Vomiting blood during pregnancy is not normal, and you should see a doctor in case you are vomiting chunks of blood.

Vicina Lucinda, a mother of two, talks about her experience of vomiting blood while she was pregnant, “The nausea was quite intense, and I couldn’t sleep sometimes because of it. One day, I had to throw up, and I also threw up blood, and that scared me. I called my midwife the next day just to be sure, and she said that I had to keep an eye on it, but it was very common ().’’

The causes of blood in the vomit in pregnant women are the same as that of the general population i.e. people men and women who are not pregnant (3).

Common causes are likely to be:

  • Severe gastritis or peptic ulcer: Gastritis (inflammation of the stomach lining) or peptic ulcers or stomach ulcers (painful sores in the inner stomach lining) cause a burning sensation in your tummy and damage the artery. This could lead to blood vomiting. Stomach ulcers are characterized by the erosion of the protective lining of the digestive system due to a bacterial infection.
  • Esophageal varices: These are the enlarged veins in the lower esophagus (food pipe), which bleed but may not cause any pain. They could be caused due to elevated blood pressure (hypertension or preeclampsia) or alcoholic liver disease (liver is damaged due to long term alcohol exposure). If the doctor suspects this, that doctor may ask you to get admitted to the hospital immediately.
  • Tear in the food pipe: Prolonged retching can cause a tear in the esophageal lining, thereby resulting in bleeding.
  • Severe gastro-esophageal reflux disease (GORD): Stomach acids leak out into the esophagus and irritate the lining, causing it to bleed.
  • Swallowed blood: In some cases, you are likely to swallow blood that might come out as blood vomiting. A severe nosebleed could be one such example.

Less common causes are likely to be:

  • Swallowing poisons such as arsenic or corrosive acids
  • Cancer of stomach or esophagus
  • Blood conditions such as thrombocytopeniaiXA condition in which the platelet count is lower than normal, i.e., 150000/microliter (for adults). , hemophiliaiXA bleeding disorder in which the blood does not clot properly. , leukemiaiXA form of blood cancer that begins in the bone marrow. , and anemia
