What is Dysbiosis?

Aug. 14, 2024

Antibiotics, especially the broad-spectrum ones, can wipe out a large portion of the gut bacteria, a disruption known as dysbiosis.

About Dysbiosis:

  • It is an imbalance within a community of microorganisms living together — a microbiome.
  • Our bodies are host to several distinct microbiomes — communities of microorganisms that live with us and assist us in various ways.
  • A balanced microbiome is one where there’s a healthy diversity of microorganisms, where no single bacteria, virus or fungus dominates. 
  • It means there’s a lack of diversity and balance. When they’re imbalanced, it changes how they function in your body.
  • It typically occurs when the bacteria in the gastrointestinal (GI) tract — which includes the stomach and intestines — become unbalanced.
  • Cause: It can arise from infections, antibiotic use, or some aspects of a person’s diet.
  • How does dysbiosis affect us?
    • In any microbiome, a lack of diversity and balance can pave the way for one type of microorganism to take over.
    • Dysbiosis makes us more vulnerable to infections from germs living inside and outside of our bodies.
    • It can also interfere with other important services that our microbiomes normally provide for us. 
  • Symptoms: Though it is sometimes asymptomatic, dysbiosis may manifest in abdominal pain, bloating and vomiting.
  • It is also common on your skin. It can be caused by exposure to harmful bacteria or an overgrowth of a single type of bacteria.
  • Treatment:
    • The main premise of treatment is to increase gut microbiome biodiversity. Scientists have developed several ways of treating dysbiosis, including:
      • Fecal microbiota transplantation
      • Probiotic therapy
      • Microbial metabolic pathway therapy
    • If an underlying disease or condition causes it, you’ll need specific treatment for that condition.
