What is the cause of nasal congestion?

5 nasal cavity tumor leads to nasal congestion. Long tumors in the nasal cavity, whether benign or malignant, may block the nasal cavity and cause nasal congestion. If not treated in time, the tumor will continue to swell, and the benign tumor may press the nasal septum to make it deviate, thus blocking both sides of the nasal alar, destroying the surrounding normal tissue structure, causing it to fester or even die, leading to an increase in nasal secretions, thus accelerating and aggravating the degree of nasal congestion.

6 sleeping in the wrong position leads to nasal congestion. Many people like to sleep on their side, but sometimes they feel that sleeping on the right side will block their right nose and lying on the left side will block their left nose. The reason for this phenomenon is due to the gravity of blood. When lying on your side, the inferior turbinate is prone to congestion and swelling, which will cause a stuffy nose on one side, and the blood in the upper nasal congestion is relatively small, so it is unobstructed.

7 gum infection leads to nasal congestion. If the maxillary teeth are infected by bacteria, the bacteria will infect the sinuses through the bone structure, causing the sinuses to swell, thus causing nasal congestion. On the other hand, swelling of sinuses due to infection can also oppress the upper jaw, leading to toothache.
