Noticing blood in your stool along with swelling in the upper abdomen, even without pain, is concerning and should be evaluated promptly by a doctor. These symptoms could indicate several conditions, including gastrointestinal bleeding, liver or pancreatic issues, or other abdominal organ problems.

• It is important to see a gastroenterologist or a general physician as soon as possible for a thorough examination.
• They may recommend diagnostic tests such as blood work, abdominal ultrasound, or endoscopy to identify the cause.
• Avoid self-medicating and monitor for any new symptoms like pain, fever, dizziness, or increased swelling.
• If you experience severe bleeding, weakness, fainting, or worsening swelling, seek emergency care immediately.
