In the first trimester of pregnancy, nausea and vomiting are very common and are considered \u201cpsycho-biological adaptations\u201d of the pregnant woman. Among the typical symptoms, nausea is one of the first to appear and is very often associated with altered taste perception and increased sensitivity to smells.<\/p>\n
It is commonly referred to as \u201cmorning sickness<\/strong>\u201d, but its symptoms can appear throughout the day and even at night (24). The symptoms generally appear between the 4th and 9th week, peak between the 7th and 12th, and tend to disappear between the 12th and 16th.<\/p>\n Vomiting during pregnancy is a symptom that occurs especially in the first trimester and is caused by increased hormonal activity in the woman\u2019s body. This leads to a disruption in the normal functioning of the digestive system, which implements this mechanism in order to protect the fetus\u2019s growth from food contamination.<\/p>\n We speak of \u201chyperemesis gravidarum<\/strong>\u201d only when these symptoms persist beyond the first trimester or increase in intensity, with continuous vomiting, electrolyte imbalances, weight loss, ketosis, and acetonuria.<\/p>\n Typical cases<\/strong> of nausea during pregnancy usually do not pose any risk<\/strong> to the mother or the fetus. However, it can be harmful when it is so intense that it causes an excessive loss of fluids and nutrients through vomiting, resulting in a decrease in the mother\u2019s weight, creating a state of stress that may also be potentially harmful to the fetus (25).<\/p>\n To alleviate the sensation of nausea, experts have developed a series of recommendations, listed below:<\/p>\n As for nutrition, here are some very useful tips (26):<\/p>\n\n
