What condition is characterized by inflammation of the appendix?

The condition characterized by inflammation of the appendix is indeed appendicitis. This occurs when the appendix becomes swollen and inflamed, often due to a blockage that causes bacteria to multiply inside the appendix, leading to infection. Symptoms typically include sharp pain in the lower right abdomen, fever, nausea, and sometimes vomiting. Early diagnosis and treatment are crucial, as untreated appendicitis can lead to serious complications such as rupture, which can result in peritonitis or sepsis.

Other conditions listed, such as heat exhaustion, anaphylactic shock, and asthma, pertain to different physiological issues and responses. Heat exhaustion is related to excessive loss of water and salts due to prolonged exposure to high temperatures. Anaphylactic shock is a severe, potentially life-threatening allergic reaction. Asthma is a chronic respiratory condition characterized by inflammation and constriction of the airways. Each of these conditions affects different systems of the body and presents with distinct symptoms, making them unrelated to appendicitis.
