What is Diabetes?
Diabetes is a metabolic disorder that results in high blood glucose levels, due to the body's inability to produce enough insulin or effectively utilise the insulin it produces.
Glucose is the energy source of our body, which is broken down from the food we eat. A diabetic person's body doesn’t make enough insulin or can’t use it properly. It leads to high glucose buildup in the blood. When the high glucose level persists over time, it leads to major health complications—affecting the kidneys, heart, eyes, nerves, and more.
Here are the numerous types:
1
Type I Diabetes: An autoimmune condition where the body attacks insulin-producing cells.
2
Type II Diabetes: Linked to insulin resistance, often influenced by lifestyle.
3
Maturity Onset Diabetes of the Young (MODY): A rare, inherited form of diabetes that appears in adolescents or young adults due to a single gene mutation.
4
Gestational Diabetes: Occurs during pregnancy, usually temporary.
5
Neonatal Diabetes Mellitus: It is a rare form of diabetes diagnosed in infants under six months. Genetic mutations usually cause it.
6
Secondary Diabetes: Diabetes arising from another medical condition or as a side effect of certain medications.
All diabetes types involve blood sugar dysregulation, but causes and treatments vary.

What Is Type I Diabetes?
Type I Diabetes, or T1D, is a long-term condition. It occurs when the body stops making insulin, a hormone that controls blood sugar. For reasons still unknown, the immune system begins to attack the insulin-producing cells in the pancreas.
Without insulin:
Sugar builds up in the blood.
Energy doesn’t reach the muscles and organs.
The body starts breaking down fat as a backup.
This form is quite different from Type II Diabetes, which often relates to lifestyle. Type I usually appears in children or teenagers, although adults can also develop it.
What Are the Types of Type I Diabetes?
There are different kinds of Type I Diabetes. Not every person with Type I Diabetes fits the same box, with doctors deciding the treatments accordingly. Understanding the types can help patients and healthcare providers take a more personalised approach.
The two primary types of Type I Diabetes are:
1
Immune-mediated Diabetes: This is the most common form, accounting for the majority of Type 1 Diabetes cases. In this type, the body’s immune system mistakenly attacks and damages insulin-producing beta cells in the pancreas. As a result, the pancreas can no longer produce enough insulin to regulate blood sugar levels. This process typically occurs in childhood or adolescence.
2
Idiopathic Type I Diabetes: This variant is rarer and less understood. While it still involves insulin deficiency, there’s no clear evidence of the immune system attacking the pancreas. People with idiopathic Type I may show some signs of diabetes, but without the typical immune response seen in the immune-mediated form. This makes it harder to diagnose and manage effectively. It can occur at any age and often presents with mild symptoms initially, leading to a delay in diagnosis.
Additionally, there's a condition called Latent Autoimmune Diabetes in Adults (LADA). LADA or 1.5 Diabetes often mimics Type II Diabetes at first, which can confuse both patients and doctors. However, over time, it gradually turns into Type I Diabetes.

How Is Type I Diabetes Diagnosed?
Type I is most commonly diagnosed in children, teens, or young adults. However, adults can also be affected. Doctors usually recommend tests based on your symptoms.
It include:
1
Blood Sugar Tests: The fasting and non-fasting bloodwork is a common test used to check glucose levels:
Random Blood Sugar Test: It measures blood sugar at any time of the day, regardless of when you last ate.
Fasting Blood Sugar Test: A maximum fasting of eight hours is required before the test. High sugar levels may indicate diabetes.
2
HbA1c Test: It gives an average of the sugar levels over the past 2–3 months. It helps determine how well your diabetes is being managed over time.
3
C-Peptide Test: This test measures the amount of insulin the pancreas is producing. It helps doctors determine whether the pancreas is still producing insulin or has become entirely dependent on insulin injections.
4
Autoantibody Tests: These tests detect antibodies in the blood, indicating that the immune system is attacking the pancreas and its insulin-producing cells.
Early diagnosis of diabetes is critical as it helps prevent complications like diabetic ketoacidosis (DKA), a life-threatening condition caused by extremely high blood sugar levels

What are the Symptoms of Type I Diabetes?
Symptoms of Type I Diabetes often develop rapidly, over a few days or weeks, and tend to be quite noticeable.
Here’s what to watch for:
1
Constant Thirst: You might always feel thirsty, no matter how much water you drink.
2
Frequent Urination: This often becomes especially noticeable at night, as you may need to go to the bathroom more frequently.
3
Unexplained Weight Loss: You could lose weight even if you eat more than usual.
4
Extreme Fatigue: A constant tiredness throughout the day.
5
Blurred Vision: Eyesight may become blurry, making it hard to see clearly.
6
Dry Mouth & Itchy Skin: These can be signs of dehydration, a common symptom.
7
Bedwetting: This might be the first sign in children, especially if they had been previously toilet-trained.
8
Slow-Healing Wounds: Cuts or bruises take longer than usual to heal.
Note: If you experience a combination of these symptoms, do not ignore them and consult your doctor immediately.
Don’t wait for symptoms to worsen.

When to See a Doctor for Type I Diabetes?
If you or your child faces any of the following symptoms, see a doctor immediately:
1
Severe thirst and fatigue: Feeling chronically thirsty and unable to quench your thirst can be a symptom. Moreover, perennial fatigue, despite rest and hydration, could indicate high blood sugar levels.
2
Weight loss without reason: If you're losing weight rapidly without changing your diet or exercise habits, this could be a red flag that your body is not absorbing sugar properly due to a lack of insulin.
3
Confusion or drowsiness: These symptoms, especially when accompanied by a lack of focus, may indicate dangerously high blood sugar, which can lead to a medical emergency.
4
Nausea, vomiting, or stomach pain: It might signal Diabetic Ketoacidosis (DKA), a critical complication of diabetes in which the body starts breaking down fat too quickly, causing toxic acids to build up.
5
Fruity-smelling breath: When blood sugar levels are pretty high, the body produces ketones, which can cause a distinct fruity or acetone-like smell in the breath.
If any of these symptoms appear, do not delay seeking medical help. Timely diagnosis and insulin dosage for diabetes can help manage the condition effectively.

What is the Current Scenario of Type I Diabetes in India?
According to data published by the Indian Council of Medical Research (ICMR), India has nearly 97,000 children living with Type I Diabetes. And the number is rising alarmingly. Early detection and care still face challenges, especially in smaller towns.
Facts to note:
Insulin is not readily available in remote areas.
Many families are unaware of the condition.
Regular checkups and HbA1c tests are often skipped.
Awareness about diabetic ketoacidosis (DKA) is low.
India needs to focus more on this invisible crisis. It is high time that schools, colleges, and local clinics participate in the diabetes awareness drives.
Don't let rising costs delay diabetes treatment.

What Are the Complications of Type I Diabetes?
If not managed effectively, Type I Diabetes can lead to long-term complications, affect various organs and systems in the body. Persistently high blood sugar levels may gradually damage nerves, blood vessels, and critical organs. These complications may not appear immediately, but they can affect quality of life if left unchecked.
Common complications include:
1
Diabetic Ketoacidosis (DKA): A serious condition resulting from dangerously high blood sugar and low insulin.
2
Nerve Damage (Neuropathy): Tingling, numbness, or pain—often in hands and feet—due to damaged nerves.
3
Kidney Disease (Nephropathy): High sugar overworks the kidneys, possibly leading to kidney failure.
4
Eye Damage (Retinopathy): The blood vessels in the retina may become damaged, affecting vision or even causing blindness.
5
Heart Disease and Stroke: There is an increased threat of heart attacks and strokes in diabetes.
6
Foot Problems: Poor blood flow and nerve damage can cause slow-healing wounds, ulcers, or infections.
7
Skin and Mouth Infections: Dry skin, fungal infections, and gum disease can become more common.
