An Investigation: Researchers have found that women who have diabetes and are obese before pregnancy are actually 67%  or two times more likely, to have a child with autism compared to women who are not.  The children born from these unhealthy mothers posses certain common types of deprivations such as, socialization skills along with communication skills. Surprisingly, researchers have been working on searching for genetic causes for autism and have suggestions regarding genetic mutations to make the child susceptible to autism. If statistics regarding physical health of women who are pregnant in the United States it would round up to this: 34% are obese, 16& have metabolic deficiencies, 9% are diabetic, and more than 1% of pregnancies are interrupted because the mother has high blood pressure. This tell us that, because of diabetes, insulin resistance and inflammation in the body, can make a fetus vulnerable to high glucose levels that lead to complications in brain developments. During pregnancy, sugar levels that are being submitted by the mother have to be well balanced for the fetus because of the different effects of the sugar levels being too high or low (always effects in the brain). FYI: purposes of insulin in the body
