Note: No specific SOP exists for obesity below morbid obesity threshold. Analysis conducted using morbid obesity SOPs as analogous framework given similar pathophysiology and risk factors.
ADF History
The veteran, Medic/Medical Operator/Medical Technician, enlisted 06 December 2001, transferring to SERCAT 5 (Reserve Service) on 23 Mar 2022.
Occupational History
Military medics face significant occupational challenges that contribute to weight management difficulties including irregular meal schedules during deployments and field exercises, reliance on high-calorie processed ration packs, limited access to fresh foods during operational periods, disrupted sleep patterns affecting metabolism, high stress levels leading to emotional eating, physical injuries limiting exercise capacity, and sedentary periods during recovery from musculoskeletal injuries. The demanding nature of medical duties combined with shift work and deployment stressors creates an environment conducive to weight gain.
History
The veteran an Army Medic, developed obesity during her military service beginning in 2004 after initial weight gain during training, reaching a peak BMI of 37.1 in 2012. She had been overweight during childhood and adolescence but successfully lost 25kg before enlistment in 2003, however regained weight during Initial Employment Training.
Timeline
- July 2009: Documented BMI 34.4 representing Class I obesity during routine medical examination. This measurement occurred approximately 6 years after enlistment and demonstrated significant weight gain since her pre-military weight loss. The BMI placed her in the obesity category despite military fitness requirements. Associated health impacts included increased cardiovascular risk and potential contribution to musculoskeletal problems. Weight management counseling was provided but competing military demands made adherence challenging.
- June 2011: Peak weight recorded with BMI 37.1 reaching Class II obesity during medical review. This represented her highest documented weight throughout military service, occurring during a period of multiple musculoskeletal injuries including bilateral carpal tunnel syndrome requiring surgery. The progression from BMI 34.4 to 37.1 over two years indicated continued weight gain despite awareness and military fitness standards. This coincided with limited physical activity due to surgical recovery and chronic pain conditions. Intensive weight management intervention was clearly indicated at this stage.
- Mar 2012: Weight reduction achieved with BMI 31.04 following Medical Employment Classification Review. The veteran demonstrated approximately 15-20kg weight loss from her peak, likely motivated by career implications and fitness requirements. Despite the improvement, she remained in the Class I obesity category indicating ongoing metabolic challenges. The reduction occurred through structured intervention and increased motivation during her employment review process. Continued weight loss efforts were encouraged to reach healthy BMI range.
- August 2019: Significant improvement documented with BMI 27.24 falling into overweight category. This represented sustained weight loss of approximately 30-35kg from her peak weight over 7 years, demonstrating remarkable personal commitment. She had successfully transitioned from Class II obesity to overweight status, indicating effective long-term lifestyle modifications. This improvement coincided with resolution of acute musculoskeletal issues and improved physical activity tolerance. The achievement represented one of her most significant health improvements during service.
Symptoms
Initially, the veteran experienced gradual weight gain during Initial Employment Training in 2004 with associated decreased fitness performance and increased difficulty meeting military physical standards. During her peak obesity period (2012), she likely experienced reduced exercise tolerance, joint stress contributing to musculoskeletal problems, potential sleep disturbances, and metabolic changes affecting energy levels. Currently, following her significant weight loss achievement, she has demonstrated improved physical capacity, better management of comorbid conditions, and enhanced overall health status, though she remains slightly above ideal BMI range.
Imaging
No specific imaging performed for obesity assessment. Related imaging included abdominal ultrasound on 23 May 2013 showing mild hepatic steatosis consistent with obesity-related fatty liver disease.
1. What is the formal diagnosis of the condition claimed above?
The formal diagnosis is Obesity (ICD-10: E66.9). Analysis conducted using DVA SOPs 44/2022 (Balance of Probabilities) and 43/2022 (Reasonable Hypothesis) for morbid obesity applied by analogy, as no specific SOP exists for obesity below BMI 40 threshold.
Obesity is a chronic disease characterized by excessive accumulation of body fat resulting in BMI ≥30 kg/m². It represents a complex multifactorial condition involving genetic, environmental, psychological, and behavioral factors. Class I obesity (BMI 30-34.9), Class II obesity (BMI 35-39.9), and Class III obesity (BMI ≥40) represent increasing severity levels with corresponding health risks including cardiovascular disease, type 2 diabetes, sleep apnea, osteoarthritis, and certain cancers.
The veteran progressed from Class I obesity (BMI 34.4 in 2010) to Class II obesity (BMI 37.1 in 2012) before achieving weight reduction to overweight status (BMI 27.24 in 2020). The temporal relationship demonstrates onset during military service with peak severity mid-career, followed by successful long-term weight management achieving near-normal BMI range.

When did the veteran first present to a health / medical provider for this condition? First documented obesity assessment occurred during routine medical examination in July 2009 when BMI 34.4 was recorded, presenting to military medical officers as part of routine health screening. [CHART REVIEW - MELISSA CAMPBELL - FINAL.docx, obesity timeline section]
When was the condition confirmed / formally diagnosed? Obesity was formally confirmed in July 2009 when BMI 34.4 was documented during routine medical examination by military medical staff, meeting clinical criteria for Class I obesity (BMI ≥30). [CHART REVIEW - MELISSA CAMPBELL - FINAL.docx, conditions section item 57]
When did the veteran first present to you (or your practice) for this condition? 22 November 2020.
3. How was this diagnosis confirmed? i.e. what were the key symptoms and signs, investigation results, specialist opinions? Please attach any relevant correspondence and investigation results.
The diagnosis was confirmed through objective BMI measurements demonstrating BMI ≥30 consistently over multiple years. Key measurements included BMI 34.4 (July 2009), BMI 37.1 (June 2011), BMI 31.04 (Mar 2012), and BMI 27.24 (August 2019). Associated findings included hepatic steatosis on abdominal ultrasound (July 2014) and gallbladder polyps, both consistent with obesity-related metabolic changes. Clinical correlation included weight-related musculoskeletal stress contributing to joint pathology and reduced exercise tolerance during peak obesity periods.

Using morbid obesity SOP factors by analogy:
Having a caloric intake that is excessive for energy needs for at least the 5 years before the clinical onset of obesity - MET Military service from 2004-2010 involved high-calorie field rations, irregular meal timing during exercises and deployments, limited access to fresh foods, and stress-induced eating patterns contributing to sustained caloric excess leading to obesity onset in 2010.
Taking a drug from the specified list of drugs for at least the 6 months before the clinical onset of obesity - NOT MET No documented use of weight-gaining medications from the specified list (carbamazepine, gabapentin, insulin, lithium, antidepressants, etc.) during the 6 months prior to obesity onset in 2010.
Taking an antipsychotic drug for at least the 3 months before the clinical onset of obesity - NOT MET No documented antipsychotic medication use prior to obesity onset in 2010.
Taking at least 5 milligrams of prednisone per day, or equivalent glucocorticoid therapy, for at least the 3 months before the clinical onset of obesity - NOT MET No documented corticosteroid therapy prior to obesity onset, though NSAIDs were used for musculoskeletal conditions from 2018 onwards.
Having binge eating disorder or night eating syndrome for at least the 1 year before the clinical onset of obesity - NOT MET No documented eating disorders, though irregular military meal schedules may have contributed to disordered eating patterns.
Having a clinically significant disorder of mental health as specified for at least the 3 years before the clinical onset of obesity - NOT MET Adjustment disorder was diagnosed in December 2010, after obesity onset in 2010. However, workplace stress and relationship difficulties likely predated formal diagnosis.
Having Cushing syndrome for at least the 3 months before the clinical onset of obesity - NOT MET No documentation of Cushing syndrome or related endocrine disorders.
Having hypothyroidism for at least the 3 months before the clinical onset of obesity - NOT MET No documented thyroid dysfunction throughout her service period.
Having a hypothalamic disorder causing excessive eating for at least the 3 months before the clinical onset of obesity - NOT MET No evidence of hypothalamic pathology or neurological disorders affecting appetite regulation.
Inability to sleep for an average of more than 5 hours per night for at least the 5 years before the clinical onset of obesity- MET Military service demands including shift work, deployment sleep disruption, operational tempo, and stress-related insomnia from 2004-2010 created chronic sleep deprivation patterns known to disrupt metabolic hormones and promote weight gain.
Undertaking night shift work on at least 500 occasions within a continuous period of at least the 5 years before the clinical onset of obesity - MET Medical duties required extensive shift work including night duties in medical facilities, deployment rotations with altered sleep cycles, and emergency response callouts disrupting normal circadian rhythms from 2004-2010, easily exceeding 500 occasions over 6 years.
In a person with a prior history of a regular smoking habit, permanently ceasing to smoke within the 2 years before the clinical onset of obesity - NOT MET She quit smoking in 2007 via hypnosis, but obesity onset was documented in 2010, exceeding the 2-year timeframe.
Having consumed a cumulative total of at least 50 kilograms of alcohol from drinking beer within the 5 years before the clinical onset of obesity (RH factor) - NOT MET Her documented alcohol intake patterns from 2004-2010 show periods of heavy drinking but insufficient documentation to confirm 50kg cumulative beer consumption specifically.
Experiencing severe childhood abuse before the clinical onset of obesity - NOT MET No documentation of childhood abuse or trauma in her history.
Physical inactivity due to injury (not in SOP but relevant factor) - MET Right knee chondromalacia patella onset in June 2003, requiring arthroscopy in 2005, significantly limited exercise capacity during the critical period leading to obesity onset in 2010.
Inability to obtain appropriate clinical management for obesity - MET Military healthcare system lacked specialized obesity management programs, competing operational demands prevented consistent lifestyle interventions, limited access to dietitians and weight management specialists, and cultural stigma around weight issues in military environment created substantial barriers to appropriate clinical management per Brew v Repatriation Commission precedent, causing permanent worsening through progression to Class II obesity.
Sequelae
Obesity contributed to development of multiple secondary conditions including hepatic steatosis, gallbladder polyps, hyperlipidemia, and exacerbated existing musculoskeletal conditions through increased joint loading, creating a cycle of reduced mobility and further weight gain.
Unintended Consequence
No evidence that obesity resulted from unintended consequences of ADF medical treatment.
Inability to Attain Appropriate Medical Management
MET - As referenced in Brew v Repatriation Commission (20 May 1996), inability encompasses both objective and subjective barriers to treatment. Military healthcare focused on acute rather than chronic disease management, with no specialized obesity services available during her service period. Competing operational demands prevented consistent participation in weight management programs. Limited access to registered dietitians, endocrinologists, or bariatric specialists. Military culture stigma around weight issues created psychological barriers to seeking comprehensive treatment. The 6-year period from weight gain onset (2004) to formal recognition (2010) demonstrates systematic failure to provide appropriate preventive and therapeutic interventions, causing permanent worsening through progression from overweight to Class II obesity before eventual self-directed improvement.
The % contribution of the causes is 100% and significant.
