How Basal Insulin Works
Basal insulin mimics the constant low level of insulin your body normally produces. It helps control blood sugar between meals and during sleep. This type of insulin is typically injected once or twice a day, depending on the specific kind used. By providing a steady background of insulin, it helps your body better manage glucose levels.
Types of Basal Insulin
There are several types of basal insulin available. These include NPH insulin, insulin detemir, insulin glargine, and insulin degludec. Each has slightly different properties in terms of how long they last and how evenly they work. Your doctor will help choose the best option based on your individual needs and lifestyle.
Starting and Adjusting Basal Insulin
When beginning basal insulin, you'll start with a low dose and gradually increase it based on your blood sugar readings. This process, called titration, helps find the right dose for you. It's important to check your blood sugar regularly and work closely with your healthcare team during this time. The goal is to find a dose that keeps your fasting blood sugar in the target range without causing low blood sugar.
