Insulin Therapy: What the General Public Needs to Know

What is Insulin Therapy?

Insulin therapy is a treatment that helps control blood sugar levels. Doctors often use it for people with diabetes. In fact, insulin is a hormone made by the pancreas. It helps move sugar from the blood into the body’s cells for energy. When the body does not make enough insulin, or cannot use it well, blood sugar rises. Therefore, insulin therapy gives the body the insulin it needs to stay healthy.

Who Needs Insulin Therapy?

Many people with diabetes may need insulin therapy. For example, all people with type 1 diabetes must use insulin. Their bodies do not make any insulin. Some people with type 2 diabetes also need insulin therapy. This happens when other treatments do not keep blood sugar in a safe range. Sometimes, pregnant women with gestational diabetes may need insulin too. Your doctor will decide if insulin therapy is right for you.

Types of Insulin and How They Work

There are several types of insulin. Each type works at a different speed and lasts for a different time. Knowing the types helps you understand your treatment plan. The main types include:

Rapid-acting insulin: Starts working within 15 minutes. It controls blood sugar during meals.

Short-acting insulin: Begins to work in 30 minutes. It also helps with meals but lasts a bit longer.

Intermediate-acting insulin: Takes 2 to 4 hours to start. It keeps blood sugar steady for about half a day.

Long-acting insulin: Works slowly and lasts up to 24 hours. It helps keep blood sugar stable all day and night.

Sometimes, doctors use a mix of these insulins for the best results. Always follow your doctor’s advice on which type to use.

How is Insulin Therapy Administered?

Insulin therapy can be given in different ways. Most people use small needles or pens to inject insulin under the skin. Some use insulin pumps, which deliver insulin through a tiny tube. Let’s look at the main methods:

Insulin injections: You use a syringe or pen to inject insulin into the fatty part of your skin.

Insulin pens: These are easy-to-use devices that look like large pens. They have pre-filled insulin cartridges.

Insulin pumps: These are small machines worn outside the body. They give a steady flow of insulin through a tube.

Your doctor will help you choose the best method for your needs. With practice, giving insulin becomes easier.

Benefits and Risks of Insulin Therapy

Insulin therapy has many benefits. Most importantly, it helps control blood sugar and prevents serious health problems. For example, it can lower the risk of heart disease, kidney damage, and nerve problems. However, there are some risks to consider. The most common risk is low blood sugar, also called hypoglycemia. This can happen if you take too much insulin or skip meals. Other possible side effects include weight gain or mild skin reactions at the injection site. According to the CDC and WHO, the benefits of insulin therapy often outweigh the risks when used correctly.
