Diabetes
What is an insulin pump and how does it work?
An insulin pump is a small computerized device that is worn external to your body and has a plastic tube called a cannula, that is inserted through the skin into the fatty tissue with the aid of a small needle.
An insulin pump can be a welcomed relief for people with diabetes who are tired of injections. It can deliver insulin in two ways; in a steady and continuous dose “the basal insulin” and as a surge dose “bolus” around mealtime.
The insulin pump may integrate with your continuous glucose monitor (CGM).
Who should use a pump?
The insulin pump is just a different tool to deliver insulin. You can still manage your diabetes with injections but people who may benefit from a pump are:
- People who like the idea of a pump.
- Women planning pregnancy
- Active people, who benefit from adjustment in basal rate when they are exercising
- People who have gastroparesis
- People with brittle diabetes
- People with frequent hypoglycemia
What is a continuous glucose monitoring system (CGMs) such as Freestyle Libre or Dexcom?
A continuous glucose monitor (CGM) is a gadget that checks your glucose levels every few minutes and displays your blood sugars in a graphical form. This helps to reduce or eliminate finger testings of blood glucose. These devices enable patients with diabetes to take control of their diabetes and result in an incredible improvement in diabetes care. CGMs help alert patients if their blood glucose is too high or too low, which helps prevent glucose fluctuations.
A glucose sensor is attached to the skin. The sensor then sends information about your glucose levels to an outer receiver, a separate device, or your smartphone. Several CGMs utilize a remote application that can transmit this information to your phone, smartwatch, or even to your doctor. The data from CGMs helps to assist with adjusting your insulin regimen and your diabetes medications.
