[the Dawn Or Somogyi Phenomenon? High Morning Fasting Blood Sugar Values In Young Type-1 Diabetics].
Abstract High blood sugar levels in the morning in juvenile type 1 diabetics may be caused by a Somogyi phenomenon (counter-regulation after nocturnal hypoglycaemia) or insulin resistance in the morning hours (dawn phenomenon). To enable differentiation between the two, 1,562 blood sugar profiles (24 h, 3 h, 6 h) were determined in 161 children and juveniles (74 boys, 87 girls; mean age 10.8 [1.0-19.7] years) with type 1 diabetes mellitus. In accordance with the mechanism of the dawn phenomenon there was a close positive correlation between the blood sugar levels in the night and morning (r = +0.696; P less than 0.0001); the mean fasting blood sugar level was about 60 mg/dl above the 3 h value. Low nocturnal blood sugar levels as a possible cause of a high morning blood sugar (greater than 250 mg/dl) was demonstrated in fewer than 1% of profiles. On the other hand, the probability of nocturnal hypoglycaemia rose exponentially in the presence of low morning fasting blood sugar levels. Thus, if the morning level was below 80 mg/dl, the blood sugar levels at 3 h was below 50 mg/dl in 41.2%. This indicates that high morning blood sugar levels result from the dawn phenomenon and require a higher evening dose of slow-release insulin. But if the morning blood sugar values are clearly below 100 mg/dl, the cause may be nocturnal low blood sugar levels and the evening insulin dose should, therefore, be reduced. Continue reading >>
When To Test Blood Sugar In Type 2
One of the topics that comes up a lot in the email I get from visitors to my What They Don't Tell You About Diabetes web site is the question of when is the best time to test your blood sugar. A lot of doctors still tell people with Type 2 to test first thing in the morning and before meals. That was what I was told at diagnosis in 1998. People who test using this schedule may tell you their blood sugar is usually 120 mg/dl, which sounds pretty good, except that since this is a fasting number it usually hides the information that the person's blood sugar maybe going to 250 mg/dl or higher after every meal. Research has shown that for people with Type 2 diabetes--especially those who have been diagnosed recently and still retain some beta cell function--it is the high spikes after meals that contribute most heavily to raising the A1c and causing complications. If you only test your fasting blood sugar, you will not know anything about how high your blood sugar is spiking after meals, so you won't know which foods are toxic to you because they cause dangerous spikes. If you are like most people with Type 2 your access to the very expensive blood sugar testing strips is limited. You may have to pay for strips yourself or your insurance may pay for a single box each month. That means that you need to use each strip as efficiently as possible. Here are some strategies that you can use to get the information out of your blood tests that will let you drop your A1c back into the healthy zone. Keep a written log that matches what you eat with the test result you get. Even though your meter may keep a list of your readings, these readings are meaningless unless you know what food you ate that resulted in each particular reading. If you write down what portion size of which food y Continue reading >>

Fasting means not eating or drinking anything aside from water, for at least 8 hours before the testing. It shows the most reliable results of blood glucose. When fasting, the body triggers the production of Glucagon. Glucagon makes the liver metabolize glycogen (the type of sugar reserve supply in the liver) which is released into the bloodstream as sugar. This happens in normal people, not suffering from diabetes. In people with diabetes, something in the aforementioned chain-reaction does not work properly, so we get high levels of blood sugar building up in the bloodstream.

Unexplained High Blood Sugars
Member T1 with previous gestational diabetes Hello everyone. I've had diabetes for a few years now and take insulin to control it. Over the past couple of months my sugars have risen dramatically, completely out of control and I'm very worried. It is due to the high sugars in the past that my eyesight is failing so I don't want it to get any worse. But it dosn't seem to matter what I do, take more exercise, take extra insulin, reduce my carbs etc, I wake in the mornings with sky high sugars. I have tried to contact my diabetic nurse for advice but she is constantly unavailable so I feel very alone. Has anyone else had to deal with the same problem? How did you rectify it? Many thanks. Stress. For me, if I have a stressful situation my sugar skyrockets. This makes me more stressed, which makes it skyrocket more. Because my sugar is so high I feel crummy and don't excersize. You see the pattern here right? Maybe this isn't your problem, but if it is you need to excersize no matter how crummy you feel. NOt just a walk around the block or something lame like that but really work and get sweaty and tired and keep going. Do this for a few days and no only will you work the stress out of your system but your sugars will come back into line. I think it has something to do with human 'fight or flight' mechanism, where the liver (i think thats the organ that does it) dumps sugar into the blood times of stress to quickly supply muscles with energy. If you don't use up that sugar somehow your sugar skyrockets. Also if you stay stressed the liver keeps dumping sugar, and you can just pour in the insulin and your liver will keep on dumping more sugar to compensate. Happens to me all the time, I hate it, I know how to combat it, but unfortunately I'm not wealthy enough to just play o Continue reading >>
High Blood Sugar Symptoms
If you’ve had diabetes for any length of time at all, you’ve probably seen lists of the signs and symptoms of high blood glucose dozens of times. Doctors and diabetes educators hand them out. Hundreds of websites reprint them. Most diabetes books list them. You likely know some of the items on the list by heart: thirst, frequent urination, blurry vision, slow healing of cuts, and more. But have you ever stopped to wonder why these symptoms occur? How does high blood glucose cause frequent urination, make your vision go blurry, or cause all of those other things to happen? Here are some answers to explain what’s going on in your body when you have high blood glucose. Setting the stage for high blood glucose High blood glucose (called hyperglycemia by medical professionals) is the defining characteristic of all types of diabetes. It happens when the body can no longer maintain a normal blood glucose level, either because the pancreas is no longer making enough insulin, or because the body’s cells have become so resistant to insulin that the pancreas cannot keep up, and glucose is accumulating in the bloodstream rather than being moved into the cells. What is high blood sugar? Blood glucose is commonly considered too high if it is higher than 130 mg/dl before a meal or higher than 180 mg/dl two hours after the first bite of a meal. However, most of the signs and symptoms of high blood glucose don’t appear until the blood glucose level is higher than 250 mg/dl. Some of the symptoms have a rapid onset, while others require a long period of high blood glucose to set in. It’s important to note that individuals differ in their sensitivity to the effects of high blood glucose: Some people feel symptoms more quickly or more strongly than others. But each sign or sympt Continue reading >>
High Blood Sugar And Dizziness In The Morning
A high blood sugar level due to diabetes or other situations can cause a variety of symptoms such as dizziness, and it can even lead to blindness, nerve damage, heart disease and other chronic problems. Morning can be a common time for high blood sugar levels. Understanding what causes a spike in blood glucose and knowing what steps to take to lower it can help you to prevent complications. If your blood sugar level is high in the morning most of the time, it is important to speak with your physician. Video of the Day Your blood sugar level naturally fluctuates throughout the day. The foods you eat, your level of physical activity, stress, illnesses and medications can make your blood sugar levels rise and fall. In general, a normal fasting blood glucose level is below 100 mg/dL, the National Diabetes Education Program says. Once your level reaches between 100 mg/dL and 125 mg/dL, you may be diagnosed with prediabetes. If your level climbs over 125 mg/dL on more than one testing occasion, you may have diabetes. The medical term for a high level of blood sugar is hyperglycemia. Depending on the cause, it can take hours or days for your blood sugar levels to become so high that you develop symptoms. Symptoms of high blood sugar include not only dizziness but dry mouth, thirst, frequent urination, blurry vision, fatigue, confusion and increased appetite, University of Iowa Hospitals and Clinics reports. In general, the more severe your symptoms, the higher your blood sugar levels are. If you are having strong dizzy spells, seek medical attention. Both those with and without diabetes can experience "dawn phenomenon," and those with diabetes can experience the "Somogyi effect." During the early evening, insulin -- whether produced by the body or taken as medication -- works Continue reading >>
Healthy Snack Ideas For People With Type 2 Diabetes – Small Snacks
If you have type 2 diabetes, a snack can help you manage your blood glucose levels. If your Registered Dietitian suggests that a small snack fits into your diabetes meal plan, you’ll find many healthy ideas below. What is a healthy snack? Your snack choices should be based on the four food groups in Canada’s Food Guide. The amount of carbohydrate in your snack is very important since carbohydrate-rich foods make the biggest difference to blood glucose levels. Smaller snacks should have about 15 grams of carbohydrate. This is the amount found in one slice of bread or one small apple. Carbohydrates are also found in sugary sweets like pastries, chocolate bars and candy. Because they are not very nutritious, they should be chosen less often, if at all. Here’s a good rule to remember when choosing carbohydrate-rich foods: Choose more vegetables, fruit, legumes and whole grains like oats, barley, brown rice and whole wheat. Choose fewer products that are made from sugar, white flour and white rice. The smaller snacks listed below have about 15 grams of carbohydrate each. They each have 85-150 calories. Mid-day snacks Your eating plan may include a snack in the morning or the mid-afternoon. Here are some delicious options. 1 slice whole grain bread with 10 mL (2 tsp) peanut butter 1 small orange and 175 mL (¾ cup) edamame (green soybeans in the pod) 250 mL (1 cup) latte, cappuccino, unsweetened cocoa or chai tea made with skim milk 250 mL (1 cup) cantaloupe with 125 mL (½ cup) low fat cottage cheese 15 baby carrots with 30 mL (2 tbsp) hummus On-the-go snacks These snacks can be left in your briefcase, knapsack, car or your desk drawer. They will come in handy when you have a very busy day and need to grab a quick snack. 2 whole grain rye crispbread crackers 1 single-s Continue reading >>
Ketone Testing: What You Need To Know
What are ketones? Why should you test for ketones? How do you test for ketones? And what should you do when you find ketones? What are ketones? Ketones are produced when the body burns fat for energy or fuel. They are also produced when you lose weight or if there is not enough insulin to help your body use sugar for energy. Without enough insulin, glucose builds up in the blood. Since the body is unable to use glucose for energy, it breaks down fat instead. When this occurs, ketones form in the blood and spill into the urine. These ketones can make you very sick. How can I test for ketones? You can test to see if your body is making any ketones by doing a simple urine test. There are several products available for ketone testing and they can be purchased, without a prescription, at your pharmacy. The test result can be negative, or show small, moderate, or large quantities of ketones. When should I test for ketones? Anytime your blood glucose is over 250 mg/dl for two tests in a row. When you are ill. Often illness, infections, or injuries will cause sudden high blood glucose and this is an especially important time to check for ketones. When you are planning to exercise and the blood glucose is over 250 mg/dl. If you are pregnant, you should test for ketones each morning before breakfast and any time the blood glucose is over 250 mg/dl. If ketones are positive, what does this mean? There are situations when you might have ketones without the blood glucose being too high. Positive ketones are not a problem when blood glucose levels are within range and you are trying to lose weight. It is a problem if blood glucose levels are high and left untreated. Untreated high blood glucose with positive ketones can lead to a life-threatening condition called diabetic ketoacidosis Continue reading >>
Blood Sugar: What Causes High Blood Sugar Levels In The Morning
There are two reasons why your blood sugar levels may be high in the morning – the dawn phenomenon and the Somogyi effect. 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: Your body has little need for insulin between about midnight and about 3:00 a.m. (a time when your body is sleeping most soundly). Any insulin taken in the evening causes blood sugar levels to drop sharply during this time. Then, between 3:00 a.m. and 8:00 a.m., your body starts churning out stored glucose (sugar) to prepare for the upcoming day as well as releases hormones that reduce the body's sensitivity to insulin. All of these events happen as your bedtime insulin dose is also wearing off. These events, taken together, cause your body's blood sugar levels to rise in the morning (at "dawn"). A second cause of high blood sugar levels in the morning might be due to the 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. There are two potential causes. In one scenario, your blood sugar may drop too low in the middle of the night and then your body releases 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. The other scenario is when your dose of long-acting insulin at bedtime is not enough and you wake up with a high morning blood sugar. How is it determined if the dawn phenomenon or Somogyi effect is causing the high blood sug Continue reading >>
Is There A 'safe' Blood Sugar Level?
What is the "safe" blood sugar level? I have heard several opinions from other diabetics, and I am very confused. I was told that it was 154 about a year ago, and my doctor didn't recommend daily monitoring. At one time on a morning fasting, my level was 74. — Theresa, Alabama Yes, there is a safe blood sugar level. It is the optimum range that safely provides the body with adequate amounts of energy. For the average person, it is 70 to 105 mg/dl in a fasting state. (Diabetes is diagnosed when the fasting blood glucose level is at or above 126 mg/dl.) Glucose values vary depending on the time of day, your activity level, and your diet. Your sugar level of 154 mg/dl, which is high, may not have been determined while you were fasting. If it had been, a physician would have repeated the test. Your doctor did, and your level was determined to be normal at 74 mg/dl. In this case, daily monitoring is probably not necessary. If your levels are elevated in the future, you will be diagnosed with diabetes. Treatment can include lifestyle modification, diet, and exercise. If these strategies are not adequate to control your blood glucose level, your physician may prescribe oral medicines or insulin. Having a laboratory examination during your yearly physical and maintaining a healthy lifestyle are adequate for now. Why is it important to keep your glucose level within a normal range? An excess of glucose in the bloodstream causes various chemical changes that lead to damage to our blood vessels, nerves, and cells. Each cell in the body has a function that requires energy, and this energy comes primarily from glucose. The energy allows you to perform various tasks, including talking and walking. It allows your heart to beat and your brain to produce chemicals and signals that hel Continue reading >>
Blood Sugar Levels
In diabetics, dangerous blood sugar levels can occur if oral drugs do not work or if the diabetes has not been diagnosed. Sometimes diabetics forget to take their oral tablets or insulin or are in a situation where they cannot or they even may be taking some medications, which adversely affect their sugar levels. At such times, their sugar levels can go very high or even low. Normal blood sugar levels read 70-100 mg per deciliter of blood. The sugar levels vary throughout the day: when you wake up in the morning your levels are low and when you eat a carbohydrate/sugar rich meal, levels can go up. If you experience the mid-morning slump, your sugar levels are probably low. The highest level is reached two hours after a meal. Hyperglycemia or high blood sugar levels in a diabetic start at 180 mg/dl. However, some people, especially those who have undiagnosed diabetes can have dangerous blood sugar levels in the range of over 250-800 mg/dl. It is not just a short time high level that is dangerous, but when high levels persist or are dangerously high, they can cause more problems and even lead to emergency situations. Dangerous levels can lead to: Coma Stroke Blindness Nerve damage Blood vessel damage Kidney disease DKA or diabetic ketoacidosis – more common in people with type 1 diabetes Hyperglycemic hyperosmolar nonketotic syndrome (HHNS) – more common in people with type 2 diabetes. For diabetics, monitoring sugar levels are of utmost importance and can prevent dangerous complications. What Causes Dangerous Blood Sugar Levels? Blood sugar levels can go high in different situations and can be caused by: Not taking enough insulin Eating too much high sugar/carbohydrate foods Missing an insulin dose Less than usual exercise Drinking alcohol Stress Illness Injury Medic Continue reading >>

Is this good or bad? Aimee, Maldives Answer: Hello Aimee, Random glucose testing is important to distinguish how effective the treatment is. In diabetic people, the numbers for random glucose levels may vary widely. The comparison between days is not the right one. Take the random glucose test multiple times during a day and compare the numbers. In a diabetic person, they may vary more than in normal people but they must not vary too widely. If they do vary a lot this means that the treatment is not effective or your husband is not following it. The glucose levels must stay relatively stable as much as possible. Also, stress, diet and the time of the time may influence the results. It is important to contro Continue reading >>
Why Is Blood Sugar High In The Morning?
Here you'll find info about why blood sugar is high in the morning, along with tips and resources to lower those numbers! A while back I had a client sending me her blood sugar charts every few days and on those charts she always made some notes if she had questions. Every time she sent them through, I noticed she had 3 big question marks (???) against her morning blood sugar results. And on another morning when her morning blood sugar levels were high at 160 mg/dl (or 8.9 mmol/l). She had written: I don't understand. 97 mg/dl (or 5.5mmol/l) last night when I went to sleep. I didn't eat anything because I didn't feel well. Humm… I was also over in one of the online diabetes groups I'm involved in today and this message popped up. I'm struggling with my morning BS number. When I went to bed around 11PM my BS was 107. I'm waking up with my BS between 120 – 135. I did put two pieces of string cheese next to my bed and when I woke up around 3am, I ate one. Since I was told to eat protein at night. When I woke up 3 hours later my BS was 130. I didn't want to eat anything large since it's so close to 140 (my goal is to keep it below 140). So I had 1 piece of toast (sugar free wheat bread) and just a tiny bit of peanut butter. I checked it an hour later and it was 161! What am I doing wrong? Do these morning situations sound familiar to you? Are you constantly questioning: Why is blood sugar high in the morning? I mean, logically we'd think that it should be at it's lowest in the morning right? Well don't panic, there is a reason for it, so let's explore why morning blood sugar is often higher. And at the end, I'll also point you toward some resources to help you lower those levels. Why Is Blood Sugar High In The Morning?

I Have 250 Fasting Blood Sugar. What Should I Do To Control The Same?
An excellent question, but a complicated one to answer. Your doctor or nurse educator should be contacted any time your blood sugar runs consistently higher than 250 mg/dl for more than two days. When a person with Type 2 diabetes encounters a high blood sugar, the strategy used in bringing it down will vary from individual to individual. This is because of the differences in treatment concerning diet, exercise, and medication. It will also depend upon the guidelines for glucose control that you and your doctor have mutually agreed upon. When high blood sugars do occur, there are a number of strategies that can be employed to adjust the glucose level back down to a normal range. These might include: 1) Eating less food at the next meal, eliminating a snack and/or eating foods with a lower glycemic index. A general rule of thumb to follow is decreasing 15 grams of carbohydrate (the amount found in one starch exchange, one fruit exchange, or one cup skim milk exchange) will lower blood glucose by 30 mg/dl. If you test your blood sugar at 182 mg/dl before a meal or snack, then eliminate one starch and one cup milk at the next meal to bring the glucose value as close to 120 mg/dl as a baseline. Although people with diabetes will respond differently to this adjustment, it provides a basic guideline to start with. For persons with Type 2 diabetes who are overweight, the loss of only 5% to 10% of total weight loss can dramatically improve blood glucose values (so just cutting calories moderately can achieve better blood glucose control). Lastly, choosing foods with a lower glycemic index, i.e., foods that do not raise blood sugar as quickly or dramatically, can help to bring blood glucose back into a normal range. To test the glycemic effect of a food on your system, you will Continue reading >>
Type 2 Diabetes Diagnosis: 6 Months Later
NEW YORK I was sitting in my recliner watching TV on a sunny Sunday morning in June when my doctor called. I had been to see him that Friday for a checkup; he was passing on the alarming news that my blood glucose was over 300 mg/dL - about triple that of a healthy person. "Whatever you do, don't eat anything sweet," he warned, after we made plans to have me see an endocrinologist that week. After he hung up, I reviewed what I had eaten that morning: a latte from the French bakery down the street, along with a chocolate-almond croissant dusted in powdered sugar with two seams of rich dark chocolate inside. I had also polished off a pair of half-empty sorbet cartons in my freezer -- you know, to clear the decks for the coming week. Sugar was pretty much all I had eaten that morning. I spent the rest of the day googling the obvious likelihood that I had probably joined the ranks of 25.8 million Americans with diabetes. That's 8.3 percent of the U.S. population, according to the American Diabetes Association, and an estimated 7 million of those people don't even realize they have the disease. The ADA estimates another 79 million Americans are pre-diabetic -- which means they're well on their way to joining the club if they don't make lifestyle changes. Taken together, that's more than 30 percent of the U.S. population that is diabetic, undiagnosed, or pre-diabetic, according to the ADA. When I saw the endocrinologist two sugarless days later, my blood glucose was at 250 mg/dL -- still way too high. Another test of long-term control of blood glucose levels also had super-high levels. A normal blood glucose ranges from 70 to 130 mg/dL before a meal to less than 180 mg/dL after a meal, according to ADA. It was official: I was a Type 2 diabetic. My new endocrinologist gave me Continue reading >>
