Is Coffee Bad for Kidney Health?

Is Coffee Bad for Kidney Health?

Caffeine is a natural drug found in many plants, but many companies can also produce it artificially. Science considers caffeine a drug because it tends to stimulate the nervous system and stresses the kidney. This drug is used for different beverages, food, and supplements.

The caffeine included in every beverage varies depending on the plant that produces it. Some of the beverages include coffee, tea, soda, cocoa, and energy drinks. However, coffee is the most popular among the others. Since caffeine is considered a drug, is coffee bad for kidney health?

Is Coffee Bad for Kidney Health?

Coffee is one of the most common caffeinated beverages worldwide. Due to its popularity, drinking coffee has become a daily habit of many adults, regardless of age and gender. However, a lot of studies talk about the good and bad effects of coffee on general health, including kidney health.

Most of the studies conclude that consumption of coffee is not risky for kidney health if it does not exceed the suggested number of cups.

The results show that coffee is beneficial for the kidney as it can help slow the progression of Chronic Kidney Disease (CKD). These studies also include that coffee decreases the risk of developing End-Stage Kidney Disease (ESKD) and albuminuria, a sign of kidney disease where protein releases into the urine.

Coffee may not be harmful, but the additives can increase the risk of harming the kidneys. The most common additives are milk and creamers. These two can increase the content of potassium and phosphorus in the coffee.

Thus, people with kidney disease might need to see a kidney dietitian to have a more appropriate diet plan.

Effects of Caffeinated Beverages on Kidney Health

Caffeine beverages have their limitations when it comes to their benefits to kidney health.

These beverages include coffee, tea, soda, chocolate, and energy drinks. Too much consumption of caffeine can also lead to other kidney-related problems.

Some of these are the following:

  • Hyperkalemia. Coffee contributes to high potassium levels in the body. If you have kidney disease, your kidney will be unable to fill out unnecessary potassium and may eventually stay in the blood, a dangerous complication.
  • Increase blood pressure. It is a mild condition that may only happen in a short time after drinking one cup. The primary cause is unclear, but some studies conclude that caffeine blocks the hormone that widens arteries.
  • Kidney Stones. Caffeine may reduce the risk of the formation of kidney stones, but not all of its types. Caffeinated sodas increase the risk of occurrence and recurrence of kidney stones. Some study results conclude that the sugar included contributes to the increase in the risk of kidney stones formation. Moreover, drinking coffee and black tea can also be a risk factor in forming calcium oxalate stones in the kidneys.

Effects of Caffeinated Beverages on Urological Health

Moderate consumption of caffeine is considered safe and beneficial. However, many people tend to indulge in excessive consumption that may lead to these problems.

  • Increase in urine volume. Caffeine is a diuretic, which means it stimulates urine production by changing the way the kidney handles sodium, thereby causing it to expel excess water or urine.
  • Urinary incontinence. A medical school conducted a study involving men consuming caffeine by drinking two cups of coffee every day. The result shows that moderate to severe incontinence may occur by consuming too much caffeine, as it also gives laxative effects on the bowel.
  • Bladder irritation. People with urinary tract problems may experience bladder pain and bladder inflammation. These conditions happen due to caffeinated drinks. However, these drinks are hard to remove from the diet. Physicians may advise to stop for one week and see the improvement of the symptoms. Then, gradually return to consuming one to two cups every week.

Key Takeaways

Caffeine is a potentially addictive substance that can be found in many foods and beverages. One of these beverages includes coffee. However, is coffee bad for kidney health?

It is proven beneficial to kidney health but not in urological health. Too much consumption may help decrease the risk of worsening kidney disease, but it can lead to problems in urological health.

Low to moderate consumption of caffeine is usually suggested. For more accurate and healthy consumption, consult your healthcare provider if you have kidney problems.
