Can insulin be orally administered to diabetic people or not ? Why?

Dear student 

Kindly refer the solution below to the asked query 

No,  insulin cannot be administered orally because it is a protein and will get digested by digestive enzymes released in gut before it is absorbed in blood stream. 
Hence, it should be taken by injection. 

Hope this information clears your doubt about the topic.
