What Is Diabetes?

Diabetes is a chronic condition that affects how the body processes glucose, a type of sugar, in the bloodstream. When someone has diabetes, their body either can’t produce enough insulin or can’t use the insulin it produces efficiently. Insulin is a hormone that helps the body process glucose and turn it into energy.

There are two types of diabetes, type 1 and type 2. Type 1 diabetes is an autoimmune disorder, meaning the body’s own immune system attacks the cells that produce insulin. Type 2 diabetes is caused by lifestyle factors, such as poor diet and lack of exercise, and is the most common type of diabetes.

When Does Diabetes Require Insulin?

In most cases, type 2 diabetes can be managed with diet and exercise alone. However, some people may need to take insulin to keep their blood sugar levels in check. The need for insulin is usually determined by a doctor after assessing a person’s lifestyle, diet, and medical history.

People with type 1 diabetes must take insulin to survive. Without insulin, their bodies can’t process glucose, and they can develop life-threatening complications. People with type 2 diabetes may also need to take insulin if their diabetes can’t be controlled through diet and exercise.

Signs That You Need Insulin

If you have diabetes, your doctor will likely monitor your blood sugar levels to determine if you need to take insulin. Some signs that you may need insulin include:

  • Frequent urination
  • Excessive thirst
  • Unexplained weight loss
  • Fatigue
  • Blurred vision
  • Slow-healing sores
  • Frequent infections

If you are experiencing any of the above symptoms, be sure to make an appointment with your doctor. They will be able to determine if you need to start taking insulin.

Types of Insulin

Insulin is available in different forms, and your doctor will work with you to determine the best type for you. There are two main types of insulin: short-acting and long-acting. Short-acting insulin is used to control blood sugar levels after meals, while long-acting insulin is used to control blood sugar levels throughout the day.

In addition to short- and long-acting insulin, there are also intermediate-acting and rapid-acting insulin. Intermediate-acting insulin is used to maintain blood sugar levels between meals, while rapid-acting insulin is used to quickly lower blood sugar levels.

Managing Diabetes With Insulin

Once you start taking insulin, it’s important to manage your diabetes carefully. This includes eating healthy, exercising regularly, and monitoring your blood sugar levels. It’s also important to keep your insulin doses consistent.

If you’re taking insulin, it’s important to work with your doctor to adjust your doses as needed. Your doctor may also suggest other medications, such as metformin, to help manage your diabetes. Taking the right steps can help you better manage your diabetes and keep your blood sugar levels in check.


Diabetes is a serious condition that requires careful management. It’s important to talk to your doctor if you think you may need insulin to control your diabetes. With the right lifestyle changes, medications, and regular check-ups, you can manage your diabetes and live a healthy life.
