Cold weather reduces fluid intake, raising kidney stone risk and causing severe pain known as renal colic.
Cold weather and hydration
Cold weather can lead to reduced fluid intake without individuals being aware of it. This reflex can contribute to the formation of kidney stones and trigger renal colic.Expert warns about kidney stones
Dr. Gérald Kierzek, an emergency physician and Medical Director at Doctissimo, warns that the lack of hydration promotes the formation of kidney stones, the main cause of renal colic. In autumn, people often drink less, which increases urine concentration and facilitates the occurrence of crises, even outside of warm periods.Mechanism of renal colic
The mechanism and main causes involve a mechanical phenomenon: renal colic is almost always caused by a kidney stone that suddenly blocks the flow of urine, causing intense pain. This pain is among the strongest known in emergency medicine.Risk factors and lifestyle
The problem often occurs in people who are not sufficiently hydrated. The risk is increased when urine is concentrated, therefore in cases of insufficient water intake, during travel, sedentary lifestyle, or in cold seasons where people feel less thirst.Diet and other factors
However, lack of water is not the only culprit. Dr. Kierzek emphasizes the role of lifestyle and diet, noting that dietary factors, such as excess of certain substances, can contribute to the issue.
