Catarrh, often referred to as postnasal drip, is characterized by an excessive build-up of mucus in the nasal passages or throat. This condition can be triggered by a variety of factors including infections, allergies, and environmental irritants.

Effective management involves a combination of treatments ranging from home remedies to professional medical advice.


What is Catarrh?

Catarrh, often referred to as postnasal drip, is a common medical condition characterized by an excessive build-up of mucus in the nasal passages or the throat. This phenomenon occurs when the mucus glands in the nose and throat produce a higher volume of mucus than usual, which can lead to discomfort and irritation.

Mucus itself is not harmful; in fact, it plays a crucial role in the human body. It acts as a protective layer, trapping dust, viruses, and bacteria that you might breathe in, thereby preventing them from entering your lungs and causing infections. Under normal circumstances, this mucus is unnoticeable because it mixes with saliva and drips harmlessly down the back of your throat, where it is swallowed. However, when the body produces an excess, it becomes more noticeable and can cause the symptoms associated with catarrh.

Symptoms of Catarrh

Recognizing the symptoms of catarrh is the first step towards managing this uncomfortable condition.

Here is a list of the most common symptoms associated with catarrh:

  • Persistent cough: Often gets worse at night, affecting sleep quality.
  • A constant need to clear the throat: Due to the sensation of mucus trickling down the back of the throat.
  • Blocked or stuffy nose: Which may alternate between being blocked and suddenly running.
  • Sore throat: Can occur if the throat is irritated by frequent clearing.
  • Pressure in the sinuses or face: Especially around the forehead, cheeks, and eyes.
  • Reduced sense of smell and taste: Due to blockage in the nasal passages.
  • Hoarseness or a muffled voice: As a result of throat irritation.

If you're experiencing these symptoms and they're affecting your daily life, it might be helpful to use the Symptom Checker tool. This interactive tool can help you assess your symptoms and determine whether you might be experiencing catarrh or another related condition.

Causes of Catarrh

Understanding what causes catarrh can be pivotal in managing and preventing it effectively. The causes of catarrh can be broadly categorized into several groups:


Catarrh is commonly triggered by viral infections such as the common cold or the flu. Data based on the National Health Interview Survey of the National Center for Health Statistics show that the common cold annually causes 35.6 acute illnesses per 100 persons.

These viruses irritate the nasal and throat linings, leading to increased mucus production.


Allergic reactions are also a frequent cause of catarrh. Allergens such as pollen, dust mites, pet dander, or molds can trigger the body's immune response, resulting in the production of excess mucus as the body attempts to flush out these perceived threats.

Environmental Factors

Environmental irritants like smoke, pollution, and chemical fumes can cause or exacerbate catarrh. Changes in weather, especially cold and damp conditions, can also trigger or worsen the symptoms.

Other Medical Conditions

Medical conditions such as sinusitis, nasal polyps, or gastroesophageal reflux disease (GERD) can lead to chronic catarrh. In sinusitis, inflammation of the sinuses leads to sinus infections which contribute to continuous mucus production. Nasal polyps are growths in the nasal passage that can obstruct the airflow and mucus drainage, exacerbating catarrh symptoms.

Diagnosing Catarrh

Diagnosing catarrh involves a few systematic steps to understand the underlying causes and to rule out other conditions that might mimic its symptoms.

Here's a step-by-step guide on how catarrh is typically diagnosed:

  1. Medical History: The first step is often a detailed discussion of your medical history. Your doctor will ask about the symptoms you are experiencing, their duration, and any patterns you have noticed. This also includes any history of allergies or previous sinus issues.
  2. Physical Examination: The doctor may perform a physical examination, especially looking at the nasal passages, to check for signs of inflammation or blockage. This might involve using a lighted instrument to look into your nose and throat.
  3. Allergy Tests: If allergies are suspected to be a cause of your catarrh, you might be referred for allergy testing. This can help pinpoint specific allergens that you are reacting to.
  4. Imaging Tests: In cases where chronic catarrh is suspected or if conditions like sinusitis or nasal polyps are possible, your doctor may order imaging tests like an X-ray, CT scan, or MRI to look at your sinuses and nasal area more closely.
  5. Referral to a Specialist: If initial tests are inconclusive, or if your catarrh persists despite treatment, you might be referred to an ENT (ear, nose, and throat) specialist for further evaluation.

Treatment Options

Treating catarrh effectively often depends on the underlying cause, but there are several options available that can help alleviate symptoms or manage the condition.

Home Remedies

Home remedies can be very effective for relieving the symptoms of catarrh, especially in mild cases:

  • Stay Hydrated: Drinking plenty of fluids helps thin the mucus, making it easier to expel.
  • Steam Inhalation: Breathing in steam from a hot bath or shower, or from a bowl of hot water, can help loosen the mucus in the nasal passages and throat.
  • Warm Salt Water Gargle: Gargling with warm salt water can soothe a sore throat and may help clear mucus from the back of the throat.
  • Elevate Your Head: Sleeping with your head elevated can prevent mucus from accumulating in the back of the throat during the night.

Over-the-Counter Treatments

For those whose symptoms require a bit more intervention, over-the-counter (OTC) treatments can be helpful:

  • Nasal Saline Sprays: These help to moisturize nasal passages and thin the mucus, which can reduce the feeling of congestion.
  • Nasal Decongestant Sprays: These should be used for only a few days as they can cause rebound congestion if used too long.
  • Mucus-Thinning Medications: Products containing guaifenesin can thin the mucus and make it easier to clear.

Prescription Medications

In cases where catarrh is severe or chronic, a doctor might prescribe stronger treatments:

  • Nasal Corticosteroids: These sprays help reduce inflammation in the nasal passages and can be used for longer periods.
  • Antibiotics: If your doctor suspects a bacterial infection is causing the catarrh, they may prescribe antibiotics.
  • Antihistamines: For catarrh caused by allergies, prescription-strength antihistamines might be necessary to control the body's reaction to allergens.

Prevention Tips

Preventing catarrh involves a combination of lifestyle and environmental adjustments. Here are some tips that might help reduce the risk or severity of catarrh:

Lifestyle Changes

  • Avoid Smoking and Smoke Exposure: Tobacco smoke can irritate the nasal passages and exacerbate mucus production.
  • Manage Stress: High stress levels can sometimes affect the immune system and make you more susceptible to infections like colds that trigger catarrh.
  • Eat a Balanced Diet: Maintaining a healthy diet supports your immune system. Consider including foods rich in vitamins C and E, which may help reduce inflammation.

Environmental Adjustments

  • Keep Your Home Clean: Regular cleaning can reduce dust and allergens that might trigger catarrh.
  • Use a Humidifier: Adding moisture to the air can help prevent the drying of nasal passages, especially in winter months.
  • Air Quality: Avoid exposure to pollutants and chemicals that can irritate the nose and throat. This may involve using air purifiers or being mindful of outdoor air quality reports.

When to See a Doctor

  • Persistent Symptoms: If your symptoms of catarrh last more than a few weeks despite home care and over-the-counter treatments, it's advisable to see a doctor.
  • Severe Symptoms: Intense discomfort from symptoms such as severe nasal congestion, sinus pain, or a significantly sore throat could indicate a more serious condition.
  • Accompanying Fever: A high fever alongside catarrh symptoms can be a sign of a bacterial infection that might require antibiotic treatment.
  • Unusual Symptoms: Symptoms like blood in the mucus, a foul-smelling nasal discharge, or wheezing when breathing should prompt an immediate visit to the doctor.
