All About Blood Sugar Levels – High, Low, and Normal

Diabetes is a lifestyle disease in which the body has an impaired ability to produce and respond to the hormone insulin. Patients can suffer from any Type 1 diabetes or Type 2 Diabetes. Read this blog to know about blood sugar level in detail.

The pancreas stops making insulin in Type 1 diabetes and patients with Type-2 Diabetes have cells that are resistant to insulin or the pancreas slows down its function and stalls the production of adequate insulin levels (blood glucose).

Both types of diabetes can lead to abnormal glucose levels. The amount of glucose present in the blood in someone’s body at any given time can be defined as blood glucose levels. If these levels are too high or too low, it could indicate an underlying health condition that may require immediate medical help.

The blood sugar levels can be normal, high, or low, depending on how much glucose someone has in the blood. Normal levels can be measured when someone fasts or after they’ve eaten.

Normal blood glucose level in adults without diabetes, who have been fasting for eight hours should be less than 1000 mg//dL. Similarly, if a blood glucose level ranges between 90 to 110 mg/dL in adults after two hours of eating, then it is said to be normal.

Adults should have blood sugar levels that range between 100 to 180 mg/dL in a day. Fasting blood sugar level should be at its lowest because you have not been consumed food for over seven hours. 

The normal blood sugar level for diabetics should be less than 140 mg/dL (7.8 mmol/L). If the report level comes between 140 to 199 mg/dL (7.8 mmol/L and 11.0 mmol/L) then the patient is said to be diagnosed as prediabetes. If a diabetes patient is testing after two hours of eating then it should range 200 mg/dL (11.1 mmol/L) or higher. 

There are many factors that affect blood sugar levels throughout the day. It includes physical activity, medical condition, age, stress, type of food consumed, dehydration, alcohol, menstrual periods, etc. 

1. What is the normal range for blood glucose levels in Australia?

For the people living in Australia, normal blood glucose levels range between 4.0–7.8 mmol/L.

2. What are normal blood sugar levels in the UK?

The normal blood sugar levels for people, without diabetes, living in the UK should range between 4 and 6 `mmol/L before meals i.e. less than 8 mmol/L two hours after consuming.

Instrument used for testing glucose levels in the UK is ‘mmol/L’ and mg/dL is used in the USA and continental Europe. 

In people without diabetes, the blood glucose varies from 4 mmol/L to 6 mmol/L.

Fasting Blood Sugar Test (FBS)

This test tells the value of blood glucose at a specific time. To get an accurate result, it is advised to get a blood test done in the morning without eating anything except water for 8-10 hours. If the fasting blood sugar is 120mg/dl or more, it is termed diabetes. 

Post-Prandial Blood Sugar (PPBS)

A postprandial blood sugar test also known as PPBS should be done two hours after eating. If blood sugar values more than 200mg/dl indicates that a patient has diabetes mellitus.

Random Blood Sugar Test (RBS)

A person can get a random blood sugar sample tested any time in a day. It is very useful for suspecting diabetes.  If the result is more than 160- 200 mg/dl, then the patient is suffering from diabetes.
