Hi and welcome to HCM!
Thanks for posting your query here.
Vomiting a dark gray color vomit is from the GI tract-called as haematemesis. It is a blood mix with the acid in the stomach which gives you that colour. It is because of a lower oesophageal bleed or a gastric ulcer bleed. If the vomiting doesnt stops it is an acute emergency. You need to run to ER. If it is only one episode omeprazole
or pantaprozole can be used for the time being and consult a Gastroenterologist
. To confirm the lower oesophageal bleed an upper GI endoscopy
is required. Antiemetics like domperidone
can be used to relieve the vomiting. Antispasmodics like dicyclomine
can be used to relieve the spasm. If you are on aspirin please stop taking the medication as it also can cause upper GI bleed.
Hope this is helpful to you
