“…24 Other studies by Kharodi et al, Ashraf et al, Biring et al, and Ahmed and Morgan also stated that obesity was associated with a significant decline of FEV 1 . 3,14,25,26 Contrary to our study, a study by Bhattacharjee et al showed a significant increase in FEV 1 with obesity. 21 In the present study, PEFR declined non-significantly (p >0.05) in group B when compared to group A as shown in Table 2.…”

Aim and objective: To study the effects of obesity on the pulmonary functions in male medical students of Amritsar . Materials and methods: Pulmonary function tests (PFTs) of normal, healthy, male medical students of Amritsar were determined and were compared and correlated with other studies. Criteria for obesity in our study taken were according to WHO criteria of BMI. The PFTs were carried out with a computerized spirometer "Med-Spiror". The data were collected; compiled, statistically analyzed, and valid conclusions were drawn. Higher lung volumes and flow rates were achieved. Results: There was a statistically highly significant decline in forced vital capacity (FVC) in obese when compared with nonobese groups. The values of forced expiratory volume in first second (FEV 1 ) in both groups when were compared showed significant changes. The ratio of FEV1/ FVC, the values of peak expiratory flow rate (PEFR), and forced mid-expiratory flow (FEF 25-75% ) showed insignificant changes but maximum voluntary ventilation (MVV) when were compared showed highly significant changes. Conclusion:There is a decline of various respiratory functions in obesity. The cause of the decline of various respiratory functions in obesity may be due to a decrease in distensibility of the chest wall or limited expansion of the thoracic cavity and is the cause for reduced ventilatory volumes and total lung capacity.

“…In obese people, a restrictive respiratory deterioration is characteristic with a decrease in thoracic compliance and pulmonary elasticity. These alterations predispose them to the appearance of respiratory complications during any anesthetic-surgical act (Hatem et al, 2019). If one takes into account that there is a restrictive component due to obesity itself to which an obstructive disease such as bronchial asthma or chronic obstructive pulmonary disease can be added, then it is logical to think that perioperative complications related to these alterations may occur, which can explain what was found in the present investigation.…”

Introduction:The obese patient who is treated with laparoscopic bariatric surgery is complex for the anesthesiologist because of its anatomofunctional characteristics and associated diseases. Objective: To identify the presence of perioperative complications and their relationship with preoperative factors and intraoperative anesthetic behavior that may constitute indicators of prediction of complications. Materials and Methods: An analytical, observational, longitudinal, retrospective study was carried out in 476 obese patients surgically operated by laparoscopic vertical gastroplication. Immediate intraoperative and postoperative clinical complications and their relationship with demographic, clinical, anthropometric and anestheticdependent variables were identified, which constituted risk factors. With the risk factors identified, a prognostic index was constructed and subsequently validated. Results: The immediate intraoperative and postoperative complications were few. It was possible to identify three independent risk factors, given by the previous respiratory functional status, the anesthetic technique used and the surgical time. A prognostic index of complications was constructed that grouped patients at low, intermediate and high risk of presenting complications. Conclusions: The grouping of risk factors as a predictive index of complications was effective because the complication prediction capacity could be estimated and validated.

“…Similar results were reported by several studies. 1,[4][5][6]14 Reduction in lung capacity and FVC accompanied by reduced FEV1, were the most frequent findings in these studies, suggesting the presence of a restrictive ventilatory pattern associated with obesity.…”

“…This results in the decline of pulmonary function and causes extra work of breathing. 6,14 • Also, obesity causes increased release of many inflammatory markers such as interleukin-6, tumor necrosis factor-alpha, leptin and adiponectin. These may act via systemic inflammation to negatively affect pulmonary function.…”

Background: Obesity has long been recognized to have significant effect on respiratory functions. Many studies have reported exponential decrease in pulmonary function test (PFT) with increasing body mass index (BMI), which is a crude indicator of obesity. Also, the relationship between BMI and PFTs varies with age, race, geographical region and the different obesity standards used. To the best of our knowledge, not many studies have been done to examine the relationship between obesity and lung volumes among adults in our region, Jammu. This cross-sectional study was carried out with the objective of evaluating the effect of obesity on lung function test in obese but otherwise healthy adults of Jammu region.Methods: This cross-sectional study was conducted in Jammu region on subjects selected randomly from different colleges in the age group of 18-40 years. The study involved 300 subjects; divided into three groups of 100 each, based on BMI into normal, overweight and obese groups. Four respiratory parameters viz. FVC (Forced Vital Capacity), FEV1 (Forced Expiratory Volume in 1 second), FEV3 (Forced Expiratory Volume in 3 seconds), and MVV (Maximum Voluntary Ventilation) were used to assess their lung functions.Results: All the respiratory parameters exhibited statistically significant decrease in obese groups as compared to normal and overweight groups.Conclusions: The present study suggests that obesity alters the respiratory physiology by producing a restrictive ventilatory pattern.
