Summarize:

Whether you notice symptoms in you or your child, see the doctor as soon as you can. It's also important to go if you notice a sudden increase in one issue, such as falling or clumsiness, as that could be an indicator of this condition. Make a list of symptoms to take with you. Note how frequently they happen. That way, you won't forget anything while at the doctor's office. Most forms of MD have a genetic component, so your doctor will want to know if it runs in your family. Talk to your doctor if any family members have had specific types of MD. Before doing anything else, the doctor is likely to check you over physically. They'll do things like listen to your heart and breathing, as well as take your blood pressure. The doctor may also ask you or your child to walk so they can check out you or your child's gait. The first test your doctor is likely to run is a blood test. They'll be looking for 2 types of enzymes. The first one, serum creatine kinase, indicates the muscles are deteriorating when at high levels. The second one, serum aldolase, converts sugar into energy, and when your levels of it are high, it can point to muscle weakness. The blood test is also used to determine whether you are carrying the gene for a specific type of MD. Before going to the doctor's office, drink extra water. It's easier for them to take blood when you're hydrated.
Schedule an appointment if you notice symptoms. Discuss your family history with the doctor. Be ready for a physical examination. Expect a blood test.
