Hi Ginpin,
I too suffer with this but am in my early 50's.My issue is simply stomach acid,I produce alot.This sounds similar to your Mum.I literally feel like I have morning sickness if I don't take my Emoprezole(Nexium) as soon as I wake up.Could you speak to a doctor or pharmacist.You can buy Nexium over the counter,but obviously check with docs first.It could be that her stomach is still sensitive after her recent illness.I also have diverticulitis but that doesn't cause my morning issues.I have also found that drinking green tea or any tea that doesn't need milk,first thing in the morning, helps.In general I keep my Emoprezole and a glass of water next to the bed,as soon as I'm awake I take it,and no more nausea for me.It could be the tail end of her bug making her stomach sensitive.I would definately consult someone about taking Nexium,or similar,even if it was just for a trial period.Hope she feels better soon,I do empathise x
