So, got up this morning (late) and this is still rumbling.
Lucylocket gave an easy and quick description of all this.
I'll try and re-iterrate for the last time,
There are lots of reasons why people may not feel safe to drive. A dose of Flu or a cold. A migraine. Low blood sugar, be you diabetic or not. Simples. If you don't feel safe to drive, don't drive.
BUT
If you are going to tell all diabetics to test BGs before driving (as has been suggested here), you might as well tell the entire population to test before driving. Practical? No. Necessary? No.
Because diabetes in itself does NOT cause hypos. Nor does Metformin. LOTS of links have been shown on this thread to medical sites saying Metformin doesn't cause hypos. NOT ONE has been shown saying it does. Here's another from the American Diabetes Association:-
"Biguanide (by-GWAH-nyd)
Brand Name Generic Name
__ Glucophage (GLOO-coh-fahj) __ metformin (met-FOR-min)
__ Glucophage XR __ metformin-long-acting
__ Riomet (RY-oh-met) __ metformin-liquid
What does this type of medicine do?
This type of medicine, which comes in pill or liquid form, lowers the amount of glucose made by your liver. Then your blood glucose levels don’t go too high. This type of medicine also helps treat insulin resistance. With insulin resistance, your body doesn’t use insulin the way it should. When your insulin works properly, your blood glucose levels stay on target and your cells get the energy they need. This type of medicine improves your cholesterol levels. It also may help you lose weight.
...................................
What are the possible side effects?
This type of pill doesn't cause low blood glucose by itself. But your risk of having low blood glucose goes up if you also take
•diabetes pills that cause low blood glucose
•insulin
Which is exactly, and all, we have been saying. Metformin on it's own does NOT cause hypos. So diet only patently doesn't either. If you have a link saying Metformin causes hypos, PLEASE share it with us. Please also share any links you have that show diabetics on diet only are at risk of hypos.
So, if you're poorly and can't drive, don't. If you have low blood sugar don't blame it on your metformin, blame it on a lack of food with exercise or another medical condition. Lots of people like Lucylocket have low blood sugar without diabetes.
So I suggest we stop telling new diabetics on diet only/metformin that they may get "hypos"; we all know the connotation of this to new diabetics. If you want to tell them that if they reduce their food intake too far because of their diagnosis that they may get low blood sugar the same as anybody else, fine. Don't tell them their metformin may cause it. And let's remember that the biggest challenge we have with most new type 2's is in STOPPING them from eating bread, sugar, bakery products and so on. Let's not give them an excuse to eat those things everytime they THINK their blood sugar is going too low, because maybe they're not used to lower more normal BGs, when for the vast majority getting out of double figures is the first challenge. Remember, a new diabetic is hopefully changing their diet radically, might be exercising for the first time in ages, will have lowering blood sugar levels, will be frightened and maybe depressed; ALL of these things can lead them to feel unwell, nauseous, giddy and so on. No wonder they make think "this is a hypo" when they've been told they can get them. Let's start distinguishing between true HYPOS and the low blood sugar spells that changes to diet and exercise regimes can bring.
