what kind of illness did elizabeth barrett browning have?

Elizabeth Barrett Browning lived with a lifelong, chronic illness that significantly affected her daily life, starting in early adolescence. Contemporary medical historians and physicians have proposed several possible diagnoses, but no single, definitive cause has been established. The illness was characterized by persistent pain, weakness, and episodes of paralysis or severe muscular spasms, along with episodes of heart palpitations and susceptibility to temperature extremes. Over time she also developed respiratory problems, including lung-related issues, which were commonly attributed to tuberculosis in her era. However, modern interpretations have suggested alternatives such as a form of chronic neuromuscular or autonomic dysfunction, hypokalemic periodic paralysis, or other chronic illnesses that can cause widespread pain and fatigue. The exact nature remains uncertain because the medical vocabulary and diagnostic frameworks of the 19th century offered many competing explanations, and Browning’s own extensive journals indicate a lifelong struggle with debility rather than a clearly defined singular disease. In short, she suffered from a persistent, poorly diagnosed chronic illness with a spectrum of symptoms including severe pain, weakness, intermittent paralysis-like episodes, and respiratory concerns, rather than a clearly pinpointed modern diagnosis.
