Low Blood Sugar

You should not have Hypoglycaemia from taking metformin, but it is not unknown.
Are you taking any other meds, that might be causing the lows?

How long after food did you test?

What are your fasting blood glucose levels?

What are your other symptoms?

Sorry for the questions, but to help you, there maybe other things that you may not have realised what is going on.

You do need to speak to your GP regardless, if you have recurring episodes of Hypoglycaemia.

Best wishes

Sorry, more questions.

I'm not certain that cocktail of drugs are would cause hypos but I wouldn't rule it out!

Are the hypos worse after a relatively high carb meal say breakfast cereals or a sandwich?
Have you an ulcer?

Any other symptoms even if it is very similar to T2?

But my recommendation is still to speak to your GP.
Do you keep a food diary as this will help your GP see what is happening?

Have you had a hypo, then found you have high blood glucose levels, then low again?

The reason I'm asking is because I have a condition that started very similar to yours.
I had an ulcer, but it was caused by bad bacteria, that was over ten years ago.
Not had heartburn, dyspepsia or ulcer since.
My condition has hypoglycaemic episodes.
Maybe, go read the Reactive Hypoglycaemia forum might help you develop the questions you can ask your GP.
If these hypos continue, I would ask for a referral to a specialist endocrinologist.

Best wishes
