7 Early Signs Your Kidneys Might Be in Trouble
Sometimes we get sick and know it right away, but some diseases stay hidden. Have you ever thought about that? Whenever we get sick, we find out quickly because our body starts showing signs.
For example, when we get a fever, our body temperature goes up, and that’s how we know we are sick.
But do you know, there are some diseases that don’t show any signs at all, so we don’t even realize we have them? Our body does give us signals, but we are the ones who ignore them. This ignorance is what sometimes becomes the reason for our death.
Kidney damage is also like that, it happens silently, and we don’t even realize it. I saw this happen in my own family. It happened in 2023 both of my aunt’s kidneys got damaged. The reason was the same: she ignored the symptoms her body was showing. Even though she was taking medicines in the same doses as a healthy person would, because her kidneys weren’t functioning properly, this actually harmed her. That’s why it’s also important to check and calculate the right medicine dose to ensure kidney health.
Nowadays, kidney disease and kidney problems are becoming very common. Therefore, everyone should know what symptoms can show when the kidneys start getting damaged. Knowing the early signs can actually save a life.
Kidney Disease – The Silent Killer
Kidney disease is also called a silent killer. The reason behind it is that it usually doesn’t show clear signs in the beginning.
They can keep working even when they are getting damaged, therefore you may feel completely fine for a long time. By the time symptoms such as tiredness, swelling, or changes in urine appear, a lot of damage has already been done.
That’s why many people don’t know they have kidney disease until it gets very serious. According to the National Kidney Foundation, people with kidney disease may not feel ill or notice symptoms until the disease is advanced.
How Kidneys Work
Kidneys look like two small bean-shaped organs. They are located inside the ribcage, one on each side of the spine.
They clean our blood by removing waste and extra water, which comes out in the form of urine. Kidneys also keep the right balance of salt and minerals in our body. Moreover, they help control blood pressure and make red blood cells.
Our kidneys even keep our bones healthy. So, they work like natural filters that keep our body clean and strong, contributing to overall kidney health.
7 Early Warning Signs
You must be curious to know what signs of kidney damage should never be ignored. Keep reading the text below till the end to find out.
1. Foamy or Bubbly Urine (Proteinuria)
If your pee looks different from how it normally does, then don’t ignore it. It means that some protein is getting into your urine, something your kidneys shouldn’t allow.
When they don’t work properly, a bit of protein can slip through, and that’s what makes your pee look foamy or bubbly. This is also known as Proteinuria.
2. Increased Urination, Especially at Night (Nocturia)
To wake up frequently at night to pee can be a sign that your kidneys aren’t working well. They may be letting more water out of your body than normal, and it can be an early sign of kidney trouble.
This is also called Nocturia.
3. Swelling in Ankles, Feet, or Face (Edema)
When your kidneys don’t remove extra fluid and salt properly, your body starts keeping the extra water.
This can cause swelling in your feet, ankles, legs, or even around your eyes. This condition is called Edema.
4. Fatigue and Weakness
It’s easy to brush off tiredness as a lack of sleep or stress. But sometimes the real reason lies deeper in how your kidneys function.
They make a hormone called erythropoietin that helps your body produce red blood cells. When that signal weakens, your oxygen level drops and you start feeling drained more often than usual.
5. Dry or Itchy Skin
Healthy kidneys keep minerals like calcium and phosphorus in check. When that balance slips, waste can build up under the surface.
Over time, your skin may turn dry, itchy, or irritated in ways that regular lotions don’t help.
6. Blood in the Urine or Changes in Color
If your urine turns pink, red, or tea-colored, it’s worth paying attention.
Healthy kidneys usually keep blood cells where they belong, but damaged filters can let a few leak through. Sometimes it’s a minor issue like an infection or kidney stone, but other times it signals something more serious about kidney health.
7. Loss of Appetite, Nausea, or Weight Loss
When waste builds up in the bloodstream, food can start to taste metallic or unpleasant.
You might eat less without realizing it and lose a bit of weight over time. That loss of appetite and fatigue often appear before most people even know their kidneys are in trouble.
When to See a Doctor
If you’ve been feeling more tired than usual, noticing swelling in your body, or seeing changes in your urine, then don’t ignore these signs. It means your kidneys are working harder than they should.
A doctor can check how well your kidneys are working with a few simple tests:
- eGFR (Estimated Glomerular Filtration Rate) : A small blood test that shows how well your kidneys are filtering waste.
- Urine Protein Test : Your pee is checked for protein. When it shows up, it means your kidneys are under extra stress.
- Ultrasound : This scan lets doctors look directly at your kidneys to spot any blockages or changes in size or shape.
Finding out early makes treatment simpler and helps protect your kidney health for the long term.
Final Thoughts
Your kidneys do a lot for you every single day, often without you even noticing. But they need care too.
If you’ve seen any changes in your pee, swelling in your body, or you’re feeling tired all the time, don’t ignore it and get checked by a doctor.
A few simple tests can help catch problems early and keep you healthy. Staying aware and taking action early can make all the difference.
