Nutritional ramifications and gastric bypass surgery? What are the nutritional ramifications to gastric bypass surgery? What vitamins can't be absorbed?

There : There are many nutritional changes after bypass surgery and they can vary depending on type of bypass or band. If you are thinking of undergoing bypass surgery be sure that wherever you are thinking of having the procedure preformed there is a nutritionist as they will be an important part of your medical team. Usually, immediately following surgery, there will be strict guidelines for how much and what types of food to eat. These will loosen over time. It is important to remember that you can still gain weight and have your bypass fail if you continue with poor eating habits. While you will feel full after little food you can stretch the pouch. Avoid foods with high fat and sugar content. Remember at first to eat very slowly, stop when full, chew food well, and concentrate on protein and hydration. Over time, months, you will most likely be able to eat all the foods you used to, but much less. Most often people will eat three, small, well chewed meals per day. Because of changes in gastric acidity and the new structuring of the intestine after roux-en-y gastric bypass the absorption of several micronutrients may be affected; b12, calcium, vitamin d, folate, iron, and thiamine to name a few. Your physician will usually do blood tests at 3 months, 6 months, and then yearly to follow lipid levels, iron levels, B12 and folate levels, calcium, vitamin d and parathyroid hormone levels, and your blood count. Most recommend taking a multivitamin with minerals and iron daily, and a B12 supplement (may be oral or injected). If your iron level is low you may be instructed to take a supplement --only do this if your level is low. You may also need additional calcium or vitamin d depending on your lab work. Patients undergoing lap banding may only need a multivitamin. Above all remember to work closely with your doctor and nutritionist. Weight loss surgery takes a lifelong commitment to be successful. ...Read more

How are gastric band operation and gastric bypass different?

How are gastric band operation and gastric bypass different?

Weight loss: The band is placed around the upper part of the stomach to restrict the amount of food you can consume. It is adjustable depending on the amount of food you can eat and weight loss. The bypass permanently changes the anatomy by re-routing the intestines. The sleeve gastrectomy permanently changes the size of the stomach. All work well for the right people. ...Read more

Is the 5 day pouch test ok for  gastric bypass patients ?

Chronic obese pain patient. Medicare and Medicaid. Trying to have gastric sleeve bypass need primary for physician supervised diet. ADrive? Thanks

Gastric sleeve: Hi. We don't have all the information on you (BMI, obesity comorbidities), but you may very well meet criteria for sleeve gastrectomy surgery. It can help a lot with weight loss, and doesn't alter the anatomy of the small intestine, so there is generally not a problem with nutrient malabsorption. And depending on the nature of your chronic pain, it may help with that. What does "ADrive" mean? ...Read more

How are lap band and gastric bypass surgery different?

How are lap band and gastric bypass surgery different?

Malabsorption: The lap band is a device placed to make the stomach seem smaller thus allowing you to eat less and feel satisfied. With the bypass, a surgeon creates a smaller stomach by cutting which has a similar effect. Additionally, the intestines are cut and rerouted so that the upper segment is "bypassed". This decreases the absorption of food which leads to faster and relatively easier weight loss. ...Read more

How effective is the rny gastric bypass surgery?

Depends on behavior: A roux-en-y gastric bypass can be quite effective in weight loss if it is part of a multi-modality treatment process. This can include support, diet, exercise, as well as the surgery. Your doctor can guide you in finding a qualified bariatric program, but you must be willing to accept that such a procedure is not the end, and you will have to actively participate in your recovery. Good luck. ...Read more

How come digestive enzymes are reduced after gastric bypass surgery?

How come digestive enzymes are reduced after gastric bypass surgery?

Loss of physiology: Food normally is mixed with acid and mechanically broken down in the upper stomach. Small amounts are released through the antrum of the stomach, which goes through the duodenum and proximal jejunum. Various substances stimulate secretion of gut hormones and enzymes. In gastric bypass operations, the antrum, duodenum and proximal jejunum are bypassed and reduce levels of these hormones. ...Read more

Do gastric sleeve or gastric bypass work better for losing weight?

Do gastric sleeve or gastric bypass work better for losing weight?

Both similar: The sleeve and bypass work in almost all patients. Our experience is to expect about an 80% excess body weight loss with the bypass and 70% with the sleeve. So if you weigh 250 and you are supposed to weigh 150, then you have an excess weight of 100 lbs. Most patients make their decision based on side effects or risks. Both are great. ...Read more

Can gastric dumping syndrome occur in a person with no prior gastric bypass surgery?

Dumping: No, not really. There are a very small percentage of people that will get post prandial hypoglycemia, but that only gives you some of the symptoms of dumping. With dumping, you can also get diarrhea, a stomach ache, nausea.
