Normal Fasting Blood Sugar For Person Without Diabetes
A normal fasting blood glucose for someone who does not have diabetes ranges from 70 to 99 mg/dl. The American Diabetes Association recommends a routine screening for type 2 diabetes starting at age 35. If the results are normal, the screening should be repeated every three years.
If have diabetes risk factors, which include being overweight or obese, having a family history of type 2 diabetes, having a history of gestational diabetes, or being of a certain race/ethnicity , you should be screened for diabetes sooner and repeat testing may be recommended more often.
Children and adolescents who have diabetes symptoms or who are overweight and have a family history of type 2 diabetes, are of African American, Latino, Asian American, Native American or Pacific Islander descent, who have signs of prediabetes or a mother who had gestational diabetes should be tested beginning at age 10 or the onset of puberty and then every three years thereafter.
A fasting blood sugar of 100 to 125 mg/dl is indicative of prediabetes, which is a condition where blood sugar levels are above normal but not high enough to be considered diabetes. Prediabetes is a risk factor for type 2 diabetes, heart disease and stroke. Its managed by lifestyle changes and, in some cases, medication.
How Does Blood Sugar Level Work
With a lack of nutrients and food that contain glucose, the blood sugar level will begin to decline. This is known as hypoglycemia.
After blood sugar becomes low, the pancreas releases a peptide hormone called glucagon. When this happens, the glucose that is stored in the body for energy is instructed to release due to the liver. This causes the glucose to turn into glycogen, known as the glycogenesis process. This is what can help a body to regain energy as the readily stored glycogen, in the liver and muscles, will release into the body.
On the other hand, the blood sugar can also rise and become too high which is known as hyperglycemia.
When the body does not produce enough of the insulin hormone, blood sugar levels begin to increase. This is because glucose relies on the insulin hormone to help it absorb into the bloodstream. Usually, this occurs when the body cannot produce enough insulin, known as type 1 diabetes, or does not respond to insulin correctly, known as type 2 diabetes.
Eating too many processed foods can also cause your blood sugar level to rise. If there is not enough insulin present in the body, too much bad food can cause your blood sugar level to build up.
For those with a normal blood sugar level, this will be due to eating the right foods and your body being able to produce and respond to insulin.
You may be wondering what exactly causes an imbalance in blood sugar levels, so here is a roundup:

Blood sugar levels exceeding 126 mg/dL in the morning indicate hyperglycemia. If you take the blood sugar reading on an empty stomach in the morning, and it still shows you glucose levels exceeding the 126 mg/dL mark, it highlights hyperglycemia. You should report it to your doctor and start timely treatment.

Target Blood Sugar Ranges For Pregnant People With Diabetes
Blood sugar targets during pregnancy are lower due to hormonal influences. The ADA, AACE, and Joslin Diabetes Center have slightly different guidelines for target blood sugar levels during pregnancy. In general, pregnant women with diabetes will want to follow individual guidelines provided by their endocrinologist.
The ADA recommends maintaining blood sugar levels of 95-140 mg/dL for pregnant women. However, some providers recommend an even tighter goal of blood glucose levels below 89 mg/dL before a meal and below 120 mg/dL after a meal.
To keep close tabs on levels, most diabetes specialists recommend that women with diabetes during pregnancy check their blood sugar:
- First thing in the morning
- Before all meals
The Danger Of Low Blood Sugar
Low blood sugar, also known as hypoglycemia, can become a lot more dangerous more quickly. Hypoglycemia, if left untreated, can quickly result in diabetic coma and death.
Low blood sugars will not lead to permanent complications in most cases but cause frequent, short-term complications in the form of being physically unable to function when experiencing a low. They require fast-acting glucose as treatment.
Symptoms of low blood sugar can hit different people at different times, and some people may not feel their low blood sugars at all , which can be very dangerous.
Continuous glucose monitoring systems and diabetes alert dogs can help people detect their lows earlier, before they become extremely dangerous.
Hypo unawareness occurs in about 40% of people with type 1 diabetes, and less frequently in people with type 2 diabetes.
Additionally, one study showed that the average person with type 1 diabetes experiences two episodes of low blood sugar per week!
Low blood sugars can happen for many reasons, all of which result from too much insulin in the bloodstream and not enough glucose for the body to function properly.
Reasons can be anything from taking too much insulin for food, to accidentally over-bolusing with an insulin pump, to not finishing a meal, to drinking alcohol in excess, or even after physical exertion and exercise while not reducing basal insulin settings appropriately.

The Danger Of High Blood Sugar
Having a high blood sugar means there is too much sugar in the blood because the body is lacking in insulin. This can happen for many reasons, including not taking enough insulin exogenously, too little exercise, eating too much, or even stress, hormonal changes, or lack of sleep.
High blood sugar is dangerous, but its important to remember that high blood sugar is mostly dangerous over prolonged periods of time .
This means that, for the most part, your blood sugar at diagnosis will not cause long-term complications, and the spike you saw last week from eating an ice cream sundae wont impact you over the long term.
But chronic, prolonged high blood sugars will cause diabetes complications in most people.
What Are The Complications Of Low Blood Glucose
Mild-to-moderate low blood glucose can be easily treated. But severely low blood glucose can cause serious complications, including passing out, coma, or death.
Repeated episodes of low blood glucose can lead to
- high blood glucose levels, if worry or fear of low blood glucose keeps you from taking the medicines you need to manage your diabetes8
- hypoglycemia unawareness, a condition in which you dont notice any symptoms of low blood glucose until your blood glucose level has dropped very low
How Soon After Waking Up Should You Test My Blood Sugar
Since people can now check their blood sugar levels at home, doctors generally recommend fasting blood sugar test almost immediately after waking up. An empty stomach is generally the best time to test blood sugar in the morning. You should get the reading done when you havent had breakfast or any morning drink.
What Is A Blood Glucose Test
A blood glucose test is a blood test that mainly screens for diabetes by measuring the level of glucose in your blood.
There are two main types of blood glucose tests:
- Capillary blood glucose test: A healthcare professional collects a drop of blood usually from a fingertip prick. These tests involve a test strip and glucose meter , which show your blood sugar level within seconds.
- Venous blood glucose test: A phlebotomist collects a sample of blood from a vein . These glucose tests are usually part of a blood panel, such as a basic metabolic panel. The provider will send the samples to a lab. There, a medical laboratory scientist will prepare your samples and perform the test on machines known as analyzers.
Venous blood glucose tests are generally more accurate than capillary blood glucose tests.
Healthcare providers often order fasting blood glucose tests to screen for diabetes. Since eating food affects blood sugar, fasting blood glucose tests show a more accurate picture of your baseline blood sugar.
Theres also at-home blood sugar testing for people who have diabetes. People with Type 1 diabetes especially need to monitor their blood sugar multiple times a day to effectively manage the condition. Continuous glucose monitoring devices are another option for this.

What Is A Rather Good Blood Sugar Level In The Morning
If youre planning to take your blood sugar readings in the morning before breakfast, it should be around 70 mg/dL to 100 mg/dL. This range is considered normal and is often reported by non-diabetic people. But if you take the glucose reading after breakfast, the readings can spike. Even in the morning, the normal diabetes level should not exceed 140 mg/dL. If it does, talk to your doctor.
Blood Sugar Level Charts For Those With Diabetes
Normal blood sugar levels, for those with diabetes, will vary depending on someones age and the time of day. For example, when fasting, blood sugar levels are often in the target goal range. The type of food eaten will impact blood sugar levels in different ways. A meal with a lot of carbohydrates will raise blood sugar quicker than a meal that contains carbohydrates, protein, and fat . Blood sugar will rise after a meal, but will start to return to normal levels in several hours.
Lets take a look at what blood sugar levels should be, in those with diabetes, based on their age.

Normal And Diabetic Blood Sugar Ranges
For the majority of healthy individuals, normal blood sugar levels are as follows:
- Between 4.0 to 5.4 mmol/L when fasting
- Up to 7.8 mmol/L 2 hours after eating
For people with diabetes, blood sugar level targets are as follows:
- Before meals : 4 to 7 mmol/L for people with type 1 or type 2 diabetes
- After meals : under 9 mmol/L for people with type 1 diabetes and under 8.5mmol/L for people with type 2 diabetes
Official Fasting Blood Sugar Ada Recommendation For Someone With Diabetes
The American Diabetes Association recommends a fasting blood sugar target of 80 to 130 mg/dl for most nonpregnant adults with diabetes. However, the fasting blood sugar target may need to be individualized for certain people based on such factors as duration of diabetes, age and life expectancy, cognitive status, other health conditions, cardiovascular complications, and hypoglycemia unawareness. Its important that people with diabetes discuss their target blood sugar goals with their health care provider.
Are Low Blood Sugar Levels Dangerous
Your bodys cells require energy to function. Sugar is the bodys primary energy source, commonly known as glucose.
Hypoglycemia is the medical term for when your blood sugar levels drop below the usual range. Low blood sugar can cause various symptoms, but a blood glucose test is the only method to diagnose low blood sugar.
One of the most common causes of low blood sugar is medications for treating diabetes. The pancreas can no longer make insulin when a person has type 1 diabetes. In type 2 diabetes, the pancreas produces insufficient insulin, or your body has trouble utilising it. Hypoglycemia can occur due to excessive amounts of insulin or oral diabetic medication to reduce blood sugar levels and control both types of diabetes.
Contrary to popular assumption, low blood sugar is not only a symptom associated with diabetes but it may occur even when your body produces more insulin than what is considered healthy. Consuming excessive amounts of alcohol, especially over extended periods, is another potential factor in low blood sugar. The livers capacity to store glucose and release it into your bloodstream when needed may be hampered by this.
Your cells become energy-starved when your blood sugar levels are too low. Initial signs may include minor ones like hunger and headaches. However, you could face significant risks if you dont raise your blood sugar levels promptly.
Normal Hba1c For Person Without Diabetes
For someone who does not have diabetes, a normal HbA1C level is below 5.7%. An A1C between 5.7% to 6.4% is indicative of prediabetes.
Its recommended that adults over the age of 45 or adults under 45 who are overweight and have one or more risk factors for diabetes have a baseline A1C checked. If the result is normal, the A1C should be checked every three years. If the result indicates prediabetes, the A1C should be checked every one to two years.

What Level Of Blood Sugar Is Dangerous
Diabetes is a long-term illness that affects how your body converts food into energy. Your body converts most of the food you consume into sugar , which then releases into your bloodstream. Your pancreas releases insulin when your blood sugar levels rise.
Insulin is essential for enabling blood sugar to enter your bodys cells to provide them with energy. Unfortunately, when you have diabetes, your body produces insufficient insulin or uses it improperly.
As a result, too much blood sugar remains in your bloodstream due to low insulin or cells themselves cease reacting to insulin. This can eventually lead to significant health issues like renal disease, eyesight loss, and heart disease.
Blood Sugar Level Chart By Age
Blood sugar levels tend to rise with age due to an increase in insulin resistance and decrease in insulin sensitivity. In one study by the National Health Institute , each extra decade of age was linked to a 2.7 mg/dl increase in fasting glucose, and a 4.5 mg/dl increase in 2-hour post-prandial glucose levels.

- Keep track of your blood sugar levels to see what makes them go up or down.
- Eat at regular times, and dont skip meals.
- Choose foods lower in calories, saturated fat, trans fat, sugar, and salt.
- Track your food, drink, and physical activity.
- Drink water instead of juice or soda.

- Control your food portions .
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

The important thing to remember is to take action as quickly as you can, to stay with it, and to stay on top of your condition. Its treatable. Its manageable. And its a fight that you can win.
Improving Fasting Blood Sugar Levels
If a person does not have perfect fasting blood sugar levels, yet the levels are not quite high enough to be considered diabetes, they should take it as an opportunity to improve their health and achieve average blood glucose levels prior to developing type 2 diabetes. Usually, high blood sugar levels have to do with a poor diet, but even more often they have to do with a personâs lack of exercise and physical activity.
A number of medical studies have shown a dramatic relationship between elevated blood sugar levels and insulin resistance in people who are not very active on a daily or regular basis. Many of the same studies have also shown that the most efficient way of improving insulin resistance is to increase the amount of physical activity. Doing so helps a person to achieve weight loss, increase blood flow and circulation, as well as lower blood sugar levels.

Complications From Chronic High Blood Sugar
Over time, high blood sugar damages the arteries and vessels of the body. When these vessels are damaged, complications can occur.
- Heart disease: people with diabetes are two to four times more likely to die from cardiovascular disease than those without diabetes. People with diabetes are also more likely to have high blood pressure, which is another risk factor for heart disease.
- Stroke: Diabetes increases the risk of stroke, as well as increases mortality when a stroke occurs.
- Kidney disease and failure: High blood sugar damages the kidneys and can lead to kidney disease. About one in four people with diabetes have kidney disease.
- Poor wound healing leading to amputations: High blood sugar inhibits proper wound healing. Diabetes is thought to be the leading cause of leg amputations worldwide.
- Neuropathy: Damage to the nerves, which can cause painful symptoms like numb and tingling legs and feet, as well as delayed stomach emptying from damage to the stomachs nerves.
- Retinopathy and blindness: Damage to the nerves in the eyes is called retinopathy, which can lead to blindness if not treated.
