New Evidence Suggests Doctors Are Misdiagnosing a Third Type of Diabetes
The common understanding of diabetes mellitus includes two types: type one and type two. But there’s a third type that’s been around for a while you may not have even heard of—and some doctors think it’s being misdiagnosed.
Type 3c diabetes, or “Diabetes of the Exocrine Pancreas,” is a third type caused by pancreatic damage. But a recent study found that doctors were likely misdiagnosing this form of diabetes as type 2. But the two require different treatment.
“Several drugs used for type 2 diabetes, such as gliclazide, may not be as effective in type 3c diabetes,” Andrew McGovern from the University of Surry wrote in The Conversation. “Misdiagnosis, therefore, can waste time and money attempting ineffective treatments while exposing the patient to high blood sugar levels.”
Scientists have recognized other types of diabetes aside from type-1 (the body destroys its own insulin-producing cells) or type-2 (the body can’t make enough insulin) for a long time. Back in 2008, researchers worried that type 3c had been under- and misdiagnosed. A new study, published recently in the journal Diabetes Care, adds further evidence to that worry after a search through millions of health records in the United Kingdom.
The researchers found over 30,000 adult-onset cases of diabetes, and found 559 occurred after pancreatic disease. Despite the link between pancreatic disease and type 3c diabetes, 88 percent of those cases were still diagnosed with the more common type of adult-onset diabetes, type 2 diabetes and only 3 percent diagnosed as type 3c—implying at least so Continue reading
