Yes, kidney disease, especially in advanced stages, often causes unintentional weight loss due to poor appetite, nausea, changes in taste, metabolic issues, and inflammation, leading to decreased food intake and muscle/fat loss (wasting syndrome). This weight loss is a serious symptom indicating worsening kidney function and a higher risk for poor outcomes, so it's crucial to see a doctor.
Symptoms can include:
There's no cure for chronic kidney disease (CKD), but treatment can help relieve the symptoms and stop it getting worse. Your treatment will depend on the stage of your CKD. The main treatments are: lifestyle changes – to help you stay as healthy as possible.
Kidney damage is now mild to moderate and your kidneys are beginning to struggle with filtering waste and extra fluid out of your blood. Stage 3 CKD is split into two stages: 3a and 3b. At 3a, your eGFR is 45-59ml/min. At 3b, your eGFR is 30-44ml/min.
Signs and symptoms of Stage 1 CKD include:
You can check kidney function at home using at-home test kits for urine (detecting protein/albumin) or finger-prick blood tests (checking creatinine/eGFR), often with smartphone apps for analysis, or by monitoring symptoms like increased nighttime urination (nocturia), swelling, or changes in urine (blood, foam) and discussing results with a doctor, as home tests screen but don't replace professional diagnosis.
In nondialyzed chronic renal failure patients and in maintenance dialysis patients, anorexia is related mainly to the accumulation of unidentified anorexigenic compounds, inflammatory cytokines, and alterations in appetite regulation, such as amino acid imbalance, which increases the transport of free tryptophan across ...
Chronic kidney disease usually progresses slowly. Regular blood and urine tests can help doctors to decide whether the kidneys are still working well enough, whether the treatment needs to be adjusted, or whether dialysis will be needed soon, for example.
The top 10 drugs commonly linked to kidney damage
These may include:
To strengthen your kidneys, focus on a healthy lifestyle: stay hydrated with water, eat a balanced diet low in salt and processed foods, exercise regularly, maintain a healthy weight, and avoid smoking and excessive alcohol, while also managing blood pressure and blood sugar to prevent damage.
The goal of CKD treatment is to slow the damage to your kidneys and keep them working as well as they can for as long as possible. In time, though, many people's kidneys work less and less well, leading to kidney failure. If this happens, you will need dialysis or a kidney transplant.
Kidney damage cannot be reversed or repaired, but you can keep it from getting worse. Following your treatment plan and making healthy life changes, can help keep your kidneys working for as long as possible.
Symptoms of kidney disease
Where do I feel kidney pain? You feel kidney pain near the middle of your back, just under your ribcage, on each side of your spine where your kidneys are. Your kidneys are part of the urinary tract, the organs that make and remove urine from the body.

Top 10 Drugs That Cause Kidney Damage
Over-the-counter NSAIDS
They are not safe to use when you have kidney disease. Ibuprofen, such as Advil™ and Motrin™. Naproxen, such as Aleve™ and Naprosyn™. Aspirin for pain relief.
Diabetes and high blood pressure are the top culprits damaging kidneys most, as they harm the delicate filtering blood vessels, leading to chronic kidney disease (CKD) and failure; other major factors include smoking, obesity, dehydration, poor diet (high sugar/salt/red meat), certain medications (NSAIDs), lack of sleep, and genetic conditions. These factors create a cycle where damaged kidneys worsen blood pressure, further damaging them.
Extreme, on-going tiredness, together with a lack of energy, is often called fatigue. There are lots of reasons why you may experience fatigue with CKD. If your kidneys are not working well, toxins (waste products) build up in your blood and this can make you feel tired and weak.
When chronic kidney disease becomes advanced, loss of kidney function can cause:
In the general population, approximately 38% of adults aged 70 or older have an estimated glomerular filtration rate (eGFR) < 60 ml/min/1.73 m2, with most having moderate reductions in eGFR in the 30-59 ml/min/1.73 m2 range (1).
Although inadequate nutrition may contribute to wasting or cachexia, other factors including systemic inflammation, perturbations of appetite-controlling hormones from reduced renal clearance, aberrant neuropeptide signaling, insulin and insulin-like growth factor resistance, and metabolic acidosis, may be important in ...
A severe decrease in kidney function can lead to a buildup of toxins and impurities in the blood. This can cause people to feel tired or weak and can make it hard to concentrate. Another complication of kidney disease is anemia, which can cause weakness and fatigue.
A loss of appetite is usually a sign of concern if it lasts for longer than a week. A loss of appetite can come with additional symptoms like: Fatigue or low energy.
