Lungs, congested

Christopher Hobbs:

“Congestion of the lungs can be due to excessive mucus production. Congestion can also result from a previous infection or inflammation in the lung.”

Etiologic and Other Factors Leading to Congested Lungs:

1. Infections: Common causes include viral or bacterial infections like the flu, pneumonia, or bronchitis.
2. Allergies: Exposure to allergens (dust, pollen, or mold) can inflame airways and cause congestion.
3. Chronic Conditions: Conditions such as asthma, chronic obstructive pulmonary disease (COPD), or heart failure can result in fluid or mucus buildup in the lungs.
4. Environmental Irritants: Smoking, pollution, or chemical exposure can damage lung tissues and cause congestion.

When to Seek Professional Help:
Look out for these red flags:

• Severe shortness of breath or difficulty breathing.
• Chest pain, especially if it radiates to the jaw, arm, or back.
• Persistent or worsening symptoms despite home treatment.
• High fever (e.g., above 102°F or 39°C) or chills.
• Coughing up blood or large amounts of discolored mucus.
• Symptoms of confusion, fatigue, or fainting (possible oxygen deficiency).
