When Should You Worry?

If your child has normal weight and height (for their age), then there might not be a reason to worry, as some children with a small build might have lesser food requirements and, therefore, a lesser appetite(1). But if your child is older and the loss of appetite is sudden, accompanied by weight loss, then you may consult a pediatrician to identify the cause and correct it.

While parents should offer a variety of nutritious food options to children, they should also allow them to decide how much and what to eat (1).

Possible Reasons For Loss Of Appetite In Children

If your child is always tired and irritable, it might be linked to a lack of appetite and adequate nutrition. Here are a few possible reasons why children might lose their appetite:

1. Slow growth rate

Changes in growth and development can cause an appetite slump in children. During the first year, children grow rapidly. But after that, the growth slows down, and they may eat less food. During this period, a decline in appetite is perfectly normal. In fact, in the second year of life, children only need to put on 2.3kg and 12 cm as opposed to 7 kg and 21 cm in the first year (1).

2. Sickness

Children may experience a significant loss of appetite as a result of certain allergies, chronic illnesses, or infections. If your child is suffering from a sore throat, stomach flu, diarrhea, headache, fever, or other symptoms, then they may eat less than what they usually do (2). Thankfully, most children regain their appetite when they get better.

3. Stress

Stress can have many negative effects, including loss of appetite, on young children (3). If you find that your child is losing interest in eating or having a hard time sleeping, then they may be suffering from stress. To address your child’s poor appetite, you need to identify the cause of stress and alleviate it. Some common causes of stress during childhood are:

  • Family issues such as the death of a family member, loss of a pet, birth of a sibling, or changes in family dynamics
  • Bullying
  • Inability to cope with academic pressure and the impractical expectations of parents

4. Depression

Depression could be another reason for a child’s loss of appetite. Most parents mistake depression for sadness. But sadness and depression are not the same. Feelings of sadness go away with time, but depression does not. Depression not only makes the child sad but also interferes with their normal life.

According to the Centre for Disease Control and Prevention (CDC), depression is one of the most commonly diagnosed mental health issues in children. From 2016 to 2019, the prevalence of diagnosed depression among US children between 3 and 17 years was 4.4%.

If your child shows a significant lack of interest in activities that they previously enjoyed, then they may be depressed. A change in eating habits could be a strong indicator of depression. It is advisable to seek medical advice if you are concerned about your child’s mental health (4).

5. Anorexia nervosa

Sometimes, in a bid to emulate/ copy their screen idols and for several other reasons, children develop a psychological aversion to eating. They reduce their dietary intake or avoid eating for as long as possible. Even when they eat, they develop food preferences or become picky eaters, choose low-fat foods, and later feel guilty about eating them. Genetics, brain chemical imbalances, and developmental issues can also cause anorexiaiAn eating disorder and mental health condition characterized by abnormally low weight and fear of weight gain nervosa.
