Stuffy nose, difficulty breathing through the nose, a feeling of pressure or a "full nose." Nasal congestion is a very common symptom, especially during the colder months, but it can have different causes and should not always be treated in the same way.
From a simple cold to allergic rhinitis, sinusitis, or exposure to very dry environments, understanding the source of the congestion is the first step in choosing the best way to relieve it.
What is nasal congestion?
Nasal congestion occurs when the tissues lining the inside of the nose become inflamed and enlarged, making it difficult for air to pass through.
This inflammation may be accompanied by other symptoms, such as:
- runny nose;
- sneezing;
- Itchy nose;
- a feeling of pressure in the face;
- headache;
- decreased sense of smell;
- Thicker nasal secretions.
The cause of the congestion is important because an obstruction caused by a cold is not necessarily treated in the same way as an obstruction associated with allergic rhinitis.
What are the most frequent causes?
Colds and respiratory infections
During a cold, the nasal mucosa becomes inflamed and produces more secretions, causing the well-known "stuffy nose".
In these cases, congestion usually occurs along with other symptoms, such as runny nose, sneezing, sore throat, cough, or general malaise.
Allergic rhinitis
In allergic rhinitis, congestion can appear after contact with allergens such as pollen, dust mites, or pet dander .
It is frequently associated with repeated sneezing, itchy nose, and watery eyes. When symptoms are persistent, nasal corticosteroids are one of the main therapeutic options for allergic rhinitis.
Sinusitis
Inflammation of the paranasal sinuses can cause congestion, nasal discharge, a feeling of pressure or pain in the face, and sometimes a reduction in the sense of smell.
Not all sinus infections require antibiotics. In most cases, evaluating the symptoms and their progression is essential to determine the appropriate approach.
Dry air and environmental factors
Environments with heating, air conditioning, smoke, or other irritants can contribute to dryness and irritation of the nasal mucosa, favoring the sensation of a stuffy nose.
How to relieve nasal congestion?
1. Wash your nose with saline solution.
Nasal hygiene with saline solutions can help remove secretions, allergens, and irritating particles, contributing to better nasal hygiene.
It can be particularly useful when there is a lot of mucus or during episodes of rhinitis.
When using nasal irrigation solutions, it is important to follow the product instructions and use water that is appropriate for this purpose.
2. Stay well hydrated.
Drinking fluids throughout the day helps keep secretions thinner and can make them easier to eliminate.
3. Control the humidity of the environment.
An excessively dry environment can worsen irritation of the nasal mucosa. Ventilating the house and avoiding excessively high temperatures can help maintain a more comfortable environment.
4. Nasal decongestants: use with caution.
Nasal decongestants, such as xylometazoline or oxymetazoline , provide a temporary reduction in congestion by decreasing swelling of the nasal mucosa.
They can provide quick relief, but should not be used for extended periods . Excessive use can cause the so-called rebound effect or rhinitis medicamentosa: when the effect wears off, the nose becomes congested again, and a cycle of increasingly frequent use may develop.
Therefore, it is essential to respect the duration of use indicated in the information leaflet or by the healthcare professional. Depending on the medication, this use is usually limited to a few days.
More decongestant doesn't necessarily mean better results.
What if the congestion is caused by allergies?
When allergic rhinitis is present, using only a decongestant may temporarily relieve a stuffy nose, but it does not treat the underlying inflammation.
Depending on the symptoms and their intensity, antihistamines and/or nasal sprays may be recommended, particularly nasal corticosteroids, which have an anti-inflammatory action and are especially effective in controlling congestion associated with allergic rhinitis.
If symptoms are recurring, it is important to try to identify the triggering factors and seek medical or pharmaceutical advice.
Nasal strips: can they help?
Nasal strips work differently from medications. When applied to the outside of the nose, they exert a mechanical action that can help to slightly open the nostrils.
They can be especially useful when there is difficulty breathing through the nose at night or during exercise.
However, they do not treat the inflammation or the cause of the congestion . Therefore, they can be seen as a complementary solution and not as a substitute for appropriate treatment when there is an underlying disease.
When should we seek medical advice?
Occasional nasal congestion associated with a cold is usually not a cause for concern. However, it is advisable to seek professional evaluation when:
- The congestion is persistent or recurrent;
- There is predominantly obstruction in only one nostril;
- There are frequent nosebleeds;
- There is intense facial pain or swelling;
- Significant changes in the sense of smell occur;
- The symptoms are very intense or are getting worse;
- There is significant difficulty breathing;
- The congestion persists despite the usual measures.
Persistent, one-sided nasal obstruction, especially when accompanied by bleeding, crusting, or pain, warrants medical evaluation.
In summary
A stuffy nose can have many causes and doesn't always require a decongestant .
Nasal irrigation with saline solution, hydration, and reducing irritants can be simple and helpful measures. When medication is necessary, the choice should take into account the cause of the congestion and the individual profile of each person.
And there's one particularly important rule: nasal decongestants should only be used for the recommended period . Prolonged use can end up causing exactly the problem it was intended to solve: more nasal congestion.
