Can patients with kidney disease eat fish?
My mother used to love eating fish, but since being diagnosed with kidney disease, she has completely avoided it and has been very careful with her diet. Today, she really wants to eat fish. May I ask if patients with kidney disease can eat fish?

Kidney disease patients can eat fish, but they should pay attention to the selection and amount of fish consumed.
For most kidney disease patients, moderate fish consumption is beneficial. Fish is a good source of high-quality protein and rich in Omega-3 fatty acids, which help reduce the risk of cardiovascular disease—one of the common complications in patients with chronic kidney disease. However, when kidney function is severely impaired, such as in advanced stages of chronic kidney disease or during uremic phases, patients may need to limit protein intake to reduce the burden on the kidneys.
Patients are advised to choose freshwater fish, as they are low in cholesterol and fat and provide high-quality protein suitable for kidney disease patients. Sea fish, on the other hand, contain higher levels of purines and should be avoided by kidney disease patients. When cooking fish, patients should avoid using overly salty, greasy, or spicy seasonings and opt for healthy cooking methods such as steaming or stewing.
In addition, kidney disease patients should closely monitor their condition after eating fish. If symptoms such as worsening edema, elevated blood pressure, or other discomforts occur, prompt medical attention should be sought.
