4- Dry and itchy skin
If your skin is unusually dry and you experience persistent itching, it may be due to the buildup of toxins in your blood, a sign of kidney failure.
5- A metallic taste and bad breath
Breath that smells like ammonia and a persistent metallic taste can be caused by the buildup of waste products in the blood. It can also affect appetite and lead to weight loss.
6- Difficulty concentrating and dizziness
“Brain fog,” memory lapses, or difficulty concentrating can be signs that the kidneys are no longer filtering toxins properly, affecting the brain.
7- Lower back pain
Persistent lower back pain on one or both sides may be related to kidney stones, infections, or kidney cysts.
8- Constant fatigue
When the kidneys no longer produce enough erythropoietin (EPO), the hormone that stimulates the production of red blood cells, this leads to anemia and therefore excessive fatigue.
9- Frequent nausea and vomiting
The accumulation of toxins in the body can cause digestive upset, leading to nausea and loss of appetite.
