Introduction
Nausea and vomiting after five months of pregnancy are typically caused by indigestion. If the pregnant woman has a gastrointestinal disorder, it may trigger vomiting; alternatively, elevated blood pressure can cause dizziness and vomiting. Blood pressure should be measured promptly, and she should visit a hospital to rule out gestational hypertension syndrome. Additionally, nausea and vomiting after five months of pregnancy may also result from a common cold, especially if the woman fails to keep warm adequately.
Fetal movement is a primary indicator of fetal well-being. Each pregnant woman experiences fetal movement differently. Generally, subtle fetal movements can be felt around the fourth to fifth month of pregnancy. As the fetus grows, these movements typically become more frequent. However, some women notice a decrease in fetal movement frequency—so what causes nausea at five months’ gestation?
What Causes Nausea at Five Months’ Gestation?
Nausea and vomiting occurring after five months of pregnancy are usually attributable to indigestion. If the pregnant woman has pre-existing gastrointestinal disorders, these may trigger vomiting; similarly, elevated blood pressure can cause dizziness and vomiting. Blood pressure should be measured promptly, and medical evaluation sought to rule out gestational hypertension syndrome. Nausea and vomiting during the fifth month may also stem from a common cold—especially if insufficient warmth is maintained, particularly in the lower limbs and feet. Following a cold, the stomach is especially prone to feeling cold, which may precipitate vomiting. In such cases, consuming easily digestible congee (rice porridge) may help alleviate nausea. Additionally, hormonal fluctuations contribute to these symptoms, but they are transient and typically resolve spontaneously—there is no need for excessive concern.
If nausea and vomiting suddenly appear at five months’ gestation, consider whether they result from progressive uterine enlargement compressing the stomach, thereby reducing gastric capacity and triggering nausea and vomiting. Alternatively, inappropriate dietary habits—such as consumption of spicy, cold, greasy, or otherwise irritating foods—may provoke gastrointestinal discomfort. Under medical guidance, digestive aids such as Jianwei Xiaoshi Pian (Gastric-Regulating Digestive Tablets) or Dashanzha Wan (Hawthorn Pills) may be used. Probiotics—including Zhengchangsheng (a probiotic formulation) and Siliankang—may also be taken to modulate gut microbiota and support digestion.
It is recommended that pregnant women prioritize adequate rest and avoid overexertion. Simultaneously, attention should be paid to diet: emphasize fresh vegetables and fruits, which help mitigate nausea and vomiting associated with pregnancy, support healthy fetal development, and enhance maternal physical resilience. We hope this information proves helpful.
