Can weight loss after Laparoscopic sleeve gastrectomy ameliorate High BP ?

It was a retrospective cohort study of medical and clinical data of 305 patients who had undergone LSG. The researchers calculated the bariatric effect of LSG by calculating the percentage of total weight loss (%TWL), percentage of excess weight loss (%EWL) and BMI loss (%EBMIL). After surgery, they categorized the blood pressure as partial or total remission of hypertension.

Key findings of the study were:

• Among 305 patients, 143 were diagnosed with hypertension preoperatively with a median hypertension duration of 7.52 years.
• The researchers noted that the patients with hypertension had a higher prevalence of coexisting diseases (type 2 diabetes, dyslipidemia and obstructive sleep apnea) than patients with normal blood pressure.
• During one year observation period, they noted that 90 patients (63%) reduced antihypertensive medications and 33 patients (23%) discontinued the therapy.
• After 1 year of surgery, they found that

◊ %TWL in control group was 32.5 %, while in hypertensive group 29.1%,

◊ %EWL was 62.9% and 54.8% and,

◊ %EBMIL 73.9% and 63% respectively.

The authors concluded, " LSG is an effective method of obesity-related hypertension treatment. However, weight loss induced by Laparoscopic sleeve gastrectomy (LSG) does not affect the blood pressure status after the surgery."
