Furthermore, the risk of dehydration increases as we age. This is in partly due to water cells bring compromised as we age.
Some sources share that people with PD drink 50% less than people without PD due to difficulty with swallowing, medication side effects, motor impairments making using the bathroom tricky, and the lack of thirst sensation.
Dehydration can lead to poor blood flow, higher blood pressure, and in worse cases, organ failure.
