How Does Hyperglycemia Happen
Insulin is a hormone that lets your body use the sugar in your blood, which comes primarily from carbohydrates in the food that you eat. Hyperglycemia happens when your body has too little insulin to use the sugar in your blood.
People with type 1 diabetes can have episodes of hyperglycemia every day. Although this can be frustrating, it rarely creates a medical emergency. Not taking enough insulin can lead to hyperglycemia .
Other things that can cause hyperglycemia include:
- Having trouble seeing or concentrating
- Experiencing stomach pain, nausea, or vomiting
- Having sweet-smelling or fruity breath
- Cuts or sores that do not heal, infections, and unexplained weight loss may also be signs of long-term hyperglycemia.
If you notice any of these symptoms, you should check your blood sugar. If your blood sugar is very high, you should also test for ketones in either your blood or urine.
What Factors Affect Blood Sugar
You can guess that carbohydrate intake and insulin production are at least partly responsible for your blood sugar levels. But the list is much longer almost every lifestyle choice you make can affect your blood sugar. Heres just a partial list.
- Exercise can affect insulin sensitivity, leading to lower blood sugar for up to 48 hours.
- Alcohol intake increases insulin production, causing low blood sugar.
- Stress hormones like cortisol can raise blood sugar, because your body wants access to energy in order to escape what it perceives as a dangerous situation.
- Medications, especially statins and diuretics, can raise blood sugar. Statins are used to treat cholesterol, and diuretics for high blood pressure.
- Diet is a major player in blood sugar. Eating too many simple carbs at once can cause levels to skyrocket, while protein intake leads to a slower increase in blood sugar.
- Dehydration raises blood sugar, because with less water in your body the glucose concentration will be higher.
Other surprising factors can affect your blood sugar, like a sunburn or gum disease, so if youre dealing with a blood sugar issue and cant figure out whats causing your spikes and dips, talk to a health care professional.

High Blood Sugar: Causes Complications And How To Lower Blood Sugar
Your body breaks down glucose for energy using the insulin produced by the pancreas. This is required for our bodies to function. Illness can have an impact on the way our pancreas functions. Read this to learn how high blood sugar can affect your health.

Your body requires energy to function, and this energy comes from food. Specifically, your body breaks down glucose for energy using the insulin produced by the pancreas.
Type 1 and type 2 diabetes cause impairment to this breakdown of sugar in the body, causing blood glucose levels to become irregular. When glucose is not broken down into energy, it can build up in the bloodstream and then becomes a health problem.
Your pancreas produces insulin, which breaks down glucose. With type 1 diabetes, the cells that produce insulin are mistakenly attacked by your immune system. As a result of this autoimmune condition, blood sugar levels can become dangerously high without intervention.
Type 2 diabetes occurs when your body no longer responds to insulin as well as it should and then also causes glucose to accumulate in the blood.
What Happens During A Blood Glucose Test
A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out.
For some types of glucose blood tests, you will drink a sugary liquid and wait for an hour before your blood sample is taken:
- A glucose challenge test is used to test for gestational diabetes in pregnancy. If your blood glucose level is higher than normal, you may have gestational diabetes. You’ll need an oral glucose tolerance test to get a diagnosis.
- An oral glucose tolerance test is used to diagnose gestational diabetes, and type 2 diabetes and prediabetes in people who aren’t pregnant. A blood sample will be taken before you have a sugary drink and then again, every hour for the next 2 or 3 hours.

Can Hyperglycemia Be Treated
Your doctor may recommend a low-impact exercise program as your first line of defense. If youre already following a fitness plan, they may recommend that you increase your overall level of activity.
Your doctor may also suggest that you reduce glucose-rich food intake. Its important to maintain a balanced diet and stick to healthy food portions. If you arent sure where to begin, your doctor can refer you to a dietician or nutritionist who can help you establish a diet plan.
If these changes dont help lower your high blood sugar, your doctor may prescribe medication. If you have diabetes, your doctor may prescribe oral medications or change the amount or type of insulin youve already been prescribed.
Youre Developing Blisters Dryness Or Other Skin Changes
Small pieces of extra skin, called skin tags, may form in the creases of skin, especially if you have diabetes and youre trying to find ways to manage your weight, notes the ADA. Dark, thick areas of soft skin may form on the back of the neck or hands, armpits, face, or other areas. These can be a sign of insulin resistance, Zanini says. Blisters, infections, dryness, itchiness, discolorations, and abnormalities of the skin can all be warning signs of high blood sugar. Check with your doctor if these skin changes develop.

What Happens If My Blood Glucose Level Becomes Too Low
Sometimes blood glucose levels drop below where they should be, which is called hypoglycemia. For most people with diabetes, the blood glucose level is too low when it is below 70 mg/dL.
Hypoglycemia can be life threatening and needs to be treated right away. Learn more about how to recognize and treat hypoglycemia.
Treating And Managing Hyperglycaemia
If your blood sugar level is slightly high for a short time, emergency treatment wont be necessary. But if it continues to rise you may need to act fast to avoid developing diabetic ketoacidosis .
If your blood sugar level is 15 mmol/l or more, you should check your blood or urine for ketones. If ketones are present, it is likely that you do not have enough insulin in your body. This means you may need to increase your dose or give yourself an extra dose. Talk to your diabetes team about how to do this if you are unsure.
You should also try to drink plenty of sugar-free fluids to prevent dehydration. And if you are feeling unwell, especially if you are vomiting, you should follow any sick day rules you have been given and contact your diabetes healthcare team for advice.

Is There A Relationship Between Mean Blood Glucose And Glycated Hemoglobin
Go to: Abstract Measurement of hemoglobin A1c is considered the gold standard for monitoring chronic glycemia of diabetes patients. Hemoglobin A1c indicates an average of blood glucose levels over the past 3 months. Its close association with the risk for the development of long-term complications is well established. However, HbA1c does not inform patients about blood glucose values on a daily basis therefore, frequent measurements of blood glucose levels are necessary for the day-to-day management of diabetes. Clinicians understand what HbA1c means and how it relates to glucose, but this is not the case with patients. Therefore, the translation of the HbA1c results into something more familiar to patients seemed a necessity. The scope of this article is to review the literature to search for enough scientific evidence to support the idea of a close relationship between HbA1c and mean blood glucose , and to justify the translation of HbA1c into something that reflects the MBG. Most studies confirm a close relationship between HbA1c and MBG, although different studies result in different linear equations. Factors affecting this relationship may limit the usefulness and applicability of a unique mathematical equation to all diabetes populations.

Is Hyperglycaemia Serious
The aim of diabetes treatment is to keep blood sugar levels as near to normal as possible. But if you have diabetes, no matter how careful you are, you’re likely to experience hyperglycaemia at some point.
It’s important to be able to recognise and treat hyperglycaemia, as it can lead to serious health problems if left untreated.
Occasional mild episodes aren’t usually a cause for concern and can be treated quite easily or may return to normal on their own. However, hyperglycaemia can be potentially dangerous if blood sugar levels become very high or stay high for long periods.
Very high blood sugar levels can cause life-threatening complications, such as:
- diabetic ketoacidosis a condition caused by the body needing to break down fat as a source of energy, which can lead to a diabetic coma this tends to affect people with type 1 diabetes
- hyperosmolar hyperglycaemic state severe dehydration caused by the body trying to get rid of excess sugar this tends to affect people with type 2 diabetes
Regularly having high blood sugar levels for long periods of time can result in permanent damage to parts of the body such as the eyes, nerves, kidneys and blood vessels.
If you experience hyperglycaemia regularly, speak to your doctor or diabetes care team. You may need to change your treatment or lifestyle to keep your blood sugar levels within a healthy range.

Fasting Blood Sugar Test
This test can be done in the lab or the healthcare providers office with a simple finger stickor your doctor may prescribe a meter and have you test regularly at home.
A fasting blood sugar level indicates what your blood sugar is when you havent eaten for at least 8 hours. For adults without diabetes, a normal fasting blood sugar is less than 100 mg/dL. A fasting blood sugar level of 100-125 mg/dL indicates prediabetes, and 126 mg/dL or higher indicates diabetes.
What Are The Signs Of High And Low Blood Sugar
The symptoms vary depending on whether you have hyperglycemia or hypoglycemia. Find out how to spot the warning signs and stabilize your glucose.
One of the challenges of managing diabetes is maintaining consistent blood sugar levels. Even with diligence, some situations can cause high blood sugar, or hyperglycemia, while others can bring on low blood sugar, or hypoglycemia.
After all, its not just carbohydrate intake that influences the amount of glucose coursing through your bloodstream when you have type 2 diabetes. Emotional stress and certain medications can increase your blood sugar levels, and a boost in activity can cause it to drop, says Megan ONeill, CDCES, a medical science liaison for diabetes care at Abbott healthcare company in Monterey, California. Sometimes people experience a spike in their blood sugar early in the morning due to the dawn effect, a temporary surge of hormones that occurs as the body prepares to wake, according to the Cleveland Clinic.
For people with diabetes, managing blood glucose levels is especially important, ONeill says. Levels that are too low or high can result in complications that affect your kidneys, heart, and vision, reduce your quality of life, require expensive interventions, or even be fatal.
- Between 80 and 130 milligrams per deciliter before meals
- Less than 180 mg/dL two hours after meals

If your test results show you have prediabetes, ask your doctor or nurse if there is a lifestyle change program offered through the CDC-led National Diabetes Prevention Program in your community. You can also search for an online or in-person program. Having prediabetes puts you at greater risk for developing type 2 diabetes, but participating in the program can lower your risk by as much as 58% .
How Does High Blood Sugar Affect The Body
Monitoring your blood sugar is essential if you have diabetes. Symptoms will get worse if treatment is not provided, and serious health complications can arise as a result. The signs of high blood sugar to look for include fatigue, blurred vision, and headaches along with:
- Frequent urination and thirst: Excess sugar in the blood is passed through the kidneys and into urine. This draws more water into the urine which means more frequent urination. High glucose levels cause thirst even when you are drinking enough fluids.
- Weight loss: Elevated blood sugar levels over time can lead to unexplained weight loss as a result of cells not getting the glucose they need. As a result, they start burning fat instead.
- Numbness: High blood sugar can cause tingling and numbness in the extremities. It is important to note that this is a complication of long-term diabetes and uncontrolled blood sugar levels.

How Can One Tell If I Have Diabetes By Examining My Blood
Your body converts sugar, also called glucose, into energy so your body can function. The sugar comes from the foods you eat and is released from storage from your bodys own tissues.
Insulin is a hormone made by the pancreas. Its job is to move glucose from the bloodstream into the cells of tissues. After you eat, the level of glucose in the blood rises sharply. The pancreas responds by releasing enough insulin to handle the increased level of glucose moving the glucose out of the blood and into cells. This helps return the blood glucose level to its former, lower level.
If a person has diabetes, two situations may cause the blood sugar to increase:
- The pancreas does not make enough insulin.
- The insulin does not work properly.
As a result of either of these situations, the blood sugar level remains high, a condition called hyperglycemia or diabetes mellitus. If left undiagnosed and untreated, the eyes, kidneys, nerves, heart, blood vessels and other organs can be damaged. Measuring your blood glucose levels allows you and your doctor to know if you have, or are at risk for, developing diabetes.
Much less commonly, the opposite can happen too. Too low a level of blood sugar, a condition called hypoglycemia, can be caused by the presence of too much insulin or by other hormone disorders or liver disease.
What Is The Normal Glucose Mmol L Level In A Csf
Normal levels of glucose in the CSF are greater than 50 mg/dL to 80 mg/dL, or 2.8 mmol/L to 4.4 mmol/L. If your levels are lower, you may have an infection. Your healthcare provider will look at your CSF glucose level along with the other CSF tests, and possibly other tests, to better understand what your results mean.

How To Calculate Your Blood Sugar Level: The Complete Guide
To get an accurate reading of your blood sugar level, the best and most effective method is using a glucose meter. This will involve a small prick in your finger so receive a blood sample. The strip is then inserted into the meter and tested.
You may be wondering what your reading should be. There is no normal reading, an ideal reading differs from person to person. Everyone will get different readings at different times of the day. However, there is a rough range to determining a low, normal and high blood sugar level. Blood sugar level is read in mmol/L, which stands for millimoles per liter. Here is a guide as to what an ideal reading is for each diabetic type and non-diabetic patients:
|4 5.9 mmol/L< 7.8 mmol/L||4 5.9 mmol/L< 7.8 mmol/L|
It is advised to check it regularly if you are concerned, show regular symptoms or have diabetes. You should check before meals, exercise, before bedtime and after driving. Everyone is different so it is best to ask your doctor if you are unsure how many times and when you should check your blood sugar levels.
Research shows that over 50% who try to estimate their blood sugar level reading are incorrect. This may be due to over underlying medical conditions that did not know they had or poor lack of judgement. Therefore, this suggests it is very important to test at home to check in on your levels regularly to avoid any unnecessary future complications.
Random Blood Sugar Test
This measures your blood sugar at the time youre tested. You can take this test at any time and dont need to fast first. A blood sugar level of 200 mg/dL or higher indicates you have diabetes.
|140 mg/dL or below||N/A|
*Results for gestational diabetes can differ. Ask your health care provider what your results mean if youre being tested for gestational diabetes.Source: American Diabetes Association
If your doctor thinks you have type 1 diabetes, your blood may also tested for autoantibodies that are often present in type 1 diabetes but not in type 2 diabetes. You may have your urine tested for ketones , which also indicate type 1 diabetes instead of type 2 diabetes.
