Ammonia is a nitrogen-containing compound produced in the gut through the breakdown of proteins and amino acids by intestinal bacteria. In a healthy gut, most ammonia is either used by microbes or absorbed and detoxified by the liver. Elevated fecal ammonia levels may indicate excessive protein fermentation, gut dysbiosis, or an imbalance between beneficial and pathogenic bacteria. High levels can contribute to mucosal irritation, inflammation, and may compromise gut barrier function. Ammonia levels are a useful marker of microbial protein metabolism and intestinal health.
It reflects the extent of protein breakdown and fermentation in the gut. Elevated levels often point to microbial imbalance or excessive protein intake.
Potentially yes. Excess ammonia can irritate the gut lining, promote inflammation, and affect the gut-brain axis.
Possible causes include high-protein diets, low fiber intake, dysbiosis, or reduced conversion of ammonia by beneficial bacteria.
Low levels are typically considered favorable, indicating efficient microbial balance and limited protein putrefaction.
Strategies may include reducing excess protein, increasing fermentable fiber, and supporting a healthy microbiota with probiotics or prebiotics.
