Y43.6: Enzymes, not elsewhere classified

Enzymes, not elsewhere classified, refers to a medical situation where certain enzyme levels in the body are abnormal. Enzymes are proteins in the body that speed up chemical reactions, and they play a critical role in numerous bodily functions such as digestion, metabolism, and immune response. When the level of these enzymes becomes unusually high or low, it can indicate a potential health issue. Abnormal enzyme levels can result from a variety of causes including disease, infection, or certain medications that may affect the production or function of the enzymes. Symptoms can be varied based on which enzyme is involved and the underlying cause, but can include fatigue, nausea, weight loss or gain, and changes in heart rate. The specific impact of abnormal levels can be broad and affect multiple bodily systems, potentially resulting in conditions such as liver disease, pancreatitis or metabolic disorders.
