Low Blood Sugar Levels Symptoms
Low blood sugar levels or also known as hypoglycemia can happen to anyone but is more common in people with diabetes. Low blood sugar levels can occur if you miss a meal, exercise too hard, or take too much insulin.
Signs and symptoms that your blood sugar might be on the low side include:
- Feeling shaky
- Anxiety or feeling of nervousness
If you have any of these symptoms, it’s important to check your blood sugar levels right away. You can use a home glucose meter to test your blood sugar levels. The ADA recommends that people with diabetes keep a fast-acting source of sugar like glucose tablets with them at all times in case they experience low blood sugar levels.
High Blood Sugar Levels Symptoms
High blood sugar levels or also known as hyperglycemia can occur if you don’t take enough insulin, you miss a meal, or you exercise too little. High blood sugar levels can also be caused by stress, illness, or some medications.
Signs and symptoms that your blood sugar might be on the high side include:
- Increased urination
It’s important to treat high blood sugar levels quickly to avoid more serious problems. You can treat high blood sugar levels by drinking water and taking your diabetes medication or insulin.
It’s important to check your blood sugar levels right away and keep doing that every hour until your sugar levels are back in the normal blood sugar range.
High Blood Sugar: 13 Reasons Your Glucose Levels Are Rising
May 2, 2021
Itâs a fact of life that blood sugar fluctuates throughout the day. These ups and downs depend on a handful of factors, like when you wake up, what you eat, the medications you take, and how you manage stress. So, some variation is normal, to the point that you might not even notice it.
Ignoring blood sugar level changes altogether, though, means youâre ignoring a valuable marker of your health. Especially if you start to have new or unfamiliar symptoms like fatigue, thirst, or brain fog . Learning these symptoms and their causes will give you the tools to better understand your own body, then take the right actions for better long-term metabolic health.

Several Factors May Cause A Persons Postprandial Blood Sugar To Remain Elevated
Smoking after the meal: Studies show that smoking raises blood sugar levels in people with diabetes. Extreme stress: Stress produces the bodys fight-or-flight response triggering the release of stress hormones such as cortisol. These hormones cause the body to release the glucose it has previously stored for energy. Eating or drinking after the meal and before testing the blood sugar: Continuing to eat will keep blood sugars closer to their immediate post-meal levels.
Studies show that 15 to 20 minutes of moderate exercise, such as walking, shortly after a meal may improve glucose metabolism and reduce postprandial glucose levels.
Why Is My Morning Blood Sugar So High
A complex array of factors affects blood sugar levels, including hormones, diet, and lifestyle.
Q: I have prediabetes and now eat minimal carbs and sugar. My doctor told me to monitor my sugar levels, morning and night. At night, two hours after eating, my sugar levels are between 112 and 130 mg/dL . But in the morning, my fasting sugar level is always higher than the night number. Why is that? What am I doing wrong?
There are a few reasons why your blood sugar may be elevated in the morning. First, its important to understand that certain hormonal changes that occur overnight may lead to high blood sugar levels in the morning.

What Is Considered High Blood Sugar
Blood sugar levels are considered high in people with diabetes once theyre more than the recommended 120 mg/dL, however, having a blood sugar of 145 mg/dL usually wont cause any problems .
For most people, high blood sugars become symptomatic once the blood sugar level reaches between 180-200 mg/dL.
Blood sugars above 200 mg/dL need to be treated immediately with insulin , and any blood sugar over 250 mg/dL requires that you do a urine test for ketones, to make sure youre not spiraling into diabetic ketoacidosis .
This is when the bodys blood turns acidic due to prolonged, dangerously high blood sugar levels and ketones in the blood. This can be fatal if not treated immediately.
This can occur when one is sick or battling an infection, due to a pump infusion site failure or even if you forgot to take your insulin for a few days.
Unfortunately, about 25% of newly diagnosed people with type 1 diabetes are diagnosed when they are already in DKA.
If you are experiencing a blood sugar higher than 250 mg/dL along with moderate to high ketones for several hours and cannot get your blood sugar down, contact your doctor immediately and seek emergency medical attention.
People with diabetes are at heightened risk of falling into a diabetic coma from high blood sugar once their blood sugar levels reach 600 mg/dL or higher.
This is a true medical emergency, is extremely dangerous, and can be life-threatening. If you are in this situation, you should call 911.

How Can I Tell If My Blood Sugar Is Irregular
Again, only a doctor can diagnose a problem with your blood sugar. But you may be wondering how to know if it’s something you should get checked out. There can be two main issues with your blood sugar — either it’s consistently too high or too low. Even if you don’t have diabetes, there are some signs that your blood sugar levels are not functioning normally.
Hypoglycemia is a condition in which your blood sugar is too low. Signs include an irregular heartbeat, fatigue, shakiness and tingling or numbness in your face. If you consistently feel this way when you get hungry or between meals, talk to your healthcare provider.
On the flipside, hyperglycemia happens when your blood sugar is too high, and can happen to nondiabetics. Symptoms include frequent urination, increased thirst and headache. If you think you’re hyperglycemic and can’t keep fluids or food down, call for emergency medical assistance.
How Do I Prepare For The Plasma Glucose Level Test And How Are The Results Interpreted
To get an accurate plasma glucose level, you must have fasted for at least 8 hours prior to the test. When you report to the clinic or laboratory, a small sample of blood will be taken from a vein in your arm. According to the practice recommendations of the American Diabetes Association, the results of the blood test are interpreted as follows:
Fasting blood glucose level
- If your blood glucose level is 70 to 99* mg/dL . . .
- What it means: Your glucose level is within the normal range
*Values between 50 and 70 are often seen in healthy people
**The condition of “prediabetes” puts you at risk for developing Type 2 diabetes, high blood pressure, and blood lipid disorders

What Blood Sugar Goals Should I Be Aiming For
The American Diabetes Association recommends that most people with diabetes aim for the following blood sugar goals:
- Preprandial : 80-130 mg/dL
- Postprandial : Less than 180 mg/dL
Your doctor will likely set different goals for you based on many factors including your age, how long you’ve had diabetes, other health problems you have.
How Do I Measure Blood Sugar
If you have diabetes, you probably already keep a watchful eye on your blood sugar through the use of a continuous glucose monitor or a blood sugar meter . Blood sugar measurement is also typically included in routine lab work for people without diabetes — your physician will usually order a glycated hemoglobin test, which measures your average blood sugar over the past two to three months.
Say your A1C test comes back with no sign of diabetes — constantly measuring your blood sugar can still be helpful. For instance, some people experiment with using a CGM to see how their body responds to different types of food. However, it’s good to note that this is a fairly cost-intensive way of figuring out your nutrition, and writing down a food diary that includes how you felt after each meal will also help you figure out what to eat.
Check out these blood sugar monitors if you’re looking for recommendations on how to keep track of your levels at home.

Blood Sugar Chart: Summary
The fasting blood sugar, 2-hour post-meal blood sugar, and HbA1C tests are important ways to diagnose prediabetes and diabetes, as well as indicate how well a persons diabetes is being managed. If you think you have diabetes, its important to not try and diagnose yourself by doing a finger-stick with a home blood glucose meter. There are strict standards and procedures that laboratories use for diagnosing diabetes therefore, you should get tested at your doctors office or at a laboratory.
Its also important to talk with your doctor to make sure you understand a) how often you should have certain tests, such as a fasting blood glucose or HbA1C test b) what your results mean and c) what your blood sugar and HbA1C targets are.
If you have not been previously diagnosed with prediabetes or diabetes but your results are above normal, your doctor may recommend other tests and should discuss a plan of treatment with you. Treatment may include lifestyle changes, such as weight loss, a healthy eating plan, and regular physical activity. You may need to start taking diabetes medications, including insulin. If you are diagnosed with diabetes, its recommended that you learn how to check your blood sugars with a meter so that you and your health care team can determine how your treatment plan is working for you.

Blood Sugar Targets In People With Diabetes
In people with diabetes, blood sugar levels are too high, either because the individual isn’t making any insulin , or isn’t able to make or use insulin efficiently . As a result, glucose levels then remain elevated in the blood and fuel can’t enter cells.
But generally, according to the ADA , for most non-pregnant adults with diabetes the fasting blood sugar target range should be in the range of between 80 and 130 mg/DL. Meanwhile, the ADA suggests the after-meal goal about two hours after eating for the same subset of patients should be less than 180 mg/DL.
Overall, eating plenty of fruit and vegetables, maintaining a healthy weight, and getting regular physical activity alongside medication can all help stabilize and maintain normal blood sugar levels in people with type 2 diabetes.
For pregnant women who have pre-existing diabetes or develop diabetes during pregnancy, ADA guidelines are generally lower. Fasting glucose targets for this population should be less than 95 mg/DL, while they suggest that the after-meal goal about two hours after eating should be below 120 mg/DL.
Recommended Target Blood Glucose Level Ranges
The NICE recommended target blood glucose levels are stated below for adults with type 1 diabetes, type 2 diabetes and children with type 1 diabetes.
In addition, the International Diabetes Federations target ranges for people without diabetes is stated.
The table provides general guidance. An individual target set by your healthcare team is the one you should aim for.
*The non-diabetic figures are provided for information but are not part of NICE guidelines.

What Is The Dawn Phenomenon
Another reason for high nighttime blood sugar levels is the dawn phenomenon. The dawn phenomenon occurs early in the morning when the body naturally signals your liver to produce glucose, giving your body the energy it needs to wake up.
The hormonal changes associated with the dawn phenomenon happen to people with or without diabetes, though those without diabetes do not experience hyperglycemia. If you take insulin, you may need to try a new basal insulin or adjust the timing and amount of your basal dose or your nighttime basal rates to cover an early morning rise.
What Is A Normal Blood Sugar Level
According to the American Diabetes Association, a normal fasting blood sugar is less than 100 mg/dL.
A fasting blood sugar reading of 100-125 mg/dL indicates prediabetes, and a reading above 125 indicates diabetes.
|Fasting Blood Sugar|
|100 mg/dl to 125 mg/dl||Prediabetes|
|126 mg/dl or higher||Diabetes|
If you test your blood sugar two hours after eating or drinking something containing sugar instead , the numbers to look for are:
|Oral Glucose Tolerance Test|
|140 mg/dl to 199 mg/dl||Prediabetes|

How Do You Manage Blood Sugar
It’s not easy to manage your blood sugar, but it’s important to do so if you have diabetes. There are many things you can do to keep your blood sugar levels in the healthy range.
The first step is to understand what causes your blood sugar levels to go up and down. This will help you make choices that keep your blood sugar levels within your target range.
Why Your Blood Sugar Level May Be High
Based on the ADA guidelines above, if your blood sugar is above 180 mg/dL two hours after a meal, it is considered above the normal range. What might cause your glucose or blood sugar to rise? Consider the following factors:
- Consuming more carbohydrates or a larger meal than usual
- Not taking enough insulin or oral diabetes medication based on carbohydrates or activity levels
- Reduced physical activity
- Side effects from medications like steroids or antipsychotics

What Causes Hypoglycemia In A Child
Hypoglycemia can be a condition by itself. Or it can be a complication of diabetes or other disorder. Its most often a problem in someone with diabetes. It occurs when theres too much insulin. This is also called an insulin reaction.
Causes in children with diabetes may include:
Too much insulin or oral diabetes medicine
The wrong kind of insulin
Incorrect blood-glucose readings
Tingling feelings around the mouth
Nightmares and confusion on awakening
The symptoms of hypoglycemia can be like other health conditions. Make sure your child sees his or her healthcare provider for a diagnosis.
Beyond Normal Goals: Whats An Optimal Glucose Level And Why Does It Matter
Exact numbers for what is considered optimal glucose levels to strive for while using CGM to achieve your best health are not definitively established this is a question that is individual-specific and should be discussed with your healthcare provider. With that said, research shows that there is an increased risk of health problems as fasting glucose increases, even if it stays within the normal range, making finding your optimal glucose levels all the more important.
While the International Diabetes Federation and other research studies have shown that a post-meal glucose spike should be less than 140 mg/dL in a nondiabetic individual, this does not determine what value for a post-meal glucose elevation is truly optimal for your health. All that number tells us is that in nondiabetics doing an oral glucose tolerance test, researchers found that these individuals rarely get above a glucose value of 140 mg/dL after meals.
So, while this number may represent a proposed upper limit of whats normal, it may not indicate what will serve you best from a health perspective. Many people may likely do better at lower post-meal glucose levels. Similarly, while the ADA states that a fasting glucose less than 100 mg/dL is normal, it does not indicate what value is optimal for health.
Repeated high glucose spikes after meals contribute to inflammation, blood vessel damage, increased risk of diabetes, and weight gain.
