Diabetes in Nigeria
Updated 09-01-2024
Diabetes is a growing public health concern in Nigeria, with both type 1 and type 2 diabetes being common. Lifestyle factors, genetic predisposition, and a lack of healthcare access all contribute to its rising prevalence. In this article i will explain everything about diabetes
In today's world, there's a big health problem called Diabetes Mellitus. It is a complicated issue that affects many people around this world. It is all about having strange levels of sugar in your blood and it causes problems for people, their families, and healthcare systems. As the prevalence of diabetes continues to rise, understanding it various forms, risk factors, symptoms, and potential complications becomes paramount. In this article,we will talk about everything about of Diabetes Mellitus, exploring its impact on public health and the importance of early detection, prevention, and effective management strategies to mitigate its detrimental effects.
TYPES OF DIABETES MELLITUS:
Diabetes Mellitus is a diverse group of metabolic disorders, and understanding its different types is essential for targeted management and care. Each type of diabetes presents distinct characteristics, causes, and management approaches. Let's delve deeper into the four main types of Diabetes Mellitus:
Type 1 Diabetes:
Type 1 diabetes, also known as insulin-dependent diabetes or juvenile diabetes, is an autoimmune condition where the body's immune system attacks and destroys the insulin-producing beta cells in the pancreas. As a result, little to no insulin is produced, leading to uncontrolled glucose levels in the bloodstream. Type 1 diabetes typically manifests in childhood or adolescence, although it can occur at any age. The exact cause of type 1 diabetes remains unknown, but it is believed to be a combination of genetic susceptibility and environmental triggers, such as viral infections. Individuals with type 1 diabetes require lifelong insulin therapy to manage their blood sugar levels, as the pancreas cannot produce enough insulin on its own.
Type 2 Diabetes:
Type 2 diabetes, also referred to as non-insulin-dependent diabetes, is the most prevalent form of diabetes worldwide. It occurs when the body's cells become resistant to insulin, and the pancreas cannot produce enough insulin to overcome this resistance. Type 2 diabetes is closely associated with lifestyle factors, including obesity, physical inactivity, and poor dietary choices. Excess body fat particularly around the abdomen leads to the release of chemicals that interfere with insulin's action, contributing to insulin resistance. This type of diabetes typically develops in adulthood, but an alarming trend of type 2 diabetes cases among children and adolescents has been observed in recent years, mainly due to rising obesity rates. Management of type 2 diabetes includes lifestyle modifications, such as weight loss, regular exercise, and dietary changes, along with oral medications or insulin therapy, if necessary.
Prediabetes:
Prediabetes is a precursor to type 2 diabetes, where blood sugar levels are higher than normal but not yet in the diabetic range. It is a critical warning sign that individuals are at high risk of developing type 2 diabetes if preventive measures are not taken. The causes of prediabetes closely mirror those of type 2 diabetes, with lifestyle factors playing a significant role. Being overweight, physically inactive, and having an unhealthy diet are common risk factors. Identifying prediabetes early allows for timely interventions, such as lifestyle changes and weight loss, to prevent or delay the onset of type 2 diabetes.
Gestational Diabetes:
Gestational diabetes occurs during pregnancy and usually develops around the second trimester. Hormones produced by the placenta interfere with insulin's action, resulting in insulin resistance. The pancreas attempts to produce extra insulin to control blood sugar levels during pregnancy. While most women can manage gestational diabetes through dietary adjustments and physical activity, some may require insulin therapy. Gestational diabetes poses risks to both the mother and the baby. It can lead to complications during pregnancy and delivery, and babies born to mothers with gestational diabetes may be larger than usual, increasing the risk of birth injuries. Additionally, both the mother and the child have an increased risk of developing type 2 diabetes later in life, underscoring the importance of postnatal monitoring and lifestyle modifications.
CAUSES OF DIABETES MELLITUS
Type 1 Diabetes: Type 1 diabetes is an autoimmune condition where the immune system mistakenly attacks and destroys insulin-producing beta cells in the pancreas. It is likely caused by a combination of genetic susceptibility and environmental triggers, such as viral infections.
Type 2 Diabetes: Type 2 diabetes occurs when the body's cells become resistant to insulin, and the pancreas doesn't produce enough insulin to compensate. Family history and genetics contribute, but lifestyle factors play a significant role. Obesity, physical inactivity, and unhealthy diets are key risk factors.
Prediabetes: Prediabetes is characterized by higher-than-normal blood sugar levels and is mainly linked to excess body weight, lack of physical activity, and poor dietary choices.
Gestational Diabetes:Gestational diabetes is related to hormonal changes during pregnancy, leading to insulin resistance. While the exact causes are not fully understood, hormonal and genetic factors are believed to be involved. Women who are overweight or have a family history of diabetes are at higher risk.
SYMPTOMS OF DIABETES MELLITUS:
Common Symptoms of Type 1 and Type 2 Diabetes:
- Increased Thirst (Polydipsia)
- Frequent Urination (Polyuria)
- Extreme Hunger (Polyphagia)
- Unexplained Weight Loss
- Fatigue
- Blurred Vision
- Slow-Healing Sores and Infections
Additional Symptoms of Type 1 Diabetes:
- Sudden Onset
- Ketones in Urine (Ketosis)

TEST AND DIAGNOSIS OF DIABETES MELLITUS:
Timely and accurate diagnosis is crucial for effective diabetes management and prevention of complications. Key tests for different types of diabetes and prediabetes include:
1. Glycated Hemoglobin (A1C) Test: Measures average blood sugar levels over two to three months. A result of 6.5% or higher confirms diabetes, while 5.7% to 6.4% indicates prediabetes.
2. Random Blood Sugar Test: Measures blood sugar at any time. A level of 200 mg/dL (11.1 mmol/L) or higher suggests diabetes.
3. Fasting Blood Sugar Test: Measures blood sugar after an overnight fast. A level above 126 mg/dL (7 mmol/L) on two separate tests confirms diabetes, while 100-125 mg/dL (5.6-6.9 mmol/L) indicates prediabetes.
4. Oral Glucose Tolerance Test: Measures blood sugar after fasting and consuming a sugary liquid. A reading above 200 mg/dL (11.1 mmol/L) after two hours indicates diabetes, while 140-199 mg/dL (7.8-11.0 mmol/L) indicates prediabetes.
5. Ketones in Urine Test: Detects ketones in urine, important for suspected type 1 diabetes.
6. Autoantibody Test: Identifies autoantibodies associated with type 1 diabetes.
Tests for Gestational Diabetes:
• Glucose Challenge Test: Measures blood sugar after drinking glucose solution. Elevated levels may require further testing.
• Glucose Tolerance Test: Measures blood sugar levels after fasting and consuming a glucose solution. Abnormal readings suggest gestational diabetes.
Regular screenings, especially for those with risk factors, promote early detection and help prevent complications associated with diabetes mellitus.
