What is the primary characteristic of edema?

• A. Fatigue
• B. Swelling
• C. Weakness
• D. Itching

Answer: (B)

Edema is primarily characterized by swelling due to an accumulation of fluid in the body’s tissues. This condition can occur in various parts of the body, such as the legs, ankles, and feet, but can also affect the abdomen and other areas. The swelling results from factors like increased capillary permeability, venous obstruction, or changes in osmotic pressure, leading to an imbalance in fluid homeostasis. While fatigue, weakness, and itching can be symptoms related to other conditions, the hallmark of edema is undeniably the visible and palpable swelling, which directly reflects the underlying fluid retention. Therefore, swelling stands out as the defining characteristic of edema.
