Climate change could spark a rise in KIDNEY STONES: Higher temperatures caused by greenhouse gases will lead to an increase (?)
This is just modelling, which proves nothing. A hot climate actually is associated with more kidney stones but the tiny rise in average temperature of recent times is unlikely to be the cause behind the recent increased incidence. Many other factors can affect the incidence of the stones
More hot days in the future will likely due to greater water losses through sweat, resulting in more concentrated urine and increased formation of kidney stones, researchers in Pennsylvania claim.
Kidney stones are hard deposits made of minerals and salts that form inside your kidneys.
They form when your urine contains more crystal-forming substances – such as calcium, oxalate and uric acid – than the fluid in your urine can dilute.
Previous research has already shown that high ambient temperatures increase the risk of developing these kidney stones.
Not drinking enough water contributes to their formation because more water in the kidneys helps prevent stone-forming crystals from sticking together.
Higher temperatures are therefore more likely to cause dehydration, which in turn leads to the painful condition, which can often require surgery.
The new study was conducted by researchers at Children's Hospital of Philadelphia (CHOP) in Pennsylvania, led by urologist Dr Gregory E. Tasian.
'It is impossible to predict with certainty how future policies will slow or hasten greenhouse gas emission and anthropogenic climate change, and to know exactly what future daily temperatures will be,' Dr Tasian said.
'[But] our analysis suggests that a warming planet will likely cause an increased burden of kidney stone disease on healthcare systems.'
In the US, there is an increase in the incidence of kidney stones from North to South, and there is a rapid increase in risk of kidney stone presentations following hot days.
However, previous studies have not precisely projected how climate change will impact the burden of kidney stone disease in the future.
A study by the Mayo Clinic found an overall increase in the prevalence of kidney stones across three decades.
The rate of confirmed symptomatic stones increased more than 300 per cent in women and 100 percent in men from 1984 to 2012.
While the increase can in part be explained by improvements in medical imaging technology, experts said it could also be linked to the dietary factors driving increases in cancer, heart disease, diabetes and obesity.
