What Causes Swollen Stomach, Severe Abdominal Pain And Bleeding From Rectum?
Colonoscopy should be done.
Detailed Answer:
Hello!
Thank you for the query.
Such symptoms at her age (over 50) can indicate colon cancer or inflammatory bowels disease. Especially if the blood is mixed with the stool (not on its surface), she has lost some weight recently, has bloating, cramps, nausea.
Weakness and collapse history can be due to dehydration or anemia or both. Back pain can be present due to kidneys infection which can appear due to dehydration.
She definitely should have diagnostic done. Blood work, urine analysis, abdominal CT (or ultrasound) and most important - colonoscopy should be done to find out the reason. She should not wait with it.
Hope this will help. Feel free to ask further questions.
Regards.
