Nausea and vomiting in late pregnancy

   Nausea and vomiting during pregnancy commonly occur in women and are typically caused by neurological factors, human chorionic gonadotropin (hCG), fetal self-protection mechanisms, and the mother’s heightened awareness of the fetus. Since hCG levels rise significantly during pregnancy, this hormonal surge contributes to nausea and vomiting. But what about nausea and vomiting in the third trimester?

Nausea and Vomiting in the Third Trimester

Nausea and vomiting during the third trimester are primarily attributable to indigestion. As the fetus and uterus grow larger in late pregnancy, they exert pressure on surrounding organs, slowing gastrointestinal motility and predisposing the mother to indigestion. Fetal movements may also cause maternal discomfort and trigger nausea. Additionally, excessive hormone secretion can lead to heightened nausea and endocrine dysregulation—symptoms that typically resolve after delivery. However, persistent nausea, vomiting, upper abdominal pain, or other discomforts warrant prompt evaluation for acute fatty liver of pregnancy, a rare but serious condition.

When experiencing vomiting, pregnant women should promptly replenish fresh vegetables and fruits. Consuming bland, easily digestible foods—or taking vitamin B6—may help alleviate or prevent nausea and vomiting. Distraction techniques and emotional regulation can also provide some relief. In early pregnancy, digestive symptoms such as nausea, vomiting, aversion to greasy odors, craving sour foods, and decreased appetite are common manifestations of morning sickness. Some women may also experience depression, irritability, or insomnia.

Pregnant women should avoid oily, heavy, or difficult-to-digest foods and refrain from overeating, as both can exacerbate nausea and vomiting. We hope this information is helpful to you.
