Blown away by readings after a Meal

Okay so I slept in and took my BG before I ate anything, it was 270, then I had a cup of coffee with whitener, no sugar and some whole wheat Life cereal with milk , no sugar added. I also took 500 mg Metformin and one hour later it went up to 480. I am shocked. Does that happen every time I eat something?

I am not surprised by your experience. I found out several years ago that I could not eat any cereal for breakfast, nor drink any milk if I wanted to keep my BG from spiking. . I now have 1 slice of whole wheat toast with one dry fried egg, eaten with plain water and coffee, and usually a banana. This with 1000mg Metformin and other supplements. Milk is what I use in the night when my Lantus takes me too low… Milk will quickly raise BG, just like fruit juice, but will last a bit longer.

My highest yesterday was a 308 and it was a cabbGe roll. I think it just raises once n a while though like that. Today mine was back to normal

Go for protein versus cereal. Eggs are good with whole wheat toast.

Any carbohydrates will spike you. That cereal and milk was probably about 40 carbs, which is hefty and will raise your BG significantly. However 2 eggs and toast is closer to 15 and won't impact BG nearly as much.

For breakfast I eat an egg and low carb yogurt. About 10 carbs. Lots of protein so I'm full- without the filler of flour.

How bad is a spike if it goes down after a few hours? Does it damage me if it goes
up for an hour. What can I eat for breakfast that won't spike me? What about skipping breakfast, does that cause problems?

Everyone spikes, diabetic or not. Usually, it takes about 2-3 hours to come back down depending on the meal. Skipping meals, especially breakfast isn’t an option, because you then run the risk of “Dawn Phenomenon” (because it usually happens in the morning after you’ve gone a long period without food) or less attractively “liver dump” – which is yet another spike. This is your body’s way of keeping you alive - your liver dumps stored glucose into your system to keep you from going too low.

Lessening these spikes, and avoiding the liver dumps are what we’re after. Keeping your meals lower carb and smaller portions helps, and keeping meals small enough that you’re hungry for a snack in another 3-4 hours helps even more. Smaller meals every 4 hours or so keeps the spikes down and the liver happy.

Damage occurs when we tax our pancreas and livers asking them to perform above and beyond what they were designed to do (high and low spikes), not unlike your heart. Reasonable meals, and a slow, steady feeding through the day allows them to operate at a more comfortable level. It’s also thought that they have some ability (in T2’s) to self-repair past damage, and even though your numbers are out of whack now, getting them in line and giving Mr. Pancreas a break can leave you functioning “normally” after a while.

As Harlen and James mention, it was the carbs. Your meal was mainly carbs with not much protein.
Using James' testing, testing and more testing methods I have learned cereal (whether wheat, oats, corn, or rice) makes my BG spike. If I try some with enough protein, like nuts, I get a smaller spike. For my BG to get lower spikes I usually try for a ratio of no more than 2 grams carbs to 1 gram protein.
When I am testing a food or meal, I check my BG before eating. Then again right after eating, and for the next two to three hours every 15 minutes. Others check their BG every 30 minutes. I do it more frequently because it gives me a better idea of what is going on.
There are many foods and meals I have found with this method that only give me a 10-30 point rise during the three hours. And found those that make me decide they are nit worth the BG spike.

Howdy LouAnn.
Yes one's Blood Glucose (BG) rises after one eats.

How much it rises depends on what and how much is eaten. If one eats carbohydrates one will get a faster and higher rise in their BG levels. Eating protein the BG will rise, but not as fast and not as high as it takes a longer time to digest it.

Harlen is right in that cereal has a lot of carbs. The majority of the carbs in most cereals are simple carbs, which digests quickly and raises BG levels quickly. Take a look at the nutrition information for regular Life cereal (the closest to whole wheat Life I could find):

For a serving size of 3/4 c. without milk, the calorie count is 120 and the carbs are 16. (To add milk to the cereal would add to the carb and the calorie counts depending on what type of milk was used.) for the whole nutrition label see here ~

Generally speaking the postprandial (after eating) BG levels are taken 2 hrs following your first bite of food. It gives us a better look at the effects of a particular food on the body.

This may be a good time to discover how your metabolic reaction to particular foods affects your BG levels. I have learned that not everyone reacts the same way the same food or drink so it would be important to find out what plays nice with your metabolism and what does not.

I had written up a way of discovering how certain foods or drinks affect your BG levels. Please take a look at the discussion here ~

I have a 3 ring binder with pages containing how certain foods affect my metabolism. Perhaps you might want to do something similar.

What a great idea James to keep a binder with information on how various foods affect your blood sugar levels. Carbohydrate intake is the major player in blood sugar levels, and we also want to consider exercise and physical activity as well as stress levels. LadyLouAnn, you're getting excellent information and I encourage you to keep track of your blood sugar levels and discuss what you're finding with your physician as well. ~Lynn @Glucerna

Wow! Metformin doesn't lower your bs. Insulin does. I was told to test two hours after eating when i don't take insulin. Curious to see what bs is in another hour. Where did u find whole wheat life cereal? I have never seen it
