Hello and welcome to HCM.
As a specialist,i must assure you that your husband's sugar is very high.
It's not safe to wait for 8 hours. Ideally, he should be getting
insulin injections, to control the blood sugar.
His age and other medications being taken,should be mentioned.
He should be checking urine routine, ketones, and micro-
albumin,blood ,hemogram,
creatinine,
HbA1C,FBS,uric acid,sodium,potassium,PP2BS,CXR,and ECG. According to reports,specific treatment will be advised. Wishing him a speedy recovery.
