Which of the following best describes a disease?

• A. A temporary discomfort
• B. A minor illness
• C. An abnormal condition that impairs normal body function
• D. A healthy state

Answer: (C)

A disease is an abnormal condition that impairs normal body function. This means it goes beyond simple discomfort or a minor, temporary issue: it represents a disruption to how the body or mind typically operates, often with recognizable signs or symptoms and sometimes with a known cause. In practice, this distinction matters because a disease signals that treatment, precautions, or alterations to procedures may be needed to protect the person’s health. The other options describe things that don’t imply a pathological disruption of function: temporary discomfort is not necessarily a disease, a minor illness is not a precise definition and can be variable, and a healthy state is the opposite of a disease.
