Diabetes: Understanding Diabetes, Causes, Symptoms, Treatment, and Types

Diabetes is a group of chronic metabolic disorders characterized by high levels of glucose (sugar) in the blood. It occurs when the body either doesn’t produce enough insulin (a hormone that regulates blood sugar) or doesn’t use insulin effectively. Here you will come to know Diabetes: Understanding Diabetes: Causes, Symptoms, Treatment, and Types

Understanding diabetes, including:

Type 1 Diabetes

Type 1 diabetes is an autoimmune condition in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body does not produce insulin. People with Type 1 diabetes need to take insulin injections or use an insulin pump to manage their blood sugar levels. This form of diabetes usually develops in childhood or early adulthood and is not preventable.

Type 2 Diabetes

Type 2 diabetes is the most common form of diabetes, accounting for the majority of cases. It typically occurs in adulthood but can also affect children and adolescents. In Type 2 diabetes, the body’s cells become resistant to insulin, and the pancreas may not produce enough insulin to compensate. This leads to elevated blood sugar levels. Lifestyle factors, such as poor diet, lack of physical activity, obesity, and genetics, contribute to the development of Type 2 diabetes. Management often involves dietary and lifestyle changes, along with oral medications or insulin therapy in some cases.

Gestational Diabetes

Gestational diabetes develops during pregnancy when the body cannot produce enough insulin to meet the increased demands due to pregnancy. It usually resolves after childbirth, but women who have had gestational diabetes are at a higher risk of developing Type 2 diabetes later in life.

Other less common types of diabetes include:

Monogenic Diabetes

This is a rare form of diabetes caused by mutations in a single gene. It often presents in childhood or young adulthood and can be mistaken for Type 1 or Type 2 diabetes. Treatment and management depend on the specific genetic mutation.

Secondary Diabetes

Some medical conditions, such as certain hormonal disorders (e.g., Cushing’s syndrome) or the use of certain medications (e.g., corticosteroids), can lead to secondary diabetes. Managing the underlying condition or adjusting medication regimens can help control blood sugar levels.

Other Specific Types

This category includes various forms of diabetes with specific causes, such as genetic syndromes, pancreatic diseases, or drug-induced diabetes. Treatment and management depend on the underlying cause.

It’s important to note that diabetes can lead to serious health complications if not well-managed. Effective management often involves lifestyle modifications, medication as prescribed by a healthcare provider, regular blood sugar monitoring, and ongoing medical care. It’s crucial for individuals with diabetes to work closely with healthcare professionals to develop a personalized diabetes management plan.

Type 3c diabetes

Type 3c diabetes also known as pancreatogenic diabetes or diabetes secondary to pancreatic disease, is a less common form of diabetes that is caused by damage or disease affecting the pancreas. Unlike the more well-known types of diabetes, such as Type 1 and Type 2 diabetes, Type 3c diabetes is characterized by pancreas-related issues leading to impaired insulin production.

Here are some key points about Type 3c diabetes

  1. Causes: This type of diabetes is primarily caused by conditions or factors that damage the pancreas, including chronic pancreatitis (inflammation of the pancreas), pancreatic surgery, cystic fibrosis, pancreatic cancer, and other diseases that affect the pancreas.
  2. Insulin Production: In Type 3c diabetes, the pancreas is unable to produce sufficient insulin due to the underlying pancreatic damage. Insulin is essential for regulating blood sugar levels by helping glucose enter cells for energy.
  3. Similarities to Type 1 and Type 2 Diabetes: Type 3c diabetes shares some similarities with both Type 1 and Type 2 diabetes. Like Type 1 diabetes, it involves insufficient insulin production, but it is not an autoimmune condition. Like Type 2 diabetes, it is often associated with adult-onset diabetes and may require insulin or other medications to manage blood sugar levels.
  4. Management: Managing Type 3c diabetes can be challenging because it often involves addressing the underlying pancreatic condition. In some cases, individuals with Type 3c diabetes may require pancreatic enzyme replacement therapy to aid digestion and insulin therapy to control blood sugar levels.
  5. Diagnosis: Diagnosing Type 3c diabetes typically involves identifying the underlying pancreatic disease or damage and conducting blood tests to measure blood glucose levels. A healthcare provider may perform imaging studies or other tests to evaluate the pancreas’s structure and function.
  6. Prognosis: The prognosis for Type 3c diabetes depends on the severity of the underlying pancreatic condition and how well it can be managed. In cases of chronic pancreatitis or pancreatic cancer, for example, the prognosis may be influenced by the stage and treatment options for the underlying disease.

Type 3c diabetes is less common than Type 1 and Type 2 diabetes, and it often requires specialized care and management. Individuals with this form of diabetes should work closely with healthcare professionals, including endocrinologists and gastroenterologists, to develop a comprehensive treatment plan tailored to their specific needs and the underlying pancreatic condition.

What Is the Global Prevalence of Diabetes?

Diabetes is a common and widespread medical condition that affects millions of people worldwide. Its prevalence has been steadily increasing over the years, primarily due to factors like obesity, sedentary lifestyles, and an aging population.

Here are some statistics on the global prevalence of diabetes

  1. Type 2 Diabetes Prevalence: Type 2 diabetes is the most common form of diabetes, and it accounts for the majority of diabetes cases. In 2019, the International Diabetes Federation (IDF) estimated that approximately 463 million adults (aged 20-79) were living with Type 2 diabetes worldwide.
  2. Type 1 Diabetes Prevalence: Type 1 diabetes is less common than Type 2 diabetes. It often develops in childhood or early adulthood. Globally, it was estimated that about 1 in 500 people had Type 1 diabetes.
  3. Gestational Diabetes: The prevalence of gestational diabetes varies by region and population, but it is a significant concern during pregnancy. Estimates suggest that between 1% and 20% of pregnancies are affected by gestational diabetes.
  4. Undiagnosed Cases: It’s important to note that many cases of diabetes, particularly Type 2 diabetes, remain undiagnosed. This means that there are likely many more individuals with diabetes who have not been formally diagnosed or treated.
  5. Global Trends: Diabetes is a global health issue, but its prevalence varies by region and is often higher in low- and middle-income countries. Some regions, such as the Middle East and North Africa, have particularly high rates of diabetes.

Factors like improved diabetes screening, increased awareness, and changes in lifestyle and diet can impact these numbers.It’s crucial to emphasize the importance of early diagnosis, proper management, and lifestyle modifications to prevent or manage diabetes effectively and reduce the risk of complications associated with the condition.

If you have concerns about diabetes or its risk factors, it is advisable to consult with a healthcare professional like Dr. Md.Mudassir Ali for guidance and screening.

Common Signs and Symptoms of Diabetes


Common signs and symptoms of diabetes can vary depending on the type of diabetes and the individual, but some of the most typical indicators include:

  1. Frequent Urination (Polyuria): Increased urination is a common early sign of diabetes. Excess glucose in the blood can lead to the kidneys trying to filter it out, resulting in increased urine production.
  2. Excessive Thirst (Polydipsia): As a consequence of frequent urination, people with diabetes often experience intense thirst to compensate for fluid loss.
  3. Unexplained Weight Loss: Despite increased hunger and food consumption, individuals with diabetes may lose weight due to the body’s inability to properly use glucose for energy.
  4. Increased Hunger (Polyphagia): Diabetes can lead to excessive hunger because the body’s cells are not getting enough glucose for energy, even if there is plenty of glucose in the bloodstream.
  5. Fatigue: Feeling tired or fatigued is a common symptom, as the body’s cells are not receiving the energy they need from glucose.
  6. Blurred Vision: High blood sugar levels can cause the lens in the eye to swell, affecting vision and leading to blurred or distorted vision.
  7. Slow Wound Healing: Diabetes can impair the body’s ability to heal wounds and injuries. Sores, cuts, and bruises may take longer to heal than usual.
  8. Frequent Infections: High blood sugar can weaken the immune system, making individuals with diabetes more susceptible to infections, such as urinary tract infections, skin infections, and yeast infections.
  9. Tingling or Numbness: Some people with diabetes may experience tingling, numbness, or pain in their hands or feet, a condition known as diabetic neuropathy.
  10. Dry Skin and Itching: Diabetes can cause skin dryness and itching, often due to poor circulation and nerve damage.
  11. Yeast Infections: Women with diabetes may be more prone to yeast infections, particularly vaginal yeast infections.
  12. Thirst and Dry Mouth: Excessive thirst and a dry mouth can result from dehydration due to frequent urination and high blood sugar.

It’s important to note that while these symptoms are common in diabetes, they may not always be present, or they may vary in severity. Additionally, some individuals may not experience noticeable symptoms until their diabetes is more advanced.

If you or someone you know is experiencing any of these symptoms, especially if they persist or worsen, it’s essential to seek medical attention for proper evaluation and diagnosis. Early diagnosis and management of diabetes are crucial for preventing complications and maintaining overall health.

Complications Associated with Diabetes

Diabetes is a chronic condition that can lead to various complications when not properly managed. These complications can affect different parts of the body and have the potential to be serious or even life-threatening. Here are some of the common complications associated with diabetes:

  1. Cardiovascular Complications:
    • Heart Disease: People with diabetes have an increased risk of heart disease, including coronary artery disease, heart attacks, and stroke.
    • High Blood Pressure: Diabetes can contribute to high blood pressure, which further raises the risk of heart-related problems.
  2. Nerve Damage (Neuropathy):
    • Peripheral Neuropathy: Diabetes can damage the nerves in the extremities, leading to numbness, tingling, and pain, often in the feet and hands.
    • Autonomic Neuropathy: This can affect the nerves controlling internal organs, leading to digestive issues, bladder problems, and sexual dysfunction.
  3. Eye Complications (Retinopathy):
    • Diabetic Retinopathy: High blood sugar can damage the blood vessels in the retina, potentially leading to vision problems and even blindness if left untreated.
  4. Kidney Disease (Nephropathy):
    • Diabetic Nephropathy: Diabetes can damage the small blood vessels in the kidneys, eventually leading to kidney failure if not managed.
  5. Foot Complications:
    • Foot Ulcers: Nerve damage and poor blood flow in the feet can lead to ulcers, infections, and, in severe cases, amputation.
    • Charcot’s Foot: A condition where the bones in the foot weaken and collapse, often requiring surgery.
  6. Skin Complications:
    • Bacterial and Fungal Infections: High blood sugar levels can create a conducive environment for infections, particularly in the skin.
    • Diabetic Dermopathy: Skin changes, including patches and discoloration, are common in diabetes.
  7. Gastroparesis: Diabetes can affect the nerves that control the stomach, leading to delayed emptying and digestive problems.
  8. Mental Health Issues: Living with diabetes can be emotionally challenging and may contribute to stress, depression, and anxiety.
  9. Pregnancy Complications: Gestational diabetes can lead to complications during pregnancy, such as high blood pressure and the risk of delivering a large baby.
  10. Hearing Loss: There is evidence to suggest that diabetes may be associated with an increased risk of hearing problems.

It’s essential for individuals with diabetes to work closely with healthcare professionals to manage their condition effectively. Proper blood sugar control, a healthy lifestyle, regular monitoring, and adherence to treatment plans can help reduce the risk of complications or delay their onset. Early detection and intervention are also crucial in addressing diabetes-related complications when they do occur.

How is Diabetes Diagnosed and Detected?


Diabetes is diagnosed and detected through various tests and assessments that measure blood sugar levels. The primary methods for diagnosing diabetes include:

  1. Fasting Blood Sugar Test: This test involves measuring your blood sugar level after an overnight fast. A fasting blood sugar level of 126 milligrams per deciliter (mg/dL) or higher on two separate occasions typically indicates diabetes.
  2. Oral Glucose Tolerance Test (OGTT): This test involves fasting overnight and then drinking a sugary solution. Blood sugar levels are measured at intervals over the next few hours. A blood sugar level of 200 mg/dL or higher after 2 hours is a sign of diabetes.
  3. Hemoglobin A1c Test: This test provides an estimate of your average blood sugar levels over the past 2-3 months. An A1c level of 6.5% or higher is generally considered diagnostic of diabetes.
  4. Random Blood Sugar Test: This test measures blood sugar levels at any time, regardless of when you last ate. A blood sugar level of 200 mg/dL or higher, along with symptoms of diabetes, may indicate the condition.
  5. Glycated Albumin (GA) Test: This test measures the percentage of glycated albumin in the blood, providing a shorter-term reflection of blood sugar control compared to the A1c test.
  6. Fructosamine Test: Like the A1c test, this test provides an average blood sugar level over the previous 2-3 weeks by measuring the levels of fructosamine, a protein that binds to glucose in the blood.
  7. Urine Tests: Though less common today, urine tests may be used to detect glucose or ketones in the urine. Elevated glucose in the urine may indicate high blood sugar levels, often associated with diabetes.
  8. Autoantibody Tests (Type 1 Diabetes): For individuals suspected of having Type 1 diabetes, autoantibody tests may be conducted to detect the presence of specific antibodies related to autoimmune destruction of insulin-producing cells in the pancreas.
  9. C-peptide Test: This blood test measures the level of C-peptide, a byproduct of insulin production. It can help differentiate between Type 1 and Type 2 diabetes, as well as assess the body’s ability to produce insulin.
  10. Continuous Glucose Monitoring (CGM): CGM systems involve wearing a device that continuously measures glucose levels in the interstitial fluid. While it’s more commonly used for diabetes management, it can also aid in diagnosis in some cases.

The specific tests used and diagnostic criteria may vary depending on the healthcare provider, region, and circumstances. If you have symptoms of diabetes or risk factors for the condition, it’s important to consult a healthcare professional for proper testing and evaluation. Early diagnosis and appropriate management are critical in controlling diabetes and preventing complications.
