Bloodletting turned a throat illness into a crisis

The practice was bloodletting: deliberately draining blood in the hope of treating disease. When George Washington became gravely ill in December 1799, his doctors repeatedly removed blood as his throat swelled and his breathing grew difficult. Historical accounts describe several rounds of bleeding over a short period, alongside other treatments that reflected the medicine of the era.

The danger was immediate. Blood carries oxygen to the body’s tissues; losing a large amount can sharply reduce the blood available to keep the heart and brain functioning. A person already struggling to breathe has even less room to withstand that loss. Modern doctors looking back at Washington’s symptoms often suspect a severe throat infection, possibly involving inflammation that narrowed his airway. The exact diagnosis cannot be established with certainty from the surviving descriptions.

Why doctors thought removing blood might help

Eighteenth-century physicians commonly treated illness through the idea that the body’s internal balance had been disturbed. Draining blood was meant to reduce that imbalance and relieve the body’s strain. It was a familiar intervention, not a reckless exception—but familiarity did not make it safe, especially for someone severely ill.

Washington’s condition worsened rapidly, and blood loss likely weakened him further. It is difficult to separate its effect from the underlying illness and the other treatments he received, so no modern diagnosis can prove that bleeding alone caused his death. Still, the episode shows how a standard remedy could become an added threat: as his airway narrowed, his body was also being deprived of blood it needed to sustain its organs.
