’16 & Pregnant’ Star Autumn Crittendon Dead at 27, Recent Health Issues

Autumn Crittendon of “16 & Pregnant” fame has died — and it sounds like there were some health problems her family was aware of … TMZ has learned.

The MTV star’s sister broke the news on Facebook Sunday — penning a heartfelt message to her late sibling … which has since been deleted. However, a source with direct knowledge has given us a bit more insight into what happened, and it sounds like a freak thing.

We’re told Autumn passed away Saturday at a home she was living at with her kids, her mom and her stepdad in Henrico County, Virginia. Our sources say her stepfather found her unresponsive in her bedroom, and that paramedics arrived and attempted to render CPR.

Unfortunately, those life-saving efforts were unsuccessful — and in terms of what may have caused this, we’re told the family still doesn’t know for sure. However, we are told that Autumn had been complaining of heartburn of late and expressed interest in seeing a doc.

Our sources say she was also diabetic and was having kidney issues of late as well … not to mention problems with her blood pressure. Bottom line … it’s unclear what caused her sudden passing.

Autumn was best known for appearing on season 5 of “16 & Pregnant,” which documented her giving birth to her eldest son, Drake, who she welcomed with then-boyfriend Dustin Franklin. Autumn had three children in total.

There’s been another recent ’16 & Pregnant’ tragedy — we broke the story … Sean Garinger was killed in an ATV accident, and he too left behind little ones.

Autumn was only 27.
