The blood sugar concentration or blood glucose level is the amount of glucose (sugar) present in the blood of a human or an animal.
The body naturally tightly regulates blood glucose levels (with the help of insulin that is secreted by pancreas) as a part of metabolic homeostasis.
If blood sugar levels are either increased or decreased by a greater margin than expected this might indicate a medical condition. Dramatic changes of blood sugar levels have significant physical symptoms and will increase your risk of diabetes-related complications. Download your blood sugar levels log and keep track of your own blood sugar levels – write down all of your measured values. Please note that you should perform several consecutive blood glucose tests and not rely on one single measurement. The next chart displays all possible blood sugar (glucose) levels along with a short explanation of what the indicators are.
Chronically high blood sugar (diabetes) is caused by a number of abnormalities in the body, one of them being the affected vascular walls of small and large arteries (diabetic micro-and macro-angiopathy) in a process called atherosclerosis.
High blood sugar levels affect the arteries throughout the body, especially the organs which have the richest blood circulation: heart, brain, kidney, senses, nerves and other organs. If the high blood sugar is associated with disturbances in lipid metabolism (blood fat), the abnormalities are more intense.
Typical symptoms of high blood sugar levels (diabetes) are thirst, frequent urination and unexpected weight loss. Type 1 diabetes symptoms are severe and last for a short time before the disease is diagnosed.
There are basically two main tests which are conducted to determine whether someone has diabetes. When being tested for diabetes by a impaired fasting glycemia test, blood sugar levels will normally be taken after around eight hours of fasting. An impaired glucose tolerance test involves taking a concentrated amount of glucose and then measuring blood sugar levels after two hours. Medical alcohol to clean the skin where you will prick your finger, a sterile tool to prick your finger, some test strips and a glucose meter to read the test strip. The fact is that with Diabetes type 1 body’s cells that produce insulin are destroyed. With type 2 diabetes your body does not use insulin properly (also known as insulin resistance). Refer to this article for more information on how brown fat tissue may help control your disease or even revert it! A patient with diabetes is at a 5 times greater risk of developing cardiovascular disease than patient without diabetes. Disturbances in the metabolism of blood sugar levels are mainly the consequence of heredity (diabetes in the family), age (over 40), poor diet, excessive body weight (obesity) and physical inactivity. People with high blood sugar levels can lower their blood sugar levels by maintaining normal body weight, eating healthy and by physical activity.

MY BLOOD SUGAR WAS 129 THIS MORNING SOME TIMES IN THE 30S ONCE IN A WHILE BELOW 100 THE REST OF THE DAY SEEMS TO BE OK MY 90 DAY AVE. Is it possible to get any graphical method of say weekly or some times 10 days irregular days with NORMAL graphical line.Soas to check and be precautionary by diabetic patient itself.
This is inspite of the fact that she is not given any medicine after lunch and no food after 10p.m.
Can anybody tell from where insulin comes after midnight and from where sugar comes after 5 a.m.?
A fasting reading this morning I did was 83 then I ate and checked again after and hour or so it was 110. My normal blood sugar reading is between 102 to 110 before breakfast my goal is to keep it from going any higher 126 in the morning before breakfast is high to me .I am type 2 diabetic. Nigel Smith, look at what you are eating in the morning and try something with a bit more fibre. Being new to this, and someone who does not do things by halves, I have been tracking my glucose levels some 4 or 5 times a day. SORY ABOUT SPELING I NEVE COOD.i was told by doctors 9 muths ago I had tipy 2 and givin metermothin 500mg 4 times a day ime falling asleep in the afternoon as ime finding it hard to keep awake can eney one help. What you can do is to change your diet and delay the possible development of this disease by following some simple diet rules. The BS numbers recommended by the popular institutions or organizations for healthy, pre-diabetes and diabetes are generally slightly in a high side.
However, many health professionals think their patients are intelligent, smarter, and brave enough. If your blood-glucose levels are more than the above-said range, then you are at increased risk towards diabetes. You are not only risked towards diabetes; additionally, even undiagnosed as diabetes for years, your body develops diabetes complications, read on to know why. The spectrum of neuropathy is in diabetes and impaired glucose tolerance Neurology January 14, 2003 vol.

How is it that people who are doing what they are “supposed” to be doing –- eating healthy, exercising, maintaining a normal body composition -– still have blood sugar issues? The second source of fuel for the mitochondria -– glucose –- has an equally important role in the function of cells.
With the epidemic of diabetes and metabolic syndrome plaguing the industrial world in recent years, blood sugar and insulin have gotten their fair share of media attention. In fact, blood sugar balance is a major tenet of virtually every diet book from The Zone to The Atkins Diet.
These are health-conscious, educated individuals who do not spend their time eating Twinkies, bingeing at McDonalds and competing in the World’s Laziest Couch Potato competition.
Rather, we see people who eat well, exercise regularly, have normal body composition and take supplements, but still don’t feel well.
Insulin resistance, which is characterized by two things: chronically elevated blood sugar levels, and subsequent elevated insulin levels to help deal with the blood sugar. And while each of these have their separate issues metabolically, both will cause issues with the function of mitochondria because there is not a steady stream of blood sugar available for ATP (energy) production. When someone is insulin resistant, glucose cannot effectively enter into the cell –- chronically elevated insulin levels create dysfunctional insulin receptor sites on the cell.
Because blood sugar is not adequately entering the cells, it stays in general circulation rather than being stored. Characteristic symptoms of insulin resistance include: fatigue after meals, craving for sweets that doesn’t go away when sweets are eaten, increased thirst, and frequent urination.
Individuals with this pattern and periods of low blood sugar will have surges of insulin, rather than chronically elevated levels. Normally, the body should respond to low blood sugar by producing cortisol to increase blood sugar levels. Symptoms are usually relieved after eating because meals provide a source of glucose that their body could not create itself. Because their bodies rely on adrenaline to elevate blood sugar, people with some degree of hypoglycemia can have insulin surges between meals, rather than following meals, or chronically, as in insulin resistance. But here is one of the biggest points: looking healthy, having a muscular body, and exercising regularly does not mean that you have normal blood sugar management.
Though there are a number of mechanisms involved in this cycle, here is a basic explanation. In other words, you could have a perfect diet and exercise program, but if you have elevated cortisol levels, you may also be increasing your blood sugar from the inside.
Two hours after a meal, it will ideally be between 85 and 100 depending on the size and quality of the meal.
You could eat a meal, and then track your blood sugar at 30 minute intervals for 2 hours following a meal.
A good protein-based meal with adequate levels of healthy fat and fibre should not raise your blood sugar levels too high.


For most of you, the first step toward eating properly for blood sugar management is starting with the Precision Nutrition System.   Indeed, over 85% of our clients see the types of results they’re looking for by following this program. However, for the other 15% that use the program and still need to go a bit deeper, working with a coach through Precision Nutrition Coaching is the next step. Blood sugar dysregulation and elevated insulin levels have negative impacts on numerous physiological systems in the body. But on a fundamental level if adequate glucose cannot enter a cell, the mitochondria will not be able to produce optimal amounts of ATP to run the cells, organs and systems of the body, and we will not be optimally healthy, much less have the body we desire.
The mitochondria use two primary sources of fuel to produce the energy required to run your body effectively: oxygen and glucose.
These are basic fundamentals to health and fitness that must be addressed before deciding which supplement works better or whose workout program is the best for fat loss.
In it you’ll learn the best eating, exercise, and lifestyle strategies — unique and personal — for you.
When food intake stops, the body is compelled to live of the energy it has stored, primarily body fat. Because body fat is the main energy source during a fast, this time period can be very effective in reducing body weight that is carried in the form of excess fat tissue. Within the first twenty four to forty eight hours of fasting, the body enters into a state known as ketosis. All of our body’s muscles and organs, aside from the brain, can use fat directly as energy.
Once blood sugar starts to drop, as it inevitably does during a fast as the glycogen (sugar) stores gradually become depleted, then Ketones become the only other alternate source of fuel for the brain.
Ketosis is a completely natural state and an essential bodily function, especially during a fast. Within forty eight hours of commencing my fast, I became very mentally alert and sleeping beyond four to five hours per night was impossible. At the time I did not have access to Ketone testing, so instead I tracked my blood sugar level up to ten times per day. Late evening on day four I was so wide awake, which worried me a bit, even though I was feeling fine. What may be regarded too low a level, is only relevant, if the liver cannot make ketones to replace the blood sugar as an energy source.
The transformation in my physique was not extraordinary, but quite impressive after only four days. My photos and weight measurements are all taken late morning in a fully hydrated state versus first thing in the morning where the body can be somewhat dehydrated. The photo on the 16th of January 2015 was taken approximately twelve hours after I decided to end my initial four day fast. I ate food normally for three days and resumed fasting on the 19th of January 2015 while continuing to monitor my blood sugar several times a day.
In an attempt to deplete my glycogen (sugar) stores quickly and thereby enter into a state of higher fat burning faster, I performed a brief hill sprint workout for the first five days during my second round of fasting.
Having done extensive testing (since my fasting experiment) on my blood sugar and ketone levels immediately before and after exercise, I now have some doubts whether this attempt was successful in speeding up my body’s fat burning, it may even have been a hindrance. The immediate effect of intense exercise (at least on my body), is an elevation of blood sugar which is the opposite of what is needed when trying to burn body fat for fuel. I also found, that my blood sugar level would stay elevated for several hours after my workout.
The high recordings on days 1 to 5 ended up being the ones immediately after my sprint workout. An interesting observation, was that I ran faster times for each sprint on day 5 compared to day 1.
To me, this demonstrated how the body always preserves and maintains enough glycogen stores in order to physically perform at a high level when needed – despite being deprived of food intake for several days. However, as mentioned earlier, the danger was only relative if my liver had not produced ketones from body fat stores to replace blood sugar as my major energy source.
I also maintained a light exercise regime throughout the entire fasting period, consisting of a 40 minute mountain hike twice a day, as well as my 15 minute daily handstand routine.
On the morning of day 10, I ascended the mountain hike in my fastest time ever and proceeded to make a personal best, for the amount of time I could hold a hand stand.
Had I been breaking down muscle tissue, it would have been almost impossible to perform physically on day 5 (faster sprint times) and day 10 (PB hand stand and hike time) as I did. Below are the final before and after comparison photos of my entire fasting period spanning a total of sixteen days, including three days of non fasting.
I view fasting, when done properly, as a way of re-compositioning the body and achieving one’s ideal body fat percentage without losing lean muscle, in the process. Fasting may even be the quickest, safest and most efficient way to shed body fat – because of the natural high fat burning rate, while the body is in a state of ketosis.
Here you see my latest weigh in and photo session on the 12th of April 2015, compared to the 28th of January – the last day of fasting. A monitoring meter like the Precision Xtra will tell you instantly what your blood ketone level is.
The blue strips shown here are used to test your blood sugar, while the purple are for ketone testing.
These are the terms which Dr Jeff Volek and Dr Stephen Phinney, in their book The Art and Science of Low Carbohydrate Performance attribute to the ascending ketone blood level. Diabetic Keto Acidosis is a condition which can only occur in people with type one diabetes. In the Optimal Ketone Zone, Dr Volek and Dr Phinney estimate that Ketones are being utilized most effectively as energy by the brain, but also to fuel muscles and other organs. During Starvation Ketosis, fat is being metabolized and converted into Ketones at a higher rate. At 4.37pm on the 28th of January, the last day of fasting, I finally got access to Ketone testing.
In The Daily Ketone Advantage, I have written about the benefits of being in ketosis on a daily basis. According to the results from my self testing, drinking coffee seems to very consistently, correlate with a rise in ketone level. While fasting, I only drank water plus two to three cups of coffee with heavy cream a day, so in a sense I was getting a very small amount of calories daily. Every time I tested the effects of coffee, it seemed to stimulate ketone production – or at the very least, I can say, it never seemed to inhibit my ketones from rising. Here are a few snap shots of my daily blood sugar and blood ketone range at 7, 14, 21 and 28 days after completing my fasting experiment.
Seen here is a detailed description of my testing on the 25th of February – 4 weeks after ending my fast.
By 4.34pm I took my third test for the day, after having had a second cup of coffee with heavy cream and otherwise remaining sedentary by sitting down most of the afternoon doing computer work.
I find, without a doubt, that remaining sedentary in combination with having coffee will give me the lowest blood sugar level and highest measure of ketones. 6.22pm was approximately 20 minutes after completing my regular  40 minute mountain hike followed by a brief hill sprint session. 11.03pm, just before going to bed and about 2 hours after having eaten dinner, my blood sugar had returned to normal and ketones were once again rising. At the time of writing this post, my daily low level of ketones, seems to be on the rise once again. This essentially means, that I am maintaining Starvation Ketosis in a fully fed state and therefore very effectively metabolizing the high amount of fat I consume on a daily basis into energy.
I have found exercise and more so intense physical activity, to be a major factor which lowers ketones and raises blood sugar.
Currently, I am experimenting with how to maintain a high state of ketosis while simultaneously increasing my exercise volume and intensity.
I hope you have found this post informative, interesting and maybe helpful if you have ever been curious about or experimented with ketosis, fasting and a high fat low carbohydrate diet yourself. Feel free to leave a comment below or ask me any question regarding my experiment and I will do my best to answer it for you.
After exercise, I was always fine and as I found out, my blood sugar always jumped up after especially intense exercise.


An interesting observation I’ve made on several occasions, is that black coffee will also produce a rapid rise in my Ketone levels and often wonder whether this is a coincidence or another specific effect from maybe the caffeine?
Blood sugar level (or blood sugar concentration) is the amount of glucose (a source of energy) present in your blood at any given time. Diabetes is among the risk factors for major non-communicable diseases: cardiovascular (coronary) disease, cerebral vascular disease and peripheral vascular diseases. Over the time a patient’s condition worsens as body cannot make enough insulin to keep blood glucose at normal levels. Disturbances in the metabolism of blood sugar were present in 20% of adult Europeans during 2002-2005 a study showed. This way you might prevent or delay disease and enhance your health and physical performance. Definitely cut out the sweets, and especially the sodas but really you need to be controlling carb intake because carbs are sugar.
I have been taking my readings every morning since I have been released (about 2 weeks) my Blood has been back in forth from 60 to 89 but this morning I didn’t wake up til 11:30 am and it was 138! He is 4 ft tall and weighs 48lbs so as you can tell he is not over weight in fact his height and weight are perfectly proportionate to each other. Given the fact that your mother has type 2 diabetes you are under greater risk to develop diabetes type 2 as well (although this relation has never been confirmed by scientists).
I know it recommends that you eat fruit, but my mother’s blood sugar only got under control after she stopped eating fruit?
Postprandial blood glucose levels should be higher not lower than random blood sugar levels. Healthy glucose level is the BS number generally noted among the young non-diabetic people. These institutions do so base on an older study, which predicted those who have diagnosed as pre-diabetes has progressed to diabetes early due to mental strain.
Are anemia and low oxygen delivery to blame?) I focused on oxygen, one of the two fuel sources for what is arguably one of the most important components of your cell, the mitochondria. And with good reason: imbalanced blood sugar levels are at the crux of many health issues, including being overweight. As a result, the body must produce higher levels of insulin to remove glucose from the blood stream, which causes even greater metabolic dysfunction. People with hypoglycemia can experience symptoms such as lightheadedness, irritability, shakiness and fatigue between meals, which is often relieved after eating.
However, in this case, periodically hypoglycemic people usually have low adrenal function and rely on adrenaline to elevate blood sugar between meals, which causes the shakiness and and lightheadedness between meals. In fact, researchers have started using new terms like “non-obese insulin resistance” and “atypical metabolic syndrome” because normal-looking people are having blood sugar management issues. A good blood chemistry screen will contain enough markers to adequately identify patterns of blood sugar mismanagement.
They usually cost around $50 and give you the ability to look at your blood sugar throughout the day. If it does, either the macronutrient ratio was off, the meal was too large, or in some cases, you might have a sensitivity to the food that causes a stress response and elevates blood sugar. Clinically, these are “high priority” situations because if either one of these processes are not working correctly, nothing will.
The objective of a fast is to give the body a break from digesting food, though allowing the natural repair processes within the body, to take place. This is a natural condition where compounds called ketones start to produce in the liver, from body fat being mobilized for energy. The main purpose of this test was to lose some body fat and experiment with being in high-level Ketosis for a prolonged period of time. Knowing that Ketones must go up whenever blood sugar goes down, made this an indirect way of measuring my state of Ketosis. Without doing a proper before and after body composition test, there is really no way to know for certain, but judging from my photos and how I felt throughout, I don’t believe this was the case. This happens in a scenario like fasting or if eating a high fat and very low carbohydrate diet on a consistent basis.
I then went for an easy 30 min walk followed by a cup of coffee with heavy cream and remained quite sedentary for the next few hours, sitting in front of my computer.
As you can see, this meal did not affect blood sugar and only helped to increase my ketone level. Did you experience any hypoglycaemic episodes during very low blood sugars and also after exercise?
I’m testing and tracking how my workout performance is in a fasted state, so far the results are encouraging. This blood sugar levels chart is not 100% accurate due to different thresholds set in different countries around the world. I do take insulin (long acting) once in the morning and Glucophage 750 mg once in the evening as per doctor\’s advice. Do not use it though, unless you are monitoring your blood sugar levels and are already familiar with what those levels are.
My doc suggested I might be hypoglycemic because of some of the particular symptoms I’ve had.
Sometimes with exercise, glucagon is produced by your liver if your blood sugar is too low and this will increase the test result. As per your website, it states that fasting levels till 180 for his age group are fine whereas other websites like Wikipedia and Mayo clinic state that 100-125 is pre-diabetic. Any way the doctor just called me and told me that his blood glucose levels are high but his insulin levels are normal.
I have an appointment for a HBA1C test, my doctor said it’s just routine (I am not diabetic). The results suggest IGT may cause or contribute to small-fiber neuropathy, which is similar in phenotype to the painful-sensory neuropathy commonly encountered in diabetes. Without oxygen, it is impossible for your cells to work at their full capacity or for you to be healthy. Excess sugar or carbohydrates, excessively large meals or glycemically imbalanced meals can excessively elevate blood sugar levels, causing this cycle to begin. For example, if you eat celery and almond butter, or a salad with grilled chicken, your blood sugar should not go above 120 at any point after the meal.
If we did not have this storage capability, we could not sleep through the night between dinner and breakfast, without having to wake up and snack every few hours. I have had symptoms of hypoglycemia in the past (dizziness, increased heart rate, fatigue), but overall, I’m a very healthy individual. Regrettably I have found that diabetes nurses have just told me that diabetes is a function of previous smoking ( I never have) and I am over weight ( I’m not) so I am lacking confidence in their ability to view me as an individual and advise accordingly. Would you please explain why is there so much of a difference and which one should I actually believe in?
My family has a strong history of diabetes and I had gestational diabetes with her brother and sister, but not when I was pregnant with her.
The only information she gave me was to change his diet and get the levels checked again in three months. Small nerve fibers are prominently affected and may be the earliest detectable sign of neuropathy in glucose dysmetabolism. Two-hour OGTT is more sensitive than other measures of glucose handling in screening these patients? You might need to check your blood glucose before meals and get insulin coverage for meals. The reliance of doctors on two-hour glucose-tolerance test results allows people to live for years with blood sugars high enough to promote complications long before they are diagnosed even pre-diabetes. I must also add that my father is a diabetic (which explains why i have a blood glucose tester) and diabetes runs in my family.
