Morning High Blood Sugar Levels
Louise_WebMD_Staff posted:
Morning High Blood Sugar Levels

Dawn phenomenon
. The dawn phenomenon is the end result of a combination of natural body changes that occur during the sleep cycle and can be explained as follows. Between 3:00 a.m. and 8:00 a.m., your body starts to increase the amounts of counter-regulatory hormones (Growth hormone, cortisol, and catecholamines). These hormones work against insulin's action to drop blood sugars. The increased release of these hormones, at a time when bedtime insulin is wearing out, results in an increase in blood sugars. These combined events cause your body's blood sugar levels to rise in the morning.

Somogyi effect. Named after the doctor who first wrote about it, this condition is also called "rebound hyperglycemia." Although the cascade of events and end result -- high blood sugar levels in the morning -- is the same as in the dawn phenomenon, the cause is more "man-made" (a result of poor diabetes management) in the Somogyi effect. The term refers to pattern of high morning sugars preceded by an episode of asymptomatic (without symptoms) hypoglycemia. Your blood sugar may drop too low in the middle of the night, so your body counters by releasing hormones to raise the sugar levels. This could happen if you took too much insulin earlier or if you did not have enough of a bedtime snack.

This was the original question I asked when I arrived at the board - appreciate the answer!
rubystar2 replied to rebitzman's response:
Hmmm... I have some irregular sleeping patterns at best. What would that do to any Dawn Phenomenon and/or control of my diabetes if there is no real 8-10 hour stretch of sleep for me? I may sleep 5 hours in the morning and a couple more before I go in to work.
krhudson responded:
Great information Louise. Mistery solved about those morning high sugars. I noticed that when I get up the blood sugar may be a little low such as 70 or 75 and if I have a fasting blood sugar and A1C testing at the Lab things stay in tact pretty well since the medical clinic is near my neighborhood. When I get home from that at around 9:00 AM (2 hours after I wake up) I test before food and the sugar will have gone up in some cases to 140. This can happen really any morning, not just the test morning of course. I can be around 70 when just waking up and then I get ready for work and 1 hour later my sugar will have increased to 110. That would be part of the Dawn Phenomenon right even though awake for that hour or so? I am a type 1 on Lantus before bed with a snack and Humalog as need with meals. Thank you in advance for the answer.

ClovisLutz replied to krhudson's response:
High sugar or also known as having an excessive amount of glucose in the bloodstream can lead to many complications.To maintain an average and good levels of sugar going around and supporting the cells of your body, make it a point to check blood sugar by using a blood glucose meter or by making an appointment with your doctor.
krhudson replied to ClovisLutz's response:
Thank You for the advice Clovis. I was referring to Louise's post at the top of the page about Dawn Phenomenon and what goes on in the body to cause an uptick in Blood Sugar readings when within a period of time the sugar goes up for no apparent reason in the mornings for many diabetics and being a Type 1 diabetic I can adjust accordingly for it. Sometimes if the spike is reasonable and I am within 30 points where I need to be I just increase my fast acting insulin by .50 to .75 a unit. Got to be cautious not to overdo the night time insulin either. It is something I have dealt with for 35 year and mostly have it down to a science but it is a challenge. My Dr. sees me every 90 days for my A1Cs and of course I am on here to learn more from others. Type 1 and type 2s basically need to work on the same diets and excersise and overall concept of those darn high blood sugars and lifestyles to stay healthy.

Bedtime snack?! I was led to believe I should not eat after 8 PM. If I eat later than 8 my morning glucose is high (130-150).
Furthermore, I don't know what I'm supposed to eat: Twigs, bark and grass like most weight loss diets? Or some recipe that uses ingredients I've never heard of (Agave nectar, etc.?) and takes an hour or more to cook?
And what the heck is an exchange??? I was diagnosed with Type 2, non-insulin dependent diabetes in 2006 and I still don't understand it. I weigh 545 pounds and need help badly.
betatoo replied to billw64's response:
Bill try looking up glycemic index and load in relation to healthy eating. It may be the best place to start. At the same time, one of the best things I have done is to greatly up my vegetable intake over all else. I have eliminated the white starches, and cut way back on the orange and brown starches. Protein as in fish, chicken are my staples, but I do eat bacon and red meat on occasion. Portion control is helpful, but if you are hungry, you are hungry. Try cutting the hunger with veggies. Most microwaves have a frozen veggie setting. Try a bowl of these when the urge hits-broccoli, asparagus, cauliflower, peppers, etc. They will help.
