Jane Austen died on July 18, 1817, at the age of 41 after a prolonged illness lasting about a year. The exact cause of her death remains uncertain, but several hypotheses have been proposed based on her symptoms and historical medical analysis. The most widely discussed possibilities include Addison's disease (a rare disorder of adrenal insufficiency), Hodgkin's lymphoma (a type of cancer), and systemic lupus erythematosus (a chronic autoimmune disease). Other suggestions have included tuberculosis, arsenic poisoning, and some form of cancer. Her official cause of death was recorded vaguely as "consumption" or "decline," and no post-mortem examination was conducted. She died in Winchester, England, with her sister Cassandra by her side after seeking treatment from a surgeon at a local hospital.
