Millions of people across the world have kidney disease, yet most don't know they have it. According to experts, there are a number of physical signs of kidney disease, but mo them are attributed to other conditions.

And that is why those affected usually do not experience symptoms until the very late stages, when the kidneys are failing or when there are large amounts of protein in the urine. While the only way to know if you have kidney disease is to get tested, there are a few signs you need to watch out for that can happen in your legs.

Swelling and puffiness

According to experts, swelling in your legs can be a sign of kidney disease. When your kidneys become impaired, their ability to lose excess fluid from the body diminishes, which causes fluid buildup and swelling in the legs and other areas. Also, due to sodium or salt retention, you may see swelling around your ankles and feet.

Cold feet

According to doctors, cold feet can be a symptom of kidney disease, even though it is not a definitive indicator on its own. Experts say that while kidney issues can lead to a range of symptoms, cold feet happen due to poor circulation, anemia, and reduced ability to regulate body temperature.

Itching

Extremely itchy skin is a common symptom of advanced kidney disease. Doctors say the itch ranges from irritating to life-disrupting and can be debilitating in no time. Around your knees and calves, your skin may itch all the time. Some people have an itch in one area of their skin.

Pain in the legs

Pain in your legs and feet can be a symptom of kidney disease, especially if the disease progresses. Kidney disease leads to swelling in your extremities, including the legs and feet, which causes discomfort and extreme pain. Also, according to experts, kidney disease can lead to nerve damage, which can cause pain, numbness, or tingling in the legs and feet.

Changes in the colour of the skin

Kidney disease causes dry, itchy skin, and in severe cases, skin colour changes or pigmentation. Kidney damage, especially in the advanced stages, includes skin discolouration, dry and itchy skin, swelling, and in some cases, even the development of ulcers. As the kidneys struggle to filter waste, toxins accumulate, leading to a yellowish or brownish discolouration of the skin.
