Eye Symptoms of Kidney Problems: The eyes can reveal what's wrong with the human body. Let us explain how you can tell from your eyes if your kidneys are about to be damaged.

Symptoms of kidney failure

Kidney Disease Warning Signs: People often associate kidney disease with fatigue, swelling in the legs, or changes in urine, but sometimes it starts in the eyes. This is because both the kidneys and eyes depend on the body's small vessels and fluid balance. When the kidneys don't function properly, the effects are visible on the eyes as well. Persistent swelling, blurred vision, redness, irritation, or changes in color perception can all point to a deeper problem. These changes are initially mild, but can worsen over time. If these symptoms appear along with fatigue or swelling, it's important to get both the kidneys and eyes checked. Let us explain this in detail.

Kidney disease first shows its effect on the eyes.

Most people believe that kidney disease is only detected by fatigue, swelling, or changes in urine, but the truth is that its early signs can also be visible in the eyes. According to the National Kidney Foundation, the kidneys are the body's filtering system, and the eyes rely on extremely delicate blood vessels. As kidney problems affect fluid balance or blood vessels, changes in the eyes become immediately noticeable. As kidney problems progress, vision, eye moisture, optic nerves, and even color perception can be affected. Sometimes, these symptoms mimic a common eye condition, leading to delays in identifying the real problem. If ignored, these symptoms worsen. Here are five eye-related symptoms that, if ignored, can lead to serious complications:

Persistent swelling in the eyes

Sometimes, staying up late or eating too much salt can cause puffy eyes. However, if the swelling persists throughout the day, it could be a sign of protein leakage from the kidneys. When the kidneys are unable to filter protein, it is excreted in the urine, resulting in swelling around the eyes. If the swelling is accompanied by frothy or excessively foamy urine, consult a doctor immediately.

blurred or double vision

Sudden blurred vision or double vision can be a sign of damage to the small retinal veins. High blood pressure and diabetes, two of the most common causes of kidney failure, also damage the retinal veins. Fluid accumulation, retinal swelling, or, in severe cases, vision loss can occur. If you are diabetic or have BP and notice changes in your vision, kidney function testing is also necessary.

Dryness, burning, or irritation in the eyes

Frequent dryness or stinging of the eyes isn't just a result of the weather or screen time. Dry eyes are a common complaint in patients with advanced kidney disease or those receiving dialysis. Calcium-phosphorus imbalances or toxin accumulation can lead to reduced tear production. If the eyes remain red, dry, or sting without reason, it's important to get a kidney checkup.
