I had black stools, but no blood, no pain in the epigastrium. So the doctor asked me to pass black stools, is there stomach bleeding?

The three children are 57 years old this year. Dad was admitted to the hospital with the reason of vomiting blood and passing black stools.

So the doctor asked me how to treat patients with stomach bleeding due to ulcers? How to take care of three children? I thank you doctor.

About 2 weeks now, I have a dull pain in the abdomen below the navel accompanied by defecation, constipation, black stools (black stools) and farting a lot for more than 1 day, with a very bad smell and discomfort. So the doctor asked me if I had a dull pain in the lower abdomen with bowel disorders? I thank you doctor.

My husband had a stomach ache to have a bowel movement, but when he had a bowel movement, oil scum floated on the dark brown water. So the doctor asked me if my stomach ache comes out with black brown oil scum, what is the sign of the disease? Treatment like? Thank you.
