A 2008 study of South Korea with more than 2,600 women showed that coffee consumption is associated with a reduced risk of kidney disease even in women with diabetes.
However, in medicine, investigations rely on population is insufficient to draw definitive conclusions.
Given the potentially controversial nature of this topic an analytical study published in 2016 attempted to answer this question.
This analysis shows: There is no association between coffee consumption and increased risk of kidney disease in men, but interestingly, coffee consumption has the ability to reduce the risk of kidney disease. kidney disease in women if used in moderate doses.
The results of the above analysis were similar to another study on the Pacific coast of Nicaragua where the rate of Lower prevalence of chronic kidney disease in coffee-growing villages has been documented.
The exact mechanism of coffee’s renoprotective effect remains to be studied further, but the The initial explanation given was due to the role of antioxidants in coffee along with the anti-diabetic effects of coffee.
According to recommendations, a normal person can drink about 250- 400mg of caffeine (equivalent to 2-3 cups) a day.

The reason coffee can increase heart rate and breathing can cause irritation in the digestive tract, nausea, stomach pain... or increase intestinal motility.
Effects of coffee on for people with hereditary kidney disease
In the past, basic science studies have shown that caffeine may increase the risk of developing kidney cysts in patients with kidney disease. polycystic kidney disease. However, in many current clinical studies, coffee consumption is not considered a risk factor for the progression of polycystic kidney disease.

Coffee has been proven to have can increase nervous system activity as well as blood pressure even without caffeine. Therefore, when drinking coffee without caffeine, blood pressure can still increase, leading to the hypothesis that there may be other substances in coffee. Coffee is responsible for increased blood pressure.
However, there is data showing that if you drink coffee daily, do not exceed 3-4 cups (with each 200ml cup containing 100-200mg of caffeine). There will be no increased risk of kidney disease in otherwise healthy young people.
