If you are a parent or the caretaker of a child with a urea cycle disorder (UCD), you may have many questions on how to best manage their disease. Nutrition, activity, medicine and treatment are all important factors. Here is some information that can help make your role a little easier as well as what steps to take in case of an emergency.

A UCD can cause the amount of ammonia in a child’s blood to rise to unsafe levels. This can make him or her very sick. The symptoms of high ammonia don’t appear quickly. If you’re new to managing a UCD for your child, it may be easy to miss the subtle signs that ammonia is rising. By the time a child with a UCD appears to be sick, it usually means that medical attention is required. If this happens, you should follow the emergency protocol at the end of this section.

To stay healthy and keep ammonia levels in a safe range, following these rules is very important for you and your child:

Watch for common symptoms of high ammonia levels, including sluggishness, staring, nausea or vomiting, irritability, aggression, lack of appetite, slurring words and headaches

If you see the symptoms listed above, it could mean that a hyperammonemic crisis is happening. This is when the amount of ammonia in the blood becomes extremely high. A crisis can be very dangerous and requires medical attention right away. While at the hospital, it is important to notify staff of your child’s urea cycle disorder.

If you care for a child with a UCD, you know that ammonia can be unpredictable. Ammonia can sometimes reach high levels with little warning. Many families keep a go bag packed with essential items for their child to help them get out the door quickly in case a trip to the emergency room is necessary. Having this bag can reassure your child and make his or her trip to the hospital more comfortable.

Use this guide to help you decide what to pack in your own go bag.

Remember: Tell people around you about your child’s go bag. Other family members, friends, teachers, and daycare providers should know where to find the bag and what to do with the contents.
