Diabetes

1. Diabetes

Diabetes mellitus, commonly known as diabetes, is a chronic metabolic disease characterized by elevated levels of blood glucose (blood sugar), which leads over time to serious damage to the heart, blood vessels, eyes, kidneys, and nerves. The disease occurs either when the pancreas does not produce enough insulin or when the body cannot effectively use the insulin it produces.

1. 1. Types of Diabetes

There are three main types of diabetes:

• Type 1 Diabetes: This is an autoimmune disease, meaning the body's immune system mistakenly attacks and destroys the insulin-producing cells (beta cells) in the pancreas. People with Type 1 diabetes require lifelong insulin therapy to survive. It typically develops in childhood or adolescence, but can occur at any age. Often, the onset is relatively rapid. Immune System
• Type 2 Diabetes: This is the most common form of diabetes, usually developing in adulthood, though increasingly seen in children and adolescents due to rising obesity rates. In Type 2 diabetes, the body becomes resistant to the effects of insulin, and the pancreas may not be able to produce enough insulin to overcome this resistance. Lifestyle factors like obesity, inactivity, and genetics play a significant role. The development is usually gradual. Obesity Genetics
• Gestational Diabetes: This type develops during pregnancy in women who did not previously have diabetes. It is caused by hormonal changes during pregnancy that can lead to insulin resistance. While usually resolving after childbirth, it increases the mother's risk of developing Type 2 diabetes later in life. It also affects the baby, potentially leading to complications during birth and increased risk of obesity and Type 2 diabetes in the child's later life. Pregnancy

Less common types include monogenic diabetes (caused by mutations in a single gene) and diabetes resulting from other causes such as certain medications or medical conditions.

1. 1. Symptoms of Diabetes

Symptoms of diabetes can vary depending on the type and severity of the condition. Some common symptoms include:

• Frequent Urination: Especially at night (polyuria). High blood sugar levels cause the kidneys to work harder to filter and absorb excess glucose. If the kidneys can't keep up, the excess glucose is excreted in the urine, drawing water with it.
• Excessive Thirst: (polydipsia). Due to the frequent urination, the body becomes dehydrated, leading to increased thirst.
• Unexplained Weight Loss: Despite eating normally or even more than usual. In Type 1 diabetes, the body cannot get glucose into cells for energy, so it begins to break down muscle and fat for fuel. In Type 2 diabetes, the body may not utilize glucose effectively.
• Increased Hunger: (polyphagia). The body's cells are not getting enough energy from glucose, leading to persistent hunger.
• Blurry Vision: High blood sugar levels can cause fluid to be pulled from the lenses of the eyes, affecting their ability to focus.
• Slow-Healing Sores: High blood sugar impairs blood flow and nerve function, hindering the healing process.
• Frequent Infections: High blood sugar weakens the immune system, making individuals more susceptible to infections.
• Fatigue: Lack of glucose in cells leads to feelings of tiredness and weakness.
• Numbness or Tingling in Hands or Feet: (neuropathy). High blood sugar can damage nerves, leading to these sensations.
• Dry, Itchy Skin: Can be a sign of dehydration or poor circulation.

It’s important to note that some people, particularly those with Type 2 diabetes, may have no noticeable symptoms for a long time. This is why regular screening is crucial, especially for those with risk factors. Health Screening

1. 1. Causes and Risk Factors

The causes of diabetes vary depending on the type.

• Type 1 Diabetes: The exact cause is unknown, but it’s believed to involve an autoimmune reaction triggered by genetic predisposition and environmental factors, such as viral infections.
• Type 2 Diabetes: A combination of genetic predisposition and lifestyle factors is the primary cause. Risk factors include:

   *   Obesity: Especially abdominal obesity.
   *   Physical Inactivity:  A sedentary lifestyle increases insulin resistance.
   *   Family History:  Having a parent or sibling with Type 2 diabetes increases your risk.
   *   Age: The risk increases with age, particularly after age 45.
   *   Ethnicity: Certain ethnic groups (African Americans, Hispanic Americans, Native Americans, Asian Americans, and Pacific Islanders) are at higher risk.
   *   Prediabetes: Having blood sugar levels higher than normal, but not high enough to be diagnosed as diabetes.  Prediabetes
   *   Gestational Diabetes:  A history of gestational diabetes increases the risk of developing Type 2 diabetes.

• Gestational Diabetes: Hormonal changes during pregnancy can cause insulin resistance. Women with obesity, a family history of diabetes, or who are of certain ethnicities are at higher risk.

1. 1. Diagnosis

Diabetes is diagnosed through blood tests that measure blood glucose levels. Common tests include:

• Fasting Plasma Glucose (FPG): Measures blood glucose after an overnight fast. A reading of 126 mg/dL or higher on two separate tests indicates diabetes.
• A1C Test: Measures your average blood glucose level over the past 2-3 months. An A1C of 6.5% or higher indicates diabetes. A1C
• Oral Glucose Tolerance Test (OGTT): Measures blood glucose levels before and 2 hours after drinking a sugary drink. A reading of 200 mg/dL or higher after 2 hours indicates diabetes.
• Random Plasma Glucose (RPG): Measures blood glucose at any time of day. A reading of 200 mg/dL or higher, along with symptoms of diabetes, can indicate diabetes.

1. 1. Treatment

The goal of diabetes treatment is to manage blood glucose levels and prevent complications. Treatment strategies vary depending on the type of diabetes.

• Type 1 Diabetes: Requires lifelong insulin therapy, delivered through injections, an insulin pump, or inhaled insulin. Regular blood glucose monitoring, carbohydrate counting, and a healthy diet are also essential. Insulin Pump
• Type 2 Diabetes: Treatment often begins with lifestyle modifications, including:

   *   Diet:  A healthy diet low in processed foods, sugary drinks, and saturated fats, and rich in fruits, vegetables, and whole grains. Healthy Diet
   *   Exercise:  Regular physical activity improves insulin sensitivity and helps manage weight. Physical Exercise
   *   Weight Loss:  Losing even a small amount of weight can significantly improve blood glucose control.
   If lifestyle changes are not enough, medications may be prescribed, including:
       *   Oral Medications:  Various types of oral medications work in different ways to lower blood glucose levels.
       *   Injectable Medications:  Some medications are injected, such as GLP-1 receptor agonists, which can also promote weight loss.
       *   Insulin:  May be needed if other treatments are not effective.

• Gestational Diabetes: Treatment typically involves dietary changes and regular exercise. If these are not enough, insulin or oral medications may be prescribed. Close monitoring of blood glucose levels is crucial.

1. 1. Complications

Long-term complications of diabetes can be severe and affect multiple organ systems. These include:

• Cardiovascular Disease: Diabetes significantly increases the risk of heart attack, stroke, and peripheral artery disease.
• Neuropathy: Nerve damage can cause numbness, tingling, pain, and loss of sensation, particularly in the feet and legs.
• Nephropathy: Kidney damage can lead to kidney failure.
• Retinopathy: Damage to the blood vessels in the retina can lead to vision loss and blindness.
• Foot Problems: Neuropathy and poor circulation can increase the risk of foot ulcers, infections, and amputation.
• Skin Conditions: Diabetes can increase the risk of skin infections and other skin problems.
• Hearing Impairment: Diabetes may damage the small blood vessels in the inner ear.
• Alzheimer's Disease: There is a growing body of evidence linking diabetes to an increased risk of Alzheimer's disease. Alzheimer's Disease

1. 1. Prevention

While Type 1 diabetes cannot be prevented, the risk of developing Type 2 diabetes can be reduced through lifestyle modifications. These include:

• Maintaining a Healthy Weight:
• Eating a Healthy Diet:
• Regular Physical Activity:
• Avoiding Sugary Drinks:
• Not Smoking: Smoking
• Managing Stress: Stress Management

Regular screening for diabetes is also important, especially for those with risk factors.

1. 1. Monitoring and Self-Management

Effective diabetes management requires regular monitoring of blood glucose levels and active self-management. This includes:

• Blood Glucose Monitoring: Using a blood glucose meter to check blood sugar levels several times a day.
• A1C Testing: Regular A1C tests to assess long-term blood glucose control.
• Foot Care: Daily foot inspections and proper foot hygiene.
• Eye Exams: Annual dilated eye exams.
• Kidney Function Tests: Regular tests to monitor kidney function.
• Dental Exams: Regular dental checkups.
• Education: Participating in diabetes education programs to learn about self-management strategies.

1. 1. Emerging Technologies

Several new technologies are being developed to improve diabetes management, including:

• Continuous Glucose Monitors (CGMs): Devices that continuously track blood glucose levels and provide real-time data. Continuous Glucose Monitoring
• Artificial Pancreas Systems: Systems that automatically deliver insulin based on CGM readings.
• Smart Insulin Pens: Pens that track insulin doses and provide reminders.
• Mobile Apps: Apps that help with blood glucose tracking, carbohydrate counting, and medication management.
