Constant runny nose: causes and treatment

Published: Last Updated on

If the nose works appropriately, we should not remember that it is there, but it is not what happens to many. Inflammation, lack of proper air intake, permanent secretions … are just some of the problems in the nose. A constant runny nose is one of them and can be due to multiple issues, such as: allergy, exposure to toxins, or infections.

Next, in this FastlyHealarticle, you will find all the information about constant nasal drip: causes and treatment, to know the reasons for these permanent nasal secretions and how to treat them.

Nasal allergy

An allergy or allergic rhinitis is one of the most common causes of a constant runny nose without a cold, transparent in color. It is an exaggerated reaction of your body to some substance in the environment or food. Usually, this constant runny nose is accompanied by other symptoms such as:

  • Itching in the nose.
  • Stuffy nose.
  • Sneezing
  • Feeling that not enough air is entering through the nose (from both orifices or one).


When a person has that predisposition, habits are essential. You can prevent the appearance of these symptoms by modifying your diet. Avoiding excess processed foods, refined flour and sugar, and dairy will help reduce symptoms as they are one of the biggest producers of mucus.

Another useful preventive measure is keeping your nose clean. In its absence, you can perform nasal washes with water with sea salt, seawater, or hypertonic physiological solution.

In addition, some drugs help reduce your body’s response to allergens: antihistamines and corticosteroids. It is advisable not to abuse them because, like all medications, they have adverse effects that are sometimes not immediately noticeable over the years.

There are also nasal sprays with low absorption corticosteroids that can be used to reduce inflammation and thus reduce constant runny noses.

The following recommendations can also help you:

  • Avoid sudden temperature changes.
  • Do not expose yourself to the sun for a long time when congested.
  • Do not stay long in environments that abuse heating/air conditioning.

When the secretions are no longer clear but turn green, yellowish, or brownish, you may be suffering from a nose and sinus infection.

The constant runny nose is often accompanied by other symptoms such as:

  • Headache.
  • You feel like you have a stuffy nose.
  • Mucus in the throat
  • You have no smell/taste, or it is severely impaired.
  • Sometimes fever or persistent cough may also appear, especially at night.


The first thing is to clean the nose. If it is ventilated, if air flows through it, it will heal quickly. Therefore, it is critical to perform nasal washes correctly. You can see how to do them in: How to do a nasal wash.

Your doctor may prescribe antibiotics, antihistamines, and corticosteroids (as appropriate) for this constant runny nose. For your part, you can help yourself by having a healthy diet rich in fruits and vegetables, water, and whole grains. Avoiding processed, gluten, and dairy will benefit your health.

Rhinitis vasomotor

We all suffer from this condition, called vasomotor rhinitis, at some time. You can constantly run your nose from:

  • Cold environment.
  • Excessive heat
  • Ingestion of spicy food.


You will be less predisposed to suffering from vasomotor rhinitis and, therefore, constant runny nose if you cover your nose in extreme climates or with conditioners with wildly excessive temperatures. They can also help improve your state that your diet is healthier.

Exposure to toxics

If you are permanently exposed to toxic vapor such as smoke or vehicular pollution, your nose may react accordingly, generating a constant runny nose to try to clean the nose.

A poison you may not consider as such is tobacco, and it is a fundamental cause of rhinitis and nasal inflammation. There is a bigger problem: continuous exposure to these types of products can also cause you to develop lung diseases.


In these cases, the most important thing is to prevent:

  • If you smoke, you should stop. Learn more in Effects of tobacco on health.
  • When moving in environments with excessive toxic fumes, you should wear protection as the long-term consequences can be seriously damaging.
  • A good practice is to perform nasal washes when you return home to remove the toxins that may remain in the nostrils.

Medications for nasal congestion

Long-term use of decongestant drugs produces a rebound effect. On the one hand, they reduce inflammation by causing less blood to reach the nostrils, which will give you a sensation of a straightforward but short-lived nose.

The time that this “decongestant” effect lasts will be less and less because the nose will become inflamed again. With this type of medication, you are not reducing inflammation. You are only lowering circulation in the area.

A tricky issue in those cases is that prolonged use can lead to damage to the elastic fibers present in the nose. These allow the ventilation to open or close. If you are damaged, they will no longer allow the typical air passage, but you will feel your nose with a permanent blockage.


You should stop using this type of decongestant drops or creams that produce this effect. You can turn to an ENT specialist to help you change the drug for another more effective and less harmful treatment for your health.

Rhinitis in pregnancy

Some pregnant women may experience increased nasal congestion and constant runny nose during pregnancy. In the case of rhinitis during pregnancy, there will be clear secretions and nasal obstruction, especially when lying down.


If this is your case, you can clean your nose daily with:

  • Seawater.
  • Sea saltwater.
  • Hypertonic physiological solution.

It can also help you pay more attention to your diet and avoid those foods with gluten, spicy, or processed foods that can cause nasal congestion.

Histamine excess

The circulating histamine will increase when your body cannot adequately transform the histamine present in some foods (such as red wine, preserves, chocolate, or aged cheeses).

In those cases, you may experience a wide variety of symptoms, including:

  • Nasal congestion, constant runny nose, and rhinitis.
  • Redness of the face.
  • Migraines
  • Asthma.
  • Joint pain


If you think this is your case, it is advisable to see your doctor confirm that it is the cause of your constant runny nose.

In addition, you must avoid the foods that cause you this discomfort. Sometimes an antihistamine drug can help, but it does not mean that there will be less histamine in your body for it, only that it will not be able to work. It does not solve the problem. It will only cover the symptom.
