Children’s eating habits are shaped by far more than just what is placed on their plate. From early feeding practices and food preferences to emotional well-being, digestive health, and the powerful gut–brain connection, appetite in children is influenced by a complex interplay of biological and behavioural factors.
In this conversation with pediatrician Dr Ritu Gupta, we explore these nuances with our expert, gaining insight into common concerns parents face, when to worry, and how thoughtful, age-appropriate guidance can help children develop a healthy relationship with food. Dr Gupta is currently practicing at Priti Nursing and Maternity Home, Prayagraj (Allahabad). She holds an MD in Pediatrics and is a certified NABH assessor.
When a parent says their child “just doesn’t like to eat,” what possible medical or physiological conditions do you consider first?
The pediatric age group extends from newborns to 18 years, so concerns about eating largely depend on the child’s age. If the child is an infant, we often consider whether weaning was delayed or not introduced at the appropriate age of around 6 to 8 months. In such cases, the child may develop a certain resistance or negativity towards eating food.
If an older child presents with a complaint of not wanting to eat, it may simply be due to preferences, liking certain foods and disliking others. This often depends on what parents regularly offer. For instance, if a child has been frequently given fast food, they may be reluctant to eat home-cooked meals.
When parents approach us saying their child is not eating well, the first thing we assess is the child’s age, and then we determine the possible aetiology of the problem. For younger children, we advise parents to introduce new foods patiently and continue offering them even if the child initially refuses. A child may say no several times, before eventually accepting the food, often around the ninth attempt. This process requires a great deal of patience. For older children, it becomes important to counsel both the child and the parents about the nutritional value of different foods, so the child gradually learns to choose what is right for them when they feel hungry.
How can a caregiver differentiate between ordinary spit-ups or acidity and a more serious reflux issue that affects feeding?
Spit-ups are normal; they do not cause any distress to the baby. Baby is usually happy, growing well and they’re just formula feeds or milk feeds that come out of the mouth in a small amount, whereas reflux is a serious disease where the baby is usually in distress, vomits out most of the food and it could also contain blood and leads to weight gain in the baby. So as a medical practitioner, we need to differentiate between spit-ups and reflux and treat it accordingly.
How does untreated constipation change a child’s relationship with food?
Complaints of constipation usually come to us when a child is between one to four years of age. This commonly happens when a child is predominantly on a milk-based diet; due to a lack of fibre, constipation can develop. Another common reason is when a child develops the habit of holding stools because of fear of using the toilet at school, which can also lead to constipation.
If the issue is due to excessive milk intake, we try to introduce more fibre into the child’s diet along with simple lifestyle modifications. These include encouraging the child to go to the toilet after every meal and sit there for at least 10 minutes. We may also start the child on a low dose of lactulose for a longer duration, usually from a week to up to a month, and gradually stop it once the child begins passing stools regularly.
If the cause is related to school, parents need to communicate with the teacher and request that the child be allowed to use the toilet whenever needed. It is also important to request school authorities to ensure that toilets are kept clean and child-friendly.
Are food allergies or intolerances (like milk or gluten sensitivity) common causes of poor appetite among Indian children?
Food allergies and intolerances are an under-recognized cause of low appetite in Indian children. The experience of consuming certain foods can be so uncomfortable that a child may begin to refuse eating altogether. Symptoms can include abdominal pain, nausea, bloating, hives, difficulty swallowing, or heartburn, as seen in conditions such as eosinophilic esophagitis. Some children may develop delayed but severe reactions, including vomiting and diarrhoea, which are characteristic of conditions like FPIES and can sometimes lead to dehydration. Over time, these reactions can significantly affect nutritional intake and growth. Common dietary triggers include cow’s milk, wheat, soy, and nuts. When symptoms are persistent or severe, it is important for parents to seek medical evaluation and guidance.
Sometimes children say “my tummy hurts” or “I feel full” even after one bite. What could that indicate medically, and how can doctors assess that without invasive procedures?
Low appetite in children can be multifactorial:
a) Food preferences: Toddlers are more likely to eat foods they enjoy while rejecting others. Selective eating is often a normal part of growth and development.
b) Morning anxiety: Some children experience nervousness or anxiety before school, which can reduce their appetite in the morning. This usually improves as the day progresses.
c) Recurrent abdominal discomfort: This is commonly seen during adolescence and may occur multiple times a day without any serious underlying cause.
d) Infections: During illnesses or when a child has digestive symptoms such as diarrhoea, appetite often decreases. In such cases, a doctor must carefully assess the child’s age, associated symptoms, food preferences, stool pattern and timing, and the frequency of abdominal pain to determine the underlying cause.
Do children with gut discomfort actually experience emotional distress that amplifies feeding issues?
The gut–brain axis is a vital two-way communication system between the gut microbiome and the brain. This ongoing dialogue takes place through the vagus nerve, the circulatory system, and hormonal pathways, allowing constant exchange of information. In many ways, the gut is one of the brain’s most important communication partners—almost like a “best friend” within the body. This close relationship helps explain why a child’s emotional state can directly influence appetite. Positive emotions such as happiness or excitement may stimulate hunger, while emotions like sadness, anger, or stress can suppress it. By integrating emotional, neurological, and digestive signals, the gut–brain axis plays a key role in regulating how and when children eat.
In your clinical experience, what proportion of “fussy eaters” you see turn out to have underlying physical causes versus purely behavioural reasons?
Although picky eating is often linked to behavioural factors, only about 20–40% of children with picky eating habits have more serious feeding concerns. Common behavioural reasons include fear of trying new foods, using food refusal as a way to express independence, or insisting that parents prepare only familiar and preferred meals. Some children may simply dislike certain foods, particularly bitter or strongly flavoured vegetables such as bitter gourd or bottle gourd.
However, picky eating can sometimes indicate underlying issues. Digestive problems like constipation or acid reflux may make eating uncomfortable or painful, leading to food avoidance. In certain cases, anxiety or conditions such as autism spectrum disorder may also be associated with feeding difficulties. Nutritional deficiencies can further affect eating behaviour and appetite, especially when iron or zinc levels are low.
How can parents manage picky eating in children?
Managing picky eating requires a patient, consistent, and non-judgmental approach. Parents should avoid blaming themselves, as selective eating is common in children and often improves with time. Introducing solid foods at the appropriate age, especially in milk-fed infants, and starting with nutrient-dense, age-appropriate foods, lays a strong foundation.
Children learn by observing, so leading by example and eating a variety of healthy foods as a family is essential. It is equally important not to fall into the trap of offering less healthy alternatives when a child refuses a meal, as this can reinforce selective eating habits. Avoid snacking before meals to allow natural hunger cues to develop. If a child refuses to eat, stay calm, remove the pressure, and offer the food again at the next scheduled mealtime. Over time, this consistent and relaxed approach helps children develop healthier eating behaviours and a more positive relationship with food.
How should parents prepare before visiting a doctor about feeding issues — what details or observations help you make a better diagnosis?
Before visiting a doctor for feeding concerns, parents can prepare by closely observing and noting their child’s eating patterns and behaviours. Details such as what the child eats, how much, and how long mealtimes last are very helpful. Parents should note any signs of discomfort during or after meals, including gagging, coughing, bloating, constipation, vomiting, or irritability. Tracking when the feeding issue started and whether it is consistent or situation-specific (for example, only with certain textures or foods) can offer valuable clues. Information about the child’s growth, recent illnesses, medications, and sleep patterns also supports better assessment. It is useful to observe the child’s appetite cues, food preferences, and any strong reactions to new foods. Parents may also note environmental factors like mealtime routines, distractions, or stress around feeding. Bringing short videos of mealtimes, if possible, can further help the doctor understand the feeding challenge and guide a more accurate diagnosis and care plan.
There’s a growing conversation around the microbiome and appetite regulation. Are you seeing any early research or practical connections in children yet?
Through the gut-brain axis, gut dysbiosis—an imbalance in the gut microbiome—can significantly influence children’s eating habits. Studies reveal that a healthy, balanced gut microbiota not only improves digestion but also helps youngsters develop a favourable relationship with food. Children are better able to control their appetite and react to hunger and fullness cues when their gut flora is in balance.
Finally, what message would you like to give parents who are torn between “it’s just a phase” and “something might be wrong”?
Parents should first reflect on snacking habits—frequent snacks before meals can significantly reduce a child’s appetite at mealtimes. It is also important to assess what foods are being offered. For example, a child who has been accustomed to a predominantly milk-based or bread-heavy diet may resist meals when vegetables or new foods are suddenly introduced.
In some cases, the concern may not be the child’s intake but parental perception—the child may actually be eating adequately for their age. Therefore, it is essential to determine whether there is a true feeding problem or simply a mismatch in expectations.
A careful feeding history should include details about mealtimes, snacking patterns, food variety, and the emotional environment around meals. Understanding whether meals have become a power struggle or a way for the child to assert control is equally important. Along with this, monitoring the child’s weight and growth pattern, combined with a thorough dietary and behavioural history, helps in accurately identifying the underlying issue and guiding appropriate management.
