Can I drive?
Yes, you can drive with PCD. There are no legal or medical restrictions on driving with it. This being said, if you are ever experiencing symptoms of low carnitine (low blood sugar, severe nausea, shortness of breath, severe confusion, etc.) we advise that you refrain from driving and seek help from an adult immediately. If you are alone and unable to drive due to a sudden onset of PCD complication symptoms, call someone who can help you, or 911, before you try to operate a motor vehicle. This is imperative for both your safety and that of others on the road.
Do I have to tell everyone about my diagnosis?
Short answer: no, you don't have to widely broadcast your diagnosis, and it won't be clearly noticeable to your larger community. With that said, we advise that you and your parents strategize about the people in your life who should know. We recommend that your school nurse, camp director, or any adults who will be responsible for you, especially in the case of an emergency, are aware of your diagnosis so they can help correctly if anything goes wrong. It may also be worth considering, as you get older and more independent, telling your closest friends, or the people you associate with most, just in case anything happens so they can get you the help you need in the most efficient way possible.
Can I get a tattoo or piercing?
There's no specific reason PCD alone would prevent this, but mention your condition to the studio and check with your doctor first, especially if you're not sure how your body handles the stress of the procedure.
Will my kids have PCD?
PCD is autosomal recessive, meaning a child needs to inherit a non-working copy of the gene from both parents to be affected. If you have PCD and your future partner isn't a carrier, your kids would be carriers but wouldn't have PCD themselves. A genetic counselor can walk through your specific situation whenever it's relevant to you.
How do I know if my treatment is working, or not working?
The main way you and your medical team track this is through your bloodwork. If your carnitine levels are within the range your physician has set for you and you're feeling like yourself (not unusually tired, not foggy, not weak), your treatment is doing its job. Most people who are supplementing correctly don't notice dramatic effects, because everything is just functioning the way it's supposed to. Signs that something may be off include: feeling unusually fatigued even when you've been sleeping and eating normally, brain fog or difficulty concentrating, muscle weakness, heart palpitations, symptoms of low blood sugar, or just a persistent sense of feeling "off" that you can't explain. If any of these are showing up consistently, tell your parents and reach out to your physician. It doesn't necessarily mean something is seriously wrong, but it's worth checking your levels, as it's always better safe than sorry when it comes to PCD.
Is it okay that I don't think about my PCD very often?
Yes, it's completely okay not to think about your PCD very often. For a lot of people with well-managed PCD, it becomes background noise: part of the routine, not something that takes up much mental space day to day. That's not you being careless; that's what good management looks like.
These answers are general information, not a substitute for advice from your own doctor about your specific situation.
