My dad takes insulin injection for diabetes but sugar level doesn't drop down what can he do?

Doctor: A doctor may need to adjust medication if blood sugars aren't responding appropriately to medication. A comprehensive history is necessary, including review of blood sugars, diet, and screen for other illnesses if necessary before such a decision is made. Your dad needs to discuss with his doctor. Better sooner than later.

More is best: Dad may need to up the dose of his Insulin under the direction of his dr.
