Chronic inflammation is a sustained immune response that can impede the body's natural healing processes. Bacterial infection is a significant contributor to this state because the presence of bacteria can trigger a prolonged inflammatory reaction in the body. When bacteria invade tissue, the immune system responds by sending white blood cells to the site of infection. This response is essential for fighting off the infection, but if the bacteria are not eliminated, the immune response continues, leading to chronic inflammation.

In this context, bacterial infections cause the body to remain in a heightened state of alert, which can disrupt normal healing. Tissues may become damaged, and the healing process is stalled. This chronic inflammatory state can be particularly problematic, as it may lead to additional complications and exacerbate underlying health issues.

On the other hand, biofilms—while they can harbor bacteria and contribute to persistent infections—are a consequence of infection rather than the primary cause of an inflammatory state. A balanced diet and regular exercise are both crucial for maintaining overall health and can help reduce inflammation, not sustain it.
