Medium chain acyl dehydrogenase deficiency (MCADD) – Treatment 

Treating MCADD 

Medium chain acyl dehydrogenase deficiency (MCADD) is treated by diet. When the child is well, there is no specific dietary management apart from avoiding long periods without food. During illness, they will need to drink glucose drinks very frequently to keep their blood sugar levels up. Eating regularly is more important than ever when they are unwell.

  • Babies and young children with MCADD need to eat every three to six hours, including at night.
  • Teenagers and adults may be able to go without food for longer periods of up to 12 hours.

Dietary treatment is usually lifelong.

Children should always receive prompt medical attention. If they are unable to eat or drink normally, take them to hospital.
