At first glance, diabetes may seem like a single disease with different faces, but modern science reveals a more complex picture. There is a special type known as Latent Autoimmune Diabetes in Adults (LADA), a unique condition combining features of both type 1 and type 2 diabetes, usually affecting adults over the age of thirty.

According to the Vinmec website, this disease occurs when the immune system mistakenly attacks the cells responsible for producing insulin in the pancreas, leading to a gradual decline in its ability to secrete this vital hormone.

LADA is not as rare as commonly believed, but it is often undiagnosed in a timely manner.

The combination of accurate diagnosis, early treatment, and lifestyle changes can completely alter the disease’s course. With ongoing advances in immunology and gene therapy, a day may come when medicine can rebalance the immune system to stop attacking its own cells. Until then, conscious management and personal responsibility remain the safest way to maintain health and prevent complications.

LADA is sometimes called “type 1.5 diabetes” because it lies between the two most common forms of diabetes.

While the immune system destroys pancreatic cells rapidly in type 1 diabetes, in LADA this happens slowly, initially making the patient appear to have type 2 diabetes. The body may respond in early stages to oral medications and dietary regulation, but over time pancreatic cells lose their ability to produce insulin, and insulin therapy becomes inevitable.

The disease starts silently. Initially, the pancreas can produce limited amounts of insulin, allowing the patient to control blood sugar levels through healthy eating, exercise, and medication. However, the immune attack continues, and over the years the insulin-producing beta cells gradually decrease until the body cannot meet its needs.

Studies show that toxins and chronic inflammation may contribute to damage of these cells, alongside genetic factors that make some individuals more susceptible than others.

Patients with LADA are often misdiagnosed as having type 2 diabetes due to symptom similarity and slow disease progression.

However, subtle differences can be detected by doctors through special blood tests including:

• Testing for antibodies attacking pancreatic cells.
• Measuring C-peptide levels reflecting the amount of insulin the body produces.

If a patient notices unexplained weight loss, poor response to usual medication, or sudden deterioration, these are indicators warranting thorough testing for possible LADA. Early diagnosis plays a pivotal role in slowing pancreatic cell destruction and preserving their function as long as possible.

Treatment of LADA, as with all diabetes types, aims to maintain continuous blood sugar balance and prevent chronic complications.

In early stages, oral medications commonly used in type 2 diabetes can help regulate sugar, especially with a balanced diet aimed at weight loss and improving insulin sensitivity.

But as beta cells continue to decline, these medications lose effectiveness and external insulin becomes the primary treatment.

Multiple studies indicate that early initiation of insulin therapy immediately after diagnosis helps preserve insulin-producing cells, improves metabolic control, and reduces autoimmune inflammation.

Patients usually require insulin injections within five years of disease onset, with doses varying according to individual needs and lifestyle.

Treatment is not based on medication alone. Lifestyle is the cornerstone of controlling LADA, including:

• Adhering to a balanced diet low in saturated sugars and rich in fiber and proteins.
• Regular exercise to improve insulin sensitivity.
• Periodic blood sugar monitoring to ensure precise treatment adjustment.
• Avoiding smoking and reducing psychological stress, as chronic stress raises sugar levels and weakens treatment response.

Leaving the disease unmanaged leads to continuous high blood sugar, causing a series of complications including:

• Chronic kidney diseases.
• Retinopathy and vision impairment.
• Heart and vascular diseases.
• Nerve damage and poor wound healing.

LADA patients also have an increased likelihood of thyroid disorders due to shared autoimmune dysfunction, requiring regular endocrine follow-up.

However, reports indicate that those who adhere to treatment and monitor their health can enjoy a normal lifespan just like healthy individuals.

There is no known way to prevent LADA due to its genetic autoimmune nature. However, early detection, prompt treatment, and commitment to a healthy lifestyle are all factors capable of slowing pancreatic deterioration and delaying full insulin dependence. Awareness among patients and doctors alike is the most important weapon in combating this type of diabetes.
