What Is McArdle Disease?
5. Myoglobinuria
In most cases, the symptoms will have appeared during the patient’s childhood. However, the condition is often not diagnosed until the patient is in their late 20s because it is often not easy to spot that there is a genuine problem. One symptom that can alert people to the fact that there is a real problem is myoglobinuria.
Myoglobinuria is a condition that causes the patient’s urine to take on a burgundy color. It happens when there is more than usual myoglobin in the patient’s blood. Myoglobin is a compound that allows cells to store oxygen, and having high levels of it in the blood is a byproduct of the breakdown of muscle tissue.
