Cacogastric is a medical adjective describing poor or disordered digestion. It appears in clinical descriptions of patients whose stomachs handle food badly, with symptoms such as prolonged fullness, nausea, or discomfort after eating. The term comes from Greek roots meaning bad stomach and belongs to the older clinical vocabulary, less used now than specific diagnoses like dyspepsia, gastroparesis, or functional dyspepsia. In dietetic practice, a patient described as cacogastric would be assessed for causes ranging from medication effects to motility disorders, and managed with small, frequent, easily digested meals while the underlying problem is investigated.
