Health

 Blood sugar refers to the amount of glucose present in the blood of humans and animals and is the primary source of energy for body cells and blood lipids. Maintaining appropriate blood sugar levels is crucial for overall health.

 

Normal Blood Glucose Levels

 

Normal blood glucose levels typically range between 70 and 100 mg/dL when fasting. For individuals with type 1 diabetes, typical target ranges are 4.4 – 7.2 mmol/L (80 – 130 mg/dL) before meals and under 10.0 mmol/L (180 mg/dL) after meals. These targets can vary based on individual health needs, so it's important to consult with a healthcare team to establish personalized goals.

 

High Blood Sugar (Hyperglycemia)

 

Hyperglycemia occurs when blood glucose levels are too high. This can result from insufficient insulin secretion or inefficient insulin use by the body.

Common symptoms of hyperglycemia include:

 

- Thirstiness

- Increased hunger

- Frequent urination

- Headache

- Blurred vision

 

Long-term hyperglycemia can lead to complications such as diabetic ketoacidosis, cardiovascular disease, nerve damage, kidney damage, and vision problems.
