Clinical Report



This study aimed to assess the impact of intragastric balloon (IGB)-induced body weight loss on metabolic syndrome in obese patients and evaluate what happens during 1-year follow-up.


To this end, data were collected on 143 obese patients (body mass index (BMI) 36.2 ± 5.7 kg/m²) who underwent IGB insertion between January 2000 and December 2005. Outcomes were recorded at BioEnterics Intragastric Balloon removal time (t0) and at 6-month (t6) and 12-month (t12) follow-up.


Significant BMI, excess body weight loss percentage, and body weight loss percentage (BWL%) were observed at t0 (29.6 ± 4.6 kg/m²; 29.3 ± 4.8%; 14.1 ± 5.7%), followed by partial weight regain at t12 (32.4 ± 4.3 kg/m²; 26.1 ± 4.9%; 11.2 ± 4.6%). Incidence of metabolic syndrome dropped from 34.8% (pre-IGB value) to 14.5% (t0) and 11.6% (t12). Likewise, type 2 diabetes mellitus (DM), hypertriglyceridemia, hypercholesterolemia, and blood hypertension (BH) incidence decreased from 32.6%, 37.7%, 33.4%, and 44.9% (pre-IGB values) to 20.9%, 14.5%, 16.7%, and 30.4% at t0 and 21.3%, 17.4%, 18.9%, and 34.8% at t12. HbA1c blood concentration shifted from an initial value of 7.5 ± 2.1% to 5.7 ± 1.9% (t0), 5.6 ± 0.7% (t6), and 5.5 ± 0.9% (t12). Patients suffering from DM or BH stopped or diminished relative drug consumption at t12. Negligible modifications were reported as regards HDL cholesterol and hyperuricemia.


Weight regain is commonly observed during long-term follow-up after IGB removal. Nevertheless, the maintenance of at least 10% of the BWL%, as reported at 1-year follow-up, is associated with an improvement in metabolic syndrome.
