deliberew Welcome. I am glad you have got meds, but while I am not medically trained, I never heard of Hyperemesis being diagnosed via a blood test before. These days they don't usually have the strict definition about weight loss they had before, but two stones' weight loss sounds dramatic.I so agree with others, do invest in some kesostix, online or from a chemists, to check for ketones. They take these seriously at hospital. You may be dehydraed and need fluids as others say. The number for Pregnancy Sickness Support is 024 76538 2020. They will ring you back with good advice about effective meds. Also, as I always say, a good anti acid like Ranitidine can make a huge difference. Some fluids that might help: Flat full sugar coke, ice lollies, ice cubes, the juice of tinned fruit, fizzy water, soda water, Dr Pepper, Lucoazade, fizzy orange, lemonade, orange squash, orange juice (if not too acid), Robinson's fruit drinks and sips of chocolate milkshake(maybe soya). Foods of a sort include cuppa soup, Scotch pancakes, nibbles of chips and crisps, tinned fruit, slices of melon and mango, baked potatoes and cheap ice cream.
tinyradish Thank you for asking. Don't worry about me. I suffered years ago. My daughter is grown up now and I am Mother Hen on this thread.
