Blood Sugar Level During Fasting


Blood Sugar Level Fasting

What is the Blood Sugar Level?

The Blood Sugar or Blood glucose is the sugar or glucose content found in the blood. It is found in animals and humans. The body requires glucose which comes from the food we eat. This glucose is the main source of energy to supply nutrients to organs, muscles and various parts of the body. However, the body does not use all the insulin at once. Insulin makes it to store and release when necessary. This is usually found in people who lack insulin and is become one of the most common diseases.

After a meal, the blood sugar levels rise to peak about an hour after eating.
Diabetes is of two types: Diabetes 1 and Diabetes 2. 

Diabetes 1: A condition where the pancreas does not produce insulin and hormone which is required by the body to maintain blood sugar level in our body.


Diabetes 2: A condition in which the body is resistant to insulin and in some cases pancreas that slows or stops producing insulin

What are the different levels of Blood Sugar?

 Normal blood sugar level:

The normal ranges for blood sugar in adults who do not have diabetes before eating or fasting begins at 72-99mg/dL and while fasting range from 80—130 mg/dL and less than 180 mg/dL after 2 hours of the meal.

High blood sugar level (Hyperglycemia):

High blood sugar is found in people already suffering from diabetes.  The level ranges more than 130mg/dL before a meal and more than 180mg/dL after the meal.

Low blood sugar level (Hypoglycemia):

The low blood sugar is a condition that occurs when the blood glucose level drops down below normal that is when the level is below 70mg/dL before the meal.
The below image displays the structure of different levels of blood sugar:

Fasting blood sugar level:
A fasting blood sugar level less than 100 mg/dL is considered to be normal. If the blood sugar level is from 100-125 mg/dL a person is prediabetes. This test must be done on an empty stomach without consuming water and food.

The fasting blood sugar depending on three main factors: 

Contents of last meal
Size of previous meal
The body’s ability to produce and respond to insulin

Testing of Blood Sugar

There are two methods that a person or any healthcare sectors would use to assess fasting blood sugar levels:

Testing blood sugar at home

A person can test their blood sugar level at home. Some doctors ask people to check the sugar level immediately after waking and two hours after the meal.  
Fasting (morning testing before food and water): 80-130 mg/dL and two hours after food under 180 mg/dL.

To do blood sugar level testing at home, a person will have to:

  • Preparing the testing strip and glucose monitor must be ready for blood sample
  • Clean the testing area using an alcohol swab
  • Squeeze the testing area (finger) around the wound to maximize blood flow
  • Squeeze a drop of blood on the testing strip
  • Put the strip into the monitor
  • Record the time, reading and food intake in a log


This test checks the sugar level for over 2-3 months. This test is performed in labs. It is not required for a person to fast before undergoing the test. The result is reported in terms as a percentage, the higher the percentage, the higher is the blood sugar level. HbA1c test


How can a person keep the Blood Sugar in control?

We can keep our Blood Sugar in control using the following methods:


  • Healthy weight: Having an ideal weight and being healthy and fit.
  • Healthy Diet: Consumption of wholesome, unprocessed food, fruits and vegetables. Foods that contain a lot of carbohydrates eg cookies digest quickly but spike the insulin levels in the pancreas.
  • Physical Exercise: At least 30 minutes of brisk walk reduces the sugar levels.
  • Get insulin checked in accurate intervals: Checking the insulin levels and taking precautions accordingly.
  • Limited intake of salt and sugar
  • Replace pasta or Maida items with wheat
  • Eat foods that are high in fiber which helps in control blood sugar levels
  • Proactive steps to be taken for people who are under diabetes drugs and prevent blood sugar from dropping:
  • Regular meals throughout the day
  • Increase food intake and snacking frequency during physical exercise
  • Avoid alcoholic beverages
