You are not alone

Obesity is a disease and there are over 175 million children and teenagers living with it around the world­. Despite this, a history of misunderstanding across society has caused many teenagers to not understand their own condition, the causes and how to get support, which can feel isolating.

More to obesity than we realise?

It is important for teenagers who live with obesity to understand there may be more behind their weight than just their relationship with food and exercise. Did you know that between 40-70% of all obesity is related to genetics? This means that many teenagers living with obesity have inherited a higher chance of developing this disease during their lifetime.

How can genes affect someone’s weight? Genes can influence:

  • How much food is consumed in a sitting
  • How someone responds to the sensation of fullness
  • How much enjoyment is received from certain types of food
  • How much energy is needed to run a body’s basic functions
  • How and where excess calories are stored as fat in a body

We now know that these things might have less to do with our personalities and lifestyle choices and more to do with our genes.

If you would like to know more about how genetics contribute to your weight, you can read our article ‘Is obesity genetic?’ here.

Additionally, if you would like to find out about how your hormones affect your weight, you can read our articles ‘How hormones steer our appetite and eating behaviour’ here, or download a short guide to hormones and weight.

Obesity and your health

Sometime there are other challenges that teenagers may face because of their condition. These can include difficulties with mental health, troubles with joints and bones, plus shortness of breath.

If you are struggling with your weight, you can talk to your healthcare professional or doctor about it.

It is the responsibility of a doctor to help teenagers to manage their health and to recommend the best treatment options. These may include a variety of methods, from lifestyle changes through to medical treatment. Finding a solution to help manage obesity is not simple and may take multiple visits to a doctor to work out the right way to proceed.

Teenagers may feel nervous about speaking to a doctor. Some may benefit from discussing their feelings or concerns with a parent or caregiver first, who also may have experienced obesity themselves. Some teenagers may find that their friends and family can provide helpful support when taking the first steps towards managing their own weight.

You can get support

If you are ready to reach out to a doctor for support, you can find your local obesity care provider here.

Below are some simple steps to help you talk to your doctor about your weight:
Step 1

  • Use the HCP locator (in the link above) or reach out to your local doctor to book an appointment – you may want to ask your parent or guardian to do this for you

Step 2

  • Your doctor may ask what your day-to-day routine looks like, so a couple of weeks before your appointment make a note of your day, including any activities you are involved in, and what you eat
  • This will help you explain to your doctor about your lifestyle and will also help your doctor recommend the best approach for you
  • The conversation with your doctor should be balanced and in no way imply any blame

Step 3

  • Make sure you feel comfortable discussing your weight with your doctor. In some countries, you might have a short appointment time so don’t be disheartened if you don’t get to talk about everything immediately
  • Try to identify the key priorities or main points that you want to discuss and take a note of them with you, so you don’t forget once in the clinic

Step 4

  • Persevere! If you leave the appointment feeling dissatisfied, do not give up. There will be other doctors and obesity care providers ready to help you. If you need additional support, there are many patient organisations who can provide this, several have been listed below
