As a result of obesity it is possible that for the first time in history our children may have a shorter lifespan than their parents.

What are the complications of childhood obesity?

Obesity in childhood may result in serious medical problems in childhood such as:

• type 2 diabetes
• high blood pressure and elevated blood cholesterol
• metabolic syndrome: a number of conditions that are all associated with high blood insulin levels including type 2 diabetes and high blood pressure
• liver disease
• bone and joint problems
• respiratory problems such as asthma
• sleep disorders such as difficulty breathing while asleep (sleep apnea)
• earlier than normal puberty or menstruation
• eating disorders such as anorexia or bulimia
• skin infections due to moisture from sweat being trapped in skin folds
• fatigue

Overweight or obesity in childhood can also result in serious psychological difficulties.

Overweight or obese children:

• are more likely to be teased and bullied
• are more likely to bully others
• may have poor self-esteem and may feel socially isolated
• may be at increased risk for depression
• may have poorer social skills
• may have high stress and anxiety
• may have behaviour and/or learning problems as a result of psychological difficulties related to childhood obesity

Unfortunately most obese children and youth do not outgrow their weight problem. In fact, most people continue to gain weight as they age.

Obesity in adulthood leads to:

• high blood pressure
• strokes
• cancer
• heart disease
• liver disease
• type 2 diabetes
• dementia

An adult who is obese at age 40 years can expect to die 7 years earlier than someone who was of normal weight at the same age. The loss of years is the same as if that person had been a smoker. It is essential that families do all they can to prevent obesity in children and to have it treated it should it occur.
