How Much Should Blood Sugar Rise After A Meal


Whats A Spike And Why Do They Happen

Clearing Up Myths About Blood Sugars After Eating

After-meal, or postprandial, spikes are temporary high blood glucose levels that occur soon after eating. It is normal for the level of glucose in the blood to rise a small amount after eating, even in people who do not have diabetes. However, if the rise is too high, it can affect your quality of life today and contribute to serious health problems down the road.

How Can I Check My Blood Sugar

Use a blood sugar meter or a continuous glucose monitor to check your blood sugar. A blood sugar meter measures the amount of sugar in a small sample of blood, usually from your fingertip. A CGM uses a sensor inserted under the skin to measure your blood sugar every few minutes. If you use a CGM, youll still need to test daily with a blood sugar meter to make sure your CGM readings are accurate.

Signs And Symptoms Of Diabetes

If you feel that you have been experiencing some of the below-mentioned symptoms, then there is a possibility that you may have diabetes. If so, we recommend you consult your doctor and get diagnosed at the earliest.

  • You urinate a lot, especially at night.
  • You feel thirsty a lot.
  • You feel numbness and tingling sensations in your hands or feet from time to time.
  • You lose weight frequently without really trying to lose it.
  • You suffer from blurry vision.
  • You suffer from infections frequently.
  • You feel hungry more often.
  • You quickly get tired and worn out.
  • You have dehydrated skin.
  • You suffer from sores that take more than usual time to heal.

People with type 1 diabetes also suffer from vomiting, abdominal pain, and nausea. Usually, Type 1 diabetes starts developing at a young age, but it can also happen at the lateral stage. People with type 2 diabetes are hard to diagnose because the symptoms are difficult to spot. Moreover, the symptoms of type 2 diabetes take years to develop. Type 2 diabetes is more likely to develop in adults, but children can also develop it in some cases. So, you must be wondering what is normal and diabetes blood sugar after eating?

Causes Of High Blood Sugar

It’s not typical for your glucose to remain elevated four hours after eating. By then, insulin should have done its job and made sure that all of that extra glucose was used up. So if your blood sugar is still high hours after eating, it could be a sign that you have diabetes. Or if you have already been diagnosed, the dosage of your insulin or other diabetes medication might be off. Elevated glucose can also stem from an infected pancreas, an overactive thyroid and certain types of tumors.

How Can I Treat High Blood Sugar

Blood Sugar After Eating  How to Manage it Better

Talk to your doctor about how to keep your blood sugar levels within your target range. Your doctor may suggest the following:

  • Be more active. Regular exercise can help keep your blood sugar levels on track. Important: dont exercise if ketones are present in your urine. This can make your blood sugar go even higher.
  • Take medicine as instructed. If your blood sugar is often high, your doctor may change how much medicine you take or when you take it.
  • Follow your diabetes meal plan. Ask your doctor or dietitian for help if youre having trouble sticking to it.
  • Check your blood sugar as directed by your doctor. Check more often if youre sick or if youre concerned about high or low blood sugar.
  • Talk to your doctor about adjusting how much insulin you take and what types of insulin to use.

Ways To Better Control Blood Sugar After Eating

Do you find it difficult to stabilize your blood sugar levels after eating? Follow these mealtime tips to help keep your blood sugar in range.

When you have type 2 diabetes, life can often feel like a juggling act: You have to balance how much you eat, and when you eat it, with the right amount of exercise all while taking your medications consistently. Strike a good balance and your blood glucose can remain stable. If you don’t make it work, your risk of diabetes complications rises.

Food makes your blood sugar levels rise soon after eating. The particular food you eat, how much you eat, and the timing of your medication around the time you eat make a difference in your levels, too.

Damage to your body from high blood sugar can happen pretty quickly, and the higher the level, the greater your risk of complications, according to a 2015 review in the Diabetes & Metabolism Journal. The higher the blood sugar levels reach, the more likelihood for damage to vessels and other parts of the body.


And problems can develop when the numbers stay high for just a few days, according to the Joslin Diabetes Center in Boston. The specialty medical center advises making changes to your treatment plan if blood glucose levels stay over 180 mg/dl for three days in a row.

Strike The Spike Ii: How To Manage High Blood Glucose After Meals

Dealing With High Blood Sugar After Meals


Several years ago, I wrote an article for Diabetes Self-Management about the management of high blood glucose after meals. It was called Strike the Spike and no article Ive ever written has led to greater reader response. To this day, I still receive calls and e-mails thanking me for offering practical answers to this perplexing challenge. Ive even been asked to speak on the topic at some major conferences. So when presented with the opportunity to readdress the issue, I jumped at the chance.

A lot has changed in recent years: we know more than ever about the harmful effects of after-meal blood sugar spikes, but we also have a number of potent new tools and techniques for preventing them. And now that I know how meaningful this topic is to so many people, Ill do my absolute best to provide some answers.

How Common Is Low Blood Glucose

Blood Sugar Levels After Eating

Low blood glucose is common among people with type 1 diabetes and among people with type 2 diabetes who take insulin or some other diabetes medicines. In a large global study of people with diabetes who take insulin, 4 in 5 people with type 1 diabetes and nearly half of those with type 2 diabetes reported a low blood sugar event at least once over a 4-week period.2

Severely low blood glucose, defined as when your blood glucose level drops so low you cant treat it yourself, is less common. Among U.S. adults with diabetes who take insulin or some diabetes medicines that help the pancreas release insulin into the blood, 2 in 100 may develop severely low blood glucose each year.3

Choose The Healthiest Carbohydrates

Of the major nutrients found in food carbs, protein, and fat carbs have the biggest effect on your blood sugar. Thats because carbs are the most quickly broken down into glucose for energy. Having too many carbs, or the wrong type of carbs, can lead to spikes in your blood sugar.

The best way to figure out how the carbs you eat affect your blood sugar is to test your levels before and after meals. The American Diabetes Association recommends keeping track of the number of carbs you have per meal. The amount you should eat may vary depending on what it looks like to successfully manage your diabetes. Choose healthy, complex carbs such as whole fruits and vegetables, whole grains, beans, and lentils. Because they contain fiber and are less processed, these foods dont lead to as many swings in your blood sugar levels. Stay away from refined carbs such as soda, candy, white pasta, white rice, white bread, and other processed foods they can cause blood sugar to rise quickly.

Exercise And Blood Sugar

Exercise can have a big effect on your blood sugar levels because blood sugar is used for energy. When you use your muscles, your cells absorb sugar from the blood for energy.

Depending on the intensity or duration of exercise, physical activity can help lower your blood sugar for many hours after you stop moving.


If you exercise regularly, the cells in your body may be more sensitive to insulin. This will help keep blood sugar levels within normal ranges.

When To Seek Medical Care For High Blood Sugar

If hyperglycemia persists for at least two or three days, or if ketones appear in the urine, call a doctor.

Generally, people with diabetes should test their blood sugar levels at least four times a day: before meals and at bedtime . The urine should be checked for ketones any time the blood sugar level is over 250 mg/dL.

When blood sugar stays high despite following a diabetic diet and plan of care, call the nurse, diabetes health educator, or physician for adjustments in the diet.


If blood sugars are high because of illness, check for ketones and contact a health professional.

Seek immediate medical care for these conditions:

  • Vomiting
  • Blood sugar levels that stay above 160 mg/dL for longer than a week
  • Glucose readings higher than 300 mg/dL
  • The presence of ketones in the urine

Ketoacidosis or diabetic coma is a medical emergency. Call 911 for emergency transport to a hospital or similar emergency center.

How Much Does Blood Sugar Increase After Eating

Blood Sugar Normal

At this time the blood sugar level can reach 7.8 mmol/L in a healthy individual.

After the half-hour mark, the blood glucose level starts to fall as the sugar is absorbed from the blood into the cells of the body.

Its important to check your normal blood sugar level 1 hour after eating. For example, if you find that your blood sugar is 160 mg/dL after the meal, this equates to 8.9 mmol/L which means your blood sugar is high. Its an indication that you may need to seek medical treatment to control your blood sugar level.

Who Should Monitor Blood Sugar Levels

If you have type 1 or type 2 diabetes, monitoring your blood sugar regularly will help you understand how medication like insulin, food, and physical activity affect your blood glucose. It also allows you to catch rising blood sugar levels early. It is the most important thing you can do to prevent complications from diabetes such as heart attack, stroke, kidney disease, blindness, and amputation.

Other people who may benefit from checking their blood glucose regularly include those:

  • Taking insulin

Beware Of The Label Sugar

Grocery shopping can be confusing, since at first glance, many foods may seem healthier than they are. Smart food choices can be hard to make. Watch out for sugar-free alternatives, which are better than the real-sugar versions, but hardly healthy.

In addition, says Champion, just because a food is labeled sugar free, reduced sugar, or no sugar added doesnt mean its carbohydrate free, too. This means the food can still cause your blood sugar to rise. Your best bet is to look at the Nutrition Facts panel and ingredient label on the back of the package, she says. Dont rely on advertising claims on the front of the package.


The ADA suggests that rather than just looking at the sugar content, always check the total amount of carbohydrates in a product which includes the amounts of starch, fiber, sugar, and sugar alcohols. This total will give you a more accurate idea of how a food may actually affect your blood sugar levels.

What If I Have Severe Low Blood Glucose And Cant Treat Myself

Glucagona hormone that raises blood glucose levelsis the best way to treat severely low blood glucose. Available as an injection or a nasal spray, glucagon will quickly raise your blood glucose level. Your doctor can prescribe you a glucagon kit for use in case of an emergency.

If your blood glucose level drops very low, you wont be able to treat it by yourself. Be prepared to address severely low blood glucose by

  • talking with your doctor or health care team about when and how to use a glucagon emergency kit. If you have an emergency kit, regularly check the date on the package to make sure it hasnt expired.
  • teaching your family, friends, and coworkers when and how to give you glucagon. Tell them to call 911 right away after giving you glucagon or if you dont have a glucagon emergency kit with you.
  • wearing a medical alert identification bracelet or pendant. A medical alert ID tells other people that you have diabetes and need care right away. Getting prompt care can help prevent the serious problems that low blood glucose levels can cause.

The Blood Sugar Level Regulation Mechanism

Blood Sugar Levels Chart | Includes fasting and after eating

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

  • 1The sugar in food is absorbed into the blood as glucose.
  • 2The pancreas secretes insulin in reaction to the increase in glucose.
  • 3Because the glucose is absorbed into the liver, muscle, adipose tissue and other cells, the blood sugar level drops to the level it was before anything was eaten. This is the mechanism found in healthy people.
  • 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.

    If your blood sugar is too low, the best thing to do is to eat a balanced meal based on the data youve collected since you started tracking your blood sugar after eating.

    If you dont have enough data just yet, start with something thats moderate in carbohydrate and also contains some protein and healthy fats. An apple with some nut butter is a good option, as is meat or seafood with some vegetables cooked in olive oil.


    Clearly, theres a huge range in the effects different types of food have on your blood sugar.

    Thats why tracking your blood sugar 1 hour after eating and your blood sugar 3 hours after eating over a few weeks can be such a valuable tool.

    When youre learning how to improve your blood test results and optimize your long term health and longevity, you must have data as the foundation.

    Your blood sugar is one of the fundamental indicators of your current and future health, and if you focus on this one metric alone, all the other biomarkers in your annual labs are likely to improve as well.

    How Do I Check Blood Sugar Level

    Checking blood sugar level is very simple thanks to the availability of easy-to-use handheld glucometers. These consumer glucometers have made it very easy to always keep an eye on your blood sugar level. They are an absolute essential for diabetics and also for people trying to maintain their blood glucose level.

    They operate by taking pin-pricks of blood onto a small electrode slip, which when inserted into the device gives a digital readout of the amount of glucose content in the blood. These devices have become extremely popular for their convenience, reliability and accuracy.

    An essential laboratory test of blood glucose level is the Oral Glucose Tolerance Test or OGTT. It is a diagnostic test for DM or any glucose intolerance. Here, a blood sugar reading is taken after a 10-12 hour fast. Then another reading is taken after 2 hours after ingesting a measured amount of glucose. This test shows the bodys ability to absorb glucose, thus is a confirmatory test for DM.
