Dizziness

Long-term dizziness after cancer treatment can stem from late-effect nerve damage, inner ear injury from specific medications like platinum-based chemotherapy, prior radiation near the brain or ear, persistent anaemia, cardiovascular shifts, or ongoing general physical deconditioning.

Common Long-Term Causes

• Ototoxicity (Inner Ear Damage): Certain past chemotherapy drugs (such as cisplatin or carboplatin) or cranial radiation can permanently injure the inner ear structures or vestibular system, leading to chronic imbalance or vertigo
• Persistent Anaemia: Low red blood cell counts reduce oxygen delivery to the brain, which can become a chronic issue causing ongoing light-headedness and fatigue
• Late Cardiovascular Effects: Radiation to the chest or certain targeted therapies can impact heart function or blood pressure regulation, resulting in orthostatic hypotension (dizziness when standing)
• Neuropathy: Peripheral nerve changes from past treatments can impair sensory feedback to the brain, disrupting normal balance
• Deconditioning: Extended inactivity or muscle loss during and after heavy treatments can leave the body prone to weakness and dizziness upon movement

Please see your GP if you are experiencing dizziness
