Lactate dehydrogenase, or LDH, is an enzyme found in nearly all body tissues. It plays a crucial role in energy production. When tissues are damaged, LDH is released into the bloodstream. Therefore, a high LDH level can indicate a variety of underlying health conditions. This article delves into understanding LDH, why elevated levels occur, and most importantly, practical strategies to lower your LDH level.
Understanding LDH and Its Significance
LDH is an enzyme involved in converting sugar into energy for your cells. It’s present in many tissues, including the heart, liver, muscles, kidneys, brain, and red blood cells. Measuring LDH levels is a common diagnostic tool because elevated levels can signify cellular damage or disease.
Normal LDH levels vary slightly depending on the laboratory and the testing methods used. Generally, the normal range for adults is around 120 to 246 U/L (units per liter). It’s essential to consult with your healthcare provider for accurate interpretation of your results, as they will consider your individual health history and other factors.
Why are LDH Levels Measured?
Doctors order LDH tests for several reasons, including:
- To help diagnose tissue damage.
- To monitor chronic conditions.
- To evaluate the effectiveness of treatment.
- To investigate specific symptoms that suggest tissue damage.
Interpreting High LDH Levels
An elevated LDH level doesn’t always pinpoint a specific condition but signals that tissue damage is occurring somewhere in the body. Some conditions associated with high LDH include:
- Heart attack: Damage to heart muscle releases LDH.
- Liver disease: Hepatitis or cirrhosis can cause elevated levels.
- Muscle injury: Intense exercise or trauma can increase LDH.
- Anemia: Breakdown of red blood cells releases LDH.
- Certain cancers: Some cancers can cause increased LDH production.
