This may have happened to you once: you wake up in the morning with an acidic or bitter taste in your mouth. Why does this happen?

It is more common than you might think, and although it is nothing serious, sometimes it may indicate a reality in your body that you should keep in mind, such as a poor diet or an accumulation of bacteria. We will explain below for your peace of mind.

The simple reality is that almost all of us wake up with a strange flavor in our mouths.

Your tongue accumulates a series of bacteria stored over night that cause bad breathsomething that is uncomfortable especially when you wake up next to your significant other.

It is normal, however, doctors say that sometimes it can happen because of some kind of disease. So, it is worth knowing why.

Causes of bad morning breath

This acidic and bitter taste is usually produced by anaerobic bacteria which are behind the tongue and release small secretions of sulphur. If you don’t have this uncomfortable feeling during the day, it is because your saliva makes them disappear or destroys them.

But, during the night, saliva production drastically reduces and these elements remain on your tongue which gives you this unpleasant taste. It is something that happens to everyone.


If you suffer from sinusitis, it tends to cause a curious effect. your nasal mucus is more sensitive and therefore lets small secretions fall.

Nasal mucus is rich in proteins and is a good food for the same bacteria that we mentioned before. They multiple and appear and as a result continue producing more sulphur which causes this bad flavor in your mouth.


You may suffer from acidity in your esophagus, which may be inflamed. Digestion becomes slower and food is harder to digest. This acidity feeds the bacteria of your tongue, and thus the flavor will be especially acidic.

Liver problems

You already know that your liver has an essential function in cleansing your body of toxins, harmful and toxic elements, besides performing other special mechanisms in the metabolization of enzymes.

But it can happen suddenly, there may be some problem or you may simply need to cleanse. One of these symptoms is precisely this bitter taste in the morning.


Jaundice happens if you have a problem when metabolizing bilirubin, a disfunction that is also associated with your liver that causes changes in the red blood cells which causes a series of problems in your body.

The most evident symptoms are a yellow skin color as well as a bitter taste in your mouth that is stronger in the morning.
