What is diabetes?
Diabetes is a chronic disease that occurs when a person is unable to produce enough insulin or use the insulin produced effectively. Insulin is a hormone produced by the pancreas that helps regulate blood sugar (glucose) levels and allows glucose to enter cells and be used for energy.
Diabetes Causes
There are four main types of diabetes:
1. Type 1 Diabetes: The exact cause of type 1 diabetes is not fully known, but a combination of genetic predisposition and environmental factors are involved. In type 1 diabetes, the immune system attacks and destroys the insulin-producing beta cells of the pancreas. This autoimmune response results in a significant reduction or complete absence of insulin production. While genetic factors play a role in susceptibility to type 1 diabetes, certain triggers, such as viral infections or dietary factors, may also contribute to the development of the disease.
2. Type 2 Diabetes: Type 2 diabetes occurs when the body becomes resistant to the effects of insulin or does not produce enough insulin to maintain normal blood sugar levels. The exact cause of type 2 diabetes is multifactorial and may include:
- Genetics: Family history and genetic predisposition may increase the risk of type 2 diabetes. Certain genetic variants can affect insulin production, insulin sensitivity, and other factors related to glucose metabolism.
- Lifestyle factors: Poor eating habits, sedentary lifestyle, and obesity are important risk factors for type 2 diabetes. Consuming a diet high in processed foods, sugar, and high fat, as well as lack of physical activity, can lead to weight gain and insulin resistance, both leading causes of type 2 diabetes.
- Age and Race: As age increases, certain races are at higher risk for type 2 diabetes, including African American, Hispanic, Native American, and Asian American populations.
- Other medical conditions: Certain medical conditions, such as prediabetes, polycystic ovary syndrome (PCOS), and metabolic syndrome, may increase your risk of developing type 2 diabetes.
3. Gestational diabetes: Gestational diabetes occurs during pregnancy and is believed to be caused by hormonal changes and insulin resistance associated with pregnancy. Women who are overweight, have a family history of diabetes, or are over 25 years of age are at higher risk of developing gestational diabetes.
4. Other forms of diabetes: Less common forms of diabetes, such as monogenic diabetes and secondary diabetes, are caused by certain genetic mutations, underlying conditions (e.g. pancreatic disease, hormonal disorders), or medications (e.g. corticosteroids, antipsychotic drugs).
Although genetic factors overall can affect the risk of developing diabetes, lifestyle factors such as diet, physical activity, and weight play a role in developing type 2 diabetes, the most common form.
Managing Diabetes
Managing diabetes requires a multifaceted approach aimed at controlling blood sugar levels, preventing complications, and promoting overall health and well-being. Here are some steps you can take to effectively manage your diabetes:
- Monitor blood sugar levels: Regularly check your blood sugar levels as recommended by your healthcare provider using a blood glucose meter or continuous monitoring system. Tracking your blood sugar levels helps you understand how food, physical activity, medications, and other factors affect your blood sugar levels.
- Healthy diet: Follow a balanced diet rich in fruits, vegetables, whole grains, and lean proteins. Limit your intake of sugary foods, processed foods, refined carbohydrates, and saturated fats.
- Regular physical activity: Engage in regular exercise to control blood sugar levels, improve insulin sensitivity, and manage weight. Aim for at least 150 minutes of moderate-intensity aerobic activity or 75 minutes of vigorous-intensity activity per week, along with strength training at least two days per week.
- Watch for complications: Be vigilant for signs and symptoms of diabetes-related complications such as neuropathy, nephropathy, retinopathy, and cardiovascular disease. Schedule regular health checkups, including eye exams, foot exams, and tests for kidney function and heart health.
- Maintain weight: Achieve and maintain a healthy weight to improve insulin sensitivity and blood sugar control. If you are overweight or obese, even a small amount of weight loss can have significant benefits for managing diabetes.
- Manage stress: Practice stress management techniques such as relaxation techniques, meditation, deep breathing exercises, and engaging in enjoyable hobbies and activities.
- Quit smoking: Quitting smoking is crucial for managing diabetes and reducing the risk of complications such as cardiovascular disease.
- Get enough sleep: Aim for 7 to 9 hours of quality sleep each night. Inadequate sleep can affect blood sugar levels and insulin sensitivity.
By incorporating these strategies into your daily life and effectively managing your diabetes, you can reduce the risk of complications while improving your overall quality of life.
