Scybala are hardened masses of faeces that accumulate in the bowel as a result of long-term constipation. When stool sits in the colon, water is progressively reabsorbed until the mass becomes dry, compacted, and difficult or impossible to pass normally. They form in chronic constipation, in immobile or elderly patients, and in conditions that slow bowel transit, and they can cause abdominal pain, overflow soiling, and in severe cases bowel obstruction. Treatment starts with softening and clearance under medical supervision, since forcing passage risks injury, followed by prevention: adequate fibre, fluids, movement, and reviewing constipating medications. Scybala are a sign that constipation has been neglected too long, and they warrant proper assessment rather than self-treatment.
