When To Check Blood Sugar Levels

People with Type 1 diabetes using flexible insulin therapy should work with their healthcare provider to know when to check their blood sugar at home. Their health care provider may recommend that they check their blood sugar before each meal, before snacks, 2 hours after a meal and at bedtime. It is also important to occasionally check blood sugar at 3 AM to make sure they are not having low blood glucose. They have to check their blood sugar levels even if they are sick.

On the other hand people with type 2 diabetes may be advised to check their blood sugar levels at least once or twice a day before meals.

Why Diabetics Should Test Blood Sugar Levels

People with diabetes should self - monitor their blood glucose levels at home to know what their blood glucose level is at any given time. Sometimes, they may find that their blood sugar levels fluctuate without any set patterns. Some people prefer to use a continuous glucose monitor inserted under their skin in the abdomen. They should still continue to perform finger stick blood glucose testing several times a day in order to ensure that the continuous glucose monitor is working properly and is well calibrated. 

Testing blood sugar levels helps patients detect when their blood sugar levels are high or low; how their diet, such as eating more carbohydrates, and not taking enough insulin, or physical activity, such as being more or less active than usual could affect their blood glucose levels. It could also help show how physical, emotional, or unusual stress such as an infection could increase their sugar levels, and how sickness from a virus, fever or cold could increase their blood glucose levels.

People with type 1 diabetes should perform urine testing for ketones if their blood glucose level is above 240 mg/dL (13.3 mmol/L), whenever they are sick, during physical or emotional stress, or if they have symptoms of nausea, vomiting, and abdominal pain.
