If you take medicine that tastes bitter, a bitter taste may sometimes remain in your mouth. In that case, drinking water or eating candy can make the bitter taste go away right away.

However, there are times when you feel a bitter taste in your mouth even though you have not eaten anything that tastes bitter, and in such cases, you may want to suspect another condition.

A bitter taste in the mouth can occur for various reasons. Let’s take a look at what may cause it and how to improve and prevent the symptoms.

First, if you feel a sour or bitter taste in your mouth even though you have not eaten anything, you may want to suspect gastroesophageal reflux disease.

Gastroesophageal reflux disease refers to symptoms in which gastric acid or stomach contents flow back because digestive organs such as the lower esophageal sphincter do not function properly.

The main causes of a loosened lower esophageal sphincter include eating habits such as oily foods, spicy and irritating foods, late-night snacks, and overeating.

When the lower esophageal sphincter becomes loose and gastric acid or stomach contents flow back toward the esophagus, a sour or bitter taste may linger.

As such, not only can you feel a bitter taste in your mouth, but if stomach contents reflux, it can also cause symptoms such as a burning sensation in the chest, as well as hoarseness and a foreign-body sensation in the throat.

A bitter taste in the mouth can also be caused by nutritional deficiencies. If your mouth tastes bitter and food does not taste right, it may be a symptom caused by a nutritional deficiency such as zinc.

We taste through the taste buds on our tongue, and if there is a shortage of zinc, the structure and function of the taste buds may be affected, making it difficult to taste food.

A bitter taste in the mouth can also be felt due to dry mouth. If your mouth feels dry and you taste bitterness, it may be dry mouth.

If saliva is secreted below the average level, the inside of the mouth becomes dry and taste disturbances may occur, leading to a bitter taste.

In addition, if the symptoms are severe, the inside of the mouth becomes so dry that it is difficult to eat without water, and speaking may also become difficult.

Since a bitter taste in the mouth can occur for a variety of reasons, it is best to identify the cause and take appropriate measures and prevention steps.

First, because this symptom can be experienced due to gastroesophageal reflux disease, it is a good idea not to lie down immediately after eating and to make a habit of taking a light walk.

It is also good to improve your eating habits. Avoiding overeating, oily foods, coffee, and alcohol can help prevent symptoms.

Because this symptom can appear due to dry mouth, it is good to drink enough water regularly and to maintain oral care consistently.

We looked at what can cause a bitter taste in the mouth and how to manage and prevent the symptoms. Please refer to the above information and try to prevent the symptom.
