Why Fasting Sugar Is Higher Than Pp
Fasting sugar higher than postprandial levels is termed as fasting hyperglycaemia. Fasting blood glucose level is determined by the insulin secretion, and whether the body is responding to it. PP sugar level is measured after the meal, hence it depends on the meal and our metabolism.
Generally, fasting sugar is lower than pp. But if this scenario is reversed, then it means that the body is not producing enough insulin, or not responding to it properly. This could be a sign of a serious health issue and in such a situation, the person should contact a doctor.
Symptoms Of High Blood Sugar Levels In Morning
In the morning, a persons blood sugar levels are generally somewhat higher. However, in certain persons with diabetes, these levels are considerably high.
Symptoms of diabetes can continue for long periods.
Carbohydrate-induced blood sugar imbalances may lead to a wide range of symptoms. These might get worse as time goes on, as a result of these blood sugar spikes.
Healthy blood sugar levels are defined as follows by the National Institute of Diabetes and Digestive and Kidney Diseases:
- Just before eating, from 80130 mg/dl 2 hours after eating, and below 180 mg/dl 2 hours following a meal.
- Furthermore, they observe that a blood sugar level of less than 70 mg/dl is hypoglycemia. A high blood sugar level is defined as anything over 180 mg/dL.
The dawn phenomenon, the Somogyi effect, and Waning insulin are the three primary causes of elevated blood sugar in the morning.
This article explores these causes. It will also include what they can mean for a persons health and when to see a doctor.
Techniques To Manage Your Blood Sugar In The Morning
Based on your glucose levels and trends, there are a few things you can do to manage your glucose levels so they dont run high in the morning. Some of these strategies focus on adjusting medications to better suit your needs. Other strategies include adjusting your exercise routine, as well as what and when you are eating before bed.
If your glucose levels are in range before bed, they may rise throughout the night without enough insulin. This can be especially true for people who take long-acting insulin in the morning, since it may be wearing off before your next dose.
Consider changing the time of day when you take your long-acting insulin. You may also benefit from switching to either twice-daily basal insulin or ultra-long-acting insulin, or from starting on an insulin pump. Read our article, Are You on the Right Kind of Insulin, to learn more.
Check your blood glucose during the night between 3 am and 8 am. If you are running high during these hours, you may be experiencing the dawn phenomenon.
Talk with your healthcare team about finding the best nighttime insulin regimen for you. If you take basal insulin, you may need to delay the timing of your dose to as close to bedtime as possible. Another option is to try an insulin pump or automated insulin delivery system. AID systems will automatically adjust your basal insulin doses throughout the night to help keep your glucose levels stable.

Pinpointing The Cause For Effective Treatment
Its important to understand whats causing your morning hyperglycemia before your doctor can treat you. To pinpoint which of the three reasons is behind your high numbers, check and record your blood glucose before you go to bed, at 3 a.m., and then first thing in the morning. Although it isnt fun to set a middle-of-the-night alarm, continue to do so for a few nights in a row.
If your blood sugar is fairly even when you go to bed and at 3 a.m. but is higher in the morning, you are probably experiencing dawn phenomenon. If your blood sugar is low at 3 a.m., but high in the morning, you probably suffer from the Somogyi effect. If your blood sugar is elevated at 3 a.m. and then higher still in the morning, you probably have waning insulin.
Even if youve identified the reason behind your high morning number, never attempt to correct it on your own. Instead, talk with your doctor. Together, you can find a treatment plan that gets you back on track in the morning.

Signs Of High Blood Sugar In The Morning
High blood sugar is significant when its too high. Thats when its called hyperglycemia. Hyperglycemia is usually defined as above 126 mg/dL or 7.0 mmol/L in a period of fasting . This will be the clearest sign of high blood sugar in the morning.
Before breakfast, you usually would have had a period of at least eight hours without eating . As such, hyperglycemia during a period of fasting is particularly important here: youll know that the high blood sugar wasnt caused by any recent meals.
Other signs of high blood sugar in the morning will be the usual symptoms of hyperglycemia:
- Increased urination
Of course, its normal to feel somewhat groggy and thirsty when waking. Its important to distinguish between hyperglycemia and the I-hate-Mondays morning tiredness. And the best way to do that is to test your blood sugar.
What Is The Normal Range For Blood Sugar Levels And What Blood Sugar Level Constitutes A True Emergency
Dr. Horton answers the question: ‘Normal Range For Blood Sugar Levels?’
& #151 — Question:What is the normal range for blood sugar levels, and what blood sugar level constitutes a true emergency?
Answer:Now, in a normal individual we measure blood sugar under different circumstances. What we call fasting blood sugar or blood glucose levels is usually done six to eight hours after the last meal. So it’s most commonly done before breakfast in the morning and the normal range there is 70 to 100 milligrams per deciliter.
Now when you eat a meal, blood sugar generally rises and in a normal individual it usually does not get above a 135 to 140 milligrams per deciliter. So there is a fairly narrow range of blood sugar throughout the entire day.
Now in our diabetic patients we see both low blood sugar levels that we call hypoglycemia, or elevated blood sugars, hyperglycemia. Now, if the blood sugar drops below about 60 or 65 milligrams per deciliter, people will generally get symptoms, which are some shakiness, feeling of hunger, maybe a little racing of the heart and they will usually be trenchant or if they eat something, it goes away right away. But if blood sugar drops below 50 and can get down as low as 40 or 30 or even 20, then there is a progressive loss of mental function and eventually unconsciousness and seizures. And of course that is very dangerous and a medical emergency.

Surprising Things That Can Spike Your Blood Sugar
When you first found out you had diabetes, you tested your blood sugar often. Doing so helped you understand how food, activity, stress, and illness could affect your blood sugar levels. By now, youve got it figured out for the most part. But thenbam! Something makes your blood sugar zoom up. You try to adjust it with food or activity or insulin, and it dips really low. Youre on a roller coaster no one with diabetes wants to ride.
Do you know all these blood sugar triggers?
Knowledge is power! Look out for these surprising triggers that can send your blood sugar soaring:
A Good Nights Sleep Can Help Control Morning Blood Sugar Levels
Experts recommend 6-9 hours per night, as poor sleep can aggravate insulin resistance and contribute to high blood sugar levels.
If you snore or wake up feeling unrested, talk to your doctor or your diabetes management team. You may have a condition called sleep apnoea , caused by your airway becoming partially blocked while you sleep. Sleep apnoea causes oxygen levels in the body to fall, which in turn causes some hormonal changes that lead to impaired glucose control. Sleep apnoea is a risk factor for type 2 diabetes, and type 2 diabetes is a risk factor for sleep apnoea .

What Causes High Blood Sugar Levels In Morning
The majority of the time, your bodys natural hormonal changes in the morning raise blood sugar levels, whether you have diabetes or not. Your body just produces more insulin to bring everything back into balance. You wont realize its happening.
However, if you have diabetes, things are a bit more complicated. Even though you follow a nutritious diet. Your fasting blood sugar level might rise even if you dont take insulin properly.
The sugar surge is your bodys method of making sure you have the energy to get out of bed and begin your day. If you have diabetes, your body may not be producing enough insulin to counteract these hormones. This disrupts the delicate equilibrium that you work so hard to maintain. This further causes your blood sugar levels to be excessively high by morning.
Blood Sugar And Sleep
A lot goes on in your body while youâre sleeping. Aside from dreaming, memory formation, muscle repair, and other functions, your body actively manages glucose during your slumber.
In a healthy human, itâs normal for blood sugar to fall a couple of hours after their last meal and remain on the low end of healthy fasted blood sugarâhealthy being 72 to 100 mg/dLâuntil early morning. Your body doesnât require as much energy to perform basic functions at night, thus it doesnât require as much circulating glucose or as much of the hormone insulin.

Build A Clear Picture Of How Your Blood Sugar Works By Using A Cgm
As weve seen, everyones blood sugar control works differently, so it can be helpful to know whether morning spikes are a problem for you.
Unless you have diabetes, it is unlikely that you check your glucose regularly.
Checking your glucose a few times throughout the day or continuously via CGM can help to show how your body is handling changes in glucose levels during fasting or after meals.
Why Is The Blood Sugar High Despite Taking Medication
Most medications to take in the morning forces your body to make insulin. So agents like glipizide produce insulin that helps with your meals. But then it wears off. And then at night your body still needs insulin. So insulin is not just necessary for the food, but also your body needs insulin even during fasting. Therefore, even if youre eating no carbs whatsoever you still need insulin. In the relative deficiency or resistance to insulin, a lot of patients will end up waking up with high blood sugars especially if the medications they take wears off by the time they go to bed.

Is The Dawn Phenomenon Something I Need To Fix
The dawn phenomenon isnât necessarily something that needs to be fixed though you might be able to reduce its effect. Itâs important to keep in mind that even though your fasting glucose may be elevated, you may have lower or normal glucose values throughout the rest of the day.
Itâs not uncommon for people reversing their diabetes through nutritional ketosis to experience the dawn phenomenon and still see improvements in their HbA1c. Why? Because HbA1c is a measure of your average blood glucose over the last 3 months. The average value matters more than any individual blood glucose value.
Here’s an example blood glucose curve of someone controlling their type 2 diabetes through nutritional ketosis who experiences the dawn phenomenonÂ²:
Wait Why Is Your Blood Sugar Up In The Morning
Why is it that your blood sugar levels will rise overnight? You dont eat anything, so how can you possibly add any glucose to your system?
Well, those who suffer from type II diabetes will find this is most problematic. The body still creates glucose throughout the night. It needs to, whether youve eaten something or not. This natural process is called gluconeogenesis, and there is nothing you can do to stop it nor would you want to. In a healthy person, this process doesnt cause a major problem.
Those with diabetes will find the gluconeogenesis process is increased. That means your body produces more glucose naturally than it would if you were healthy.
Lets not forget that the stress hormone cortisol also plays a part. This increases slowly on a morning until it reaches a peak early in the morning. The cortisol will elevate the blood sugar levels, so you end up with naturally higher levels on a morning.
To keep your blood sugar levels down, you need to keep your cortisol and gluconeogenesis levels down. Theres no need for extra medication when you follow the seven tips that will follow.

How To Prevent High Morning Blood Sugar
Do not fret, friends. There are ways to deal. Here are three simple ways:
1) Take insulin right when you wake up
If its 2 pm and you notice your blood sugar is shooting up for no apparent reason, youd take a correction dose of insulin to prevent that spike, right? .
The same concept applies here.
To determine how much insulin to take, wake up, record blood sugar values at 30 and 60-minute intervals, and record this for a few days . Then, you can use your insulin to carb ratio to determine a correction bolus.
2) Increase your basal rate around your wake up time
If you fight Dawn Phenomenon, whats a common strategy for success? Increasing basal rates in the wee hours of the morning to counteract that hormone-induced spike.
Well, if youre used to a particular morning routine and know itll take you a little while to prepare food and eat, consider increasing that basal rate during that time period. That additional insulin may overcome the liver dumping glucose and blunt your blood sugar spike, or ideally, prevent it in the first place.
3) If you skip breakfast, stop skipping it and EAT SOMETHING
As a registered dietitian, I can regurgitate all the information from the Academy of Nutrition and Dietetics about why breakfast is important. This isnt about that, but in all honesty here, try eating SOMETHING. Id love if it were healthy, but if youre just DYING to have Cinnamon Toast Crunch, by all means, have at it. If youre about the low-carb life, go for some eggs.
High Blood Sugar Levels In The Morning
People usually have slightly higher blood sugar levels in the morning. However, in some people with diabetes, these levels can be significantly higher.
Diabetes is a condition that impairs the bodys ability to process blood glucose. Without careful management, blood sugar levels can become too high, which is known as hyperglycemia. Long periods of high blood sugar levels can result in health complications.
Even when a person carefully controls the condition, they may notice blood sugar spikes in the morning. There are three main causes of high blood sugar in the morning:
- the Somogyi effect
It is important to note that this article refers to effects experienced in the morning, but these effects may occur anytime a person sleeps for a long period. People who work at night and sleep during the day can also experience these effects.
In this article, we will explore these causes, including what they can mean for a persons health and when to see a doctor.
dawn phenomenon refers to periods of hyperglycemia that occur during the early morning hours. The shift in blood sugar levels happens as a result of hormonal changes in the body.
Hormones, such as cortisol, glucagon, epinephrine, and growth hormone are known as counter-regulatory hormones. They can cause blood sugar levels to rise. The activity of cortisol and growth hormone normally increases each day to stimulate the liver to produce glucose at dawn.
