Discover what causes Diabetes Type 2 and how to prevent it. Learn lifestyle factors, risks, and habits that contribute to this condition.🤯🔥💥

Diabetes mellitus develops when the pancreas cannot produce enough insulin or the body cannot effectively utilize the insulin it produces. There are two main types of diabetes: type 1 and type 2. Type 1 diabetes results from the autoimmune destruction of insulin-producing cells. Type 2 diabetes occurs when insulin resistance impairs glucose regulation, or the pancreas secretes too little insulin. While genetics and age increase the risk, an unhealthy diet, obesity, inactivity, high blood pressure, prediabetes, abnormal cholesterol, and socioeconomic factors compound the causes of this chronic disease that affects over 400 million worldwide.

What Causes of Type 2 Diabetes

Key Takeaways

  • Type 2 diabetes impairs your body’s ability to use insulin effectively or produce enough insulin, leading to high blood sugar levels.
  • Often termed “adult-onset,” it primarily affects individuals over 40, though lifestyle factors like diet and exercise habits can trigger it at any age.
  • Obesity, especially excess fat in the midsection, significantly heightens the risk of developing type 2 diabetes, with weight gain during adolescence or midlife being particularly detrimental​1​.
  • Genetics, unhealthy diet choices, lack of physical activity, and obesity are key factors contributing to diabetes.
  • Identifying these causes helps us make informed decisions about our well-being.
  • By adopting a balanced diet, engaging in regular exercise, and leading a healthy lifestyle overall, we can reduce the risk of developing diabetes.

What is Diabetes?

What is Diabetes?

Diabetes is a chronic disease that affects how the body processes sugar. It occurs when the pancreas cannot produce enough insulin or the body cannot properly use the insulin it produces. There are three main types of diabetes: type 1, type 2, and gestational diabetes.

Types of Diabetes

Types of Diabetes

Type 1 diabetes is an autoimmune condition in which the immune system destroys insulin-producing cells. It usually appears in childhood or adolescence and requires insulin injections for management. The exact cause of type 1 diabetes is unknown, though it may involve genetic and environmental factors.

Type 2 diabetes is the most common form, accounting for 90-95% of cases. It occurs when the body develops insulin resistance, impairing its ability to use insulin effectively, or the pancreas produces too little insulin.

Understanding the Causes: What Causes Type 1 Diabetes?

  • Autoimmune attack. In type 1 diabetes, the body’s immune system mistakenly attacks and destroys the cells in the pancreas that make insulin.
  • Genetic factors. The genes you inherit from your parents can play a role in whether or not you develop this disease, but they don’t determine whether or not it will happen to you–they only increase your risk of developing it if other factors are present.
  • Environmental factors (such as viruses). Viruses may also trigger an autoimmune response in some people genetically predisposed to developing type 1 diabetes; however, this has yet to be proven by research studies on humans so far!

Understanding the Causes: How Type 2 Diabetes Develops

When discussing health conditions, it’s essential to start with their origins. For instance, type 2 diabetes is a common condition, but what causes it? It all begins with our body’s ability to process glucose from our blood.

Our pancreas produces a hormone called insulin, which is crucial in regulating our blood sugar levels. With type 2 diabetes, the body either resists the effects of insulin or doesn’t produce enough of it to maintain a normal blood glucose level. This condition is the most common type of diabetes, hence the importance of understanding its causes.

What Causes Type 2 Diabetes?

Type 2 diabetes is the most common form, accounting for about 90-95% of cases. It occurs when the body develops insulin resistance, impairing its ability to use insulin effectively, or the pancreas produces too little insulin. The main causes of type 2 diabetes include:

Obesity or excess weight

Extra fat, especially in the midsection, can lead to insulin resistance and higher diabetes risk. Excess weight gain during adolescence or midlife also increases the likelihood of developing type 2 diabetes.

Unhealthy diet

A diet high in sugar, refined carbs, red meat, and full-fat dairy products can contribute to insulin resistance and high blood sugar levels over time. Lack of fiber, vegetables, and lean protein also promotes diabetes development.

Lack of exercise

Leading a sedentary lifestyle without regular physical activity allows insulin resistance and excess weight gain to occur, raising the risk of type 2 diabetes.


As people get older, especially after age 45, the risk of developing type 2 diabetes increases. Aging decreases insulin sensitivity and secretion.

Family history

Having a parent or sibling with diabetes increases your odds of developing the disease by 2-8 times. Genetics play a significant role in type 2 diabetes.


African Americans, Latinos, Native Americans, and Asian Americans are at higher risk of type 2 diabetes than non-Hispanic whites. This is partly due to a higher prevalence of obesity and excess weight gain within these groups.

History of gestational diabetes

Women who develop high blood sugar levels during pregnancy have a 35-60% chance of developing diabetes later in life.

Impaired glucose metabolism

Prediabetes, impaired fasting glucose, or impaired glucose tolerance damage insulin sensitivity and beta cell function, making progression to diabetes more likely.

High blood pressure

Having uncontrolled high blood pressure can damage blood vessels and nerves involved in glucose regulation, increasing the risk of developing diabetes complications and health issues.

Abnormal cholesterol levels

High triglycerides and low HDL cholesterol contribute to insulin resistance and inflammation in the body, promoting diabetes development over time.

What Causes Gestational Diabetes?

The exact cause of gestational diabetes is unknown. However, some factors can increase your risk of developing it:

  • Hormone changes during pregnancy
  • Insulin resistance (the body’s inability to use insulin properly)
  • High blood sugar levels

What Are the Risk Factors for Diabetes?

There are many risk factors for diabetes. These include:

  • Family history of type 2 diabetes
  • Age (the older you are, the more likely it is that you will develop type 2 diabetes)
  • Obesity (being overweight or obese)
  • Physical inactivity (not being active enough)
  • Poor diet (eating too much sugar and fat)
  • Smoking cigarettes/tobacco products
  • High blood pressure (hypertension)
  • High cholesterol levels in your blood

Symptoms and Diagnosis of Type 2 Diabetes

Recognizing the signs and symptoms of type 2 diabetes can be a lifesaver. The illness often begins with insulin resistance, where cells in the muscles, liver, and fat do not use insulin well. Over time, the demand for insulin rises, and when the pancreas can’t make enough insulin to overcome this resistance, blood sugar levels rise.

Common symptoms include frequent urination, increased thirst, and unexplained weight loss. If you have these symptoms, it’s essential to seek medical advice. Early diagnosis of diabetes can prevent complications later on.

Managing and Treating Type 2 Diabetes

Being diagnosed with type 2 diabetes can be overwhelming, but it’s important to remember that it’s a manageable condition. With a well-structured treatment plan and a commitment to lifestyle changes, you can control your blood sugar levels effectively.

Treatment for type 2 diabetes typically involves lifestyle changes like healthier eating and regular exercise. Medication may also be necessary to control blood sugar levels. In some cases, insulin therapy may be recommended.

Remember, successful diabetes management is a marathon, not a sprint. It involves regular check-ups, monitoring your blood glucose levels, and being mindful of any potential complications such as kidney disease.

Prevention: Reducing Your Risk Factors for Type 2 Diabetes

Prevention is always better than cure. Certain risk factors increase the likelihood of developing type 2 diabetes. These include obesity, lack of physical activity, and genetics. However, with some changes to your lifestyle, you can reduce these risks.

Regular physical activity, maintaining a healthy weight, and eating a balanced diet can all contribute to preventing type 2 diabetes. It’s also important to regularly check your blood sugar levels if you’re at a higher risk of developing type 2 diabetes.

What Are the Complications of Diabetes?

Many complications of diabetes can lead to serious health problems. These include:

  • Heart disease, stroke, and other cardiovascular problems: High blood sugar can damage the walls of your arteries. This increases your risk of heart attack and stroke.
  • Kidney disease: Diabetes makes it hard for your kidneys to filter waste from your blood, which can lead to kidney failure or chronic kidney disease (CKD).
  • Nerve damage: Nerves in the feet may be damaged by high blood sugar over time. This causes tingling or numbness in the feet and pain when walking or exercising on hard surfaces like concrete floors or pavement–a condition called neuropathy that may make it difficult to perform daily tasks such as driving a car or going upstairs without assistance from another person.

How is Diabetes Treated?

How is Diabetes Treated?

There are several treatment options for diabetes. These include medications, insulin therapy, and lifestyle changes. Medications can help lower blood sugar levels by increasing the insulin released from your pancreas or decreasing how much sugar is absorbed from food into your bloodstream.
Insulin therapy involves injecting yourself with insulin to control symptoms of type 1 and type 2 diabetes mellitus (T1DM & T2DM).
Lifestyle changes include eating healthy foods, exercising regularly, and losing weight if overweight or obese. Monitoring blood sugar levels periodically helps you track how well these treatments work.
