Insulin And Blood Sugar

Clearing Up Myths About Blood Sugars After Eating

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 Are Normal Blood Sugar Levels After Eating

Your blood sugar level is influenced by several factors, including the food you eat. During digestion, carbohydrates are converted into sugar which your body uses as an energy source. Excess sugar from any source is stored in your cells for later use. When your cells contain too much sugar, though, it can lead to type 2 diabetes. This is why eating a balanced diet to maintain a normal blood sugar range is important.

Blood sugar levels can vary based on many factors, including age and life expectancy, comorbidities like heart disease, stress, and lifestyle factors like physical activity, smoking, or drinking alcohol.

Normal Postmeal Blood Sugar Levels

Checking your blood glucose one to two hours after eating can help you understand how your blood sugar reacts to the food you consume. It can also offer insight into whether you’re taking the right dose of insulin or if you need to follow up with your healthcare provider to discuss medication and diet or lifestyle adjustments.

There are two ways you can measure your blood glucose levels: by pricking your fingertip using a glucometer or by using continuous glucose monitoring. How often you should check your glucose levels varies from a few times per week to four to six times each day. As a general rule, the American Diabetes Association recommends keeping blood sugar below 180 mg/dL one to two hours after eating.


However, your target blood sugar range will depend on the following:

  • Duration of diabetes

Misusing Lancets And Test Strips

For the least pain and the most accurate results, you need the right blood sugar testing supplies: lancets, an accurate glucose meter, and manufacturer-recommended test strips. Skimping may not offer you the payoff you’re hoping for lancets start out very sharp but quickly get dull and will hurt if you try to reuse them, says Amori. Also, using expired or poorly stored test strips can result in inaccurate readings.

Solutions for better diabetes control: Use a fresh lancet, make sure test strips are stored in a closed container, and check the test strip expiration date before using.

Your Blood Sugar Isnt Just Because Of What You Eat

how to lower sugar level after eating

Mainstream media would have you believe that your blood sugar levels are impacted only by what you eat and how much you exercise, but people with type 1 and type 2 diabetes who test their blood sugars frequently could tell you otherwise.


Its especially important to keep this mind when looking at your own blood sugars and your goals because there are certain variables and challenges that impact blood sugar levels that you cant always control.

For example:

  • Menstrual cycles: raises blood sugar and insulin needs
  • Adrenaline rushes from competitive sports, heated arguments, rollercoaster rides: raises blood sugar and insulin needs
  • The common cold and other illnesses: usually raises blood sugar and insulin needs
  • Hormonal changes due to puberty and healthy growth in young adults: raises blood sugar and insulin needs
  • An injury which raises overall inflammation levels: raises blood sugar and insulin needs
  • Glucogenesis during anaerobic exercise: raises blood sugar

While you cant necessarily prevent these factors that affect your blood sugar from occurring, you can work with your diabetes healthcare team to adjust your insulin, other diabetes medications, nutrition and activity levels to help compensate for them when they do occur.

For example, when engaging in anaerobic exercise like weightlifting many people with type 1 diabetes find it necessary to take a small bolus of insulin prior to or during their workout because anaerobic exercise can actually raise blood sugar.

What Is Low Blood Sugar

Low blood sugar is a level of sugar, or glucose, in the blood that is lower than normal. According to the American Diabetes Association, the cut-off value for Level 1 hypoglycemia, or moderately low blood sugar, is 70 mg/dl. However, you may not be regularly measuring your blood sugar if you have not been diagnosed with diabetes. Instead, you might suspect that you have hypoglycemia because of its symptoms. The fatigue, fuzzy thinking, and need to sit down are the result of your body being deprived of its main fuel source: glucose.

Why Is Blood Sugar Checking Important

If you live with diabetes, a blood sugar check is paramount to good control. Without knowing your blood glucose numbers, you cannot appropriately dose insulin, treat a low blood sugar, eat a meal, or exercise with ease.

Think of a blood sugar check as a litmus test: the number isnt good or bad, it just gives a person with diabetes feedback on what they need to do next.

If a number is too high , its telling you to take some insulin or get some exercise, whereas if a number is too low, youll need to treat with sugar or some other form of glucose.

If your number is satisfactory, then you can proceed on with your day as planned.


Checking your blood sugar is also important to track long-term goals, like an hba1c test, and to see if youre reaching or even exceeding those goals.

Regularly checking your blood sugar also can give you feedback on whats working and whats not: maybe a particular food isnt working for your management goals, or a type of exercise, like yoga, has really helped to mellow out your blood sugar levels.

Its a good time to check in with yourself and calibrate your management to find what will work best for you, knowing that this can and will change over time.

Rebound Hypoglycemia After Eating

Blood Sugar Levels After Eating

If sugar comes from the food you eat, why would blood sugar be low after eating? It may be due to a phenomenon called reactive hypoglycemia. This refers to low levels of blood glucose that react to high levels. According to Mayo Clinic, it can occur within 4 hours of eating a meal.

Say breakfast includes pancakes, syrup, and fruit juice. The meal is full of carbs: starch in the pancakes, added sugar in the syrup, and natural sugar in the fruit juice. Those carbohydrates get absorbed fast.


Blood sugar can skyrocket, especially in people who have prediabetes or diabetes. You may feel a sugar high, or burst of energy, within minutes to an hour of eating. Thenthe crash. The higher they fly, the harder they fall, is spot-on for blood sugar. If it went up, up, up, it will go down, down down, possibly below normal levels and into the range of hypoglycemia.

How To Test Blood Sugar

People with diabetes usually check their blood sugar levels themselves. However, its a good idea to have a roommate, friend, or family member also know how to do it if you are sick and cant do it yourself.

To use a blood sugar meter, follow these steps:

  • Wash your hands.
  • Insert a test strip into the meter.
  • Obtain a drop of blood by pricking the side of your fingertip with the device.
  • Place the edge of the test strip to the blood and await the results to appear on the display.
  • If you are interested in CGM, you should talk to your healthcare provider since these are prescription devices. To use CGM, follow these steps:


  • Place the sensor under the skin on your belly or arm.
  • Most CGM devices check glucose levels every five minutes, around the clock. You dont need to do anything for this to occur.
  • View the information that the sensor transmits. This data may go to a separate receiver, your cellphone, or an insulin pump.
  • You will also need to change the sensors on the CGM regularly, usually every one to two weeks.

    How Can I Treat High Blood Sugar

    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.

    Who Gets Low Blood Sugar

    Low blood sugar can happen in people with prediabetes or diabetes, according to Mayo Clinic. If you are on insulin, it can happen if you take more insulin than you need, skip a meal, or eat fewer carbohydrates than usual without adjusting insulin. If you are not on insulin, or have diabetes but do not know it, low blood sugar can also happen if you skip a meal. It can also happen if you exercise more than usual.

    Low blood sugar is also more likely after eating meals that are high in starches and sugars because these are types of carbohydrates that raise blood sugar levels quickly. The effect is greater if the meal is low in protein, fat, and fiber, since those nutrients slow digestion and prevent blood sugar from swinging so wildly.

    Blood Sugar Testing Mistakes To Avoid

    1 / 8 Understand Diabetes Testing If you have diabetes, it’s imperative that you learn to effectively self-test your blood sugar to keep your glucose levels in check. For example, results from a study of more than 5,000 people living with diabetes showed that even those people who don’t take medication for diabetes have better blood sugar control if they test regularly. The study participants’ risk of early kidney damage, strokes, and death from diabetes-related causes was also reduced by one-third. Of course, the accuracy of your results is tied to the accuracy of your checking and to your understanding of what all the numbers mean. “The most important point to me is that people are learning something from checking their blood sugar,” says Sacha Uelmen, RDN, CDE, director of nutrition for the American Diabetes Association. “Don’t just look at those numbers, write them down, and move on. If you have diabetes, take an active role in your health.” To get the most useful readings, learn these common blood sugar testing mistakes and how to avoid them.Continue reading > >

    Blood Sugar Level Immediately After Eating:

    Blood sugar level changes rapidly according to the intake of the meal. The normal blood sugar level before eating or during fasting is between 3.5 to 6.1 mmol/L.

    Normal blood sugar right after eating rises drastically as the digestive tract acts quickly to digest the food through mechanical actions, digestive enzymes and different hormones. So the blood glucose rises sharply during this time. The rate at which the blood sugar rises depends on the type of food, the amount is taken, the metabolic condition of the individual, etc.

    What Are Blood Sugar Targets

    A blood sugar target is the range you try to reach as much as possible. These are typical targets:


    • Before a meal: 80 to 130 mg/dL.
    • Two hours after the start of a meal: Less than 180 mg/dL.

    Your blood sugar targets may be different depending on your age, any additional health problems you have, and other factors. Be sure to talk to your health care team about which targets are best for you.

    How Food Affects Blood Sugar

    When you eat food, your body breaks it down into essential parts:


    • Carbohydrates
    • Fats
    • Vitamins and minerals

    All parts are necessary in a healthy diet, but the three types of carbohydrates are particularly important when it comes to your blood glucose level. While the general rule is that the more carbohydrates you eat, the higher your blood sugar level, not all three types of carbohydrates convert to blood sugar at the same rate.

    The foods that fit into each carb category include:

    • Starches, or complex carbohydrates: Starchy vegetables, dried beans, and grains
    • Sugars: Fruits, baked goods, beverages, and processed food items like cereals or granola bars
    • Fiber: Whole wheat products, chickpeas, lentils, berries, pears, and brussels sprouts

    The glycemic index helps you find out which foods can increase or help decrease blood sugar levels. Based on a scale ranging from 0 to 100, high-indexed foods are rapidly digested, absorbed, and metabolized, resulting in marked fluctuations in blood sugar levels, while low-indexed foods produce smaller fluctuations in your blood glucose.

    The American Diabetes Association advises adding lean sources of protein and heart-healthy fats to help reduce the overall glycemic impact of a meal or snack.

    What Should I Do After I Check My Blood Glucose

    Write the blood glucose number in a log book or on a log sheet , and:

    • Include all of your blood glucose numbers.
    • Write a comment if there is a reason the blood glucose is above or below target.
    • Take your blood glucose meter with you when you are away from home.
    • Know your blood glucose numbers when you call the clinic or the doctor.
    • Bring your blood glucose meter and blood glucose records to all your appointments.
    • Bring a list of any questions that you may have.
