Diabetic Pump

Individuals who have type 1 and type two 2 are required to manage their insulin levels. The typical two options for management are via insulin injections or using an insulin pump. For many people, the diabetic pump allows them to regulate their insulin levels without having to resort to regularly pricking their skin with a needle.

For some, the needle pricks are painful or simply an inconvenience. A diabetic pump offers more independence and less invasiveness.

So what should you know about pumps before you make the switch?

How Does an Insulin Pump Work?

An insulin pump is essentially a computerized device that delivers short-acting insulin to the body via a small tube. The tube is placed directly under the skin. The most attractive thing about a diabetic pump is that it releases insulin in a similar way to how the body naturally produces it.

The pump injects the body with a steady flow of insulin throughout the day and then provides a larger dose at mealtimes to help regulate levels. People must simply program the pump to inject the insulin at the rate at which they need it to. You can even make adjustments to the injections if you happen to eat more than you usually do and need a different dose of insulin to regulate your levels.

When managing diabetes via insulin injections, the individual needs to take a shot of basal insulin once per day. Basal insulin, also known as long-acting or background insulin, regulates blood sugar levels between meals. The individual will also inject bolus, also known as short-acting, insulin at mealtimes to manage increases in blood glucose levels as a result of food. Conversely, because an insulin pump injects the body with a steady flow of insulin throughout the day, the individual will no longer need to take a shot of basal insulin. Instead, they rely only on bolus insulin.

What Does a Diabetic Pump Look Like?

An insulin pump is a small device that is similar in size to a smartphone. You simply attach it to the body via a thin plastic tube with a needle or thin tube. The common areas for placement are the stomach, buttocks, or thigh. People elect to use the area that is most comfortable for them.

The pump itself can be worn around your waist in a case, can hook onto a belt or bra, be kept in a pocket, or be worn on an armband. There are many accessory options that will help make wearing a pump as convenient as possible.

Who Should Use a Diabetic Pump?

Individuals with type 1 or type 2 diabetes may benefit from using a diabetic pump. People who prefer to have the assistance of a pump and see it as an easier way to manage their insulin levels are the best candidates for this device. However, some of the drawbacks for people is that the device is attached to their body and people will see it.

It is also important that people who use the device understand that they are committing to learning how to use the device and how to operate it fully. Failure to do so will make the diabetic pump useless.
