A reader asks us, "What is hypercoagulability in type 2 diabetes all about?"
Hypercoagulability refers to a tendency of the blood to clot. It's most commonly a problem in type 2 diabetics who also have high cholesterol and high triglycerides.Sometimes doctors recommend metformin for keeping arteries open, especially for the 10% or so of type 2 diabetics in Australia, Canada, New Zealand, the UK, and the USA who also have unusually high iron levels. This treatment won't work, however, unless the diet provides enough folic acid and vitamin B12. (It's not necessary to take more than 100% of the RDI for this purpose.) Both metformin and Glucophage XR would work for this purpose.
Hypercoagulability causes two clusters of problems for type 2's. One is lower limb circulation. There is a tendency for deep vein thrombosis in type 2's with high blood sugar levels and high cholesterol levels who have to sit in a confined area for long periods. There is also a tendency toward hypercoagulability after a large, high-fat meal, although this risk passes in 4 to 8 hours--assuming the type 2 stops eating!
