Muscle death, or rhabdomyolysis, is a serious condition caused by direct or indirect muscle injury. It occurs when muscle fibres die and release harmful substances into the bloodstream, which can lead to kidney damage or failure and even death if left untreated. Rhabdomyolysis can be caused by various factors, including extreme muscle strain, high body temperature, seizures, metabolic disorders, muscle diseases, ageing, starvation, immobilization, and intense or prolonged exercise, particularly in hot conditions. Symptoms of rhabdomyolysis include muscle pain, weakness, vomiting, confusion, and tea-coloured urine. Treatment focuses on managing the patient's airway, breathing, and circulation, as well as preserving renal function to prevent acute kidney injury.

What You'll Learn
Rhabdomyolysis
Any form of muscle damage of sufficient severity can cause rhabdomyolysis. Recurrent or episodic rhabdomyolysis is often due to intrinsic muscle enzyme deficiencies, which are usually inherited and may appear during childhood. Many structural muscle diseases feature episodes of rhabdomyolysis triggered by exercise, general anaesthesia, or other causes. Inherited muscle disorders and infections are the most common causes of rhabdomyolysis in children.
The symptoms of rhabdomyolysis vary in severity and depend on the presence and degree of kidney failure. Mild forms may not cause any muscle symptoms, and diagnosis is based on abnormal blood tests in the context of other problems. More severe cases are characterised by muscle pain, tenderness, weakness, and swelling of the affected muscles. Urine may also become discoloured, taking on a reddish-brown or tea-like hue.
Treatment for rhabdomyolysis is centred on preserving renal function and managing the ABCs (airway, breathing, and circulation). Vigorous rehydration is often necessary, and fluids containing bicarbonate may be administered intravenously to help prevent kidney damage. In some cases, kidney dialysis may be required.
To prevent rhabdomyolysis, it is important to avoid potential triggers such as certain medications or drugs, extreme exercise, and exposure to high temperatures. When starting resistance training, it is crucial to start slowly and gradually increase the load to prevent muscle breakdown.

Causes of muscle death
Muscle death, or rhabdomyolysis, is a serious condition that occurs when muscle fibres die and release their contents into the bloodstream. This can lead to serious complications such as kidney failure and even death if left untreated.
There are several causes of muscle death, including:
Extreme muscle strain
Those who exercise regularly, particularly elite athletes, are at risk of muscle death due to extreme muscle strain. This risk is heightened for those with a higher body mass index (BMI) and greater muscle mass.
Medication and substance use
The use of certain medications, such as antipsychotics, statins, and prescription drugs to lower cholesterol, can increase the risk of muscle death. Additionally, the use of illegal drugs such as cocaine, amphetamines, and heroin has been linked to muscle death.
Extreme temperatures
Working or exercising in hot conditions can contribute to muscle death. Those who work outdoors or in high temperatures, including construction workers, military service members, farmers, firefighters, and first responders, are at a higher risk.
Medical conditions
Underlying muscle conditions, often hereditary, can make individuals more prone to muscle death. Genetic muscle diseases, metabolic disorders, and diseases of the muscles (myopathy) can all contribute to muscle breakdown.
Trauma and injury
Crush injuries, such as those sustained in accidents or building collapses, can lead to muscle death. Intense or prolonged exercise can also cause muscle damage, particularly when performed in hot conditions.
Other factors
Other factors that can contribute to muscle death include seizures, muscle tremors, severe dehydration, lengthy surgical procedures, and muscle immobilization. Aging, starvation, inflammation, and cancer can also play a role in muscle atrophy and death.

Symptoms of muscle death
Muscle death, or rhabdomyolysis, is a serious condition caused by a direct or indirect muscle injury. It occurs when muscle fibres die and release their contents into the bloodstream. This can lead to serious complications such as renal (kidney) failure, which can be life-threatening. The symptoms of rhabdomyolysis vary depending on its severity and whether kidney failure develops.
Milder forms of rhabdomyolysis may not cause any muscle symptoms, and diagnosis is based on abnormal blood tests. More severe cases are characterised by muscle pain, tenderness, weakness, and swelling of the affected muscles. If the swelling is rapid, as in the case of a crush injury, the movement of fluid from the bloodstream into the damaged muscle may cause low blood pressure and shock. Other symptoms may include nausea, vomiting, confusion, coma, or abnormal heart rate and rhythm.
The "classic triad" of rhabdomyolysis symptoms includes muscle pain in the shoulders, thighs, or lower back. Symptoms usually develop one to three days after a muscle injury, though some may not notice muscle soreness. Other symptoms include muscle stiffness and a change in urine colour, such as dark urine that is brown, red, or tea-coloured.
In some cases, muscle death may be a result of sarcopenia, the gradual loss of muscle mass, strength, and function commonly associated with ageing. Symptoms of sarcopenia include muscle weakness, loss of stamina, difficulty performing daily activities, walking slowly, trouble climbing stairs, poor balance, and falls.
If you experience any of these symptoms, it is important to seek medical attention.

Treatment for muscle death
Muscle death, or rhabdomyolysis, is a serious condition caused by direct or indirect muscle injury, resulting in muscle tissue breaking down and releasing chemicals, including a protein called myoglobin, into the bloodstream. This can lead to serious complications such as kidney failure and even death. However, early treatment often results in a good outcome.
Hospitalisation and Monitoring
If you have rhabdomyolysis, you will likely be admitted to the hospital to receive treatment and monitoring. In some severe cases, you may need to be admitted to the intensive care unit (ICU) for close observation.
Intravenous (IV) Fluids
Treatment for rhabdomyolysis often involves receiving fluids and electrolytes intravenously (through a vein). These IV fluids help to flush toxins from your system, maintain urine production, and prevent kidney failure. Hospitalisation may be required for a few days to receive these fluids.
Dialysis
In cases of severe kidney damage, dialysis may be necessary. This process involves extracting blood, removing toxins, and returning the filtered blood to the body. Dialysis can help the kidneys filter waste products while they recover.
Surgery
In certain situations, a surgical procedure called fasciotomy may be required to ease tension, pressure, and loss of circulation caused by compartment syndrome. Compartment syndrome is a serious condition characterised by excessive pressure buildup inside an enclosed muscle space, which can lead to muscle death or nerve damage.
Medication Adjustment
If rhabdomyolysis is related to medication or drug use, adjustments need to be made. This may involve stopping the use of the medication or replacing it with an alternative.
Physical Therapy
After an initial period of rest, physical therapy can help strengthen muscles and aid in recovery. It is important to follow your doctor's advice regarding limitations on diet and activity, gradually increasing physical activity as advised.
Underlying Conditions
If rhabdomyolysis is associated with an underlying medical condition, such as diabetes or a thyroid disorder, appropriate treatment for that condition will be necessary.
Prevention:
While not all cases of rhabdomyolysis can be prevented, certain measures can reduce the risk, especially in the context of exercise-induced rhabdomyolysis:
- Start exercise programs slowly and gradually increase intensity.
- Stay hydrated and avoid overheating.
- Listen to your body and avoid overworking or pushing beyond safe limits.
- Seek advice from exercise professionals before starting resistance training.

Prevention of muscle death
Muscle death, or rhabdomyolysis, is a serious condition caused by a direct or indirect muscle injury. It occurs when muscle fibres die and release their contents, including a protein called myoglobin, into the bloodstream. This can lead to kidney damage and even kidney failure. While rhabdomyolysis can be life-threatening, early treatment often brings a good outcome.
To prevent muscle death, it is important to understand the risk factors and causes, which can be categorised as physiological, pathological, and traumatic.
Physiological causes of muscle death include ageing, which is the most common cause of sarcopenia, or muscle loss. Sarcopenia is characterised by a gradual loss of muscle mass, strength, and function, often affecting the elderly. While ageing is a natural process that cannot be prevented, there are ways to slow down muscle loss. Maintaining a healthy diet with adequate protein intake is important, as the body's ability to produce muscle-building proteins decreases with age. Aim for 20 to 35 grams of high-quality protein in each meal. Additionally, staying physically active, especially with exercises like resistance training, can help slow down muscle atrophy.
Pathological causes of muscle death include cachexia, metabolic disorders such as diabetic ketoacidosis, congenital muscle enzyme deficiency, and Duchenne's muscular dystrophy. Preventing muscle death in these cases may involve appropriate medical treatment for the underlying condition. For example, in the case of diabetic ketoacidosis, managing blood sugar levels and seeking medical treatment can help prevent muscle breakdown.
Traumatic causes of muscle death include extreme muscle strain, especially in individuals with a high body mass index (BMI) who exercise regularly. Starting an exercise program slowly and listening to your body are crucial to preventing rhabdomyolysis. When beginning resistance training, it is recommended to start with lower training loads of 60-70% for 8 to 12 repetitions and gradually increase the load. Staying hydrated and avoiding overheating are also important preventive measures.
Additionally, certain medications, such as antipsychotics and statins, especially in high doses, can increase the risk of muscle death. If medication is a contributing factor, its use may need to be stopped or replaced with an alternative under medical supervision.
In summary, preventing muscle death involves a combination of healthy lifestyle choices, such as proper nutrition and exercise, as well as careful management of any underlying medical conditions or risk factors that may contribute to muscle breakdown.
