Summary
Bariatric and medical weight management: the procedures, preparing for surgery, the staged diet, protein and fluid, supplements, activity, dumping, alcohol, pregnancy, labs, weight recurrence, the non-surgical routes and the medical-information policy
'''Two surgical societies published a joint statement in 2022 setting out who metabolic and bariatric surgery is indicated for.''' It is written for clinicians, and it is the start of a conversation rather than a test you pass.
== What the statement says ==
+ Surgery '''is recommended''' for people with a BMI over 35, whatever else is or is not going on: "MBS is recommended for individuals with BMI >35 kg/m², regardless of presence, absence, or severity of co-morbidities" (Eisenberg D et al., ''Obesity Surgery'', 2023 — [https://doi.org/10.1007/s11695-022-06332-1 doi:10.1007/s11695-022-06332-1]).

+ Surgery '''is recommended''' for people with type 2 diabetes and a BMI over 30 (Eisenberg D et al., ''Obesity Surgery'', 2023 — [https://doi.org/10.1007/s11695-022-06332-1 doi:10.1007/s11695-022-06332-1]).

+ Surgery '''should be considered''' for people with a BMI of 30–34.9 who have not reached a substantial or lasting result with non-surgical treatment (Eisenberg D et al., ''Obesity Surgery'', 2023 — [https://doi.org/10.1007/s11695-022-06332-1 doi:10.1007/s11695-022-06332-1]).

+ '''BMI thresholds are lower for Asian populations.''' Clinical obesity is recognised at a BMI over 25, and the statement says access should not be denied on traditional BMI zones alone (Eisenberg D et al., ''Obesity Surgery'', 2023 — [https://doi.org/10.1007/s11695-022-06332-1 doi:10.1007/s11695-022-06332-1]).

+ '''There is no upper age limit''' — older people who could benefit are to be considered after careful assessment of their other conditions and frailty (Eisenberg D et al., ''Obesity Surgery'', 2023 — [https://doi.org/10.1007/s11695-022-06332-1 doi:10.1007/s11695-022-06332-1]).

== It is treatment for a long-term condition ==
+ The same statement is explicit that severe obesity is a chronic disease and that an operation is the start of long-term management rather than the end of it (Eisenberg D et al., ''Obesity Surgery'', 2023 — [https://doi.org/10.1007/s11695-022-06332-1 doi:10.1007/s11695-022-06332-1]). That framing is why this whole part of Loopa is built around what happens for years afterwards — the supplements, the labs, the protein, the follow-ups — and not around a date.

== What Loopa does with this ==
'''Nothing.''' Loopa does not work out whether any of the above describes you, does not calculate your eligibility, and does not tell you to have an operation. It shows you what the published statement says so you can take it into a conversation. Your care team decides, with things this app cannot see.
