On an average, morning sickness lasts anywhere from three weeks to three months. Some women hardly feel nauseous while others feel sick right up to their pregnancy. However, it is rare that a woman feels nauseous throughout – at the most eating something or a certain smell may trigger nausea.

Each woman is different. Most feel relief after they start their second trimester. Some don't.
I was extremely sick for the first 22 weeks of my pregnancy. So much that I was in the hospital three times and lost over 25 pounds. The doctor's kept telling me it would get better. First they said once I got past three months. Then they said after I start to feel the baby move. Now they tell me that I will feel better after the baby is born.
If you are still sick after three months, be sure to ask your doctor about Vitamin B6. My doctor finally found that a combination of Vitamin B6, Unisom and Phenagren every six hours has worked wonders for me. After 22 weeks of not eating well and vomiting and diarrhea, I finally can eat three meals a day along with snacks and it stays were it is supposed to.
Good Luck!

Morning sickness, also called nausea, vomiting of pregnancy (NVP) or pregnancy sickness, affects between 50 and 95 percent of all pregnant women as well as some women who take birth control pills or hormone replacement therapy. The nausea can be mild or induce actual vomiting. In extreme cases, known as hyperemesis gravidarum, hospitalization may be required to treat the resulting dehydration.
Morning sickness can occur at any time of the day, though it occurs most often upon waking, because blood sugar levels are typically the most depressed after a night without food.
Morning sickness usually starts in the first month of the pregnancy, peaking in the fifth to seventh weeks, and continuing until the 14th to 16th week. For half of the sufferers, it ends by the 16th week of pregnancy. It may take the others up to another month to get relief. Some women suffer intermittent episodes throughout their pregnancy.
[edit] Causes
There is insufficient evidence to pin down a single (or multiple) cause, but the leading theories for proximate causes include:
* An increase in the circulating level of the hormone estrogen. Estrogen levels may increase by up to a hundredfold during pregnancy.
* Low blood sugar during pregnancy.
* An increase in progesterone relaxes the muscles in the uterus, which prevents early childbirth, but may also relax the stomach and intestines, leading to excess stomach acids.
* An increase in human chorionic gonadotropin.
* An increase in sensitivity to odors, which overstimulates normal nausea triggers.
As for root causes, this issue is still somewhat controversial. A notable current scientific hypothesis is that morning sickness exists as a safeguard for the embryo's health. Biologists Gillian V. Pepper and S. Craig Roberts have done a study that indicates that the intake of alcohol, sugar, oils, and meat can trigger morning sickness. This then acts as a way of discouraging ingestion of less healthy foods.[1] According to Margie Profet, eating vegetables may be a factor as well.[2] Vegetables produce a small amount of toxins to deter insect infestation and while these toxins are normally harmless to adult humans, they are potentially dangerous to embryos.[3] Additionally, morning sickness begins at the point when the embryo's organ systems are being laid down and the embryo is most vulnerable to birth-defect inducing chemicals, but is growing slowly and has only a modest need for nutrients. By the 14th-16th week, when morning sickness typically wanes, the organ systems of the embryo are mostly complete and the most prominent need is now nutrients. Women afflicted by morning sickness typically avoid "bitter, pungent, highly-flavored, and novel foods," foods which are likely to contain toxins. Foraging people are at an unusually high risk of ingesting plant toxins, due to wild plants being a substantially larger part of their diet than civilized people's. Thus, morning sickness offers an evolutionary advantage, as studies have shown that women with more severe morning sickness have less chance to miscarry as well as less chance to have children with birth defects (see below), which explains its prevalence among most women and why it is a universal phenomenon across the human race.
Many other non-scientific theories for morning sickness have been proposed in the past. Notably, according to psychologist Sigmund Freud, morning sickness is the result of the mother's loathing of her husband. The subconscious manifestation of this is a desire to abort the fetus through vomiting.[3] In general, such theories are not accepted by modern scientists.
[edit] Treatments
Treatments for morning sickness typically aim to lessen the symptoms of nausea, rather than attacking the root cause(s) of the nausea. Treatments include:
* Avoiding an empty stomach.
* Eating five or six small meals per day, rather than three large ones.
* Ginger, in capsules, tea, ginger ale, ginger beer or ginger snaps[4]
* Vitamin B6 (either pyridoxine or pyridoxamine), often taken in combination with the antihistamine doxylamine (Diclectin®).
* Lemons, particularly the smelling of freshly cut lemons.
* Accommodating food cravings and aversions.
* Eating dry crackers in the morning.
* Trying the BRATT diet: bananas, rice, applesauce, toast and tea.[5]
* Drinking liquids 30 to 45 minutes after eating solid food.
A doctor may prescribe anti-nausea medications if the expectant mother suffers from dehydration or malnutrition as a result of her morning sickness, a condition known as hyperemesis gravidarum. In the US, Zofran (ondansetron) is the usual drug of choice, though the high cost is prohibitive for some women; in the UK, older drugs with which there is a greater experience of use in pregnancy are preferred, with first choice being promethazine otherwise as second choice metoclopramide, or prochlorperazine.[6]
[edit] Thalidomide tragedy
Further information: Thalidomide#Tragedy
Thalidomide was originally developed and prescribed as a cure for morning sickness in Great Britain, but its use was discontinued when the drug's teratogenic properties came to light. The United States Food and Drug Administration never approved thalidomide for use as a cure for morning sickness.
[edit] Research
A recent Canadian survey conducted by researchers at the University of British Columbia and the University of Victoria suggested that the use of medical marijuana may be effective in combating morning sickness,[7] although the researchers noted that their survey was not conclusive.[8]
[edit] Associations with miscarriage risk
Studies have shown that women who suffer from morning sickness are less likely to have miscarriages as well as less likely to give birth to a baby with birth defects.[3] Other doctors disagree with these links and claim that the mother's sensitivity to the changes in her body is not a variable that indicates risk of miscarriage.[citation needed] It is also mentioned that many women having a molar pregnancy or an ectopic pregnancy suffer strong nausea.
