Does Diabetes is a Genetic Disease?
Genetics definitely plays a role in diabetes. But in most cases, it isn’t the whole story.
Usually genetics affect how likely it is that someone will get diabetes. But whether they get it or not depends on what happens to them and/or what they do. Nature and nurture are both involved.
Before getting too far into what causes diabetes, let’s back up and talk about what diabetes is. Diabetes is a disease where sugar builds up in the blood. If untreated, this extra sugar can cause damage to eyes, nerves, blood vessels, and kidneys.
Where does this sugar come from?
After you eat, your body breaks down food into a sugar called glucose. The glucose is then released into the blood to feed your cells. Normally, a protein called insulin helps to get the glucose into the cells and turned into energy.
