Explanation:
Diabetes:
- Diabetes is a chronic disease characterized by high blood sugar levels.
- It occurs when the body cannot effectively use or produce enough insulin, a hormone that regulates blood sugar levels.
Insulin and Pancreas:
- Insulin is produced by the pancreas, an organ located in the abdomen.
- The pancreas is responsible for the secretion of insulin in response to high blood sugar levels.
- Insulin helps transport glucose (sugar) from the bloodstream into cells, where it is used for energy.
- In diabetes, there is either an insufficient production of insulin or the body becomes resistant to its effects.
Types of Diabetes:
1. Type 1 Diabetes:
- In Type 1 diabetes, the immune system mistakenly attacks and destroys the insulin-producing cells in the pancreas.
- This results in little to no insulin production.
- Type 1 diabetes is usually diagnosed in childhood or adolescence.
2. Type 2 Diabetes:
- Type 2 diabetes is the most common form of diabetes.
- It occurs when the body becomes resistant to insulin or does not produce enough insulin to maintain normal blood sugar levels.
- Lifestyle factors such as unhealthy diet, lack of physical activity, and obesity contribute to the development of type 2 diabetes.
- Type 2 diabetes can develop at any age, but it is more common in adults.
Conclusion:
- While it is true that diabetes is caused by an insufficient secretion of insulin or a lack of response to insulin, it is important to note that this can be due to various factors such as autoimmune destruction of insulin-producing cells (Type 1 diabetes) or insulin resistance (Type 2 diabetes).
- Therefore, the statement "Diabetes is caused by less secretion of insulin by the pancreas" is generally true, but it does not encompass all the complexities and factors involved in the development of diabetes.

Understanding Diabetes and Insulin Secretion
Diabetes is a chronic condition that arises when the body cannot effectively manage blood sugar levels. A critical factor in this process is the secretion of insulin by the pancreas.
Role of Insulin
- Insulin is a hormone produced by the pancreas that helps regulate blood glucose levels.
- It facilitates the uptake of glucose by cells, allowing them to use it for energy or store it for later use.
Causes of Diabetes
- Type 1 Diabetes:
- This is an autoimmune condition where the immune system attacks and destroys insulin-producing beta cells in the pancreas, leading to little or no insulin production.
- Type 2 Diabetes:
- In this form, the pancreas may produce insulin, but the body's cells become resistant to its effects. Over time, the pancreas may become unable to produce sufficient insulin to maintain normal blood glucose levels.
Conclusion
- The statement that "Diabetes is caused by less secretion of insulin by the pancreas" is true, particularly relevant to Type 1 diabetes and advanced stages of Type 2 diabetes.
- Insufficient insulin secretion leads to elevated blood glucose, which can result in various health complications if not managed properly.
Understanding the role of insulin is crucial for comprehending how diabetes affects the body and the importance of maintaining balanced blood sugar levels.
