The Claim

Postoperative oral carbohydrate intake in patients undergoing knee arthroplasty is associated with significantly lower hunger and anxiety levels at 6 hours after surgery compared to ingestion of plain water.

In plain English

Patients who drink a carbohydrate solution after knee surgery report lower hunger and anxiety at 6 hours post-operation than those who drink only water.

See the scientific wording

Postoperative oral carbohydrate intake in knee arthroplasty patients is associated with significantly lower hunger and anxiety levels at 6 hours after surgery compared to plain water, suggesting a psychological and physiological benefit during early recovery.

Why this might work

Eating a sugary drink after surgery quickly raises blood sugar, which tells the stomach to stop sending hunger signals and tells the brain to make more serotonin, a chemical that calms anxiety. This stops the stress response and makes the person feel less hungry and less nervous.
