What are the symptoms of MCADD?

Most people with MCADD do not show any symptoms unless they are sick, vomiting or not eating well.

Symptoms or signs that may be seen during illness or times of fasting:

• Lethargy – tired and sleepy
• Hypoglycaemia (low blood sugar)
• Vomiting
• Shakiness
• Irritability
  

Left untreated, this can progress to:

• Heart problems
  
• Enlarged liver (hepatomegaly)
• Seizures
• Breathing problems
• Coma
• Death

The health outcome for most individuals with MCADD is excellent. Growth, development and general health are expected to be normal if the diagnosis is made early and emergency treatment is given during periods of illness or poor feeding.

• Is vomiting
• Has diarrhoea
• Has an infection
• Has a fever
