The Importance of the Gut Microbiome

The gut microbiome refers to the highly important collection of over 100 trillion microscopic and living organisms (also known as the microbiota) that flourish inside your gastrointestinal tract.1


These intestinal organisms—including “good bacteria”—help your body by:2,3

  • Contributing nutrients and energy
  • Protecting against infection
  • Supporting the immune system

When the environment inside your intestine is functioning the way it should, this stable state between the gut microbiome and the intestinal lining is called gut homeostasis.

The gut microbiome can be upset by different factors

When a person has chronic diarrhea and loose stools due to specific intestinal disorders like irritable bowel syndrome with diarrhea (IBS-D), or inflammatory bowel disease (IBD), different factors may upset the delicate balance between the microbiome and the integrity of the intestinal lining, such as:2-9

  • Overgrowth of bacteria in the small intestines. While most bacteria typically reside in the large intestine, difficulty can arise when too many bacteria reside in a person’s small intestine (resulting in small intestinal bacterial overgrowth, also known as SIBO)
  • Exposure to foreign substances called antigens (which cause the immune system to create antibodies against them)
  • External insults like infection or other illnesses
  • Certain dietary ingredients (like lactose in milk products)

When such events occur in the intestinal environment, scientists refer to these changes as altered gut microbiota or intestinal balance (also known as dysbiosis). Inflammation can also lead to microscopic changes at the cellular level in the intestinal lining (also called the intestinal or gut barrier), which can prevent proper absorption of nutrients and water.2

Increases in “leaky gut” can cause problems

You may have heard of “leaky gut syndrome,” which is also known by the medical term of gut barrier dysfunction and altered gut permeability. When your gut barrier is not functioning properly, foreign or even naturally occurring substances that may be toxic to your gut (ie, bacterial endotoxins) can penetrate (get into) the lining of your intestine. This may contribute to symptoms such as:2,4,5,8,9

  • Chronic diarrhea and loose stools
  • Abdominal discomfort
  • Bloating

Address the underlying problem

Imagine how your life might be different if you could:

  • Address the underlying factors that may contribute chronic diarrhea and loose stools due to specific intestinal disorders instead of just trying to minimize them
  • Help manage harmful substances—such as toxic substances released by bacteria and other microbial components—from penetrating the lining of your intestine and upsetting your intestinal environment
  • Do all this with a safe therapy that can be taken alone, or along with any other medications, for as long as you want (under your doctor’s supervision)9

If this is what you are hoping for, ask your doctor about EnteraGam®. EnteraGam® is a medical food product that is not an antibiotic or a probiotic.
