With the question "What disease is red blood in the urine?" , the doctor would like to answer as follows:
Manifestations of blood in the stool are dark red, suspecting gastrointestinal bleeding. You need to go to the doctor right away to do the necessary tests such as blood tests, ultrasound, endoscopy, ... to find the cause of the bleeding and the appropriate treatment.
If you still have questions about passing dark red blood, you can go to a hospital under Vinmec Health System for further examination and advice. Thank you for trusting and sending questions to Vinmec. Wish you a lot of health.
