We presume the term 'meat' means muscle in Urine. Normally urine will not contain muscle in it. There can't be muscles present in the urine. But myoglobin, a protein present in the muscle cells, can be found in the urine in cases of muscle destruction. Myoglobinuria is usually the result of rhabdomyolysis
or muscle destruction. Any process that interferes with the storage or use of energy by muscle cells can lead to myoglobinuria. The most common causes of myoglobinuria in adults are Alcohol and Drug abuse, usually in relation to muscle necrosis
from prolonged immobilization and pressure by the body weight. Prolonged ethanol consumption and seizure activity, similar to excessive physical activity, can produce an imbalance between muscle energy consumption and production, resulting in muscle destruction. In children and adolescents, the most common causes of rhabdomyolysis and myoglobinuria are viral myositis
, trauma, excessive exercise, drug overdose
, seizures, metabolic disorders, and connective tissue
disease and also seen in athletes. The appropriate hydration and drugs with frequent monitoring can help the person to come out of the situation.
