I had HG during my two pregnancies twenty seven and twenty three years ago. My obstetrician didn't take me seriously when I said I was vomiting up to 50 times a day - he said it was normal. I lost 7 kilos in the first trimester and was allergic to medication that stops vomiting. I cannot even hold down water and vomited until my throat was lacerated and was vomiting blood. I went in and out of hospital for drips when I got really dehydrated. I was vomiting until my 36th week but I ate like an elephant - I didn't care that it was mostly coming out again - I wanted a healthy sized baby.
