Insulin Pump Therapy: Who, Why, and How

Q When should patients consider using an insulin pump?

Patients with type 1 or type 2 diabetes can benefit from an insulin pump. In particular, they can be useful for patients who

Are tired of multiple daily injections. Insulin is still bolused at mealtime—just electronically.

Require a tailored approach. Multiple basal settings can be programmed to reflect activity and work level; some patients need more insulin on active days and less on sedentary days.

Have an on-the-go lifestyle. Insulin pumps replace multiple daily injections, as noted, which helps when patients miss manual injections due to accessibility issues.

Value discretion. Those who wear restrictive uniforms for work or simply desire privacy may benefit from an insulin pump model that can bolus via remote control, without physical access to the pump.

Have found other treatments suboptimal. Some insurers allow patients to try a pump before a decision is made.

Experience hypoglycemia unawareness. Some pumps work with CGMs to suspend insulin delivery with a low glucose level; proper use of a pump can help to restore patient awareness of their condition.

Are sensitive to insulin. Select pumps can deliver insulin at a rate of one-hundredth of a unit at a time.

Experience the dawn phenomenon or Somogyi effect. Patients with high early-morning glucose levels can adjust their rates to combat hyperglycemia, and those with overnight lows and rebounding hyperglycemia can adjust their basal rates or nighttime snacking settings to prevent this occurrence.
