Dear Seansmom,
As you may have already seen posted, left ventricular hypertrophy (LVH) in an infant of a diabetic mother can be seen if the
blood sugar control during the pregnancy is not ideal. The extra
sugar goes across the placenta, but your insulin doesn’t. Thus, your son’s pancreas had to increase its own insulin production. When this happens, the insulin acts as a growth factor. It causes these babies to be larger than normal. It also causes the heart muscle to become thicker.
