I didn’t bolus for the vegetable last night and only did it for the carbs, hence why there may have been a spike in my blood sugars in the morning.
As you put that question it is akin to asking how long is a piece of string! What, fairly exactly, was the spike? How big, how long after your 1st mouthful and for how many minutes did that spike prevail? Without those answers we don't really know if you even had a spike (as we would understand that) nor whether the apparent spike continued beyond the reasonable time that you had bolus insulin on board?
What I mean by that is first of all did you take a bolus just for your food or did you include an additional bolus component to correct a starting point higher than you wanted. Ifcyes was your correction ratio correct? Plus did you, after c. 4 or 5 hours, still end up higher than you wanted or was, in practice the spike eventually dissipated by the bolus? If it was eventually dissipated then was that because you took fairly urgent and unusual steps to cause that, eg by extra exercise or activity? So:
If the spike dissipated on its own then that suggests your bolus was correct in size of dose but the timing was wrong - the digested carbs arrived before your insulin and for that meal causing a spike and you should consider having a longer pre-bolus interval.
If exercise finally brought your spike down then you got a good result, but that may not be an acceptable routine for you overall (it may be too intrusive to your lifestyle). In this case your bolus needs increasing a little (how much depends on the carbs counted and the carb to insulin ratio).
If you simply ended the meal higher than you started and your bolus never gave you the reduction you sought, then your carb counting or your carb to insulin ratio needs reviewing. But don't rush to immediately change things - take note and when you repeat that set of circumstances (ie the same food with the same ratios and bolus doses) check to verify you get the same wrong result. Then make changes.
Metabolism is not a precise process and our bodies behave differently on different days, influenced by many, many different factors. The weather, your stress from the day, what exercise you have had during the day and the day (or 2) before, are just a few factors. Also carb counting is not a precise process; even when foods are accurately weighed and the carb content scrupulously read from a packet or book (with careful maths applied) this is still not really accurate. Carb counting is necessary but some pragmatism is needed about the final guestimate.
How much would you exactly bolus for broccoli and half a red bell pepper,
Personally I'd apply no extra bolus for those 2 vegetables. If my late mother had been the cook and stewed them into submission, then maybe I'd assume the fibres in the veg were breaking down and also being digested!! [Apologies to my late Mum] Fibre is pure carbohydrate, but is routinely ignored since fibre is not routinely digested by humans. (Cows have 4 stomachs to give them the best chance of getting some energy from grass - which is effectively pure fibre). But those 2 fresh veg moderately cooked would have no impact on my BG. That doesn't mean that this will definitely be the case for you or some other people.
I’m sure that covers one unit altogether dosent it, and what about for salmon, if you’re having that also, maybe cos I didn’t bolus for the salmon, could have also been the reason.
You are clutching at straws now. Salmon has no carbs. As I've tried to explain earlier we need to see the full picture to try and explain why you spiked.
But from what I know, you only bolus for the carbohydrates if you’re having protein also.
I have no idea where this concept has come from. If you are eating carbs, naked as icing sugar or smothered in protein or fat, pizzas and lasagnes, then those carbs should always be counted and insulin taken. Some complex meals, with carb digestion delayed by fats in particular, can get their transition into glucose delayed and reach your blood after the bolus insulin has been and gone. Now we are trying to turn you into a top equivalent of a sprinting hurdler - where its not just a case of getting a good time over a 100m sprint, but with every stride exactly right in length and each hurdle vaulted with no break in momentum and minimal disruption to the overall speed. So let's ignore this aspect of fatty food digestion speeds for now!
