The kidneys have lots of functions. –
They remove waste products from the body.
They balance the body’s fluids
They release hormones that keep your blood pressure steady
They produce red blood cells and
They help give you strong and healthy bones.
Blood is pumped from your heart to each kidney. The kidney then filters this blood through filters called nephrons and returns it cleaned to your heart. The waste product leaves your body through urine. If these nephrons are not working properly over a length of time this causes you to feel tired, sick and not very hungry.
It is very important that when this occurs that you see a doctor and that you eat the proper foods and a dietitian should be consulted. When you attend your clinic you will be able to talk to a dietitian and get good advice about what you should be eating and more importantly what you should avoid eating.
