Signs and Symptoms of Olfactory and Gustatory Difficulties

Signs and Symptoms

It is essential for professionals and caregivers to be able to identify when somebody is having olfactory and gustatory processing difficulties. As well as sensory profiling people to identify their sensory difficulties, being able to recognise the signs of sensory needs is vital for effective management.

Gustatory Seeking

Gustatory seeking behavior refers to a tendency to actively seek out and explore tastes, flavors, and food-related experiences. This behavior can manifest in various signs and symptoms, particularly in individuals who have heightened sensory seeking tendencies.

Here are some signs and symptoms of gustatory sense seeking:

  1. Constantly Seeking New Flavors: Individuals may constantly seek out new and diverse flavors and foods to satisfy their curiosity and desire for sensory stimulation. They may enjoy experimenting with different cuisines, spices, and ingredients to experience novel tastes and textures.
  2. Preference for Intense Flavors: Gustatory seekers often have a preference for bold and intense flavors that provide strong sensory experiences. They may enjoy foods that are spicy, sour, sweet, or bitter, and may seek out foods with complex flavor profiles and unique taste combinations.
  3. Craving for Sensory-rich Foods: Individuals with gustatory seeking tendencies may have a strong craving for sensory-rich foods that provide intense gustatory experiences. They may enjoy foods with varied textures, temperatures, and mouthfeel sensations, such as crunchy, creamy, or chewy foods.
  4. Eating Excessively or Quickly: Gustatory seekers may eat excessively or quickly in their quest for sensory stimulation. They may have a tendency to overeat or indulge in large quantities of food, particularly foods that provide strong gustatory sensations.
  5. Preference for Spicy or Flavorful Foods: Individuals with gustatory seeking tendencies may have a preference for spicy or flavorful foods that provide a sensory "kick." They may enjoy foods with added spices, seasonings, or condiments to enhance the taste and intensity of flavors.
  6. Engagement in Food-related Activities: Gustatory seekers may actively engage in food-related activities such as cooking, baking, or exploring food markets and culinary events. They may enjoy the process of preparing and experimenting with different foods to create sensory-rich experiences.
  7. Eating non-food items- Seeking and mouthing/digiesting non-food items such as clothing, mud/sand, stationary items, clothes washing tablets, play dough, bodily fluids and excrement and much more.
  8. Participation in Food Challenges or Eating Contests: Some gustatory seekers may participate in food challenges or eating contests as a way to experience extreme gustatory sensations and push their sensory boundaries. They may enjoy the thrill of testing their taste buds and competing with others in food-related activities.
  9. Not recognising the feeling of fullness: Gustatory seekers may also have difficulties with their interceptive sense which allows you to know if you feel full or not. Individuals may exsesively eat, eat fast or eat regularly.
  10. Heightened Sensitivity to Taste: Individuals with gustatory seeking tendencies may have a heightened sensitivity to taste and may be able to detect subtle flavor nuances that others may overlook. They may enjoy savoring and appreciating the intricacies of different flavors and taste profiles.

It's important to note that gustatory seeking behavior can vary in intensity and expression among individuals and may be influenced by factors such as genetics, culture, and personal preferences. While gustatory seeking behavior can be a natural and enjoyable aspect of food exploration, it's essential to maintain a balanced and healthy approach to eating and to be mindful of individual dietary needs and preferences.

Gustatory Avoiding

Gustatory sense avoiding behavior refers to a reluctance or avoidance of certain tastes, flavors, or food-related experiences due to discomfort, aversion, or anxiety. While gustatory seeking behavior involves actively seeking out novel tastes and flavors, gustatory avoiding behavior involves avoiding or limiting exposure to certain foods or flavors.

Here are some signs and symptoms of gustatory sense avoiding behavior:

  1. Limited Food Choices: Individuals may have a limited range of foods they are willing to eat, avoiding certain tastes, flavors, or textures altogether. They may stick to a narrow selection of familiar foods and be resistant to trying new or unfamiliar foods.
  2. "Picky Eating": Gustatory avoiders may exhibit "picky" eating behaviours characterised by strong preferences or aversions to specific tastes, textures, or food groups. They may refuse to eat foods with certain flavors, smells, or appearances, leading to limited dietary variety. It is important to note, that this may not be "picky eating" and in fact maybe a sign of ARFID (Avoidant Restrictive Food Intake Disorder). More information on this is one the ARFID page.
  3. Avoidance of Certain Foods or Ingredients: Individuals may actively avoid or refuse to eat foods that they find unappealing or aversive. They may express disgust or discomfort at the thought of consuming certain foods, ingredients, or food combinations.
  4. Reluctance to Try New Foods: Gustatory avoiders may be hesitant or reluctant to try new foods or flavors, even when encouraged to do so. They may express anxiety or apprehension about trying unfamiliar foods, fearing negative reactions or unpleasant tastes.
  5. Physical Discomfort or Nausea: Exposure to certain tastes or flavors may elicit physical discomfort or nausea in gustatory avoiders. They may experience sensations of nausea, gagging, or vomiting in response to specific tastes or food odors.
  6. Limited Social Dining Experiences: Gustatory avoiders may limit their participation in social dining experiences or food-related activities due to their aversion to certain tastes or flavors. They may avoid restaurants, social gatherings, or events where they anticipate being exposed to foods they dislike. They may also take a lot longer to eat because they may take small bites, rest in-between mouthfuls and/or over chew food.
  7. Rigid Eating Habits: Individuals with gustatory avoiding behavior may exhibit rigid eating habits and routines to avoid exposure to aversive tastes or flavors. They may prefer to prepare their own meals or eat alone to maintain control over their food choices.
  8. Preference for Plain or Bla​nd Foods: Gustatory avoiders may gravitate towards plain or bland foods (the toddler diet) with muted flavours and minimal seasoning. They may prefer foods that are mild in taste and avoid foods with strong or complex flavors.
  9. Discomfort in Food-Related Situations: Gustatory avoiders may experience discomfort or anxiety in food-related situations, such as dining out or attending social gatherings where food is served. They may feel self-conscious or embarrassed about their eating preferences or limitations.
  10. Impact on Nutritional Status: Gustatory avoiding behavior can impact individuals' nutritional status and dietary quality, leading to imbalances or deficiencies in essential nutrients. Limited dietary variety may result in inadequate intake of nutrients needed for optimal health and well-being.

It's important to recognise that gustatory avoiding behavior can vary in severity and may be influenced by factors such as sensory sensitivities, past food-related experiences, and cultural or familial influences. Encouraging individuals to explore new foods at their own pace, providing positive reinforcement for trying new flavors, and creating a supportive and non-judgmental food environment can help individuals with gustatory avoiding behavior gradually expand their food preferences and experiences.

Olfactory Seeking

Olfactory seeking behaviour refers to the tendency to actively seek out and explore smells, fragrances, and olfactory experiences. Individuals who engage in olfactory seeking behavior may have a heightened interest in and appreciation for scents and may actively seek opportunities to experience a variety of smells.
