Changing taste preferences: reasons and impact on health
About the Symptom
Changes in taste preferences are a symptom that may indicate various medical conditions and disorders. People may experience unexpected changes in what they prefer to eat or drink, which can be related to both physical and psychological factors. For example, some diseases, such as diabetes or thyroid disorders, can affect taste perception and alter preferences. In other cases, changes in taste preferences may result from treatment, such as antibiotic therapy, which can temporarily impact smell and taste.
Furthermore, changes in taste preferences can also be linked to stress, depression, or other mental disorders. Studies show that a person’s emotional state can significantly influence their desire to consume certain foods. For instance, during times of stress, an individual may reach for sweets or fatty foods that provide a temporary sense of comfort. Therefore, it is important to consider not only physical but also emotional aspects when it comes to changes in taste preferences, as this can aid in diagnosis and the appropriate approach to treatment. If you notice sudden changes in your preferences, it is recommended to consult a specialist to determine possible causes and receive appropriate assistance.
Diseases
Changes in taste preferences can be a symptom of various diseases and conditions that affect the functioning of the sensory organs, including taste. For many patients, this may manifest as a desire to consume unusual foods or, on the contrary, an aversion to familiar dishes. Such changes can significantly impact the quality of life and nutrition, which, in turn, can lead to a deficiency of essential nutrients.
There are several diseases that can cause changes in taste preferences. It is important to be attentive to the signs and to consult a doctor in a timely manner to determine possible diseases and their treatment.

Types of Changes in Taste Preferences
Changes in taste preferences can manifest in various forms, which can vary significantly from person to person. The main types of such changes are hyperdeveloped taste perception (hypergeusia), characterized by increased sensitivity to certain tastes, and their suppression, such as ageusia or hypogeusia, where a person loses the ability to sense or notice certain tastes. These changes can occur as a result of various factors, including medication, dietary changes, or age-related changes.
Moreover, changes in taste preferences may be related to a person’s psycho-emotional state. Some patients report experiencing a craving for unusual tastes during periods of stress or emotional excitement. For example, during such moments, there may be a desire to eat certain foods that previously did not provoke interest, or, conversely, to reject previously loved dishes. These changes can become temporary or permanent, depending on the reasons that caused them.
- Hypergeusia (increased sensitivity to tastes)
- Ageusia (loss of the ability to distinguish tastes)
- Hypogeusia (reduced ability to perceive tastes)
- Dysgeusia (distorted perception of tastes)
- Psychogenic changes in taste preferences
Reasons for Changes in Taste Preferences
Changes in taste preferences can be caused by a variety of factors, both physiological and psychological. One of the most common reasons is changes in health status. Conditions such as a cold or sinusitis can temporarily affect taste perception as they go hand in hand with changes in smell. Other diseases, such as diabetes or thyroid disorders, can also impact taste receptors and lead to changes in food preferences.
Psychological factors also play an important role in changing taste preferences. This may be related to stress, depression, or other emotional states. For example, in some cases, food becomes a means of comfort, leading to a change in usual taste preferences, pushing people towards sweeter or fattier foods. Finally, age-related changes can also influence taste preferences, as with age, the intensity of taste perception may decrease, causing a person to seek out more vibrant and pronounced flavors.
- Upper respiratory tract diseases
- Depression and stress
- Chronic digestive organ diseases
- Vitamin and mineral deficiencies
- Hormonal changes
Common Related Pathologies
Changes in taste preferences can be associated with various diseases and pathologies that affect the functions of smell and taste. These changes may indicate the presence of both physical and mental disorders. For example, oral diseases such as stomatitis or gingivitis can significantly alter taste perception, causing discomfort while eating. Neurological disorders, such as Alzheimer’s or Parkinson’s disease, also play an important role, as they can impact the mechanisms of taste perception.
Mental disorders such as depression or anorexia can also lead to changes in taste preferences. Individuals suffering from these conditions often experience a loss of interest in food, or conversely, a craving for unusual or even unappetizing products. Given the impact of these diseases, it is important to pay close attention to changes in one’s taste preferences and consult a medical professional in case of noticeable deviations.
- Oral diseases (stomatitis, gingivitis)
- Neurological disorders (Alzheimer’s disease, Parkinson’s disease)
- Endocrine disorders (diabetes, hypothyroidism)
- Mental disorders (depression, anorexia)
- Allergic reactions (reactions to certain foods)
Expert Opinion
Changes in taste preferences are a complex symptom that can indicate various physiological and psychological processes in the human body. A dietitian and nutritionist emphasizes that sometimes such changes can be caused by temporary factors, such as stress, hormonal fluctuations, or changes in diet. However, if changes in taste persist for a long time, it may indicate the presence of serious diseases that require the attention of specialists.
Experts also stress the importance of an individual approach to each patient. Taste preferences can change not only due to physiological reasons but also because of cultural factors and environmental characteristics. Studying these changes can help establish a more accurate diagnosis and identify hidden health problems. Therefore, in the case of prolonged changes in taste habits, it is recommended to consult a doctor for further examination and guidance on dietary adjustments.
Treatment of Changes in Taste Preferences
The treatment of changes in taste preferences depends on the cause that triggered this symptom. In most cases, conservative methods aimed at eliminating the underlying problem are prescribed. If the changes in taste are related to a deficiency of vitamins or minerals, the treatment includes dietary adjustments and the intake of necessary supplements. It is important to note that changes in taste preferences can often be temporary and may occur in response to specific changes in the body or during stress.
When changes in taste are caused by more serious pathologies, such as infectious diseases or neurological disorders, the treatment will involve more comprehensive approaches. This may include the prescription of antibiotics, antiviral agents, or neuroprotectors. In some cases, therapy from different specialists may be required, allowing for the development of an optimal treatment strategy.
- Dietary correction
- Intake of vitamin and mineral complexes

Complications
Changes in taste preferences can have serious consequences for health and overall well-being. One of the main complications is the risk of undernutrition or overeating, which in turn can lead to the development of various diseases, such as diabetes or obesity. Uncontrolled changes in diet can not only affect physical health but also negatively impact emotional well-being, which may lead to eating behavior disorders.
Another serious complication is the possibility of diseases related to metabolic or substance exchange disorders. For example, consuming unfamiliar or inappropriate foods can cause allergic reactions or gastrointestinal disturbances. Therefore, it is important to monitor one’s taste preferences and listen to the body to avoid negative health consequences.
