Define morbid obesity | because of obesiety, can get serious health conditions |
What classifies morbid obesity | 200% ideal body wt, 100lbs overweight, BMI of 40 or more |
Severe RF’s of of medical conditions d/t obesity | DM, gall bladder, HTN, dyslipid, insulin resistence, breathlessness, sleep abneal |
Mod RFs for med conditions | CHD, OA, hyperuricemia and gout |
What are classifications for results of medical therapy in wt loss | 95-98% failure of sustained wt loss at 5 yrs, 100% failrure |
What are options for medical therapy | diet, exerdcise, behavior modifcifation, anti-obesity drugs |
How often does diet and exercise work | 1 in 20 people |
What is A1C goal for DM patients | <6 |
What is the best wt loss strategy in morbitly obese pt’s w/ DM | more invasive, better the results: biliopancreatic > gastric bypass/gastric sleeve >lab band |
Who are the best canidates for surgical tx of DM | Duration <10 years, Insulin resitance (prediabetic), B-cell fxn remaining, BMI overweight/obese |
Who are actual surgical candidates | BMI >40, BMI >35 with co-morbities such as DM II, OSA,HTN, Hyperlipids, CVD, and must be dedicated to life-style changes and F/U care |
What must we check of the surgical candidate | check for endocrine, operative risk, absence drug/alcohol prob, non-smoker, psych conditions controlled |
3 types of surgical options | malabsorbtion: bioliopancreatic, restruction: adjustable gastric banding and sleeve, malabsorptive and restrictive: roux-en-y gastric bypass |
Gold standard and most frequent surgery | roux-enY gastric bypass surgery |
When in wt loss the greatest with Roux-en-Y | greatest in the 1st year |
How does the restriction cause wt loss | small pouch, receptors stretched w/ small amounts of food, ↓ wt |
Risks of gastric bypass | major abd surg,cutting and stapling, rapid wt loss, malabsorption |
Risks with major abd surg | DVT, death, major bleeding, hernia, wound infex, obstruction |
What are complications w/ rapid wt loss | cholelithiasis, Prevented by cholecystectomy at time of surgery or Actigall |
Complications w/ cutting and stapling | leak, stenosis, dumpin syndrome, gastric/duodenal ulcers, N/V/dehydration |
Signs of a leak in the intestines | tachy, pain (jumps from 2-8?), peritoneal signs |
Signs of stenosis of the bowel | N/V, inability to keep solids down |
What is dumping syndrome | w/ ↑ surgars and complex carbs, the jujunum can’t take that causings a rush of fluids to rush to the intestine, makes the pt feel awful, N/V, diarrhea, diaphoresis, flushing |
How do we avoid gastric/duodenal ulcers | avoid NSAIDS in abusers or smokes, use tramadol instead |
4 of the most common vitamin deficiencies w/ this surgery | Iron, Vit B12, Calcium, Vit D |
What other two are potentials for vit def | thiamine, folate |
How do we get these vitamins to be absorbed | make the |
What is the restrictive type of surgery | stomach stapleing (sleeve gastrectomy), limits the amount of food you can eat and hunger is ↓ |
Which surgery is better | biliogastric is better w/ wt loss, but sleeve gastrectomy is better tolerated d/t no dumping syndrome |
Sleeve size post surgery | banana or thin hotdog |
What are major complications of sleeve gastrectomy | leak, bleed, death |
Minor complications of sleeve | worsening GERD/barretts, N/V, structure, Vit. Def (lower) |
2 restrictive surgeries | sleeve gastrectomy, laprascoopic gastric band |
How do we control the band | w/ port connected to the band, saline is inserted to adjust the balloon size of the band and adjust for sxs |
How does band work | makes a 3 oz puch created, patient full faster and stays full longer |
Order of surgical effective ness | gastric bypass, sleeve, band |
Complications of gastric band | surgery: dvt, PE, bleeding, Slippage, band erosion, port problems, foreign object, death (LOW), wt loss problsems: gallstones and GERD |
Do we remove band once ideal wt loss has been achieved | commonly not, d/t ↑ chance to regain wt |
How often do we f/u for band adjustments | ~12x/yr, 1 a month until BMI <30 |
What is the optimal zone of tightness for the band | early and prolonged satiety, eat 1 cup and full, and lost 1-2 lbs/week |
What are signs of too lose | hungry, big meals (>1cup), not loosing wt |
s/s of a band that is too tight | difficulty swallowing, |
what does the diet consist of post surgery | initial 2-4 tbsps of food/meal, goal: 1 c, take 30mins to eat, high protein meals are best, no liquid during meals |
why don’t we want to drink liquids during meals | increase the passage of food |
common sxs post surgery | telogen effluvium, excess skin: exercise and plastic surgery: 2 years out, intertrigo (d/t excess skin), cold |
tx for intertrigo | nystatin and triamcinolone cream prn, cornstarch for excess skin areas |
4 personal challenges faced post op | Fatigue, clothing issue, social issue, mental health |
Vitamin replacements for post op | Calcium + Vit D 3x daily w/ meals, MVI w/ iron, Vit D: 2000 UR daily, B12 |
How do we give B12, when and y | daily SL or monthly injection w/ bypass and sleeve |
How often do we f/u | 6m 1yr, yearly after that |
What is the lab work that should be done at F/U | CBC, vit B12, iron studies, Vit D, PTH (d/t calcium) |
What must we check with excessive vomiting | thyamine levels (takes a week), usually automatically give it |
Complications w/ thiamine def | neurpathy, wernikes encephalopathy |
How do we check calcium absorption | do a yearly DEXA scan for osteoporosis, |
F/U apt | every 3 m for 1st year, yearly later, F/U 1 wk with DM, 6m for ↑cholesterol, |
What must females do 18m post op | 2 forms of Birth control, d/t so many changes in the body |
What do we need to check post surgery | followhealth condition, bloodsugars, 1wk, check cholesterol 6m, TSH, adjust meds,dc meds? |
