Hello,
With the question “What are the signs of nausea, vomiting blood? ", the doctor would like to answer as follows:
Your poor digestion has 2 possibilities: First, because of food, second, your stomach has a problem. Vomiting eventually with fresh blood is likely due to tearing of the Z line (gastroesophageal junction) due to vomiting. For a Z-line tear, it can be self-healed (if the tear is not deep, no major blood vessel damage)
If the place where you go to the hospital is difficult, you can self-monitor at home as long as the amount of vomiting blood little, no nausea and no further vomiting, no dizziness, pink skin and mucous membranes, not rapid pulse. You should rest, eat cold liquids. If there are any abnormal signs (not matching the above conditions, you need to go to the hospital for examination and treatment.
If you still have questions about vomiting blood, you can go to the hospital of the System. Vinmec Health System for further examination and advice Thank you for your trust and question to Vinmec. Wishing you a lot of health
