Muscle breakdown can occur due to several factors, including injury, trauma, overexertion, medications, or underlying health conditions. One such condition is rhabdomyolysis, where damaged skeletal muscles break down rapidly, releasing toxic components into the bloodstream, which can lead to kidney damage and even failure if left untreated. Rhabdomyolysis is often caused by high-intensity exercise, severe dehydration, medications, or substance use disorders. Another condition that results in muscle breakdown is muscle atrophy, which can be caused by disuse of muscles or neurogenic conditions. This leads to a decrease in muscle mass and strength. It is important to seek medical attention and treatment for muscle breakdown conditions to prevent further complications.

What You'll Learn
Rhabdomyolysis
When muscle is damaged, a protein called myoglobin is released into the bloodstream and filtered out of the body by the kidneys. Myoglobin breaks down into substances that can damage kidney cells, causing acute kidney injury and even kidney failure. Myoglobinuria, the presence of myoglobin in the urine, occurs when the level in plasma exceeds 0.5–1.5 mg/dL. Once plasma levels reach 100 mg/dL, the urine becomes visibly discoloured, turning a tea colour.
Other symptoms of rhabdomyolysis include muscle pain, tenderness, weakness, swelling of the affected muscles, vomiting, and confusion. Diagnosis is based on abnormal blood tests, with a focus on creatine kinase (CK) levels, a protein that muscles release when they break down. CK levels above 1000 U/L indicate rhabdomyolysis, and levels above 5000 U/L indicate a severe condition.
Treatment for rhabdomyolysis centres on preserving renal function, including vigorous rehydration with fluids containing bicarbonate, and in some cases, kidney dialysis.

Muscle atrophy
There are three main types of muscle atrophy: physiologic, pathologic, and neurogenic. Physiologic atrophy, also known as disuse atrophy, is caused by the lack of muscle use. This can be due to immobility, aging, malnutrition, medications, or injuries that require immobilization. Pathologic atrophy is associated with aging, starvation, and diseases such as Cushing's disease or hypothyroidism. Neurogenic atrophy is caused by nerve injuries or diseases, such as amyotrophic lateral sclerosis (ALS) or damage to the spinal cord.
The symptoms of muscle atrophy include a decrease in muscle mass, with one limb sometimes being smaller than the other. Individuals may also experience numbness, weakness, and tingling in their limbs. In some cases, muscle atrophy can lead to difficulty in performing physical tasks, such as standing from a seated position or walking. Atrophy of facial or throat muscles can cause difficulty in speaking or swallowing.
The treatment for muscle atrophy depends on the underlying cause but often includes exercise and improved nutrition. Physiologic atrophy can often be reversed with physical activity and a healthy diet. Neurogenic atrophy may require additional treatments such as physical therapy, ultrasound therapy, or surgery, depending on the severity and location of the atrophy. It is important to consult a healthcare professional for a proper diagnosis and treatment plan.
While muscle atrophy can have various causes and present different symptoms, it is important to address it promptly to prevent further muscle deterioration and maintain overall health. Early diagnosis and appropriate treatment are crucial for managing muscle atrophy effectively.

High-intensity exercise
Rhabdomyolysis can be caused by various factors, including injury, trauma, severe burns, electrocution, or crushing injuries. It can also be induced by certain medications, high body temperature, or heat stroke. Those who work outdoors or in hot conditions are at higher risk. The condition causes muscle fibres to break down, releasing chemicals such as myoglobin, creatine kinase, potassium ions, and phosphate ions into the bloodstream.
Myoglobin, a relative of hemoglobin, can be detected in urine tests, but these are not as accurate as blood tests. Creatine kinase (CK) levels in the blood are a more reliable indicator of rhabdomyolysis. CK is a protein released when muscles break down, and elevated CK levels confirm the diagnosis.
The consequences of muscle breakdown in rhabdomyolysis can lead to serious health issues. The release of myoglobin and other muscle breakdown products can cause acute kidney injury and worsen kidney function, leading to kidney failure. It can also disrupt the balance of electrolytes in the body, affecting the heart and other organs. If left untreated, rhabdomyolysis can be life-threatening.
Symptoms of rhabdomyolysis include muscle pain, weakness, vomiting, confusion, dark urine (tea-coloured), irregular heartbeat, and muscle swelling. If these symptoms occur after engaging in high-intensity exercise, it is crucial to seek medical attention promptly. Early diagnosis and treatment are critical for a successful outcome and to prevent further muscle damage or nerve injury.

Medication and substance use
Substance use disorder (SUD) is a mental health condition characterised by a problematic pattern of substance use that negatively affects an individual's health, well-being, and quality of life. SUD can range from mild to severe (addiction), and commonly involves substances such as alcohol, opioids, and marijuana. While the exact cause of SUD is not fully understood, research suggests that changes in the brain's reward system due to a substance's addictive potential play a crucial role. Social pressure, curiosity about substance effects, performance enhancement, and emotional escape are also factors that can contribute to the development of SUD.
Chronic alcohol use, a common aspect of SUD, can directly impact the muscular system. Alcohol interferes with the absorption of nutrients like calcium, increasing the risk for bone diseases. Additionally, the body's process of metabolising alcohol produces a toxic substance called acetaldehyde, which is linked to an elevated risk for various forms of cancer. Prolonged alcohol consumption can lead to conditions such as rhabdomyolysis, where muscle tissue breaks down, releasing toxins into the bloodstream. This condition can eventually result in kidney failure and compromise the entire muscular system.
The abuse of central nervous system stimulants, such as cocaine and methamphetamine, is another aspect of SUD that can affect the muscular system. These stimulants can compromise the functioning of the cardiovascular system and cause significant damage to the heart's muscle. Prolonged stimulant use may produce brain damage, further impacting the musculoskeletal system. Additionally, the use of inhalants through the inhalation of fumes from household items like aerosols, spray paints, and cleaners, can lead to brain damage and compromise the muscular system.
Anabolic steroid abuse is another form of substance misuse that can alter muscle growth and lead to muscle tears, ruptures, and infections. Chronic steroid use may damage the central nervous system and the cardiovascular system, increasing the risk of further damage to multiple organ systems. Additionally, the development of dental issues and skin abscesses associated with methamphetamine abuse can indirectly lead to diseases that compromise the muscular system.
The use of certain medications can also cause muscle breakdown and toxicity. Statin medications have been linked to rhabdomyolysis, especially when used in the context of diabetes or liver disease. Antipsychotic, antidepressant, and antiviral medications have also been implicated in muscle deterioration. It is important to recognise that drug-induced muscle toxicity can vary significantly between different drugs and even between patients taking the same medication.
