Cinnamon for diabetes? The consequences of “natural alternatives”

A customer strolled up to the counter one night when I was working in a retail pharmacy:

“My doctor says I have prediabetes. I don’t want to take any drugs. Do you have something natural I can use to cut my blood sugar?”

I looked at him in the eye, and pointed at his sizeable midsection. “Sir, if you’re at risk for diabetes, and you don’t want to take medication, the single best thing you can do for yourself is lose some weight.”

He grinned and asked, “Great – what supplement can I take to help me?”

This type of discussion occurs all the time. A patient has been assessed by their physician, and informed that they have a medical problem of some sort. The patient, reluctant to accept the physician’s evaluation, heads to the pharmacy for a second opinion. In some cases, the patient may question the physician’s advice: “All my physician wants to do is prescribe drugs.” Yet there’s a disconnect when it comes to strategies for management. More often than not, non-drug approaches are rejected out-of-hand (probably because the sample I speak with have already made the decision to buy something). And in those that are leery of medical management, there’s often a willingness to consider anything that’s available without a prescription – particularly if it’s perceived as “natural.” Natural products are gentle, safe, and effective, while medicine is thought of as unnatural, harsh, and potentially dangerous. This is the naturalistic fallacy, nothing more. Purveyors of supplements leverage the naturalistic fallacy into the marketing strategy of choice for almost all supplements and “alternative” medicines.  And it leads to bad health care decisions.

Re-evaluating Home Monitoring for Diabetes: Science-Based Medicine at Work

There is no question that patients on insulin benefit from home monitoring. They need to adjust their insulin dose based on their blood glucose readings to avoid ketoacidosis or insulin shock. But what about patients with non-insulin dependent diabetes, those who are being treated with diet and lifestyle changes or oral medication? Do they benefit from home monitoring? Does it improve their blood glucose levels? Does it make them feel more in control of their disease?

This has been an area of considerable controversy. Various studies have given conflicting results. Those studies have been criticized for various flaws: some were retrospective, non-randomized, not designed to rule out confounding factors, high drop-out rate, subjects already had well-controlled diabetes, etc. A systematic review showed no benefit from monitoring. So a new prospective, randomized, controlled, community based study was designed to help resolve the conflict. (more…)
