Does gastric bypass surgery cause bruises?

Gastric bypass surgery itself does not typically cause bruising directly; however, some patients may experience bruising around the incision sites due to the surgical procedure. Bruising can occur as a result of surgical trauma or the use of blood-thinning medications during or after the surgery. It's important for patients to follow post-operative care instructions and report any unusual or excessive bruising to their healthcare provider. Overall, slight bruising can be a normal part of the healing process.
