Summary
Lower vitamin A (vit A) levels are found in asthma patients. However, higher maternal vit A intake during pregnancy may increase asthma risk in children. Further research is needed to clarify vit A
Area of Science:
- Nutrition and immunology
- Respiratory medicine
- Epidemiology
Background:
- Vitamin A (vit A) plays a crucial role in immune function and epithelial development.
- Altered vit A status has been implicated in various inflammatory and respiratory conditions, including asthma.
- Understanding the relationship between vit A and asthma risk is essential for public health.
Conclusions:
- Serum vitamin A (vit A) levels are demonstrably lower in individuals with asthma.
- Increased maternal vit A intake during pregnancy may be linked to a higher risk of asthma development in offspring by age 7.
- The complex interplay of vit A, asthma risk, and influencing factors like age, diet, and genetics necessitates further investigation.

Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
