What two conditions are concerning if tachycardia occurs after bariatric surgery?

Tachycardia after bariatric surgery can be an indicator of serious complications, particularly anastomotic leak and pulmonary embolism. An anastomotic leak occurs when there is a breakdown in the connection between two segments of the gastrointestinal tract following the surgical procedure. This condition can lead to peritonitis, sepsis, or significant fluid loss, all of which can provoke a tachycardic response as the body tries to compensate for the stress and potential hypovolemia.

Similarly, a pulmonary embolism (PE) is a blockage in one of the pulmonary arteries in the lungs, usually caused by blood clots that travel to the lungs from the legs or other parts of the body (deep vein thrombosis). After bariatric surgery, patients are at risk for thromboembolic events due to factors such as immobility, changes in body weight and blood flow, and the surgical procedure itself. PE can present with tachycardia as the heart rate increases in response to decreased oxygenation and the body's need to maintain cardiac output.

Both anastomotic leaks and pulmonary embolisms are critical conditions that require immediate medical attention, making the occurrence of tachycardia significant within this context. Understanding these associations is vital
