New study to track hidden salt and mineral imbalances in sick kids

This study will look at 150 infants and children aged 1 month to 4 years who are admitted to a hospital gastroenterology unit with a gastrointestinal disease. The goal is to find out how common electrolyte disturbances (like low sodium or potassium) are in these children. By measuring these imbalances, researchers hope to better understand the problem and improve future care.
