Obesity, asthma, and vitamin D deficiency in pregnancy: Cause or consequence?

Vitamin D levels can affect the activity level of asthma, especially in obese individuals. Therefore, it is pertinent to pose the following questions: Does vitamin D deficiency in the early pregnancy increase the risk of exacerbation of asthma and excessive weight gain during pregnancy? Does obesity influence the response to vitamin D supplementation in pregnant women with asthma? What is the safe dosage of vitamin D for supplementation among pregnant women with asthma?
