Rhabdomyolysis: Causes, Symptoms, and Treatment

What kind of doctor treats rhabdomyolysis?
Rhabdomyolysis is a serious breakdown of muscle tissue that releases harmful substances into the blood. It is treated first by emergency and hospital doctors. In the hospital, people get fluids and careful monitoring of blood salts. Afterward, your concierge or direct primary care doctor can help with follow-up checkups and recovery. Contact a doctor if you notice dark urine, muscle pain, or very little urination.
What is rhabdomyolysis?
Rhabdomyolysis is the breakdown of muscle tissue. It releases the contents of muscle fibers into the blood. These substances are harmful to the kidneys and often cause kidney damage.
When muscle is damaged, a protein called myoglobin is released into the blood. The kidneys filter it out, but it breaks down into substances that can harm kidney cells.
Symptoms
Symptoms may include:
- Dark, red, or cola-colored urine.
- Less urine than usual.
- General weakness.
- Stiff, achy, or tender muscles.
- Weakness of the affected muscles.
Muscle weakness and pain usually occur together. Some people also have tiredness, joint pain, seizures, or weight gain they cannot explain. Many people do not have all the classic signs: muscle pain, weakness, swelling, and dark urine.
Causes and who gets it
Muscle breakdown can come from an injury or other harm to skeletal muscle. These are the muscles you move. Causes include:
- A crush injury or other trauma.
- Some drugs, such as cocaine, heroin, or PCP, and some medicines, such as statins.
- Genetic muscle diseases.
- Very high or very low body temperature.
- Certain infections.
- Seizures or muscle shaking.
- Very hard exercise, such as running a marathon.
- Severe dehydration, which means too little water in the body.
- Long surgery.
How doctors diagnose it
A physical exam will show tender or damaged muscles. Doctors also use blood and urine tests. The standard blood test is the creatine kinase (CK) level.
Treatment
People need fluids with bicarbonate (a type of salt) to help prevent kidney damage. These fluids may be given through a vein (IV). Some people need dialysis, which filters the blood when the kidneys cannot.
Doctors may also give medicines, such as diuretics (water pills) and bicarbonate, if there is enough urine output. High potassium and low calcium in the blood should be treated right away. Kidney failure should be treated too.
Kidney failure happens in many people with this problem. Quick treatment lowers the risk of lasting kidney damage.
You can lower the risk in some cases. Drink plenty of fluids after hard exercise. Avoid drugs or medicines that may cause it. Follow your doctor's instructions about any medicine you take, and do not stop one on your own. For heat stroke, remove extra clothes and put the body in cold water.
When to see a doctor
Contact your provider if you have any of the symptoms listed above. Getting treated soon lowers the risk of permanent kidney damage.
Call 911 or go to the emergency room if you faint, have trouble breathing, or have a sudden change in thinking. Chest pain that lasts two minutes or more is also a reason to call 911.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. These doctors can help with follow-up visits after a hospital stay. They cannot treat serious cases alone, because those need hospital care.
Common questions
What causes rhabdomyolysis?
Rhabdomyolysis can be caused by severe muscle damage, such as intense exercise, a crush injury, seizures, or certain infections. Severe muscle damage lets muscle breakdown products leak into the blood, which can hurt the kidneys. Doctors diagnose it with blood and urine tests.
Is rhabdomyolysis a medical emergency?
Yes, it is serious and needs prompt medical care. It can harm the kidneys and upset the body's blood chemistry, so some people need hospital care. Do not wait for it to get better on its own if you have muscle pain, weakness, and dark urine after intense activity.
Can a direct primary care doctor manage rhabdomyolysis?
A direct primary care doctor cannot treat serious rhabdomyolysis alone because it needs hospital fluids and monitoring. Once you are stable, your primary care or concierge doctor can help with follow-up visits and recovery.
How long does recovery from rhabdomyolysis take?
People with milder cases may return to normal activities within a few weeks to a month. The outcome depends on how much kidney damage there is. Some people continue to have tiredness and muscle pain. Doctors can follow the CK blood test, which falls once the muscle damage stops.
