What condition is caused by a lack of blood supply?

• A. Ischemia
• B. Laceration
• C. Melena
• D. Hypertension

Answer: (A)

Ischemia is a medical condition that occurs when there is a reduction or lack of blood supply to a specific area of the body. This diminished blood flow can lead to a shortage of oxygen and nutrients that are essential for cellular metabolism and overall function, which can result in tissue damage or dysfunction if not addressed promptly. In cases of ischemia, the affected tissues may experience symptoms such as pain (for example, angina in the heart), weakness, or even necrosis if the blood supply is critically compromised. Understanding ischemia is crucial in fields such as cardiology and emergency medicine, where timely intervention can prevent further complications. Other conditions mentioned, such as laceration, relate to physical injury rather than blood supply, while melena refers to dark, tarry stools typically resulting from gastrointestinal bleeding. Hypertension, or high blood pressure, is a condition related to the force of blood against vessel walls and does not imply a lack of blood supply.
