What is diabetes?
Diabetes is a condition that happens when your blood sugar (glucose) is too high. It develops when your pancreas doesn’t make enough insulin or any at all, or when your body isn’t responding to the effects of insulin properly. Diabetes affects people of all ages. Most forms of diabetes are chronic (lifelong), and all forms are manageable with medications and/or lifestyle changes.
Glucose (sugar) mainly comes from carbohydrates in your food and drinks. It’s your body’s go-to source of energy. Your blood carries glucose to all your body’s cells to use for energy.
When glucose is in your bloodstream, it needs help — a “key” — to reach its final destination. This key is insulin (a hormoneIf your pancreas isn’t making enough insulin or your body isn’t using it properly, glucose builds up in your bloodstream, causing hey blood sugar (hyperglycemia)
Over time, having co high blood glucose can cause health problems, such as heart disease nerve damage and eye issues.
The technical name for diabetes is diabetes mellitus. Another condition shares the term “diabetes” — diabetes and spiders— but they’re distinct. They share the name “diabetes” because they both cause increased thirst and frequent urination. Diabetes insipidus is much rarer than diabetes mellitus.
What are the types of diabetes?
There are several types of diabetes. The most common forms include:
- Type 2 diabetes: With this type, your body doesn’t make enough insulin and/or your body’s cells don’t respond normally to the insulin (insulin resistance). This is the most common type of diabetes. It mainly affects adults, but children can have it as well.
- Prediabetes: This type is the stage before Type 2 diabetes. Your blood glucose levels are higher than normal but not high enough to be officially diagnosed with Type 2 diabetes.
- Type 1 diabetes; This type is an autoimmune disease in which your immune system attacks and destroys insulin-producing cells in your pancreas for unknown reasons. Up to 10% of people who have diabetes have Type 1. It’s usually diagnosed in children and young adults, but it can develop at any age.
- Gestational diabetes: This type develops in some people during pregnancy Gestational diabetes usually goes away after pregnancy. However, if you have gestational diabetes, you’re at a higher risk of developing Type 2 diabetes later in life.
- that affects how your body makes and uses insulin. There are currently over 10 different types of MODY. It affects up to 5% of people with diabetes and commonly runs in families.
- Neonatal diabetes: This is a rare form of diabetes that occurs within the first six months of life. It’s also a form of monogenic diabetes. About 50% of babies with neonatal diabetes have the lifelong form called permanent neonatal diabetes mellitus. For the other half, the condition disappears within a few months from onset, but it can come back later in life. This is called transient neonatal diabetes mellitus.
- Brittle diabetes is a form of Type 1 diabetes that’s marked by frequent and severe episodes of high and low blood sugar levels. This instability often leads to hospitalization. In rare cases, pancreas transplant.

- How common is diabetes?
- Diabetes is common. Approximately 37.3 million people in the United States have diabetes, which is about 11% of the population. Type 2 diabetes is the most common form, representing 90% to 95% of all diabetes cases.
About 537 million adults across the world have diabetes. Experts predict this number will rise to 643 million by 2030 and 783 million by 2045.
What causes diabetes?
Too much glucose circulating in your bloodstream causes diabetes, regardless of the type. However, the reason why your blood glucose levels are high differs depending on the type of diabetes.
Causes of diabetes include:
Insulin resistance: Type 2 diabetes mainly results from insulin resistance. Insulin resistance happens when cells in your muscles, fat and liver don’t respond as they should to insulin. Several factors and conditions contribute to varying degrees of insulin resistance, including obesity, lack of physical activity, diet, hormonal imbalances, genetics and certain medications.
Autoimmune disease: Type 1 diabetes and LADA happen when your immune system attacks the insulin-producing cells in your pancreas.
Diabetes is a chronic condition that occurs when the body either does not produce enough insulin (Type 1 diabetes) or cannot effectively use the insulin it produces (Type 2 diabetes). Insulin is a hormone that regulates blood sugar levels and allows glucose from food to enter cells for energy. When insulin function is impaired, it leads to high blood sugar levels, which can cause various health complications over time.
Causes of Diabetes:
1. 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. The exact cause of this autoimmune response is not fully understood, but genetic and environmental factors play a role.
2. Type 2 Diabetes: Type 2 diabetes is often linked to lifestyle factors, including:
- Obesity: Excess body weight, especially around the abdomen, increases the risk of insulin resistance.
- Physical Inactivity: Lack of regular physical activity can contribute to insulin resistance and weight gain.
- Unhealthy Diet: Consuming a diet high in processed foods, sugary beverages, and unhealthy fats can increase the risk of developing Type 2 diabetes.
- Genetics: Family history and genetic predisposition can also influence the risk of Type 2 diabetes.
Prevention of Diabetes:
1. Maintain a Healthy Weight: Maintaining a healthy weight through a balanced diet and regular physical activity can help prevent or delay the onset of Type 2 diabetes.
2. Eat a Balanced Diet: Focus on consuming whole foods, including fruits, vegetables, whole grains, lean proteins, and healthy fats. Limit intake of sugary foods and beverages, refined carbohydrates, and saturated fats.
3. Stay Active: Regular physical activity can improve insulin sensitivity, help manage weight, and reduce the risk of developing Type 2 diabetes. Aim for at least 150 minutes of moderate-intensity exercise per week.
4. Monitor Blood Sugar Levels: If you have prediabetes or are at risk of developing diabetes, monitoring your blood sugar levels regularly can help you make lifestyle changes to prevent progression to diabetes.
5. Manage Stress: Chronic stress can impact blood sugar levels and insulin resistance. Practice stress-reducing techniques such as mindfulness, meditation, yoga, or deep breathing exercises.
6. Get Regular Check-Ups: Regular health check-ups can help identify early signs of diabetes or prediabetes so that appropriate interventions can be implemented.
By adopting a healthy lifestyle that includes a balanced diet, regular exercise, weight management, and stress reduction techniques, you can reduce your risk of developing Type 2 diabetes and promote overall well-being. If you have concerns about your risk for diabetes, consult with a healthcare provider for personalized guidance and support.
The signs and symptoms of diabetes can vary depending on the type of diabetes and the individual's overall health. Here are some common signs and symptoms associated with both Type 1 and Type 2 diabetes:
Common Signs and Symptoms of Diabetes:
1. Frequent Urination (Polyuria): Excess sugar in the blood can cause the kidneys to work harder to filter and absorb the sugar. This can lead to increased urination, especially at night (nocturia).
2. Excessive Thirst (Polydipsia): Dehydration from frequent urination can trigger feelings of extreme thirst.
3. Increased Hunger (Polyphagia): Despite eating more, individuals with diabetes may still experience weight loss due to the body's inability to properly utilize glucose for energy.
4. Unexplained Weight Loss: Individuals with Type 1 diabetes may experience sudden weight loss despite eating well. This is due to the body breaking down muscle and fat for energy because it cannot access glucose from food.
5. Fatigue: Feeling tired and lethargic is a common symptom of diabetes, as the body's cells are not getting enough glucose for energy.
6. Blurred Vision: High blood sugar levels can cause fluid to be pulled from the lenses of the eyes, affecting vision.
7. Slow-Healing Wounds: Diabetes can impair the body's ability to heal wounds and infections, leading to slow healing or frequent infections.
8. Numbness or Tingling in Hands and Feet: Elevated blood sugar levels can damage nerves, leading to peripheral neuropathy, which causes numbness, tingling, or pain in the hands and feet.
9. Recurrent Infections: High blood sugar levels can weaken the immune system, making individuals with diabetes more susceptible to infections, especially in the skin, urinary tract, and gums.
10. Dry Skin and Itching: Diabetes can cause skin dryness and itchiness, especially around the genital area.
It is important to note that some individuals may not experience any symptoms, especially in the early stages of diabetes. Therefore, regular health check-ups and screenings are essential for early detection and management of diabetes. If you experience any of these symptoms or have concerns about your risk for diabetes, consult with a healthcare provider for proper evaluation and guidance.
When to see a Doctor
If you are experiencing signs and symptoms of diabetes, it is important to see a doctor for evaluation and diagnosis. Here are some guidelines on when to seek medical attention:
1. Persistent Symptoms: If you are experiencing persistent symptoms such as frequent urination, excessive thirst, unexplained weight loss, fatigue, blurred vision, or any other symptoms mentioned earlier, it is advisable to see a doctor for further evaluation.
2. Family History: If you have a family history of diabetes or other risk factors such as being overweight, having high blood pressure, or being physically inactive, it is recommended to get tested for diabetes even if you do not have symptoms.
3. Routine Check-ups: If you have not had a recent health check-up or blood tests to monitor your blood sugar levels, consider scheduling an appointment with your healthcare provider for routine screening.
4. Risk Factors: If you have other risk factors for diabetes, such as being over the age of 45, having a sedentary lifestyle, or belonging to certain ethnic groups (such as African American, Hispanic/Latino, Native American, or Asian American), it is important to monitor your health and discuss your risk with a healthcare provider.
5. Gestational Diabetes: If you are pregnant and experiencing symptoms of diabetes, such as excessive thirst or frequent urination, it is crucial to consult with your obstetrician or healthcare provider for evaluation and management.
6. Unexplained Symptoms: If you are experiencing unexplained symptoms that are affecting your daily life or overall well-being, it is important to seek medical advice to determine the underlying cause and receive appropriate treatment.

Autoimmune disease: Type 1 diabetes and LADA happen when your immune system attacks the insulin-producing cells in your pancreas.
Diabetes-related ketoacidosis (DKA): This complication mainly affects people with Type 1 diabetes or undiagnosed T1D. It happens when your body doesn’t have enough insulin. If your body doesn’t have insulin, it can’t use glucose for energy, so it breaks down fat instead.
This process eventually releases substances called ketones, which turn your blood acidic. This causes labored breathing, vomiting and loss of consciousness. DKA requires immediate medical treatment
Remember that early detection and management of diabetes can help prevent complications and improve your overall health outcomes. Your doctor can perform tests to diagnose diabetes and recommend appropriate treatment options based on your individual needs. If you suspect you may have diabetes or have concerns about your symptoms, do not hesitate to schedule an appointment with a healthcare provider.
