Investigating the impact of acupressure on pregnancy nausea and vomiting (A systematic review)

Abstract

Nausea is the mental sensation implying the body's need for vomiting; vomiting, in turn, can be defined as the withdrawal of the content of the upper gastrointestinal tract as a result of contractions of the digestive tract and the walls of the chest and abdomen.Nausea and vomiting can be caused by intra-and extra-peritoneal disorders, medications, endocrine disrupters, metabolic and toxins. One of the causes of nausea and vomiting is pregnancy. During 4 to 7 weeks after LMP (Last menstrual period), nausea and vomiting are seen in 80% of pregnant women; these disorders are, generally, resolved at 20 weeks of pregnancy.
