I agree 1000% with Jade. Type 2 can be cured. It takes a lot of work and discipline, especially at first, but it can be done. Diet is terribly important. Investigate the Glycemic Load. That will tell you what he can eat. Excecise is important, primarily aerobic like walking. Chiropractic care can help as well. My husband's is always exacerbated by one specific vertabrae that is not aligned properly. It allows the brain to communicate with the pancreas so it is ultimately essential that you are taking care of your spine.
Please don't be scared. Once habit sets in and he gets in a routine, you'll be fine. My Dad has been a type 2 for 43 years. Even at age 93 we can control his sugar fine. He has beautiful feet...nicer looking than mine. And everyone that meets him is amazed. He has eaten right, walked anywhere from 2 to 5 miles a day and routinely visits the chiropractor for maintenance. We still control it with diet!
God bless!
