My mother is suffering from type 2 and steroid diabetes glucocorticoid therapy. her diabetes is shooting to 410mg. which insulin form is good for her?

Difficult answer: Books are written on this, so there is no easy answer. The best advice i can give you is this: make sure that your mom is using the prescribed Insulin and is using it correctly.

Most require: Both fast-anolog Insulin [humalog, novolog, apidra] and longer acting Insulin [glargine, levemir] i've also written on value of using incretins in steroid diabetes.
