Why Eating Can Cause Nasal Congestion: ENT Issues - Otolaryngology

Nasal congestion occurs when eating?


Hello Dr.
Cheng, I do not have a history of nasal allergies, but I recently noticed that whenever I eat or drink, I often feel a lack of oxygen and need to inhale forcefully through my nose (due to nasal congestion).
This usually occurs on the left side and has been happening for several years.
I used to eat quickly and didn't notice it, but after slowing down my eating pace, I became aware of this issue.
When cleaning my nostrils, I feel that the left nasal cavity wall is more swollen compared to the right side.
Could this be the reason for my nasal congestion while eating? Do I need treatment? Wishing you peace.

Hello: It may be primarily related to a deviated septum or hypertrophy of the inferior turbinate or nasal polyps.
If persistent nasal congestion affects your daily life, it is advisable to seek medical evaluation.
Wishing you peace and good health.
Sincerely, Dr.
Jue-Yi Cheng, Director of the Department of Otolaryngology, Taoyuan Hospital, Ministry of Health and Welfare.

More Info


Eating can indeed lead to nasal congestion, and this phenomenon can be attributed to several underlying ENT (Ear, Nose, and Throat) issues. The symptoms you describe, such as feeling a lack of oxygen and needing to breathe forcefully through your nose while eating, suggest that there may be an anatomical or physiological reason for your nasal congestion during meals.

One common cause of nasal congestion while eating is the dysfunction of the soft palate. The soft palate is a muscular structure located at the back of the roof of the mouth, and it plays a crucial role in separating the nasal cavity from the oral cavity during swallowing. If the soft palate does not close properly, food or liquid can inadvertently enter the nasal cavity, leading to a sensation of nasal congestion or obstruction. This can also cause discomfort and the feeling of needing to clear your nose while eating.

Another potential cause is the presence of nasal polyps or hypertrophy of the inferior turbinates. These conditions can lead to chronic nasal obstruction, which may become more pronounced during activities such as eating, when the body is in a more upright position and the airflow dynamics change. If you notice that one side of your nasal cavity feels more swollen or congested than the other, it could indicate an underlying issue such as a deviated septum or localized inflammation.

Additionally, your symptoms could be related to gastroesophageal reflux disease (GERD). GERD can cause acid to flow back into the throat, leading to irritation and inflammation of the nasal passages. This can result in a sensation of nasal congestion, especially after eating. If you experience heartburn or regurgitation along with your nasal symptoms, it may be worthwhile to discuss this possibility with your healthcare provider.

Given that you have been experiencing these symptoms for several years, it is advisable to seek further evaluation from an ENT specialist. They may perform a nasal endoscopy to visualize the nasal passages and assess for any structural abnormalities, such as polyps or a deviated septum. Additionally, they may evaluate the function of your soft palate and assess for any signs of reflux that could be contributing to your symptoms.

In terms of treatment, if anatomical issues are identified, options may include medical management with nasal corticosteroids to reduce inflammation or surgical interventions to correct structural problems. If allergies or environmental factors are contributing to your symptoms, allergy testing and management may also be beneficial.

In summary, while eating can lead to nasal congestion due to various ENT issues, it is essential to identify the specific cause in your case. A thorough evaluation by an ENT specialist will help determine the best course of action to alleviate your symptoms and improve your quality of life. If you continue to experience significant discomfort or if your symptoms worsen, do not hesitate to seek medical attention.
