Liver (Definition)

This organ plays a major role in metabolism and has a number of functions in the body, including glycogen storage, decomposition of red blood cells, plasma protein synthesis, hormone production, and detoxification. It lies below the diaphragm in the abdominal-pelvic region of the abdomen. It produces bile, an alkaline compound which aids in digestion via the emulsification of ...Read more

Since the gastric sleeve can cause complication with a sarcoidosis patient. Is the gastric bypass better to have done with sarcoidosis?

Since the gastric sleeve can cause complication with a sarcoidosis patient. Is the gastric bypass better to have done with sarcoidosis?

Sleeve ; sarcoidosis: Neither one (bypass or sleeve) is better than the other with respect to sarcoidosis. Studies have shown that people on immunosuppressive therapy can safely undergo either operation. I would just decide which operation is best for you. In a healthy ; moderately obese person, either operation is fine. If you have gerd, diabetes, or have a bmi over 50, bypass is preferred. ...Read more

Can a hiatal hernia be caused by gastric bypass?

Can a hiatal hernia be caused by gastric bypass?

Typically not.: Typically, having gastric bypass surgery would not cause a hiatal hernia, however, obesity could. The hiatus is a natural opening in the body. Being overweight naturally stretches at this opening, causing the opening to enlarge and eventually becoming a hernia. Like taking a styrofoam cup and sticking a pencil thru it and start turning the pencil. The hole gets bigger and bigger. ...Read more

My veins are really dark and show through out my whole body. Could this be a cause for concern? Have had bad health since gastric bypass surgery!

My veins are really dark and show through out my whole body. Could this be a cause for concern? Have had bad health since gastric bypass surgery!

Weight loss: The veins may be more visible from the weight loss. The benefits of the weight loss however far outweigh the risks of the excess weight. It depends of course how much weight you've lost, when you had the bypass, and your medical conditions. I would suggest you call your surgeon for a follow-up evaluation and see if they have any suggestions. Hope this helps! ...Read more

My legs are bowing. I had gastric bypass surgery 10 years ago. Could this be the cause.

My legs are bowing. I had gastric bypass surgery 10 years ago. Could this be the cause.

No: Bowing of your legs is due, most likely, to arthritis, not to the gastric surgery. Increased weight can cause increased joint wear and changes in your mechanical axis. The weight reduction likely is currently reducing your symptoms, but arthritis and mechanical axis malalignment is common in the general population in your age group. ...Read more

I am a 28yo woman, 2yr. Post op gastric bypass. I am often nauseas & go days vomiting keeping. Only liquids down. What could be the cause? Dr says im fine

Possible stricture: If the nausea and vomiting have been occuring since surgery it may be your gastric pouch was made to small. If the symptoms are more recent, there is the possibility of an anastomotic stricture or marginal ulceration. Evaluation of the bypass anatomy with an upper endoscopy or an UGI study would be appropriate. ...Read more

After having gastric bypass surgery in December of 2016, I now have a hiatal hernia. Could this be the cause of slow weight loss?

Possible reflux: Many gastric bypass patients experience alteration in GI emptying due to their new surgical connections. When ingested food then regurgitates or refluxes, burning or chest discomfort may result. Talk to your physicians about whether an acid blocker medicine should be tried or further investigation is warranted. Typically, uncomplicated hiatal hernias do not alter efforts at weight loss however. ...Read more

Had Gastric Bypass. Always been a slow loser. On Prozac (fluoxetine). Can Prozac (fluoxetine) cause me to lose weight slower than those not on it who had weight loss surgery?

Could be.: Prozac (fluoxetine) could cause weight gain all by itself. Perhaps it's thwarting your efforts. Contrave is a weight loss pill that contains an anti depressant (WellButrin) - might be a good choice to switch to from Prozac (fluoxetine). ...Read more

I had small sliding hiatal hernia 4/12. 3/27/13 I was hit from behind in car accident with seatbelt on 4/2/13 had gastric bypass surgery; found large paraesophageal hernia. Can the accident cause this?

It is possible: It is possible, but difficult to know 100%. It would be helpful to know how large the hernia was at the time if you gastric bypass, something your surgeon would know. You should see your surgeon anyway to help guide you on what to do about the paraesophageal hernia. Hope this helps! ...Read more

Had Gastric Bypass. EGD clear. Ultrasound shows sludge in gallbladder. Can sludge still cause me pain in my right side and extreme nausea after eating?

Had Gastric Bypass. EGD clear. Ultrasound shows sludge in gallbladder. Can sludge still cause me pain in my right side and extreme nausea after eating?

Possibly.: Usually sludge in the gallbladder doesn't cause pain (gallstones can). However, it may be that your gallbladder isn't functioning properly. The best test to have done is a HIDA with cholecystokinin (a special nuclear medicine test that tells whether the gallbladder empties properly). Your primary care doctor can order this, or your surgeon. If positive, taking the gallbladder out can help. ...Read more

Lack of what vitamins can cause cracked lips? Since I had gastric bypass (5 yrs ago), my lips have been chronically cracked. It's really bad. I take all my vitamins. Labs ok. Do I need more vitamins?

Lack of what vitamins can cause cracked lips? Since I had gastric bypass (5 yrs ago), my lips have been chronically cracked. It's really bad. I take all my vitamins. Labs ok. Do I need more vitamins?

May be food allergy: Riboflavin (b2), zinc, or iron deficiency can cause cheilosis (cracked corners of mouth), so it may help to take higher doses of these due to possible absorption problems. Check with your doc. In addition to what's been said, you could have a chronic food allergy causing your cracked lips. Common causes include gluten/gliadin (wheat), dairy, soy, and eggs. An elimination diet may help. ...Read more

Gastric bypass with hiatal hernia repair done wed-off painkillers-vomiting (no nausea) a fecal like material-more coming out then going in-cause?

See your surgeon: The cause could be something normal during the post-op healing from a bypass, but it could also represent a problem. If you are not able to keep yourself hydrated, then you need IV fluids and medical attention. I definitely recommend contacting your bariatric surgeon for further evaluation. ...Read more

Diagnosed me with bile induced gastritis. Wants to do a gastric bypass. In my 40's, (5'4", 203), but isn't there a less invasive answer?

Diagnosed me with bile induced gastritis. Wants to do a gastric bypass. In my 40's, (5'4", 203), but isn't there a less invasive answer?

Options: Probably theist popular weight loss operation at the moment is a sleeve gastrectomy. Its not really less invasive, but has less potential for long term side effects. There are also some newer endoscopic therapies, but they are not so effective. Ask your doctor if a consultation with a Bariatric surgeon is appropriate. Hope this helps! ...Read more

Can you eat a bagle after gastric bypass?

Bread is hard: To eat after any weight loss surgery unless it is toasted and crunchy. The doughy breads get stuck and do not go away quickly. Toasted breads with "melt" with saliva and, if it gets stuck, will eventually go away. Avoid raw bread, toast it. Really should limit bread intake though. Focus on hard, solid protein like fish and chicken. ...Read more

Is the mini gastric bypass safe or better than the?

Is the mini gastric bypass safe or better than the?

Mini gastric bypass: The mini gastric bypass is not endorsed by any asmbs or any of the top academic bariatric surgery programs in the country. It is safe, but it is basically a billroth 2 operation which can cause bile reflux. The fix for that problem is a roux-en-y gastric bypass meaning that for 50 years we have known that a roux-en-y is better than a billroth 2. The b2 is just easier for the surgeon to do. ...Read more

What are some good eating patterns after a gastric bypass?

Gastric bypass diet: Ideally, a gastric bypass patient should be able to eat "normal food" long term. However, you should minimize the amount of carbohydrate (bread, rice, pasta) that you eat, and eat more protein and vegetables. You should also avoid foods with a high sugar content as this can cause both weight gain and dumping syndrome. Basically just healthy eating. ...Read more

Could you tell me what happens ten years after a gastric bypass?

10yrs after bypass: Hopefully nothing. We hope that your bypass anatomy stays the same and that you maintain your weight loss. People can regain weight if they overeat, eat junk food, or don't exercise. You have to constantly work at it. Sometimes the weight gain is due to stretching of the pouch or anastomosis or both. In general though, people do fine 10 years out from surgery. ...Read more

What is the likelihood of death and complications of gastric bypass?

Gastric bypass risk: It depends on where you have surgery. Nationwide, the risk of death is about 1/500 to 1/1000 operations. However, if you go to a highly specialized center with a long track record, the risk can be much less than that. A bypass is a fairly difficult operation, whereas a lap band is very easy. I would only trust my associate and a handful of colleagues to do a bypass on myself or a relative. ...Read more
