Type 2 Diabetes: Causes, Symptoms, and Treatment

by RawalKhan

Type 2 diabetes is a prevalent chronic condition that changes the way your body handles blood sugar, and it represents 90–95% of all diabetes cases. Not limited by age, this disease is increasingly being diagnosed in children, teenagers, and young adults, though it most commonly affects those over 45.

If you’re navigating the complexities of type 2 diabetes, understanding how your cells become insulin resistant and why your pancreas might fail to produce adequate insulin can be crucial. This article aims to illuminate the pathogenesis of diabetes, delineating causes, symptoms, and potential treatments to manage this condition effectively.

Type 2 Diabetes

1. Understanding Type 2 Diabetes:

  • Insulin Resistance and Insulin Production: A central issue in type 2 diabetes is insulin resistance, where cells in muscle, fat, and the liver don’t respond effectively to insulin. Consequently, your pancreas tries to compensate by producing more insulin. Over time, however, the pancreas is unable to keep up, leading to increased blood sugar levels.
  • Impact on Health: Elevated blood sugar can have detrimental effects on various organs. It can lead to complications such as heart disease, vision loss, and kidney disease, making the management of type 2 diabetes critical for maintaining overall health.
  • Prevalence and Preventability: While type 2 diabetes is a widespread condition, accounting for 90–95% of all diabetes cases, it’s important to note that up to 9 in 10 cases could be prevented. Lifestyle changes play a significant role in the prevention of this chronic disease.
  • Rising in Youth: Alarmingly, the rates of childhood obesity have been climbing, which has led to more young people being diagnosed with type 2 diabetes. This underscores the importance of addressing lifestyle factors from an early age to mitigate the risk.
  • Organ System Involvement: Type 2 diabetes doesn’t just affect blood sugar levels; it’s a systemic condition that can impact major organs, including the heart, blood vessels, nerves, eyes, and kidneys. This broad range of effects highlights the need for comprehensive management strategies.

By understanding these key aspects, you can better grasp the complexity of type 2 diabetes and the importance of early intervention and management.

2. Causes and Risk Factors:

Understanding the various factors that contribute to the development of type 2 diabetes is essential for both prevention and management. Several important risk factors are listed below:

Age and Lifestyle Factors:

  • As you age, particularly after 45 years, the risk of developing type 2 diabetes increases.
  • A sedentary lifestyle, characterized by physical inactivity, can lead to weight gain and obesity, significantly elevating diabetes risk.
  • Lifestyle choices such as a diet high in fats and sugars, excessive alcohol consumption, and smoking are also contributing factors.

Genetic and Physiological Influences:

  • If you have a family history of diabetes, especially if a parent or sibling has the condition, your risk is higher.
  • Prediabetes is a critical stage where blood sugar levels are elevated but not high enough for a diabetes diagnosis, often leading to type 2 diabetes if not addressed.

Weight and Health Conditions:

  • Being overweight or obese is the single most important cause of type 2 diabetes, especially if the fat is primarily stored in the abdomen.
  • High blood pressure, abnormal cholesterol levels, and having had gestational diabetes or giving birth to a baby over 9 pounds are indicators of increased diabetes risk.
  • Chronic stress and a lack of quality sleep may also contribute to the development of type 2 diabetes.

Ethnicity and Other Factors:

  • Certain racial and ethnic groups, such as African Americans, Hispanic or Latino Americans, and some Asian Americans, are at a higher risk.
  • People of Asian heritage may be at risk even at a lower BMI due to higher levels of visceral fat.
  • Long-term use of certain medications, including corticosteroids, can increase the risk.
  • Members of the LGBT community may face an increased risk due to behaviors linked to minority stress.

[blockquote align=”none” author=””]It’s important to note that while these factors can increase your risk, type 2 diabetes is a complex condition with multiple contributors. If you identify with one or more of these risk factors, it’s advisable to consult a healthcare professional for evaluation and potential preventive measures.[/blockquote]

3. Symptoms and Diagnosis:

Recognizing the symptoms of type 2 diabetes is crucial, as they can be mild and easy to overlook. If you experience any of the following symptoms, it’s important to consult with a healthcare provider for a proper diagnosis:

  • Increased thirst and frequent urination are due to the excess glucose in your bloodstream pulling fluid from your tissues.
  • Increased hunger, particularly after eating, because of the lack of insulin to move glucose into your cells.
  • Unintended weight loss occurs when your body starts burning fat and muscle for energy due to insufficient sugar moving into your cells.
  • Fatigue, since your cells are deprived of glucose, leaves you more tired than usual.
  • Blurred vision occurs when high blood sugar levels pull fluid from your lenses, affecting your ability to focus.
  • Slow-healing sores or frequent infections, which can be a result of high blood sugar levels affecting your body’s natural healing process and resistance to infections.
  • Numbness or tingling in your hands or feet could be a sign of nerve damage caused by prolonged high blood sugar levels.

Diagnosis of type 2 diabetes involves a series of blood tests, which may include:

  • A1C Test: This test provides an average blood sugar level over the past 2–3 months. An A1C level of 5.7% or higher signals prediabetes, while 6.5% or higher on two separate tests indicates diabetes.
  • Fasting Plasma Glucose Test: After an 8-hour fast, blood sugar levels are measured. When 126 mg/dL or more is detected, diabetes may be suspected.
  • Oral Glucose Tolerance Test: Blood sugar is tested before and 2 hours after consuming a sugary drink. A level of 200 mg/dL or higher after 2 hours points to diabetes.
  • Random Plasma Glucose Test: Blood sugar is measured at any time of the day, without regard to when you last ate. A level of 200 mg/dL or higher indicates diabetes, especially if it is accompanied by symptoms of high blood sugar.

[blockquote align=”none” author=””]The American Diabetes Association recommends routine screening for adults age 35 or older, or earlier if you are overweight and have additional risk factors. It is recommended to repeat screenings at least every three years. After diagnosis, additional tests may be conducted to differentiate between type 1 and type 2 diabetes and to check for any complications. It’s also advised to monitor your A1C levels regularly, with a general target below 7% for most individuals with diabetes. Regular screening is especially important if you have risk factors such as being over age 45, a family history of diabetes, or a history of gestational diabetes.[/blockquote]

4. Management and Treatment:

When it comes to managing and treating type 2 diabetes, a comprehensive approach is necessary to maintain blood sugar levels and overall health. Here are the key components of an effective management plan:

Lifestyle Modifications:

  • Healthy Eating: Your diet should focus on foods that improve weight management, blood pressure, and insulin sensitivity. Make sure to incorporate a range of whole grains, lean proteins, fruits, and vegetables.
  • Regular Exercise: Aim for at least 150 minutes of moderate aerobic activity or 75 minutes of vigorous aerobic activity per week, along with strength training twice a week. This can enhance the body’s response to insulin and help control blood sugar levels.
  • Weight Management: If overweight, reducing body weight by 5–10% can significantly improve diabetes control and reduce the risk of other health issues.

Medications and Therapies:

  • Injectable Medications: In some cases, GLP-1 receptor agonists or insulin therapy may be necessary to maintain blood sugar levels within the target range.
  • Insulin Therapy: For individuals with a higher BMI or those with obesity-related health conditions, insulin therapy may be introduced to the treatment plan.

Regular Monitoring and Check-ups:

  • Blood Sugar Levels: Monitoring is crucial; regular checks will help ensure levels are within the goal range set by your doctor.
  • Blood Pressure and Cholesterol: Keep these levels close to the targets set by your healthcare provider to minimize the risk of complications.
  • Routine Screenings: Regular medical check-ups, including eye exams and foot inspections, can help prevent the progression of diabetes-related complications.

Special Considerations:

  • Pregnancy: Women with type 2 diabetes need to adjust their treatment plan and monitor carbohydrate intake to manage blood sugar levels during pregnancy.
  • Emergency Situations: Be vigilant for symptoms of high blood sugar, HHNS, diabetic ketoacidosis, and low blood sugar, and seek immediate medical attention if they occur.

[blockquote align=”none” author=””]Remember, the main goals of treating type 2 diabetes are to keep blood sugar levels within the desired range, address other medical conditions, and quit smoking if applicable. By adhering to these management strategies, you can significantly improve your quality of life and reduce the risk of diabetes-related complications.[/blockquote]
