More details

Connecting gastrointestinal bleeding to your symptoms

Vomiting blood or black sticky stools are not symptoms to be recorded while waiting

Vomiting that looks like coffee grounds and black tarry stools can occur from upper gastrointestinal bleeding. Significant bright red bloody stools also require prompt evaluation. If combined with dizziness, cold sweats, shortness of breath, or throbbing, emergency room care takes priority over a Korean medicine clinic appointment.

Do not assume it is due to hemorrhoids or food based on color alone

Iron supplements and certain foods can make stools black, and bright red blood on toilet paper can originate from areas close to the anus. However, if this recurs, is mixed into the stool, or is accompanied by abdominal pain or weight loss, the cause must be identified. Please also inform medical staff if you are taking NSAIDs or anticoagulants.

If bleeding is suspected, safe transport takes priority over measuring the amount

If vomiting blood, black sticky stools, or significant bright red bloody stools occur along with dizziness, cold sweats, and shortness of breath, do not drive yourself and seek emergency help immediately. If possible, show photos of the stool or vomit and a list of anticoagulants or NSAIDs to the medical staff. Even if symptoms have stopped, do not delay identifying the cause of the bleeding.

Frequently Asked Questions

Frequently asked questions regarding gastrointestinal bleeding

Is a small amount of blood on toilet paper also gastrointestinal bleeding?

It can be caused by wounds near the anus or hemorrhoids, but it cannot be determined by color and amount alone. If it recurs, is mixed into the stool, or is accompanied by abdominal pain or weight loss, seek medical evaluation.

Can I receive Korean medicine treatment for indigestion that remains after treatment for bleeding?

After first following the treatment for the cause of the bleeding and the re-examination plan, we can evaluate remaining post-meal fullness, pain, and changes in bowel movements once your condition has stabilized. You must disclose all medications you are taking, including anticoagulants and anti-inflammatory analgesics.
