A look at some of the hypothesised Mozart's death cause
The lack of the exact cause of his premature death has been the subject of extensive speculation. Here is a detailed breakdown of some of the hypothesised Mozart's causes of death:
Kidney Disease
Chronic kidney disease leading to uremia has been suggested as a likely cause. Mozart's symptoms, including swelling, vomiting, and fever, align with this diagnosis.
Streptococcal Infection
A retrospective epidemiological study proposed that Mozart suffered from a streptococcal infection. This might have progressed to acute nephritic syndrome, causing kidney failure.
Schönlein-Henoch Purpura
Some researchers believe he had Schönlein-Henoch purpura, a condition involving kidney damage, abdominal pain, and rashes, which may have led to cerebral haemorrhage and bronchopneumonia.
Rheumatic Fever
Rheumatic fever has been frequently mentioned as a possible cause due to its prevalence in Vienna at the time and its compatibility with his symptoms.
Vitamin D Deficiency
A theory suggests that Mozart's nocturnal habits and limited sunlight exposure caused vitamin D deficiency, weakening his immune system and making him susceptible to infections.
