Blood glucose levels normally rise after a high-carbohydrate meal and drop back to normal levels within a few hours. But if your glucose levels rise higher than normal and recover more slowly, you might have diabetes. Your doctor can administer tests that measure your blood glucose levels immediately before you consume a high-carbohydrate meal and for several hours afterward. If you already have diabetes, your doctor might want you to check your blood glucose levels after meals, to make sure you’re keeping your glucose within the expected range.

Symptoms Of Low Blood Sugar

  • Hunger
  • Sleepiness
  • Weight fluctuations

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 To Test Your Blood Sugar

To test your blood sugar at home, all you need is a very inexpensive piece of equipment you can find at any drug store or pharmacy called a glucose meter or glucometer.

Glucose testing from home using a glucometer is typically done by a finger stick test. This involves pricking the tip of your finger and collecting a small drop of blood onto the testing strip.

The test itself is very mildly painful but if you are feeling squeamish, I recommend having someone else help you with the finger stick because it may be harder to do on yourself.

Here are the data points that you will want to track when assessing your bodys response to meals: :


  • fasting blood sugar levels
  • blood sugar 1 hour after eating
  • blood sugar 2 hours after eating
  • blood sugar 3 hours after eating
  • how long it takes for blood sugar to return to fasting levels after eating
  • a diary of foods eaten before the tests

Lets work through the best way to test your blood sugar and get all these data points.

First: Test your blood sugar first thing in the morning before you have eaten anything.

This is called your fasting blood sugar level. Optimally this level should be between 82-88 mg/dL . Conventional medicine considers anything < 100 mg/dL as normal.

Second: Test your 1-hour post-meal blood sugar.

Third: Test your 2-hour post-meal blood sugar.


This reading tells you how efficient your body is at balancing your blood sugar. Optimally this level should be less than 120 mg/dL . The closer to 100, the better.

Why Are Blood Sugar Spikes A Problem

How long after a meal will blood sugar levels return to ...

Even though the spike is temporary, all of those spikes throughout the day can raise your HbA1c. Research has shown that for those with an A1c below 7.5%, post-meal readings actually have a greater influence on A1c than fasting blood sugars. In other words, managing pre-meal readings will only get you so far. If you want tight control, you need to pay attention to the after-meal glucose as well.

The long-term effects of postprandial hyperglycemia have been studied extensively. For those with type 1 diabetes, significant post-meal rises have been shown to produce earlier onset of kidney disease and accelerate the progression of existing eye problems . And like a dagger through the heart, post-meal hyperglycemia is an independent risk factor for cardiovascular problems. Recently, post-meal spikes and glucose variability have been associated with diminished brain function and an increased risk of dementia.

But the problems are not limited to long-term health issues. Any time blood sugars rise particularly high, even temporarily, our quality of life suffers. Energy decreases, cognitive ability falters, physical/athletic abilities become diminished, and moods become altered. And dont forget: What goes up must come down. The rapid blood sugar decline that usually follows a post-meal spike can cause false hypoglycemic symptoms.

Time Your Bolus Insulin Properly

For people who take rapid-acting insulin at mealtimes, the timing of the bolus can have a huge impact on after-meal blood glucose levels. Boluses given too late to match the entry of glucose from dietary carbohydrates into the bloodstream can produce significant blood glucose spikes soon after eating. A properly timed bolus, on the other hand, can result in excellent after-meal control.

Unless you have gastroparesis , it is best to give bolus insulin doses before eating. How long before? It depends mainly on what you are eating and on your pre-meal blood glucose level.

Figuring out the pre-meal blood glucose part is fairly straightforward: the higher your blood glucose, the earlier the bolus should be given. If your pre-meal blood glucose is well above your target, it is best to give the bolus and then wait at least 30 minutes before eating. Near your target blood glucose? Wait 15 minutes. Below target? Either take the bolus and eat right away, or take the bolus after eating to manage high blood glucose.

Does earlier bolusing make a difference? Absolutely. Research has shown that simply giving mealtime boluses before eating rather than after eating can reduce the post-meal spike by about 45 mg/dl.

Time To Strike High Blood Glucose

Given the many short- and long-term benefits of post-meal blood glucose control, it is certainly worth the effort to start measuring and evaluating your after-meal control. If your blood glucose levels are higher than they should be, talk with your healthcare team about new or different medical treatments that might help. And take a look at your personal choices in terms of food and activity. Even without a perfectly functioning pancreas, there is still a multitude of options for tackling those high blood glucose spikes!

Low Blood Sugar Levels In Diabetes

People with diabetes can have low blood sugar levels because of the medicines they have to take to manage their diabetes. They may need a hormone called or diabetes pills to help their bodies use the sugar in their blood.


These medicines help take the sugar out of the blood and get it into the bodys cells, which makes the blood sugar level go down. But sometimes its a tricky balancing act and blood sugar levels can get too low.

People with diabetes need to keep their blood sugars from getting too highor too low. Keeping blood sugar levels in a healthy range means balancing when and what they eat, and when they exercise with when they take medicines.

What Is Blood Sugar

What should be the blood sugar levels after 30 mins of food intake? – Dr. Mahesh DM

Blood sugar, also known as blood glucose, comes from the food you eat. Your body creates blood sugar by digesting some food into a sugar that circulates in your bloodstream.

Blood sugar is used for energy. The sugar that isnt needed to fuel your body right away gets stored in cells for later use.

Too much sugar in your blood can be harmful. Type 2 diabetes is a disease thats characterized by having higher levels of blood sugar than whats considered within normal limits.


Unmanaged diabetes can lead to problems with your heart, kidneys, eyes, and blood vessels.

The more you know about how eating affects blood sugar, the better you can protect yourself against diabetes. If you already have diabetes, its important to know how eating affects blood sugar.

Your body breaks down everything you eat and absorbs the food in its different parts. These parts include:

  • carbohydrates
  • fats
  • vitamins and other nutrients

The carbohydrates you consume turn into blood sugar. The more carbohydrates you eat, the higher the levels of sugar youll have released as you digest and absorb your food.

Carbohydrates in liquid form consumed by themselves are absorbed more quickly than those in solid food. So having a soda will cause a faster rise in your blood sugar levels than eating a slice of pizza.


Fiber is one component of carbohydrates that isnt converted into sugar. This is because it cant be digested. Fiber is important for health, though.

Controlling Blood Glucose Levels

Uncontrolled blood sugar can result in regular episodes of hyperglycemia . This can cause a variety of symptoms including:

  • Dry mouth
  • Nausea
  • Fatigue

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.

The Effects Of Protein And Fat

The rate at which food leaves your stomach, called gastric emptying, affects the amount of sugar in your blood after you eat. Protein and fat both slow down gastric emptying, which helps keep blood sugar lower shortly after a meal. In a study published in 2016 in the journal Diabetologica, people who ate high protein-foods before eating carbohydrates , experienced a rise in glucagon, which is thought to play a role in slowing down gastric emptying.

Plus, says Palinski-Wade, “if you’re eating a meal that has a large amount of fat or protein, the fat, the protein or the fiber will slow down the absorption and conversion of the sugar, so the peak might be a bit delayed.” She suggests eating carbs with at least one good source of fiber, protein or fat. “Not only is it going to help with the release of blood sugar,” she says, “but it’s also going to help keep you more satisfied.”


Insulin And Blood Sugar

How long after eating should blood sugar rise (peak) and ...

Insulin is an important hormone that helps regulate your blood sugar levels. The pancreas makes insulin. It helps control your blood sugar levels by assisting the cells that absorb sugar from the bloodstream.

If you have type 1 diabetes, your body doesnt make insulin. This means you have to inject insulin every day.

If diet and exercise arent enough to manage blood sugar, those with type 2 diabetes may be prescribed medications to help keep blood sugar levels within target ranges.

If you have type 2 diabetes, your body produces insulin, but may not use it properly or produce enough of it. Your cells dont respond to insulin, so more sugar keeps circulating in the blood.

Exercise can help the cells respond better and be more sensitive to insulin. The proper diet can also help you avoid spikes in blood sugar. This can help keep your pancreas functioning well since high blood sugar levels decrease pancreatic function.

What Should My Blood Sugar Level Be

When you’re first diagnosed with diabetes, your diabetes care team will usually tell you what your blood sugar level is and what you should aim to get it down to.

You may be advised to use a testing device to monitor your blood sugar level regularly at home.

Or you may have an appointment with a nurse or doctor every few months to see what your average blood sugar level is. This is known as your HbA1c level.

Target blood sugar levels differ for everyone, but generally speaking:

  • if you monitor yourself at home with a self-testing kit a normal target is 4 to 7mmol/l before eating and under 8.5 to 9mmol/l 2 hours after a meal
  • if your HbA1c level is tested every few months a normal HbA1c target is below 48mmol/mol

The Story Of The Pima Indians

Research has found3 that the Pima Indians are a perfect example of how powerfully our environment can dictate who gets obese and diabetic, and who doesnt.

Today, two main groups of Pima Indians live on earth. The first group lives high in the Sierra Madre Mountains of Mexico a rural environment. The second group lives in Arizona on the Gila River reservation. Both groups are thought to be genetically identical. Scientists estimate they were separated about 700 to 1,000 years ago. For DNA evolutionary development, thats a mere pittance of time.

But physically, the two groups today could not be more different.

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.

What Is Normal Blood Sugar Levels After Eating For Non

Blood Sugar Levels Chart | Includes fasting and after eating

It would be remiss of me, if I left you hanging without letting you in on what normal blood sugars should be after eating if you are non-diabetic.

Whats the point of telling about blood sugar spikes in non-diabetics if I dont reveal what normal blood sugars should be after eating.

The essential point here though is the importance of non-diabetics having a control on their diet. What you eat has either a positive effect on your health or a negative one.

Let me repeat that.

Non-diabetics are obliged to take control of their food choices, if they are to avoid the health implications of blood sugar highs. This is the whole point of this exercise.

You may want to use the figures below as your non-diabetic blood sugar chart if you like. It works just the same way.

So, below is your non-diabetic blood sugar or glucose chart and this is what is recommended by the American College of Clinical Endocrinologists.

Of particular interes,t are the values there that represent what you, as a non-diabetic should be aiming for at 1 hour after eating and 2 hours post meal. They represent what should be normal blood sugar levels after eating your meal.

As you can see it is anticipated that your blood sugar should peak 1 hour after you have eaten but some foods may swing either way.

For instance, an oatmeal may peak just beyond the 1-hour mark compared to a bagel, doughnut or potato fries which might peak much earlier.
