Symptoms Of High And Low Blood Sugar
Managing your blood sugar levels is essential for your energy, brain function, mood and basic functions of your body. Our nutritionists explain the symptoms of high and low blood sugar, what normal levels of blood sugar should be, and how to lower or increase your blood sugar healthily through your diet.
Is Having High Blood Glucose Dangerous
In short, it can be. Zanini says that untreated high blood glucose can lead to a wide range of health issuesâsome of the most common being chronic inflammation, heart disease, vision impairment, kidney disease, nerve damage, tooth decay, damaged blood vessels, and periodontal disease.
Having high blood glucose also puts us at risk of mitochondrial dysfunction and oxidative stress. The former is a condition in which mitochondria fail to produce energy for cells. The latter occurs when free radicals outnumber antioxidants in the body and increase the risk of disease and other damage.
Phipps notes to avoid these risks, catching high blood glucose early on, then taking action to treat it is extremely important.
You Notice Tingling And Numbness In Your Hands Or Feet
As mentioned, uncontrolled blood sugar can cause nerve damage, also known as diabetic neuropathy. What you may notice is a tingling sensation or even numbness in your hands and feet. Some people experience pain in their hands and feet as well. Though neuropathy is most common in people who have had diabetes for a long time, it can occur in anyone with poorly controlled diabetes.

Low Blood Glucose: Hypoglycemia
Hypoglycemia can occur when blood glucose drops below normal levels or drops too quickly. Your blood glucose level is too low if it is under 70 mg/dL.
Hypoglycemia can be caused by:
- A combination of these factors

Signs Your Blood Sugar Is Too High
Did you know that too high blood sugar can lead to serious health problems? If you suffer from diabetes, then your blood sugar levels might be too high.
If you’re worried that yours is and don’t know where to start, this blog post will delve into some of the early signs and symptoms of high blood sugar and offer tips on lowering your blood sugar if needed.
Signs That Your Blood Sugar Is Not Stable
Besides feeling hangry, Shapiro says there are other signs that your blood sugar is low, often as a result of spiking it too high previously. “If you eat a large load of sugar or carbs solo , you may feel energized for a bit but in an hour or so you might find yourself sweating, tired, shaky, confused. These are signs of low blood sugar, a quick drop in energy that leaves your body weak,” explains Shapiro.
People may joke about “hanger,” but the feeling is very real, according to Shapiro. When your blood sugar is low, “You may also find you feel agitated, and hungry, which makes you feel angry or grumpy too.”
At the end of the day, you shouldn’t feel extremes in either direction. If you’re eating balanced meals, you should feel good most of the time and when you get hungry, it should happen slowly rather than being a dramatic feeling all at once, according to Shapiro.
Healthy sources of protein like fish and healthy fats like nuts and avocados can help keep your blood sugar balanced.

Being Extra Thirsty And Having To Urinate More Than Usual
This is a common but not-so-obvious sign of blood sugar that is too high: feeling really thirsty and needing to drink more than usual. Excessive urination, known as polyuria, occurs when glucose builds up in your blood, and your kidneys begin working harder to get rid of the extra glucose, says Zanini. If your kidneys cant keep up and adjust blood sugar so that it returns to a normal level, the excess sugar is flushed out of your body through urine, she adds. You may become dehydrated and get dizzy.
How Is Dka Treated
DKA is very serious, but it can be treated if you go to the doctor or hospital right away. To feel better, a person with DKA needs to get insulin and fluids through a tube that goes into a vein in the body .
Let your parents or someone on your diabetes health care team know if you have any of these symptoms or are sick and don’t know what to do to take care of your diabetes.
Always wear a medical identification bracelet or necklace that says you have diabetes. Then, if you are not feeling well, whoever’s helping you will know to call for medical help. Medical identification can also include your doctor’s phone number or a parent’s phone number.

Complications Of High Blood Sugar
Diabetes is one of the main causes of high blood sugar levels, but there are other causes that can impact your blood glucose and your risk for hyperglycemia.
Hyperglycemia is the medical term for high blood sugar levels. You can have temporary spikes in blood sugar after eating a large meal or as a result of medication side effects. Chronically elevated blood sugar levels are dangerous and common in those with diabetes. Without treatment, you run the risk of a diabetic coma.
Ketoacidosis is a condition that develops when elevated blood glucose levels go untreated. Without glucose to use for fuel, your body begins to burn fat instead and produces ketones. When there are too many ketones in the blood, it will turn acidic, which can very quickly lead to ketoacidosis, a diabetic coma, and even death.
People without diabetes can develop a similar condition known as ketosis, but they can tolerate a certain level of ketones because inulin is still effectively working.
Diabetic hyperosmolar syndrome is another serious complication of high blood sugar. This is more common among individuals with type 2 diabetes and is triggered by an infection or illness.
As a result of the high blood sugar, your body tries to push out the excess glucose by passing it through your urine. Without treatment, this can result in life-threatening dehydration so prompt medical attention would be necessary.
Things That Cause High Blood Sugar
High blood sugar can be caused by a variety of factors. The most common factors that contribute to high blood sugar include:
- Overeating/eating large portion sizes
- Using old, expired insulin
- Injecting insulin incorrectly
Most patients with high blood pressure dont have a known cause. This is called essential hypertension or primary hypertension, Dr. Raja adds.

What Are The Signs & Symptoms Of Dka
The symptoms of diabetic ketoacidosis usually don’t develop all at once they usually come on slowly over several hours. People who have DKA may:
- feel really tired
- feel really thirsty or pee way more than usual
- have a dry mouth and signs of dehydration
These symptoms are caused by the high blood sugar levels that usually happen before someone develops DKA. If the person doesn’t get treatment, these signs of DKA can happen:
- abdominal pain
- unconsciousness
How To Check Blood Sugar At Home
If you aren’t sure whether your blood sugar is high or in the normal range, one thing you can do is test your sugar. This is especially helpful if you’re concerned about diabetes or prediabetes, but anyone can benefit from monitoring their sugar.
“There are easy ways to do this, and that will show you what your blood sugar responds to and how much of certain foods you can eat without disrupting your blood sugar. It is a great self-research experiment,” says Shapiro. Some types of blood glucose monitors require a prescription, but many are OTC and anyone can purchase one.
If you’re not quite ready for a monitor, you can still check in with yourself and take notes throughout the day of how certain foods and activities make you feel. “Otherwise you can monitor how you feel, your energy, how often you get hungry,” says Shapiro. “These are great measures of blood sugar levels.”

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 eliminate glucose-rich foods from your diet. 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.
How Do Carbs Affect Blood Sugar
Carbs in food make your blood sugar levels go higher after you eat them than when you eat proteins or fats. You can still eat carbs if you have diabetes. The amount you can have and stay in your target blood sugar range depends on your age, weight, activity level, and other factors. Counting carbs in foods and drinks is an important tool for managing blood sugar levels. Make sure to talk to your health care team about the best carb goals for you.

Build A Clear Picture Of How Your Blood Sugar Works By Using A Cgm
As weve seen, everyones blood sugar control works differently, so it can be helpful to know whether morning spikes are a problem for you.
Unless you have diabetes, it is unlikely that you check your glucose regularly.
Checking your glucose a few times throughout the day or continuously via CGM can help to show how your body is handling changes in glucose levels during fasting or after meals.
When To Contact Your Doctor
Hyperglycemia can turn into a medical emergency like DKA and HHS that requires immediate intervention by your doctor or a local emergency department. If you have two blood sugar readings of 300 mg/dL or more, or have blood sugar above your target range for more than a week, seek immediate medical help.
Signs of hyperglycemia include:
- Stomach pain, nausea, or vomiting
- Shortness of breath

How Do I Treat Hyperglycemia
You can often lower your blood sugar level by exercising. However, if your blood sugar is above 240 mg/dl, check your urine for ketones. If you have ketones, do not exercise.
Exercising when ketones are present may make your blood sugar level go even higher. You’ll need to work with your doctor to find the safest way for you to lower your blood sugar level.
Cutting down on the amount of food you eat might also help. Work with your dietitian to make changes in your meal plan. If exercise and changes in your diet don’t work, your doctor may change the amount of your medication or insulin or possibly the timing of when you take it.
How Do I Prevent Hyperglycemia
- Exercise to help lower blood sugar. Work with your healthcare provider to make a daily activity plan.
- Follow your meal plan if you have one. Learn how carbohydrates impact your blood sugar, and work with your diabetes care team to find the best meal plan for you.
- Maintain a healthy weight.
- Dont smoke.
- Limit drinking alcohol. Alcohol can raise blood sugar levels, but can also cause dangerously low blood sugar levels. Work with your provider to determine how much is safe to drink.

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.
7 minute read
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.

If My A1c Is Normal My Glucose Is Good
An A1C result thatâs below 5.7% is normal âs standards, but having a result below that number isnât the end of the story. Pregnancy, hemoglobin variants, anemia, liver disease, and certain medications can cause inaccurate A1C results.
Additionally, the A1C test is measuring your average glucose value over the past 3 months, but averages inherently do not capture highs and lows. So, you could have a normal average while also having abnormal glucose spikes. The A1C test should only supplement your regular blood sugar testing, not replace it completely.
