Blood glucose levels without food: what is normal?

  Articles

When a person has diabetes, blood glucose levels can rise above normal or fall below normal.

If a person has type 1 diabetes , they are not producing insulin as they should. If a person has type 2 diabetes , it means that they do not respond adequately to insulin. This is a problem because insulin is a hormone that moves glucose into the cells of the body. It is necessary for energy and health.

What is blood glucose?

Glucose in the blood comes from food. When a person eats, the food is broken down into sugar and released into the bloodstream. Insulin helps sugar get into cells. Once this happens, the sugar that has moved from the blood into the cells is used for energy or stored.

Glucose is known as the body's main source of energy. Too much glucose in the blood or not being absorbed properly can cause health problems in both the long and short term. To maintain normal blood sugar levels, it is important to:

  • Eat healthy food
  • Exercise regularly
  • Check your blood glucose
  • Stay in touch with your doctor.

To maintain normal blood sugar levels, it is important to stay in contact with a healthcare professional, eat healthy, monitor your blood glucose levels, and exercise regularly.

Fasting vs non-fasting blood sugar

Fasting blood sugar is a test that measures blood sugar and is used to determine if a person has diabetes. When a person has this test, they should not eat or drink for at least eight hours before the test. The results determine whether a person is prediabetic or diabetic.

Results are measured in milligrams per deciliter or mg / dl. The following results indicate whether a person is prediabetic or diabetic:

  • Norm: less than 100 mg / dl
  • Prediabetes: 100 mg / dL to 125 mg / dL
  • Diabetes: 126 mg / dL or more

To check blood sugar without food, the A1C test is done to determine a person's average blood sugar level over a period of two to three months. It is not necessary to fast before doing this test. The following results indicate whether a person is prediabetic or diabetic:

  • Normal: 5.7%
  • Prediabetes: 5.7 to 6.4%
  • Diabetes: 6.5%

Normal blood sugar

It is important to work with your healthcare provider to maintain healthy blood sugar levels. Below is a list of normal blood sugar levels.

If the person has type 1 diabetes, the blood sugar level should be as follows:

  • Before meals: 90 to 130 mg / dL (5.0 to 7.2 mmol / L) for adults.
  • After meals (1-2 hours after meals): less than 180 mg / dL (10 mmol / L) for adults.
  • Before bedtime: 90 to 150 mg / dL (5.0 to 8.3 mmol / L) for adults.

If the person has type 2 diabetes, the levels should be as follows:

  • Before meals: 70 to 130 mg / dL (3.9 to 7.2 mmol / L) for adults.
  • After meals (1-2 hours after meals): less than 180 mg / dL (10.0 mmol / L) for adults.

Blood sugar levels in children and babies.

Normal blood glucose levels in children include:

  • 0 to 5 years: 100 to 180 mg / dL
  • 6 to 9 years: 80 to 140 mg / dL
  • 10 years and older: 70 to 120 mg / dL

Hypoglycemia

Hypoglycemia is a glucose level below 70 mg / dL. If there is not enough glucose in the body, this can lead to symptoms such as:

  • Dizziness
  • Instability
  • Difficulty speaking
  • Fast breathing
  • Hunger
  • Nausea
  • Feeling anxious or weak

If a person has diabetes, hypoglycemia can sometimes be a side effect of diabetes treatment.

If a person has hypoglycemia and glucose levels that are too low, it can lead to a diabetic coma . If the person is unconscious, it is important to call 911 immediately. Anyone with diabetes should always keep in touch with their healthcare provider with any questions or concerns.

When to seek emergency help

If your blood sugar level drops below 70 mg / dL or you feel tired or dizzy, call 911.

Hyperglycemia

Hyperglycemia is high blood sugar. This happens when there is not enough insulin in the body and there is too much sugar in the blood.

Some of the symptoms of hyperglycemia include:

  • High blood sugar level
  • Blurry vision
  • Headache
  • Fatigue
  • Frequent urination
  • Increased hunger and / or thirst.

If hyperglycemia is not treated properly, it can lead to both long-term and short-term health problems. If the blood sugar level is too high and is not treated, the patient can fall into a diabetic coma .

Generalized hyperglycemia can be maintained and / or prevented by:

  • Eat properly
  • Training
  • keep a healthy weight
  • Take medications as directed
  • Stop smoking and drinking alcohol

It is important to work with your healthcare provider to get the best possible outcome for this condition.

Ketoacidosis

If a person has type 1 diabetes and their hyperglycemia is not treated, they have the potential to develop into diabetic ketoacidosis (DKA) . This is where toxic acids or ketones build up in the blood. It is an extremely serious condition that can cause coma or death.

Get the word of drug information

Diabetes can create many health complications if it is not treated properly. It is very important to check your blood sugar level regularly. If diabetes is not treated, it can have dangerous consequences.

It is important to stay in contact with your doctor and follow his plan for your health, medications, and lifestyle.
