OverviewOverview

Type 1 diabetes is a chronic condition in which the pancreas produces little or no insulin. Insulin is a hormone needed to allow sugar (glucose) to enter cells to produce energy. Unlike type 2 diabetes, type 1 diabetes is generally diagnosed in children and young adults, hence referred to as juvenile diabetes.

In type 1 diabetes, the body’s immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. This leaves the body unable to produce insulin and regulate blood sugar levels, leading to a range of potential health complications if not properly managed.

Risk Factors

Several risk factors can increase the likelihood of developing type 1 diabetes. These include:

Family history: Having a parent or sibling with type 1 diabetes increases the risk.
Genetics: Certain genes predispose individuals to the disease.
Geography: The incidence of type 1 diabetes increases as you travel away from the equator.
Age: Although type 1 diabetes can appear at any age, it typically manifests in children, teens, or young adults.

Causes

While the exact cause of type 1 diabetes is unknown, researchers believe that it is a combination of genetic and environmental factors. The autoimmune response is thought to be triggered by unknown environmental factors, possibly viruses.

As the immune system attacks and destroys the beta cells in the pancreas that produce insulin, this insulin deficiency prevents the body from regulating blood glucose levels, resulting in diabetes.

Signs and Symptoms

The symptoms of type 1 diabetes can develop rapidly, especially in children. Common signs and symptoms include:

Increased thirst and frequent urination
Extreme hunger
Unintended weight loss
Irritability and mood changes
Fatigue and weakness
Blurred vision
Fruity-smelling breath

Diagnosis and Tests

Diagnosing type 1 diabetes typically involves several blood tests to measure blood sugar levels. These tests may include:

Screening: The American Diabetes Association recommends Type 1 diabetes screening for all first-degree relatives of people with type 1 diabetes.
Fasting blood sugar test: Measures blood glucose after fasting for at least 8 hours.
Random blood sugar test: Measures blood glucose levels at a random time.
HbA1c test: Provides an average blood sugar level over the past 2 to 3 months.

Additionally, other autoimmune markers or the presence of specific antibodies may be tested to confirm an autoimmune origin for the disease.

Staging

With advances in pathophysiology and advent of therapies to prevent progression, the community has developed a well-defined staging criterion for type 1 diabetes.

Stage 1: The start of type 1 diabetes. Individuals test positive for 2 or more diabetes-related autoantibodies. The immune system has already begun attacking the insulin-producing beta cells, although there are no symptoms and blood sugar remains normal.
Stage 2: Like stage 1, includes individuals who have two or more diabetes-related autoantibodies, but now, blood sugar levels have become abnormal due to increasing loss of beta cells. There are still no symptoms.
Stage 3: This is when clinical diagnosis typically takes place. By this time, there is significant beta cell loss and individuals generally show common symptoms of type 1 diabetes, which include frequent urination, excessive thirst, weight loss, and fatigue.

Treatments

While there is no cure for type 1 diabetes, it can be managed through a combination of insulin therapy, lifestyle changes, and continuous monitoring of blood glucose levels. Treatment options include:

Insulin therapy: Involves daily injections or an insulin pump to manage blood sugar levels.
Diet and nutrition: Following a balanced diet to help maintain stable blood sugar levels.
Physical activity: Regular exercise helps improve insulin sensitivity.
Blood sugar monitoring: Regularly checking blood glucose levels to ensure they stay within a target range.
Teplizumab: The first FDA approved therapy for delaying progression to stage 3 type 1 diabetes among those aged 8 years and older with stage 2 type 1 diabetes

Living with type 1 diabetes can be challenging, but with the right information and support, individuals can manage their condition effectively. Here are some tips and resources to consider:
