Did you know that your intestine houses more than 100 trillion microorganisms? This gut microbiome — also called intestinal flora — weighs up to 1.5 kg and constitutes a true organ in its own right, at the heart of your digestion, immunity, metabolism... and even your mood.

What is it composed of?

The gut microbiome is a complex ecosystem made up of:

  • Bacteria (e.g., Bacteroides, Lactobacillus, Clostridium, Ruminococcus)
  • Viruses
  • Non-pathogenic fungi
  • Commensal parasites

These microorganisms live mainly in the colon, where the density is maximum. Their distribution varies according to the areas of the digestive tract.

The fragile balance: the 10% threshold

Bacteria Category Ideal Percentage Main Role
Neutral ~70% Passive presence
Beneficial (probiotics) ~20% Protection, digestion, immunity
Pathogenic (bad) <10% Inflammation, diseases if proliferation

Above 10% pathogenic bacteria, the risk of dysbiosis increases.
Below 10% pathogenic bacteria, your microbiome remains protective and functional.

The consequences of imbalance

When bad bacteria exceed the critical threshold, they can:

  • Trigger silent chronic inflammation
  • Disrupt the intestinal barrier
  • Release toxins and harmful metabolites
  • Affect the brain via the gut-brain axis

This promotes the appearance of diseases such as:

  • Alzheimer's, Parkinson's
  • Type 2 diabetes
  • Digestive cancers
  • Autoimmune diseases
  • Metabolic and cardiovascular disorders

How to know if you are above 10%?

Here are the warning signs of an unbalanced microbiome:

  • Bloating, gas, constipation, diarrhea
  • Acid reflux or slow digestion
  • Joint or muscle pain
  • Frequent headaches
  • Chronic fatigue or sleep disorders
  • Irritability, anxiety, decreased concentration

👉 These symptoms often indicate a rate of bad bacteria close to 20%.

How to rebalance your microbiome?

At Family Clinic, we offer an integrated approach:

  • Digestive assessment
  • Personalized nutritional protocols
  • Patient education
  • Follow-up and health coaching

Key takeaways

  • The microbiome is an invisible but vital organ
  • The 10% threshold of pathogenic bacteria is a key indicator
  • Digestive or joint symptoms can signal an imbalance
  • It is possible to naturally rebalance your intestinal flora

Your gut microbiome plays a fundamental role in your overall health. By maintaining the balance below that critical 10% threshold, you're investing in your long-term wellness and preventing numerous health complications.
