What is Blood Sugar Level?


Our bodies contain some amount of sugar in the blood as well as body cells at all times. This sugar is the fuel for all body functions. The blood sugar level, also known as blood glucose level in the body is maintained by the hormones insulin and glucagon.

In normal circumstances, a random blood glucose level is less than 140 mg/dL. However, there can be a change in the blood sugar level when there is impaired insulin production, or the hormone is unable to control the sugar level in blood. This condition is called Diabetes Mellitus.


What is Blood Sugar Range?


There is a blood sugar range that your body functions best between, and any variation above or below this can have detrimental effects. For this reason, it is essential to get your blood sugar range checked once a year (if you are not a diabetic) and every three months if you are a diabetic.

The sugar level in the human body varies as per the physiologic state of the body and is usually lowest just before a meal or when you have fasted for a minimum of 8 hours. This level rises and peaks at about 2 hours post-meal.

The normal sugar range is different for different people, and 60-100mg/dL is an acceptable average sugar level. Anything above or below this range is a cause for concern.

What are Normal Blood Sugar Levels?


The normal blood sugar level is less than 100mg/dL fasting (when you haven’t eaten for 8 hours) and less than 140mg/dL two hours after eating. The normal sugar level is usually found to be the lowest just before meals during the day.


What is Low Blood Sugar Level (Hypoglycemia)?


Though possible, there are fewer chances that your body will have low blood sugar or its level falling below 60mg/dL as your liver keeps on converting  stored fat into sugar to keep the blood sugar level at an optimum level.

Hypoglycemia means having low blood sugar levels (below 60mg/dL) and can actually be a dangerous condition. This is common in diabetics when they take excess medication, skip meals or workout more than required.


What is High Blood Sugar (Hyperglycemia)?


Having high blood sugar levels is dangerous and is the characteristic sign of diabetes mellitus. This condition is called hyperglycemia. Clinically, hyperglycemia means having fasting blood sugar levels higher than 126 mg/dL and post-prandial (2 hours after a meal) blood sugar levels of more than 200 mg/dL.

In most cases, you will not experience the signs and symptoms of diabetes until you observe dangerous blood sugar levels of over 250mg/dL. The classic sign of chronic high blood sugar levels is polyuria (excessive urination), polydipsia (excess thirst) and polyphagia (excess hunger).
