However kidney size are normal. no other complain except fatty liver. Is this size of cortical cyst is dangerous? What precautions,/diet/ medicine he should take? [/INST] Hi, dearI have gone through your question. I can understand your concern.There are many ways to treat the cortical cyst.Puncture of cyst or decortication of cyst is used in large cyst. Drugs are useful to relieve pain only. They can not cure the cyst.Changing the way you eat can make a big difference in how long the cysts stay and whether they come back. You should avoid spicy and fatty foods, foods that are stimulants (like coffee or sodas) and processed foods. Smoking and drinking can also increase problems with the kidneys, so it pays to stop both activities altogether. Take low sodium diet to relieve pressure on kidney. Consult your doctor and plan accordingly.Hope I have answered your question, if you have any doubts then contact me at bit.ly/Drsanghvihardik, I will be happy to answer you.Thanks for using health care magic.Wish you a very good health. </s>
