What are Blood Glucose levels?

Glucose Levels (1)

The blood glucose level is the amount of glucose in the blood. Around 4 grams of glucose is present in the body of around 70kgs all the time. Blood Glucose levels generally rise after you eat food. It later falls after a few hours when insulin moves glucose in your cells. 

What is Blood Glucose? 

Blood Glucose or Blood Sugar is the main sugar found in the blood. Glucose is an amount of sugar that comes from the food we consume, carried through the bloodstream to provide energy to the cells in the body. It forms and stores inside your body.

Glucose comes mainly from foods that are rich in carbohydrates like potatoes, bread, fruit, etc. As you eat the food travels down from your food pipe to your stomach. There,  body acids break it down into tiny pieces during which glucose is released. It then goes into your intestine where it gets absorbed from where it passes into the bloodstream. After which insulin secreted from the pancreas, helps glucose to get into your body cells.

Normal Glucose Level ChartChildren’s Glucose Levels

Children under 6 should have glucose levels that are between 80 to 200 mg/dL. This is an appropriate range and is considered healthy and the amount of glucose in a child’s body will now differ from the time they wake up, have food, and before bedtime. For eg. Before a meal, the average blood sugar level ranges from 100-180 mg/dL , a few hours after eating it is approximately 180 mg/dL and at the end of the day (bedtime) it ranges from 110-200 mg/dL. Sometimes kids with diabetes or in hypoglycemia cases, children may have to get tested by their parents in the middle of the night.

For eg. in the early morning, it may range between 80 to 180 mg/dL, a before meal approximately 90 to 180 mg/ dL. Blood sugar levels may go up after eating food because the body breaks down the carbs into glucose, which gets distributed in the bloodstream like after a few hours it can range up to  140 mg/dL, and at the time of the sleep (bedtime), it ranges from 100-180 mg/dL.
