If you’re the betting type, the over/under on the Browns quarterback Baker Mayfield's passing yards for the 2019 season is 4,325.5. That's a higher number than the odds makers are giving Super Bowl champ Tom Brady (4,170.5).

How will the season play out? Who knows? But over/under wagers are tricky, and losses can be devastating.

Just ask the almost 30 million Americans with Type 2 diabetes, many of whom are over- or undertreated.

The over: According to a study in the journal Mayo Clinic Proceedings, 20% of people with Type 2 diabetes are over-controlling their glucose levels with “intensive therapy,” risking hospitalization, even death, from hypoglycemia (low blood sugar). They're taking one type of medication to achieve an A1C measure of 5.6% or under, or taking two or more types to achieve an A1C of 5.7-6.4%.

The under: Research shows that only 67%-85% of oral medication doses and 60% of insulin doses are actually taken, increasing the risk for neuropathy, retinopathy, and cardiovascular, kidney, and digestive disease.

We advocate working to reverse Type 2 diabetes with improved nutrition and regular physical activity. That can take you safely to a 5.7% A1C or lower.

If you're taking medications for “intensive therapy” and have end-stage kidney disease, three or more chronic conditions (high blood pressure, arthritis, plus diabetes, for example), or are age 75 or older, ask your doctor about setting a less-risky target for your A1C.

If you're not following your medication regimen, tell your doctor, give lifestyle changes a try, and see a diabetes educator for help managing your disease more effectively.
