Dialysis, in chemistry, separation of suspended colloidal particles from dissolved ions or molecules of small dimensions (crystalloids) by means of their unequal rates of diffusion through the pores of semipermeable membranes.

Dialysis is a treatment that filters and purifies the blood using a machine. This helps keep your fluids and electrolytes in balance when the kidneys can’t do their job. Dialysis has been used since the 1940s to treat people with kidney problems.

In hemodialysis, the wastes and excess water are removed by using an external filter called a dialyzer, which contains a semipermeable membrane. The separation of wastes is done by creating a counter-current flow gradient, where blood flow is in one direction and the fluid of the dialyzer is in the opposite direction.

Watermelon is healthy because it’s full of lycopene – an antioxidant that helps break down harmful free-oxygen radicals. It prevents kidney injury and therefore, is a kidney-friendly food.

Cabbage, kale, broccoli, Brussels sprouts and cauliflower are all from the cruciferous family of vegetables. They’re on the alkaline side, making your diet less acidic and providing less pressure on your kidneys. Plus, they are loaded with vitamins A and C, as well as calcium and other important minerals.

Salmon, tuna, and other cold-water, fatty fish that are high in omega-3 fatty acids can make a beneficial addition to any diet.

Although shrimp has more cholesterol than other seafood, the amount is still reasonable for a kidney diet. Plus, there’s practically no fat in a serving of shrimp. Look for fresh shrimp that has never been frozen, and check the labels for added phosphates or salt.
