Diabetes: Understanding the Causes, Symptoms, and Management


Diabetes is a prevalent chronic health condition affecting millions of people worldwide. In this the body struggles to regulate blood sugar levels effectively. This article aims to delve into the causes, symptoms, and effective management strategies for diabetes.

What is Diabetes? / Definition of Diabetes: 

A metabolic disorder characterized by high blood sugar levels is called Diabetes. It arises from either insufficient production of insulin or the body’s inability to utilize insulin properly. Insulin, a vital hormone produced by the pancreas, plays a critical role in the regulation of blood sugar levels.

What is normal sugar level by age?

The normal sugar levels can vary by age and depend on whether a person has diabetes or not. Here are the general guidelines for normal blood sugar levels based on age:

For non-diabetic individuals:

  1. Children (age 6-12): Fasting blood sugar level should be between 70-100 mg/dL (3.9-5.6 mmol/L), and postprandial (after meals) blood sugar level should be less than 140 mg/dL (7.8 mmol/L).
  2. Adults (age 18 and older): Fasting blood sugar level should be between 70-100 mg/dL (3.9-5.6 mmol/L), and postprandial blood sugar level should be less than 140 mg/dL (7.8 mmol/L).

For individuals with diabetes, the target blood sugar levels may vary based on age, overall health, and individual circumstances. It is important to work with a healthcare professional to establish personalized blood sugar targets.

It is worth noting that blood sugar levels can fluctuate throughout the day and can be affected by various factors such as diet, physical activity, stress, and medication. Regular monitoring and consultation with a healthcare professional are essential for managing blood sugar levels effectively.

Types of Diabetes:

  • Type 1 Diabetes: In the case of type 1 diabetes, an autoimmune disorder occurs where the immune system mistakenly targets and eliminates the pancreatic cells responsible for producing insulin. It typically develops in childhood or early adulthood and requires regular insulin therapy for proper blood sugar management.
  • Type 2 Diabetes: The most common form of diabetes is the Type 2 Diabetes, accounting for the majority of cases. It usually occurs in adulthood, but its prevalence is increasing among children and adolescents. In this type, the body becomes resistant to insulin or fails to produce enough of it. Lifestyle factors such as obesity and a sedentary lifestyle significantly contribute to its development.
  • Gestational Diabetes: Gestational diabetes affects pregnant women who did not have diabetes before. During pregnancy, hormonal shifts can result in a condition known as insulin resistance, where the body’s response to insulin is reduced. Although gestational diabetes usually resolves after delivery, women who develop it have a higher risk of developing type 2 diabetes later in life.

Causes and Risk Factors of Diabetes:

The causes of diabetes vary depending on the type:

Type 1 diabetes: The exact cause is unknown, but a combination of genetic and environmental factors is believed to be involved.

Type 2 diabetes: Lifestyle factors like poor diet, physical inactivity, obesity, and genetic predisposition increase the risk of developing type 2 diabetes.

Gestational diabetes: Hormonal changes during pregnancy contribute to insulin resistance.

Symptoms of Diabetes:

The symptoms of diabetes may vary, but some common signs include:

  • Increased thirst and frequent urination
  • Fatigue and lethargy
  • Unexplained weight loss
  • Blurred vision
  • Slow wound healing
  • Recurring infections
  • Numbness or tingling in the hands or feet

Preventive measures for Diabetes:

Preventive measures for diabetes involve adopting a healthy lifestyle and making certain changes to reduce the risk of developing the condition. Here are some key preventive measures for diabetes:

  1. Maintain a Healthy Weight: Achieving and maintaining a healthy weight is important to reduce the risk of type 2 diabetes. By adopting a balanced diet and engaging in regular exercise, you can work towards maintaining a body mass index (BMI) within the normal range of 18.5-24.9. This healthy weight range helps lower the chances of developing diabetes and promotes overall well-being.
  2. Follow a Balanced Diet: Adopt a diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats. Making conscious choices about your diet can play a significant role in preventing diabetes. It is advisable to limit the consumption of processed foods, sugary beverages, and foods that are high in saturated and trans fats. Instead, opt for foods with a low glycemic index, which can help regulate blood sugar levels more effectively. By being mindful of your food choices and focusing on nutritious options, you can take proactive steps towards reducing the risk of developing diabetes and promoting better health.
  3. Engage in Regular Physical Activity: Regular exercise helps improve insulin sensitivity and control weight. Aim for at least 30 minutes of moderate-intensity aerobic activity, such as brisk walking or cycling everyday.
  4. Limit Sedentary Behavior: Reduce sedentary activities such as prolonged sitting or watching TV. Take breaks, stand up, and move around regularly throughout the day. Physical activity is a must into your daily routine whenever possible.
  5. Avoid Tobacco Use: Smoking increases the risk of developing diabetes and other health complications. If you smoke, consider quitting. Seek support from healthcare professionals.
  6. Limit Alcohol Consumption: Excessive alcohol consumption can contribute to weight gain and increase the risk of developing type 2 diabetes.
  7. Manage Stress: Incorporating stress-reducing techniques into your daily routine is crucial for diabetes prevention. Take time to engage in activities that bring you joy and help you relax, such as deep breathing exercises, meditation, yoga, or pursuing hobbies that you enjoy. These practices can effectively lower stress levels and contribute to overall well-being. By prioritizing self-care and finding healthy outlets for stress, you can enhance your resilience and reduce the risk of developing diabetes, leading to a healthier and more balanced life.
  8. Get Regular Check-ups: Regular health check-ups allow healthcare professionals to monitor your overall health and assess your risk for developing diabetes. Follow their recommendations for screenings and tests related to diabetes.
  9. Know Your Family History: If you have a family history of diabetes, you may have a higher risk. Be aware of your family’s medical history and discuss it with your healthcare provider. They can provide guidance on preventive measures specific to your situation.

Remember, while these preventive measures can reduce the risk of developing diabetes, they do not guarantee complete prevention. It is important to stay vigilant, be aware of the early signs and symptoms of diabetes, and seek medical advice if you experience any concerning symptoms.

Diagnosis and Treatment of Diabetes:

Diabetes can be diagnosed through various tests, including fasting blood sugar, oral glucose tolerance test, and HbA1c levels. Once diagnosed, the primary goal of treatment is to effectively manage blood sugar levels. Treatment options include:

Type 1 diabetes: Regular insulin injections, frequent blood sugar monitoring, and adherence to a healthy meal plan.

Type 2 diabetes: Lifestyle modifications such as adopting a balanced diet, engaging in regular physical exercise, weight loss, oral medications, and, in some cases, insulin therapy.

Gestational diabetes: Monitoring blood sugar levels, maintaining a healthy diet, and occasionally requiring insulin injections.
