How often should I check my blood sugar levels?

The frequency of checking blood sugar levels can vary widely depending on your type of diabetes, your personal management plan, and your doctor's recommendations. For those with Type 1 diabetes, the American Diabetes Association suggests checking blood glucose levels four or more times per day, including before meals and snacks, occasionally after meals, at bedtime, before exercising, when correcting a high blood sugar level, and before critical tasks such as driving. For people with Type 2 diabetes, the frequency might be less, potentially once per day or even less frequently depending on your treatment plan and blood sugar control. Some individuals might use continuous glucose monitors that provide real-time glucose readings. However, these are general recommendations and it's crucial to work with your healthcare provider to establish a testing routine that's tailored to your personal needs.
