Why are my blood sugar levels so high in the morning?

I have been a diabetic for the past 6 years. Lately, I've noticed my blood sugar levels are very high in the morning. What could be the reason for this?

Sugars are high in the morning because chemicals in your body released over night act on stored complex sugars which release glucose to increase the level of glucose in the absence of food.

Blood glucose levels in the morning are influenced by the meal composition and the timing of meals consumed after 4 PM the day before. Consuming the bulk of one's daily calories after 4 PM and favoring starchy foods (potato, corn) will result in higher glucose results the morning after. Also, patients taking medications for diabetes may experience hypoglycemia overnight resulting in high morning glucose results. Bear in mind that the body produces hormones such as cortisol that peak in the morning and that naturally raise the blood glucose, but our diet and lifestyle (sleep) can aggravate this tendency
There is a thing called the dawn phenomenon. Every morning in all of us the glucose levels increase because other hormones rise (growth hormone, adrenaline, cortisone) but so does the insulin. When the insulin levels are that as high and there is a deficiency the glucose Best Dr. Norwood
Dear patient:

Dear Patient:

elevated sugars in the morning on awakening are usually due to insulin resistance causing the liver to make large amounts of sugars overnight; it may also be due to eating large dinners late at night usually after 8 pm. Another reason could be nocuturnal hypoglycemia with morning rebound hyperglycemia.thought to be due to too much insulin at night prior to sleep.
You need to keep careful records of food intake, time of eating, blood sugars,time when taking meds for diabetes and then of course carefully discuss with your physician to make changes in your treatment regimen.

First morning blood sugars can be elevated for several reasons. A common reason is that sugars are high at bedtime the prior evening and remain above normal throughout the night, usually due to inadequate insulin coverage of the dinner meal and evening/bedtime snacks. Other common reasons include stresses during the night, such as pain, insomnia, frequent nocturia or frequent awakening for any reason, acute infection and some steroid regimens. Growth hormone is higher in the morning, as well, and in the setting of inadequate insulin, could lead to higher morning blood sugars ("dawn phenomenon"). Elevated morning sugars once were thought to result from rebound from nocturnal hypoglycemia ("Somogyi effect"), but this notion has been discredited.
Your body makes too much glucose overnight. Normally there are hormones made by your pancreas that make your liver make sugar overnight when one is starving. Patients with diabetes make too much sugar overnight because of excess glucagong and too little insulin
Yes there is a reason for it. It is called the "Dawn Phenomena" and was first described by a physician Jack Garrich at the Mayo Clinic several years ago. It is due to the production of hormones in the early hours that raise blood sugar. We all produce these hormones (growth hormone & cortisone) sometime in the night or morning (I am a night creature So I don't produce mine until 8 0r 9 0'clock in the morning & like to sleep until 9 or 10 AM. Most people though are not lazy like me & secrete these hormones at 4-6 AM. They are our wake up & get going stimuli & that's good but these hormones are what are called counter-regulatory hormones i.e. they raise blood sugar. So if you secrete a large amount of them in your dawn wake up they can raise blood sugar to high levels in the morning. I don't know what medicines you are on but you need to take some long acting meds probably at bed time to cover the time of the problem. If you are taking insulin & with this problem you would be a candidate for one of the new ultra long acting insulins such as Tresiba (lasts 42 hours) or Toujeo (lasts 36 hours) so the overlap will help with the Dawn Phenomena. Talk about this with your Dr ro find the rig
There is a hormone that by nature is high in the mornings, and it is called CORTISOL. This hormone elevates the blood glucose. It is also referred to as "The Dawn Phenomenon."
