In theory no unless you bolus extra for the snack, if you inject the correct dose for the the previous meal and your basal insulin is right then a snack (depending what it contains) would push bg up.
I don't snack between meals and only do so if my bg starts to fall, if I were to snack then I would need to inject a unit of novorapid to stop my bg climbing, I prefer not to inject inbetween meals as it can become tricky to monitor when your stacking insulin doses.
Before diagnosis I didn't used to snack but since I started insulin I'm constantly starving. I stick to slices of ham or a pepperami or a piece of cheese or a small handful of nuts. Things that shouldn't cause a BG spike
I personally dont see any harm at all in diabetics eating a snack mid morning or mid afternoon if they want to. Before using a pump and using MDI and twice daily, I always had a small snack in order to keep my bg levels levelled out. I often eat a snack now if I need to or want to. I would not like to bolus every time to eat a snack, that's for sure but everyone's different... some are very busy and some are not.
I think it's ok to have snacks so long as they are less than 15g in carbs. My favourite snacks are breadsticks with Philadelphia, rice cake, water biscuits or a small packet of crisps my doctor told me that novarapid insulin has a fast effect and you can't inject for a later snack as the effect of the insulin will wear off and you don't want to inject too much and go into hypo
Personally, I take Lantus and NovoRapid. I don't need to inject extra insulin for snacks and I keep them under 19g of sugar. I do not experience any spikes.
