Acidosis is a medical condition characterized by an excess of acid in the body fluids, leading to a decrease in blood pH. This can occur due to various factors, including respiratory issues, where the lungs cannot remove enough carbon dioxide, or metabolic problems, where the body produces too much acid or fails to remove it effectively. There are two main types of acidosis: respiratory acidosis and metabolic acidosis. Respiratory acidosis is often caused by conditions like chronic obstructive pulmonary disease (COPD) or severe asthma, while metabolic acidosis can result from conditions such as diabetes or kidney disease. Proper diagnosis and treatment are essential to restore the body's acid-base balance.
