Obesity in mothers is linked to raise chance of asthma flare-ups during pregnancy as well as an elevated chance of asthma in the children. The same proinflammatory pathways that produce asthma in children may also have an impact on maternal asthma because of gestational weight increase during pregnancy. The goal of this research was to ascertain how much excessive weight gain during the first trimester of pregnancy affected asthma flare-ups. One hundred asthmatic patients were present in this study and split up into two groups. 50 patients with asthma who gained excessive weight during pregnancy and 50 patients with asthma who gained weight on average Regarding weight at the conclusion of the first trimester, The study's groups that were compared showed a statistically significant difference There is a noticeable increase in body weight among each group. Furthermore, a statistically significant difference in the percentage rise in bodyweight (much larger in the group experiencing excessive weight gain) exists between the analyzed groups, losing weight is linked to an improvement in asthma a control, a more than fifty percent decline of asthma symptoms and an enhancement in lung function. In conclusion, pregnancy-related asthma exacerbations are linked to increase of weight in first three months of pregnancy.
