Sensitivity to smells: causes, symptoms, and treatment
About the symptom
Sensitivity to smells, also known as hyperosmia, is a condition in which a person experiences an excessive perception of various aromas. This symptom can manifest in a wide range of situations: from a strong reaction to familiar smells in everyday life to a decline in overall well-being when in aromatic environments. For people suffering from hyperosmia, even ordinary smells, such as perfume, food, or household chemicals, can be perceived as unpleasant or irritating, which can significantly impair quality of life and cause emotional discomfort.
Hyperosmia can be caused by various factors, including hormonal changes, the use of certain medications, as well as nervous or psychological disorders. For example, many women note an increased sensitivity to smells during pregnancy, which is related to changes in hormonal levels. This symptom can also occur with migraines or after having infectious diseases. It is important to understand that hyperosmia is not an independent disease, but rather a symptom indicating possible disturbances in the body, so its manifestations should be taken seriously and, if necessary, medical help should be sought.
Diseases
Sensitivity to smells, or hyperosmia, can be a symptom of a range of diseases and conditions. This increased sensitivity to aromas can arise from various disruptions in the body, including neurological disorders, allergic reactions, and even some infections. Patients often report that ordinary smells become excessively intense and even unpleasant, which can significantly affect their quality of life.
Some of the diseases associated with increased sensitivity to smells include:
- Migraine
- Diabetes
- Alzheimer’s disease
- Candidiasis
- Various allergic reactions
- Parkinsonism
- Neuritis
It is important to remember that the presence of hyperosmia is not a diagnosis but merely a symptom that requires thorough medical investigation to identify the underlying disease and determine appropriate treatment.
Diagnosis
The diagnosis of sensitivity to smells is an important aspect of medical examination, as it can be related to various diseases and disorders. The doctor, observing the patient’s symptoms, may use several diagnostic methods to determine the causes of increased sensitivity to smells. This may include both the medical history and special tests aimed at assessing olfactory function and excluding other pathologies.
In the context of diagnosing sensitivity to smells, a variety of studies may be conducted, including olfactory tests, neuroimaging, and other laboratory analyses. Identifying the causes that led to this condition can help develop an appropriate treatment plan and improve the patient’s quality of life. It is important to note that diagnosis should be conducted by qualified specialists, as incorrect interpretation of symptoms may lead to inappropriate treatment.
List of diagnostic services:
- Medical history and physical examination
- Olfactory tests (including smell thresholds)
- Neuroimaging (MRI or CT)
- Blood laboratory tests to identify systemic diseases
- Allergy tests
- Nasal endoscopy
- Tests to determine serotonin and dopamine levels
Which doctor to consult
Sensitivity to smells, also known as hyperosmia, can be a manifestation of various diseases or conditions, so it is important to consult a specialist for accurate diagnosis and treatment. Usually, the first step in this direction is a consultation with a therapist who will conduct an initial assessment of the condition and, if necessary, refer to a more specialized doctor. It is important not to ignore this symptom, as it may indicate more serious health issues.
After the initial assessment, a consultation with an otolaryngologist may be needed, who specializes in diseases of the ear, throat, and nose. This specialist will help determine whether hyperosmia is related to issues in the upper respiratory tract, as well as investigate the influence of allergies or infections. In some cases, a consultation with a neurologist may also be required to rule out diseases of the central nervous system that may lead to changes in smell perception. Thus, the approach to diagnosis should be comprehensive and include specialists from various fields of medicine.

Types of Sensitivity to Smells
Sensitivity to smells can manifest in different forms, which directly depends on the characteristics of each person’s body. The main types are hyperosmia, anosmia, and dysosmia. Hyperosmia is characterized by increased sensitivity to smells. This can be caused by various factors, including hormonal changes, stress, or even diseases such as migraines. People suffering from hyperosmia may experience severe anxiety and discomfort in the presence of familiar smells around them.
Anosmia is the complete loss of the ability to distinguish smells, which can be caused by upper respiratory infections, head injuries, or neurodegenerative diseases. In turn, dysosmia implies a distortion of smell perception, where familiar aromas start to evoke unpleasant associations or are perceived in a distorted manner. All these conditions can significantly impact the patient’s quality of life, requiring special attention to diagnosis and treatment.
List of types of sensitivity to smells:
- Hyperosmia
- Anosmia
- Dysosmia
Causes of Sensitivity to Smells
Sensitivity to smells, or hyperosmia, can arise from various reasons and range from physiological factors to diseases. One of the most common reasons is hormonal changes, which are often observed during pregnancy. Women may notice that smells they once liked become unbearable, or conversely – those they disliked begin to evoke pleasant associations. Additionally, certain medications, such as antidepressants or antihistamines, may also cause changes in smell perception.
Frequently, heightened sensitivity to smells is a sign of neurological conditions, such as migraines or disorders related to the olfactory lobe of the brain. In some cases, hyperosmia may be linked to allergic reactions that produce increased mucus secretion, which affects the functioning of olfactory receptors. It is also worth considering that our emotions and mental state can significantly influence the perception of smells. Stress or anxiety can lead to an intensified reaction to smells, making them sharper and more unpleasant.
- Hormonal changes (e.g., pregnancy).
- Medications (antidepressants, allergy medications).
- Neurological disorders (migraine, olfactory function disorders).
- Allergic reactions.
- Emotional states (stress, anxiety).
Common Related Pathologies
Sensitivity to smells, also known as hyperosmia, can be a symptom of various diseases and health conditions. It is often accompanied by other changes in perception, such as a change in taste sensations or the emergence of unpleasant odors, which can cause significant discomfort. If sensitivity to smells is an isolated symptom, it may indicate temporary changes in the body, but if it lasts for a long time, it may signal more serious disorders.
Among the common pathologies associated with increased sensitivity to smells, we can highlight migraine, allergic reactions, respiratory infections, as well as neurological disorders such as Alzheimer’s or Parkinson’s disease. Additionally, paradoxical sensitivity to smells can also be observed in people who are under stress or suffering from depression, which also requires attention from specialists.

Expert Opinion
Sensitivity to odors, also known as hyperosmia, is a condition in which a person perceives environmental scents excessively sharply. This can be caused by both physiological and psychological factors. In clinical practice, it is observed that men and women may react differently to smells; women often experience heightened sensitivity during the menstrual cycle or pregnancy. Experts believe that this condition may result from changes in hormonal levels, diseases, or even stress.
It is important to note that the sensation of overly strong odors can significantly impact quality of life. People with hyperosmia often face issues related to sharp smells that can trigger headaches, nausea, or even panic attacks. However, in some cases, heightened sensitivity may serve as an adaptive mechanism, allowing avoidance of harmful substances or toxins. It is essential to consult specialists to determine the underlying causes and potential treatment for this pathology.
Treatment of Sensitivity to Smells
Sensitivity to smells, or hyperosmia, can significantly affect a person’s quality of life, causing discomfort and even stress in daily activities. Treatment for this condition may vary depending on its cause and severity. In most cases, the primary task in addressing the issue of sensitivity to smells is to identify and eliminate the underlying cause of the condition. For example, if symptoms are triggered by allergic reactions, it is important to conduct a complete allergy analysis and, if necessary, use antihistamines.
Additional treatment methods may include therapy to relieve stress, as increased sensitivity to smells is sometimes associated with psycho-emotional disorders. A comprehensive approach, consisting of medication and psychotherapeutic support, can have a positive impact on the patient’s health. It is also advisable to consult an otolaryngologist, who can assess the condition of the olfactory system and suggest the most appropriate treatment methods for the specific case.
- Examination by an allergist
- Conducting allergy tests
- Consultation with an otolaryngologist
- Medication therapy (antihistamines)
- Psychotherapy and stress management
- Lifestyle adjustments (e.g., breathing practices)
Complications
Sensitivity to odors can lead to various complications that negatively affect the patient’s quality of life. One of the main complications is constant psycho-emotional tension. People experiencing heightened sensitivity to odors may suffer from anxiety, irritability, and even depression, especially if their daily lives are significantly hindered by unpleasant smells. This can affect their ability to perform routine tasks, such as work or interacting with others.
Another potential issue is the exacerbation of chronic conditions such as asthma or allergic rhinitis. Exposure to strong or unpleasant odors can trigger exacerbations and worsen the overall condition of the patients. This, in turn, can lead to the development of resistance to drug therapy and a worse health prognosis. Therefore, it is important not only to diagnose heightened sensitivity to odors but also to properly manage the symptoms to avoid these complications.
Moreover, heightened sensitivity to odors can affect social contacts and professional activities. People suffering from this symptom may avoid public places, which can lead to social isolation. It is important to consult with a doctor to assess possible complications and develop a symptom management plan.
- Psycho-emotional disorders (anxiety, depression)
- Exacerbation of chronic diseases (asthma, allergies)
- Social isolation and reduced quality of life
- Deterioration of professional activity
FAQ
How to deal with increased sensitivity to smells?
To combat increased sensitivity to smells, it’s important to identify and eliminate the triggers that cause discomfort. This may include avoiding certain odors, such as perfume, cleaning products, or strong food items. It’s also recommended to maintain clean air in the room through ventilation and using air purifiers. In some cases, relaxation and stress management methods, such as meditation and yoga, can be beneficial in reducing overall sensitivity. If the problem persists, it is advisable to consult a specialist for advice and treatment.
What are the main reasons for increased sensitivity to smells?
Increased sensitivity to smells, or hyperosmia, can occur for various reasons, including hormonal changes, upper respiratory infections, neurological disorders, or allergic reactions. This condition is often observed in women during pregnancy or menstruation when hormone levels fluctuate. Additionally, certain medications can lead to heightened olfaction, including drugs that affect the central nervous system. It is important to note that the cause of hyperosmia can be individual for each person, and if it occurs, one should consult a doctor for an accurate diagnosis.
How does stress affect sensitivity to smells?
Under the influence of stress, a person may experience changes in the functioning of the nervous system, which, in turn, may lead to increased sensitivity to smells. Stress can enhance the perception of various aromas, including unpleasant and sharp odors, due to the activation of certain areas of the brain associated with processing sensory information. Additionally, stress can alter chemical processes in the body, which may lead to heightened reflexes, including olfactory ones. If stressful situations become regular, this can cause discomfort and negatively impact the quality of life.
How does age affect sensitivity to smells?
Age can have a significant impact on sensitivity to smells. As people age, especially after 60, many begin to notice a decline in their sense of smell, which is linked to the natural aging of the body and a decrease in the activity of olfactory receptors. Elderly individuals may become less sensitive to certain odors, although sometimes hypersensitivity is observed, where they start to perceive even faint scents more intensely. This variability can be exacerbated by factors such as health (for example, the presence of diseases affecting the nervous system) and the living environment, including exposure to pollutants or smoking.
