Morning Sickness

"Damn it! The kids got into my stash!" That was my first thought as I saw the open container in the kitchen. I really need to find a better hiding spot. At least they didn't take it all. This stuff is sooooo good. It is probably addictive, but I don't care. I got it from a co-worker's daughter's boyfriend. Apparently, he is part of the syndicate that produces this high quality product. I don't ask too many questions. I'm just glad I've got a connection when I need my next fix.

Consuming my new found favorite vice is wonderful, but when I run out, I don't feel great. Pregnancy can be a wonderful time for many women. However, up to 85% of pregnant women experience morning sickness. Morning sickness is more properly called nausea and vomiting of pregnancy as it can happen at any time of the day or night. Morning sickness is considered a normal, if annoying, part of pregnancy. It can be more than just annoying, though. The Society of Obstetricians and Gynaecologists of Canada describes the nausea and vomiting of pregnancy to be about as severe as a typical patient experiences during cancer chemotherapy. We don't really understand why morning sickness happens. It probably involves genetics, hormones, things in the pregnant woman's environment, factors in the gut and the pregnant woman's psychosocial situation. One interesting theory says morning sickness is a defense mechanism. Meat, fish, poultry and eggs are some of the foods most likely to trigger morning sickness. All of these foods could carry pathogens that cause infectious diseases. In our evolutionary past, these foods could potentially have harmed the fetus. There are other researchers that claim that some women with morning sickness have lower risk of miscarriages and preterm deliveries. That is also interesting, but not universally accepted.

About half of pregnant women develop morning sickness by 6 weeks gestation. Virtually all women have at least some symptoms of nausea and vomiting by 9 weeks gestation. Fortunately, most women have the symptoms of morning sickness go away by week 16. An unlucky 10% of pregnant women have nausea and vomiting that last beyond 20 weeks of gestation. Morning sickness really is a misnomer. The nausea and vomiting of pregnancy can happen at any time of the day or night or it can be constant throughout the day.

Hyperemesis gravidarum is a serious condition that affects 0.3 to 2% of pregnant women. It is vomiting during pregnancy that can't be stopped. The vomiting starts in the first trimester and can continue throughout the pregnancy. This type of continuous vomiting is not a normal part of pregnancy. The continuous vomiting can lead to dehydration, electrolyte disturbances, nutritional deficiencies and maternal weight loss. Hyerpemesis gravidarum can threaten the life of mother and fetus.

To reduce morning sickness, the pregnant women can try to eat small, bland, frequent meals. She can avoid fried and spicy food and drink small amounts of fluid regularly between meals. In general, if something makes the pregnant woman nauseous, she should avoid it. For my wife, the smell of cooking ground beef was a trigger. Unfortunately, that was harder to avoid than you'd think, as she was working in a kitchen when she was pregnant with Emily. Also getting lots of sleep seems to help morning sickness symptoms.

Prenatal vitamins can be a trigger for some women. The problems are often due to the large table size and the iron content. If your prenatal vitamin is making you nauseous, call your pharmacist. In conjunction with your doctor, we can usually find a work around. Depending on your case, we might give you a tiny folic acid pill by itself for a few weeks. Or maybe we can give you a multivitamin without iron in it.

There have been some studies of using accupressure to treat morning sickness. Look at your wrist. Start at the crease below your palm and go three finger widths towards your elbow. Push the fourth finger down in the middle of your forearm between the two tendons you feel there. This is the accupressure spot to prevent nausea. You can try pushing there for about 5 minutes every fours hours. Or you can try placing a Sea-Band there continuously. People have had success with each, but it is uncertain if either of these methods are more effective than placebo. However, they are safe and inexpensive.

If medication is needed for morning sickness, the drug of choice in Canada is dicletin. Dicletin contains 10 mg of pyridoxine (Vitamin B6) and doxylamine (an antihistamine). If a woman wants to try something without a prescription, she can try Vitamin B6 (pyridoxine) by itself. Gravol or dimenhydrinate is safe and effective for morning sickness, but it is generally considered second line if someone fails on Dicletin. Ginger may also be effective in reducing morning sickness. There are some theoretical risks of ginger affecting the fetus as there are cytotoxic chemicals in ginger. However, there appears to be no harm to the fetus if the daily dose of ginger is kept at under 1 g per day.

Ginger isn't my flavor of choice. It is maple. To be more specific Sunshine Valley's Maple Creamed Honey. It is produced by Ash Apiaries from Gilbert Plains, and it is divine. Maple creamed honey on a bagel, cracker or peanut butter sandwich is something you really have to experience yourself. So now I have two problems. Where to hide my jar of maple creamed honey so my kids won't keep stealing it and deciding how much I like lemon. Apparently, Ash Apiaries makes a lemon creamed honey too. Mmmmm, lemon.

As always if you have any questions or concerns about these or other products, ask your pharmacist.
