What is Post Nasal Drip?

Glands in your nose and throat continually produce mucus, normally one to two quarts per day. Mucus moistens and cleans the nasal lining, moistens air, traps and clears what is inhaled, and helps fight infection. Mucus is normally swallowed unconsciously, but when there is a feeling of the mucus gathering in the throat or dripping from the back of your nose, it is called post-nasal drip.

What Are the Symptoms of Post Nasal Drip?

Symptoms of post-nasal drip can include:

• Feeling of mucus drainage into the throat
• Frequent swallowing
• Throat clearing
• Raspy or gurgling speech
• Sore irritated throat
• Feeling a lump in the throat

In children, thick or foul-smelling secretions from one side of the nose can mean that something is stuck in the nose such as a bean, wadded paper, or a piece of a toy. If these symptoms are observed, seek a physician for examination.

Post-nasal drip often leads to a sore, irritated throat. Although there is usually no infection, the tonsils and other tissues in the throat may swell. This can cause discomfort or a feeling that there is a lump in the throat. Successful treatment of the post-nasal drip will usually clear up these throat symptoms.

What Are the Causes of Post Nasal Drip?

Causes of post-nasal drip can include:

• Bacterial infections
• Allergies
• Vasomotor rhinitis (overly sensitive nose)
• Medications that thicken mucus
• Gastroesophageal reflux
• Age

Thin clear secretions can be due to colds and flu, allergies, cold temperatures, bright lights, certain foods or spices, pregnancy, and other hormonal changes. Various drugs (including birth control pills and high blood pressure medications) and irregular nose cartilage can also produce increased mucus.

Thick secretions in winter often result from dryness in heated spaces. They can also come from sinus or nose infections and allergies, especially to foods such as dairy products. If thin secretions become thick and turn green or yellow, it is possible that a bacterial sinus infection is developing.

Treatment Options May Include:

Diagnosing post-nasal drip may include a detailed ear, nose, and throat exam, endoscopy (using a camera to look inside the nose and throat), or X-rays. Our doctors will recommend therapies, treatments, or lifestyle adjustments to reduce the occurrence of post-nasal drip.
