Diabetes
What is Diabetes?
Diabetes is a chronic metabolic condition marked by elevated blood glucose levels. It happens when the body either does not create enough insulin or does not utilise insulin adequately. Insulin is a hormone generated by the pancreas that aids in blood sugar regulation.
Definition of diabetes
Diabetes is a condition in which the body's ability to regulate blood glucose is impaired. The excess glucose in the blood can lead to various health complications if not properly managed.
Prevalence and global impact
- Diabetes is a global health concern, affecting millions of people worldwide.
- According to the International Diabetes Federation, around 463 million individuals in 2019 had diabetes, with this figure expected to climb to 700 million by 2045.
Role of insulin in diabetes
- Insulin plays a crucial role in diabetes management by helping transport glucose from the bloodstream into cells for energy production.
- In individuals with diabetes, there is either insufficient insulin production (Type 1 diabetes) or insulin resistance (Type 2 diabetes), leading to elevated blood sugar levels.

Types of Diabetes
There are two types of Diabetes -
- Type 1 Diabetes
- Type 2 Diabetes
A. Type 1 Diabetes
Causes and risk factors
- Type 1 diabetes is an autoimmune disease where the immune system mistakenly attacks the insulin-producing cells in the pancreas.
- Genetic predisposition and environmental factors, such as viral infections, may contribute to its development.
Symptoms and diagnosis
- Rapid onset of symptoms, often in childhood or adolescence.
- Common symptoms include frequent urination, excessive thirst, unexplained weight loss, fatigue, and blurry vision.
- Diagnosis is made through blood tests that measure blood glucose levels and detect autoantibodies.
Treatment and management
- Individuals with Type 1 diabetes require lifelong insulin therapy.
- Insulin is administered through injections or an insulin pump to maintain normal blood sugar levels.
- Close monitoring of blood glucose levels, regular exercise, and a healthy diet are essential components of management.
B. Type 2 Diabetes
Causes and risk factors
- Type 2 diabetes is primarily influenced by lifestyle factors, including poor diet, sedentary lifestyle, and obesity.
- Genetic factors and family history also play a role in its development.
Symptoms and diagnosis
- Symptoms of Type 2 diabetes may develop gradually and include increased thirst, frequent urination, fatigue, and slow wound healing.
- Diagnosis involves blood tests to measure fasting glucose levels and an oral glucose tolerance test (OGTT).
Treatment and management
- Lifestyle modifications, such as adopting a healthy diet and increasing physical activity, are crucial in managing Type 2 diabetes.
- Oral medications may be prescribed to help control blood sugar levels.
- In some cases, insulin therapy may be required if other treatments are ineffective.

Gestational Diabetes
Occurrence during pregnancy
- Gestational diabetes develops during pregnancy and normally goes away once the baby is born.
- Hormonal changes during pregnancy can lead to insulin resistance, resulting in elevated blood sugar levels.
Causes, risk factors, and diagnosis
1. The specific reason is unknown, however hormonal and genetic factors may play a role.
2. Risk factors include maternal age, obesity, a family history of diabetes, and a history of gestational diabetes in previous pregnancies.
3. Diagnosis is typically made through a glucose challenge test and, if necessary, a glucose tolerance test.
Treatment and management
1. Lifestyle modifications, including a balanced diet and regular exercise, are key to managing gestational diabetes.
2. Some women may require insulin therapy to maintain blood sugar levels within the target range.

Common Symptoms of Diabetes
Recognizing the symptoms of diabetes is crucial for early detection and timely intervention. Common symptoms include:
1. Frequent urination: Increased need to urinate, especially at night.
2. Excessive thirst and hunger: Feeling constantly thirsty and experiencing unexplained hunger.
3. Unexplained weight loss or gain: Sudden weight loss despite increased appetite or unexplained weight gain.
4. Fatigue and irritability: Feeling tired, lacking energy, and experiencing mood swings.
5. Blurry vision: Impaired vision or difficulty focusing.
6. Slow-healing wounds and infections: Cuts and sores take longer to heal, and infections may occur frequently.
2. Excessive thirst and hunger: Feeling constantly thirsty and experiencing unexplained hunger.
3. Unexplained weight loss or gain: Sudden weight loss despite increased appetite or unexplained weight gain.
4. Fatigue and irritability: Feeling tired, lacking energy, and experiencing mood swings.
5. Blurry vision: Impaired vision or difficulty focusing.
6. Slow-healing wounds and infections: Cuts and sores take longer to heal, and infections may occur frequently.

Risk Factors for Diabetes
Certain factors increase the risk of developing diabetes, including:
1. Genetic predisposition: Having a family history of diabetes increases the likelihood of developing the condition.
2. Sedentary lifestyle: Lack of physical activity and a sedentary lifestyle contribute to the risk of diabetes.
3. Poor dietary habits: A diet high in processed foods, sugary drinks, and unhealthy fats increases the risk.
4. Obesity and overweight: Excess body weight puts strain on insulin production and function.
5. Age and ethnicity: The risk of diabetes increases with age, and certain ethnic groups, such as African Americans, Hispanics, and Asians, have a higher susceptibility.

Diagnosis and Screening
Early diagnosis of diabetes is crucial for effective management. The following diagnostic tests and screening recommendations are commonly used:
1. Blood glucose tests: Fasting plasma glucose (FPG) and random plasma glucose (RPG) tests measure blood glucose levels.
2. Glycated hemoglobin (A1C) test: This test provides an average blood sugar level over the past 2-3 months.
3. Oral glucose tolerance test (OGTT): A glucose solution is consumed, and blood sugar levels are measured periodically.
4. Regular screening recommendations: Individuals with risk factors should undergo regular screening tests to detect diabetes early.

Treatment
Diabetes treatment aims to keep blood sugar levels within the target range and minimize the risk of complications.
A. Medication
1. Insulin therapy
- Type 1 diabetes and some cases of Type 2 diabetes may require insulin injections to regulate blood sugar levels effectively.
- Various types of insulin are available, including rapid-acting, short-acting, intermediate-acting, and long-acting insulin.
2. Oral medications
- Type 2 diabetes is often managed with oral medications that help control blood sugar levels.
- These medications work in different ways, such as stimulating insulin production or improving insulin sensitivity.
B. Lifestyle Modifications
1. Healthy diet and meal planning - Following a balanced diet rich in whole grains, fruits, vegetables, proteins, and healthy fats. Monitoring carbohydrate intake and practicing portion control.
2. Regular physical activity - Engaging in regular exercise, such as walking, jogging, swimming, or cycling, to improve insulin sensitivity and manage weight.
3. Blood sugar monitoring - Regularly checking blood sugar levels using a glucometer to maintain optimal control.
4. Stress management technique - Implementing stress-reducing activities like meditation, deep breathing, or engaging in hobbies.
5. Importance of sleep - Prioritizing sufficient sleep to regulate hormone levels and improve overall well-being.

Long-Term Complications of Diabetes
Poorly controlled diabetes can lead to several long-term complications affecting various organ systems. These include:
1. Cardiovascular diseases: Increased risk of heart disease, heart attacks, stroke, and peripheral artery disease.
2. Nerve damage (neuropathy): Damage to nerves, leading to tingling, numbness, pain, and impaired sensation in the extremities.
3. Kidney damage (nephropathy): Diabetic nephropathy can progress to kidney failure and the need for dialysis or kidney transplantation.
4. Eye complications (retinopathy): Damage to blood vessels in the retina, leading to vision impairment and blindness if left untreated.
5. Foot problems: Nerve damage and poor blood circulation increase the risk of foot ulcers, infections, and amputation.
6. Skin conditions: Diabetes can cause skin problems, such as bacterial and fungal infections, dry skin, and slow wound healing.
