Fatty Acids and Soaps

Fatty acids and soaps are products of fat breakdown formed when fatty acids interact with alkaline metal salts (e.g., calcium and magnesium), resulting in soap formation.

• Detection of fatty acids and soaps in stool indicates impaired fat digestion and absorption processes.
• Normally, the content of fatty acids and soaps in stool should be minimal or absent.
• Elevated levels are observed in pancreatic diseases (e.g., chronic pancreatitis), bile secretion disorders, intestinal inflammation, and malabsorption.
• Fatty acids and soaps can irritate the intestinal mucosa, exacerbating inflammation and contributing to diarrhea development.

Analyzing the presence of fatty acids and soaps in stool helps diagnose digestive system pathologies, particularly those related to fat metabolism disorders.
