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 come digestive enzymes are reduced after gastric bypass surgery?

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

How the high fat diet and low fiber diet considered as a risk factor of colorectal cancer ?

How the high fat diet and low fiber diet considered as a risk factor of colorectal cancer ?

Controversial: Various studies have yielded various results, as is common in epidemiology. It may still be "politically correct" to blame meat-eating, low-fiber, high-fat diets for colon cancer, but you also need to know that the hard-core studies have generally shown less of an effect than you may have been told. Don't forego screening -- no one's immune. ...Read more

Some people experience palps after eating heavy meals that are rich in carb, sugar, fat, high level of MSG, nitrates & sodium (webmd.com). Why could?

Multiple responses: Carbs and sugar effect changes in insulin and blood sugar levels which, when abnormal, can cause palpitations. SMG and sodium causes salt and fluid retention, high blood pressure and heart failure with palpitations. Nitrates cause asthma and allergies in some. I'm not aware of fat causing immediate palpitations. ...Read more
