Differential Diagnosis for 10 Weeks Pregnant Vomiting Blood
- Single Most Likely Diagnosis
- Peptic ulcer disease or gastritis: The most common cause of vomiting blood (hematemesis) in pregnancy is peptic ulcer disease or gastritis, which can be exacerbated by the hormonal changes and increased intra-abdominal pressure associated with pregnancy.
- Other Likely Diagnoses
- Hyperemesis gravidarum with esophageal tear (Mallory-Weiss syndrome): Although hyperemesis gravidarum is a condition of severe nausea and vomiting in pregnancy, it can occasionally lead to an esophageal tear, resulting in hematemesis.
- Gastroesophageal reflux disease (GERD): Pregnancy can worsen GERD symptoms, potentially leading to esophagitis and bleeding.
- Do Not Miss Diagnoses
- Ectopic pregnancy with rupture: Although less common, an ectopic pregnancy that has ruptured can cause severe abdominal pain and vomiting, including potentially vomiting blood, due to internal bleeding.
- Placenta previa or abruption: These placental disorders can cause vaginal bleeding, but in rare cases, they might also lead to gastrointestinal bleeding due to a disseminated intravascular coagulation (DIC) or other mechanisms.
- Rare Diagnoses
- Gastric cancer: Although extremely rare in young pregnant women, gastric cancer can cause hematemesis and should be considered if other diagnoses are ruled out and symptoms persist.
- Hemophilia or other coagulopathies: Pregnant women with underlying coagulopathies might experience bleeding complications, including hematemesis, especially if their condition is not well-managed.
- Ingested maternal blood (swallowed blood from nosebleed or gum bleeding): This can mimic hematemesis but is not due to an internal source of bleeding.
