Fecal Fat Analysis: A Simple Test to Detect Fat Malabsorption

Discover how a simple fecal fat analysis can reveal fat malabsorption and why it’s a powerful first step in understanding digestive health. A fecal fat analysis can detect when the body isn’t absorbing dietary fats properly, which may explain symptoms like oily stools, weight loss, or persistent abdominal discomfort. When clinicians suspect malabsorption, a fecal fat analysis is often recommended because it provides a direct measure of fat loss in stool, helping to pinpoint where things might be going wrong in digestion and absorption. Typically, a fecal fat analysis is performed as a 72-hour stool collection. You’ll record all stools and dietary fat intake over that period, then ship the samples to a lab for fat quantification. The test reports fat excretion in grams per day, with higher values suggesting fat malabsorption. The results guide diagnosis by narrowing down possible causes—pancreatic insufficiency, bile acid deficiency, celiac disease, or inflammatory conditions—and inform subsequent steps, such as targeted imaging, enzyme therapy, dietary adjustments, or other specialist referrals. Inside the broader landscape of gut health, a platform like InnerBuddies can complement a fecal fat analysis with deep microbiome insights.
