Am new to this. Can kidney disease be caused by anything else besides high blood pressure, hereditary, hypertension etc.? Because I have none of these and the doc found that I have ckd (a thick layer around my kidney). Mild ckd she suggest. Can this be the reason why I'm fatigue, feeling weak, loss of appetite, weight loss, itchy skin, even at this stage? I also have bad anxiety, health anxiety, and am very stressed. Was told this cam cause those same symptoms. Please advise as I have never been through any problems in my life until june about my health or my kidneys. I am very afraid.
