Caffeine is a bitter, white crystalline xanthine alkaloid that acts as
a stimulant drug. Caffeine is found in varying quantities in the seeds, leaves,
and fruit of some plants, where it acts as a natural pesticide that paralyzes
and kills certain insects feeding on the plants
A caffeine intake equivalent to just two cups of coffee per day (250 mg) was
associated with increased prevalence of moderate-to-severe kidney disease in an
analysis of 3960 men who participated in a American studies on diet for patients
with kidney disease. Although caffeine reduction is now part of recommended
lifestyle interventions for women, few studies have explored the association
between caffeine and kidney disease in men, say the doctors, who suggest that
the effects of caffeine reduction in men with kidney disease should also be
evaluated.
The US National Institutes of Health states "too much caffeine can make you
restless, anxious, and irritable. It may also keep you from sleeping well and
cause headaches, abnormal heart rhythms, or other problems. If you stop using
caffeine, you could get withdrawal symptoms. Some people are more sensitive to
the effects of caffeine than others. They should limit their use of caffeine. So
should pregnant and nursing women."
In a word, it is not good for patients with kidney disease to dink so much
caffeine.This is why people with Kidney Disease is suggested to avoid drinking coffee. Good News is that there are alternative drinks to coffee for kidney disease patients to choose. If you have a interest, you can email to kidneyask@hotmail.com to get the list.
