Ever noticed how sometimes your body gives you “hints” that something deeper is going on? For instance, when your eyes swell up like tiny balloons in the morning, or when your vision unexpectedly starts playing "hide and seek"? But you might be surprised to find out it is most likely due to your kidneys!
Yes, those bean-like organs that sit in your lower back are secretly your eyes' BFFs. So, when the kidneys start to shut down or struggle, your vision may be affected as well. So, let’s dive into the topic of vision problems with kidney failure in detail.
You might be thinking to yourself: What on earth do the kidneys have to do with eyesight? They're in different neighborhoods of your body! However, both organs have one element in common: They both rely on small, delicate blood vessels to do a lot of work. The kidneys filter the blood that goes through small blood vessels known as nephrons. The eye, specifically the retina, depends on small blood vessels that provide oxygen and nutrients to keep vision sharp.
Damaged kidneys, whether from chronic kidney disease (CKD) or from kidney failure, can not only affect blood flow to the kidneys; this blood flow can also be impacted in the blood vessels of your eyes. This can lead to blurry vision, swelling, or other more serious conditions like retinopathy, which indicates damage to your retina.
Think of it like this: if your kidney’s plumbing system starts leaking, your eye’s electrical system starts flickering too!
If you have a kidney disease, then you may experience the following eye-related symptoms:
Blurred vision
Dry eyes
Puffy eyelids
Eye floaters
Sensitivity to light
Swelling around eyes (especially in the morning)
Eye fatigue
Mild eye redness
Yes, it does. Damaged kidneys can hinder the blood flow towards the eyes, leading to blurry vision and other eye issues. Let’s break down the kidney vision problems in further detail:
You know that fuzzy feeling when your glasses are smudged? That’s kind of what happens when kidney failure causes fluid imbalance in your body. Too much fluid retention can affect the lenses of your eyes, changing their shape temporarily and making your vision blurry. It is one of the biggest vision problems with kidney failure.
This is the big one and is one of the major vision problems with kidney failure, especially for people with diabetes or high blood pressure, which are also leading causes of kidney failure.
In diabetic retinopathy, the small blood vessels in your retina are damaged by high sugar levels. These vessels leak blood or fluid, which distorts your vision, creates dark spots, or could lead to blindness if left untreated.
If you wake up as if you lost a boxing match (without fighting anyone), it could be your kidneys. Poor kidney function can lead to fluid retention, resulting in swollen or puffy eyelids or bags under your eyes.
Kidney disease can also cause disruptions in the production of tears, leading to dry, itchy eyes, similar to if you’d been glued to your phone for 12 hours (sorry!).
This rare but serious condition occurs if a toxin from the kidney or high blood pressure damages the optic nerve. Consequently, you may experience sudden vision loss; this is not typically on anyone’s wish list.
Here’s where it gets more interesting (and slightly ironic). The same conditions that cause kidney failure, namely diabetes and high blood pressure, are also the top culprits behind eye problems.
So, if your kidneys are acting up, there’s a good chance your eyes might be affected too.
It’s like a buddy system gone wrong: “If I go down, you’re coming with me!”
High blood pressure can cause the retinal blood vessels to narrow or leak.
High blood sugar makes those vessels weak and prone to rupture.
Over time, both can reduce oxygen to your retina, which your eyes don’t appreciate one bit.
Now let’s look at this through the calm and ancient lens of Ayurveda, which believes that every organ in your body is connected through the balance of three doshas: Vata, Pitta, and Kapha.
• Alochaka Pitta governs the eyes. Alochaka Pitta allows and governs clarity of vision and perception of light.
• Apana Vata and Kapha govern the kidneys. Apana Vata and Kapha govern and control water balance and elimination.
Both the eyes and kidneys will experience imbalance when your doshas are out of balance (due to poor diet, stress, or illness). This is why Ayurvedic well-being is concerned with naturally detoxifying, strengthening, and balancing rather than simply addressing the symptoms.
• Punarnava– helpful to reduce swelling and fluid retention.
• Triphala- encourages clarity of vision and gentle detox.
• Guduchi (Giloy)- suitably boosts immunity and reduces inflammation.
• Amla – high in Vitamin C, encourages healthy vision and rejuvenates the kidneys.
(Of course, don’t start munching herbs on your own; always talk to an Ayurvedic doctor first!)
Control Blood Sugar & Pressure:
The golden rule. Keep both in check, and you’ll protect your eyes and kidneys at the same time.
Stay Hydrated (But wisely):
Aim for 8-10 glasses of fluids, but first consult a doctor.
Eat a Kidney-Friendly Diet:
Consume fresh fruits, vegetables, and whole grains. You must avoid salty snacks and processed foods.
Avoid Smoking & Alcohol:
Both these habits damage your renal cells over time.
Regular Eye Check-ups:
If you have CKD or are on dialysis, make sure you go for an eye checkup every six months.
Your kidneys and eyes are like two compatible roommates sharing the same Wi-Fi (your blood vessels). When one is disconnected from the Wi-Fi, the other starts buffering! If you are ever seeing visual changes, have swelling or eye strain, don’t dismiss this as “just tiredness.” This may be a way your kidneys are getting your attention!
If you are maintaining balanced blood sugar, controlled blood pressure, and an Ayurvedic lifestyle, you will keep both your vision and kidneys at ease. After all, the best gift is being able to clearly see the world (literally!)
Yes, when kidneys don’t filter toxins properly, it can lead to high blood pressure, fluid retention, and damage to the retina, affecting vision.
