Constant Blocked Nose But No Cold

Constant Blocked Nose But No Cold:

The feeling of suffering from a blocked nose could be really irritating; and more irritating could be the feeling of knowing that it is not cold but something else! Constant blocked nose is not only irritating or unpleasant, but it can be also hard to know the best possible way to cope up with the condition or tackle the constant blocked nose issue.

Now, let us come straight down to our topic, and that is “constant blocked nose but no cold.” It is true that most of us have experienced a blocked nose at some point or the other; and it is not always the cold that might be causing a constant blocked nose. There are many causes behind a constant blocked nose. So, here let us spend some time in knowing about some of those causes and seek the essential medical help to find the most appropriate and effective solution to the problem. Let us take a deeper look on these causes.

Allergic Rhinitis Causing Constant Blocked Nose:

Allergic rhinitis is an allergic reaction that occurs because of the air-borne particles like, pollen, dust mites, pet danders and several other allergens. This condition can result in a blocked nose in the short term, or much longer (in case you are surrounded by the allergen on a constant or regular basis, such as during the season of hay fever).

You must check with your doctor to know if you are experiencing a constant blocked nose because of allergic rhinitis and also try to keep away from the allergens.

Nasal Polyps Can Result In Constant Blocked Nose:

There is one more reason why you might be having constant blocked nose but no cold. Nasal polyps is in fact one of the most common causes of a constant and long-term blocked nose. These nasal polyps are small growths of tissues in the nasal passage that can actually obstruct the air flow. You can possibly get nasal polyps if you generally suffer from chronic condition of allergic rhinitis.

Though polyps by themselves are not harmful, it is very rare that your constant blocked nose will be able of clear off until the nasal polyps have reduced their size or have been removed by any means.

Food Intolerance Can Cause Constant Blocked Nose:

An intolerance to the food can cause inflammation of the mucous membranes, like those in the nasal passage. Dairy and gluten are two of the most common dietary or food intolerances.

Constant Blocked Nose Caused Due To Deviated Nasal Septum:

Constant blocked nose can also be due to a deviated nasal septum. The cartilage that sits between the two nostrils of the nose is known as the nasal septum. Ideally, this nasal septum divides the nose directly down the centre. However, in some people this septum lies off to the side and this in turn can make one of your nostrils feel more blocked than the other one, which happens because the flow of air is reduced down the smaller nostril. Moreover, it can be really hard for the mucus to drain through the smaller nostril.

Sinus Infection:

Still wondering what else could cause a constant blocked nose but no cold? Sinus infection could be one more reason for this. Viral infections are in fact one of the most frequent causes of unpleasant irritation in the nose, and this makes the tissues inflamed and swollen in the nose. There are several symptoms (such as reduced sense of smell, headache, and pain in the face) of a sinus infection that resembles the symptoms of cold or flu. A chronic sinus infection can last for more than 12 weeks and this is the reason why you need to seek appropriate medical assistance. However, keep it noted that not everyone of us would require antibiotics or medications; however you must check out with your doctor.

Respiratory Syncytial Virus Or RSV Causing A Constant Blocked Nose:

Respiratory syncytial virus or RSV is the virus that is responsible for causing infections of the lungs as well as the respiratory tract. It is very much common that most children have been infected with RSV by their age of 2. This virus can also cause infections in adults. However, the symptoms are mild and similar to the common cold, in case of adults and healthy children. Congestion, runny nose, dry cough, sore throat, mild fever and headache are some common symptoms of Respiratory syncytial virus infection.
In some people, especially older adults, infants, premature babies, and adults with lung or heart diseases, or someone with a weak immune system; the symptoms of RSV could be very severe. In severe cases, RSV can spread to your lower respiratory tract, leading to bronchiolitis or pneumonia.

Obstructions In The Nose (Especially In Children) Can Cause Constant Blocked Nose:

It is not very common among adult, however, children, especially kids have a usual habit of putting any random objects into their nose and into their ears too. If your child has been complaining about a constant blocked nose for a while, it is essential for you to have a check in their nose and also have a check with your doctor.

An Increased Level Of Oestrogen May Cause Constant Blocked Nose:

This can be really irritating. This type of constant blocked nose might also be accompanied by itchy nose and continuous sneezing, and thus it might feel as if you are developing a cold; though it might not be true.

So, what could be the reason behind it? It is thought to be because of in increases levels of the oestrogen or the female hormone during pregnancy, which affects the mucous membranes, and thus making them more susceptible to get swollen. This symptom generally clears off after childbirth, i.e. once the oestrogen hormone levels have readjusted.
