OMFG @shitatscarbble (I can see why), yes really.
I have chronic severe constipation and the stomach issues I have run down one side of my family and have been passed to one of my DC.
Biggest problem for me is that it's so severe, I get the not going to days and days then splitting my arse open trying to poop, eventually over several sessions getting most of it gone, then I end up with the shits so bad it's the yellow water kind with the odd pea sized lump.
No, I'm not a poo troll. But it feels like I have one inside me.
I don't use recipes, I just make stuff. With severe constipation like this, I have to lessen my carb intake, increase the fruit and veg and water, avoid chocolate and milk and yoghurt and non vegan/lactofree cheese.
Or make sure that bread and pasta are a very small portion per day.
I'm sorry your partner has this. I'd be grateful for a board for it but if it was on mumsnet it'd get no traffic anyway
good luck!
