Dear Laura,
My thoughts go out with you and I am so sorry you had to endure hyperemesis. I have much to say, so feel free to write me with any questions. It would have really helped me to have someone who had been through it, so i can also pass along my phone number. (I had many people think I was "just" having morning sickness!!!!)
I had hyperemesis with both of my pregnancies and wrote this exact same e-mail last year asking for help/advice from people who really had 'been there.' My second daughter was born 10 weeks ago and I was sick or in the hospital for the first 16 weeks of the pregnancy. My oldest daughter was almost two at the time.
I wish I could tell you it won't happen this time, but most likely it will. Statistically, it is 80%, but I will pray that you are okay. I don't say that to worry you, but I think it helped me to know so I could prepare. These are the things I would do:
1) Ask anyone in your families if they could come stay with you to take care of the daily duties/child care if you get ill again. I was a stay-at-home mom with an toddler and bedridden or in the hospital! :-< My mom flew to Maine for a month to care for my daughter (almost two at the time). When she left, we had friends and babysitters help out. Have numbers to a nanny service or child care provider, too, just in case.
2) Begin eating now. Gain a little weight if you can and stay hydrated so when/if it starts you and the baby will be okay.
3) When you meet with your doctor, have your records from your previous hyperemesis treatment and see if you can start meds right away at the FIRST sign of morning sickness. I have heard it keeps the worse of it at bay. It didn't work for me, but I think I waited to see if this was really "It." I used suppositories.
4) Talk to your doctor right away about hyperemesis and make sure they would be willing to admit you when needed. Get numbers and directions for how to call the hospital and put on the fridge for your husband or family. (If you were like me, I was unable to do the simplest things.) Go to the doctor as often as possible. They can make you feel better and get you hydrated. Don't be shy for asking for help!!
5) Stock your kitchen full of those foods that would be edible. Crackers, gatorade, peanut butter, etc.
6) Talk to your son (if he understands) that mommy may get sick, but she will be okay. This sickness really scared my daughter this summer and my mom and I always had to talk with her about why I was always throwing up and in the hospital, etc... Even now, she will ask me, "Mommy's tummy all better?" It's remarkable how much she comprehended.
7) Have a SERIOUS talk with your husband. Is he supportive? Helpful? Make him know it probably will happen again and how much more work it will be this time with a child to take care of, too. Also, talk with him about the dangers and how to handle emergencies. (I passed out in the kitchen one evening and he had to call 911. We knew exactly which neighbor to call for my daughter, etc. It possibly saved my life that he called 911.)
8) Talk with your job, friends, family etc. Let them know what it is and give them the website http://www.hyperemesis.org/
They need to take it seriously.
9) Possibly ask really good friends and family to be available with casseroles when you are not well. Your husband and son have to eat.
Just reach out when you can and please feel free to call/write if you need any support. I know 14-16 weeks doesn't sound like a lot on the outside, but when you feel that ill it seems so scary. You are not alone. Good luck and thinking of you, Dana
