Nausea During Pregnancy- Why Do Women Suffer Morning Sickness?

Nausea During Pregnancy- Why Do Women Suffer Morning Sickness?

Nausea (also called morning sickness) is one of the most annoying pregnancy related conditions, and definitely one of the most common. Many women suffer from this sickness in one form or other, causes by the increasing levels of hormones circulating in the blood.


Many theorize that the rise in the pregnancy hormone hCG, one part of which at a microscopic level resembles thyroid hormone, causes nausea in a way similar to the way hyperthyroidism can cause it. Others think it’s the estrogen, is responsible to increase blood flow to the taste buds and affects taste and cravings negatively as well as positively. Since taste is almost identical to smell, this would explain the reason some smells set off a wave of nausea. Another reason for nausea is the rapid expansion of the uterus.

Surprisingly, some expectant women never suffer from nausea during their whole pregnancy period. Conversely, many women suffer greatly; even they need to get admitted into hospital immediately to keep hydrated with IV solutions. When nausea gets too bad, it is referred as Hyperemesis Gravidarum, which is a vicious cycle: nausea reasons dehydration, and vice versa dehydration degrades your current stage of nausea, and further this nausea causes further dehydration. This sequence can be broken by rehydrating with simple overnight IV, which is often enough to get a women stable enough to begin eating again.

How Long The Symptoms will Lasts

Nausea is the most common complaint of the first three months of pregnancy. One-third of pregnant American women are affected with vomiting or digestive disturbance but it usually stops at the end of the first trimester. Nausea actually can be any time and can even last all day long (and all night too). Usually when the amount of rising hCG plateaus (at about ten weeks), the nausea subsides. Improvement will be gradual: the nausea and vomiting won’t clear up dramatically in one day. Good days will gain over bad ones until there are fewer and fewer bad days and the nausea finally disappears. There are exceptions, with lingering into the second trimester, but this time the nausea is much more tolerable.

Management of Pregnancy Nausea

There are few feelings as bad as the feebleness of nausea, and on one point the practitioners find reassurance in this misery because it means the hormones are intense and the pregnancy is perhaps strong. But the nutritional shutdown is never normal. The dehydration is never normal. And it happens that a lot of the suffering goes unimproved in spite of practitioner’s best efforts. Both the non-prescription remedy and a handful of prescription drugs help to struggle with nausea. Emetrol, that is an over- the- counter mixture of sugar syrups and phosphoric acid, which acts as the soother for the actual wall of the gastrointestinal tract to reduce nausea. Here are few other ways of manage your pregnancy nausea:

  • Do not allow yourself to get too hungry. Eat smaller, more frequent meals and snacks more often. An empty stomach can cause nausea more badly.
  • Do not force yourself to eat foods that make you gag.
  • Choose stomach friendly foods like yogurt (a good source of vitamins B), low-fat, and high carbohydrate foods (starches).
  • Do not overeat. Having stuffed belly will only add to your feelings of nausea.
  • Do not have fluids on mealtimes. Some women find that eating and drinking trigger at the same time can trigger nausea. Just make sure you make up for those lost fluids at the other tomes of the day, since dehydration can also cause nausea.
  • Watch when you are taking your prenatal vitamins. If you are taking it on an empty stomach, you are asking for trouble. Try making it in the middle of a meal instead.
  • Prescribe Compazine, Phenergan, Tigan, or Reglan.
  • Prescribe Zofran.
  • Parental hydration is an important issue. Parental hydration word refers administering by intravenous route (i.e., by an IV infusion). The dehydration from nausea and vomiting can make nausea worse. Usually one night stay in the hospital with physiologic solution by IV can redeem a sever nausea.

Additional Tips to Manage Pregnancy Nausea

Here are some more tips to coping with your nausea:

  • Try until you find one or more foods that tempts to you. You may discover that certain categories of foods –salty, bitter, crunchy, sweet, hit, cold, or thick, etc. also appeal.
  • Avoid greasy, spicy foods as well as hard to digest food such as sauces, onion rings and fatty fried foods.
  • Avoid pants with belts and other types of tight-fitting clothing. They will only add to your discomfort.
  • Carry around a piece of lemon or mint leaves or grated ginger root. Some ladies find that smelling one of them helps to settle their heaving stomach.
  • Mid-Morning snack of a banana helps many women.
  • Drink very hot or very cold liquids: the extreme temperatures may make you feel better.

It is not easy to think that if your feeling so ill due it must mean there’s something wrong with your pregnancy, but quite opposite is true: Studies have shown that women with little or no morning sickness with nausea and vomiting are two to three times as likely to miscarry as those who are feeling totally wretched. What’s more, they’re less likely to experience a premature birth.
