I have an update...........Before all the news broke on singulair,my son was placed in a asthma study for adolescents,i got some very disturbing news today from the study.....his insulin level at fasting was 11....his insulin level at 2 hours after eating sugar was 238 but his glucose was within normal range...they have suggested we see an endocrine doctor......i will call his primary Monday and see if we can repeat these tests....I am hoping it was a temp effect of the singulair and not permhis hdl level was abnormal to but his cholesterol was 170....
