Fatty Acids and Soaps.
Fatty acids and soaps are breakdown products of fats formed by the reaction of fatty acids with alkaline metal salts (e.g., calcium and magnesium), resulting in soap formation.
- The presence of fatty acids and soaps in stool indicates impaired digestion and absorption of fats.
- Normally, the content of fatty acids and soaps in stool should be minimal or absent.
- Increased amounts of these substances occur in pancreatic diseases (such as 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, especially those related to fat metabolism disorders.
