How do people with type 2 diabetes monitor their blood sugar? **Blood Glucose Monitors:** Blood glucose meters work by using a test strip coated with glucose oxidase, an enzyme that reacts with glucose in the blood. An electrode in the device generates an electrical signal when it detects glucose. This signal then produces a digital reading. The more glucose in the blood, the higher the displayed blood sugar level. **Continuous Glucose Monitors (CGMs):** People with type 2 diabetes can also wear continuous glucose monitors (CGMs) under the skin of their abdomen or arm. Unlike blood glucose meters, CGMs don't measure blood glucose levels; instead, they measure glucose levels in the intercellular fluid. The information is then transmitted to a monitor via sensors. So, when should people with type 2 diabetes monitor their blood sugar? How often a person with diabetes should monitor their blood sugar depends on several factors, including: 1. The type of diabetes they have; 2. Whether they are injecting insulin or taking other medications to control their diabetes. People with well-controlled diabetes who are not injecting insulin may not need to monitor their blood sugar frequently. However, it is crucial to work with your healthcare provider to determine the appropriate frequency of blood glucose testing. Type 1 Diabetes: Type 1 diabetes is also known as "juvenile diabetes" because it often develops in childhood. People with type 1 diabetes need to test their blood glucose frequently. Blood glucose testing times for people with type 1 diabetes are centered around mealtimes, including: 1. Before breakfast, lunch, and dinner 2. 2-3 hours after each meal. Type 2 Diabetes: People with type 2 diabetes who are regularly treated with insulin injections must test their blood glucose levels regularly. Again, people with type 2 diabetes should always work closely with their healthcare provider to determine the correct testing frequency appropriate for their condition. However, general guidelines recommend that people with type 2 diabetes test their blood glucose four times a day, at the following intervals: 1. On an empty stomach in the morning 2. Before meals 3. Two hours after meals 4. Before bedtime. Once a person's condition is well controlled, frequent blood glucose testing may not be necessary. Medication Types: There are many different types of medications that lower blood glucose. The type of medication a person with type 2 diabetes is taking may affect the frequency of blood glucose testing recommended by their healthcare provider.
