Bariatric Care Flashcards
(37 cards)
What is overweight and obesity defined as
abnormal or excessive fat accumulation that may impair health.
What is a bariatric person
an individual of any age (child to adult) who has limitations in health and social care due to physical size, health, mobility and environmental access.
What is BMI defined as
as weight in kilograms divided by the square of the height in meters.
BMI provides the most useful population-level measure as it is inexpensive, easy to use, the same for both sexes and for all ages of adults.
What are limitations of BMI
Does not assess body fat distribution, because it is a measure of excess weight rather than excess body fat.
Does not account for factors such as age, sex, ethnicity, and muscle mass.
What is the fundamental cause of obesity
energy imbalance between calories consumed and calories expended.
What factors play a significant role in obesity
genetics, socioeconomic status, environment and individual decisions
What are contributing factors to obesity
Underlying health problems e.g. hypothyroidism in Down’s syndrome and eating issues such as Prader-Willi syndrome
A lack of energy
Difficulty with chewing or swallowing food or its taste or texture
Medications that can contribute to weight gain and changes to appetite e.g. steroid medication
Physical limitations that can reduce a person’s ability to exercise pain on movement (e.g. in cerebral palsy, rheumatoid arthritis
Lifestyle Factors: A lack of healthy food choices; Accessible environments that enable exercise; Resources and appropriate social support systems
Is obesity a disability
not by equality act but conditions associated with obesity may lead to disability
Failure to provide suitable safe facilities for bariatric patients has the potential to breach the Equality Act (2010)
What is expected from dental professionals regarding adjustment
Those with disabilities should have the same access to health care as anyone else and it is the responsibility of health care professionals to make reasonable adjustments to aid universal access to our services.
What is the role of the dental team regarding obesity
Identify oral health issues associated with the bariatric patient.
Signpost patients to appropriate services e.g Weight management.
Be aware of comorbidities or predisposition to dental disease.
Appropriate referral onto Secondary and Tertiary care.
May have to provide emergency care prior to onward referral.
Raise concerns with patient, parents or carers of vulnerable adults and children.
What should be considered prior to the appointment
Ensure your venue has appropriate facilities for patient care.
This may involve telephoning the patient/referrer/carer prior to initial visit querying: Patient Weight or BMI, Mobility e.g. do they use a wheelchair? Manual or motorised?
What should be considered regarding travel
Is the patient taking private transport e.g car / taxi? Parking should be available as close to the venue as possible.
Ambulance transport - will only take patients to Hospitals
What should be considered regarding accessibility
Waiting room with suitable high weight bearing armless chair.
Adequate door widths
Toilet facilities accessible
Is the practice accessible via lift or stairs
Emergency Evacuation procedures
Under no circumstances should staff attempt to break the fall of an obese patient
What should be considered regarding the timing
May require longer appointment times due to reduced mobility
Extra weight around the face can obstruct the access to the mouth
What should be considered regarding safety
Specialist equipment may mean patients need referral tospecialist clinics or hospitals
Wider cuff blood pressure monitors.(e.g. “thigh cuff”); Longer IM needles are needed.
May be unable to get patient rapidly into supine/recovery position or physically move patient.
Airway management may be more difficult.
Resuscitation – identification of landmarks for chest compressions may be difficult
What should be considered regarding the chair
If the patient does not know their weight and is perceived to exceed 22 stone/140kg an accurate weight must be obtained through weighing the patient.
Unfortunately most standard weighing scales only weigh up to 22 stone.
What are people who carry weight in upper body and chest at risk of
hypoxaemia when lying flat.
In extreme circumstances some may present with obesity hypoventilation syndrome - this is a result of chronic hypoventilation due to the prevention of full expansion of the lungs.
What are comorbidies of obesity
Hypertension and CVA. Diabetes Sleep apnoea (may use a CPAP machine) Dyspnoea Gastro oesophageal reflux disease (GORD) Osteoarthritis Depression/anxiety Liver and gallbladder disease Skin conditions such as cellulitis and intertrigo
Why does obesity make tx difficult
Loss of anatomical landmarks is possible. There are access problems with large cheeks, tongue etc.
ID blocks may be difficult. Alternative techniques may need to be considered such as the Gow-Gates or intraligamentary techniques.
May have to be treated semi-supine or sitting upright – practitioners need to be careful with their posture.
Beware operator musculo-skeletal problems when working in a less than ideal position.
How does obesity impact radiographs
Intra-oral radiography can be more challenging due to increased soft tissues.
OPT can be difficult or even impossible if the machine is unable to accommodate the patient’s size.
Long procedures can lead to acute leg oedema, cellulitis, Compartment Syndrome and pressure sores.
Coagulation abnormalities may occur (e.g. due to non-alcoholic fatty liver disease)
Excessive fat in the tissues may also affect pharmacological absorption of a drug
What is compartment syndrome
painfull, bleeding and swelling within enclosed muscles increasing pressure, restricts the blood flow and damages nerves/muscles
What are dental implications of periodontitis
Obesity does not appear to play a negative role in the treatment outcome of non-surgical periodontal therapy.
Diabetic patients have a high associated risk of periodontal disease.
Be aware of the complexity of obesity and be able to discussthe importance of maintaining healthy body weight and performing good oral hygiene procedures.
What are dental implications of obesity
caries
wound healing
tooth wear
What is the impact of obesity on caries
Bariatric patients may have a higher caries rate than general population as causations are interrelated (diet high in processed sugars).
