Acidosis – Definition & Meaning

Acidosis is a term that is commonly used in the medical field to describe a condition where the pH level of the blood becomes too acidic. This can lead to a range of health problems if left untreated. In this article, we will explore the definition and meaning of acidosis, its origin, associations, synonyms, antonyms, and example sentences.


Acidosis is a medical condition characterized by an excess of acid in the blood. It occurs when the body produces too much acid or when the kidneys are unable to remove enough acid from the body. There are two types of acidosis: respiratory acidosis and metabolic acidosis.
Respiratory acidosis occurs when the lungs cannot remove enough carbon dioxide from the body, leading to an increase in acidity. This can be caused by conditions such as chronic obstructive pulmonary disease (COPD) or sleep apnea.
Metabolic acidosis occurs when there is an excess of acid in the body due to a build-up of acid or a loss of bicarbonate. This can be caused by conditions such as kidney disease, diabetes, or alcoholism.


The word acidosis comes from the Greek words “acid-” meaning sour and “-osis” meaning condition. The term was first used in the medical field in the early 20th century to describe a condition where the pH level of the blood became too acidic.
