What does nasal obstruction mean?
Nasal obstruction describes a situation in which breathing through the nose is made difficult or restricted. This means that air can no longer flow freely through the nasal passages, which may make breathing through the mouth necessary.
When breathing through the nose feels difficult
The nose plays an important role in breathing: it filters, warms, and moistens the air we breathe in before it reaches the lungs. When the airflow is blocked, however, this function is partly lost. This can feel very different from person to person, ranging from a slight feeling of pressure to the sensation of not being able to get enough air. Switching to mouth breathing is often the result.
This kind of obstruction can affect one or both sides of the nose. Sometimes it is only temporary, such as during a cold, but sometimes it is present all the time. Typical symptoms include a blocked nose, snoring at night, a dry mouth, or a reduced sense of smell. Headaches, difficulty concentrating, and a dry throat are also possible accompanying complaints.
What causes it?
Common causes of nasal obstruction include swelling of the nasal lining, as seen with colds or allergies. Anatomical features, such as a deviated nasal septum, can also block the airflow. Nasal polyps, which are benign growths on the nasal lining, or enlarged turbinates can play a role as well.
Less commonly, chronic inflammation, injuries, foreign objects, or even tumours can be behind the symptoms. In children, enlarged adenoids can be a reason why the nose feels constantly blocked. Sometimes long-term use of decongestant nasal sprays can also make things worse, because the nasal lining reacts to the active ingredients.
Is it dangerous?
Whether nasal obstruction is serious depends strongly on the cause and how severe it is. A short-term blocked nose during a cold is generally harmless and goes away on its own after a few days. However, if the obstruction lasts longer or if other symptoms appear, such as fever, severe pain, or bloody discharge, it is worth seeing a doctor.
Long-term problems with nasal breathing can significantly affect quality of life. People who struggle to breathe at night often sleep restlessly, snore, or wake up with a dry mouth. In children, chronic nasal obstruction can even affect development, including speech development and the growth of the upper jaw. The risk of respiratory infections also increases when the nose can no longer perform its natural filtering function.
What to do about ongoing symptoms?
If the nose is persistently blocked or breathing keeps feeling difficult, it is worth visiting an ear, nose, and throat (ENT) specialist. The nose will usually be examined first. Sometimes a simple look with a nasal speculum is enough, but sometimes further investigations such as nasal endoscopy are needed. If an allergy is suspected, specific tests can be carried out.
Treatment depends on the cause. For swelling of the nasal lining, decongestant nasal sprays can often help, though these should only be used for a short time. Allergies can be treated with specific medicines or desensitisation therapy. For anatomical changes such as a deviated septum or polyps, a surgical procedure can relieve symptoms. Sometimes nasal rinses or targeted moisturising of the nasal lining are enough to improve breathing.
What can help in everyday life?
There are some simple steps that can support nasal breathing. Keeping enough moisture in the air at home prevents the nasal lining from drying out. Airing rooms regularly, drinking plenty of fluids, and avoiding smoke or strong irritants also have a positive effect. With allergies, it helps to avoid triggers as much as possible.
At night in particular, sleeping with the head slightly raised can make breathing easier. Nasal rinses with saline solution clean the nasal passages and keep the lining moist. It is important not to use decongestant sprays on a long-term basis, as these can make symptoms worse over time.
When is medical help needed?
If nasal obstruction comes on suddenly and is very severe, accompanied by breathlessness, pain, or fever, medical advice should be sought quickly. If symptoms last longer than two to three weeks or keep coming back, a thorough assessment is a good idea. For children who are constantly breathing through their mouth, snoring, or sleeping poorly, an appointment with a GP or ENT specialist is recommended.
Early treatment can prevent symptoms from getting worse or causing further problems. In many cases, nasal breathing can be significantly improved with simple measures or targeted therapies.
