Pain symptoms, high temperature, chills - all these are signals that the human body is trying to say that it is being exposed to some negative impact and the progression of pathology. Bitterness in the mouth in the morning can also be attributed to such factors. After all, it does not appear just like that - there must be a reason that generates it.
Causes of bitterness in the mouth in the morning
It is quite problematic to make a definite diagnosis, having only a bitter taste in the mouth in the symptoms, because the causes of bitterness in the mouth in the morning are very diverse and cover not only the physical plane of pathology, but also the emotional one. Therefore, we will try to dwell on this issue in as much detail as possible.
- One of the main reasons for the unpleasant sensation in the mouth that occurs in the morning is a malfunction of the gallbladder, the processes of production and excretion of bile, pathological changes that provoke the reflux of bile back into the esophagus.
- Unpleasant morning symptoms may also be the result of overeating the night before.
- Bitterness in the mouth in the morning may be the body's response to certain foods. The most irritating to the intestinal mucosa are spicy, fried, bitter, salty and fatty foods. Some types of nuts also have the ability to cause bitterness.
- Taking antibiotics can also provoke similar symptoms, as they affect pathogenic flora and destroy the “good” bacteria necessary for normal bowel function. This is where intestinal dysbacteriosis comes from, which can cause bitterness.
- The cause of bitterness in the mouth in the morning can be pathological changes of a dental nature: diseases of the teeth and gums, improperly made prosthesis or material of the crown and filling. Together with bitterness, with this pathology, you can often feel an unpleasant odor coming from the oral cavity.
- They provoke discomfort and multiple pathologies of the gastrointestinal tract.
- Diseases affecting the structure or functional function of the liver.

Symptoms of bitterness in the mouth in the morning
It is unpleasant to wake up with a feeling in your mouth as if you have been sucking on a bitter pill for a long time and forgot to wash it down with water. The sensation is not pleasant, causing considerable physical discomfort. Many people know the symptoms of bitterness in the mouth in the morning, especially often it begins to visit a person with age, when after many years he has acquired a wide variety of various chronic diseases. Bitterness in the mouth in the morning is an independent symptom, which is an indicator of one or more diseases progressing in the patient's body. Therefore, when such discomfort appears, it is necessary to listen more carefully to your body, analyze previous actions, determine the accompanying symptoms. It will not be superfluous to consult a specialist who, having analyzed the clinical picture and the results of the studies, is able to make the correct diagnosis and prescribe adequate treatment.
Bitterness in the mouth in the morning - as a symptom of disease
Did a stormy birthday or New Year's Eve result in morning bitterness in the mouth? If such discomfort is observed quite rarely and is directly related to overeating the day before, it is not so bad, although unpleasant. But bitterness in the mouth in the morning can manifest itself as a symptom of a disease, and this can already be quite serious. Let's try to figure out what diseases can cause such symptoms and, mainly, what accompanying signs are usually observed with a particular disease.
- Quite often, the presence of a bitter taste in the mouth indicates dental problems. This could be:
- Abscess on a tooth.
- Gingivitis is an inflammatory disease of the mucous membrane of the gums, most often found in children.
- Increased sensitivity of the human body to the components of the filling material. Usually, the response occurs some time after the tooth has been filled. In such a situation, you need to contact the dentist who performed the procedure and inform him. Perhaps it will be enough to change the filling material, and the problem will be solved.
- Gastroesophageal reflux disease is one of the most common chronic pathologies of the digestive system, an acid-dependent disease caused by deterioration of the motor activity of the upper gastrointestinal tract. It is caused by spontaneous, regularly repeated reflux of gastric and/or duodenal contents into the esophagus. In this case, you simply cannot do without a diet. Overeating, spicy, fried and fatty foods - such foods effectively provoke acid reflux. The cause of bitterness can also be improper organization of your diet throughout the day: long intervals between meals, but abundant feasts. Accompanying factors can be heartburn, increased flatulence and unpleasant breath.
- A change in a person's hormonal background, which occurred for whatever reason. A deviation from the estrogen norm gives a particularly obvious bitterness. This is mainly the reason for the appearance of a bitter taste in the mouth of a pregnant woman during the bearing of her baby.
- Bitterness in the mouth in the morning can signal that the body is poisoned by metals. Most often, these can be metals such as lead, liquid mercury, copper. In this situation, you should not waste time, you must immediately seek emergency medical help from a doctor. Some metals are quite toxic and delay can cost the victim his life.
- Quite often, the cause of unpleasant symptoms are disorders that affect the liver. After all, this organ takes an active part in the processes of breaking down nutritious products.
- The gallbladder can be a source of unpleasant sensations. Malfunctions - when bile does not enter the digestive tract regularly, which does not allow the incoming food to be processed efficiently. The same disorder provokes disturbances in the functioning of intestinal motility.
- Stagnation of bile. It is bile that allows fats to emulsify.
- Cholecystitis is an inflammatory process occurring in the mucous membrane.
- Dyskinesia of the biliary tract.
- Gallstone disease.
- Tumor or infection of an organ.
- Pancreatitis is an inflammation of the pancreas.
- And others.
- Malfunction of taste buds (dysgeusia).
- Disease of the endocrine system, in particular diabetes mellitus.
- Bitterness in the mouth in the morning as a symptom of illness may indicate a malfunction of the kidneys.
- Basic failure to observe oral hygiene rules, rotting food stuck in the teeth. All this can cause discomfort.
- A malfunction of intestinal peristalsis can also provoke such symptoms. In this situation, it is necessary to adjust your diet, eliminating “heavy foods” from it: smoked foods, spicy and salty dishes, foods containing a lot of fat. It would also be correct to change your diet: you need to stop eating at least two hours before going to bed. At night, the whole body needs rest, during this period all physiological processes are inhibited. Therefore, eating late is a risk of incomplete digestion of food and receiving a response from your body to this. A positive aspect of giving up late meals will be the restructuring of the body prone to excess weight.
- There are cases when the cause of bitterness is a decrease in the rate of passage of a portion of food through the digestive tract, while the liver and gall bladder with their system function within normal limits. This is explained by the fact that in addition to food and digestive juice, bile is also present in the intestines.
- There are products that have pronounced choleretic properties. If you consume them in sufficient quantities, you can feel the bitterness in your mouth. Any kind of nuts are one of these products. The body's response can appear several hours after eating nuts. In this situation, it is better to reduce the use of your favorite delicacy, or even give it up altogether, at least for a while.
- Bitterness in the mouth in the morning can also be caused by pathological changes in the ENT organs.

Diagnosis of bitterness in the mouth in the morning
If a person feels an unpleasant bitter taste in the mouth in the morning, and such symptoms begin to bother quite often, and are not a one-time result of yesterday's banquet, then you should not ignore the signals of your body and, without putting it off, you need to go to a specialized clinic for an appointment with a specialist. Only a qualified doctor can correctly diagnose, identify the source of irritation, and prescribe the necessary therapy. If the discomfort is associated with pathology of the teeth and gums, then the diagnosis of bitterness in the mouth in the morning comes down to an examination by a dentist. If necessary, he can prescribe an X-ray examination.
In case of pathological changes of a different nature, other methods and their combinations can be used. The following examination methods are most often in demand:
- Examination of the skin allows to confirm or remove hepatitis from the list of suspected diseases. If suspicion still remains, liver tests are taken, which make it possible to assess the state of the enzymatic system: the amount of some enzymes, cholesterol, bilirubin and other components in the body.
- Clinical examination of the patient's feces and urine.
- Blood sugar test and clinical analysis.
- Palpation of the liver area to control its size and density, checking the condition of the gallbladder.
- Almost no examination today can be done without ultrasound (ultrasound examination).
- Retrograde cholangiopancreatography (ERCP) is one of the most modern and effective methods of medical diagnostics, which includes a combination of endoscopy with simultaneous X-ray examination of the duodenum. A contrast agent is supplied to the object being examined through a special endoscope channel, after which a good quality X-ray image of the entire biliary system is obtained.
- Endoscopic retrograde cholangiopancreatography (ERCP) is a highly informative, although unsafe, method of direct contrasting of the biliary and pancreatic systems (X-ray examination of the pancreatic ducts and bile ducts after the introduction of a contrast agent through the ampulla of Vater).
- If there is a suspicion that bitterness in the mouth in the morning is associated with the consumption of certain foods, special tests are carried out to differentiate “dangerous” foods and adjust the daily diet, removing “provocateurs” from it.
Only after conducting a full range of examinations can a doctor adequately assess how difficult the situation is and determine how to get out of it.

Treatment for bitterness in the mouth in the morning
Treatment of bitterness in the mouth in the morning largely depends on the cause that provokes the development of the uncomfortable pathology that bothers a person during the period of awakening.
If gastroesophageal reflux disease is diagnosed, the doctor may prescribe domperidone, which is taken orally 15 minutes before the expected meal. The dosage of the drug is 10 mg, taken three to four times a day. If the baby weighs between 20 and 30 kilograms, the dosage is reduced to half a tablet twice a day; if the body weight is above the upper limit, one whole tablet is administered twice a day.
Small patients may be prescribed the drug in a 1% solution, which is administered orally at a rate of one drop per kilogram of the baby's weight. The medicine is taken three to four times a day.
If necessary, the dosage of the drug can be doubled. The maximum daily dose is 80 mg. If the patient suffers from renal failure, the quantitative component of the drug should be reduced, and the number of injections should be reduced.
Domperidone is contraindicated for use in case of gastrointestinal bleeding, ulcerative manifestations of the digestive system, intestinal obstruction, individual intolerance to the components of the drug, in case of pregnancy and breastfeeding. The drug is strictly prohibited for administration to infants whose weight has not reached 20 kilograms.
In case of diagnosis of diseases such as gastritis, colitis and pancreatitis, more narrowly targeted drugs are prescribed, such as omeprazole, furazolidone, pancreatin, etc.
Furazolidone is taken after meals with a sufficient amount of liquid. The daily dosage for adults is 0.4 g, divided into four doses. The largest single dose of the drug is 0.2 g, the daily dosage should not exceed 0.8 g.
Contraindications to furazolidone include the following manifestations:
- Increased individual intolerance to one or more components of the drug.

- If the patient's professional activity is associated with working on moving, structurally dangerous mechanisms, as well as driving vehicles.
In such a situation, hepatoprotectors are also prescribed, which are intended to participate in the therapeutic and restorative liver therapy. They allow normalizing the work of the bile duct system, stabilizing the situation. You can use ursodeoxycholic or lipoic acid, methyluracil, ademetionine, bemitil.
The ademetionine solution is prepared immediately before use. The method of administration of the drug is determined by the doctor: intravenously or intramuscularly. The dosage for intensive therapy is from 5 to 10 mg per day, which corresponds to 0.4 - 0.8 g of the active substance. In the case of maintenance therapy, the doctor mainly prescribes the drug in the form of tablets, which are administered to the patient orally between meals in a dosage of two to four units per day.
It is not recommended to prescribe the drug to patients with a history of pathological changes in the liver of various origins, withdrawal and depressive syndromes.
If gallstone disease is diagnosed, then in most cases the patient is prescribed surgical intervention, drug treatment, in any case it would not be a bad idea to reconsider the diet.
In case of problems with the bile-excreting system (except for kidney stones of significant size), the doctor prescribes herbal choleretic infusions (these can be corn silk), as well as diuretic drugs such as allochol, holosas, holagol, flamin, carsil, holenzym, holagogum. The drugs are designed to normalize the functioning of the liver, gallbladder and intestines.
Allochol is prescribed after meals in doses of one to two tablets taken three to four times a day. The duration of such therapy is three to four weeks. The next stage of treatment is taking one tablet two to three times a day for one to two months. If necessary, the course of treatment is repeated at intervals of three months.
The drug is not prescribed in cases of severe hepatitis and jaundice, ulcerative-erosive pathology of the gastrointestinal tract and duodenum, as well as liver failure.
Holosas is a bile medicine that is prescribed by a doctor and taken orally one teaspoon by adult patients and a quarter or half a teaspoon by small patients. At the same time, contraindications and side effects when taking the drug have not been identified to date.
Motilium has also proven itself to be excellent, effectively working to normalize intestinal peristalsis.
The drug motilium is most effective when administered 15-30 minutes before the expected meal. In case of medical necessity, it can be administered immediately before going to bed. For adult patients, the dose of the drug varies from 10 mg (one tablet) to 20 mg (two tablets), administered three to four times a day. If the therapy is ineffective, the quantitative administration of the drug can be doubled, but the daily dosage should not exceed 80 mg (2.4 mg per kilogram of the patient's weight).
This medicine is prescribed only to adult patients and children whose weight has exceeded 35 kilograms. It is not recommended to take motilium in case of hypersensitivity to the components of the drug, with internal bleeding affecting the gastrointestinal tract, with hyperprolactinemia, perforation of the intestinal and stomach walls, prolactinoma.
If bitterness in the mouth in the morning is a consequence of nervous tension or a stressful situation, then it would not hurt to take, for some time, herbal teas with soothing herbs: mint, lemon balm, motherwort.
