My mom has diebetes and about a month ago was put on injection insulin but its never controlled. her blood sugar reading is 438 and having severe headaches, nausea, ect.all drs do is lower it and its still high her readings. no matter what they do her rea

Consult endo doc: The vast majority of type2 diabetics are obese and thus highly likely/virtually all have some Insulin resistance--need more Insulin to do the same job. There are newer meds which may help, such as victoza (liraglutide) or byetta/bydureon injectables. Wt loss will help. Bariatric surgery in selected cases can be very effective. Consult endocrinologist/diabetic doc. Good luck.

Sounds complicated: Insulin always works. So something else is not right here. She may have a problem with technique ( drawing, injecting, etc) / with the Insulin (storage, type, etc.) or perhaps something entirely different. She needs coordinated care between a dm educator and physician who can jointly understand why her bg are not controlled with the best therapy we have.
