Defining “Insulin” and “Metformin”

Two of the major treatment options for diabetes are insulin injection and metformin medication. Both of these treatment choices are prescribed based on the needs of the patients and the severity of the condition. Let us know the differences between these treatments and how they are effective enough in their purposes.

Metformin is a form of oral medication for diabetes. It only treats people who are diagnosed with type 2 diabetes. This medicine should be paired with a healthy diet and proper exercise to get all the benefits that the body needs in controlling its blood sugar levels. Oftentimes, it is combined with insulin for a better effectiveness rate in preventing diabetes and slowing its infectious range.

Meanwhile, insulin is characterized as a natural hormone that helps in stabilizing the body’s blood glucose levels. In terms of treating diabetes, this hormone provides the needed medical therapy for people with both type 1 and type 2 diabetes. Individuals with these conditions need enough insulin support to stop the abnormal state of their blood sugar. Aside from that, insulin can prevent other health complications from happening.
