*In an observational study conducted across 19 medical sites in Spain, adults (≥18 years) with gastrointestinal (GI) impairment were prescribed Vital 1.5kcal as part of routine clinical practice. GI impairment was defined as compromised tolerance by the presence of symptoms such as diarrhoea, nausea, vomiting, bloating, or early satiety. Over 12 weeks, patients experienced improvements in tolerance, including reduced GI symptoms, improved stool consistency, and a reduction in abdominal pain.
