Bariatric surgery is one of the most promising weight loss options for obese individuals with comorbidities. After bariatric surgery an individual loses significant amount of weight, ranging from 4-6kgs in first month itself depending on type and grade of obesity as well as type of surgery. This weight loss plays a major role in metabolic changes occurring in the body. These changes are directly correlated to physiological parameters like heart rate and blood pressure, the normalcy of which is not yet confirmed by numerous researches found in databases. Materials and methodology: Observational study conducted on cohort of 250 subjects undergoing bariatric surgery. The subjects heart rate and blood pressure were monitored at two instances pre-surgery and post-1month surgery. Results: Significant difference was found for resting heart rate (p<0.05) and blood pressure (p<0.05) post-surgery. It suggests decrease of at least 3bpm in RHR, 7mmHg in SBP and 2mmHg in DBP. Conclusion: Bariatric surgery is effective in reducing RHR and BP significantly in short span of 1-month.
