Hi,
Black stools after stomach bug is a concerns.
Black stools means malena and occurs due to intestinal bleeding or excessive iron contents in the form of iron rich food or Iron containing tablets.
Since you have intestinal problems there is more chance of bleeding in the
esophagus, stomach or
small intestine.
Hence I would advise you the following:
Consult your Doctor for clinical evaluation, examination and investigations of stool and blood.
If there is bleeding then you may need admission to hospital, monitor the vitals, monitor
hemoglobin level and undergo upper and lower GI
Endoscopy.
Also needed is a CT scan of abdomen.
All these will help to find out the possible area of bleeding and get treated accordingly.
You will need intravenous fluids, blood if necessary and antibiotics.
Consult your Doctor or ER immediately.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T Chandrakant,
General Surgeon.
