What Is High Blood Sugar
A healthy human body thrives when blood sugar levels are generally between 70 to 130 mg/dL throughout the day. While everyone including non-diabetics will likely experience blood sugar levels above this range because of big meals, this is the general goal range.
With low blood sugars, theres one number for everyone that is considered low 70 mg/dL because dipping below this becomes dangerous for everyone. But high blood sugars are more complicated because being slightly above the goal ranges listed below doesnt equate to immediate danger and may actually be safer for some people based on other health conditions and their age.
According to the American Diabetes Asociation and the Mayo Clinic, optimal blood glucose levels are:
Blood sugar goals for a non-diabetic:
- Between 80 and 120 mg/dL for people age 59 and younger with no additional medical conditions
- Below 100 mg/dL when fasted
- Between 100 and 140 mg/dL for people age 60 and older if they have additional health conditions like heart disease, kidney disease, etc.
Blood sugar goals for a person with type 1 or type 2 diabetes:
- Between 80 and 130 mg/dL fasted
- Less than 180 mg/dL within two hours after meals
High blood sugar levels become dangerous when:
- Youre high for a consistent period of time, even when you wake up in the morning
- Youre running above 180 mg/dL on a regular basis
- Youre running above 250 mg/dL on a regular basis very dangerous

Symptoms Of High Blood Sugar
High blood sugars can come on slowly or quickly depending on the type of diabetes you have and the cause of that particular high.
In fact, your blood sugars may have been sitting at a higher-than-normal level for so long that you dont really even feel the symptoms of it at all.
Compared to low blood sugars , high blood sugars are much more difficult to spot or even notice. They also take longer to correct, and while they carry less immediate danger compared to lows, they have the potential to cause much more long-term damage throughout your entire body.
Lets take a closer look at the causes and symptoms of high blood sugar levels.
What Is A Normal Blood Sugar Level 1 Hour After Eating
Getting a normal blood sugar level one hour after eating is an important step in keeping your health. Having a high blood sugar level can affect your entire body, including your heart, brain, and muscles. It can also lead to other health problems, such as diabetes. It’s important to understand what your blood sugar level should be, and how to treat hypoglycemia, which is when your blood sugar level drops below normal.

For a person without any type of diabetes, blood sugar levels are generally between 70 to 130 mg/dL depending on the time of day and the last time they ate a meal.
Newer theories about non-diabetic blood sugar levels have included post-meal blood sugar levels as high as 140 mg/dL.
Here are the normal blood sugar ranges for a person without diabetes according to the American Diabetes Association:
- Fasting blood sugar : Less than 100 mg/dL
- 1-2 hours after a meal: Less than 140 mg/dL
- 2-3 hours after eating: Less than 100 mg/dL
Standing Is Good But Walking Is Better
The meta-analysis, , analyzed seven studies comparing the impact of sitting, standing and walking on the bodys insulin and blood sugar levels. People in the studies were asked either to stand or walk for two to five minutes every 20 to 30 minutes over the course of a full day.
Between the seven reviewed studies, the total activity time throughout the observation was roughly 28 minutes with the standing and light walking breaks lasting between 2 to 5 minutes, Buffey said.
Standing was better than heading straight for the desk or the couch to sit when it came to blood sugar levels, but it didnt help lower insulin in the bloodstream, the analysis found.
However, if people went for a short walk after eating, their blood sugar levels rose and fell more gradually, and their insulin levels were more stable than either standing or sitting, the study noted.

Why Your Blood Sugar Level May Be Low
If blood sugar drops below 70 mg/dL, it is below normal levels. This can be caused by a variety of factors, such as:
- Not eating enough or missing a meal or snack
- Reducing the amount of carbohydrates you normally eat
- Alcohol consumption especially if youre drinking on an empty stomach
- Taking too much insulin or oral diabetes medication based on carbohydrates or activity levels
- Increased physical activity
- Side effects from medications
If you have diabetes, keep your blood glucose meter and sources of fast-acting glucose close by in case your blood sugar drops. This is especially important for people with hypoglycemia unawareness, which is a condition that causes symptoms of low blood sugar to go unnoticed.
Eating balanced meals and snacks at regular times throughout the day is a big part of maintaining normal blood glucose levels. Check out our article on meal planning for diabetes to better understand the three macronutrients where calories come from and which have the biggest effect on blood sugar.

Everyone will respond differently to certain factors, which is why its important to have individualized target glucose levels. To help you reach your target blood glucose goals, work with your healthcare provider to discuss modifications to your diet, physical activity, or medications, and alert them of other factors like a recent illness or stressful event.
Normal Range For Blood Sugar Two Hours After Eating
Your blood glucose levels can determine whether you have or are at risk for developing diabetes, a condition in which your body no longer effectively processes and absorbs glucose from the bloodstream. Blood glucose levels fluctuate during the day, particularly after meals. Postprandial — which means after eating — glucose levels that rise beyond a certain level may mean you have diabetes or prediabetes. However, two-hour postprandial blood sugar testing is not recommended to screen for or diagnose diabetes.

Tips For Avoiding High And Low Blood Sugars
Walking the tightrope of a life with diabetes is not easy.
We need to strive every day to make sure that we dont let our blood sugars go too high or too low, and that can be exhausting.
Here are some strategies to help keep your blood sugar in balance:
- Eat similar foods and meals that have predictable carbohydrate counts
- Cook food at home, so you know all of the ingredients in your meal
- Keep to a routine, and eat at the same times every day
- Get enough sleep!
- Double-check your insulin doses to make sure youre not taking too much, nor too little
- If youve counted carbohydrates for a meal and dosed insulin for those carbohydrates, eat everything
Several Factors May Cause A Persons Postprandial Blood Sugar To Remain Elevated
Smoking after the meal: Studies show that smoking raises blood sugar levels in people with diabetes. Extreme stress: Stress produces the bodys fight-or-flight response triggering the release of stress hormones such as cortisol. These hormones cause the body to release the glucose it has previously stored for energy. Eating or drinking after the meal and before testing the blood sugar: Continuing to eat will keep blood sugars closer to their immediate post-meal levels.
Studies show that 15 to 20 minutes of moderate exercise, such as walking, shortly after a meal may improve glucose metabolism and reduce postprandial glucose levels.

High Calorie Foods May Or May Not Cause The Blood Sugar Level To Rise
Many people think that all high-calorie foods raise blood sugar level, but this is not always the case.
In general, foods that cause blood sugar level to rise the most are those that are high in carbohydrates, which are quickly converted into energy, such as rice, bread, fruits and sugar. Next are foods high in protein, such as meats, fish eggs, milk and dairy products, and oily foods. However, even though carbohydrates affect blood sugar levels, if you don’t eat them your diet will be unbalanced and you won’t feel satisfied after your meal, which can lead to excessive consumption of foods rich in protein and fat.

Hba1c Test For Diabetes Diagnosis
An HbA1c test does not directly measure the level of blood glucose, however, the result of the test is influenced by how high or low your blood glucose levels have tended to be over a period of 2 to 3 months.
Indications of diabetes or prediabetes are given under the following conditions:
- Normal: Below 42 mmol/mol
- Prediabetes: 42 to 47 mmol/mol
- Diabetes: 48 mmol/mol
What Happens If My Blood Glucose Level Becomes Too Low
Sometimes blood glucose levels drop below where they should be, which is called hypoglycemia. For most people with diabetes, the blood glucose level is too low when it is below 70 mg/dL.
Hypoglycemia can be life threatening and needs to be treated right away. Learn more about how to recognize and treat hypoglycemia.

What Causes Your Blood Glucose To Go Up
Blood glucose refers to the amount of glucose that is circulating through your blood, ideally headed to cells for energy. Insulin is the hormone that allows glucose into our cells, but those with type 1 diabetes don’t produce insulin and those with type 2 diabetes are resistant to insulin and don’t use it effectively.
Things that can make our blood glucose levels go up include food, stress and illness. Things can can cause our blood glucose levels to go down can include long periods of time without eating, taking too much medication and physical activity.
Each person, regardless of whether they have diabetes, has their own healthy blood sugar target range where their body functions as its best. If you have diabetes, it’s important to identify what your range is, and how it compares to a range that would make you feel your best. Talk with your healthcare team about your current range as well as what the healthiest range for you would be.
Why Does Blood Glucose Level Rise In Diabetes
The food we eat is converted to glucose and released into the bloodstream. Therefore, blood sugar levels are high after eating. The increase in glucose level signals our pancreas to release insulin.
Insulin helps our body cells to absorb glucose. As a result, blood glucose level goes down / becomes normal again. This process of cell absorption helps in regulating/maintaining normal blood glucose levels.
But in the case of diabetes, our body becomes insulin resistant, or there is insulin deficiency. Due to this our body cells do not absorb blood glucose, resulting in high blood glucose levels, thus causing Diabetes which comes with health problems like thyroid, stress, loss of muscle weight, acidity, insomnia, low energy level, etc. Over a period of time, such high blood glucose levels can cause damage to nerves, kidneys, eyes, and heart. With the right changes in your habits of eating, exercising, sleeping patterns, and stress management we have seen more than 10.000 patients reversing their diabetes. Get started with your diabetes reversal journey, connect with top diabetes experts now.

The Importance Of Maintaining Good Blood Sugar Levels
You must look after the blood glucose levels to ensure that it is in control. Not maintaining good blood sugar levels may prove risky for your health and might result in an increased risk of diabetes complications.

What Are Normal Blood Sugar Levels In Healthy Individuals
Blood sugar levels can either be normal, high, or low, depending on how much glucose someone has in their bloodstream. Glucose is a simple sugar thats present in the bloodstream at all times. Blood glucose levels can be measured at any time, for example, when someone fasts , before they eat, or after theyve eaten. A normal blood glucose level for adults, without diabetes, who havent eaten for at least eight hours is less than 100 mg/dL. A normal blood glucose level for adults, without diabetes, two hours after eating, is 90 to 110 mg/dL.
Many factors affect blood sugar levels throughout the day:
- Type of food consumed, how much, and when
- Physical activity
- Menstrual periods
An ideal blood sugar level for anyone without diabetes or prediabetes, regardless of age, in the morning should be less than 100 mg/dL. Remember, blood sugar levels can fluctuate throughout the day as a result of the factors previously mentioned.
Target Glucose Ranges For Adults
- Fasting glucose range: 72-90 mg/dL or 4.0-5.0 mmol/L
- Before eating: Depends on what you ate, what you did, and what you plan to eat
- Glucose range 1-2 hours after eating: < 120 mg/dL or 6.7 mmol/L
Most blood sugar charts show recommended levels as a range, allowing for differences between individuals. People with diabetes will often have higher blood sugar targets or Ã¢acceptableÃ¢ ranges than those without the condition, although a standard treatment goal in diabetes is to keep your blood glucose in a normal range as much as possible.
For type 1 diabetics and type 2 diabetics, blood sugar ranges are higher than the averages and targets listed above. According to the American Diabetes Association, average blood sugar levels for diabetics are:
- Fasting plasma glucose: 126 mg/dL or higher
- Before eating: 80Ã¢130 mg/dL
- One to two hours after eating: < 180 mg/dL
Diabetes occurs when the pancreas cannot make enough insulin to clear glucose out of the blood. Insulin is a hormone made by the pancreas that moves glucose from what we consume from the bloodstream and into the cells to make energy.
Abnormal blood sugar occurs when thereÃ¢s either too much or too little sugar in the blood.
