Obese pregnancies causing increased issues in kids? So I have a theory that the increased amount of autism/ADD/mental and physical issues in kids is due to the mothers being fat before and during pregnancy. I’m thin and live a healthy lifestyle. My 2 kids are happy, healthy, and normal. No issues. That being said, here are some situations I’ve seen.  Women A: Fat before and during pregnancy. One kid has significant mental issues and the other has physical issues.  Women B: Healthy weight first pregnancy, fat for next 2 pregnancies. First kid is normal. The 2nd kid has severe physical issues and the 3rd kid is non-verbal.  Women C: Very Obese before and during pregnancy. Kid was born early due to preeclampsia. Kid has SEVERE physical problems, ones that could kill him one day.  The mothers I know that were normal weight before and during pregnancies have healthy kids.  I truly think a lot of the increased health issues we’re seeing in kids are due to the increase in obesity. Don’t understand why this isn’t addressed by doctors more.  What are your thoughts? Any similar stories you can share?  (Obviously does not apply to every situation. But I think it’s a trend).
