Also, laparoscopic surgery is considered to be equally effective as the open surgery, being equally safe as well.

Alternatively, a blood clot may appear in the lung, leading to a pulmonary embolism. Some other condition which are quite common in people who have undergone gastric bypass surgery recently are appearance of gallstones or anemia, as well as osteoporosis.
Nevertheless, after the Roux-en-Y gastric bypasses, more than 30% of all patients develop iron and vitamin B6 deficiency. Out of all these people, 50% end up with anemia. Also, up to 15% of patients end up with ulcers or experience loosening of the staples.

Not doing this may result in vomiting and pain. Furthermore, you are advised not to drink anything about half an hour before consuming food and half an hour afterwards. Ultimately, you will need to stay away from certain types of food such as candy, simple sugars, juices, ice-cream and soft drinks. Simple sugars can be quite dangerous for you to consume, possibly leading to a condition named dumping syndrome, triggering sweating, dizziness, rapid heart rate and severe diarrhea.To sum up, gastric bypass is a surgery which decreases the size of one's stomach, dividing it into two smaller parts, thereby limiting one's stomach capacity. This results in a decrease in appetite and food consumption, helping morbidly obese people to deal with their excessive body weight and the conditions which go hand-in-hand with it.
