The body is unable to make enough insulin or use the insulin properly

The condition you are referring to is called diabetes. Diabetes occurs when the body is unable to produce enough insulin or cannot effectively use the insulin it produces. Insulin is a hormone that helps regulate the level of glucose (sugar) in the bloodstream. When insulin is not properly regulated, it can lead to high blood sugar levels, which can have various negative effects on the body.

There are two main types of diabetes: type 1 and type 2. In type 1 diabetes, the body's immune system mistakenly attacks and destroys the insulin-producing cells in the pancreas. This results in little to no insulin production, and people with type 1 diabetes require regular insulin injections to manage their blood sugar levels.

Type 2 diabetes, on the other hand, is typically caused by a combination of genetic and lifestyle factors. In type 2 diabetes, the body becomes resistant to the effects of insulin, or the pancreas does not produce enough insulin to meet the body's needs. This can be managed through various methods, including lifestyle changes such as diet and exercise, oral medications, and sometimes insulin injections.

To determine whether someone has diabetes, medical professionals use several tests. The most common test is a fasting blood sugar test, which measures the amount of glucose in the blood after an overnight fast. Another test is the oral glucose tolerance test, where a person drinks a sweet solution and their blood sugar levels are measured over time.

If you suspect that you or someone you know may have diabetes, it is important to consult a healthcare professional for diagnosis and appropriate treatment. They will be able to provide proper guidance and help manage the condition effectively.
