Major Causes Of Post-Nasal Drip

Post-nasal drip is a symptom of many medical conditions. Worse than a runny nose, post-nasal drip involves the accumulation of mucus in the back of the throat. Normally, mucus is swallowed unconsciously, but patients with post-nasal drip may have the unpleasant sensation of mucus dripping down the back of their throat. Patients who have post-nasal drip may frequently clear their throats and may have a cough that worsens at night. Patients may also experience a hoarse voice, stuffy nose, bad breath, and sore throat. To determine the cause of post-nasal drip, primary care providers and ear, nose, and throat specialists will take the patient's health history and perform a physical examination. The majority of cases of post-nasal drip are not serious and resolve in a short time. If the physician suspects the post-nasal drip may be due to a bacterial infection, antibiotics may be prescribed. Patients who have frequent episodes of post-nasal drip may need more advanced treatments.

Let's explore some of the most common causes of post-nasal drip in more detail.

Viral infections such as the common cold and the flu frequently lead to the development of post-nasal drip. Unlike bacterial infections, infections caused by viruses cannot be resolved with antibiotics. Common cold and flu symptoms include a headache, fever, chills, muscle aches, cough, runny nose, fatigue, and sneezing. While cold symptoms usually resolve within ten days, the fatigue caused by flu can last for several weeks. Patients are encouraged to drink plenty of fluids to help break up the mucus associated with viral infections, and certain over the counter medications can help reduce mucus production. Dairy products should be avoided when patients have a viral infection, as consuming dairy increases mucus buildup.
