What is Type 2 Diabetes?
Type 2 diabetes is a chronic metabolic disorder where the body develops insulin resistance or the pancreas cannot produce enough insulin. This leads to uncontrolled high blood sugar levels and can cause various health complications over time. Type 2 diabetes typically occurs in adults, but nowadays, it can also be diagnosed in younger individuals due to inactive lifestyles and unhealthy diets.
What are the Symptoms of Type 2 Diabetes?
The symptoms of Type 2 diabetes develop over time and may initially go unnoticed in some individuals. The most common symptoms include:
- Excessive thirst and dry mouth
- Frequent urination (polyuria)
- Increased hunger (polyphagia)
- Persistent fatigue and weakness
- Blurred vision
- Slow-healing cuts and wounds
- Numbness or tingling in the hands and feet (paresthesia)
What are the Causes of Type 2 Diabetes?
Both genetic and environmental factors play a role in the development of Type 2 diabetes. The main risk factors include:
- Genetic predisposition: A family history of diabetes increases the risk.
- Lack of exercise (sedentary lifestyle): Regular physical activity is important for insulin sensitivity. Lack of exercise can increase insulin resistance.
- Unhealthy diet: Excessive consumption of carbohydrates and sugar can raise blood sugar levels.
- Obesity: Being overweight is one of the main causes of insulin resistance.
- Older age: Insulin sensitivity can decrease with age.
- Stress and sleep disorders: These can disrupt hormonal balance and increase insulin resistance.
How is Type 2 Diabetes Diagnosed?
Various tests are conducted to diagnose Type 2 diabetes:
- Fasting Blood Sugar Test: A reading of 126 mg/dL or higher after an 8-hour fast can indicate diabetes.
- A1c Test (Hemoglobin A1c Test / Long-Term Blood Sugar Test): This test shows the average blood sugar levels over the past 3 months. Values of 6.5% or higher suggest diabetes.
- Oral Glucose Tolerance Test (OGTT): After drinking a sugary solution, blood sugar levels are measured at specific time intervals. A reading of 200 mg/dL or higher after 2 hours indicates diabetes.
Treatment Methods for Type 2 Diabetes
The treatment of Type 2 diabetes involves patient lifestyle changes combined with medication therapy:
- Dietary Changes / Healthy Eating: A healthy and balanced diet plays a crucial role in controlling blood sugar levels.
- Regular Exercise / Physical Activity: It is recommended to burn an average of 700 kcal per week through exercise, with at least 3 days per week and a total of 150 minutes of moderate activity (with each session lasting at least 10 minutes).
- Medication Therapy: Oral antidiabetic drugs or injectable therapies with insulin and GLP-1 receptor agonists may be used.
- Blood Sugar Monitoring / Glucose Control: Regular blood glucose checks are essential for diabetes management.
Differences Between Type 1 and Type 2 Diabetes
Type 1 and Type 2 diabetes are two distinct forms of diabetes with different underlying mechanisms:
|
Feature |
Type 1 Diabetes |
Type 2 Diabetes |
|
Age of Onset |
Typically starts in children or young adults |
Usually occurs in adults, but can also affect younger people |
|
Cause |
The immune system attacks the insulin-producing cells in the pancreas |
The body develops insulin resistance or doesn’t produce enough insulin |
|
Insulin Needs |
Lifelong insulin therapy is necessary |
Medications, lifestyle changes, and in some cases, insulin therapy are possible |
|
Symptoms |
Rapid onset, excessive thirst, frequent urination, sudden weight loss |
Develops slowly, frequent urination, excessive thirst, fatigue, weight gain, and blurred vision |
Frequently Asked Questions
What is the main difference between Type 1 and Type 2 diabetes?
Type 1 diabetes is an autoimmune disease where the body completely stops producing insulin. In Type 2 diabetes, while insulin is still produced, there’s often a defect in insulin secretion due to a problem with various bodily processes, leading to insulin resistance.
Do you have to use insulin with Type 2 diabetes?
For most patients, lifestyle changes and oral medications are sufficient initially. However, insulin therapy may become necessary for patients whose A1c level is not within the target range or who have uncontrolled blood sugar levels.
What are the treatment goals for Type 2 diabetes?
The target A1c level should be below 7%, fasting finger prick blood sugar readings should be between 80-130 mg/dL, and finger prick blood sugar readings 2 hours after eating should be below 160 mg/dL.
Is Type 2 diabetes dangerous?
If left uncontrolled, Type 2 diabetes can lead to serious complications such as heart disease, kidney failure, vision loss, and diabetic foot ulcers.
Does Type 2 diabetes lead to weight gain?
Some medications used to treat diabetes can cause weight gain. However, this risk can be reduced through a healthy diet and exercise.
Is there a genetic component to Type 2 diabetes?
Yes, individuals with a family history of Type 2 diabetes have a higher risk of developing the condition.
