What does a suffix of -pathy generally refer to in terms of health science?

  1. A study of diseases

  2. A specific visual condition

  3. A disease or disorder

  4. Measurement of health

The correct answer is: A disease or disorder

The suffix -pathy is commonly used in medical terminology to denote a disease or disorder. It derives from the Greek word "pathos," which means suffering or disease. Therefore, when this suffix is attached to a root word, it creates terms that indicate various types of diseases or health conditions, such as "neuropathy" (disease of the nerves) or "cardiomyopathy" (disease of the heart muscle). This understanding of -pathy aligns with the terminology used in health science, making the interpretation of the suffix as indicating a disease or disorder both accurate and relevant in a medical context. The other options refer to related but distinct concepts in health sciences, such as the study of diseases, specific conditions, or measurement, but do not capture the primary meaning of the suffix itself.
