Causes and treatment of loss of taste: what to do?
About the Symptom
Loss of taste, or adhesia, is a fairly common symptom that can occur for a variety of reasons. This symptom not only causes discomfort but can also negatively impact an individual’s appetite and overall health. In some cases, loss of taste may be temporary, triggered by factors such as a cold or flu, which disrupt the functioning of the olfactory system. However, in other situations, this symptom may signal more serious diseases, such as diabetes, neurological disorders, or infections.
Understanding the causes and mechanisms leading to the loss of taste is essential for proper diagnosis and treatment. Many people note that the loss of taste sensations is also accompanied by a decrease in smell, making food less appealing and complicating the process of eating. It is important to pay attention to the duration and type of taste loss. If the symptom persists for an extended period or worsens, it is necessary to consult a doctor for examination and diagnosis. Early intervention can significantly improve quality of life and help restore normal taste sensations.
Diseases
Loss of taste, or Ageusia, can be associated with various diseases that affect the sensory organs and nervous system. This issue is often a temporary symptom, but in some cases, it may indicate the presence of more serious conditions. It is important to note that loss of taste can be accompanied by other symptoms, such as loss of smell, dry mouth, and changes in appetite. Doctors recommend paying attention to these changes and seeking medical help if concerns arise.
Among the diseases that can lead to loss of taste, the following can be highlighted:
- Viral infections (e.g., COVID-19)
- Chronic nasal and sinus diseases
- Neurological disorders (including Alzheimer’s and Parkinson’s diseases)
- Vitamin deficiency (lack of vitamins such as B12 and zinc)
- Diabetes and some endocrine disorders
- Alcohol and drug dependence
- Side effects of medications (e.g., antibiotics or chemotherapy)
- Dental and gum diseases
If you experience loss of taste, it is important to consult a qualified specialist for diagnosis and to determine the cause of this condition. Proper diagnosis will allow for timely treatment and help avoid possible complications.
Diagnosis
Loss of taste, or adhesion, can be a symptom of various diseases and a condition that requires careful diagnosis. It is important to note that this symptom can be temporary or chronic, depending on its cause. To determine the source of the problem, the patient may be asked to undergo a series of diagnostic procedures. This may include a detailed examination of the medical history and a physical examination, as well as additional tests for a more accurate definition of the pathology.
Clinics conduct various tests that help identify changes in taste receptors. The most common diagnostic methods include blood tests, neuroimaging, and tests for olfactory functions. Some diseases, such as diabetes, infections, or nervous system disorders, may be associated with loss of taste, so it is important to conduct a comprehensive assessment of the patient’s health condition.
- Blood test (general and biochemical)
- Neuroimaging (MRI or CT)
- Tests for olfactory functions
- Repetitive nerve conduction tests
- Audiometric tests (if necessary)
- Specialist examination – otolaryngologist (ENT)
Which doctor to contact
If you are experiencing the problem of loss of taste, it is important not to ignore this symptom, as it may indicate the presence of serious diseases. The first step in the treatment process should be to consult a doctor. Depending on the accompanying symptoms, the specialists you need to see may vary. Most often, patients are advised to start with a consultation with an otolaryngologist (ENT), who will perform an examination and rule out possible disorders related to the upper respiratory tract or diseases of the nasopharynx.
In some cases, loss of taste may be related not only to diseases of the oral cavity or nose, but also to neurological disorders. Therefore, in addition to visiting an ENT doctor, a consultation with a neurologist may be required. If the cause of taste loss is any internal diseases or metabolic disorders, you may be advised to see a gastroenterologist or endocrinologist. Timely consultation with specialists increases the chances of successfully restoring taste sensations and improving the quality of life.

Types of taste loss
Taste loss, also known as Ageusia or Hypogeusia, can manifest in various forms, depending on the causes of its occurrence and the individual characteristics of the patient. One of the main types is complete taste loss (Ageusia), when a person cannot distinguish any taste sensations at all. This is a serious condition that requires careful attention and thorough medical diagnosis.
The other form is called hypogeusia, when taste is diminished, and it is harder for a person to distinguish between different tastes, such as sweet, salty, sour, and bitter. In some cases, there may be a distortion of taste sensations, known as parageusia. This is a condition where tastes are perceived differently: for example, something sweet may taste bitter or salty. Awareness and correct interpretation of these types of taste loss are important for developing an effective treatment plan.
- Ageusia – complete loss of taste.
- Hypogeusia – reduced ability to taste.
- Parageusia – distortion of taste sensations.
Causes of Loss of Taste
Loss of taste is a fairly common symptom that can occur for various reasons. One of the main causes is considered to be upper respiratory infections, such as influenza or cold viruses, which can temporarily reduce smell and, consequently, the perceived sense of taste. If the sense of smell is weakened, a person may not recognize tastes as distinctly as they would in a normal state.
Other possible causes of loss of taste include injuries to the oral cavity, such as damage to the tongue or gums, as well as dental diseases that can affect taste receptors. Some treatments, including chemotherapy or certain medications, can also lead to temporary or permanent loss of taste sensations. Chronic diseases, such as diabetes or liver disease, can cause changes in taste perception in patients.
- Viral and bacterial infections
- Injuries to the oral cavity
- Dental diseases
- Use of painkillers and other medications
- Chronic diseases (diabetes, liver disease)
- Alcohol and smoking
- Deficiency of vitamins and minerals (for example, vitamin B12, zinc)
Common Related Pathologies
The loss of taste may be associated with a number of diseases and pathologies that affect the function of the olfactory and taste systems. One of the most common causes is an upper respiratory infection, such as the flu or a cold, which can cause a temporary decrease in the sensitivity of taste receptors.
Other common pathologies that may lead to a loss of taste include sinusitis, allergies, and respiratory infections. Chronic conditions such as diabetes can also adversely affect taste perception, as they disrupt metabolism and blood supply to the organs. In some cases, loss of taste may result from neurological diseases, such as Alzheimer’s disease or Parkinson’s disease.
- Upper respiratory infections
- Sinusitis
- Allergic reactions
- Diabetes
- Neurological diseases (Alzheimer’s disease, Parkinson’s disease)
- Head injuries
- Side effects of medications
Expert Opinion
Loss of taste, or anosmia, is one of the symptoms that often indicates various diseases and disorders in the body. According to specialists, this symptom can arise as a consequence of colds, upper respiratory infections, or as a result of more serious pathologies such as neurodegenerative diseases or autoimmune disorders. It is important to consider that loss of taste is not always solely related to receptor loss but can also be caused by changes in smell, which play a significant role in the perception of taste.
Many patients consult doctors with complaints of temporary loss of taste sensations following viral infections. However, in cases of chronic loss of taste, a comprehensive examination is necessary, including the study of sensory organ functions and tests for systemic diseases. Experts emphasize the importance of an individual approach to each patient and the appointment of appropriate diagnostic studies to determine the cause of this unpleasant symptom.
Timely consultation with specialists will not only help identify the cause of taste loss but also allow for the initiation of prompt treatment. If the loss of taste is a sign of a more serious condition, quick intervention can significantly affect the outcome of treatment and the quality of life of the patient.
Treatment of Taste Loss
The treatment of taste loss depends on the cause of this symptom. It is important to remember that self-diagnosis and self-treatment can lead to worsening conditions, so it is always recommended to consult professionals. The doctor will first collect the history, analyze the symptoms, and prescribe necessary research. This will help identify the underlying disease that caused the loss of flavor perception.
Among treatment methods, there may be both conservative and surgical approaches. If the loss of taste is related to infection or inflammation, antibiotics or antiviral medications may be prescribed. If the cause is an allergy, antihistamines are recommended. Also, changing eating habits and lifestyle plays a very important role, including maintaining oral hygiene and avoiding bad habits such as smoking and excessive alcohol consumption.
Thus, a comprehensive approach to treatment and early diagnosis significantly increases the chances of a complete recovery of taste sensations. By consulting specialists, patients can be assured of receiving quality help.
- Conservative treatment (medications)
- Physiotherapy
- Surgical intervention (in case of serious diseases)
- Change of lifestyle and diet
- Clinical monitoring
Complications
Loss of taste can have not only immediate consequences but also cause a number of complications that affect both the physical and psycho-emotional state of the patient. One of the most common complications is a decrease in appetite. When a person cannot distinguish flavors, they lose interest in food, which can lead to nutrient deficiencies, weight loss, and overall weakness of the body.
Furthermore, loss of taste can affect the quality of life, making social interactions difficult. Eating is often an important part of communication and cultural traditions, and deprivation of this aspect can lead to feelings of isolation and depression. Constant dissatisfaction with one’s condition can provoke emotional disorders such as anxiety and stress, which also negatively impact overall health.
- Nutrient deficiencies and vitamin deficiencies
- Psycho-emotional disorders (depression, anxiety)
- Decreased quality of life and social activity
- Development of diseases related to malnutrition
- Increased risk of accidents due to impaired sense of smell
