What is diabetes?

 A blood sugar (glucose) level that is too high results in diabetes. It arises when your body isn't reacting to the effects of insulin appropriately or when your pancreas produces too little or no insulin at all. People of all ages are affected by diabetes.

All types of diabetes are treatable with medicine and/or lifestyle modifications, and the majority are chronic (lifelong).

The primary source of glucose, or sugar, is found in the carbs in food and beverages. It serves as your body's primary energy source.

All of the cells in your body receive glucose from your blood to utilise as fuel.

Once in your bloodstream, glucose need assistance—a "key"—to go where it needs to go. Insulin is the hormone that is crucial. If there is insufficient insulin produced by your pancreas.

What are the types of diabetes?

There are several types of diabetes, each with its own causes, symptoms, and treatment approaches. The main types of diabetes include:

1. Type 1 diabetes: This type of diabetes is an autoimmune condition in which the immune system attacks and destroys the insulin-producing cells in the pancreas. People with type 1 diabetes require insulin injections to manage their blood sugar levels.

2. Type 2 diabetes: Type 2 diabetes is the most common form of diabetes and is often associated with lifestyle factors such as poor diet, lack of exercise, and obesity. In type 2 diabetes, the body becomes resistant to insulin or does not produce enough insulin to maintain normal blood sugar levels. Type 2 diabetes can sometimes be managed through lifestyle changes, medication, or insulin therapy.

3. Gestational diabetes: This type of diabetes occurs during pregnancy and usually resolves after giving birth. Gestational diabetes can increase the risk of complications during pregnancy and delivery, as well as the risk of developing type 2 diabetes later in life.

4. 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. People with prediabetes are at increased risk of developing type 2 diabetes if lifestyle changes are not made.

5. Monogenic diabetes: This rare form of diabetes is caused by mutations in a single gene and can be inherited from one or both parents. Monogenic diabetes is often diagnosed in children or young adults and may not require insulin treatment.

6. Other specific types: There are other specific types of diabetes, such as cystic fibrosis-related diabetes, steroid-induced diabetes, and neonatal diabetes, among others. These types of diabetes have unique causes and treatment considerations.

What are the symptoms of diabetes?

The symptoms of diabetes can vary depending on the type of diabetes and individual factors. However, some common symptoms of diabetes include:

1. Increased thirst: Excessive thirst (polydipsia) is a common symptom of diabetes, as high blood sugar levels can cause dehydration.

2. Frequent urination: Excessive urination (polyuria) is another common symptom of diabetes, as the kidneys work to eliminate excess sugar from the body through urine.

3. Fatigue: Feeling unusually tired or fatigued can be a sign of diabetes, as the body's cells may not be getting enough energy due to insulin resistance or insufficient insulin production.

4. Weight loss: Unexplained weight loss, despite increased appetite, can be a symptom of type 1 diabetes, as the body breaks down muscle and fat for energy when it cannot use glucose properly.

5. Increased hunger: Excessive hunger (polyphagia) can occur in diabetes, especially in type 1 diabetes when the body is unable to use glucose for energy.

6. Blurred vision: High blood sugar levels can cause changes in the shape of the lens in the eye, leading to blurred vision or other vision problems.

7. Slow-healing wounds: Diabetes can impair the body's ability to heal wounds and infections, leading to slow-healing sores or frequent infections.

8. Numbness or tingling: Nerve damage (neuropathy) caused by diabetes can result in numbness, tingling, or pain in the hands, feet, or other areas of the body.

9. Recurring infections: Diabetes can weaken the immune system, making individuals more susceptible to infections such as urinary tract infections, skin infections, and yeast infections

What causes diabetes?

Diabetes is a complex condition that can be caused by a combination of genetic, environmental, and lifestyle factors. The two main types of diabetes, type 1 and type 2, have different underlying causes:

1. Type 1 Diabetes:

- Type 1 diabetes is an autoimmune disease where the body's immune system mistakenly

attacks and destroys insulin-producing beta cells in the pancreas.

- The exact cause of type 1 diabetes is not fully understood, but it is believed to involve a combination of genetic predisposition and environmental triggers, such as viral infections or exposure to certain toxins.

- Type 1 diabetes is usually diagnosed in children and young adults, and individuals with this type of diabetes require lifelong insulin therapy to manage their blood sugar levels.

2. Type 2 Diabetes:

- Type 2 diabetes is characterized by insulin resistance, where the body's cells do not respond effectively to insulin, leading to high blood sugar levels.

- Risk factors for type 2 diabetes include obesity, physical inactivity, unhealthy diet, family history of diabetes, and advancing age.

- Lifestyle factors such as poor diet, lack of exercise, and excess body weight play a significant role in the development of type 2 diabetes. 

- Genetics also play a role in type 2 diabetes, as certain genetic variations can increase the risk of developing the condition.

Other types of diabetes, such as gestational diabetes (diabetes that develops during pregnancy) and monogenic diabetes (caused by mutations in a single gene), have their own specific causes.

It's important to note that while certain risk factors can increase the likelihood of developing diabetes, the exact cause of the condition can vary from person to person. Managing diabetes often involves a combination of medication, lifestyle changes, and monitoring blood sugar levels to help control the condition and reduce the risk of complications.

What are the complications of diabetes?

Diabetes can lead to various complications that affect different parts of the body. Some of the common complications associated with diabetes include:

1. Cardiovascular Complications:

- Heart disease: Diabetes increases the risk of developing heart disease, including coronary artery disease, heart attack, and stroke.

- High blood pressure: Diabetes can contribute to high blood pressure, which further increases the risk of heart disease and other cardiovascular problems.

2. Neuropathy:

- Diabetic neuropathy: Nerve damage caused by diabetes can result in symptoms such as

numbness, tingling, pain, or weakness in the extremities. It can also affect digestion, sexual function, and other bodily functions.

3. Nephropathy:

- Diabetic nephropathy: Diabetes can damage the kidneys over time, leading to reduced kidney function or even kidney failure. This condition requires close monitoring and management to prevent complications.

4. Retinopathy:

- Diabetic retinopathy: Diabetes can damage the blood vessels in the retina, leading to vision problems and potential blindness if left untreated.

5. Foot Complications: 

- Diabetic foot problems: Nerve damage and poor circulation in the feet can lead to foot ulcers, infections, and in severe cases, amputation. 

6. Skin Complications:

- Skin conditions: People with diabetes are more prone to skin problems, such as bacterial and fungal infections, as well as slow wound healing.

7. Dental Complications:

- Gum disease: Diabetes increases the risk of gum disease, which can lead to tooth loss if not properly managed.

8. Mental Health Complications:

- Depression: Diabetes is associated with a higher risk of depression and other mental health issues due to the stress of managing a chronic condition.

It's essential for individuals with diabetes to work closely with healthcare providers to monitor and manage their condition effectively. Controlling blood sugar levels, maintaining a healthy lifestyle, taking medications as prescribed, and attending regular check-ups can help reduce the risk of complications and improve overall quality of life for those living with diabetes.

How is diabetes diagnosed?

Diabetes can be diagnosed through various tests that measure blood sugar levels. The most common tests used to diagnose diabetes include:

1. Fasting Plasma Glucose (FPG) Test: This test measures blood sugar levels after fasting for at least 8 hours. A fasting blood sugar level of 126 milligrams per deciliter (mg/dL) or higher on

two separate occasions indicates diabetes.

2. Oral Glucose Tolerance Test (OGTT): This test involves fasting overnight and then drinking a sugary solution. Blood sugar levels are measured before and 2 hours after consuming the solution. A blood sugar level of 200 mg/dL or higher after 2 hours indicates diabetes.

3. Hemoglobin A1c Test: This test measures the average blood sugar levels over the past 2-3 months. An A1c level of 6.5% or higher indicates diabetes.

4. Random Plasma Glucose Test: This test measures blood sugar levels at any time of the day, regardless of when the person last ate. A blood sugar level of 200 mg/dL or higher, along with symptoms of diabetes, may indicate diabetes.

5. Glycated Albumin Test: This test measures the percentage of glycated albumin in the blood, providing information about blood sugar levels over the past 2-3 weeks.

6. C-peptide Test: This test measures the level of C-peptide, a byproduct of insulin production, to determine if the body is producing enough insulin.

If any of these tests indicate diabetes, healthcare providers may conduct additional tests to confirm the diagnosis and determine the type of diabetes (Type 1, Type 2, gestational diabetes, etc.). Early diagnosis and appropriate management are crucial in controlling blood sugar levels and preventing complications associated with diabetes. It's important to consult a healthcare professional for proper evaluation and guidance if you suspect you may have diabetes.
