How kidney disease feels physically
The symptoms of kidney disease may physically include the feeling of having a flu all the time. For example, the person with kidney disease may feel:
Tiredness and weakness
They may feel tired and weak, so that it's hard for them to manage walking up a flight of stairs or take a walk around the block. They may feel the need to sleep more than they usually do.
Coldness and temperature
They may feel cold all the time, as if they have a fever.
Lack of concentration and forgetfulness
They may have trouble concentrating or may forget things more than is usual for them. These symptoms are most often due to anemia - a shortage of red blood cells - which can be treated.
