What does pallor refer to in medical terms?

Pallor in medical terminology specifically refers to an abnormal lack of color in the skin, resulting in a pale appearance. This can be due to various factors such as reduced blood flow, anemia, or other underlying health conditions. Recognizing pallor is important in clinical settings as it may indicate serious medical issues that require further evaluation and potential treatment. The other choices correspond to different skin color changes: redness typically points to inflammation or increased blood flow; yellowing, known as jaundice, suggests liver issues; and darkening of the skin can result from conditions like hyperpigmentation. Thus, recognizing pallor as pale skin is crucial for understanding and assessing patient health.
