How do blood sugar tests work?
One of the best ways for diabetics to understand their condition is to regularly test their blood sugar. By doing so, people with diabetes can learn how their blood sugar responds to certain foods, medications and physical activities. Keeping a record of these changes will allow the user and their doctor to create a plan to manage the condition.
Diabetics must test their blood sugar regularly in order to fully understand how their condition reacts to different foods, medications and activities. Keeping track of these changes help people with diabetes develop a plan with their doctor to manage the condition.
Personal tests use a lancet to draw blood by pricking the skin, usually on a fingertip. A device known as a glucometer is then used to measure the user’s current blood sugar levels.
People with diabetes must test their blood sugar regularly to monitor any sudden changes. Doing so will make it easier to keep the levels in the target range set by their doctor.
