Hi
@Tina conno and welcome
Sounds like you’re having a rough time. There are possibly 2 things going on. Firstly your blood sugars are running high and secondly you have an upset stomach. The second could be making the first worst.
In your shoes I would definitely try and contact my GP surgery either by telephone or if they use the e-consult service, that is very effective.
In terms of the blood sugar levels, @JoKalsbeek’s advice to reduce your intake of carbohydrates is a good one and will help. In addition to the links she shared, please have a read of this:
https://www.diabetes.co.uk/forum/threads/basic-information-for-newly-diagnosed-diabetics.17088/
The diet doctor website is also very helpful and includes plenty of information for vegetarians.
For the diarrhoea, if you’re not on blood glucose lowering medication - and it sounds like you’re not, then it won’t be a problem if you don’t eat for a short period while things settle down, but it is very important to stay hydrated.
Finally a blood glucose meter would be a good idea. Tagging
@Rachox for some information.
Please do contact your GP and let us know how you get on.
