Type 1 Diabetes: Symptoms and Causes

Type 1 diabetes is a serious medical condition that affects thousands of people worldwide. In this disorder, the immune system incorrectly identifies and destroys the beta cells in the pancreas, which produce insulin. Unlike type 2 diabetes, which is commonly linked to lifestyle factors, type 1 diabetes develops independently of these influences. This results in little to no insulin production, a hormone essential for regulating blood sugar levels.

In this article, we will explore the causes of type 1 diabetes, symptoms, and treatment options, helping you better understand this condition.

What is Type 1 Diabetes, and How is it Different from Type 2 Diabetes?

Type 1 diabetes develops when your body’s immune system destroys the beta cells in the pancreas. Without enough insulin, glucose from food cannot enter the body’s cells to be used as energy, causing glucose levels to build up in the blood.

High blood sugar, or hyperglycaemia, leads to various health problems if left untreated. People with type 1 diabetes need daily insulin administration to manage their blood sugar levels and avoid complications.

On the other hand, Type 2 diabetes develops when the body becomes resistant to insulin or does not produce enough of it. Lifestyle factors, such as diet, physical activity, and body weight, play a significant role in its onset. Many people with Type 2 diabetes can manage the condition through healthy lifestyle changes, oral medications, and sometimes insulin therapy.

Causes of Type 1 Diabetes

The exact type 1 diabetes causes are not yet fully understood, but research points to a combination of genetic and environmental factors:

• Autoimmune Reaction: As mentioned before, Type 1 diabetes occurs when the immune system attacks beta cells in the pancreas. A virus or other unknown environmental factors may trigger this autoimmune response.
• Genetics: Type 1 diabetes can run in families, although not everyone with a family history will develop the condition.
• Environmental Triggers: Certain viruses or dietary factors during early childhood might contribute, but this link requires more research.

Recognising the Symptoms of Type 1 Diabetes

Understanding the type 1 diabetes symptoms and signs is crucial for early diagnosis and treatment. These symptoms often develop quickly over days or weeks:

• High blood sugar causes increased thirst and hunger. The body tries to remove excess glucose through urine, leading to dehydration and increased thirst.
• Frequent urination because of excess glucose in the bloodstream causes the kidneys to work harder to filter and absorb it, leading to more frequent urination.
• Weight loss despite eating more. That’s because the body cannot absorb glucose properly, leading it to break down fat and muscle for energy.
• Cells lack energy due to insufficient glucose uptake, causing tiredness.
• High blood sugar affects fluid levels in the eyes, impacting vision.

Complications Associated with Type 1 Diabetes

When blood sugar levels remain uncontrolled, several complications can arise:

• Diabetic Kidney Disease: It is also known as diabetic nephropathy. It can lead to kidney failure if untreated.
• Diabetic Neuropathy: Nerve damage that causes pain, numbness, or weakness, often starting in the feet.
• Diabetic Retinopathy: Eye damage that can lead to vision loss.
• Cardiovascular Disease: People with diabetes have a higher risk of heart attack and stroke.
• Hypoglycaemia: This is low blood sugar, which can occur if too much insulin is taken or if meals are missed. Symptoms include confusion, sweating, dizziness, and, in severe cases, seizures or coma.
• Skin and dental problems: Diabetes can cause infections, gum disease, and slow wound healing.
• Mental Health Issues: Managing diabetes can be stressful and lead to depression or anxiety.

Timely and proper management can reduce the risk of these complications.

Diagnosing Type 1 Diabetes

Diagnosis typically involves blood tests to measure glucose levels. Common tests include:

• Random Plasma Glucose Test: It measures blood sugar at any time.
• Haemoglobin A1C Test: This test shows average blood glucose over the past 2-3 months.
• Autoantibody Tests: These check for immune system markers typical of type 1 diabetes.

A healthcare professional, especially an endocrinologist or diabetologist, can confirm the diagnosis and recommend treatment.

Treatment for Type 1 Diabetes

There is no cure for type 1 diabetes, but it can be managed effectively with the right treatment. The primary treatment involves:

• Insulin Therapy: To regulate blood sugar, people with type 1 diabetes need to take insulin through injections, insulin pens, or insulin pumps.
• Regular Blood Sugar Monitoring: Frequent testing helps adjust insulin doses and manage the condition.
• Diet and Lifestyle Changes: Eating a balanced diet, regular physical activity, and maintaining a healthy weight support blood sugar control.
• Additional Medications: In some cases, medications like pramlintide help manage blood sugar after meals.

Following the prescribed treatment reduces the risk of complications like diabetic kidney disease and hypoglycaemia.

Is Type 1 diabetes dangerous?

Yes, if not treated properly, Type 1 diabetes can be life-threatening. It can cause diabetic ketoacidosis (DKA) and long-term complications like heart disease, kidney damage, and nerve issues.

At what age does Type 1 diabetes usually develop?

Type 1 diabetes often starts in childhood or adolescence. However, it can develop at any age.

What foods should people with Type 1 diabetes avoid?

People with Type 1 diabetes should avoid or limit these food items:

• Sugary foods and drinks (cakes, sweets, soda)
• Refined grains (white bread, pasta, rice)
• Processed and fried foods
• High-fat foods with saturated or trans fats

What is the best way to manage Type 1 diabetes?

• Taking insulin daily
• Having a balanced diet
• Monitoring blood sugar every day
• Exercising and maintaining a healthy weight

Is Type 1 diabetes hereditary?

Yes, genetics plays a role. Having a family history of Type 1 diabetes increases your risk. However, environmental factors also contribute.
