Glutaric aciduria type 1 (GA1)
Metabolic crisis
Children with GA1 may have episodes known as a metabolic crisis, sometimes early in their life. Symptoms of a metabolic crisis include:
- poor feeding or loss of appetite
- lack of energy
- abnormal movements
- vomiting
- irritability
- breathing difficulties
Its important to get medical help immediately if your baby develops symptoms of a metabolic crisis. Your doctor will give you advice to help recognise the signs.
In some cases, a metabolic crisis may be triggered later in childhood by an infection or illness. The hospital should provide you with emergency treatment instructions to follow if your child is ill, which helps to prevent these symptoms developing.
