What are causes of congestion?
Nasal congestion can be caused by anything that irritates or inflames the nasal tissues. Infections — such as colds, flu or sinusitis — and allergies are frequent causes of nasal congestion and runny nose. Sometimes a congested and runny nose can be caused by irritants such as tobacco smoke and car exhaust.
What causes congestion pathology?
Congestion is a localized increase of blood in a particular tissue due to poor venous outflow. Consequently, congestion is almost always due to some circulatory pathology in veins downstream of the congested area.
What does congestion in lungs mean?
When the bronchi in your lungs are exposed to a virus, they swell and fill with a thick fluid called mucus. This excess fluid constricts the airflow, making it difficult to breathe. Symptoms of chest congestion include: Hacking cough with clear, green, or dark yellow mucus.
What is mucosal hyperemia?
The arrival of more blood turns the mucosa redder (hyperemia) and causes it to swell. The greater volume of the mucosa creates a blockage in the nasal cavities, causing the sensation of stuffy nose.
What is the difference between hyperemia and congestion?
Hyperemia and Congestion. Hyperemia is an active process that is part of acute inflammation, whereas congestion is the passive process resulting from decreased outflow of venous blood, as occurs in congestive heart failure (Fig. 9-56).
What happens during congestion?
Nasal congestion or “stuffy nose” occurs when nasal and adjacent tissues and blood vessels become swollen with excess fluid, causing a “stuffy” plugged feeling. Nasal congestion may or may not include a nasal discharge or “runny nose.”
What is difference between congestion and hyperemia?
Is congestion caused by inflammation?
Nasal congestion is often a result of inflammation. When you’re sick, the blood vessels lining the nasal cavity become swollen and inflamed. This can cause nasal congestion. Nasal inflammation is often caused by the body’s response to what it identifies as a foreign agent.

What is mild hyperemia?
What is mild hyperemia? Hyperaemia (also hyperemia) is the increase of blood flow to different tissues in the body. Clinically, hyperaemia in tissues manifest as erythema (redness of the skin) because of the engorgement of vessels with oxygenated blood. Hyperaemia can also occur due to a fall in atmospheric pressure outside the body.
