Type 1 and Type 2 Diabetes Mellitus (Children)

2024/05/31
What Is Diabetes Mellitus

Diabetes Mellitus is a chronic condition characterised by elevated blood sugar levels. It occurs in two forms: Type 1 and Type 2. Insulin, a hormone produced by the pancreas, helps glucose from the bloodstream enter body cells to be used for energy.

In Type 1 Diabetes Mellitus, the body produces insufficient insulin. In Type 2 Diabetes Mellitus, the does not utilise the insulin effectively, known as insulin resistance. As a result, glucose remains in the bloodstream.

While Type 1 Diabetes Mellitus is more common among children in Singapore1, the incidence of Type 2 Diabetes Mellitus is rising, partly due to a increased childhood obesity1.

Causes of Diabetes Mellitus

Type 1 Diabetes Mellitus

This autoimmune condition results in the destruction of pancreatic beta cells by the body's immune system. It can occur at any age but is more common in children and young adults. Its exact cause is unknown but likely involves genetic and environmental factors, including viruses.

Type 2 Diabetes Mellitus

Often linked to obesity, Type 2 Diabetes Mellitus can also be caused by certain medications. Affected children frequently have family members with the same condition.

Signs And Symptoms Of Diabetes Mellitus

​Symptoms of Type 1 Diabetes Mellitus

  • Excessive thirst or hunger
  • Frequent unration, including at night
  • Unexplained weight loss
  • Fatigue
  • Abdominal pain
  • Dry mouth
  • Blurred vision
  • Bed-wetting

Symptoms of Type 2 Diabetes Mellitus

  • Excessive thirst or hunger
  • Frequent unration, including at night
  • Darkened skin on the back of the neck or armpits (Acanthosis Nigricans)
  • Symptoms may be absent or develop gradually, often discovered during health screenings
Diagnosis And Treatment Options For Diabetes Mellitus

Type 1 Diabetes Mellitus

  • Treatment involves insulin injections. Various delivery methods and insulin types (ultra-short-acting, short-acting, intermediate-acting, long-acting) are available.
  • The insulin regimen is tailored to the child's lifestyle and dietary habits.

Type 2 Diabetes Mellitus

  • Diagnosed using an Oral Glucose Tolerance Test (OGTT).
  • Treatment includes diet control, oral medications, and maintaining a healthy lifestyle. Some cases may require insulin injections.
Tips For Taking Care Of Children with Diabetes Mellitus

Proper management allows children with Diabetes Mellitus to lead healthy, active lives. Support from family, friends, schools and healthcare professionals is crucial for motivation and effective diabetes control.

Our Child and Adolescent Diabetes Support Group offers an annual camp, motivational courses and parent support groups. For more information, please click here.

Research On Diabetes Mellitus

Continued clinical research is essential for advancing paediatric healthcare. Our doctors are committed to contributing to the future of child health and medicine through both clinical practice and research.
