Morning Sickness
Obstetrics 

It doesn’t matter whether you try a spoonful of nuts, toast; broth or chicken; carrots or beats —it’s estimated that 70% to 80% of Australian women who fall pregnant are affected by morning sickness. 

What is Morning Sickness?

Morning sickness is nausea and vomiting during pregnancy. Despite the name, morning sickness can strike at any time of the day.

Although the cause of morning sickness remains a mystery, research points to a combination of both metabolic and physical factors, among them:

  •     Changed metabolism of carbohydrates
  •     Lowered body pressure
  •     Changes in physical, hormonal, and  chemical caused by pregnancy

How Does Morning Sickness Work?

Every woman is affected by morning sickness uniquely. 

Morning sickness can strike at any stage during pregnancy, but most women report the problem during the first trimester.

It means that for most women, morning sickness starts around the 5th week of the pregnancy running through the 12thto 14th week. Still, 1 in 5 women experience morning sickness during the second trimester, and the unfortunate few must endure morning sickness throughout their pregnancy—nevertheless, only a few women don’t grapple with morning sickness. 

While most cases of morning sickness do not harm your baby or your health, there are extreme cases that may require hospitalization. 

Why Does Morning Sickness Occur?

Researchers are yet to determine the exact cause of morning sickness. Still, the popular theory explaining the condition is the body reactions to the pregnancy hormone, human chorionic gonadotropin (hCG), estrogen, thyroxin, and insulin are associated with nausea vomiting in pregnancy.

Apart from hormonal changes, nausea and vomiting in pregnancy are associated with external factors such as diet, age, smoking status, and bacterial infection. 

Research makes the hypothesis that hypoglycemia, nausea, and vomiting are connected to pregnancy. This is due to changes in metabolism due to the increased demands for glucose for your developing fetus.
