Healthy blood sugar levels refer to the amount of glucose present in your bloodstream, which is regulated by the hormone insulin. Glucose is a primary source of energy for your body’s cells, and it comes from the foods you eat.
A healthy blood sugar level is generally considered to be between 70-99 mg/dL (milligrams per deciliter) when measured after an overnight fast. After meals, blood sugar levels may briefly rise, but should not exceed 140 mg/dL. These levels can vary depending on factors such as age, weight, physical activity, and overall health.
When blood sugar levels are consistently above the healthy range, it can lead to a condition called hyperglycemia. This can be a sign of pre-diabetes or diabetes, a chronic condition in which the body is unable to regulate blood sugar levels effectively. Over time, high blood sugar levels can cause damage to the blood vessels and nerves, leading to serious health problems like heart disease, kidney disease, and nerve damage.
On the other hand, when blood sugar levels fall too low, it can lead to hypoglycemia, which can cause symptoms like shakiness, dizziness, confusion, and fainting. In severe cases, it can lead to seizures or coma.
Maintaining healthy blood sugar levels is important for overall health and preventing chronic health conditions. This can be achieved through a healthy diet, regular physical activity, maintaining a healthy weight, and managing stress levels. If you have concerns about your blood sugar levels, it’s important to consult with a healthcare professional for personalized advice and guidance.
