Does coffee affect kidneys?

Recently, coffee has become more popular than ever. This is the key reason why there's intense research on coffee with respect to health effects. There are a number of research initiatives designed to analyze the impacts of coffee on the immune system, the risk of cancer, and heart disease.

There have been various studies carried out after coffee was discovered to show if it's good or bad for your health. In the recent past, some countries banned coffee consumption due to religious and health reasons. There are numerous studies that have scientifically proven that there are significant health benefits of coffee.

A recent study has shown that drinking coffee can be beneficial because it can lower the risk of kidney illness and increased kidney function. Below is a comprehensive guide on coffee consumption in relation to kidney disease.

Studies such as population-based epidemiological have analyzed the relation between consumption of coffee and its impacts on kidney function.

Studies show that there's no association between kidney illnesses and coffee consumption, especially in male patients. However, this research showed that there's a reduced risk of kidney illnesses in women who tend to drink coffee on a regular basis. This research clearly showed that there's no harm to coffee consumption on males, and it's more beneficial to females.

Recently, a meta-analysis showed that there's a lower risk of chronic kidney disease in coffee-growing villages. This subject is broad, and there are numerous studies that are underway to analyze the topic to the end. Coffee consumption has an antidiabetic effect due to the presence of antioxidants in the beverage.

Below is a comprehensive guide explaining whether coffee can damage kidney:

1. Impact on Kidney Stones patients

There are certain situations where moderating coffee intake may apply. One of these situations is patients who form kidney stones. The common cause of kidney stones is oxalate stones, which are a result of a regular coffee diet. Therefore, if you have kidney stones, it's a great idea to regard coffee consumption as a risk factor due to the presence of calcium oxalate stones.

2. Effect on Genetic Kidney Disease

A study carried out in the past shows that caffeine in coffee can increase the risk of growth of kidney cysts, especially in patients with PKD (autosomal dominant polycystic kidney disease). Recently, due to advanced technology, there's no risk factor for polycystic kidney disease accompanied by coffee intake.

3. Can result in Kidney Cancer

This is an incomplete research topic due to mixed evidence in the studies carried out. Some studies have indicated that consumption of coffee minimizes the risk of renal cell carcinoma. These only apply to caffeinated coffee. The same research showed that decaffeinated coffee increases the risk of renal cell carcinoma subtype. This is a certain kind of kidney cancer, but there are numerous studies to ascertain this link.

4. Renal Failure and Caffeine

Caffeine in coffee can worsen renal failure. A worse renal failure can be achieved if there's a combination of metabolic syndrome and kidney disease. A study was carried out on diabetic rats; this study clearly showed that the introduction of caffeine caused an increased heart rate and protein in the urine. Also, the rats' arteries became less flexible, especially in the kidney. This caused high blood pressure.

5. Diuretic effect

Caffeine is typically categorized under a class of substances termed as methylxanthines, which is a mild diuretic. Caffeine is a form of diuretic substance that acts on a kidney by controlling the absorption of water. A recent study carried out shows that individuals who have not been taking caffeine are likely to increase their urinary output after taking three cups of coffee.

6. Impact on Fluid Balance

Large doses of caffeine found in coffee can lead to increased urine output, particularly when taken in a short duration of time. This effect diminishes, especially if you usually consume coffee regularly. Recent research concluded that there's no link between caffeinated beverages such as coffee with fluid balance.

Indirect Impacts of Caffeinated Coffee on Kidney Function

The leading cause of kidney disease is high blood pressure. Studies give limited evidence that consumption of caffeinated coffee can lead to an increase in blood pressure for a short duration of time. This condition can be more intense if you don't drink coffee on a regular basis. In addition, individuals who have a history of high blood pressure are likely to experience increased blood pressure after drinking this beverage.

Provided you have enough knowledge on the link between high blood pressure and coffee intake, then you'll need a comprehensive guide about coffee's ability to destroy your kidneys. Studies show that if you are not drinking more than four cups of coffee in a day, there will be a reduced risk of suffering from kidney disease, especially for young subjects.

Hypertension and Decaffeinated Coffee

The caffeine content in coffee increases not only your blood pressure but also nervous system activity. This clearly suggests that there might be something else rather than caffeine in coffee that leads to high blood pressure.

The existing weight on this topic clearly shows that consumption of coffee increases blood pressure, especially on individuals with pre-existing hypertension and non-habitual drinkers. However, this doesn't show that coffee consumption leads to an increased risk of suffering from kidney diseases.

To be on the safe range, it's essential to consume not more than three cups of coffee on a regular basis. According to certain research, high consumption of caffeine found in coffee can lower your risk of dying if you're struggling with kidney diseases.

Coffee has a positive hemodynamic impact on cardiovascular health. Low blood pressure will lead to lower glomerular pressure. In addition, coffee contains various compounds with anti-inflammatory and antioxidant impacts.

Chronic kidney disease is categorized among the leading causes of mortality and morbidity in the entire world. There are limited and scarce measures for both treating and preventing this condition. Recently, this condition has been increasing the health care costs at a large margin.
