Overview
Both pneumonia and bronchitis affect the respiratory system and can cause coughing, chest discomfort, and difficulty breathing. Bronchitis primarily affects the bronchial tubes causing inflammation, while pneumonia involves infection in the air sacs of the lungs and typically presents with more severe symptoms including high fever.
Disease Summaries
Pneumonia: This is a serious infection that causes inflammation of the air sacs in one or both lungs, which may fill with fluid or pus. The condition can range from mild to life-threatening, with symptoms including chest pain, difficulty breathing, fever, and cough with phlegm. While it can affect anyone, pneumonia is most serious in infants, older adults, and people with weakened immune systems.
Bronchitis: This condition involves inflammation of the bronchial tubes that carry air to and from the lungs, causing coughing with mucus, chest discomfort, and fatigue. The condition can be acute (lasting a few weeks and usually caused by viral infections) or chronic (lasting months to years and often related to smoking). People with bronchitis typically experience a persistent cough that may last several weeks, even after other symptoms have resolved.

Treatment Approaches
Pneumonia Treatment Approaches
Treatment includes antibiotics for bacterial pneumonia, antiviral medications for viral cases, and supportive care including rest and hydration. Over-the-counter medications can help manage fever and pain, while breathing exercises aid recovery. Hospitalization may be necessary for severe cases requiring oxygen therapy or IV medications.
Bronchitis Treatment Approaches
Treatment focuses on symptom relief since most cases are viral and resolve on their own. This includes rest, increased fluid intake, and over-the-counter medications for cough and inflammation. For chronic bronchitis, inhaled medications, pulmonary rehabilitation, and smoking cessation are key components of treatment.
