E87: Other disorders of fluid, electrolyte and acid-base balance

E87.4: Mixed disorder of acid-base balance

There must be a certain acid content in our blood for our body to be able to function. The acid content is influenced by many processes. Among other things, the kidneys and lungs control the acid content in our body. If there are too many acids in the blood, these acids can then be converted into carbon dioxide. The carbon dioxide is then breathed out through the lungs. As a result, the acid content in the blood may be lowered. The kidneys affect the acid content in the blood. They may release excess acids into the urine if the acid content in the blood is too high. The kidneys may also release substances into the blood if the acid content in the blood is too low.

Your blood acidity levels were altered. In your case, that has several causes. The kidneys or liver may no longer work properly. It is also possible that you have lost many acids. That can occur for instance due to severe vomiting.
