Our noses are lined with a type of mucus, and this mucus helps to trap small particles that are inhaled in through the nasal cavities. This is beneficial to us in a number of ways, but this mucus can sometimes be the source of some irritation.

When we are ill, excess mucus can cause our nasal passages to become congested, and our noses to run. In addition, excess mucus can sometimes cause irritation by dripping down the back of the throat in a condition known as post nasal drip. There are a number of things that can cause post nasal drip, and here we take a look at some of the most common.

1. The Common Cold

Perhaps the most common of all causes of post nasal drip is the common cold. The common cold is itself a very common illness, and a majority of people would have had it at some time in their lives. It is thankfully not serious and it relatively easy to treat, but it can cause problems for people who are particularly vulnerable. One symptom of the common cold is that it will cause the nasal passages to become inflamed, and mucus production will be increased. The excess mucus needs to be exposed of somehow and this often means down the back of the throat. The flu and other illnesses can also cause the same symptom.
