What are the 3 early warning signs of kidney disease?

If you have kidney disease, you may not have any symptoms in the early stages. That’s why regular check-ups are often recommended. But there are three early warning signs of kidney disease that you should be aware of:

  1. Fatigue
  2. High levels of protein in your urine
  3. Swelling in your ankles, feet, or legs

If you notice any of these symptoms, make sure to visit your doctor before jumping to any conclusions. Kidney disease is a serious condition, but it can be treated if it’s caught early.


We all love caffeinated drinks, don’t we? It’s understandable as there are several benefits of caffeine. If you’re a regular consumer of energy drinks then you might know that almost every energy drink contains caffeine as a major ingredient.

Caffeine doesn’t only enhance cognition such as memory, focus, and concentration but it also helps to improve physical health – if you’re fatigued, caffeine will make that fatigue go away within a span of a short time.

However, with all these benefits, there are some side effects of caffeine as well. Caffeine can increase the overall stress on the body.

Being a stimulant, it has the power to increase the levels of adrenaline and cortisol in the body which can make increase your blood pressure and can also affect your heart, kidneys, brain, and other important organs of the body.

Is caffeine bad for the kidney?

Everyone is aware that caffeine is an effective psychoactive drug. It’s a stimulant that can help us get through the day by keeping us alert. However, did you realize that consuming too much coffee might be harmful to your health?

Your kidneys may experience side effects from caffeine as the blood flow, blood pressure, and renal pressure increase. In some extreme cases, kidney stones can be a side effect too.

But don’t worry, this isn’t always the case. It happens only when you consume caffeine in an excessive manner. To avoid these side effects, aim to keep your daily caffeine intake to no more than 400 mg.

Can Red Bull make your kidneys hurt?

Red Bull
Red Bull has sugar and caffeine. However, the drink has a variant that is sugar-free.

Red Bull energy drink contains sugar and caffeine. Both these ingredients are linked with kidney diseases.

A high-sugar diet and caffeine diet can put stress on your kidneys. Both of these ingredients are stimulants and both of these ingredients in high quantities are linked with dehydration.

Are sugar-free energy drinks bad for your kidneys?

Sugar-free energy drinks are less likely to be bad for your kidneys than energy drinks with sugar. But if it contains high caffeine then it may be bad.

Sugar is also a danger to your kidneys, especially in large amounts. Sugar can cause an increase in your blood sugar levels which can lead to kidney disease. This is why I suggest energy drinks with moderate amounts of caffeine and little to no sugar in them.
