Complications of gastric bypass surgery
Nutritional effects
Vitamins
Vitamins are usually contained in the foods we eat, and any additions we decide to take. Amount of food that you eat after gastric bypass surgery is severely reduced, and the vitamin is correspondingly decreased. Supplements to be taken to cover the daily minimum requirement of all vitamins and minerals. Pre-Natal vitamins, are sometimes advised by the doctors, because they contain more vitamins as compare to regular multi-vitamins. Absorption of most of the vitamins are not materially affected after proximal gastric bypass surgery, although vitamin B12 could not be absorbed well by some people. Preparations for sublingual absorption of vitamin B12 is adequate.
The post operative patient was eating the ice due to deficiency of iron after gastric bypass weight loss surgery. Low iron and hemoglobin are more common in patients undergoing gastric bypass surgery. Pica is very common in gastric bypass weight loss surgery patients who have had a condition before surgery ......... read more

Minerals
In all versions of the gastric bypass surgery ,bypass the duodenum, which is the major site of absorption of iron and calcium. Iron replacement is necessary in menstruating women, and supplementation of iron and calcium is preferable in all patients. Ferrous sulfate is not tolerated very well. Other forms of iron (fumarate, gluconate, chelates) are less irritating and having better absorption .Preparations of Calcium carbonate should be avoided as calcium citrate or gluconate, 1200 mg of calcium, has high bioavailability independent of acid in stomach, and probably is better absorbed. chewable supplements of calcium such as vitamin K are sometimes advised by surgeons as a best way to get good level of calcium.
Alcohol Metabolism
A research study that confirmed , after surgery of gastric bypass patients absorbs alcohol more quickly as compare to those who did not undergo surgery. He will also hold a postoperative patient to levels sober after drinking alcohol than those who did not undergo surgery. A study performed on 36 patients after gastric bypass surgery and a control group of 36 people who did not undergo surgery. Each subject received a 5-ounce glass of red wine and alcohol in their breath was measured to assess their alcohol metabolism. The group of gastric bypass had a mean maximum blood alcohol level of 0.08 percent. The control group had a mean maximum blood alcohol level of 0.05 percent. On average, it took 108 minutes in patients of gastric bypass group to return to a zero breath stomach, while the control group had an average of 72 minutes to return to a breathalyzer test to zero.Pica
A study that confirmed the development of pica following gastric bypass surgery due to deficiency of iron . Pica is a compulsive tendency for eating substances other than ordinary foods. Examples would be people who eat the paper, clay, plaster, ash or ice. The study conducted in women after gastric bypass surgery, the patient was consuming 32 ounces of ice eight to ten glasses a day. Blood test showed the patient's iron levels 2.3 mmol / l, the hemoglobin level is 5.83 mmol / L. Patient was then given iron supplements that has led to the hemoglobin in the blood and iron to normal levels. After a month the patient eats reduced by two or three glasses a day. After a year of supplements the patient's iron and hemoglobin levels remained normal and patient reported that she have no desire of ice.
