Why do I vomit and pass black stools after meals?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I vomit after eating and have an upset stomach, too. I also have a black stool.

What could be the causes of these?

Please help.

Thank you.

Answered by Dr. Ajeet Kumar

Hello,

Welcome to icliniq.com.

This seems to be a peptic ulcer in the stomach. The pain of a stomach ulcer worsens after eating meals. Do you have a previous history of peptic ulcers? The black stools are suggestive of ongoing bleeding from a peptic ulcer; the bleeding may be small to cause a change in the color of stools; however, a large ongoing bleeding can not be ruled out unless I know your blood pressure and heart rate. Plus, do you have vomiting of a similar black color these days?

I suggest you start capsule Esmoperazole 40 mg (proton pump inhibitor) twice daily before meals. Take this medication regularly. In case you are feeling faint, or dizzy, blurred vision when you stand from a sitting position, or your upper level of blood pressure (systolic blood pressure) is less than 90, or your heart rate is above 90 beats per minute, I recommend you visit the nearby emergency department for treatment and possible need for an endoscopy. Otherwise, if you do not have any alarming signs, as I mentioned, I suggest you start medications and see if it helps you. This medication will suppress the acid production in the stomach and will help heal the ulcers in the stomach. Let me know if I can provide more information about your condition. Take care.
