Poor, poor, poor, poor you. You have my every sympathy.
Hyper - Lots of
Emesis - Vomitting
I had horrible hyperemisis (actually, there can surely be no nice hyperemisis) at the started of this pg and spent 6 weeks in bed, mostly in hospital, mostly on a drip. I couldn't keep a thing down, no food, no water, no anti sickness drugs, couldn't even brush my teeth.
Ketones are produced when you start breaking down body fat in preference to using any other food supply for energy. On the atkisn diet you do this after you've eaten the food you are allowed - this food stops the ketosis being too bad for you. If you are not managing to eat anything, basically you are starving yourself once you have ketones in your wee and it is really bad for you, ketones are toxic in concentration. I believe it is similar biochemistry to a diabetic coma.
Ketosis (having ketones in your wee) quite ofetn coems with a liver and/or kidney and/or urinary tract infection, the symptoms of which include - magically - nausea!
Most hospitals work on the basis that 24 hours of nil by mouth on a drip, and then a further 24 hours of food and drip shoudl knock hyperemis on the head, but this didn't work for me. I didn't find any of the antiemetics (anti sickness) drugs any help unless they sent me to sleep. After 6 weeks it did just stop though.
If you can manage any food or drink at all it will help the ketosis. Towards the end I found that very cold drinks, ice lollies and ice cubes were OK, and I I still munch ice lollies/cubes when I am feeling a bit nauseous now at 33 weeks. codl fizzy water too. Toast and butter was OK too, as long as the toast was hot enough for the butter to melt. A real breakthrough came when I managed jam too! And then, once I was home, I ate a lot of very thin soup. I couldn't cope with any dairy foods at all for some time though, apart from the butter on the toast.
Take a look at the hyperemisis website "Blooming Awful" too. I'll try and find a link.
