Experiencing dark red "Coca-Cola" urine is a significant indicator that a person should be referred for medical treatment. This particular symptom can suggest serious underlying issues such as rhabdomyolysis, a condition caused by the breakdown of muscle tissue that releases myoglobin into the bloodstream, leading to potential kidney damage. The coloration of the urine is a critical warning sign that demands immediate medical attention.

In contrast, feeling overly fatigued after workouts can be attributed to various factors such as insufficient recovery, inadequate nutrition, or just a challenging workout routine, but it does not inherently indicate a medical emergency. Visible changes in muscle definition are typically normal adaptations to exercise and are not a cause for concern. Lastly, the inability to increase weight lifted over time can stem from training plateaus or improper programming but does not necessarily warrant medical intervention. Therefore, the presence of dark red urine stands out as the key marker for seeking medical evaluation.
