What Causes Nausea During Pregnancy






What Causes Nausea During Pregnancy Being pregnant is an amazing experience but when you feel nauseous it can be uncomfortable and frustrating and generally spoil the fun. Nausea during pregnancy is usually one of the most complained symptoms that women report. About 70% of pregnant women experience nausea at some point during the early part of their pregnancy. It is a symptom that is common during the first trimester and could even last longer and makes people think about what causes nausea during pregnancy.

While nausea also referred to as morning sickness gives a bad feeling it could be a sign of a healthy pregnancy. Soon after your fertilized egg gets attached to your uterine lining, you start to produce a hormone known as human chorionic gonadotropin (HCG) which normally leads to nausea occurring. This could show you are experiencing the common rise in pregnancy hormones required for a healthy pregnancy.

Apart from signaling a healthy pregnancy, nausea during pregnancy could lead to the following:

  • Urges you to eat foods that comprise nutrients like those rich in carbohydrate
  • Helps to reduce the exposure of the fetus to substances in your diet that can be dangerous

Not experiencing nausea is not a bad sign either as some women do not experience it during pregnancy despite the large production of pregnancy hormones.

A lot of women wonder why feeling nauseated is referred to as morning sickness because the symptoms can occur at any time of the day. For some women they have it bad in the morning and the symptoms reduce as the day goes on while for some women they can experience the symptoms throughout the day which means the term morning sickness could be considered inaccurate. Also the effect of the symptoms also varies among women. Medically nausea and vomiting is known as morning sickness.



Why nausea occurs during pregnancy is not really clear but it is believed to be linked to a hormone produced known as the human chorionic gonadotropin (HCG) which is also known as the pregnancy hormone. When eggs are fertilized and attached to the uterine lining, the hormone is produced.

It is not known how it leads to nausea occurring, nonetheless because they both apex about at the same time it is believed they both have a connection.

Apart from this, there are other factors or triggers that are believed to be contributing factors to nausea occurring. They include the following:

  1. Estrogen Level: This is another hormone that rises fast during the early stages of pregnancy and can contribute greatly to you being nauseous.
  2. Stress: There is no proof to support this study and theory, it is believed by some researchers that some women are psychologically susceptible to experiencing nausea and vomiting during pregnancy as an unusual way to reacting to stress. It is believed that stress causes physical reaction within your body which makes nausea and vomiting occur.
  3. Having A Sensitive Stomach: Some women?s stomach are sensitive to changes that occur during the early stages of pregnancy. A sensitive stomach can find it difficult to adapt to these stages leading to nausea and vomiting occurring.

Improved Sense of Smell And Being Sensitive to Odors: When women become pregnant their sense of smell improves and becomes more sensitive.

This is why you could see a pregnant woman react to the smell of a sandwich some blocks away. Apart from this, there are certain aromas that immediately make pregnant women feel like throwing up. Some researchers attribute this to estrogen levels rising higher but they are not really sure about this.
