Understanding Leaky Gut: What Science Tells Us About Intestinal Health

Harvard Health calls it a "medical mystery" and "mysterious ailment." Yet this condition, known as leaky gut or intestinal permeability, increasingly appears to play a role in numerous health challenges, from digestive issues to autoimmune conditions and even mental health concerns.

What is Leaky Gut?

Your digestive system is an intricate network spanning approximately 30 feet, with a surface area that could cover a tennis court if spread out flat. This remarkable system does more than process food - it serves as a selective barrier, carefully controlling what enters your bloodstream.

The gut wall consists of millions of cells connected by tight junctions, acting like security guards deciding what passes through and what stays out. When these tight junctions become compromised, we have what's known as "leaky gut" - a condition where substances that should remain in the digestive tract can pass into the bloodstream.
