Why Would You Have High Blood Sugar If You Have Not Eaten In 12 Hours?
When humans eat carbohydrates, the body converts them to sugar. The sugar fuels every cell in the human body, but it’s important that sugar levels be neither too high nor too low. Low blood sugar, called hypoglycemia, can cause brain damage and even shock. High blood sugar, known as hyperglycemia, is another matter. Video of the Day When you consume carbohydrates, the starches are digested in the small intestine. After entering the bloodstream, the starches, which have been converted into sugars during the digestion process, cause your blood sugar, or glucose, to rise. When the blood sugar increases, the pancreas secretes insulin. Insulin helps most tissues of the body absorb and use the sugar. Only the brain and liver are not dependent on insulin. Since prolonged hyperglycemia can damage body cells, insulin is used to keep the blood sugar within a fairly narrow range. As the blood sugar falls – for example, several hours after a meal when you are starting to get hungry again – the liver releases glucagon, which increases the blood sugar until it is back within the desired range. This seesaw effect goes on constantly in the body, and if your metabolism is healthy, no problems occur. Diabetes mellitus, usually known simply as diabetes, is a disease in which the process of glucose regulation is disrupted. The first problem occurs when the cells become more resistant to insulin. This is called metabolic syndrome and is often a precursor to full-fledged diabetes. Sometimes the pancreas can stop producing insulin suddenly; this is called type 1 diabetes. Or insulin production in the pancreas can slow down gradually – type 2 diabetes. The slowdown of insulin production and a decrease in the cells’ ability to respond to insulin can also happen together. Once the prod Continue reading >>
How Does Eating Affect Your Blood Sugar?
Part 1 of 8 What is blood sugar? Blood sugar, also known as blood glucose, comes from the food you eat. Your body creates blood sugar by digesting some food into a sugar that circulates in your bloodstream. Blood sugar is used for energy. The sugar that isn’t needed to fuel your body right away gets stored in cells for later use. Too much sugar in your blood can be harmful. Type 2 diabetes is a disease that is characterized by having higher levels of blood sugar than what is considered within normal limits. Unmanaged diabetes can lead to problems with your heart, kidneys, eyes, and blood vessels. The more you know about how eating affects blood sugar, the better you can protect yourself against diabetes. If you already have diabetes, it’s important to know how eating affects blood sugar. Part 2 of 8 Your body breaks down everything you eat and absorbs the food in its different parts. These parts include: carbohydrates proteins fats vitamins and other nutrients The carbohydrates you consume turn into blood sugar. The more carbohydrates you eat, the higher the levels of sugar you will have released as you digest and absorb your food. Carbohydrates in liquid form consumed by themselves are absorbed more quickly than those in solid food. So having a soda will cause a faster rise in your blood sugar levels than eating a slice of pizza. Fiber is one component of carbohydrates that isn’t converted into sugar. This is because it can’t be digested. Fiber is important for health, though. Protein, fat, water, vitamins, and minerals don’t contain carbohydrates. These components won’t affect your blood sugar levels. If you have diabetes, your carbohydrate intake is the most important part of your diet to consider when it comes to managing your blood sugar levels. Part 3 Continue reading >>
13 Diabetes Myths That Don't Lower Blood Sugar
Skipping meals could potentially push your blood glucose higher. When you don't eat for several hours because of sleep or other reasons, your body fuels itself on glucose released from the liver. For many people with type 2 diabetes (PWDs type 2), the liver doesn't properly sense that the blood has ample glucose already, so it continues to pour out more. Eating something with a little carbohydrate signals the liver to stop sending glucose into the bloodstream and can tamp down high numbers. Skipping meals can also lead to overeating, which can cause an increase in weight. And if you take certain diabetes medications that stimulate the body's own insulin such as common sulfonylureas, or you take insulin with injections or a pump, you risk having your blood glucose drop too low when you skip or delay meals. Going Low-Carb Low-carb diets "are not balanced and deprive the body of needed fiber, vitamins, and minerals," says Constance Brown-Riggs, M.S.Ed, R.D., CDE, CDN, author of The African American Guide to Living Well with Diabetes (Career Press, 2010). Recently, Brown-Riggs counseled a PWD type 2 who ate very little carbohydrate. The result: poor energy and severe headaches. Brown-Riggs helped the person balance out his meal plan by suggesting fruits, grains, and other carb-containing foods. "His headaches subsided, his energy level was restored, and he was happy to learn that he could eat healthy sources of carbohydrate and manage his blood glucose levels successfully," Brown-Riggs says. The keys to success are to manage portions of all foods, spread your food out over your day, and work with your health care team to devise an individualized meal, activity, and medication plan. Eating Pasta Al Dente It is best to eat your spaghetti al dente, says David J. A. Jenkins, M. Continue reading >>
Why Your Fasting Blood Sugar Might Still Be High On Low Carb
It’s not too uncommon to have slightly high fasting blood sugar on low carb and keto diets. Is this a problem? It depends on your insulin levels, as outlined by Dr. Ted Naiman below.

How To Maintain Normal Blood Sugar
If you are one of the millions of people who has prediabetes, diabetes, metabolic syndrome or any other form of “insulin resistance,” maintaining normal blood sugar levels can be challenging. Over the past several decades, these chronic disorders have swept through the U.S. and many other nations, reaching epidemic proportions and causing serious, but often preventable, side effects like nerve damage, fatigue, loss of vision, arterial damage and weight gain. Elevated blood sugar levels maintained for an extended period of time can push someone who is “prediabetic” into having full-blown diabetes (which now affects about one in every three adults in the U.S.). (1) Even for people who aren’t necessarily at a high risk for developing diabetes or heart complications, poorly managed blood sugar can lead to common complications, including fatigue, weight gain and sugar cravings. In extreme cases, elevated blood sugar can even contribute to strokes, amputations, coma and death in people with a history of insulin resistance. Blood sugar is raised by glucose, which is the sugar we get from eating many different types of foods that contain carbohydrates. Although we usually think of normal blood sugar as being strictly reliant upon how many carbohydrates and added sugar someone eats, other factors also play a role. For example, stress can elevate cortisol levels, which interferes with how insulin is used, and the timing of meals can also affect how the body manages blood sugar. (2) What can you do to help avoid dangerous blood sugar swings and lower diabetes symptoms? As you’ll learn, normal blood sugar levels are sustained through a combination of eating a balanced, low-processed diet, getting regular exercise and managing the body’s most important hormones in othe Continue reading >>
Low Carb Vs. High Carb - My Surprising 24-day Diabetes Diet Battle
Twitter summary: What I learned from doubling my carb intake: the same average blood sugar, but four times as much hypoglycemia, more work, stress, & danger. As a teenager, I ate a high carb diet that included lots of Goldfish crackers, white sandwich bread, pasta, and white potatoes. It was tasty, but it put my blood sugars on a wild roller coaster every single day. Things turned around in college when I learned about nutrition, got on CGM, and spent time with health conscious friends. I soon realized that eating less than 30 grams of carbs at one time was a complete gamechanger. I’ve stuck with that approach ever since. But is this lower carb method actually better for my blood sugars, or have I just been fooling myself? To find out, I took on a somewhat terrifying self-tracking experiment: 12 days of my usual, lower-carb diet, which averaged 146 grams of carbs per day (21% of daily calories). My carbs were primarily from nuts, seeds, vegetables, and a bit of fruit. 12 days of a higher-carb, high whole-grain diet, which averaged 313 grams of carbs per day (43% of my daily calories). My sources of carbs were NOT junk food: plain oatmeal, whole wheat bread, quinoa, wild rice, and fruit. Neither of these was unrealistic. My lower-carb diet was nowhere near Atkins level (20 grams per day), and the higher-carb diet was consistent with the “average” 45% carb diet in people with diabetes (according to ADA). Even though this was a one-person (n=1) experiment, I wanted to be as scientific and fair as possible: eating whole, unprocessed foods in both periods; counting and tracking every single gram of carbohydrate (LoseIt! app); wearing CGM 24/7 and downloading the glucose data to document what happened (Dexcom G5 and Clarity); taking insulin before meals (5-15 minutes pr Continue reading >>
Eating Right But Sugar Still High.
I started a diet (Weight Watchers) in January and have lost weight so why is my sugar still so high? I am on 2500mg of metformin daily. It could be that the meals you are eating still contain more carbs than you can handle. Do you check your blood sugar 2 hours after eating? That would show if the meal was low carb enough. How many carbs do you allow per meal? You may need to lower that number. I know others will jump in here to help you out Eating right means different things for different people. For diabetics, it is usually fruit, cereals, whole grain bread and pastas that raise bgs. Also metformin alone will not compensate for a diet too high in carbs. It works in the liver, not the pancreas. Some type 2 diabetics may need insulin to see lower bgs. 115 pounds, Breast Cancer dx'd 6/16, 6 months of chemo and 6 weeks of radiation 2000 metformin ER, 100 mg Januvia,Glimperide, Prolia, Gabapentin, Meloxicam, Probiotic with a Prebiotic, , Lisinopril, B-12, B-6, Tumeric, Magnesium, Calcium, Vit D, and Occuvite mostly vegan diet, low fat and around 125 carbs a day, walk 5-6 miles every other day and 1 hour of yoga and light weights.

How You Can Have High Blood Sugar Without Carbs
How You Can Have High Blood Sugar Without Carbs Can you have high blood sugar without carbs? Well, its important to look at common beliefs about high blood sugar first. High blood sugar is bad. Carbohydrates raise blood sugar. Therefore carbohydrates are bad. The theory is simple, and yet incredibly flawed. The truth is, you can have chronically high blood sugar even while religiously avoiding every starch and sugar in sight. Low-carb forums are littered with posts asking a very relevant question: Why is my blood sugar so high when Im not eating any carbs? The answer is simple, yet often overlooked. The Hormone that Raises Blood Sugar: No Carbohydrates Required If the body were an engine, glucose would be its fuel. Most people think glucose only comes from carbohydrates (sugar and starch), but protein can also be turned into glucose when there arent enough carbs around to do the job. This is called gluconeogenesis, and its performed by one of the major stress hormones cortisol. When you have high cortisol levels (from diet, lifestyle, etc.), the cortisol rapidly breaks down protein into glucose, which can raise blood sugar levels considerably. For some folks, this results in chronically high blood sugareven if they are on a low-carb diet. The trouble is, cortisol isnt just breaking down the protein you eat. Its doing something far more destructive. The body is quite a smart machine, and it has no problem taking detours to get energy if necessary. If your body isnt getting the energy it needs from your diet, it has a back-up source: its own tissue. It sounds kind of cannibalistic, eating your own lean body tissue for energy. I mean, I seriously doubt any one of you would relish cutting off a chunk of your leg for dinner. I know I wouldnt. But every time your body uses c Continue reading >>
Is Your Fasting Blood Glucose Higher On Low Carb Or Keto? Five Things To Know
This past spring, after 18 months of great success on the keto diet, I tested my fasting blood sugar on my home glucose monitor for the first time in many months. The result shocked me. I had purchased the device, which also tests ketones, when I was diagnosed with pre-diabetes in the fall of 2015. As I embarked on low-carb keto eating, I tested my blood regularly. Soon my fasting blood sugar was once again in the healthy range. I was in optimal ketosis day after day. Not only that, I lost 10 lbs (5 kg) and felt fantastic — full of energy with no hunger or cravings. Before long I could predict the meter’s results based on what I was eating or doing. I put the meter away and got on with my happy, healthy keto life. When my doctor ordered some lab tests this spring, I brought the meter out again. While I had no health complaints, excellent blood pressure and stable weight, she wanted to see how my cholesterol, lipids, HbA1c, and fasting glucose were doing on my keto diet — and I was curious, too. To check the accuracy of my meter against the lab results, on the morning of the test I sat in my car outside the clinic at 7:30 am, and pricked my finger. I was expecting to see a lovely fasting blood glucose (FBG) of 4.7 or 4.8 mmol/l (85 mg/dl). It was 5.8! (103 mg/dl). What? I bailed on the tests and drove home — I didn’t want my doctor warning me I was pre-diabetic again when I had no explanation for that higher result. The next morning I tested again: 5.9! (104). Huh??? For the next two weeks I tested every morning. No matter what I did, my FBG would be in 5.7 to 6.0 (102 to 106 mg/dl), the pre-diabetic range again. One morning after a restless sleep it was even 6.2 mmol/l (113 mg/dl). But my ketones were still reading an optimal 1.5-2.5 mmol/l. I was still burnin Continue reading >>
8 Sneaky Things That Raise Your Blood Sugar Levels
Skipping breakfast iStock/Thinkstock Overweight women who didn’t eat breakfast had higher insulin and blood sugar levels after they ate lunch a few hours later than they did on another day when they ate breakfast, a 2013 study found. Another study in the American Journal of Clinical Nutrition found that men who regularly skipped breakfast had a 21 percent higher chance of developing diabetes than those who didn’t. A morning meal—especially one that is rich in protein and healthy fat—seems to stabilize blood sugar levels throughout the day. Your breakfast is not one of the many foods that raise blood sugar. Here are some other things that happen to your body when you skip breakfast. Artificial sweeteners iStock/Thinkstock They have to be better for your blood sugar than, well, sugar, right? An interesting new Israeli study suggests that artificial sweeteners can still take a negative toll and are one of the foods that raise blood sugar. When researchers gave mice artificial sweeteners, they had higher blood sugar levels than mice who drank plain water—or even water with sugar! The researchers were able to bring the animals’ blood sugar levels down by treating them with antibiotics, which indicates that these fake sweeteners may alter gut bacteria, which in turn seems to affect how the body processes glucose. In a follow-up study of 400 people, the research team found that long-term users of artificial sweeteners were more likely to have higher fasting blood sugar levels, reported HealthDay. While study authors are by no means saying that sugary beverages are healthier, these findings do suggest that people who drink artificially sweetened beverages should do so in moderation as part of a healthy diet. Here's what else happens when you cut artificial sweetener Continue reading >>
Is Low-carb Eating Really Better For Blood Sugar?
A review of popular low-carbohydrate diets finds that while restricting carbs can reduce blood sugar in the short run, evidence in support of long-term benefits is lacking. While very low carbohydrate diets (LCD) promise to cut blood sugars, a review of popular LCDs finds that while very low-carb eating can reduce blood sugar in the short run, little evidence exists to show long-term benefits. The study, published online in the Journal of the American Osteopathic Association, reports that while LCDs may be “slightly better than low fat diets for weight and triglycerides management” they are “not superior for the management of blood glucose, blood pressure, or cholesterol levels.” However, researchers note that physicians should be aware that “available evidence for LCDs is limited because of variable definitions, lack of long-term studies, and lack of patient adherence.” Diets considered ranged from very low carb—less than 20 to 60 grams per day—to less restrictive diets that averaged about 130 grams per day. The American Diabetes Association says diets should be tailored to individual needs, but recommends starting at 45-60 grams of carbohydrates per meal. “Patients can likely follow a version of the low carbohydrate diet for longer than the studies suggest, but we don’t know the health effects of a very low carbohydrate ketogenic diet of less than 20 grams of carbs per day,” says Heather Fields, MD, an author of the study and a doctor of integrative medicine at the Mayo Clinic in Phoenix, Arizona. “With so few people adhering to a truly ketogenic diet long term [more than a year], we will likely never be able to study the health effects in a meaningful way.” Dr. Fields finds that if type 2 patients have not had success with a plant-based, who Continue reading >>
Why Your “normal” Blood Sugar Isn’t Normal (part 2)
Hi, I just found this site and would like to participate. I will give my numbers, etc. First, my last A1c was 6.1, the doc said it was Pre-diabetes in January of 2014, OK, I get it that part, but what confuses me is that at home, on my glucometer, all my fastings were “Normal” however, back then, I had not checked after meals, so maybe they were the culprits. Now, I am checking all the time and driving myself crazy. In the morning sometimes fasting is 95 and other times 85, it varies day to day. Usually, after a low carb meal, it drops to the 80’s the first hour and lower the second. On some days, when I am naughty and eat wrong, my b/s sugar is still low, and on other days, I can eat the same thing, and it goes sky high, again, not consistent. Normally, however, since February, my fbs is 90, 1 hour after, 120, 2nd hour, back to 90, but, that changes as well. In February, of 2014, on the 5th, it was horrible. I think I had eaten Lasagne, well, before, my sugars did not change much, but that night, WHAM-O I started at 80 before the meal, I forgot to take it at the one and two hour mark, but did at the 3 hour mark, it was 175, then at four hours, down to 160, then at 5 hours, back to 175. I went to bed, because by that time, it was 2 AM, but when I woke up at 8:00 and took it, it was back to 89!!!! This horrible ordeal has only happened once, but, I have gone up to 178 since, but come down to normal in 2 hours. I don’t know if I was extra stressed that day or what, I am under tons of it, my marriage is not good, my dear dad died 2 years ago and my very best friend died 7 months ago, I live in a strange country, I am from America, but moved to New Zealand last year, and I am soooo unhappy. Anyway, what does confuse me is why the daily differences, even though I may Continue reading >>
5 Biggest Diabetes Management Mistakes
Over seven years and millions of interactions on Diabetes Daily, we have seen many people make the same mistakes. Here are five of the most common ones along with potential solutions. What mistakes are missing from the list? Share your experience in the comments and help spare your peers some difficult days. Mistake #1: Thinking Only Food Impacts Blood Sugars Carbohydrates, and to a lesser extent fat and protein, impact blood sugars. But food is just one of many factors. Stress – whether it is caused by pain, a fight with a loved one, or intense exercise – increases blood sugars. Activity typically lowers blood sugars, but many forms of exercise can also raise your blood sugar, such as strength-training and sprinting. Exercise that is causing negative stress on your body can also raise your blood sugar. Little known fact: if a 20 minute, pain-free walk regularly increases blood sugars and you haven’t eaten recently, call your doctor and ask for a stress test. This can be an early sign of heart disease. Something is causing that stress. Sleep patterns can change your insulin sensitivity throughout the day. Not getting enough sleep can make you more insulin resistant and lead to higher blood sugars. Hormonal changes can cause your blood sugars to rise and fall. These hormones could be from things like increased stress, growth-hormones, menstruation, and menopause. As you learn about why your blood sugars change, it is critical to look at factors beyond food. Mistake #2: Guessing Your Blood Sugars People are horrible at guessing their own blood sugars. The key problem is that the symptoms of high and low blood sugars are not always consistent. Are you sweating and hungry because of a low blood sugar or because it’s 90 degrees out and you skipped breakfast? Are you Continue reading >>
Using Low Carb Diet And Sugar Is Still High, How Do I Get It Lower?

Common Questions About Blood Sugar
How often should I test my blood sugar? This is a very common question, and the answer isn't the same for everyone. In general, you should test as often as you need to get helpful information. There's no point in testing if the information you get doesn't help you manage your diabetes. If you've been told to test at certain times, but you don't know why or what to do with the test results, then testing won't seem very meaningful. Here are some general guidelines for deciding how often to test: If you can only test once a day, then do it before breakfast. Keep a written record so that you can see the pattern of the numbers. If you control your blood sugar by diet and exercise only, this once-a-day test might be enough. If you take medicine (diabetes pills or insulin), you will probably want to know how well that medicine is working. The general rule is to test before meals and keep a record. If you want to know how your meals affect your blood sugar, testing about 2 hours after eating can be helpful. Test whenever you feel your blood sugar is either too high or too low. Testing will give you important information about what you need to do to raise or lower your blood sugar. If you take more than 2 insulin shots a day or use an insulin pump, you should test 4 to 6 times a day. You should test more often if you're having unusually high or low readings, if you're sick, under more stress than usual, or are pregnant. If you change your schedule or travel, you should also test your blood sugar more often than usual. Talk to a member of your health care team about how often to test based on your personal care plan. What should my test numbers be? There isn't one blood sugar target that's right for everyone with diabetes. It's important to work with your health care team to set Continue reading >>
