Incapacity benefit is only paid after 26 weeks of illness, therefore anybody employed should have had their employer making checks.
Unemployed are slightly different it depends on linking claims as to when Incapacity benefit starts.
When a person receives Incapacity benefit their claim is referred to a state doctor periodically, this doctor will consult the GP/Consultant and can if he so decides request the patient to attend a medical examination, and can stop the benefit or allow it to continue
A lot of these diagnosisis are the initial one made by the GP, due to patients confidentiality rules the Benefit office will NOT be informed of a more serious diagnosis.
This list is flawed, misleading and is just goverment spin.
I note some ABers have only picked up obesity, what about long term sick with Flu?. An initial diagnosis of obesity could actually prove to be a serious disease of the adrenal glands.
