when does morning sickness end
Nausea and vomiting are common during the first trimester of pregnancy. About 50% of future mothers will suffer, and 25% will experience nausea only. Although sometimes referred to as morning sickness, these discomforts may be present at any time of the day.
Nausea and vomiting usually begin around the six the week of pregnancy and continue to the end of the first quarter. Some women, however, will be affected until the 20 th week of pregnancy. In rare cases, this discomfort may persist until delivery.
Usually, nausea and vomiting are safe for both mother and baby. However, if the pregnant woman fails to eat, she may run out of certain nutrients and become dehydrated.
According to experts, nausea and vomiting are likely to be due to the hormonal changes that occur in early pregnancy. Fatigue and emotional factors may also be involved.
Some pregnant women are more likely to have nausea and vomiting:
- pregnant mothers of twins or triplets;
- women who have had nausea or vomiting during a previous pregnancy;
- those whose mother or sister experienced nausea or vomiting during pregnancy;
- women who suffer from motion sickness or who have migraines;
- mothers who are pregnant with a girl.
If nausea and vomiting begin after the 9 th week, they could be a sign of a health problem. Talk to your doctor about this.
How to prevent?
It ‘s hard to prevent nausea, but some gestures can decrease the frequency and severity of nausea.
- Avoid staying too long without eating. Try to eat more often, but in smaller quantities.
- Eat lightly (e.g., toast or crackers) and wait 15 minutes before gently emerging from bed in the morning.
- Eat foods you want. For example, salty chips would help calm enough the stomach to allow you to eat.
- Avoid cooking or eating spicy, fatty or fried foods.
- Open the windows or use the oven hood to remove odors that disturb you.
- Take the air and avoid getting too hot.
- Take naps or take a few days off work if necessary. Fatigue can exacerbate nausea.
If multivitamins increase your nausea, try taking them with food or just before bedtime.
Some alternative treatments can help relieve nausea and vomiting.
- Ginger would have a calming effect on the stomach. Studies have shown that it is effective in reducing nausea. It is suggested to take capsules of 250 mg of ginger, four times a day. However, their effectiveness varies from one brand to another. It is, therefore, best to seek advice from the pharmacist. Fresh ginger or an infusion of grated ginger would also be effective, but it is then harder to control the dosage.
- Vitamin B6 supplements can also help relieve nausea from pregnancy.
- Acupuncture and acupressure would have some efficacy to decrease nausea and vomiting. There are unique bracelets that put pressure on a specific point on the wrist.
It is important to avoid dehydration. Be sure to drink small amounts of water frequently.
What if vomiting is caused by gastroenteritis?
To prevent dehydration, you can take a rehydration solution (e.g., Pedialyte® and Gastrolyte®). On the other hand, medications to reduce vomiting, such as dimenhydrinate (e.g., Gravol®) should only be used after talking to a pharmacist or doctor as they cause drowsiness.
To determine whether or not drug therapy is necessary, it is important to assess the extent to which daily activities are affected by nausea and vomiting. Rapid treatment of nausea and vomiting can prevent several complications in the mother, including hospitalization, and help her resume her daily activities.
The most common drug treatment is Diclectin®. This medication is composed of an antihistamine and vitamin B6. It is available only under prescription.
According to Health Canada, this drug is effective in relieving nausea and safe for the baby. Studies have concluded that Diclectin® does not constitute a danger to the unborn child. However, some researchers have raised concerns about the use of this drug and some congenital malformations such as pyloric stenosis. According to the IMAGe center of CHU Sainte-Justine, even if this association were real, the risk for the fetus would remain very low. The Society of Obstetricians and Gynecologists of Canada (SOGC), for its part, maintains that Diclectin® is a safe medication for treating nausea and vomiting during pregnancy.
Women who vomit much should rinse their mouth with a solution of baking soda (1 tsp in a cup of water). This will neutralize the acidity from the stomach that might attack the tooth enamel.
When nausea becomes extreme
In some women, nausea and vomiting can become so severe that the health of the mother and baby is at risk. This is called hyperemesis gravidarium . 1 to 3% of pregnant women would be affected by this condition.
Consult your doctor if:
- nausea or vomiting are detrimental to your activities;
- you lose weight;
- you show signs of dehydration such as dryness of the mucous membranes (mouth, nose) and dark urine;
- your vomiting is substantial and persistent.
- Women who suffer from hyperemesis gravidarium will need treatment to stop vomiting.
- They will also need to be fed and hydrated. In some cases, hospitalization may be necessary.
