Calculate Blood Sugar Level.
The major sugar present in blood is called blood sugar, or glucose. It provides energy to muscles, organs, and the nervous system. The small intestine, liver, and pancreas regulate glucose absorption and storage.
After eating, glucose floods the bloodstream. The pancreas releases insulin, which stores excess glucose as glycogen in the liver. When needed, the liver converts glycogen back to glucose through a process called glycogenolysis.
Fasting Blood Sugar: Less than 100 mg/dL.
Post-Meal: Less than 140 mg/dL (2 hours after eating).
Before meals, levels usually range between 70–90 mg/dL. Extended fasting may not drop levels below 60 mg/dL for most individuals.
Glucose mainly comes from carbohydrate-rich foods like bread, fruits, and potatoes. During digestion, enzymes break food into glucose, which is absorbed into the bloodstream through the intestines. Insulin helps transport glucose to cells for energy.
Blood sugar levels indicate the glucose concentration in your body. These levels fluctuate throughout the day, especially after meals. In diabetes, these variations are more pronounced, requiring regular monitoring to manage the condition and prevent complications like nerve damage or vision loss.
After eating, blood sugar rises, then falls as insulin transports glucose into cells. In diabetes:
When unmanaged, blood sugar levels remain high, leading to complications.
Blood sugar levels are calculated using various methods:
