How Long After Eating Does Blood Sugar Return To Normal
The blood sugar level falls back to a normal level around 1-2 hours after taking food. During this time digestion slows down and the sugar is absorbed by the tissue.
In diabetics, there can be a sudden spike in blood sugar after eating causing headache, dizziness and discomfort. This is called a post-prandial reaction. Normally, taking prescribed insulin medication can help mediate this problem.
Why Check Blood Sugar Levels
If you take certain medication, like insulin or sulphonylureas, checking your blood sugars is a vital part of living with diabetes. It can help you work out when you need to take more medication, when you need to eat something or for when you want to get up and move around more.
Routine checks can help you know when you might be starting to go too low or too high . Its a way of getting to know your body and how it works. It can help you and your healthcare team spot patterns too. Do you write your results down? You might find that helpful.
But importantly, it will help you stay healthy and prevent serious diabetes complications now and in the future. By complications, we mean serious problems in places like your feet and your eyes. This happens because too much sugar in the blood damages your blood vessels, making it harder for blood to flow around your body. This can lead to very serious problems like sight loss and needing an amputation.
The higher your blood sugar levels are and the longer theyre high for, the more at risk you are.

What Are Blood Sugar Levels
Your blood sugar levels, also known as blood glucose levels, are a measurement that show how much glucose you have in your blood. Glucose is a sugar that you get from food and drink. Your blood sugar levels go up and down throughout the day and for people living with diabetes these changes are larger and happen more often than in people who don’t have diabetes.
You can check your sugar levels yourself by doing a finger-prick test, by using a flash glucose monitor or with a continuous glucose monitor . You can do this a number of times a day helping you keep an eye on your levels as you go about your life and help you work out what to eat and how much medication to take. Find out your ideal target range.
But not everyone with diabetes needs to check their levels like this. Youll need to if you take certain diabetes medication. Always talk to your healthcare team if youre not sure whether thats you theyll give you advice on whether to check them yourself and how often.
And theres also something called an HbA1c, which measures your average blood sugar level from the previous few months. Everyone with diabetes is entitled to this check.
High blood sugar levels increase your risk of developing serious complications. However you manage your diabetes, stay in the know about your blood sugar levels.
Why Is My Blood Sugar Level High

The clinical term for high blood sugar is hyperglycemia. The most common cause of high blood sugar is Diabetes Mellitus or DM. It is a condition where the body cannot absorb glucose due to any abnormality in the production or action of a hormone called Insulin. Diabetes is mainly of two types: Type 1 and Type 2. Majority of diabetics are suffering from type 2 diabetes, caused by reduced action of Insulin.
However, blood sugar can be high for various other reasons. Illness or injury, hormone disorders, overeating, obesity, some medications can increase blood sugar levels.

What Is Low Blood Sugar
Hypoglycaemia is a condition wherein blood sugar levels are too low. This condition affects a number of diabetic people when their bodies do not have enough glucose to use as energy. Hypoglycaemia is commonly the result of taking too much of the medication/s prescribed to treat diabetes, eating less than expected, exercising more than normal or skipping meals.
Some of the symptoms of hypoglycaemia include:
- A pale face
Make A Note Of Your Readings
It may sound obvious, but you must record your readings. Note them down in a diary, a notebook or in your phone calendar. Some meters have software that lets you do this. You could try a diabetes app too.
You and your healthcare team can then look back over your results to see if you need to adjust your treatment.

Managing Blood Sugar Levels
Many people with diabetes must check their blood sugar levels daily with a glucose meter. This device takes a drop of blood, usually from a finger, and displays the sugar level within a few seconds.
People with type 1 diabetes will need to take insulin as their doctor recommends, usually several times a day.
Those with type 2 diabetes or gestational diabetes may need to change their diet and exercise habits. They may also need to take oral medications or insulin.
A number of strategies can help prevent hyperglycemia.
People should:
- check their blood sugar levels as their doctor advises and take the correct amount of insulin, if they have type 1 diabetes
- speak to their healthcare provider or dietitian about which foods to eat or avoid, how much to eat, and how often
- take precautions to avoid infections, for example, through regular hand washing, as illness, such as a cold, can trigger a rise in blood pressure
- plan their food intake and exercise to balance blood sugar levels
- minimize stress, as far as possible, for example, through exercise, getting enough sleep, and stress-reducing activities such as meditation or yoga
Low blood sugar, or hypoglycemia, can happen when a person:
- has certain medical conditions
- does a lot of exercise
- skips meals or eats too little
It can also be a side effect of diabetes medicines. Taking too much insulin can result in low blood sugar levels.
Symptoms of low blood sugar may include:
- visit a doctor regularly

Nighttime Low Blood Sugar
While low blood sugar can happen at any time during the day, some people may experience low blood sugar while they sleep. Reasons this may happen include:
- Having an active day.
- Being physically active close to bedtime.
- Taking too much insulin.
- Drinking alcohol at night.
Eating regular meals and not skipping them can help you avoid nighttime low blood sugar. Eating when you drink alcohol can also help. If you think youre at risk for low blood sugar overnight, have a snack before bed.
You may wake up when you have low blood sugar, but you shouldnt rely on that. A continuous glucose monitor can alert you with an alarm if your blood sugar gets low while youre sleeping.
What Are The Signs & Symptoms Of High Blood Sugar Levels
Signs of high blood sugar levels include:
- Peeing a lot: The kidneys respond by flushing out the extra glucose in urine. People with high blood sugar need to pee more often and in larger amounts.
- Drinking a lot: Someone losing so much fluid from peeing that often can get very thirsty.
- Losing weight even though your appetite has stayed the same: If there isn’t enough insulin to help the body use glucose, the body breaks down muscle and stored fat instead in an attempt to provide fuel to hungry cells.
- Feeling tired: Because the body can’t use glucose for energy properly, a person may feel unusually tired.

Treating Low Blood Sugar
You are at risk of having a low blood sugar reaction if you:
- Skip or delay a meal or snack
- Take too much insulin or eat too few carbohydrates
- Exercise
- Drink alcohol, especially without eating carbohydrates
Check your blood sugar if you have any of these symptoms:
- Weakness and/or fatigue
If your blood sugar is less than 70 milligrams per deciliter :
- Eat 15 to 30 grams of carbohydrate
- Wait 15 minutes and then recheck your blood sugar
- If your blood sugar is still less than 100 mg/dl, take another 15 grams of carbohydrate and retest your blood sugar in another 15 minutes. Repeat if necessary.
Important: If you have frequent low blood sugars speak to your doctor. You may need changes in your medication and/or meal plan.
What Is The Outlook For People With Hypoglycemia

Hypoglycemia can be managed when you and your healthcare provider understand what causes your blood sugar to go down. Give your healthcare provider as much information as possible about any hypoglycemic episodes. Fixing the problem may be as simple as changing the times you take medication, eat and exercise. Minor changes to the types of food you eat may also help.

The Best Healthcare Options To Prevent Diabetes
Health care is expensive. Canada spent an estimated $253.5 billion in 2018, and as the cost of health care increases, so does the cost to you. Pre-existing medical conditions, family history, and BMI are all factors that increase the cost of health care. These factors also increase your risk of diabetes, so you must be covered.
Of course, as a Canadian, you are entitled to some free and subsidized health care, which is great. But many people opt for private healthcare and for diabetes prevention this can be very useful. If you’re shopping around for private healthcare, it’s important to choose the right package.
Basic health insurance will usually cover health care, medical services, and prescriptions, but they tend to lack customizations. If you opt for a premium/guaranteed health insurance you have the bonus of a custom plan based on your needs if you are worried about your risk of diabetes this is like gold dust.
Private healthcare plans can cover the cost of many expenses related to diabetes such as blood tests, blood sugar monitors, specialist referrals, hospital stays, and much more! The most important thing to note about private health care is that it covers costs for preventative care, not just treatment for diseases.
There are many different options available, so make sure you search for the best quotes.
How To Do A Finger
Your healthcare team will show you how to do it the first time, but these are the key steps:
- Wash your hands with soap and warm water. Dont use wet wipes as the glycerine in them can affect the test result. Make sure your hands are warm so its easier to get blood and wont hurt as much.
- Take a test strip and slot it into the meter to turn it on. Some meters will have tests strips built in.
- Remove the cap from your finger prick device and put in a new lancet. Then put the cap back on and set the device by pulling or clicking the plunger.
- Choose which finger to prick but avoid your thumb or index finger . And dont prick the middle, or too close to a nail. Place the device against the side of your finger and press the plunger. Use a different finger each time and a different area.
- Take your meter with the test strip and hold it against the drop of blood. Itll tell you if the test strip is filled, usually by beeping.
- Before you look at your reading, check your finger. Use a tissue to stop bleeding, then use it to take out the lancet and throw it away in your sharps bin.
- You can use the same tissue to take out the test strip and throw that away too. Taking out the strip will usually turn the meter off.

Normal Range Of Blood Sugar Levels
The normal range of blood glucose levels for individuals with diabetes is between 70 and 130 milligrams per deciliter . When levels are too low, the person may experience hypoglycemia, which is characterized by shakiness, sweating, dizziness, or confusion. When blood sugar levels are too high, the person may experience hyperglycemia, which is characterized as extreme thirst and urination and blurred vision. Blood glucose levels can be checked by pricking a finger to get a drop of blood and putting it on a glucose meter.
The normal blood sugar range is between 80-120 mg/dL .
How Does High Blood Sugar Affect The Body
High sugar in the blood can lead to a number of other symptoms and complications. Here are just a few.
Urination and thirst: High blood sugar goes into the kidneys and urine. This attracts more water, causing frequent urination. This can also lead to increased thirst, despite drinking enough liquids.
Weight loss: High blood sugar can cause sudden or unexplained weight loss. This occurs because the bodys cells are not getting the glucose they need, so the body burns muscle and fat for energy instead.
Numbness and tingling: High blood sugar can also cause numbness, burning, or tingling in the hands, legs, and feet. This is due to diabetic neuropathy, a complication of diabetes that often occurs after many years of high blood sugar levels.

What Are Normal Blood Sugar Levels
They’re less than 100 mg/dL after not eating for at least 8 hours. And they’re less than 140 mg/dL 2 hours after eating.
During the day, levels tend to be at their lowest just before meals. For most people without diabetes, blood sugar levels before meals hover around 70 to 80 mg/dL. For some people, 60 is normal for others, 90.
What’s a low sugar level? It varies widely, too. Many people’s glucose won’t ever fall below 60, even with prolonged fasting. When you diet or fast, the liver keeps your levels normal by turning fat and muscle into sugar. A few people’s levels may fall somewhat lower.
The Blood Sugar Level Regulation Mechanism

When you eat rice, bread, or any other typical food high in carbohydrates, it is digested by the stomach and small intestine, where it is absorbed into the blood as glucose. Figure 1 shows how it is absorbed into the body.
Figure 1: Absorption of glucose
When glucose enters the bloodstream, insulin facilitates its uptake into the body’s cells. When an excess of glucose is ingested, insulin over secretion occurs. Insulin increases the biosynthesis of fat and suppresses its breakdown. Thus, it becomes easier for fat to accumulate in body tissues.
Blood sugar level will not drop if the sugar in the blood is not properly processed due to, for example, too little insulin being secreted, or resistance to the action of insulin. If blood sugar levels have not decreased several hours after eating on a regular basis, this indicates a susceptibility to diabetes. To avoid this and stay healthy, we should eat types of foods that will not cause a sudden, extreme rise in blood sugar levels.
