Poor Kaiser! On Thursday, Oct. 4, Teen Mom star Jenelle Evans revealed that her youngest son had to undergo some serious surgery. It turns out he was struggling with some health issues — which dad Nathan Griffith so much as said in September when he alleged that Kaiser has been “chronically sick for the past year.” 

At the time, we weren’t sure if that was true or just more of the constant call outs the exes throw at each other on Twitter. After all, back in August, Jenelle had tweeted, “If you’re so “concerned” about your son why haven’t you [called] him to see how he’s been lately? Oh yeah, you don’t care… Silly me, I forgot.” 

It turns out, though, that Kaiser was having some real issues. Hopefully now, though, they’ve got things under control. For the full story, scroll down and check out the gallery below.
