Type 1 or 2???

Hi everyone. My sister was recently diagnosed with diabetes. She was put on Metformin. For the past couple of weeks, she has been having horrible nausea and not feeling very hungry. Today she went to see the nurse at her surgery and was told she could be type 1 and not type 2 as originally told. She is having blood tests done ASAP and was told she might most likely will have to have an evening jab. The nurse said she could be onset type 1....can anyone help me give her advice or anything really?

this is a link to one source of information on LADA diabetes


If there is a strong family history of diabetes then it could be a MODY variant


MODY is a dominant gene which means that if you inherit the gene from one of your parents you will develop the diabetes - there are subtypes and some have a very low impact with the result that they can actually be controlled through diet and exercise as with type 2 but in general MODY is much closer to type 1 as it is the result of a decrease in the ability of the pancreas to produce insulin, which means it responds better to different medications than type

This link gives more information on the side-effects of metformin and their reported incidence


Must confess to being a bit surprised to see incidence of B12 deficiency listed in the very rare section though as I've read other articles and research that implies that it seems to affect B12 absorption in 40% of users - but that is an effect that would have required several years of use.

Tendency is to assume that diabetes developing in older patients is type 2 (insulin resistance) - however that isn't always the case - indicators that it is probably a type 1 would include a strong family history of diabetes, and the patient not being overweight or having a diet that is low in refined carbohydrates such as sugar, and heavily processed foods.


Thanks for that message Gambit62 il definitely look into the link
