Understanding care
Clinical care may include prompt metabolic evaluation and ongoing clinician-directed management. A qualified clinician decides which investigations and options fit the individual situation.
When to seek help
Poor feeding, repeated vomiting or unusual drowsiness in a person at risk needs urgent medical assessment. Confusion, seizures, breathing changes or collapse is an emergency; use an existing prescribed illness plan.
For severe breathing difficulty, collapse, suspected stroke, or another emergency, call local emergency services immediately. In India, call 112.
