The Claim
In adults aged 75 and older, intracellular water content per kilogram of lean mass is inversely associated with the number of chronic medications and comorbidities.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In adults aged 75 and older, higher numbers of chronic medications and health conditions are linked to lower levels of water inside cells relative to lean body mass.
See the scientific wording
In adults aged 75 and older, intracellular water content per kilogram of lean mass is inversely associated with the number of chronic medications and comorbidities, suggesting that polypharmacy and multimorbidity may contribute to cellular dehydration.
As people age, their kidneys become less able to concentrate urine, causing the blood to become more concentrated. This pulls water out of muscle cells, making them shrink. Dry muscle cells trigger inflammation and activate a system that breaks down muscle proteins, weakening the muscles even if their size doesn't change.
What the research says
1 studyOlder adults with more water inside their muscle cells tend to be stronger and less frail, and this water level goes down as they get sicker — suggesting that being sick or taking many meds might dry out cells.
