Usually, people diagnosed with Type 1 diabetes are regular users of the insulin pump. Nowadays, people with type 2 diabetes are also beginning to use the pump, which provides better control over diabetes.

What Is Diabetes?

Diabetes is a condition where the sugar levels in the blood remain high. This is because of the pancreas, which is responsible for secreting insulin in the body, is not able to produce insulin. In some cases, the insulin produced is not enough for the body. In such cases, insulin is to be taken externally, to keep the sugar levels intact to avoid further complications.

What Is An Insulin Pump?

 Insulin Pump Therapy

An insulin pump is a device that is fitted to your body, which replicates the action of the pancreas. It is about the size of a cellphone and contains a small screen and a few buttons. It is filled with fast acting insulin in the form of cartridges and a precise motor. This motor helps in giving you the dose of the insulin. The insulin goes into your body through a thin plastic tube called the cannula. The pump is already programmed internally, to inject the insulin doses.

How Does An Insulin Pump Work ?

These insulin pumps are programmed to deliver fast acting or rapid insulin all throughout the day. These insulin doses are categorized into

  1. Basal Rates
  2. Bosul Doses
  3. Supplemental or Correction Doses

Basal Rates

These basal rates are programmed insulin rates that are given continuously in small quantities. It mimics the working of the pancreas in the body.  Generally, these basal rates are determined by your doctor based on your daily needs. The delivery of these basal rates can also be customized, i.e it can be can increased or decreased based on your daily routine.

Bosul Doses

Bosul Doses are additional doses that can be taken based on the food that you are going to take. These insulin pumps have calculators, which help in calculating the bosul doses. These calculations will already be pre-set by your doctor based on your special needs.

Supplemental or Correction Rates

As the name suggests, when your blood sugar levels are high before your meal, you can take a correction dose. This will help you in bringing back your blood sugar levels within the required range.
