New scientific findings link chronic silent inflammation to severe health risks and chronic diseases

UPDATE - follow-up to Why is everything linked to inflammation now?: Recent medical research reveals that chronic low-level inflammation significantly increases the risk of heart attack and stroke by 43%. Scientists from the MRC Laboratory of Medical Sciences and Imperial College London published these findings in the European Journal of Preventive Cardiology, showing that inflammation causes silent structural damage to the heart years before symptoms appear.

Expert Insights

Oncologist Siddhartha Mukherjee discussed a new hypothesis on the Oprah Winfrey Podcast, stating that chronic inflammation acts as the trigger that wakes up thousands of dormant cancer cells in the human body. Dr. Arpit Bansal, oncology surgeon and chief scientific chair at the Longevity Summit India, notes that modern life presents five main faces of inflammation: ultra-processed food, sleep debt, a disturbed gut, a sedentary body, and the red mind of constant stimulation. Meanwhile, Dr. Vinaya Bhandari from Mumbai's Jaslok Hospital and Research Centre explains that inflammatory signals interact with the brain and blood vessels, contributing to neurological conditions.

Research and Treatment

Dr. Aditya Vidushi from Faridabad's M|O|C Cancer Care & Research Centre notes that chronic inflammation creates a biological environment that promotes malignant transformation, such as stomach bacteria triggering gastric cancer. Senthilkumar Rajagopal, associate professor at REVA University in Bengaluru, states that South Asian populations may have a distinctive susceptibility to chronic low-grade inflammation due to genes, visceral adiposity, insulin resistance, environmental exposures, and lifestyle factors. Experts suggest combining medicine and lifestyle habits to prevent flare-ups, though specific recommendations vary widely among practitioners like Mark Hyman and David Agus.

Context

Chronic low-grade inflammation is a persistent immune response that occurs when the body's defence systems remain constantly activated without an immediate external threat to fight. Unlike acute inflammation, which causes visible redness, swelling, and pain around an injury, silent chronic inflammation often develops without obvious symptoms and can gradually affect various organs and biological systems over many years.
