Diabetes
People of all ages are susceptible to the prevalent disease known as diabetes. Diabetes comes in a variety of shapes. The most typical kind is type 2. You may control the illness to lead a healthy life and avoid consequences by using a variety of therapeutic methods.
What is diabetes?
Diabetes is a chronic medical condition characterized by high levels of glucose (sugar) in the blood. This occurs when the body is unable to produce or effectively use insulin, a hormone that regulates blood sugar levels.
What are the types of diabetes?
There are two main types of diabetes: type 1 and type 2 diabetes. Additionally, there is a third type called gestational diabetes that occurs during pregnancy.
Type 1 diabetes:
Prediabetes:
Prediabetes is a condition in which blood sugar levels are higher than normal but not high enough to be classified as type 2 diabetes. It is considered a warning sign that a person may be at risk for developing diabetes if they don't make lifestyle changes.
Prediabetes is typically diagnosed when fasting blood sugar levels are between 100 and 125 mg/dL, or when A1C levels are between 5.7 and 6.4 percent. A1C is a blood test that measures average blood sugar levels over the past 2-3 months.
Type 2 diabetes:
Type 2 diabetes occurs when the body becomes resistant to insulin, or when the pancreas does not produce enough insulin to meet the body's needs. This type of diabetes is often associated with lifestyle factors such as obesity, physical inactivity, and poor diet. Type 2 diabetes is usually diagnosed in adulthood, although it is becoming more common in younger people.
Gestational diabetes:
Other types of diabetes include:
Type 3c diabetes:
Type 3c diabetes, also known as pancreatogenic diabetes, is a rare form of diabetes that occurs as a result of damage to the pancreas. This damage can be caused by conditions such as pancreatitis, pancreatic cancer, or surgical removal of the pancreas.
Unlike type 1 and type 2 diabetes, which are primarily caused by autoimmune dysfunction or insulin resistance, respectively, type 3c diabetes is caused by a deficiency of the hormones produced by the pancreas, including insulin.
Symptoms of type 3c diabetes are similar to those of type 1 and type 2 diabetes and can include increased thirst and hunger, frequent urination, blurred vision, fatigue, slow wound healing, and weight loss.
Diagnosis of type 3c diabetes involves testing for both blood sugar levels and pancreatic function. Treatment may involve insulin therapy, as well as management of any underlying pancreatic disorders.
Type 3c diabetes is less common than type 1 or type 2 diabetes, and it is often misdiagnosed or undiagnosed. It is important for people who have had pancreatitis or other pancreatic disorders to be aware of the risk of developing type 3c diabetes and to be vigilant for symptoms.
Latent autoimmune diabetes in adults (LADA):
Latent autoimmune diabetes in adults (LADA) is a type of diabetes that shares features of both type 1 and type 2 diabetes. It is also sometimes referred to as type 1.5 diabetes.
LADA is caused by an autoimmune reaction that destroys the insulin-producing cells (beta cells) in the pancreas, similar to type 1 diabetes. However, unlike type 1 diabetes, which typically develops in childhood or adolescence, LADA usually develops in adulthood.
Symptoms of LADA are similar to those of type 1 and type 2 diabetes and can include increased thirst and hunger, frequent urination, blurred vision, fatigue, slow wound healing, and weight loss. LADA is often misdiagnosed as type 2 diabetes, as it can initially present with features of insulin resistance and may not require insulin therapy in the early stages.
Diagnosis of LADA involves testing for the presence of autoantibodies that are associated with autoimmune diabetes. Treatment may involve lifestyle changes such as a healthy diet and regular exercise, as well as medication to help control blood sugar levels. In later stages, insulin therapy may be necessary.
LADA is a relatively rare form of diabetes, accounting for an estimated 5-10% of all cases of diabetes. It is important for people with LADA to receive a proper diagnosis and appropriate treatment, as untreated or undertreated LADA can lead to complications such as heart disease, kidney damage, nerve damage, and blindness.
Maturity-onset diabetes of the young (MODY):
Maturity-onset diabetes of the young (MODY) is a type of diabetes that is caused by a genetic mutation that affects the body's ability to produce insulin. It is a rare form of diabetes, accounting for less than 5% of all diabetes cases.
MODY is typically diagnosed in children, adolescents, or young adults who have a family history of diabetes. The age of onset can vary, but it is usually before the age of 25.
Symptoms of MODY are similar to those of other types of diabetes and can include increased thirst and hunger, frequent urination, blurred vision, fatigue, slow wound healing, and weight loss.
Diagnosis of MODY involves genetic testing to identify the specific genetic mutation that is causing the condition. Treatment may involve lifestyle changes such as a healthy diet and regular exercise, as well as medication to help control blood sugar levels.
MODY is often misdiagnosed as type 1 or type 2 diabetes, as it can have features of both conditions. However, unlike type 1 and type 2 diabetes, which are primarily caused by autoimmune dysfunction or insulin resistance, respectively, MODY is caused by a specific genetic mutation.
There are several different types of MODY, each caused by a different genetic mutation. Treatment and management may vary depending on the specific type of MODY and the severity of the condition. It is important for people with MODY to receive a proper diagnosis and appropriate treatment to prevent or manage complications such as heart disease, kidney damage, nerve damage, and blindness.
Brittle diabetes:
Brittle diabetes is a term used to describe a type of diabetes that is very difficult to manage and control, with wide and frequent fluctuations in blood sugar levels. It is also known as labile diabetes or unstable diabetes.
People with brittle diabetes experience frequent and unpredictable episodes of low blood sugar (hypoglycemia) and high blood sugar (hyperglycemia), which can lead to serious health complications such as seizures, unconsciousness, and even death.
Brittle diabetes can occur in people with both type 1 and type 2 diabetes, but it is more commonly associated with type 1 diabetes. The exact cause of brittle diabetes is not fully understood, but it is believed to be related to a combination of factors such as insulin resistance, hormonal imbalances, and emotional or psychological stress.
Treatment for brittle diabetes involves close monitoring of blood sugar levels, frequent adjustments to insulin doses and other diabetes medications, and lifestyle changes such as a healthy diet and regular exercise. People with brittle diabetes may also benefit from psychological counseling or stress management techniques to help them cope with the emotional and psychological stress associated with the condition.
It is important for people with brittle diabetes to work closely with their healthcare providers to develop an individualized treatment plan that can help them manage the condition and prevent complications.
How common is diabetes?
Diabetes is a common chronic condition worldwide. According to the International Diabetes Federation, in 2021, an estimated 537 million adults (20-79 years) were living with diabetes globally. That is about 1 in 11 adults.
Type 2 diabetes is the most common form of diabetes, accounting for about 90% of all cases. Type 1 diabetes, gestational diabetes, and other less common types of diabetes make up the remaining 10%.
The prevalence of diabetes varies by region and country, with the highest numbers in low- and middle-income countries. Diabetes is also more common among certain ethnic and racial groups, such as South Asians, Hispanics, and African Americans.
The number of people with diabetes is expected to continue to rise in the coming years, due to factors such as aging populations, urbanization, and changes in lifestyle and diet. However, with early detection and appropriate management, people with diabetes can lead healthy and productive lives.
What are the symptoms of diabetes?
The symptoms of diabetes can vary depending on the type of diabetes and how long the person has had the condition. Some people with diabetes may not have any symptoms at all, especially in the early stages of the disease. However, the most common symptoms of diabetes include:

Frequent urination: When blood sugar levels are high, the kidneys work harder to filter and absorb excess sugar. This can cause a person to urinate more frequently, including waking up frequently during the night to use the bathroom.
Increased thirst: Because a person with diabetes is urinating more frequently, they may become dehydrated, leading to feelings of thirst.
Unexplained weight loss: If the body is unable to use glucose for energy, it may start to break down fat and muscle for fuel, leading to weight loss.
Increased hunger: Because the body is not able to use glucose for energy, it may feel like it needs more food to fuel itself.
Fatigue: Without enough glucose to fuel the body's cells, a person with diabetes may feel tired and lethargic.
Blurred vision: High blood sugar levels can cause fluid to be pulled from the lenses of the eyes, leading to blurry vision.
Slow healing of cuts or sores: High blood sugar levels can affect the body's ability to heal properly, leading to slow healing of cuts, sores, or other wounds.
Numbness or tingling in the hands or feet: High blood sugar levels can cause nerve damage, leading to numbness or tingling in the hands or feet.
What are the complications of diabetes?
Diabetes can cause a wide range of complications that affect various parts of the body. Some of the common complications of diabetes include:

Acute diabetes complications
Diabetic ketoacidosis (DKA):
Hyperosmolar hyperglycemic state (HHS):
Hypoglycemia:
Hyperglycemia:
Infections:
It is important for people with diabetes to monitor their blood sugar levels regularly and to seek medical attention immediately if they experience any of these acute complications. Early treatment can prevent these conditions from becoming life-threatening.
Long-term diabetes complications
Long-term complications of diabetes can develop over several years and are often a result of poorly controlled blood glucose levels. Some of the long-term complications of diabetes include:
Cardiovascular disease:
Diabetes increases the risk of developing cardiovascular diseases such as heart attack, stroke, and peripheral artery disease.
Nerve damage (neuropathy):
Long-term high blood glucose levels can damage the nerves in the body, leading to pain, numbness, and tingling in the hands and feet.
Kidney damage (nephropathy):
Diabetes can damage the kidneys and cause them to function improperly, which can lead to kidney failure.
Eye damage (retinopathy):
Diabetes can damage the blood vessels in the eyes and cause vision problems, including blindness.
Foot damage:
Nerve damage and poor blood flow can cause foot problems, including ulcers, infections, and in severe cases, amputations.
Skin conditions:
Diabetes can cause skin conditions such as bacterial and fungal infections, as well as diabetic dermopathy, which causes brown patches on the skin.
Dental problems:
People with diabetes are at a higher risk of developing gum disease, tooth decay, and other dental problems.
Gastroparesis:
This is a condition where the muscles in the stomach do not work properly, leading to delayed stomach emptying, nausea, and vomiting.
Erectile dysfunction:
Diabetes can damage blood vessels and nerves that supply blood to the penis, causing erectile dysfunction.
Cognitive decline:
There is some evidence to suggest that long-term poorly controlled diabetes may increase the risk of cognitive decline and dementia.
It's important for people with diabetes to manage their blood glucose levels, blood pressure, and cholesterol levels to help prevent or delay the onset of these long-term complications. Regular monitoring, medications, and lifestyle modifications can help control
How is diabetes diagnosed?
Diabetes can be diagnosed through a variety of tests and procedures. The most common tests used to diagnose diabetes include:
Fasting Plasma Glucose Test (FPG):
This test measures your blood glucose levels after an overnight fast of at least 8 hours. A result of 126 mg/dL or higher indicates diabetes.
Hemoglobin A1c Test (HbA1c):
This test measures your average blood glucose levels over the past 2-3 months. A result of 6.5% or higher indicates diabetes.
Oral Glucose Tolerance Test (OGTT):
This test involves drinking a glucose solution and measuring your blood glucose levels 2 hours later. A result of 200 mg/dL or higher indicates diabetes.
Random Plasma Glucose Test:
This test measures your blood glucose levels at any time of the day, regardless of when you last ate. A result of 200 mg/dL or higher, along with symptoms of diabetes, indicates diabetes.
Your doctor may order one or more of these tests to confirm a diagnosis of diabetes. It is important to note that a diagnosis of diabetes should always be made by a healthcare professional and not based solely on self-diagnosis or self-testing.
| Test Name | Procedure | Timing of Test | Interpretation |
|---|---|---|---|
| Fasting Plasma Glucose Test (FPG) | Blood glucose test after an overnight fast of at least 8 hours | Typically performed in the morning after an overnight fast | A result of 126 mg/dL or higher indicates diabetes |
| Hemoglobin A1c Test (HbA1c) | Blood test that measures the average blood glucose levels over the past 2-3 months | Can be done at any time of the day, regardless of food intake | A result of 6.5% or higher indicates diabetes |
| Oral Glucose Tolerance Test (OGTT) | Blood glucose test after drinking a glucose solution | Typically performed in the morning after an overnight fast | A result of 200 mg/dL or higher indicates diabetes |
| Random Plasma Glucose Test | Blood glucose test at any time of the day, regardless of when the person last ate | Can be performed at any time of the day | A result of 200 mg/dL or higher, along with symptoms of diabetes, indicates diabetes |
Please note that these tests are just a few of several tests that can be used to diagnose diabetes. The interpretation of the test results should be done by a healthcare professional.
How is diabetes managed?
Diabetes can be managed through a combination of lifestyle changes, medications, and regular monitoring. The goals of diabetes management are to keep blood sugar levels within a target range, prevent or delay complications, and improve overall quality of life. Here are some ways that diabetes can be managed:
Lifestyle changes:
This includes eating a healthy diet, getting regular exercise, maintaining a healthy weight, and quitting smoking.
Medications:
Depending on the type and severity of diabetes, medications may be prescribed to help control blood sugar levels. This may include oral medications, injectable medications, or insulin therapy.
Regular monitoring:
People with diabetes need to monitor their blood sugar levels regularly to make sure they are within the target range. This may involve using a blood glucose meter or a continuous glucose monitoring (CGM) system.
Education and support:
Diabetes self-management education can help people with diabetes learn how to manage their condition effectively. This may include learning how to count carbohydrates, administer insulin injections, monitor blood sugar levels, and manage medications.
Regular medical check-ups:
People with diabetes should have regular check-ups with their healthcare provider to monitor their blood sugar levels, blood pressure, cholesterol levels, and kidney function. They may also need to see specialists such as an endocrinologist or a podiatrist.
It is important for people with diabetes to work closely with their healthcare team to develop a personalized management plan that meets their individual needs and goals.
How can I prevent diabetes?
There are several steps you can take to reduce your risk of developing diabetes:

Chronic stress can increase your risk of developing diabetes. Find ways to manage stress such as practicing relaxation techniques, getting enough sleep, and participating in stress-reducing activities.
Know your family history:
If you have a family history of diabetes, you may be at a higher risk. Talk to your healthcare provider about your risk and steps you can take to reduce your risk.
What is the prognosis for diabetes?
The prognosis for diabetes varies depending on several factors such as the type and severity of diabetes, how well it is managed, and the presence of any complications.
If diabetes is not managed well, it can lead to several complications such as nerve damage, kidney damage, eye damage, cardiovascular disease, and lower limb amputations. These complications can significantly affect a person's quality of life and increase the risk of premature death.
However, with proper management, people with diabetes can lead a healthy and active life and reduce their risk of developing complications. This involves maintaining healthy blood sugar levels, blood pressure, and cholesterol levels, following a healthy diet, getting regular exercise, and taking medications as prescribed.
It's important for people with diabetes to have regular check-ups with their healthcare provider to monitor their blood sugar levels, blood pressure, cholesterol levels, and kidney function. Early detection and treatment of complications can help prevent or delay their progression and improve overall prognosis.
Overall, diabetes is a chronic condition that requires lifelong management, but with proper care and support, people with diabetes can lead a healthy and fulfilling life.
