Rhabdomyolysis
Urgent
Rhabdomyolysis is a condition in which damaged skeletal muscles break down and release their contents into the bloodstream. The released substances, including myoglobin, can injure the kidneys and cause dangerous changes in electrolytes. Symptoms may include severe muscle pain, weakness, swelling, or dark-colored urine, although the full combination is not always present. Severe cases can lead to acute kidney injury and other complications.

When to Seek Medical Attention
Rhabdomyolysis requires prompt medical assessment because breakdown of muscle tissue can cause kidney injury and dangerous changes in blood chemistry. Seek urgent care for severe muscle pain or swelling, marked weakness, or dark or cola-colored urine, particularly after intense exercise, trauma, prolonged immobilization, or another known trigger. Emergency evaluation is appropriate for severe weakness, fainting, confusion, very low urine output, or signs of serious systemic illness.

Overview
Rhabdomyolysis is a condition in which damaged skeletal muscles break down and release their contents into the bloodstream. The released substances, including myoglobin, can injure the kidneys and cause dangerous changes in electrolytes. Symptoms may include severe muscle pain, weakness, swelling, or dark-colored urine, although the full combination is not always present. Severe cases can lead to acute kidney injury and other complications.

Muscle Cramps
Muscle Weakness
Urinary Retention
Causes 1
Rhabdomyolysis can result from severe or prolonged muscle injury, strenuous exercise, crush injuries, prolonged immobilization, seizures, or very high body temperatures. Other causes include certain medicines or drugs, alcohol and other toxic exposures, infections, metabolic disorders, and inherited muscle conditions. The condition may occur when muscle cells are damaged directly or when the blood supply or normal metabolism of muscle tissue is disrupted.
Sedentary Lifestyle
Risk Factors
Risk increases with severe physical exertion, especially when exercise is unusually intense or performed in hot conditions, traumatic muscle injury, prolonged immobilization, seizures, and extreme heat exposure. Certain medicines, recreational drugs, heavy alcohol use, infections, and metabolic or inherited muscle disorders can also increase risk. Dehydration may worsen the consequences of muscle injury and contribute to complications.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Diagnosis is based on symptoms, physical examination, and laboratory testing. A blood test measuring creatine kinase is commonly used to detect significant muscle breakdown and may be repeated to follow the condition. Blood tests also assess kidney function and electrolyte levels. Urine testing may show evidence of myoglobin-related muscle injury. Additional tests may be performed when an underlying drug exposure, infection, metabolic disorder, or inherited condition is suspected.
Prevention
Key Prevention Tips
Risk can be reduced by increasing strenuous exercise gradually, staying adequately hydrated, avoiding excessive heat exposure, and taking medicines only as prescribed
People should use appropriate safety measures during physically demanding work or activities and seek medical care after major muscle injury
Avoiding harmful drug or alcohol exposures can also reduce risk
Prompt evaluation of severe muscle pain, weakness, swelling, or unusually dark urine may help prevent serious complications
Prevention Guidance
Risk can be reduced by increasing strenuous exercise gradually, staying adequately hydrated, avoiding excessive heat exposure, and taking medicines only as prescribed. People should use appropriate safety measures during physically demanding work or activities and seek medical care after major muscle injury. Avoiding harmful drug or alcohol exposures can also reduce risk. Prompt evaluation of severe muscle pain, weakness, swelling, or unusually dark urine may help prevent serious complications.
Reminder: Prevention recommendations should be tailored to your personal health status and risk factors.
