GIT Achalasia & Zenker's diverticulum food regurgitation mechanisms?

Does anyone know how these entities lead to undigested food regurgitation? Achalasia leads to dilation of proximal oesophagus and nocturnal regurgitation but does anyone know of any precise mechanism etc. and what about Zenker's ? Sorry for my silly questions! Merry Christmas & a happy new year to everyone !!

That's because, in both cases, the food never made it to the stomach for digestion to occur

yup, I know that undigested food gets accumulated in the oesophagus but what is the source of expulsion of the food back into the mouth...I mean regurgitation is effortless in contrast with vomiting...
