Nasal Dysbiosis

Nasal dysbiosis means an imbalance in the tiny living things (microbes) that normally live inside your nose. Just like a garden needs the right mix of plants to stay healthy, your nose needs a balanced mix of bacteria and other microbes. When that balance is upset—too many “bad” microbes and not enough “good” ones—it can lead to irritation, stuffiness, infections, and even breathing problems.

Types of Nasal Dysbiosis

1. Loss of Microbial Diversity
   Normally, a wide variety of bacterial? species live in your nasal passages. When diversity drops—meaning fewer species or too many of one kind—your nose loses its balance. Less diversity can let harmful microbes take over, making infections or allergies more likely Frontiers.

2. Overgrowth of Pathogenic Bacteria
   Some bacteria, like Staphylococcus aureus or Moraxella catarrhalis, are harmless in small amounts but can cause trouble if they grow unchecked. An overgrowth of these pathogens leads to infection?, or irritation, often causing pain?, swelling?, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।" data-rx-term="inflammation" data-rx-definition="Inflammation is the body’s response to injury, infection, or irritation, often causing pain, swelling, heat, or redness. সহজ বাংলা: শরীরের প্রদাহ; ব্যথা, ফোলা বা লালভাব হতে পারে।">inflammation?, congestion, and sometimes chronic? sinus problems JACI Online.

3. Fungal? Dysbiosis (Mycobiome Imbalance)
   Fungi such as Candida can live in the nose without causing harm. But if conditions change—like higher humidity inside your nose—these fungi can multiply and trigger fungal? sinusitis, with symptoms like nasal blockage and itching PMC.

4. Viral? Dysbiosis
   Viruses (e.g., rhinovirus, influenza) can alter bacterial? and fungal? communities indirectly by damaging nasal cells and changing immune responses. After a viral? cold, you may find your nose more prone to bacterial infections because the normal balance was upset PMC.
