I want to find all instances where a patient has been diagnosed with type II diabetes mellitus (non-insulin dependent type or adult-onset type) or unspecified type, either uncontrolled or not stated as uncontrolled, with or without ketoacidosis, within the same instance number as a diagnosis of obesity. The query will look for the first occurrence of type II diabetes mellitus and the second occurrence of obesity, and the time between the two events must be less than or equal to each other.
