It is generally the case although it is probably mainly due to what is known as the Dawn Phenomenon where the liver throws out some extra glucose to give us an energy boost for the day. It is believed to be a throwback to prehistoric days when we didn't have food in the fridge and cupboards and therefore we needed some energy to go out and hunt down a woolly mammoth for breakfast. Those of us who inject insulin tend to see that we don't respond to that insulin as effectively in the morning as we do during the rest of the day and hence it is considered insulin resistance but in reality it is probably this effect of our liver pumping out extra glucose to add to what we have actually consumed which means it doesn't drop our BG as we would normally expect at other times of the day and consequently we need to inject more insulin than usual for the carbs we have eaten. Even if we skip breakfast our glucose levels will rise by several full units as a result of DP if we don't inject insulin to cover it. I usually need 1.5-2 extra units of insulin for DP which is the equivalent of my BG rising by 4.5-6 mmols which means that if I woke up with a nice in range fasting reading of 5, DP can take my BG up to 10 without consuming any breakfast if I don't inject some insulin to cover it. Your BG is unlikely to rise by that much as you are Type 2 and your body will still be producing insulin but since most Type 2s are insulin resistant it will take longer for the body to clear it from the blood.
It is possible to see the effect for yourself by purchasing a Blood Glucose Meter and testing your blood when you first wake up and then an hour or so later without eating any breakfast and you will almost certainly see your levels rise.
Using a BG meter is highly recommended here on the forum if you are looking to control your diabetes via diet as it can give you invaluable information about how your body responds to particular foods. This can be highly individual due to differences in metabolism and gut biome and genetic factors, so whilst one Type 2 diabetic might get away with eating porridge for breakfast, it could be spiking someone else's BG and keeping it high for half the day. By testing before and then 2 hours after eating we can see how that food has impacted our BG levels and decide if it was a good choice or we need to reduce the portion size or perhaps avoid that food altogether.
The NHS no longer funds BG meters for all diabetics as funding is limited and many medical professionals are not aware of how beneficial they can be in helping people to control their diabetes and there is a concern that people will become obsessed.
Basic BG meters are relatively inexpensive to purchase (approx. £15) but the consumables like test strips and lancets are where the financial impact occurs. For that reason, here on the forum, if people are self funding, we recommend either the SD Gluco Navii BG meter or the Spirit Healthcare Tee2 meter as these have the cheapest test strips at £8 for a pot of 50 and whilst that seems like a lot, they disappear quite quickly when you are testing several times a day for the first few months until you build up a picture of how certain foods (and exercise) affects your levels.
Anyway, that hopefully answers your question, even if it is a bit long winded!
