• Type 1 diabetes results from immune attack on insulin cells.
• Early detection prevents life-threatening complications.
• Symptoms include frequent urination, thirst, weight loss, fatigue

Type 1 diabetes is a chronic autoimmune condition that results from an abnormal reaction of the body’s immune system. This reaction causes the body’s immune system to attack and damage cells that produce insulin.

This condition is also known as juvenile-onset or insulin-dependent diabetes. This condition is not related to lifestyle and may occur suddenly. This condition often occurs among young adults and children.

However, it may occur at any age. Insulin plays an essential role in controlling blood glucose levels and this is because insulin allows glucose to enter cells and produce energy. When insulin production stops or becomes inadequate, glucose levels increase. This increase causes many symptoms.

Dr Ram Sharma, Consultant Endocrinologist, Felix Healthcare, tells Moneycontrol that it is critical to detect type 1 diabetes as early as possible, since any delay can lead to complications such as diabetic ketoacidosis, which may be life-threatening.

What is Type 1 Diabetes

Type 1 diabetes happens when the body's insulin-producing centres in the pancreas are damaged, resulting in the production of little or no insulin in the body. As a result, the body cannot use glucose as an energy source, causing an increase in the level of glucose in the blood, as well as an energy deficiency in the body.

Symptoms of Type 1 Diabetes

Frequent urination (Polyuria)

The first noticeable symptom of Type 1 diabetes is the increased frequency of urination. Increased glucose in the blood forces the kidneys to work harder, causing an increased rate of urination.

Excessive thirst (polydipsia)

When the body loses more fluids due to excessive urination, it can cause dehydration, leading to thirst. You drink more water, but still feel as if you haven't had enough.

Unexplained weight loss

While one may eat as usual, if not more than usual, one may lose weight. This occurs because the body begins to metabolise fat and muscle to obtain energy due to the absence of insulin.

Increased hunger (Polyphagia)

Cells that lack the necessary glucose send signals to the brain to increase the intake of food. Consequently, the increased intake of food does not yield the desired energy due to the improper utilization of the ingested glucose.

Fatigue and weakness

Cells lack the necessary energy due to the lack of sufficient glucose in the bloodstream. Consequently, the lack of energy leads to weakness and difficulty in concentrating.

Blurred vision

An increase in the level of glucose in the bloodstream leads to the accumulation of fluids in the eye, which affects the eye’s ability to provide the desired vision.

Slow healing and frequent infections

It takes longer to heal from cuts or infections due to the high level of glucose in the bloodstream. Consequently, the high level of glucose weakens the immune system.

Nausea and vomiting

In the later stages of the development of the symptoms of type 1 diabetes, nausea and vomiting are likely to occur.

FAQs on Type 1 Diabetes

What is Type 1 diabetes?

Type 1 diabetes is a chronic autoimmune condition where the immune system attacks and damages insulin-producing cells in the pancreas, resulting in little or no insulin production.

Who is affected by Type 1 diabetes?

Type 1 diabetes commonly occurs in young adults and children but can develop at any age. It is not related to lifestyle factors.

What are the common symptoms of Type 1 diabetes?

Symptoms include frequent urination, excessive thirst, unexplained weight loss, increased hunger, fatigue, weakness, blurred vision, slow healing of wounds, and frequent infections.

Why is early detection of Type 1 diabetes important?

Early detection is crucial as it helps prevent complications like diabetic ketoacidosis, which can be life-threatening.

How does Type 1 diabetes affect insulin and glucose levels?

Without sufficient insulin, glucose cannot enter cells to produce energy. This leads to high blood glucose levels, causing various symptoms and energy deficiency in the body.
