infections

Research has shown that over half of the body’s immune cells are in the gut, which means that it is directly affected by the health of the gut. That all goes back to the gut being the root cause of many of the issues that we face. A healthy gut can improve a list of many symptoms that we feel in our bodies. 

Which Probiotics Are Best For The Immune System?

Probiotics could be a good option for people to use that experience gut problems. They can help to promote the growth of healthy bacteria in your gut. Something that can play a big role in the effectiveness of your immune system. Some that are beneficial to your immune system are:

  • Lactobacillus- This one is the most commonly used probiotic. Individuals who are lactose intolerant can find this probiotic helpful in digesting dairy products. 
  • Bifidobacterium- This is the next best to the Lactobacillus and can be a beneficial component to an unhealthy gut.

It is more like a precaution you can take. You may still get sick, but it may be a more mild case then if you weren’t taking them.
