Intermittent fasting may ease chronic pain through the gut-brain axis

Key Points:

• A study published in Brain, Behavior, and Immunity suggests that intermittent fasting may help manage chronic pain by altering the gut-brain axis, a communication system between the gastrointestinal tract and central nervous system.
• Researchers at Zhengzhou University found that intermittent fasting strengthens the intestinal lining, reducing inflammation by preventing harmful compounds from entering the bloodstream and nervous system.
• The study identified an increase in the gut bacterium Alistipes finegoldii during fasting, which produces compounds converted into hippuric acid that suppresses inflammation through the STING pathway, improving pain and cognitive function.
• While promising, the research is preliminary and observational, highlighting variability in individual responses to fasting due to factors like gut microbiome differences, health conditions, and genetics.
• Intermittent fasting is not a cure for chronic pain, but these findings may inform future therapies targeting gut-brain interactions to alleviate pain and related symptoms.
