Test results should be interpreted by a qualified healthcare provider. [Content pending medical review.]
Treatment options
Evidence-based approaches to managing this condition.
First-line treatments
Exercise prescription and weight management
Treatment options should be discussed with a qualified healthcare provider.
Leukotriene receptor antagonists
Pharmacological agents such as montelukast may help modulate leukotriene pathways and compensate for reduced circulating leukotriene C4 concentrations by blocking receptor-mediated inflammatory cascades.
Omega-3 fatty acid supplementation
Increased dietary intake of omega-3 fatty acids from fish oil or flaxseed can support anti-inflammatory eicosanoid production and help restore inflammatory balance.
Additional treatment options
Anti-inflammatory diet modification
Adopting a Mediterranean-style diet rich in fruits, vegetables, and healthy fats may help reduce overall inflammatory burden and support optimal leukotriene function.
dietarySmoking cessation and environmental control
Eliminating tobacco exposure and reducing contact with environmental pollutants decreases inflammatory triggers that may exacerbate symptoms associated with leukotriene deficiency.
lifestyleInflammatory biomarker tracking
Regular monitoring of inflammatory markers such as C-reactive protein and urinary leukotrienes helps assess disease progression and treatment response over time.
