Bleeding after exercise from any part of the body is a rare event and needs medical followup.
Normal Exercise Physiology
During exercise, humans experience a five-fold increase in blood flow. Some organs become engorged with blood but do not bleed unless there is a break in a blood vessel. Bleeding after exercise is rare.
Which Organs Can Bleed After Exercise?
Bleeding in the urine, or hematuria, after exercise is usually not serious, but needs attention from a urologist. Coughing up blood after exercise can be a sign of heart or lung disease and requires prompt attention. Nose bleeding, or epistaxis, can occur after exercise with blood disorders and requires an ear, nose and throat specialist. Eye, ear, rectal, skin and vaginal bleeding after exercise are extremely rare and should prompt quick medical consultation.
What Would Cause an Organ to Bleed?
The causes of bleeding come down to things that injure blood vessels, such as
cancer, infection or inflammation. In addition, bleeding disorders may cause
blood vessels to ooze after exercise. All of these require medical attention.
What Should You Do If This Happens?
Seek medical care within days if you have no other symptoms. If you have pain, fever or shortness of breath with bleeding, then you should go to the emergency room.
