Any idea what's going on?

Hi, I was diagnosed with type 2 in 2015 hba1c 143. Initially diet controlled, (low carb)started taking Metformin in 2020 because hba1c never went below 61. I never lost weight even though I ate a low carb diet. GP agreed to test C peptide level which was 1900 at the time.
In October 2024 GP prescribed Rybelsus and advised me to eat some carbohydrates. I started to have 2 slices of toast with butter every morning for breakfast. Stayed low carb for lunch and dinner. Gained 8lbs and hba1c went from 51 to 63 in about 6 months to mid Jan. GP repeated C peptide test result is 1852pmol/L and agreed that I could stop taking Rybelsus.
I have cut out the toast and have been low carb since mid Jan. Started testing on Monday and fasting level has been high since then (around 20mmol/L.) This morning my fasting level was 17.0 so I tried oat bran porridge made from 30g oat bran and whole milk. 2 hrs later 24.9mmol/L.
I'm having a review with the practice nurse on 9th March and I don't know what to ask her.
I'm sorry for the long post but I have tried so hard for years and nothing seems to change.
I really don't know what to

Hi @Swiggy , I'm sorry to hear you are struggling.

I have cut out the toast and have been low carb since mid Jan. Started testing on Monday and fasting level has been high since then (around 20mmol/L.) This morning my fasting level was 17.0 so I tried oat bran porridge made from 30g oat bran and whole milk. 2 hrs later 24.9mmol/L.

Oat bran has about 50 grams of carbs per 100 grams so your breakfast had a significant amount of carbs with the milk added. Have you considered a low carb breakfast? (Bacon and eggs, natural Greek yoghurt with nuts or such?)
Your fasting levels are quite high.
Can you contact the diabetes nurse before your appointment to let them know your findings?
Something isn't going right.
