Parents often assume that a child refusing food is simply being “picky,” stubborn, or difficult. However, many feeding challenges stem not from behaviour, but from the child’s sensory experience of food—how it smells, tastes, feels, and is perceived inside the nose, mouth, and throat. When a child cannot smell well, struggles with chronic congestion, or experiences discomfort while chewing or swallowing, food naturally becomes less appealing, even distressing. Yet these medically driven issues are frequently overlooked, leading families to rely on pressure-based feeding, which only worsens frustration on both sides.
In this exclusive interview with THIP Media, Dr Shivali Agrawal, ENT specialist, Moolchand Hospital, Delhi, explains how these sensory and structural issues directly impact appetite, food preferences, and mealtime behaviour in children. With deep clinical experience in ENT health, she highlights why early identification matters—and how the right treatment can restore a child’s natural joy for eating while easing stress for the entire family.
Many parents assume picky eating is just a behavioural habit. How often does poor appetite actually begin in the nose, mouth, or sensory system rather than in behaviour?
While behavioural picky eating is common in paediatric clinics, studies show that 30–40% of persistent poor-appetite cases referred to ENT clinics actually have a primary or contributing sensory or structural cause in the nose, mouth, or oropharynx—rather than being purely behavioural. Major underlying factors include tonsillar or adenoid hypertrophy, nasal allergies, dental issues, GERD, and several other ENT-related conditions.
Why is it important for parents to consider medical or sensory reasons early instead of attributing eating issues to stubbornness?
Identifying underlying medical conditions is crucial, as many can be serious and time-sensitive. Issues such as gastroesophageal reflux (GERD), food allergies or intolerances, eosinophilic esophagitis (EoE), and swallowing disorders (dysphagia) may cause pain, nausea, or choking sensations during eating. When these are mistakenly dismissed as behavioural problems, they often go undiagnosed, leading to failure to thrive, nutritional deficiencies, and even esophageal damage. Early evaluation—through allergy testing, pH studies, or endoscopy—can help identify the cause and prevent long-term complications. A major concern is the mislabeling of poor eating as “stubbornness”, which harms parent–child trust. Pressure tactics such as bribes, threats, or force-feeding intensify power struggles and anxiety, creating a vicious cycle of refusal. Early identification also helps prevent secondary issues. Prolonged avoidance of food can lead to micronutrient deficiencies (e.g., iron or zinc causing cognitive delays), speech delays (due to limited oral-motor practice), and social withdrawal (from avoiding shared meals).
How do you explain how taste and smell work together in children to make food enjoyable?
There is a clear difference between taste and flavour. Flavour is the combination of taste + smell, and this is what truly makes food enjoyable. When we have a cold, we lose our sense of smell, so food feels bland—right?
- Smell (Olfaction): When we chew, food releases tiny odor molecules that travel through the retronasal route to the olfactory epithelium—a cluster of smell receptors deep in the nose. In children, smell is especially important because 80–90% of what they perceive as “taste” actually comes from smell.
- Impact on Picky Eating: Children with frequent colds, nasal allergies, or enlarged adenoids often have blocked smell pathways. With reduced flavour perception, they naturally show less interest in food, which is often mistaken as picky eating.
- Texture & Smell Sensitivity: Some children are hypersensitive to strong food odors (like fish or broccoli), which can make mealtimes overwhelming and stressful.
- Developmental Milestones: Smell preferences begin early in life. Familiar and pleasant food aromas—like home-cooked meals—help create a sense of emotional comfort and safety around eating.
What simple diagnostic steps or tests do you recommend before labelling a child as a “picky eater”?
When to See an ENT: You should consider an ENT evaluation if your child:
- Constantly says food “tastes bad”
- Has chronic nasal congestion
- Avoids strong-smelling foods
These signs may indicate adenoid hypertrophy, sinus issues, or olfactory dysfunction rather than simple picky eating. A child who is just selective about flavours or colours is usually showing behavioural picky eating.
However, a child who gags, coughs, or refuses entire groups of food textures—especially if they were previously a good eater—should not be labelled “just picky.” They deserve at least a flexible laryngoscopy and often a swallow study (VFSS or FEES) before ruling out medical issues. Early detection of swallowing or airway problems can prevent aspiration pneumonia and greatly improve feeding outcomes.
How to Differentiate: ENT Issue vs. Typical Picky Eating
Typical / Behavioural Picky Eating:
- Accepts 10–30 foods
- Gradual improvement over months
- Eats when truly hungry
- Maintains normal growth and weight
Possible ENT / Medical Issue:
- Accepts fewer than 10 foods (often fewer than 5)
- Sudden onset or rapid worsening
- Appears hungry but still refuses to eat
- May show poor weight gain or weight loss
Some parents say their children find smells “too strong” or complain that “everything smells weird.” What medical or sensory issues might explain this heightened sensitivity?
Children with Autism Spectrum Disorder (ASD), Sensory Processing Disorder (SPD), or ADHD may experience significant sensory challenges during eating—such as oral hypersensitivity (gagging at textures), smell aversions, and anxiety due to unpredictability of food. These are involuntary neurological responses, not misbehaviour. Forcing a child to eat can worsen anxiety, deepen food aversions, and create long-term mealtime trauma. Instead, sensory-based feeding therapy helps the child gradually build tolerance in a safe, regulated way.
When Food Suddenly Tastes ‘Disgusting’ or Strange:
- Metallic, chemical, rotten, or foul tastes: Often indicates dysgeusia, which is frequently reversible when the underlying cause is treated (e.g., zinc deficiency, reflux, nerve inflammation, medications).
When Smells Become Abnormally Strong or Distorted
- “All smells are suddenly too strong”: May suggest post-viral olfactory hypersensitivity (common after COVID, flu, RSV, or mononucleosis).
- “Everything smells rotten, chemical, or like sewage”: Classic parosmia, the most common after-effect of post-viral anosmia.
- “Certain smells make my child gag or feel sick”: Could be trigeminal nerve irritation secondary to chronic sinusitis or allergic rhinitis.
Oversensitivity to perfume, petrol, cleaning agents: May occur with hyperosmia seen in migraine or after a minor head injury.
Smells are too strong on only one side of the nose: Suggests a unilateral nasal issue such as a polyp, foreign body (common items: pea, bean, Lego), or—rarely—an early tumour.
Are there safe, gentle therapies—like nasal hygiene routines, smell training, or oral sensory exercises—that can help children rediscover the joy of eating?
Small sensory adjustments at home can make a big difference in your child’s eating confidence. Try these techniques:
Clear the Nose: Use saline sprays, saline gel, or a humidifier if your child has a stuffy nose—this helps restore smell and naturally improves appetite.
Fun Smell Games: Play “guess the scent” using safe foods like apple, cinnamon, strawberry jam, or peanut butter. Let your child sniff each for 10–20 seconds, twice a day, to strengthen smell–taste connections.
Introduce Gradually: Pair new foods with familiar, comforting smells—like adding cheese to sandwiches or mixing vegetables into rice—to ease acceptance and reduce anxiety around new flavours.
How can parents support sensory recovery at home while medical causes are being treated?
Gentle, consistent sensory work can rebuild a child’s comfort and confidence with food:
- Olfactory (Smell) Training — even if smell is only partially reduced: Practice twice daily (morning and before dinner) for 3–6 months to strengthen smell pathways and improve flavour perception.
- Taste Re-Training — very effective for dysgeusia or “everything tastes metallic”: Do 5-minute taste games once or twice a day with the five basic tastes: sweet, salty, sour, bitter, and umami. The goal is exposure and familiarity—not swallowing at first.
- Oral-Motor & Tactile Desensitisation: Useful after surgery or prolonged mouth-breathing. Slowly introduce different textures and temperatures to reduce gagging and improve eating comfort.
- Reduce Negative Sensory Triggers That Make Eating Unpleasant: Manage issues like post-nasal drip, mouth-breathing, dental discomfort, or nasal congestion to make mealtimes smoother and less stressful.
How can parents recognise when it’s time to see an ENT specialist rather than continue coaxing or experimenting with food at home?
If your child is hungry but distressed and still refuses foods they once loved, trust your instincts. Get their nose, sinuses, ears, and taste–smell pathways evaluated. The earlier we identify and treat the medical cause, the faster—and more fully—their eating returns, reducing the risk of it becoming a long-term issue.
We’re here to help, not judge. We see children like this every single day, and most improve dramatically once the underlying sensory problem is addressed. Many parents spend months or even years assuming it’s “just behavioural,” when the child is actually struggling with loss of smell, metallic or rotten tastes, or constant throat mucus—issues that simply cannot be fixed with food chaining or rewards.
