Patients receiving chemotherapy for other conditions that are not AL amyloidosis are often told to "drink plenty" to avoid dehydration. But in AL amyloidosis, this well-meaning advice is inappropriate and can prove dangerous.
Many patients living with AL amyloidosis have amyloid deposits in the kidneys and/or in the heart. These two problems mean that the body is unable to cope well with excess fluids. The combination of kidneys that are unable to sufficiently clear the fluid into the urine and a heart that is too stiff to pump efficiently may be problematic. If amyloidosis affects just one of these organs, excess fluids can make matters worse.
