Causes of bitterness in healthy people

One of the most innocent causes of bitterness in the mouth is a functional disorder of taste perception associated with biological aging of the body. The fact is that with age, the number of taste and olfactory receptors decreases, and those that remain lose half their mass.

First of all, a person loses the opportunity to feel the sweet and salty taste. But the bitter tastes he can feel for a long time. Atrophy of taste receptors begins at 40 - 50 years for women, for men, this process starts at the age of 50-60 years. Reduced secretion of saliva and increased dryness in the mouth are also a kind of persistent bitter taste.

In addition, such a symptom may appear:

  • after patient-transferred dental interventions;
  • during pregnancy, or after diagnostic / therapeutic curettage of the uterus (due to changes in hormonal levels;
  • during the patient's course of treatment with antibiotics or antihistamines;
  • in case of poisoning with toxic substances or metals;
  • in heavy smokers.

Causes of bitterness in the mouth: possible diseases

Bitterness in the mouth may accompany:

GI pathology

In particular, it is GERD, dyspepsia, gastritis, peptic ulcer, enteritis and colitis. Along with bitterness in the oral cavity, patients complain of heaviness or discomfort in the stomach, heartburn, impaired digestive function.

These unpleasant symptoms can join nausea, vomiting, diarrhea, bloating.

Diseases of the liver, gallbladder and its ducts

The liver is one of the most important organs of digestion. It is responsible for the production of bile and its transportation to the gallbladder and intestines. If one of these processes is disturbed, the bile begins to stagnate, after which it is thrown into the esophagus. From here there is a bitter taste in the mouth.

But this is not the only symptom. Pathological lesion of the liver is also indicated by heaviness in the right hypochondrium, increasing discomfort, yellowing of the skin and eye proteins, and the formation of a yellowish deposit on the tongue.

Oral cavity pathologies

If bitterness has appeared on the background of pain in the tooth, gum or dental-toothed tissue, then it is one of the signs of dental pathologies. Sometimes such an unpleasant taste occurs after certain manipulations, such as pulling out a tooth.

Poor dental implant or crown, the use of drugs for anesthesia or disinfection of the oral cavity is also often the cause of bitterness. Gingivitis, periodontitis, a violation of the innervation of the language can also be attributed to the causes of this unpleasant phenomenon. Diseases of the oral cavity must be treated, until they lead to more serious problems.

Helminthiasis and worm infestations

Parasites that live in the intestines, gradually provoke destructive processes in the tissues of its mucosa.

For example, Giardia tend to attach to the intestinal walls, violating their integrity. As a result, they are irritated and, as a result, indigestion. As a result of violations of glycocalyx and obstacles to the full absorption of useful substances, there is a failure in fat, protein, carbohydrate metabolism, and general metabolism.

The patient may develop beriberi, allergies, appear dry, obsessive cough. Parasitic invasions require compulsory treatment - drug or folk. In the second case, it is recommended to use a decoction of tansy or wormwood. They can be taken orally or used for cleansing enemas.

Hormonal imbalance

First of all, an imbalance of thyroid hormones (T3, T4) and adrenal glands (adrenaline, norepinephrine) can provoke bitterness in the mouth.

The latter cause a spasm of the biliary tract, so the bile is thrown into the esophagus. No events will give results if you do not adjust the hormones.


This endocrine disease is characterized by metabolic disorders in the body of varying severity. The longer the disease progresses, the more severe the disorder. In addition to bitterness in the mouth, diabetes mellitus is also accompanied by short-term problems with vision, excessive sweating in the whole body, a feeling of heat or, on the contrary, severe cold in the feet.

All these symptoms are particularly acute in type 2 endocrine pathology, and are accompanied by a sharp increase in blood sugar levels.

Drug reaction

Many diseases are treated with antibacterial drugs. Many of them tend to have an impact on the liver, passing through the process of metabolism. If you take antimicrobial medicines for a long time or uncontrollably, bitterness in your mouth is unlikely to be avoided.

In addition, the components of such funds gradually neutralize the healthy intestinal microflora. This also affects the state of health, and not only can there be a bitter taste in the mouth, but also a general taste perception for a while.

In order to avoid intestinal dysbiosis, it is necessary to take probiotics - Laktimak, Acidolac, Linex, Hilak Forte, etc. This disorder can also cause a bitter taste in the mouth, and besides it, a lot of other unpleasant symptoms.

Bitter mouth during pregnancy

Most often, bitterness in the mouth occurs in pregnant women in the last months of the gestational period. It is connected with the fact that the fetus, having increased in size, presses against the walls of the intestine, and shifts it upwards. In parallel with this, under the influence of elevated progesterone, the valve located between the stomach and the esophagus relaxes.

But bitterness in the mouth is not the only unpleasant symptom from which pregnant women suffer. Due to the slowing of intestinal motility, future mothers often suffer from constipation or, on the contrary, diarrhea, flatulence, and abdominal pain.

During pregnancy, a bitter taste in the mouth can persist until the moment of delivery. If it is not associated with pathological disorders of the gastrointestinal tract or somatic diseases, then it is not recommended to fight it with medications. But you can try to reduce the intensity of its manifestation with the help of fractional power. It will be a good way to get rid of heartburn, which also torments expectant mothers.

If the burning sensation in the esophagus does not pass, it is necessary to divide 1 portion of food into 2 doses. It is recommended to eat at the same time 5-6 times with intervals of 1.5-2 hours. Eat any drinks best in between meals.

Some women use peppermint to combat toxicity. Of course, it helps to get rid of heartburn, because it has the property to lower gastric acidity. But this plant, if it is used excessively in any form, can cause a stronger feeling of bitterness in the mouth.

Bitterness in the mouth after eating: reasons

The feeling of bitterness in the mouth may appear after eating fatty foods, as well as after overeating. This is a fairly common symptom of pathologies of the liver, gallbladder and its ducts.

In addition, bitterness in the mouth often appears in pregnant women. But such a taste is not a symptom of pathology, but occurs against the background of hormonal changes. Under the influence of progesterone, a weakening of the valve separates the gastric contents from the esophagus. The consequence of this is the presence of - permanent or periodic - bitter taste in the mouth. In the late gestational period, the enlarged uterus begins to put pressure on the gallbladder and stomach.

Patients who take antibiotics or other "heavy" drugs, also often have a bitter taste in the mouth. It is often caused by stressful situations.

Morning bitterness in the morning: a sign of what disease?

The feeling of bitterness in the mouth in the morning may indicate a rejection of bile into the esophagus, which is often observed in GERD. Also, a similar symptom may indicate a malfunction of the liver.

It is extremely difficult to identify hepatic pathology at the initial stage of its development, since the pain in the right hypochondrium appears even when the disease has passed to the late stage of development. But at home, nevertheless, you can spend a little test. To do this, you need to eat 100 - 200 g of beets - fresh or as part of a vegetable salad. After that you should drink a glass of pure non-carbonated water or green tea.

During the next urination should pay attention to the color of urine. If the urine has acquired a red tint, it means that there is a hepatic pathology.

Bitterness in the mouth and pain in the right side: what is the reason?

Pain in the right hypochondrium often indicates the presence of cholecystitis. If it is combined with a bitter taste in the mouth, the exacerbation of hepatic pathologies may be the cause.

In this case, mechanical jaundice does not always appear. Pain is present only in the later stages of the development of the disease, when the liver grows in size. In case of pathological lesions of the liver, the appearance of heaviness in the right side after physical exertion may also be observed.

Which doctor to contact for diagnosis and treatment?

If the bitterness in the mouth becomes obsessive, you need to turn to the therapist. After a detailed survey and examination, the doctor will refer the patient to a specialist:
