Teen health works best when growth, sleep, movement, mental wellbeing and private conversation are considered together.
Make puberty an ongoing conversation
Children need accurate names for body changes, menstruation, erections, hygiene, attraction, consent, boundaries and online safety before misinformation fills the gap. One formal talk is less useful than many calm, age-appropriate conversations in which questions are allowed.
Normal timing varies, but very early changes, delayed progression or distress about development deserves review. Privacy does not mean secrecy: adolescents should know which concerns can be confidential and when safety requires adult help.
Look at what screens displace
A single universal hour limit cannot describe every teenager’s use. Ask whether screens displace sleep, movement, schoolwork, in-person relationships, meals or emotional recovery. Content, timing and compulsive patterns matter alongside duration.
Family rules work better when adults model them. Protect bedtime, keep devices out of sleep space when possible, agree on interruption-free meals and discuss risky contact, bullying and sexual content without beginning from accusation.
Discuss weight without shame
Weight is influenced by growth stage, food environment, sleep, medicines, mental health, activity, genetics and illness. Humiliation and repeated body comments can worsen eating behaviour and avoidance. Use growth and health measures rather than appearance as the starting point.
A family plan may address meal structure, sugary drinks, movement, sleep and emotional wellbeing. Rapid change, disordered eating, vomiting, fainting, menstrual disturbance, severe snoring or low mood needs a focused assessment rather than a generic diet sheet.
Pediatrics does not end when the child becomes difficult to carry
The adolescent years bring questions that are less visible than fever: puberty, body image, food, inactivity, sleep, screens, aggression, peer influence and communication.
Screen use is a family system
A teenager’s phone cannot be discussed in isolation from sleep, school, exercise, meals, family routines and the adults’ own device behaviour.
Obesity is not solved by shame
The goal is health, not humiliation. Food environment, activity, sleep and sustainable family changes matter more than repeated comments about appearance.
Puberty conversations should begin before embarrassment
Age-appropriate, factual conversations around body changes are easier before the changes become a source of confusion or secrecy.
Common questions from parents
What should parents discuss with children about puberty?
Short answer: Age-appropriate conversations about upcoming pubertal changes should begin before the changes become confusing or embarrassing. Dr. Rajiv suggests that families start these discussions calmly and scientifically around the pre-adolescent years.
How much screen time is too much for a teenager?
Short answer: The effect of screens is better judged by what they are displacing than by one universal number alone.
Is the teenager sleeping adequately? Exercising? Attending school and completing work? Eating with the family? Maintaining offline friendships? Is device use causing repeated conflict or continuing late into the night?
Screen rules are difficult to enforce when adults in the home model constant device use. Family routines often work better than rules aimed only at the teenager.
Where screen use is associated with major sleep disruption, declining function, severe conflict, mood concerns or compulsive behaviour, the issue deserves a broader assessment.
Why is adolescent obesity becoming common?
Short answer: Modern routines make excess calorie intake easy and movement optional. Food environment, screens, sleep and family habits can all contribute.
Dr. Rajiv’s interest in childhood obesity goes back to his postgraduate research on obesity, risk factors and hypertension in school-going children.
The conversation should focus on health rather than shame. Repeated comments about appearance can damage the relationship without producing sustainable behaviour change.
Useful changes are usually household changes: what food is routinely available, how often meals come from outside, how much the family moves, sleep timing and how screens fit into daily life.
Screens, Food and the Modern Teenager
Adolescent pediatrics is changing. Screens are everywhere. Food arrives at the door in minutes. Physical activity has decreased for many children. Sleep patterns have changed. Parents themselves are struggling with many of the same habits.
So telling a teenager simply to ‘use the phone less’ is not enough.
Families need conversations around routines, physical activity, food, sleep, puberty and behaviour. And perhaps most importantly, adults need to recognise that children learn a great deal from what they see us doing.
Keep routine care available to the teenager
Offer regular health visits even when no acute illness is present. They create space to review growth, blood pressure, sleep, menstrual or sexual health, mood, substance exposure, vaccination and safety, including a private conversation in which the adolescent can raise concerns directly.
Immediate help is needed for suicidal thoughts, self-harm, overdose, severe eating restriction with weakness or fainting, assault, exploitation or any situation in which a young person is not safe. Stay with the teenager and use local emergency services when danger is immediate.
