Her son is 5 and was diagnosed almost a year ago. He was on 14 units of levemir, split 7 morning 7 at night. His humalog ratio was 1:50. He was continually running high so their endo changed things around. He's now on 12 units of lantus at dinner and his humalog ratio is 1:30. His correction went from 1 unit for dvery 100 over 150 to 1 unit for every 80 over 150. Now he's dropping very low every night. The doctor isn't returning mom's phone calls. She things this has to do with his ratios being changed but I said no way it's the lantus. His total meal and correction insulin yesterday was only about 5 units. (He doesn't eat sugar at all as they have been told not to.) Any suggestions or thoughts? She's planning on dropping his lantus herself tonight if her phone call doesn't get returned again.
