What is wrong with vomiting blood at 6 months pregnant?

Patient's question:

Detailed medical condition and consultation purpose: 6 months pregnant
Duration of this illness: 1 day
Current general condition: Vomiting when brushing teeth
Vomiting fresh blood
Medical history: None
Others: What illness is this? I suspect it's a stomach issue. Could it be related to the fetus?

Doctor's answer:

According to the situation you mentioned, if the vomiting is caused by pregnancy, it is likely due to prolonged vomiting leading to gastric mucosal damage and subsequent bleeding. As long as it is not a large amount of blood being vomited, it should not be a serious issue. First, this situation requires a visit to the hospital for an electrolyte test, as severe vomiting may lead to electrolyte and acid-base imbalance. It is best to get checked. Then, through intravenous fluids and supplements such as vitamins and amino acids, the pregnancy-induced vomiting can be controlled. I hope my answer helps you.
