Insulin is a lifesaving drug for millions of Americans with diabetes. But sadly, many of them can’t always afford the amount of insulin they need, according to a new study. Insulin rationing is commonplace in America. It’s also a dangerous practice. But there is help.

More than 7 million adults living in the U.S. use insulin injections to regulate their blood sugar levels. A new study published in the journal Annals of Internal Medicine estimated that nearly 1 in 5 of those living with diabetes may have rationed insulin in the past year.

Who’s Skipping Insulin Doses?

Insulin rationing was most common, the study found, among Black Americans  — just over 23% — compared to about 16% for white and Hispanic Americans.

Younger adults are about twice as likely as people over age 65 to ration insulin.

Why Is It Dangerous to Ration Insulin?

We turned to a UVA Health diabetes expert, endocrinologist Meaghan Stumpf, MD.

She explains: “For many people with diabetes, we can manage their condition with medications other than insulin and with lifestyle changes. But when these measures aren’t enough to lower blood sugar levels, then insulin injections become a necessity. We only prescribe insulin to our patients who need it."

She adds, “We call these diabetes patients insulin-dependent.”

Skipping or not taking enough insulin causes hyperglycemia, or high blood sugar. This can quickly dehydrate someone who is insulin-dependent. Over time, if your blood sugar is consistently too high, you could experience:

In the worst cases, skipping insulin doses can lead to an amputation, or even cause a life-threatening condition.

“If someone with type 1 diabetes skips insulin doses, they can quickly slip into a coma and die,” Stumpf explains.
