Please don't get dejected; the future of diabetes treatment is bright. In the next few years lot of breakthrough is expected. At present only injectable insulin is the answer, inhalable insulin may be available within a years time. Regular monitoring has to be done with the help of a glucometer-no other way. Regular physical exercise is a must (in addition to yoga).
Insulin pumps are also available but they are expensive - about 1 to 2 lakhs equipment + 6-7 thousand for insulin + other disposables. Oral insulin is 3-10 years away.
