How Long Does Post-Nasal Drip Last & Ways to Get Rid of it?

What is Post-Nasal Drip?

As we breathe, the mucus glands located within nose, pharynx, trachea and bronchi continuously produces mucus secretions. This thick and wet mucus secretion keeps the nose, pharynx and airways moistened. The thick mucus secretion traps the bacteria and viruses as well as foreign bodies, and prevents them entering into body through the layers of endothelial cells lining nasal cavity and airways.

Usually, the liquid like thin nasal mucus secretion drips into throat and is often unnoticeable. The secretion eventually gets mixed with the saliva of the mouth and gets swallowed into stomach. However, when the body produces too much of thick mucus secretion within nose and throat it causes difficulties in breathing and swallowing. The nasal secretion runs in front and back of nasal cavity. The nasal discharge is known as runny nose when mucosal secretion runs through the nasal cavity outside the nose. Thin or thick nasal discharge also runs behind the nasal cavity such discharges are known as Post-Nasal Drip. Post-nasal drip causes symptoms because of collection of mucosa into the throat and irritation of throat as well as larynx. The condition is called the Post-Nasal drip.

What Causes Post-Nasal Drip?

There are various causes behind your excessive mucus production and Post-Nasal drip. The common causes are –

How Long Does Post-Nasal Drip Last?

Post-nasal drip is a very irritating condition and whenever one suffers from this condition, one wants to get rid of it as soon as possible. However, post-nasal drip usually doesn’t go away very fast. In most of the cases, Post-Nasal drip may last for several days. Unfortunately, exactly how long it will last, depends on cause of increased mucosal secretion, amount of secretion and thickness of secretion. Though it varies in each case, it can well be said that the cause of the condition has much to do with its impact and longevity. The sooner the underlying cause is treated, the sooner Post-Nasal drip will disappear. The increased secretion caused by pollen or dust allergies may last for long period of time during the pollen season. Usually, if the Post-Nasal drip is a result of flu, cold or a sinus infection, it will last roughly for about a week. The secretion of mucosa reduces once the infection is controlled with antiviral or antibiotic medications. In contrary, of course, if the condition is too serious and if treatment is delayed, it will last longer. However, in case the cause of the Post-Nasal drip is a hormonal changes or the consumption of certain medicines or even pregnancy, then it will last as long as the affecting factors persist. In case of deviated septum, swollen nasal cartilages or persistent nasal mucosal inflammation, the mucosal secretion may remain continuously high and result in prolonged post-nasal drip.

What are the Problems Associated with Post-Nasal Drip?

The intensity of symptoms and problems caused by post-nasal drip depends on amount of mucosal secretion, continuous mucosal secretion and thickness of mucosa. The excessive thick mucosa often sticks to the surface of nasal and pharyngeal (throat) wall. The thick sticky excessive mucosa often is difficult to clear by coughing or spitting. In most cases it doesn’t get cleared away from the throat. As the thick mucosal layer builds up in the throat, it creates a swallowing problem. Post-Nasal drip is not a disease itself, but a symptom of another underlying condition. It is used to describe a lumpy or thickening sensation at the back of the throat.

Congestion of the throat caused by accumulated thick mucosa is a very irritating problem that is associated with Post-Nasal drip. The presence of thick excessive mucosa at the back of the throat causes continuous feeling of need to swallow. The continuous act of swallowing or attempt to spit thick mucosa causes muscle fatigue of throat and bronchial muscles. The post nasal drip feeling often causes lack of coordination between muscles and nerves impulses. Such lack of coordination causes difficulties in swallowing or coughing and may result in laryngeal spasm. Laryngeal spasm leads to difficulties in breathing. The continuous secretion of thick and dry mucosa which adheres to wall of the throat and nasal cavity gives a feeling of constant mucosal plug almost hangs around the throat. This is sometimes quite painful.

Signs and Symptoms of Post-Nasal Drip

People, who encounter Post-Nasal Drip, often undergo a number of signs and symptoms. These include –

  • A congested throat that needs to be cleared; hence, frequent and voluntary throat clearing is common.
  • Frequent coughing is one of the symptoms of post-nasal drip.
  • Sore throat.
  • A lot of mucus in the throat.
  • A cracked or hoarse voice.
  • A runny or blocked nose is also a symptom of post-nasal drip.
  • Wheezing.

One thing that must be mentioned here is that the Post-Nasal drip can be of two types – the thin secretion of mucus and the thick secretion of mucus. Thin secretion causes symptoms like feeling mucosal dripping at the back of the nose and thick secretion causes symptoms like difficulties in swallowing, breathing and feeling of small soft object stuck at the back of the throat. The increased secretion of the thin mucus is usually caused by the cold, flu, temperature changes and even factors like pregnancy, hormonal changes as well as by eating certain spices. The thick secretion of the mucus, on the other hand, is mostly caused by prolonged allergy or infection. Often the thin mucus is seen to be transformed into thick, yellow or green mucus when persistent allergy is followed and associated with infection. This implies that the cause of this secretion is a bacterial sinus.
