The American Society of Anesthesiologists (ASA) established a physical status classification system in 1963 to assess a patient's overall health before surgery [1]. Understanding **what is a class 2 patient** involves recognizing an individual with a mild, non-limiting systemic disease, which helps healthcare professionals manage risks.

Across the medical field, conditions are systematically categorized to ensure consistent evaluation and treatment planning. A critical aspect of this process involves defining **what are the four levels of severity** to help prioritize patient care and allocate resources effectively.

According to the World Health Organization (WHO), non-communicable diseases kill 41 million people each year, highlighting the importance of proper disease classification to understand public health. But beyond this, a simpler model helps clarify the fundamental **what are the 7 categories of diseases** that affect the human body, providing a foundational understanding for health education.

Though often misspelled as the Golligers classification, the correct name for this system is the Goligher classification. A medical classification system for hemorrhoidal disease is widely used by clinicians to assess the severity of internal hemorrhoids, primarily based on the degree of prolapse.
