Can I eat fish if I have renal insufficiency?

The kidneys are very important to the human body. If there is a problem with the kidneys, the body's toxins cannot be excreted and normal urination will be affected. Renal insufficiency is a common disease with many causes. In addition to taking medication on time, you should also pay more attention to your diet when you have renal insufficiency.

Patients with renal insufficiency can eat some fish, but not too much. Pay attention to rest and prevent colds. Avoid spicy food, fatty meat, animal oil, animal offal and seafood.

The causes of renal insufficiency can be summarized as follows:

1. Kidney diseases: such as acute and chronic glomerulonephritis, pyelonephritis, renal tuberculosis, acute tubular degeneration and necrosis caused by chemical and biological poisons, kidney tumors and congenital kidney diseases.

2. Extra-renal diseases: such as systemic blood circulation disorders (shock, heart failure, hypertension), systemic metabolic disorders (such as diabetes) and urinary tract diseases (urinary stones, tumor compression), etc.

Clinical manifestations

In the early stage of renal insufficiency, there are only clinical symptoms of the primary disease, which can affect various organs and tissues throughout the body and cause corresponding symptoms:

Mental and nervous system manifestations include mental depression, fatigue, dizziness, headache, memory loss, insomnia, numbness of the limbs, burning pain in the hands and feet, itchy skin, and even unbearable itching and pain in the lower limbs, requiring frequent movement and inability to rest. In the late stage, drowsiness, irritability, delirium, muscle tremors and even convulsions, seizures, and coma may occur.
