Help Needed! Hypremisis!

So my partner is currently 15+6 weeks pregnant baby is all healthy and very active had had numerous ultrasounds and dopler scans to witness it. Since early pre first trimester she's suffered bad with morning sickness and was taken into day assessment unit (maternity ward) at our local hospital and after 3 visits there on numerous occasions we finally got a diagnosis of severe hypremisis and dehydration. Stating that she had ketones ++++ so she was severely dehydrated and this has happened numerous times as she cannot administer fluids or eat anything when the hypremisis is active as such! Yesterday evening I had taken her to our gp and spoke to her about all our problems with the pregnancy and that it is our first pregnancy, normal conception. She reffered us to the day assessment unit for further tests and advised hospital admissions because of the severity of hypremisis and that my partner had lost over 10% of her body weight since falling pregnant. 7th visit today Ended up being on a iv fluids for over 10 hours during the night to get her dehydrated and to ease the nausea/sickness. Discharged today with antiemetics. She is getting very down about feeling very unwell 247! Please is there any suggestions that anybody could give to help us both fight through hypremisis and get her to carry on fighting through this hard time.

Thanks!!
