A post nasal drip is where the normal process of mucus production, which is essential to help fight infection, becomes excessive and thicker and causes a sensation that makes you want to cough or clear your throat frequently.
Causes of a post nasal drip include cold and flu viruses, allergies, sinus infections, polyps, deviated nasal septum, medications, some foods and changes to climate and air pollution. Post nasal drip can affect anyone but it is more frequent with increasing age due to swallowing issues or gastroesophageal reflux disease.
Symptoms include wanting to continually clear your throat , sore throat and a chronic cough which is often worse at night- hence often causing disruption to sleep.
Treatment varies according to the cause of the post nasal drip and can include antihistamines and decongestants which thin and dry up the excessive mucus and reduction of response to allergens, saline drops to clear the nasal passages, antibiotics to fight infection and even surgery if there are polyps or deviation of the nasal septum.
As sleep can be affected it may be a good idea to sleep propped up by pillow. It is a good idea to ensure that your pillows and mattress are covered with dust mite proof covers as dust mites are often a cause of allergic reactions which can make you produce more mucus due to inflammatory reaction by the body.
Good bedroom hygiene and regular dusting and hoovering can also reduce reaction to dust and mites.
Taking decongestants as previously mentioned can help as well as steam inhalations and the use of vaporisers with oils such as eucalyptus, lavender, clove, lemon and peppermint. These oils can aid with relaxation as well as having antibacterial and decongestant properties.
Diet can also affect mucus production – too much dairy , starchy and sugary foods all increase mucus production so it may be wise to reduce the intake of these generally. It is also very important to keep well hydrated particularly with water.
As you say that this appears to be an on going issue every winter period it may be good to ask for your GP to refer you for ENT assessment to exclude physical factors which may be making this worse for you. It would also be important to have infection excluded if the mucus becomes offensive in smell and contains blood or you develop a fever.
