Welcome to HealthcareMagic
black tarry stools means denatured blood and this is due to gastritis or duodenitis which is due to H pylori ..please see that h pylori treatment will be given for a few days .continue tab omeprazole 20 mg two times atleast for 2 months ..with time your bleed will stop and your stool will regain normal colour .
If you have any further query then you can come back to HealthcareMagic i will definitely help you and guide you appropriately .
