When this normal process goes wrong, there is either not enough insulin to do the signalling or the cells are "insulin resistant", that is, they do not seem to understand what the insulin is trying to tell them to do about the glucose.
My name is Dr Iris Bell, and I am an alternative medicine doctor, researcher, and educator educated at Harvard and trained at Stanford Medical School, as well the University of California - San Francisco. For normal people, their system keeps blood sugar in the range of 70-100 milligrams per deciliter while fasting (after not eating overnight, for instance).
Different age groups may have somewhat different cut-offs that define what is "too high." If the blood sugar stays high for long periods of hours, someone can develop damage to their body's tissues, especially kidneys, blood vessels in the brain and heart and nerve damage in peripheral nerves that normally detect pain, vibration, and temperature in the toes and fingers. Once a person has been diagnosed with diabetes, they usually need to use a combination of diet, exercise, weight loss, and medications to control blood sugar levels. The drugs are not always effective or are only partly effective in lowering blood sugar (and sometimes they overshoot and cause serious short term problems of very low blood sugar levels that can cause seizures, brain damage, or even death), and they can cause their own serious side effects, and so reducing the risk of diabetes is always preferable to taking drugs to treat it once it develops. Diabetics who do not maintain their blood sugar levels are at risk of experiencing the symptoms of high blood sugar levels.
Most blood sugar spikes usually occur after a person has consumed a meal that contains sugar.
If you or someone you know is at risk for contracting diabetes or is already has diabetes, that person should know the symptoms associated with high blood sugar in order to preemptively deal with the symptoms. The excess blood glucose in the bloodstream that the body cannot convert into energy is then processed using the urinary tract.
The brain will respond to excess sugar within the bloodstream by telling the body to drink more water. Increased amounts of glucose within the blood stream can lead to eye diseases such as diabetic retinopathy. High glucose levels within the body can lead to damaged blood vessels due to a hardening of the arteries. Most people with Type 2 diabetes have heard about some of the serious complications that can result from years of high blood sugar levels. Once you know your acceptable range, keep close track of your normal glucose sugar level by testing after meals two to four times a day.
A chart that just keeps track of your levels will go far in helping you monitor your control. Whenever your blood sugar levels are outside their range or different from the usual, refer to your supplemental diary. An A1C (sometimes refered to as Hemoglobin A1c) test measures the amount of glucose that sticks to your red blood cells. Your blood sugar chart and your A1C test will give your doctor a complete picture of how your blood sugar management is going.
Once repeated A1C tests show that your blood sugar levels are acceptable and stable, you won’t have to go for A1C tests as often. A chart can be your best and most useful tool in the fight against the ravages of diabetes.
High blood glucose (called hyperglycemia by medical professionals) is the defining characteristic of all types of diabetes.
Signs and symptoms of high blood glucose are often what lead people with undiagnosed diabetes to visit their doctors and, consequently, get diagnosed. The dehydrating effect of polyuria is a key player in many of the other signs and symptoms of high blood glucose, including polydipsia.
The relationship between excessive urination and excessive thirst is often misinterpreted by people experiencing high blood glucose, especially before diabetes is diagnosed. Complicating matters, many people reach for a soda when they’re thirsty, and most sodas contain both some form of sugar and caffeine. If cells aren’t able to gain access to glucose, they send out hunger signals via a variety of signaling hormones, including leptin, ghrelin, orexin, and PYY 3-36. First, the loss of fluids from excessive urination can lead to a low level of body fluids, which can make you weigh less. Second, if insulin levels are too low for glucose metabolism, your body will switch to burning fat to maintain cellular metabolism, and burning fat can lead to weight loss (just what you’re trying to do at the gym, right?). Teenage girls with Type 1 diabetes have been known to manipulate this biological phenomenon via an eating disorder called diabulimia. Urinary tract infections (UTIs) and yeast infections can occur in both men and women, but they are much more common among women, and they’re particularly common among women with diabetes. UTIs, on the other hand, are quite a bit more complicated, and high blood glucose contributes to them in several ways beyond providing glucose-rich urine for the bacteria to grow in. In addition, elevated glucose reduces blood circulation, which in turn reduces the ability of infection-fighting leukocytes (white blood cells) to get where they are needed in a timely manner in sufficient numbers to fight off infections. High blood glucose greatly slows the healing of skin and soft-tissue infections because neutrophils, the most common type of leukocyte in the immune system’s arsenal, are particularly vulnerable to high levels of glucose.
Another critical element of wound healing is a sufficient supply of oxygen, and the delivery of oxygen can be reduced by either peripheral neuropathy (nerve damage) or peripheral vascular disease (blood vessel disease) – both common conditions caused by or made worse by high blood glucose. A less dangerous but highly vexing and common side effect of high blood glucose is dry, itchy skin. Last but not least, nerve damage can interfere with the normal operation of sweat glands, affecting one of skin’s natural moisturizers and leading to dry skin.
Speaking of dryness, blurry vision from acute high blood glucose is also a result of the dehydrating effect of excessive urination.
Chronic high blood glucose, on the other hand, can lead to retinopathy, or damage to the back of the eye that can affect vision and ultimately even lead to blindness. Acute hyperglycemia can cause headaches and difficulty concentrating in a fashion similar to polyphagia – in which starving cells send out hunger signals because they can’t access the glucose circulating in the blood. When your blood glucose is high, your body is neither storing nor utilizing glucose properly. In fact, nearly all the signs and symptoms of high blood glucose can contribute to making you feel fatigued, even exhausted. Both constipation and diarrhea can be caused by high blood glucose, acting on different sections of the bowel. The two intestines have very different jobs, which helps to explain how high blood glucose can affect them differently. When neuropathy from elevated blood glucose affects the enteric nerves – the gut’s command and control system – in the small intestine, the result can be dysfunctions in motility, leading to delayed emptying into the large intestine. Constipation can also be caused or made worse by the dehydrating effects of excessive urination and by some medicines, especially narcotic pain killers, some antidepressants, and the calcium channel blocker class of high blood pressure medicines. Erectile dysfunction, or difficulty maintaining an erection, is a common side effect of high blood glucose, and roughly half of men with diabetes over the age of 50 experience it. A healthy erection requires healthy nerves, healthy blood flow, the right balance of hormones, and sexual stimulation.
High blood glucose can adversely affect erections in three ways: hormonal, vascular, and neurologic. Making matters worse, there are a number of common medicines that can contribute to or worsen erectile dysfunction. High blood pressure can also contribute to erectile dysfunction, as can a build-up of low-density lipoprotein (LDL) cholesterol in the corpora cavernosa supply arteries.
The good news is that the drugs Viagra (sildenafil), Cialis (tadalafil), and Levitra (vardenafil) can all help counteract the loss of nitric oxide, helping the blood vessels dilate, and increasing blood flow to the penis.
But when you consider all the other biological manifestations of high blood glucose – the three polys, infections, slow healing of injuries, itchy skin, blurred vision, headaches, fatigue, and gastro-intestinal distress – is it any wonder we might be irritable? While the causes that lie behind the symptoms of high blood glucose are fascinating, the real value of symptoms is in the message they carry: Blood glucose is too high. But you have it in your power to make the symptoms go away, and to keep them from coming back, by keeping your blood glucose in control.

Diabetes blood sugar levels chart: what is a normal blood, Keep in mind that the blood glucose level before a meal for a non diabetic person and a person with prediabetes may be very similar. Hyperglycemia – wikipedia, the free encyclopedia, Hyperglycemia, or high blood sugar (also spelled hyperglycaemia or hyperglyc?mia, not to be confused with the opposite disorder, hypoglycemia) is a condition in. Diagnosis of diabetes and prediabetes – national diabetes, Diagnosis of diabetes and prediabetes. Hypertension (high blood pressure) health center – webmd, One of the most dangerous aspects of hypertension is that you may not know that you have it.
In order to have optimal health you will want to eat foods that maintain a stable blood sugar. When you reduce your carbohydrate intake enough you will inevitably have to increase your fat consumption. Not only is Fat consumption and ketosis good for fat loss, it is also excellent for mental performance.
For many athletes they have been told that carbohydrates are absolutely necessary for athletic performance. There is an emerging field of research that shows the potential for ketosis preventing and possibly curing cancer (1).


There is no doubt that there are many benefits to living in a state of ketosis and I have personally enjoyed them with my own experience. The field of research on ketosis will continue to develop over the years and I think it has excellent health benefits and possibilities. I know the daily challenges of diabetes first-hand, and I know where to look to find drug-free answers for you in working to reverse your diabetes or prevent pre-diabetes from becoming a diagnosed case of type 2 diabetes, and reduce your risk of complications. Blood sugar can go up and down depending on diet, specific points in time (it may be highest in the mornings when the body naturally releases the most cortisol, an essential hormone that is also released under stress but that is in the system all the time in some amount), after exercise, and during infections. Lifestyle changes, if done thoroughly and properly, can work just as well as any drug and have a much safer long term outcome in terms of side effect risks. After the body has finished processing the body, the sugar levels then return back to equilibrium.
It is much better for a person to be cautious and visit the doctor because they feel that they are experiencing symptoms rather than wait until the symptoms take their toll. Light signals your brain that it's time to wake up and starts preparing your body for ACTION. But according to new research, your nightly slumber may have more to do with Type 2 diabetes and insulin resistance than you think.
The autonomic nervous system is composed of nerves that regulate your heart function and breathing. The more thoroughly and precisely you use your blood sugar log, the better you’ll be able to manage your diabetes. Then in the notes section of your blood sugar chart, write down any unusual activity that might have affected the strange levels.
This glucose count gives physicians a good idea of your average blood sugar levels during the life of the red blood cells.
Your careful notation of your lifestyle habits in your blood sugar log will help the doctor recommend certain non-invasive lifestyle changes. Stable diabetics may only have to have their levels tested once or twice per year to make sure that they are still on track. But only if you use it correctly to thoroughly record and investigate the nature of your blood sugar levels. How does high blood glucose cause frequent urination, make your vision go blurry, or cause all of those other things to happen? 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. But each sign or symptom has a biological underpinning, or a specific cause behind the effect.
Acute hyperglycemia lasts only briefly and is often the result of a high-carbohydrate meal, a missed dose of medicine, stress, or illness. But signs and symptoms of high blood glucose can also occur after diabetes is diagnosed and treatment has been started. Polyuria is the result of a runaway biological and chemical chain reaction that feeds on itself. Normally, the kidneys serve as filters, removing waste products and returning cleansed fluid back to the body.
The cells are pumping water into the bloodstream, and the kidneys, unable to reabsorb this fluid during filtering, are uncontrollably flushing water from the body. In rare cases, polyuria can top out at 20—25 liters per day, about half the body’s total fluid volume. Many people assume that excessive urination is caused by the excessive thirst, and not the other way around.
The sugar raises the blood glucose level even higher, and the caffeine, a diuretic, makes the polyuria worse. Excessive hunger isn’t really caused so much by a high blood glucose level as by a low insulin level. All of these hormones signal the brain’s hypothalamus to trigger the sensation of hunger.
That glucose is full of calories, so when there are high levels of glucose in your urine, you’re literally peeing calories away as your body tries to jettison the excess glucose.
They keep their weight low by keeping their blood glucose high, allowing them to eat more food while maintaining a lower body weight. In fact, women with diabetes are two to three times more likely to have bacteria in their urine than women who don’t have diabetes. Long-term elevated blood glucose can lead to a number of complications, including neuropathy, or damage to nerve tissue, which can affect a wide variety of body systems. High blood glucose also reduces phagocytosis, the process leukocytes use to ingest bacteria.
In fact, skin problems on the feet and lower legs are a sign of atherosclerosis – hardening and narrowing of the arteries and its attendant reduction in circulation – a disease all too common in people with diabetes. Unique to people with diabetes, diabetic dermopathy shows up as scaly circular or oval patches of discolored skin that resemble age spots. As you will recall, when the concentration of glucose in the blood is high, the body attempts to dilute the blood by pulling fluid from cells into the bloodstream. Recent research has shown that by the time of diagnosis, 35% of people with Type 2 diabetes already have some degree of retinopathy. If you don’t believe it, consider that while the brain represents about 2% of your body weight, it devours fully 25% of the glucose you consume. You’re not burning energy efficiently, nor are your cells getting the fuel they need when they need it.
Exhausted people often resort to eating high-carbohydrate snacks for a boost of quick energy, and this, of course, raises the blood glucose level more, making the problem worse rather than better. When high blood glucose affects the small intestine, the result is often diarrhea; when it affects the large intestine, the result is often constipation.
The job of the small intestine is to absorb nutrients from digested food, and the job of the large intestine is to absorb water from indigestible waste material. This causes the stagnation of fluids in the small intestine, allowing bacterial overgrowth that causes bloating, abdominal pain, and diarrhea. Slow-moving waste is essentially dehydrated – or dried out too much – by the large intestine, resulting in constipation.
To form an erection, nerve signals cause the blood vessels that supply the corpora cavernosa to dilate, so that blood flow to the chambers increases. On the hormonal front, high blood glucose interferes with the body’s production of nitric oxide, a so-called vasodilator that triggers the hormonal chain reaction that relaxes the blood vessels and allows the corpora cavernosa to fill with blood. Many high blood pressure pills, especially those in the families of beta blockers and diuretics, and some antidepressants, can interfere with vasodilation (or the widening of blood vessels).
The mood-altering effects of high blood glucose are well known to the loved ones of persons with diabetes and well documented by research.
Simple carbohydrates are the worst and generate massive spikes in blood sugar and subsequent insulin. When blood sugar is stable your body is getting all it needs for various functions and fueling the brain.
Despite popular media and conventional wisdom, in almost every study low carbohydrate diets dominate. Your body will switch from using sugar as a primary fuel source to using fat as a primary fuel source.
The theory is that cancer relies on glucose as its energy source; remove the energy source and the cancer dies. If you are considering trying a ketogenic diet you should figure out what your objectives are and what you want to achieve.

A study out of Sydney University found that staying up into the wee hours of the night significantly increases your risk of developing Type 2 diabetes. Like other nerves in the body, the autonomic system can be damaged in a person with Type 2 diabetes when blood sugar levels are high for long periods. Use these tips to make sure your making your blood sugar monitoring work optimally for you. After an examination and blood test, your doctor will give you a more narrow range that you can manage. When used correctly, it will inform you about how your daily activities affect your blood sugar levels from hour to hour. Since blood cells have a lifespan of roughly 3 to 4 months, newly diagnosed diabetics should have an A1C test once every three months. These changes in conjunction with continued monitoring will help you better manage your blood sugar and prevent the diabetes related diseases that often result from unstable levels.
This reduction in testing is one of the best signs that your chart is working optimally to prolong your life and increase its quality.


Commit to your blood sugar chart and your health and you’ll live a longer, healthier life.
Here are some answers to explain what’s going on in your body when you have high blood glucose. Some of the symptoms have a rapid onset, while others require a long period of high blood glucose to set in. It starts in the blood, where high glucose concentrations osmotically pull intracellular fluid into the bloodstream. The return of the cleansed fluid – or reabsorption of fluid – takes place in the renal tubules, the internal structure of the million or so filtering nephrons in each kidney. Thirst signals in the brain are triggered by osmoreceptors, specialized cells in the hypothalamus that detect the level of plasma osmolality – the level of dehydration of the blood – and create the urge to drink fluids when a person is dehydrated. The low insulin level can be either an absolute shortage of insulin, as in Type 1 diabetes, or it can be a relative shortage of insulin, as in Type 2 diabetes. If your high blood glucose level is a new development, you previously maintained a stable weight, and you make no change in your eating habits, you’ll lose weight as a consequence of high blood glucose.
The cause may simply be a case of supply and demand: More glucose gives yeast more opportunities.
Neuropathy can affect the bladder’s ability to contract properly, causing incomplete emptying.
The first is excessive urination, which can actually dehydrate you to the point that your skin tissues begin drying out.
This is because in most cases, people with Type 2 diabetes have elevated blood glucose levels for an extended period before their diabetes is diagnosed.
Examples include occipital neuropathy, or damage to the optic nerve from elevated glucose levels, and a variety of diabetic mononeuropathies, which can affect specific cranial nerves, peripheral nerves, or nerve roots – all of which can lead to headaches of varying intensities. For an erection to occur, a number of complicated hydraulic events has to happen that cause the penis to fill with blood, and then keep the blood trapped inside the penis for a time. As the spongy tissue engorges with blood, it collides with an outer sheath of elastic tissue that encases the chambers. On the vascular front, high blood glucose can be incredibly damaging to blood vessels, potentially reducing the ability of the supply arteries to dilate. Since both high blood pressure and depression frequently accompany diabetes, it’s common for men with diabetes to be on one or more of these medicines. Their method of action is on the hormonal and vascular side of the equation, while the cause of erectile dysfunction among men with diabetes is more often traced to nerve damage, which doesn’t respond to these medicines. But the biological nuts and bolts behind the emotional response aren’t well understood.
High blood glucose does more than trigger biological and chemical processes that make you feel crummy; over time, high blood glucose causes permanent damage to the body.
Consult appropriate health-care professionals before taking action based on this information. A raised level of blood sugar is actually quite damaging and generates systemic inflammation. Ketosis is actually preferable for endurance athletes as it prolongs energy by utilizing both glycogen and body fat stores.
Many people will find it very easy to adhere to the ketogenic diet and achieve very good results.
People whose fasting and 2-hour post-meal blood sugar levels are above those general cut-offs are considered either pre diabetic (if the value is high but not quite past the threshold level to diagnose diabetes) or diabetic. Write this range in your log so you’ll always know where your blood sugar should lie.
Test at the same time each day whenever possible and record the results in your blood sugar chart immediately so you don’t forget. It is often the result of undiagnosed diabetes or of an inadequate diabetes treatment regimen. This is the body’s attempt to equalize the concentration of glucose in the blood with the concentration in the cells. In either case, the amount of insulin in the blood is insufficient to move glucose molecules from the bloodstream into the cells, where they can be used as fuel for cellular processes.
This ultimately leads to hunger pangs that, perversely, make high blood glucose worse when a person responds by eating.
This leaves behind residual pools of static urine in the bladder – the perfect growth culture for bacteria. Tissue necrosis can then extend from the soft tissue into the bone, which is what often leads to amputation: More than 66,000 amputations were performed on persons with diabetes last year. Diabetic dermopathy is not considered dangerous, and there is no treatment for it, but it serves as a visual sign of high blood glucose. When the lens of the eye gets dried out, it becomes temporarily warped, and the eye loses its ability to focus properly. This is also why the American Diabetes Association recommends that people with Type 2 diabetes have an initial dilated and comprehensive eye exam shortly after diagnosis. This can cause problems with thinking, reasoning, and remembering, difficulty staying focused on tasks, and headaches.
If you are also suffering from a lack of proper sleep due to excessive urination during the night, you will feel even more tired. Enteric neuropathy, in addition to laying the ground work for bacterial overgrowth, can in itself be a painful chronic condition similar to the foot pain suffered by people with peripheral neuropathy.
This temporarily chokes off the veins that drain the blood back out of the penis, allowing the erection to stabilize. In a similar fashion, nerve damage from high blood glucose can affect both sensation and nerve signaling involved in the erection process. Also well documented is the fact that high blood glucose causes depression and negatively affects rapid thinking and decision-making skills.
Your body converts dietary and body fat into ketone bodies, which are actually the preferred fuel source for many organs and muscles in your body (1) including the brain. A wide variety of evidence suggests that the ketogenic diet could have beneficial disease-modifying effects in epilepsy and also in a broad range of neurological disorders characterized by death of neurons. Cancer is now being considered to be a disease of metabolic dysfunction rather than previously viewed as a genetic abnormality. You likely know some of the items on the list by heart: thirst, frequent urination, blurry vision, slow healing of cuts, and more.
Chronic hyperglycemia is arguably the more dangerous of the two, as long-term elevated blood glucose has a toxic effect on the body’s tissues.
By diluting the blood with intracellular fluid, the body brings the glucose concentration of the blood closer to normal. Until the glucose levels are normalized, the renal tubules can’t regain the ability to absorb fluids. Fat theoretically has a glycemic index of zero and will have almost no effect on blood sugar.
If you have restricted your carbohydrate intake or have exercised rigorously these storages sites will have capacity. In the state of ketosis many people find their energy levels will remain stable and that fat very easily melts off your body.
Blood flow to the brain also increases during ketosis and has been shown to increase by 39%.
Weight lifters and sprinters will still require carbohydrates to replace glycogen stores after intense workouts. In fact, some of the signs of high blood glucose are actually the aftermath of cellular damage caused by high blood glucose.
Use the tools available to you, such as your blood glucose meter, to see whether your numbers are in target range most of the time. Eating a diet of predominantly protein and fat, with some complex carbohydrates (like vegetables) will help maintain a stable blood sugar. However, if they are full your body has no choice but to convert the excess blood sugar into body fat.
But will still have comparable performance simply using the glycogen stores within the body. You may do just as well by having a low-moderate carbohydrate intake in the form of complex carbohydrates which have a low glycemic index. Sugar can be viewed as rocket fuel for quick spontaneous power and fat as a wood burning stove for long consistent energy. It is something you can experiment with to see how you feel and perform and get a better sense of what it is like. Imagine the storage sites are your gas tank in your car, you can only fill it up so much and if you keep pumping when the tank’s full, gasoline will overflow and spill everywhere.
