Energy balance

Intragastric balloons (IGBs) and oral superabsorbent hydrogels (OSH) provide moderate weight loss (10-15% TBWL for IGBs, ~10% for OSH) by physically occupying stomach volume and triggering satiety signals, serving as minimally invasive alternatives for patients who are not surgical candidates.

If you are not a candidate for surgery or drugs, or want a temporary, non-surgical option, intragastric balloons or hydrogels can help. Balloons are placed in the stomach for 6-12 months to take up space and make you feel full, leading to 10-15% weight loss. Hydrogels are swallowed before meals and expand to trigger satiety. These are less effective than surgery or GLP-1 drugs long-term but offer a middle ground for those avoiding needles or surgery.

ModerateSupportsMEDIUM confidence
Studies have shown results of weight loss typically around 10-15% of total body weight within six months of placement.[99][108] ... Around 27% of overweight or obese participants lost at least 10% of their total body weight, furthermore, 60% of patients also attained significant weight loss, which is 5% or more.
