In today's world, unhealthy eating habits and sedentary lifestyles have become increasingly common. Unfortunately, these changes are driving a surge in lifestyle-related health conditions, particularly diabetes mellitus, which is affecting millions of lives worldwide. Managing this complex and pervasive condition requires specialised knowledge and skills that could provide early interventions. 

For medical professionals aiming to enhance their expertise in diabetes care, a Fellowship in Diabetes Mellitus offers an invaluable opportunity to gain advanced knowledge and skills. This diabetes mellitus fellowship course provides an in-depth understanding of diabetes management, well-equipping medical professionals to address the growing demand for specialised care.

By pursuing this fellowship, medical professionals not only gain knowledge but also enhance the quality of diabetes care and make a significant impact on public health.

Understanding Diabetes Mellitus

Diabetes mellitus is a chronic metabolic disorder marked by elevated glucose levels in the blood. It occurs when the body either does not produce enough insulin or cannot use the insulin produced effectively.

Insulin is a hormone produced by the pancreas responsible for regulating blood glucose levels. Due to the dysfunction of the insulin production, it results in elevated blood glucose levels, which can lead to a range of health complications if not properly managed.

Types of Diabetes Mellitus

Diabetes mellitus is classified into several types.

• Prediabetes is a condition where blood glucose levels are higher than the normal range but not high enough to be diagnosed as diabetes mellitus. It develops gradually and is usually silent, with few or no symptoms. Often detected during routine blood tests. A few causes are obesity, poor diet, lack of physical activity, and family history of diabetes.
• Type 1 Diabetes Mellitus is an autoimmune disorder in which the immune system attacks and destroys the pancreas's insulin-producing beta cells. It typically develops in childhood or adolescence, but it can occur at any age.
• Type 2 Diabetes Mellitus mainly involves insulin resistance, where the body's cells fail to respond appropriately to insulin. Obesity, sedentary lifestyle, and genetic factors are a few causes. This type is more common in adults but is increasingly being diagnosed in younger populations, including children and adolescents.
• Gestational Diabetes occurs during pregnancy. The cause of gestational diabetes is hormonal changes that affect insulin's ability to regulate blood glucose levels. It typically develops in the second or third trimester and usually resolves after childbirth. However, it increases the risk of developing Type 2 diabetes mellitus later on in life.
• Other Specific Types of diabetes mellitus are present, but they are less common forms, such as monogenic diabetes.

Symptoms of Diabetes Mellitus

Common symptoms of diabetes mellitus include Frequent urination, Excessive thirst, Unexplained weight loss, Extreme hunger, Fatigue, Blurred vision and Slow-healing sores or frequent infections.

In Type 1 diabetes mellitus, symptoms may develop quickly, often over a few weeks. In Type 2 diabetes mellitus, symptoms may be mild and develop gradually, sometimes going unnoticed for years.

Diagnosis of Diabetes Mellitus

Physicians usually recommend blood tests to confirm the diagnosis. These blood tests measure blood glucose levels in the body. Common tests include:

• Fasting Blood Glucose Test: This test measures blood glucose after an overnight fast.
• Oral Glucose Tolerance Test (OGTT): The OGTT measures blood glucose before and after drinking a glucose-rich beverage.
• Haemoglobin A1c (HbA1c)Test: This test provides an estimate of the average blood glucose levels in the body over the past two to three months.

Blood Glucose Levels: Normal and Abnormal Ranges

Normal Blood Glucose Levels (Non-Diabetic):

• Fasting plasma glucose: < 100 mg/dL
• Postprandial (2 hours after meal): < 140 mg/dL
• HbA1c: < 5.7%

Prediabetes:

• Fasting plasma glucose: 100–125 mg/dL
• Postprandial (2 hours): 140–199 mg/dL
• HbA1c: 5.7%–6.4%

Diabetes (Abnormal Levels):

• Fasting plasma glucose: ≥ 126 mg/dL
• Postprandial (2 hours): ≥ 200 mg/dL
• HbA1c: ≥ 6.5%

Complications of Diabetes Mellitus

If diabetes remains uncontrolled, it can lead to serious complications. The three major ones include neuropathy (nerve damage causing pain, tingling, or numbness in the feet), nephropathy (kidney damage that may progress to failure), and retinopathy (damage to the retina leading to vision loss or blindness). Diabetes can also increase the risk of heart disease, foot ulcers, and skin infections, making proper management essential.

Management and Treatment of Diabetes Mellitus

The primary objectives for managing diabetes mellitus are to maintain blood glucose levels within the normal range, prevent complications, and overall enhance quality of life. The management of diabetes mellitus includes:

1. Lifestyle Changes:

• A balanced diet rich in fruits, vegetables, whole grains, lean proteins, and healthy fats is crucial. One should continue to monitor carbohydrate intake, as it is crucial for maintaining blood glucose control.
• Engaging in regular physical activity enhances insulin sensitivity and reduces blood glucose levels.
• Keeping a healthy weight can lower the risk of complications and enhance overall diabetes management. 

2. Medications:

• Insulin: Insulin therapy is crucial for managing Type 1 diabetes mellitus and may also be necessary for some individuals with Type 2 diabetes mellitus. Insulin can be administered through injections or via an insulin pump, providing options for effective diabetes management.
• Oral Medications: Oral medications for managing Type 2 diabetes improve insulin sensitivity, decrease glucose production in the liver, or stimulate insulin release from the pancreas.
• Other Injectable Medications: Some non-insulin injectables help regulate blood glucose levels by mimicking the action of certain hormones involved in glucose metabolism.

3. Monitoring:

• Self-Monitoring of Blood Glucose (SMBG): Regular blood glucose testing, using a glucose meter or a continuous glucose monitor (CGM), helps individuals track their blood glucose levels and adjust their treatment as needed.
• Regular Check-ups: Regular visits to healthcare providers for monitoring and adjusting treatment plans are essential for optimal diabetes management.

Prevention of Diabetes Mellitus

Adopting lifestyle changes can often prevent or delay the onset of Type 2 and gestational diabetes. Several preventive measures are: 

• Healthy Diet: Keep the emphasis on a diet rich in fibre, whole grains, and lean proteins while limiting glucose and refined carbohydrates.
• Exercise and Weight Management: Engaging in at least 150 minutes of moderate-intensity physical activity each week is necessary to maintain a healthy weight.
• Regular Monitoring: Have regular blood glucose screenings to detect any changes early in individuals with prediabetes or at high risk for diabetes mellitus.

However, type 1 diabetes cannot be prevented, as it is an autoimmune condition. In contrast to type 2 diabetes, lifestyle changes have no role in preventing its onset.

Key Components of the Fellowship in Diabetes Mellitus

The fellowship in diabetes mellitus is an ideal pathway for medical professionals who wish to continue their learning journey while working. The key components of the fellowship in diabetes mellitus are:

• Clinical Training: Participants gain hands-on experience in treating various forms of diabetes mellitus and managing diabetes-related complications.
• Patient Education and Advocacy: Participants learn how to communicate with patients effectively. This includes educating patients about diet, exercise, medication adherence, and monitoring blood glucose levels.
• Advanced Technologies: The fellowship also covers the use of advanced technologies in diabetes care, such as continuous glucose monitoring (CGM) systems, which enable medical professionals to integrate these technologies into patient care to improve treatment outcomes.
• Interdisciplinary Collaboration: Diabetes care often requires a multidisciplinary approach to develop a holistic approach to diabetes management. Participants work closely with other healthcare professionals, such as dietitians and nurses, to provide comprehensive care to patients.
