Blood sugar, also known as glucose, is the primary type of sugar in the body. It serves as a crucial energy source for cells, including brain cells. Throughout the day, your blood sugar level fluctuates due to factors like eating, exercise, sleep, stress, and hormones.
For most healthy individuals, the normal blood sugar levels are as follows:
- Fasting (before meals): Between 70 mg/dL and 100 mg/dL.
- 2 hours after eating: Up to 140 mg/dL.
However, these targets can vary based on individual factors such as age, health conditions, and lifestyle. People with diabetes need to monitor their blood sugar levels closely to stay within the appropriate range. Here’s what you need to know:
- High Blood Sugar (Hyperglycemia):
- When blood sugar levels are too high, it can have serious health consequences, such as nerve damage, kidney damage, and heart disease.
- High blood sugar can lead to conditions like diabetes, cardiovascular disease, and stroke.
- Low Blood Sugar (Hypoglycemia):
- Low blood sugar can cause symptoms such as confusion, anxiety, weakness, sweating, and vision problems.
- Extremely low levels may result in seizures and fainting.
- Managing Blood Sugar:
- Diet and Lifestyle: Choose foods with minimal glucose impact.
- Regular Monitoring: Test blood sugar levels as advised by your healthcare provider.
- Medication and Insulin: Follow prescribed treatments if you have diabetes.
- Medical Alert: Wear a bracelet indicating hypoglycemia episodes.
Remember that there’s no one-size-fits-all “normal” blood sugar level. Your target number depends on personal health and lifestyle factors. If you have any concerns about your blood sugar, consult your medical provider for a comprehensive assessment.
