I think her condition is most probably “gastroparesis” from the way she’s describing it. It can also cause GORD “gastro oesophageal reflux disease” where the stomach acid leaks out and into the oesophagus. She always says it’s “a rare stomach condition” but I’ve come across it a lot in my experience. Obviously it’s a really nasty condition and I do feel for her, however she definitely milks it for all it’s worth and is desperate for sympathy. Anyone else would try their best to get on with their life and live life to the full but not our babyprincess
