Understanding Type 1 Diabetes Mellitus
What is Type 1 Diabetes?
Type 1 diabetes is an autoimmune condition where the body’s immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas.
Without these cells, the body cannot produce insulin, the hormone that enables glucose to enter cells and provide energy.
In a healthy individual, the pancreas produces insulin continuously in response to blood glucose levels.
This process is so precise that it maintains blood glucose within the narrow range of 4-6.5 mmol/L.
However, in someone with type 1 diabetes, this automatic regulation is lost, making blood glucose management a constant challenge.

How Type 1 Diabetes Differs from Other Types
Type 1 diabetes is fundamentally different from other forms of diabetes:
Type 1 Diabetes: An autoimmune condition where the body cannot produce insulin. It typically develops quickly, usually in childhood or young adulthood, and requires insulin therapy for life.
Type 2 Diabetes: A metabolic disorder where the body becomes resistant to insulin or doesn’t produce enough insulin. It’s often associated with lifestyle factors like obesity and physical inactivity.
Gestational Diabetes: A temporary form of diabetes that occurs during pregnancy, typically resolving after childbirth.

Causes and Risk Factors
The exact cause of type 1 diabetes remains unknown, but several factors contribute to its development:
Having certain genes increases the risk of developing type 1 diabetes. If a parent or sibling has type 1 diabetes, the risk is slightly higher.
Autoimmune Response: The immune system mistakenly identifies beta cells as foreign invaders and attacks them.
Environmental Triggers: Certain viruses or environmental factors may trigger the autoimmune response in genetically susceptible individuals.
Geography: Interestingly, the incidence of type 1 diabetes varies by location, suggesting environmental factors may play a role.

Signs and Symptoms of Type 1 Diabetes
The onset of type 1 diabetes is often rapid, and symptoms can develop over days or weeks. Key symptoms include:
- Excessive thirst and frequent urination: The body tries to eliminate excess glucose through urine, leading to dehydration and increased thirst.
- Extreme hunger: Despite eating, cells are starved of glucose, triggering hunger signals.
- Unexplained weight loss: Without insulin, the body burns fat and muscle for energy, resulting in weight loss despite normal or increased food intake.
- Fatigue: Cells cannot access glucose for energy, leading to tiredness.
- Blurred vision: High blood glucose can affect the fluid in the eye lenses.
- Slow-healing sores or frequent infections: Elevated blood glucose impairs the body’s natural healing processes.
A serious complication called diabetic ketoacidosis (DKA) may also develop, causing:
- Rapid breathing
- Nausea or vomiting
- Abdominal pain
- Fruity-smelling breath

Diagnosing Type 1 Diabetes in Singapore
Singapore’s healthcare system offers various tests to diagnose type 1 diabetes accurately:
Blood Glucose Tests
Random Blood Glucose Test: A blood sample taken at any time showing glucose levels of 11.1 mmol/L or higher suggests diabetes.
Fasting Blood Glucose Test: After an overnight fast, a reading of 7.0 mmol/L or higher on two separate occasions confirms diabetes.
Oral Glucose Tolerance Test (OGTT): After consuming a sugary solution, blood glucose levels are measured periodically. A reading of 11.1 mmol/L or higher after two hours indicates diabetes.
Additional Diagnostic Tests
Glycated Hemoglobin (HbA1c) Test: Shows average blood glucose levels over the past 2-3 months.
C-Peptide Test: Measures the level of C-peptide, which is produced alongside insulin. Low levels suggest type 1 diabetes.
Autoantibody Tests: Identifies antibodies commonly present in type 1 diabetes, confirming an autoimmune process.

Type 1 Diabetes Treatment Approaches in Singapore
Treatment for type 1 diabetes in Singapore focuses on replacing insulin, monitoring blood glucose levels, and preventing complications through a combination of approaches.
Insulin Therapy
Since the body cannot produce insulin, replacement therapy is essential. In Singapore, patients typically follow a basal-bolus insulin regimen:
Basal (Background) Insulin: Provides a constant supply of insulin throughout the day and night, mimicking the pancreas’s baseline insulin production.
Bolus (Mealtime) Insulin: Quick-acting insulin taken before meals to handle the rise in blood glucose after eating.
The specific insulin types available in Singapore include:
Long-acting insulin analogs (for basal insulin): Last up to 24 hours with a steady effect
Rapid-acting insulin analogs (for bolus insulin): Begin working within 15 minutes and last 3-4 hours
Regular human insulin: Takes longer to start working but costs less than analogs
