What is the cause of pregnant women vomiting blood?

Gastrointestinal bleeding

Vomiting blood is a phenomenon of gastrointestinal bleeding, which can be seen in gastric ulcer bleeding, esophageal varicose vein bleeding caused by liver cirrhosis, etc. Therefore, if you vomit blood, you need to check for the above diseases and actively treat them symptomatically. Secondly, it depends on the amount of bleeding. If it is a phenomenon of vomiting blood, it may be seen in gingivitis or pharyngitis bleeding.

Mucosal bleeding caused by severe morning sickness

Some pregnant women experience severe and frequent morning sickness, and may even vomit blood. This is mostly caused by bleeding in the mouth, throat, or gastric mucosa, such as rupture and bleeding of the esophageal capillaries due to vomiting, or forceful expansion of the gastric cardia and severe vomiting causing damage and bleeding of the gastric mucosa, etc. In general, if the bleeding is not serious, it will get better soon. Just pay attention to a light diet and avoid spicy and irritating foods. If the bleeding is severe, it is best to go to the hospital for examination and listen to the doctor's advice.

Caused by laceration of the cardia

Vomiting blood during morning sickness may indicate a ruptured cardia. This situation often occurs when vomiting is severe, the intragastric pressure increases, causing the cardia to expand rapidly, resulting in tearing and bleeding at the cardia. The focus of treatment should be to prevent vomiting again or reduce the severity of vomiting. Bleeding can usually heal on its own.

Effects of vomiting blood in pregnant women on the fetus

Affects fetal development

When pregnant women have severe morning sickness accompanied by vomiting blood, it will affect their intake of nutrients and cause a large loss of ions in the body, leading to malnutrition. The nutrients needed for the fetus's growth and development in the mother's body are all supplied by the mother's placenta. If there is a lack of nutrition at this time, it will affect the growth and development of the fetus.

In severe cases, it can cause miscarriage

If a pregnant woman vomits blood continuously or loses too much blood, the blood cannot nourish the fetus, which can easily lead to miscarriage, premature birth, intrauterine growth retardation, or even fetal death. This should be taken seriously, and the patient should be admitted to the hospital for examination, other diseases should be ruled out, and symptomatic treatment should be given.

Influence on fetal personality formation

Severe vomiting during pregnancy and vomiting blood during pregnancy often make pregnant women resist and fear pregnancy, which will cause increased corticosterone levels in the pregnant woman's body. Corticosterone molecules can be transferred to the fetus through the placenta. If the fetus is exposed to the mother's high corticosterone level environment for a long time, the receptors in the fetal brain become less sensitive. After such children are born, when they encounter emotions such as depression and anxiety, the regulation of the brain's adrenal corticosterone negative feedback loop will not be as precise and sensitive as that of ordinary people, causing the children to be timid and fragile, easily excited, and timid in action.
