Diabetes in Children and Teenagers in Bangladesh: What Parents Need to Know

Diabetes Is Not Just for Adults

Many Bangladeshi parents and even some doctors associate diabetes with middle-aged, overweight people. But Type 1 diabetes can strike a 2-year-old. And as Bangladesh's youth become more sedentary and eat more processed food, Type 2 diabetes in teenagers is becoming a genuine concern.

Type 1 vs Type 2 Diabetes in Young People

Type 1 Diabetes

• The immune system destroys insulin-producing cells in the pancreas
• Not related to diet or lifestyle — it is an autoimmune disease
• Requires insulin injections for life
• Can appear at any age, including infancy — peak onset is 10–14 years
• Becomes life-threatening within days if not diagnosed (diabetic ketoacidosis)

Type 2 Diabetes in Teenagers

• Linked to obesity, physical inactivity, and poor diet
• The body makes insulin but cells resist its effect
• Previously rare in young people — now increasing globally and in Bangladesh
• Often manageable with lifestyle changes in early stages, but may require medication

Warning Signs in Children — Act Immediately

The classic "4 Ts" of Type 1 diabetes in children:

• Toilet: Urinating much more frequently than usual, including bedwetting in a previously dry child
• Thirsty: Drinking large amounts of water, impossible to quench
• Tired: Unusual, persistent fatigue even after rest
• Thinner: Unexplained weight loss despite eating normally or more than usual

Additional signs:

• Blurred vision
• Fruity-smelling breath (a sign of diabetic ketoacidosis — EMERGENCY)
• Abdominal pain, vomiting
• Breathing that is deep and rapid (Kussmaul breathing — EMERGENCY)

If a child has fruity breath, vomiting, rapid breathing and is drowsy — go to hospital immediately. This is life-threatening.

Diagnosis

A random blood glucose test above 11.1 mmol/L, or fasting glucose above 7.0 mmol/L, with symptoms, confirms diabetes.

Children with suspected Type 1 should be referred to a hospital immediately — they may need insulin within hours.

Managing Diabetes in a Child

Type 1:

• Insulin injections 3–5 times daily (or insulin pump)
• Blood glucose monitoring 4–8 times daily
• Carbohydrate counting at every meal
• The family must be trained — parents, grandparents, teachers and the school nurse all need to understand insulin and hypoglycaemia (low blood sugar) management

Type 2 in teenagers:

• Weight loss through diet and exercise is the first treatment
• Reduce refined carbohydrates: white rice, maida, sugar, soft drinks, chips
• Increase physical activity to 60 minutes daily
• Regular blood glucose and HbA1c monitoring

The School and Social Challenge

A child with diabetes faces challenges that adults do not:

• Missing meals due to school schedules
• Social pressure around food at weddings and family events
• Hypoglycaemic episodes during exams or sports
• Fear of injections in front of peers

Schools in Bangladesh generally have limited awareness of diabetes management. Parents should inform the school and class teacher, and ensure the child always carries glucose tablets or juice for hypoglycaemia emergencies.

Prevention of Type 2 Diabetes in Teenagers

• Limit screen time to 2 hours daily for children
• Encourage outdoor play and sports — 60 minutes of physical activity daily
• Replace sugary drinks (cola, fruit juice, milkshake) with water or plain milk
• Reduce ultra-processed snacks — chips, biscuits, instant noodles
• Annual blood glucose testing for overweight teenagers with a family history of diabetes
