Insulin pills may soon replace daily injections

For more than 100 years, scientists have pursued the idea of insulin in pill form, often described as a "dream" treatment for diabetes. The challenge has been the body itself. Enzymes in the digestive system break down insulin before it can work, and the intestine lacks a natural way to absorb it into the bloodstream. As a result, many patients still depend on daily injections, which can take a toll on their quality of life.
