Quick Answer: What Is Diabetes?
Diabetes is a chronic condition that affects the body's ability to use glucose, a type of sugar that provides energy to cells. It develops when the body does not produce enough insulin or cannot use insulin effectively, which may lead to elevated blood sugar levels over time.What Is Diabetes?
Diabetes is a metabolic condition that affects millions of people worldwide. The body relies on glucose for energy, and insulin helps move glucose from the bloodstream into cells. When insulin production is insufficient or insulin does not work properly, glucose can remain in the bloodstream instead of entering cells. Over time, elevated blood sugar levels may affect various organs and systems throughout the body. Diabetes can affect individuals of different ages and backgrounds. Some forms develop during childhood, while others are more commonly diagnosed in adulthood. Understanding diabetes may help individuals recognize symptoms, learn about risk factors, and work with healthcare professionals to manage the condition effectively.Quick Facts About Diabetes
| Fact | Information |
|---|---|
| Condition Type | Chronic metabolic disorder |
| Main Concern | Elevated blood sugar levels |
| Hormone Involved | Insulin |
| Common Types | Type 1, Type 2, Gestational |
| Common Symptoms | Increased thirst, frequent urination, fatigue |

Types of Diabetes
Type 1 Diabetes
Type 1 diabetes occurs when the immune system attacks insulin-producing cells in the pancreas. As a result, the body produces little or no insulin. This type often develops during childhood or adolescence, although adults may also be diagnosed.Type 2 Diabetes
Type 2 diabetes is the most common form of diabetes. It develops when the body's cells become less responsive to insulin, a condition often called insulin resistance. Over time, the pancreas may struggle to produce enough insulin to maintain healthy blood sugar levels.Gestational Diabetes
Gestational diabetes develops during pregnancy and may affect blood sugar regulation. Although blood sugar levels often return to normal after pregnancy, some individuals may have a higher risk of developing type 2 diabetes later in life.Symptoms of Diabetes
Symptoms can vary from person to person. Some individuals experience noticeable symptoms, while others may not recognize signs until routine testing identifies elevated blood sugar levels. Common symptoms may include:- Increased thirst
- Frequent urination
- Increased hunger
- Fatigue
- Blurred vision
- Unexplained weight loss
- Slow-healing wounds
- Frequent infections
- Tingling or numbness in the hands and feet
Causes and Risk Factors
The causes of diabetes differ depending on the type.Common Risk Factors for Type 2 Diabetes

Type 1 Diabetes Risk Factors
Researchers continue to study factors that may contribute to type 1 diabetes. Genetics and immune system responses are believed to play important roles. Having one or more risk factors does not necessarily mean a person will develop diabetes. Learn More Read our guide on What Causes Diabetes?
