Your kidneys, two bean-shaped organs, filter excess fluids, wastes, and toxins from blood. When damaged, they lose their filtering ability, leading to accumulation of toxic wastes.
When there is leak of protein into urine, foamy urine, also known as proteinuria, occurs. Foam or bubbles in the urine can be early sign of kidney damage or disease, as the kidneys are not able to filter waste and excess fluids properly, states Healthline.
Fatigue is a common symptom of kidney-related issues. When the kidneys are not functioning efficiently, they can't filter waste. It can lead to buildup of toxins in the body, causing feelings of tiredness, weakness, and lack of energy, suggests WebMD.
Another symptom of a kidney problem is no appetite. When the kidneys aren't working well, toxins remain in the body, causing a decrease in appetite. Additionally, kidney disease may cause nausea and vomiting, which leads to a decrease in appetite, reports Mayo Clinic.
Edema is another warning sign Due to the improper working, there may be a buildup of fluid in the body, causing swelling in the feet, legs, hands, and face, states Medical News Today.
Healthy kidney removes extra waste, fluid from the body and help to maintain the required amount of minerals required in your blood. Dry and itchy skin can be sign of less minerals and bone disease, that most often relates to kidney problems, states the National Kidney Foundation.
Nocturia or many occurrences of nighttime urination is due to the excessive fluid present in the body, thanks to poorly-functioning kidneys. Waking multiple times at night leads to improper sleep and tiredness throughout the day, states Healthline.
Another sign is broken sleep. Due to lack of proper sleep, the body doesn't get enough oxygen and that slowly hurts your kidney and in long run causes a chronic condition and, in turn, more lack of sleep, states WebMD.
