BulkLaxanzien

BulkLaxanzien refers to a class of laxatives known in English as bulk-forming laxatives. They are agents that increase the volume and water content of the stool by absorbing fluid in the intestine and forming a gel-like mass, which promotes peristalsis and facilitates bowel movements.

Common examples include psyllium husk, methylcellulose, polycarbophil and dietary bran. These products are available in powder, capsule and wafer forms and are widely used for short- and long-term management of constipation, for regulating bowel habits in irritable bowel syndrome, and to improve stool consistency in various clinical settings.

Onset of action typically ranges from 12 to 72 hours after ingestion. BulkLaxanzien generally have a favorable safety profile compared with stimulant laxatives, but they can cause bloating, flatulence and abdominal discomfort, particularly when intake of water is inadequate. A serious but uncommon risk is esophageal or intestinal obstruction if the product is taken without sufficient fluid or in the presence of structural narrowing of the gastrointestinal tract.

Interactions can occur because bulk-forming agents may reduce absorption of certain oral medications; timing of administration is therefore important. They are usually avoided in cases of severe dehydration, fecal impaction or known bowel obstruction. Pregnant people, children and individuals with chronic conditions should consult a healthcare professional before use.
