Abnormal skin colors
The skin is the largest organ of the body, usually one of the first parts that signal the internal problems.When the kidneys weaken, the skin becomes a "spokesperson" for changes that are happening inside the body.The accumulation of waste in the blood because the kidneys cannot be filtered, the skin loses a bright look, becomes dull or yellow.Along with that, the skin is dry and itchy, especially in the soles of the feet, causing discomfort, affecting the sleep and quality of life of the patient.
Leg edema
Edema is one of the early alarm signals that the body sends until the kidneys have problems.When the kidneys weaken, the ability to dialysis and eliminate waste, especially sodium and excess water, is significantly reduced.This excess water accumulates in tissues, causing swelling.
Often, we will most noticeable this sign in the feet and ankle, where the weight pulls the liquid down.However, edema can also appear in other areas such as puffiness, face and even spread to the whole body.

Numbness, aches in the legs
When the kidneys impaired function, hazardous waste accumulated in the blood is not filtered.This leads to nerves, especially nerves far away from the heart like the feet and lower legs, damaged.These nerves are responsible for inspiration and muscle control, so when damaged will cause symptoms such as numbness, burning, aches and pains
Patients with chronic renal failure often face many complications, in which the accumulation of calcium in soft tissue is a worrying problem.Calcium crystals formed under the skin not only cause pain but also makes the wounds difficult to heal, especially in areas under high pressure such as feet and lower legs.This makes the patient feel pain, discomfort and affect the ability to exercise.
Itching in the legs
Itching is a common and uncomfortable symptom in people with kidney disease.The main reason is due to the accumulation of toxins in the blood, stimulating sensory nerves under the skin and causing dermatitis reaction.Itching often spreads throughout the body, causing discomfort and affecting the quality of life.The treatment of itching not only helps to reduce symptoms but also an important part of kidney disease management
Extraordinary toenails change
The change in shape and texture of toenails is one of the early signs of kidney disease.Specifically, toenails can become unusually thick, brittle and brittle, even changing color into pale or dark yellow.These changes are often derived from the lack of essential nutrients and disorders of absorption process due to renal function.
