What is Type 1 Diabetes?

  • Type 1 diabetes is the type of diabetes in which your body does not produce insulin because your immune system is attacking and destroying the insulin-producing cells in your pancreas.
  • It is an autoimmune condition. It is diagnosed with a random blood-sugar test or a glycated A1C test. 

What is Type 2 Diabetes?

  • In type 2 diabetes, the body does not respond to insulin like it should, also known as insulin resistance. This means the glucose cannot enter the cells of your body. Leading to an increase in blood sugar levels.
  • Prolonged exposure to increased blood sugar levels can even lead to reduced insulin production. And also lead to serious health complications. It is diagnosed with a random blood-sugar test or an HbA1C test

Difference Between Type 1 and Type 2 Diabetes

The main difference is that type 1 diabetes is a genetic condition and is also known as juvenile diabetes, as it affects children (4-7 years) and teenagers (10-14 years). Whereas type 2 diabetes is a lifestyle metabolic disorder that develops over time.  

What Causes Diabetes?

Aspect Type 1 Diabetes Type 2 Diabetes
Cause Autoimmune reaction leading to destruction of insulin-producing cells in the pancreas. Body becomes resistant to insulin or the pancreas doesn’t produce enough insulin.
Age of Onset Usually diagnosed in children and young adults, but it can occur at any age. Most commonly occurs in adults but is increasingly seen in children and teens.
Body Weight Often normal or underweight at the time of diagnosis. Often overweight or obese; however, it can also occur in individuals with normal weight.
Insulin Production Little to no insulin production. Insulin production is usually present but inadequate due to insulin resistance.
Symptoms Rapid onset of symptoms such as frequent urination, extreme thirst, and weight loss. Symptoms may be mild or absent initially; common symptoms include fatigue, blurred vision, and slow healing.
Treatment Insulin injections are necessary for survival, along with dietary management and exercise. Managed with lifestyle changes, oral medications, and sometimes insulin.

Causes of Type 1 Diabetes

It is a type of autoimmune disease. Most of the time, it is genetic or certain environmental elements. 

  1. In type 1 diabetes, the body’s immune system attacks the insulin-producing cells in the pancreas. 
  2. As a result, the body is no longer able to produce insulin. 
  3. Type 1 diabetes is often hereditary and is first seen in childhood and adolescence. It can also occur in adulthood over the age of 40.  

Causes of Type 2 Diabetes

In type 2 diabetes, your body usually becomes resistant to the insulin that is being produced or there is added insulin deficiency. 

  1. The pancreas produces insulin, but the body is not able to use it effectively.
  2. The risk factors for type 2 diabetes are age, family history, lifestyle, and obesity. 
  3. The good thing about type 2 diabetes is that with timely diagnosis, the right treatment, and positive lifestyle changes, it can be put into remission. 

Early Signs of Type 1 Diabetes and Type 2 Diabetes

Both type 1 and type 2 diabetes usually have the same kind of symptoms. Here are some of the most common signs and symptoms of type 1 and type 2 diabetes:

  1. Dry and itchy skin
  2. Sores, cuts or wounds take longer to heal
  3. Feeling excessively thirsty, more than earlier
  4. Frequent need to urinate
  5. Blurry vision or changes in vision
  6. Unexplained weight loss
  7. Excessive fatigue and tiredness
  8. Hunger levels vary
  9. Tingling sensation in limbs, especially feet 
  10. In some children, it can also lead to bedwetting

Treatment of Diabetes (Type 1 and Type 2)

Type 1 diabetes is a lifelong condition that requires careful management. Treatment typically includes lifestyle modifications, regular monitoring, and insulin therapy. Here’s how people with Type 1 diabetes can manage their condition:

1. Lifestyle Modifications

  • Eat better: Include more dal, chickpeas, and paneer for protein. Add lots of fiber with vegetables like okra (bhindi) and leafy greens (spinach or methi). Choose whole grains like brown rice or millet over white rice and rotis made from whole wheat.
  • Get moving: Take daily walks, practice yoga, or join a dance class. Even regular household chores can keep you active.
  • Manage stress and sleep well: Meditation and deep breathing exercises can help reduce stress. Try to stick to a regular sleep schedule.
  • Lose weight if needed: A bit of weight loss can make it easier for your body to use insulin. Simple changes like eating less fried food and sweets can help.
  • Check your sugar levels often: Use a glucometer to keep track of your blood sugar. This way, you know what foods and activities work best for you.

2. Monitoring

  • Blood Sugar Monitoring: Regular monitoring of blood sugar levels is crucial. This can be done using traditional blood glucose meters or continuous glucose monitoring systems. The frequency of monitoring will depend on the personalised treatment plan and level of blood sugar control.
  • Hemoglobin A1C Tests: This test provides an average blood sugar level over the past 2 to 3 months. It helps to understand how well the diabetes is being managed over time. The goal for most people with Type 1 diabetes is to have an A1C level of less than 7%.

Treatment options for Type 1 Diabetes: Insulin therapy

  • Insulin Therapy: All people with Type 1 diabetes require insulin to control their blood sugar levels. There are various types of insulin available (rapid-acting, long-acting, premixed), and the type and dosage depend on the individual’s needs.

Type 2 Diabetes Treatment

Some of the most common treatment for type 2 diabetes or management options include

  1. Lifestyle modification along with proper diet
  2. Oral medications as suggested by your healthcare provider 
  3. Insulin therapy when required

Risk Factors for Type 1 Diabetes

  1. Parent or sibling has type 1 diabetes. 
  2. More common in children and adolescents.
  3. Certain types of genes can affect the chances of type 1 diabetes. 
  4. Geographical areas that are farther from the equator have a higher prevalence of people with type 1 diabetes. 

Risk Factors for Type 2 Diabetes

  1. Slightly higher levels of blood sugar levels or prediabetes.
  2. Excessive fat around the belly area.
  3. Parent or sibling with type 2 diabetes.
  4. Have PCOS 
  5. Over the age of 45.
  6. Lead a sedentary lifestyle with no or less exercise. 
  7. Are overweight or obese? 
  8. History of gestational diabetes

How Does Diabetes Affect the Body and What are the Complications of Untreated Diabetes?

Diabetes affects the body’s ability to produce or use insulin effectively, leading to elevated blood sugar levels. Over time, this can damage blood vessels and organs, leading to various health complications. 

In both cases, untreated diabetes leads your body exposed to high blood sugar, which can result in serious complications.

Some of the common complications are as follows:

Short-Term Complications Long-Term Complications
Hypoglycemia (Low blood sugar) Cardiovascular Disease
Hyperglycemia (High blood sugar) Kidney Damage (Nephropathy)
Diabetic Ketoacidosis Eye Damage (Retinopathy)
Hyperosmolar Hyperglycemic State Nerve Damage (Neuropathy)
Foot and Skin Complications

Acute Complications

Chronic Complications

Can Diabetes Be Prevented?

Diabetes is often seen more as a result of lifestyle choices than a disease. It’s important not to let it cause too much fear or worry. Stress can make diabetes worse, so managing your lifestyle well is key. 

Type 2 diabetes can often be prevented or delayed with healthy lifestyle changes, such as maintaining a healthy weight, eating a balanced diet, and exercising regularly. However, Type 1 diabetes cannot be prevented as it’s largely due to genetic and unknown factors, but you can manage it well with lifestyle modifications, proper diet and medications.
