Childhood Obesity: Causes, Risks and Treatment Options

Childhood obesity is a complex health condition that can affect a young person's physical health, emotional wellbeing and quality of life.

It is not simply a matter of eating too much or exercising too little.

A child's weight can be influenced by genetics, appetite regulation, food environment, sleep, mental wellbeing, family circumstances, medical conditions, medicines and physical activity.

For some children and teenagers, family-based changes to nutrition, activity and daily routines may be enough to improve their health and weight trajectory. Others, particularly young people living with significant obesity or obesity-related health problems, may benefit from more structured specialist support.

This is why 24 HR Pharmacy is launching its Family Healthy Weight Programme: a specialist, family-centred service designed to support children and adolescents living with obesity and their families.

Rather than approaching childhood obesity through medication alone, the programme brings together a multidisciplinary team including a specialist obesity prescriber, dietitian and paediatrician. The aim is to assess the whole young person and create an individualised plan that considers nutrition, growth, physical health, lifestyle and, where clinically appropriate, medical treatment.

This guide explains the causes of childhood obesity, potential health risks, treatment options available in the UK and how the 24 HR Pharmacy Family Healthy Weight Programme provides specialist multidisciplinary support.

What Is Childhood Obesity?

Childhood obesity refers to excess body weight that may increase a young person's risk of health problems.

Assessing weight in children and teenagers is different from assessing weight in adults.

Adults are commonly assessed using fixed BMI thresholds. Children are still growing and developing, so healthcare professionals need to consider factors such as:

• age;

• sex;

• height and weight;

• BMI in relation to age and sex;

• growth trajectory;

• stage of development;

• medical history;

• and overall health.

A young person should therefore not simply be assessed using adult BMI thresholds.

Understanding how their weight has changed alongside their growth and development provides a much more useful clinical picture.

What Causes Childhood Obesity?

There is rarely one single cause.

Childhood obesity usually develops through a combination of biological, environmental, behavioural, social and psychological factors.

This is important because effective treatment should investigate what is contributing to a young person's weight rather than simply telling them to "eat less and exercise more."

Genetics and Family History

Genetics can influence:

• appetite;

• metabolism;

• hunger signals;

• feelings of fullness;

• fat storage;

• and susceptibility to weight gain.

Having a strong family history of obesity does not mean that a child will inevitably develop obesity, but it may mean their biology makes maintaining a healthy weight more challenging.

Food Environment

Children generally do not have complete control over the food available at home.

Their eating patterns can be influenced by:

• portion sizes;

• sugary drinks;

• frequent snacks;

• takeaway meals;

• highly energy-dense foods;

• irregular mealtimes;

• eating in front of screens;

• and the availability of healthier alternatives.

For this reason, childhood weight management works best when the family is involved.

The objective should not be to place one child on a restrictive diet while everyone else continues as normal.

Physical Activity

Young people may spend significant amounts of time sitting because of:

• schoolwork;

• gaming;

• television;

• smartphones;

• social media;

• and travelling by car.

Increasing movement can help, but exercise should not be used as punishment for eating.

Walking, cycling, swimming, dancing, football, active play and other activities can all contribute.

Finding something the young person actually enjoys is often more sustainable than prescribing a rigid exercise programme.

Sleep

Sleep can also affect weight.

Insufficient or disrupted sleep may influence appetite, energy levels and eating behaviour.

At the same time, obesity can increase the risk of conditions such as obstructive sleep apnoea.

This can create a cycle in which poor sleep affects weight management while excess weight contributes to poorer sleep.

Emotional and Psychological Factors

Young people may sometimes use food to cope with:

• stress;

• anxiety;

• boredom;

• loneliness;

• bullying;

• low mood;

• or difficulties at school or home.

Body image and weight stigma can add another layer of distress.

These issues should not be dismissed as a lack of willpower.

Where emotional or psychological factors are contributing to eating behaviour or wellbeing, they need to form part of the overall assessment and care plan.

Medicines and Medical Conditions

Certain medicines and medical conditions may contribute to weight gain.

Depending on the young person's history, clinicians may need to consider:

• current medicines;

• endocrine conditions;

• genetic disorders;

• mobility problems;

• neurological conditions;

• and other underlying health problems.

One advantage of a multidisciplinary service is that weight can be considered alongside the child's wider medical history rather than in isolation.

Why Is Childhood Obesity a Health Concern?

The purpose of addressing childhood obesity is health, not appearance.

Obesity during childhood and adolescence can be associated with an increased risk of several physical and psychological health problems.

These can include:

• type 2 diabetes;

• high blood pressure;

• abnormal cholesterol levels;

• fatty liver disease;

• obstructive sleep apnoea;

• joint and mobility problems;

• and psychological difficulties.

Not every young person with obesity will develop these conditions, but identifying potential complications is an important part of specialist assessment.

The Emotional Impact of Childhood Obesity

Physical health is only part of the picture.

Children and teenagers living with obesity may experience:

• bullying;

• teasing;

• weight stigma;

• low confidence;

• poor body image;

• anxiety;

• low mood;

• social isolation;

• or reluctance to participate in sport and social activities.

This is one reason conversations around childhood weight need to be handled carefully.

The goal should never be to make a young person feel ashamed of their body.

Instead, discussions should focus on areas such as:

• health;

• energy;

• fitness;

• sleep;

• mobility;

• confidence;

• nutrition;

• and feeling well.

Can Childhood Obesity Continue Into Adulthood?

It can.

Young people living with significant obesity may have an increased likelihood of continuing to experience obesity and associated health risks later in life.

Early intervention provides an opportunity to establish healthier patterns around:

• food;

• activity;

• sleep;

• emotional wellbeing;

• and long-term health.

Importantly, successful treatment does not always mean rapid weight loss.

Because children and teenagers are growing, there may be situations where improving the weight and BMI trajectory is more appropriate than pursuing large reductions on the scales.

This is another reason specialist assessment matters.

Introducing the 24 HR Pharmacy Family Healthy Weight Programme

The 24 HR Pharmacy Family Healthy Weight Programme is being developed specifically to provide structured, specialist support for children and adolescents living with obesity and their families.

It is different from a standard adult online weight-loss service.

Childhood and adolescent obesity requires consideration of:

• growth and development;

• nutrition;

• physical health;

• family circumstances;

• psychological wellbeing;

• safeguarding;

• obesity-related health risks;

• and, where relevant, age-appropriate medical treatment.

For that reason, our programme uses a multidisciplinary approach.

A Multidisciplinary Team

The Family Healthy Weight Programme brings together professionals with complementary areas of expertise, including a:

Specialist Obesity Prescriber

The specialist obesity prescriber assesses whether medical treatment should form part of the young person's overall weight-management plan.

Their role may include:

• reviewing medical history;

• assessing previous weight-management attempts;

• reviewing current medicines;

• identifying potential contraindications;

• considering whether prescription treatment is clinically appropriate;

• discussing potential benefits and risks;

• and providing ongoing treatment reviews where medication is used.

Prescription medication is not automatically recommended simply because a young person is living with obesity.

It is one potential component of specialist care for appropriately selected adolescents.

Dietitian

Nutrition during childhood and adolescence requires particular care because the body still needs sufficient energy and nutrients for normal growth and development.

Our dietitian can help families develop realistic, nutritionally appropriate eating habits rather than relying on crash diets or unnecessarily restrictive eating plans.

Support may consider:

• meal structure;

• portion sizes;

• protein intake;

• fruit and vegetables;

• fibre;

• snacks;

• sugary drinks;

• eating patterns;

• family meals;

• and practical changes that can be maintained at home.

The emphasis is on building a healthier relationship with food while supporting the young person's nutritional requirements.

Paediatrician

The involvement of a paediatrician is particularly important because children and adolescents are not simply smaller adults.

A paediatric assessment can consider the young person's weight alongside their:

• growth;

• development;

• medical history;

• existing health conditions;

• obesity-related complications;

• and overall physical wellbeing.

Where appropriate, further assessment or investigation may be recommended.

Together, these professionals allow the programme to look beyond the number on the scales and consider the young person's health more comprehensively.

What Does the Family Healthy Weight Programme Involve?

Every young person is different, so the programme is designed around individual assessment rather than a one-size-fits-all diet or treatment.

1. Initial Assessment

The starting point is understanding the young person's health and circumstances.

Assessment may consider:

• age;

• height and weight;

• growth and weight trajectory;

• relevant medical history;

• family history;

• current medicines;

• previous weight-management attempts;

• eating patterns;

• physical activity;

• sleep;

• and emotional wellbeing.

This helps the multidisciplinary team identify areas that may need further attention.

2. Dietetic Assessment and Family Nutrition Support

Rather than focusing exclusively on calories, dietetic support considers whether the young person is receiving the nutrition needed for healthy development.

The dietitian can work with the family to establish practical changes that fit everyday life.

This is important because parents and carers usually influence:

• food shopping;

• meal preparation;

• portion sizes;

• mealtimes;

• snacks;

• and household routines.

Making changes as a family can prevent the young person from feeling singled out.

3. Paediatric Review

Where appropriate, the paediatrician can assess the young person's wider health and development and consider whether obesity may already be affecting their physical health.

This may be particularly relevant where there are concerns such as:

• rapid weight gain;

• excessive tiredness;

• heavy snoring;

• breathing pauses during sleep;

• high blood pressure;

• mobility difficulties;

• symptoms of diabetes;

• or other medical concerns.

4. Specialist Obesity Prescriber Review

For some adolescents, lifestyle and nutritional intervention may be sufficient.

For others with clinically significant obesity, the multidisciplinary team may consider whether prescription weight-management medication could form part of the treatment plan.

Any decision to prescribe should be based on the young person's individual circumstances, the licensed indication of the medicine and a careful assessment of benefits and risks.

5. Personalised Healthy Weight Plan

Following assessment, the family can be given a plan appropriate to the young person's needs.

This may involve:

• nutrition changes;

• family-based lifestyle changes;

• increased physical activity;

• sleep improvements;

• behavioural strategies;

• clinical monitoring;

• and, where clinically appropriate, prescription treatment.

The objective is to build changes that can realistically be sustained.

6. Ongoing Follow-Up

Childhood obesity management should not end after a single consultation.

Ongoing reviews allow the clinical team to consider:

• growth;

• weight and BMI trajectory;

• nutritional intake;

• activity;

• sleep;

• wellbeing;

• treatment adherence;

• side effects where medication is used;

• and progress towards agreed health goals.

The plan can then be adjusted as the young person's needs change.

Family-Based Lifestyle Support

Family involvement is central to the programme.

Instead of placing one young person on a restrictive "weight-loss diet", households can work towards healthier routines together.

Changes might include:

• preparing more balanced meals;

• reducing sugary drinks;

• increasing vegetables and fruit;

• choosing appropriate portion sizes;

• reducing frequent takeaway meals;

• making nutritious snacks readily available;

• and creating more consistent mealtimes.

This makes healthy changes feel like a family approach rather than a punishment directed at one child.

Nutrition Without Crash Dieting

Children and teenagers need appropriate nutrition for:

• growth;

• puberty;

• bone development;

• brain development;

• hormones;

• and muscle development.

Highly restrictive diets can therefore be inappropriate.

Our Family Healthy Weight Programme places dietetic support at the centre of care so nutritional changes can be tailored to the young person's needs.

Making Physical Activity Sustainable

Movement should ideally be something the young person can enjoy.

Options may include:

• football;

• swimming;

• dancing;

• cycling;

• walking;

• martial arts;

• age-appropriate gym activities;

• or active games.

A young person who dislikes competitive sport does not need to become an athlete.

The aim is to find realistic ways to increase movement and reduce prolonged sedentary time.

When Might Weight-Loss Medication Be Considered?

Prescription weight-management medication is not appropriate for every child or teenager.

Where medication is considered, it should be part of a specialist treatment programme, not a substitute for nutrition, activity and family support.

Factors that may need to be considered include:

• age;

• severity of obesity;

• weight and growth trajectory;

• obesity-related health problems;

• previous interventions;

• medical history;

• current medicines;

• psychological wellbeing;

• nutritional status;

• and whether the medicine is licensed for the young person's age group.

The decision should be individualised by appropriately qualified clinicians.

Wegovy® and Adolescents

Injectable Wegovy (semaglutide) is licensed in the UK for weight management in certain adolescents aged 12 years and over with obesity, subject to the licensed eligibility criteria.

Wegovy is a GLP-1 receptor agonist. It acts on pathways involved in appetite regulation and can help:

• reduce hunger;

• increase feelings of fullness;

• reduce food intake;

• and support weight management alongside lifestyle intervention.

However, the fact that a medicine has an adolescent licence does not mean every teenager with obesity should receive it.

Within a specialist programme, the obesity prescriber and wider multidisciplinary team can consider whether medication is appropriate for the individual young person.

What About Other Weight-Loss Medicines?

24 HR Pharmacy's existing adult weight-management service offers several prescription treatment options and uses an adult eligibility pathway for people aged 18 and over.

The Family Healthy Weight Programme is a separate specialist pathway.

Medicines available within an adult service should never automatically be assumed to be suitable for children or adolescents.

Any medicine considered for a young person must be assessed according to:

• its licensed age range;

• the young person's clinical circumstances;

• relevant prescribing guidance;

• and specialist clinical judgement.

Why Medication Is Only One Part of the Programme

Modern obesity medicines can be valuable for selected patients, but childhood obesity care should not revolve around medication alone.

Medication cannot replace:

• appropriate nutrition;

• family support;

• physical activity;

• adequate sleep;

• emotional wellbeing;

• and ongoing clinical monitoring.

This is precisely why the Family Healthy Weight Programme brings together a specialist obesity prescriber, dietitian and paediatrician rather than operating as a medication-only service.

The question is not simply:

"Which weight-loss medicine should this young person take?"

The more useful question is:

"What combination of support will give this young person the best opportunity to improve their health?"

When Should Parents Seek Professional Support?

Parents or carers may wish to seek professional advice if:

• their child's weight is increasing rapidly;

• previous family lifestyle changes have not helped;

• weight is affecting mobility or participation in activities;

• there is heavy snoring or suspected sleep apnoea;

• there are symptoms that could suggest diabetes;

• there are concerns about blood pressure or other health problems;

• weight is affecting confidence or emotional wellbeing;

• bullying or weight stigma is occurring;

• eating behaviours are becoming concerning;

• or they are considering prescription weight-management treatment.

Earlier assessment can help identify whether structured support is appropriate.

Eating Disorders and Mental Health

Weight-management treatment must also be sensitive to the possibility of eating disorders or significant psychological distress.

Professional advice should be sought where there are concerns such as:

• binge eating;

• extreme food restriction;

• vomiting after eating;

• compulsive exercise;

• intense fear around food;

• significant body-image distress;

• anxiety;

• depression;

• or self-harm concerns.

In these circumstances, the priority may be appropriate mental-health or eating-disorder assessment rather than active weight reduction.

How Parents Can Talk About Weight

The language used around weight matters.

Try to focus conversations on:

• health;

• strength;

• energy;

• sleep;

• confidence;

• mobility;

• fitness;

• and feeling well.

Avoid:

• blaming the young person;

• repeatedly commenting on their body;

• comparing them with siblings or friends;

• using food as punishment or reward;

• labelling them according to their weight;

• or suggesting their value depends on becoming thinner.

The Family Healthy Weight Programme is intended to provide a supportive, non-judgemental environment for both young people and their families.

How 24 HR Pharmacy Can Help

24 HR Pharmacy already provides clinician-led weight-management care, with assessments reviewed by UK-registered prescribers and ongoing support forming part of its existing model.

The new Family Healthy Weight Programme extends this approach into a dedicated specialist service for young people and their families.

Rather than adapting the standard adult online pathway, the programme is specifically structured around the additional considerations involved in childhood and adolescent obesity.

Our Multidisciplinary Approach

Families can receive coordinated support involving a:

Specialist obesity prescriber — assessing obesity severity, medical suitability and whether prescription treatment may be appropriate.

Dietitian — providing individualised nutritional support appropriate for growth and development while helping the family establish sustainable eating habits.

Paediatrician — considering growth, development, physical health and potential obesity-related medical complications.

Working together allows the team to develop a more complete picture of the young person's health.

Supporting the Whole Family

The word "Family" is important.

Parents and carers have a major influence over food availability, routines, sleep, activity and the wider home environment.

Rather than expecting a young person to manage obesity alone, our approach is designed to help families understand what changes may be useful and how to make them realistically.

Not a Medication-First Service

The Family Healthy Weight Programme is not designed simply as a route to weight-loss medication.

Some young people may benefit primarily from:

• dietetic support;

• healthier family routines;

• activity changes;

• sleep improvements;

• and ongoing monitoring.

For appropriately selected adolescents, prescription treatment may also be considered by the specialist team where clinically appropriate.

The treatment plan depends on the individual.

Frequently Asked Questions

What is the Family Healthy Weight Programme?

The 24 HR Pharmacy Family Healthy Weight Programme is a specialist service for children and adolescents living with obesity and their families.

It uses a multidisciplinary approach involving a specialist obesity prescriber, dietitian and paediatrician to assess the young person's health and develop an individualised weight-management plan.

Is childhood obesity just caused by overeating?

No.

Obesity is complex and can be influenced by genetics, appetite regulation, food environment, activity, sleep, emotional wellbeing, medicines, medical conditions and family circumstances.

Will my child automatically be prescribed weight-loss medication?

No.

The Family Healthy Weight Programme is not a medication-only service.

Prescription treatment may be considered for appropriately selected adolescents where clinically appropriate, but nutrition, family lifestyle, physical health, development and overall wellbeing are all considered.

Why does the programme include a dietitian?

Children and teenagers need adequate nutrition for growth and development.

The dietitian helps families make appropriate dietary changes without relying on extreme restriction or crash diets.

Why is a paediatrician involved?

Children and adolescents are still growing and developing.

A paediatrician can assess weight in the context of growth, development, medical history and potential obesity-related health problems.

Can teenagers use Wegovy?

Injectable Wegovy is licensed for weight management in certain adolescents aged 12 years and over with obesity, subject to its licensed criteria.

Whether it is appropriate for an individual teenager requires specialist clinical assessment.

Can teenagers use adult weight-loss medicines?

An adult medicine should never be assumed to be suitable for an adolescent simply because it is available through the adult 24 HR Pharmacy weight-management service.

The Family Healthy Weight Programme uses a separate specialist pathway, and any medication considered must be appropriate for the young person's age and individual clinical circumstances.

What happens during the programme?

Depending on individual needs, the programme may include assessment of:

• growth and weight trajectory;

• nutrition;

• medical history;

• existing medicines;

• physical health;

• family lifestyle;

• sleep;

• activity;

• emotional wellbeing;

• and previous weight-management attempts.

The multidisciplinary team can then develop an appropriate plan and provide ongoing follow-up.

Do parents need to be involved?

Family involvement is an important part of childhood and adolescent weight management.

Parents and carers can help establish healthier household routines and support the young person between appointments, while the young person's dignity, confidentiality and individual needs remain important.

Final Thoughts

Childhood obesity is a complex health condition and deserves more than a one-size-fits-all diet or an adult weight-loss pathway.

Genetics, appetite, nutrition, physical activity, sleep, emotional wellbeing, family circumstances and medical conditions can all contribute.

Effective treatment therefore needs to look at the whole young person.

That is the principle behind the 24 HR Pharmacy Family Healthy Weight Programme.

Our specialist multidisciplinary approach brings together a specialist obesity prescriber, dietitian and paediatrician to provide coordinated support for young people living with obesity and their families.

For some families, the focus may be nutrition, activity and healthier routines. For others, medical assessment or additional clinical support may be needed. For carefully selected adolescents, age-appropriate prescription weight-management treatment may also be considered where clinically appropriate.

The objective is not simply to make a child lose weight.

It is to help improve health, support normal growth and development, reduce future health risks and give young people and their families practical tools for building healthier habits that can last into adulthood.
