What Type of Insulin Goes Into an Insulin Pump? a Helpful Guide

Insulin pumps are effective forms of diabetes equipment that diabetes patients use to manage their condition. However, many things about how this piece of equipment works leave people confused and with many questions unanswered.

One of these areas of confusion is the question of what type of insulin goes into an insulin pump. And does it matter what insulin is used in an insulin pump? 

This article will give a clear understanding of what types of insulin go into an insulin pump. But first, let’s give a quick summary of what type of insulin goes into an insulin pump, then we’ll get into more explanation as to why.

What type of insulin goes into an insulin pump?  Short-acting or fast-acting insulin, like Aspart, Lispro, and Glulisine, is what goes into an insulin pump. This helps insulin pumps work similarly to the natural pancreas of an average person. However, basal-bolus insulin therapy replaces the need to use both short-acting and long-acting insulin. 

So, now we’ve seen the quick rundown answer, let’s take a deeper dive into some of the nuances of this question.

What Type of Insulin Goes Into an Insulin Pump?

What Type of Insulin Goes Into an Insulin Pump

An insulin pump is aimed at providing continuous delivery of insulin all day long. The reason for using an insulin pump is to substitute the use of injections or long-acting insulin daily. This is because an insulin pump releases insulin when the body needs it. And in an insulin pump, several settings can be adjusted to provide insulin as and when needed. 

So, for these reasons, only rapid-acting insulin and sometimes regular insulin should be used in an insulin pump.

Rapid-acting insulin types used are ones such as Aspart, Lispro, and Glulisine. The reason for using short-acting insulin is because the pump can deliver a continuous drip of insulin all day long (basal rate). And a mealtime or correction dose (bolus) can be easily delivered with just a push of a button. 

Regular may be able to be used in an insulin pump. However, it is not as likely or recommended. Your doctor will prescribe the insulin they believe is best for you.

Since short-acting insulin delivers insulin every few minutes, the maintenance and control of blood glucose levels are maintained in a stable manner. This also avoids the need to use long-acting insulin and the injections that come along with that. 

The benefit of using short-acting insulin is that they start working within 10-15 minutes and peak at about an hour after absorption. The duration of rapid-acting insulin is typically around 3-4 hours. 

High blood sugar levels are easily managed and controlled, avoiding situations of hyperglycemia when using rapid-acting insulin in inulin pumps. 

Sadly, although pumps provide many benefits, not all patients are good insulin pump candidates. This is because the psychological readiness and physiological needs of diabetes patients vary with individuals and need to be considered.

How Short-Acting Insulin Works Inside an Insulin PUMP?

What Type of Insulin Goes Into an Insulin Pump

The insulin pump is about the size of a card deck or small smartphone, depending on the brand. It is worn outside the body, and the insulin is delivered through a tube. This thin tube is connected to a cannula, which is placed into a layer of fat under the skin. 

There is a tubeless pump that is also known as a patch pump. It works similar to the way other insulin pumps work. For the pumps that have a tube, they have to be attached to the person in some way. This may mean placing the device in a pocket or on a belt or bra.

As to how the insulin pumps work when short-acting insulin is used can be better explained by comparing it to the pancreas of a person without diabetes. This is because insulin pumps work pretty much like the natural pancreas. 

The pancreas is an organ that is deep in the abdomen behind the stomach. This organ is an essential part of the digestive system that produces enzymes and hormones that help in digesting food. One such hormone is insulin.

Insulin is a hormone that is a very important element in regulating glucose (blood sugar levels).

Every cell in a human body needs glucose for generating energy. But insulin is more like the lock to these cells. If the insulin can open up the cell, the cell can then use glucose for energy.

If this fails, the glucose remains unregulated and unused, raising blood sugar levels leading to diabetes.

So, it’s due to the pancreas not producing enough insulin (type 1 diabetes) or not making good use of the insulin produced (Type 2 diabetes), that needs to be corrected by diabetes medications. Insulin pumps help us to do this

So, what the pancreas should do is detect a rise in the blood sugar levels (glucose levels) and release insulin to make energy out of glucose. Insulin pumps imitate the release of insulin, normally produced by the pancreas. 

Insulin pumps regularly release short doses of insulin into the body, just like a natural pancreas would. Each patient will have their own basal rate, usually recommended by your doctor.  However, blood sugar levels can still spike after eating. So, you can easily enter the amount of insulin in the pump needed to keep blood sugar levels from spiking after eating.

Most pumps on the market today have a built-in bolus calculator. This means that the patient will enter their insulin-to-carb ratio when they initially set up their pump. Once that is plugged in, they just have to enter the amount of carbohydrates they will consume at each meal. From there, the pump automatically calculates how much insulin is needed for a bolus.

Compare insulin pump use with multiple daily injections.
