Sour taste in the mouth - causes

To feel the sweet and sour taste in the mouth is quite normal. But this is only if you ate a suitable product or an unusual dish before you. It should also be noted that in such a situation, such feelings pass fairly quickly, especially if one kills one with a vegetable or milk. Although often people complain about the fact that they constantly have a sour taste in their mouth, which interferes with normal life and makes itself felt almost every day. That is why we decided to dedicate this article to why this deviation occurs in a person and how to get rid of it.

Sour taste in the mouth: causes

To say why such a phenomenon bothers certain people is rather difficult. But, after watching your body or consulting a doctor, you can still determine the true cause of its appearance, and in the future and forever get rid of it. In this regard, we offer you a detailed list of those deviations that can cause an acidic metallic taste in the mouth.

Diseases of gums and teeth

Before you visit a gastroenterologist and check for GI disease, you should pay special attention to the condition of your own teeth. After all, their darkening, the presence of caries, suppuration or pain in the gums may cause why the sour taste in your mouth regularly bothers you.

At such sensations it is impossible to forget and about metal koronkah with which the eaten food or the aerated drinks can react, thereby creating unpleasant gustatory sensations.

If the cause of this deviation is your teeth, gums, etc., then you should definitely contact the dentist. After all, only an experienced specialist will help you quickly get rid of the resulting taste.

Gastric ulcer and gastritis

The two named diseases of the gastrointestinal tract are a fairly common cause of such a phenomenon as an unpleasant taste in the mouth (most often occurs in the morning). Moreover, a stomach ulcer or inflammation of its mucous membranes (gastritis) can greatly change the color of the tongue (a yellowish-gray coating appears). But this is by no means all the symptoms by which you can determine for yourself whether you have this deviation or not. Thus, during gastritis or ulcers, a person observes the following symptoms:

  • heartburn after every meal;
  • pain in the epigastric region, manifested as an empty stomach, and after a meal;
  • belching with an unpleasant sour taste;
  • vomiting and regular nausea;
  • constipation, alternating with diarrhea.

Sour taste in the mouth, the causes of which lie in the deviations of the digestive tract, can be associated with increased release of hydrochloric acid in gastric juice. It should be noted that a fairly large number of people suffer from this pathological condition. After all, modern food contains an incredible amount of artificial supplements, which adversely affect the condition of the mucous membranes of the stomach, resulting in ulcers, gastritis and, as a result, an unpleasant aftertaste and odor from the mouth.

To get rid of this phenomenon, you should definitely visit a gastroenterologist. An experienced doctor will quickly diagnose the disease, and then appoint the necessary treatment, through which you will get rid of the disease and its unpleasant symptoms.

In medical practice, this term refers to the process of ejection of stomach contents into the esophagus. As you know, this pathology happens for various reasons. However, the result is one: a person begins to feel a sour taste in his mouth and an incredibly severe heartburn.

The most common causes of reflux and unpleasant taste in the oral cavity are the following deviations:

  • Diaphragmatic hernia. For such a disease, a significant increase in the lumen in the diaphragm is characteristic, as a result of which a part of the stomach and esophagus enter it. Constant dryness in the mouth, heartburn, sour taste, as well as shortness of breath at night, pain in the abdomen and sternum - all this indicates the presence of the presented deviation.
  • Chalasia cardia. This disease is a failure of the circular muscle located at the junction of the stomach and esophagus, which acts as a valve, preventing the consumed products from moving in the opposite direction. If you are diagnosed with chalazia, the gastric juice is easily thrown into the esophagus, which can cause a sour taste in the mouth regularly.

Diseases of the liver

Sour taste in the mouth, the causes of which are covered in liver diseases, eventually becomes stronger, and also gets a bitter shade. To diagnose this disease, you should always consult a doctor. As a rule, deviations in the work of the liver, as well as the gallbladder, are easily diagnosed by ultrasound. As a result of such a check, the following pathologies can appear in a person:

  • dyskinesia (or tonus dysfunction) of the bile ducts;
  • cholelithiasis;
  • chronic cholecystitis (or, as it is also called, inflammation of the gallbladder).

When making such diagnoses, the patient is usually given a strict diet with the exception of fatty, fried, sweet and spicy, as well as a number of medications that improve the tone of the bile ducts or destroy the formed stones.


Quite a large number of people who take medication every day, constantly complain that they are disturbed by a metallic or sour taste in their mouths. The causes of this phenomenon are often hidden in medical preparations prescribed by a doctor. So, this sensation almost always causes antimicrobial agent "Metronidazole", drugs "Trichopol", "De-nol", "Metragil", etc. If the unpleasant taste in your mouth is so strong that it interferes with your normal life, it is recommended to inform the doctor about it . If possible, the doctor must replace the medicine with a similar one that does not have such a side effect.


Often such an unpleasant feeling disturbs pregnant women, especially in later terms. According to the doctors, this phenomenon has nothing to do with the deviations in the body and has several logical explanations.

First, the multiply enlarged uterus begins to squeeze all internal organs, including the stomach. On this main digestive organ reacts in a peculiar way, enhancing the secretion of hydrochloric acid.

Secondly, in the body of the future mother, the level of the progesterone hormone increases day by day. It is he who is responsible for the relaxation of all the hollow organs, which results in the fact that part of the bile enters the stomach and esophagus.

All described processes directly affect the fact that a pregnant woman senses a strong acid taste in her mouth. Treatment of this phenomenon is reduced to the fact that the doctor recommends the future childbirth to comply with the diet and refuse from acute and harmful foods.

Other reasons

Unpleasant bitterness in the mouth is often a consequence of drinking alcoholic beverages. In addition, this phenomenon often occurs in tobacco lovers, as well as those people who can not deny themselves a dense, fat and high-calorie dinner.
