Vomiting during pregnancy

Nausea and vomiting are common during pregnancy.

This is thought to be caused by the rapid increase in oestrogen levels and the beta subunit of human chorionic gonadotropin (beta-hCG).

Nausea usually begins in the 5th week of pregnancy and peaks in the 9th week. They disappear between 16 and 18 weeks. If the vomiting becomes so severe that you cannot tolerate any food, this is known as hyperemesis gravidarum.

Treatment for nausea and vomiting during pregnancy is based on hygienic and dietary measures:

• Avoid carbonated, irritating (alcohol, caffeine) or acidic drinks.
• Avoid hot drinks 
• Avoid fatty and fried foods
• Prefer mild, steamed or grilled foods
• Eat 5 to 7 times a day in small portions
• Rest in a seated position for 30-45 minutes between meals

In refractory cases, it may be necessary to start treatment with medication (usually doxylamine + pyridoxine).
