Vomiting and Nausea During Pregnancy

Vomiting and Nausea During Pregnancy

Last update: 18 September, 2017

Vomiting and nausea during pregnancy are especially common symptoms. Generally these types of experiences are associated with pregnancy even when the person isn’t pregnant.

Vomiting and nausea are certainly uncomfortable to go through, and sometimes related to the health of the pregnancy.

The first trimester of pregnancy is the most complex in this aspect; some women are more affected than others.

These symptoms can often appear well before we know the happy news.

They rarely persist throughout the pregnancy, but in the first days they can ruin our mornings. They are common during breakfast or just as we’re stepping one foot out of bed.

Most future mothers deal with this issue at some time in their pregnancy. Still, us knowing that it is a common process doesn’t mean that we need to suffer silently or that there’s nothing to be done.

Specialists and other mothers have found solutions and remedies for this type of response. We’ll let you know how to make this situation better.

Causes of vomiting and nausea during pregnancy

It’s not likely that we can avoid these annoyances happening when we’re pregnant. Normally they are due to a rise in the production of hormones like human chorionic gonadotropin (HCG).

This hormonal increase is provoked by the fertilization of the egg, and at a later stage, the development of the placenta also provokes it.

During the first months this adaptation keeps the production of said hormone raised. This is why the discomfort that we suffer from vomiting and nausea happens in the first stage.

It is possible to experience these symptoms in other stages of the pregnancy, but normally they reduce  gradually  as the process continues.

Chorionic gonadotropin, just like progesterone, is a hormone that enhances the relaxation of the digestive system. As a result of this, reflux becomes more common. These hormones also affect the stimulation of the emetic areas of the brain, which can produce vomiting.

Advice on What To Do in Case of Vomiting and Nausea

As we’ve said, it isn’t easy to avoid all of these hormonal changes happening, but we can take some measures which help to minimize the symptoms.

Although this condition is normal, sometimes it needs to be managed not only to avoid the discomfort, but because it can have unwanted consequences.

If a pregnant woman has been vomiting intensely, periods of dehydration may occur. She can also begin to suffer from nutritional deficiencies due to the fact that a large part of her food is being lost.

In some cases, it may be necessary to see a doctor to help with recovery. Otherwise, the following tips can help us feel better.

  • Cookies or crackers can help in the early morning. If you experience this discomfort upon waking up, it helps to have some crackers on hand. Eat a few before getting out of bed, and this will offset your low blood sugar.
  • You can eat breakfast normally after the crackers you ate ten minutes before getting out of bed. However, drinking liquids is not recommended at this time. If you are planning on drinking coffee or juice, it is suggested that you wait until three hours after having eaten solid foods.
  • Avoid heavy meals. It is preferable to have several small meals rather than one large one. It is also not good to go many hours without eating, since gas is damaging in these cases.
  • Remember to limit your activity, since vomiting and nausea cause fatigue.
  • It is recommended to replace the water and salt that you have lost after intense periods of vomiting; so remember to stay hydrated throughout the day.
