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
When It’s Time To Call A Doctor
If any of the symptoms mentioned have begun to impact your life, such as fatigue so severe you can’t stay awake through the day, it’s a good idea to consult your physician. Dr. Fruge warns that “unstable blood sugar levels could put you at higher risk of heart disease and stroke and it is a red flag for serious health issues” — so blood sugar issues should be taken seriously.
You should also see a doctor if you’re experiencing symptoms of hypoglycemia and haven’t been diagnosed with diabetes or any other underlying condition.
If you do have diabetes and your hypoglycemia isn’t responding to the treatments described above, that’s another good cue to call your health care provider.
If testing reveals you have Type 1 diabetes, you’ll need to continue to test your blood sugar levels as often as instructed by your physician, take insulin regularly and participate in regular exercise. This may mean you will need a new glucose monitoring system, so ask your doctor what they recommend. If you’re diagnosed with Type 2 diabetes, you’ll most likely need to do the same as for Type 1, as well as working with health care professionals to make lifestyle changes such as improving nutrition and planning workouts. Medication may be necessary as well.
Healthy eating, regular exercise and other lifestyle changes can help alleviate symptoms and possibly even reverse prediabetes.
A Few Final Notes On Keeping Blood Sugar Stable
Taking an active, intentional approach to your blood sugar levels is crucial to your quality of life and overall health, ONeill says. Avoiding too-high or too-low blood sugar levels will help you avoid adverse symptoms and health complications, and staying within your target range can enable you to feel your best and do whatever you want to do in life, she says.
Test your blood sugar regularly, listen to your body, and dont ever hesitate to reach out to your doctor.

Blood Sugar Levels And Diabetes
If you have diabetes, you may be wondering what your blood glucose should be. Hopefully your doctor, nurse practitioner, physicians assistant or whoever diagnosed you has given you answers to that question. Unfortunately, though, not everyone is given glucose goals. Or in some cases, it may have been a long time ago, and theyve since been forgotten. No worries well go over all that!
Blood Sugar Testing At Home
A person can test their blood sugar levels at home.
In most cases, doctors ask people to measure fasting blood sugar immediately upon waking and before they have anything to eat or drink. It may also be appropriate to test blood sugar before eating or 2 hours after a meal, which is when blood sugar returns to normal levels.
The right time to test depends on treatment goals and other factors. For example, most people with diabetes do not need to test between meals unless they are using a diabetes drug that can lower blood sugar. Other people may test between meals if they feel their sugar levels may be low.
Since people with type 1 diabetes do not make any insulin, they need to test their blood sugar levels several times a day so they can adjust their insulin doses.
A person will test blood sugar levels by:
- preparing the testing strip and glucose monitor to be ready for the blood sample
- using an alcohol swab to clean the testing area, which is usually the side of a fingertip
- lancing the testing area and bracing against a firm surface to help resist the impulse to pull away
- squeezing the testing area around the wound to maximize blood flow
- squeezing a drop of blood onto the test strip
- putting the strip into the monitor
- recording the time, blood sugar reading, and recent food intake in a log
Are Low Blood Sugar Levels Dangerous
Yes, low blood sugar symptoms can cause problems such as hunger, nervousness, perspiration, dizziness and even confusion if untreated, low blood sugar may result in unconsciousness, seizures, coma, or death. Low blood sugar levels begin at 70 mg/dL or less. People with diabetes who take too much medication or take their usual amount but then eat less or exercise more than usual can develop hypoglycemia. Although much rarer, hypoglycemia may develop in some people without diabetes when they take someone elses medication, have excessive alcohol consumption, develop severe hepatitis, or develop a rare tumor of the pancreas . The treatment for hypoglycemia is oral glucose intake (15. 0 grams of sugar, for example, 1 tablespoon of sugar, honey, corn syrup, or IV fluids containing glucose. Recheck your blood sugar levels in about 15 minutes after treatment is advised.
How To Treat A Low Blood Sugar Level Yourself
Follow these steps if your blood sugar level is less than 3.5mmol/L or you have hypo symptoms:
You do not usually need to get medical help once you’re feeling better if you only have a few hypos.
But tell your diabetes team if you keep having hypos or if you stop having symptoms when your blood sugar level is low.

What Is Normal Blood Sugar Levels Chart
Blood sugar or glucose is released after consumption and breakdown of carbohydrates during food intake. It is the main sugar that is found in your bloodstream and its regulation is undertaken by pancreatic secretions . Normal blood sugar levels chart for most adults ranges from 80 to 99 mg of sugar per deciliter before a meal and 80 to 140 mg per deciliter after meals.
What You Can Drink With Meals
Add a low-calorie, low-sugar drink or choose water. Proper hydration is essential to helping your body remove excess sugar.
Some drinks that are good for keeping your blood sugar level low include:
- Unsweetened tea
- Sparkling water or club soda
- Flavored water or sparkling water without added sugar

Act Quickly To Treat The Situation
If you suspect you have low blood sugar, Dr. Fruge recommends quickly treating the situation, which she says should include “eating healthy foods such as complex carbohydrates, beans or fruit.”
“At the Pritikin Longevity Center we serve a cup of fruit with a cup of veggies to prevent a spike in insulin, which can sometimes lead to a later drop in blood sugar again,” she explains. “Adjusting your diabetes medication as prescribed by your physician may also be necessary. It’s important to retest your blood sugar 20 minutes after eating to confirm it has improved.”
Keep a fast-acting carbohydrate snack or two on hand in case your blood sugar dips below healthy levels.
How Can I Tell If My Blood Sugar Is Irregular
Again, only a doctor can diagnose a problem with your blood sugar. But you may be wondering how to know if it’s something you should get checked out. There can be two main issues with your blood sugar — either it’s consistently too high or too low. Even if you don’t have diabetes, there are some signs that your blood sugar levels are not functioning normally.
Hypoglycemia is a condition in which your blood sugar is too low. Signs include an irregular heartbeat, fatigue, shakiness and tingling or numbness in your face. If you consistently feel this way when you get hungry or between meals, talk to your healthcare provider.
On the flipside, hyperglycemia happens when your blood sugar is too high, and can happen to nondiabetics. Symptoms include frequent urination, increased thirst and headache. If you think you’re hyperglycemic and can’t keep fluids or food down, call for emergency medical assistance.

What Causes Low Blood Glucose In People With Diabetes
Low blood glucose levels can be a side effect of insulin or some other medicines that help your pancreas release insulin into your blood. Taking these can lower your blood glucose level.
Two types of diabetes pills can cause low blood glucose
- sulfonylureas, usually taken once or twice per day, which increase insulin over several hours
- meglitinides, taken before meals to promote a short-term increase in insulin
The following may also lower your blood glucose level
What Should I Do With The Data
When keeping track of your results, make sure to include the time and date, blood glucose results. Additional notes about what you ate, whether you exercised, any difficulty with illness and stress, medications, and doses you are taking can be helpful. You should discuss your results with your diabetes educator on a frequent basis to determine what they represent and whether you need to make any adjustments to better control your blood sugar.

How To Test Your Blood Sugar At Home
To perform a blood sugar test, you will need to prick your finger with a lancet . Youll put a small sample of blood from this onto a strip inserted into the blood glucose meter.
Before you test your blood sugar at home, its important to find out from your doctor what a healthy blood sugar range is for you. Your doctor will determine this range based on factors such as:
- the type of diabetes you have
- how long youve had diabetes
- your age
- whether you have any other chronic health conditions
If you dont have a blood sugar testing machine on hand and are experiencing signs or symptoms of low blood sugar with diabetes, your symptoms may be enough to diagnose low blood sugar.
Now That Youre Checking Your Blood Glucose What Do The Numbers Mean
Depending on your diabetes treatment plan, your doctor or diabetes educator may advise you to check once a week, once a day or up to 10 times a day . But what does it mean when you see a 67, 101 or 350 on your meter? And what is a normal blood sugar, anyway? Great questions! After all, if you dont know what the numbers on your meter mean, its hard to know how youre doing.
The American Diabetes Association provides guidelines for blood glucose goals for people with diabetes, and the goals vary depending on when youre checking your glucose:
Fasting and before meals: 80130 mg/dl
Postprandial : Less than 180 mg/dl
By the way, these guidelines are for non-pregnant adults with type 1 or type 2 diabetes. Children, adolescents and pregnant women may have different goals.
Your blood glucose goals may be different, however. If youre younger, have had diabetes for a shorter amount of time or are not taking any medicine for your diabetes, your glucose goals might be a little tighter, or lower. Likewise, your blood glucose goals may be higher than what ADA recommends if youre older, have diabetes complications, or dont get symptoms when your blood glucose is low.
Bottom line: talk with your health-care provider about the following:

What Is Diabetic Ketoacidosis
If you think you may have low blood sugar, check it even if you dont have symptoms.
When too many ketones are produced too fast, they can build up in your body and cause diabetic ketoacidosis, or DKA. DKA is very serious and can cause a coma or even death. Common symptoms of DKA include:
- Fast, deep breathing.
- Nausea and vomiting.
- Stomach pain.
If you think you may have DKA, test your urine for ketones. Follow the test kit directions, checking the color of the test strip against the color chart in the kit to see your ketone level. If your ketones are high, . DKA requires treatment in a hospital.
DKA happens most in people with type 1 diabetes and is sometimes the first sign of type 1 in people who havent yet been diagnosed. People with type 2 diabetes can also develop DKA, but its less common.
