High Blood Sugar Symptoms
Hyperglycemia is the medical term for high blood sugar. Hyperglycemia happens when the body doesnt have enough insulin or when it cant use insulin correctly. Many things can cause high blood glucose levels like Type 1 diabetes, Type 2 diabetes, stress, illness, or the dawn phenomenon. If you have hyperglycemia or suspect you may have it, talking with a healthcare provider is always a good idea. A doctor can help you determine whats causing your high blood sugar levels and lower it to a healthy range.
Here are some of the most common symptoms that may indicate hyperglycemia:
- Vision loss
You should seek immediate medical attention if your blood sugar reaches 400 mg/dL or higher.
When patients experience any of these accompanied by elevated blood sugar levels, diabetic patients are advised to go directly to the ER to avoid diabetes-induced coma, says Vikram Tarugu, MD, a gastroenterologist and the CEO of Detox of South Florida. Patients who have elevated blood sugar may also present with frothy, ketone-like smelling breath.
Here are some lifestyle changes and medical treatments that can help treat hyperglycemia:
Normal And Diabetic Blood Sugar Ranges
For the majority of healthy individuals, normal blood sugar levels are as follows:
- Between 4.0 to 5.4 mmol/L when fasting
- Up to 7.8 mmol/L 2 hours after eating
For people with diabetes, blood sugar level targets are as follows:
- Before meals : 4 to 7 mmol/L for people with type 1 or type 2 diabetes
- After meals : under 9 mmol/L for people with type 1 diabetes and under 8.5mmol/L for people with type 2 diabetes
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.

Sometimes you may have symptoms of fatigue, excessive urination or thirst, or unplanned weight loss. However, often people have no symptoms of high blood glucose and find a diabetes diagnosis surprising.
Are Low Blood Sugar Levels Dangerous
Yes, low blood sugar symptoms can cause problems such as hunger, nervousness, perspiration, dizziness and even confusion if untreated, low blood sugar may result in unconsciousness, seizures, coma, or death. Low blood sugar levels begin at 70 mg/dL or less. People with diabetes who take too much medication or take their usual amount but then eat less or exercise more than usual can develop hypoglycemia. Although much rarer, hypoglycemia may develop in some people without diabetes when they take someone elses medication, have excessive alcohol consumption, develop severe hepatitis, or develop a rare tumor of the pancreas . The treatment for hypoglycemia is oral glucose intake (15. 0 grams of sugar, for example, 1 tablespoon of sugar, honey, corn syrup, or IV fluids containing glucose. Recheck your blood sugar levels in about 15 minutes after treatment is advised.

Recommended Blood Glucose Targets For People With Diabetes
|AIC*||Fasting blood glucose/ blood glucose before meals||Blood glucose two hours after start of meal|
|Target for most patients with diabetes||7.0%|
|If A1C targets not being met**||4.0 to 5.5||5.0 to 8.0|
*An A1C is an average of your blood glucose levels over the past three months. Learn more about the A1C here.
**Must be balanced against the risk of hypoglycemia
What Does A1c Stand For
Hemoglobin A1C , commonly called A1C, stands for glycosylated hemoglobin. An A1C test provides information on how well-controlled a persons diabetes is. It does this by measuring the percentage of red blood cell hemoglobin protein that has sugar stuck to it and provides a three-month average of your blood glucose levels, explains , MD, a board-certified endocrinologist at the Center for Endocrinology at Mercy Medical in Baltimore. The higher blood sugar levels are, the more glucose attaches to hemoglobin. The results provide patients and their healthcare providers with information on how well their treatment, diet, and medication is working and whether adjustments are necessary.
There are a few reasons a doctor might suggest an A1C test:
- To make a diagnosis of Type 2 diabetes
- To test for prediabetes
- To monitor blood sugar levels
- To determine if treatment adjustments are needed
The A1C blood test is not for diagnosing Type 1 diabetes, gestational diabetes, or cystic fibrosis-related diabetes, according to the National Institute of Diabetes and Digestive and Kidney Diseases .

How To Save On The Freestyle Libre With Singlecare
If you dont have it yourself, you probably know at least one person living with diabetes. More than 30 million people in the U.S. alone have the condition. Which means youre likely familiar with the hassle of having to monitor glucose levels at all times. The process involves pricking your finger tip with a needle to test a drop of bloodouch!
When you have diabetes, its crucial to make sure its under control by testing your glucose levels often, based on your doctors recommendation. Luckily, for those who are sensitive to it or just tired of the repetition, there is an easier way: the Freestyle Libre, an FDA-approved glucose monitoring system that works as an alternative to the finger stick.
Controlling Blood Glucose Levels
Uncontrolled blood sugar can result in regular episodes of hyperglycemia . This can cause a variety of symptoms including:
- Dry mouth
These symptoms are uncomfortable to experience but there are things you can do at home to reduce your blood sugar. In terms of drinks, water is the best as it will help to maintain hydration and dilute excess sugar in the blood. Also, try to add more fiber to your diet to reduce your blood sugar apples, bananas, oranges, and strawberries are all fibrous fruits.
However, uncontrolled blood sugar levels can also lead to more severe, long term disease. Poorly managed diabetes leads to vision loss, kidney problems, nerve damage, heart attack, and stroke. Therefore, if your blood sugar level reaches 16.7mmol/L, this could be dangerous and you need to seek immediate medical attention.

How Does Freestyle Libre Work
The Freestyle Libre comes with a 14-day sensor that is worn on the upper arm. It lets you monitor your blood sugar levels anywhere and at any time. The sensor captures the glucose concentrationin the interstitial fluid every minute and records the glucose concentration every 15 minutes. All this data is stored in an eight-hour log. The set also comes with a user manual, a USB cable, and a power adapter.

Hba1c Test For Diabetes Diagnosis
An HbA1c test does not directly measure the level of blood glucose, however, the result of the test is influenced by how high or low your blood glucose levels have tended to be over a period of 2 to 3 months.
Indications of diabetes or prediabetes are given under the following conditions:
- Normal: Below 42 mmol/mol
- Prediabetes: 42 to 47 mmol/mol
- Diabetes: 48 mmol/mol
There are two types of blood sugar levels that may be measured. The first is the blood glucose level we get from doing finger prick blood glucose tests. These give us a reading of how high our levels are at that very point in time.
The second is the HbA1c reading, which gives a good idea of our average control over a period of 2 to 3 months. The target blood glucose levels vary a little bit depending on your type of diabetes and between adults and children.
Where possible, try to achieve levels of between 4 and 7 mmol/L before meals and under 8.5 mmol/L after meals. The target level for HbA1c is under 48 mmol/mol .
Research has shown that high blood glucose levels over time can lead to organ and circulation damage.
Keeping blood glucose above 4 mmol/l for people on insulin or certain medications for type 2 diabetes is important to prevent hypos occurring, which can be dangerous.
Your doctor may give you different targets. Children, older people and those at particular risk of hypoglycemia may be given wider targets.

What Is High Blood Sugar
If your blood sugar levels are chronically higher than normal, then this is referred to as hyperglycaemia. This is a common issue for those suffering from diabetes. The condition can also affect pregnant women who have gestational diabetes and occasionally those who are severely ill .
Some of the symptoms of hyperglycaemia include:
- Increased thirst
- Blurred vision
- Issues with concentration and/or thinking
If severe hyperglycaemia is left untreated the condition can lead to organ and tissue damage as the excess glucose present in the body can make it difficult for the organs and cells to function correctly. The disorder can also impair the immune system response in the healing of wounds and cuts.

What Should I Do After I Check My Blood Glucose
Write the blood glucose number in a log book or on a log sheet , and:
- Include all of your blood glucose numbers.
- Write a comment if there is a reason the blood glucose is above or below target.
- Take your blood glucose meter with you when you are away from home.
- Know your blood glucose numbers when you call the clinic or the doctor.
- Bring your blood glucose meter and blood glucose records to all your appointments.
- Bring a list of any questions that you may have.
Take Things One Day At A Time
While you can understand how diabetes works on an intellectual level, the reality is that things can sometimes happen that feel out of your control. This can be a very stressful and scary time for the child but also for the parent, McCrudden says. The needles can be painful or anxiety-inducing at first. Or, maybe your child is embarrassed about dealing with the condition in front of other kids or feels like a burden.
Diabetes management is a balancing act, says Lisa Goldsmith, of Natick, Massachusetts, whose daughter was diagnosed at 7. You can do everything right and still get high or low blood sugars. It is not an exact science and you will not ever have perfection. But you will figure out a routine and develop a new normal. The more you all adjust to the condition, the more good days you will have.

What Is Considered A Normal Blood Sugar Level
The normal blood sugar level for a healthy, non-diabetic adult is determined by when and how blood sugar levels are tested.
The below information describes what normal blood sugar levels are prior to and after meals and what the recommended HbA1c and Haemoglobin A1c levels are for those with and without diabetes.
If you are diabetic, it is advisable to consult with your doctor in order for appropriate blood sugar level targets to be set based on your age, the severity of your condition, medications taken and overall health status.
Now That Youre Checking Your Blood Glucose What Do The Numbers Mean
Depending on your diabetes treatment plan, your doctor or diabetes educator may advise you to check once a week, once a day or up to 10 times a day . But what does it mean when you see a 67, 101 or 350 on your meter? And what is a normal blood sugar, anyway? Great questions! After all, if you dont know what the numbers on your meter mean, its hard to know how youre doing.
The American Diabetes Association provides guidelines for blood glucose goals for people with diabetes, and the goals vary depending on when youre checking your glucose:
Fasting and before meals: 80130 mg/dl
Postprandial : Less than 180 mg/dl
By the way, these guidelines are for non-pregnant adults with type 1 or type 2 diabetes. Children, adolescents and pregnant women may have different goals.
Your blood glucose goals may be different, however. If youre younger, have had diabetes for a shorter amount of time or are not taking any medicine for your diabetes, your glucose goals might be a little tighter, or lower. Likewise, your blood glucose goals may be higher than what ADA recommends if youre older, have diabetes complications, or dont get symptoms when your blood glucose is low.
Bottom line: talk with your health-care provider about the following:

Target Blood Sugar Ranges For Pregnant People With Diabetes
Blood sugar targets during pregnancy are lower due to hormonal influences. The ADA, AACE, and Joslin Diabetes Center have slightly different guidelines for target blood sugar levels during pregnancy. In general, pregnant women with diabetes will want to follow individual guidelines provided by their endocrinologist.
The ADA recommends maintaining blood sugar levels of 95-140 mg/dL for pregnant women. However, some providers recommend an even tighter goal of blood glucose levels below 89 mg/dL before a meal and below 120 mg/dL after a meal.
To keep close tabs on levels, most diabetes specialists recommend that women with diabetes during pregnancy check their blood sugar:
- First thing in the morning
- Before all meals
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.
