Learn about pneumonia's signs, causes, and preventive measures. This guide covers risk factors, symptoms, diagnosis, and tips to avoid serious complications through vaccination and early treatment.

Pneumonia is a respiratory infection that inflames one or both lungs, specifically affecting the alveoli, the tiny air sacs responsible for oxygen exchange. It can be triggered by bacteria, viruses, or fungi, with bacteria being the primary cause in adults. The infection leads to the filling of alveoli with pus and fluid, impairing breathing.

Though anyone can contract pneumonia, certain groups are at a higher risk. Infants under age 2 and seniors over age 65 are especially susceptible. Individuals with chronic conditions such as asthma, diabetes, or heart disease also face increased vulnerability.

Potential complications include bacteria entering the bloodstream or severe breathing difficulties, often necessitating hospitalization and ventilator support.

Diagnosis involves physical exams, chest X-rays, blood tests, sputum analysis, and sometimes CT scans. Symptoms may include cough with mucus, fever, chest discomfort, and fatigue. Severity varies based on age and health status.

Preventative strategies encompass vaccination and annual flu inoculations, which help differentiate pneumonia symptoms from the flu. Prompt treatment with rest and medication improves recovery prospects and reduces serious risks.
