Is this kidney disease?

My 65-year-old uncle recently noticed swelling in his ankles and some other parts of his body. Kindly let me know if this is due to Kidney disease.

Yes, kidney disease can lead to swelling in the ankles or other parts of the body, and this condition is medically referred to as edema, particularly in the ankles. The condition can also get worse at night. This is because, the kidneys are responsible for filtering waste and excess fluids from the blood, which are then excreted in the urine.

In people with kidney disease, the kidneys are less able to perform this function efficiently. When the kidneys fail to filter out excess sodium and fluids properly, these fluids accumulate in the tissues, leading to swelling.

The ankles are a common site for swelling because of the effect of gravity. During the day, when you are standing or sitting, fluid tends to pool in the lower extremities, such as the ankles, due to gravity. In kidney disease, since the body retains more fluid, it often becomes noticeable as swelling in the feet and ankles. If the swelling does not go away or worsens over time, it can indicate worsening kidney function or complications.

Also, if fluid buildup affects the lungs, it can lead to Pulmonary Edema causing shortness of breath, which is a medical emergency.  Rapid weight gain due to fluid retention can be another sign of worsening edema. It is always advisable to see a doctor for proper checkup in case of swelling of any part of the body.
