Stool Volume
Stool volume is an important indicator reflecting the functioning of the gastrointestinal tract and the nature of nutrition. The amount of stool expelled per defecation or per day can indicate certain physiological or pathological processes in the body.
Normal values: on average, 100–250 g of stool per day with a balanced diet.
Increased volume (polyfecalia):
- Increased intake of dietary fiber (vegetables, fruits, cereals);
- Accelerated transit of food through the intestines (malabsorption);
- Pancreatic insufficiency, celiac disease, inflammatory bowel diseases;
- Use of laxatives.
Decreased volume:
- Low-calorie or high-protein diet (with fiber deficiency);
- Constipation, spastic bowel conditions;
- Disorders of colon motility.
Measurement and assessment of stool volume is important in diagnosing digestive system diseases and as part of a general stool analysis (coprology).
