Research has shown that most people with diabetes have LowB1 and that it is common in people who have chronically consumed excessive amounts of alcohol (either currently or in the past). It is common in the elderly and the obese. It is also common in a variety of other conditions. In short, the most current research on the issue would indicate that many millions of Americans may suffer from LowB1. This helps to explain why so many people suffer from numbness, tingling, burning, and pain in their feet and legs.
