Gastric bypass is a form of weight loss surgery. It is performed on individuals who are obese and unable to lose weight to maintain a healthy size through any other means, such as diet or exercise. It works by removing a part of the stomach and intestinal tract and redirecting the digestive system to reduce the amount of food that can be ingested. Gastric bypass surgery is a major operation that can cause a variety of problems in patients post-operation, which is why it should only be considered as a last resort.
Minor Problems
There are a number of small problems that an individual can experience in the first six months after gastric bypass surgery. These issues are the results of the significant weight loss that occurs, as well as the decrease in healthy nutrients and the compromised absorption of vitamins and minerals. Some of these small problems include hair loss, mercurial moods, dry skin, sensitivity to cold, chronic fatigue, and muscle aches. However as the body stabilizes post procedure, these small problems should rectify themselves.
Blood Clots
A major problem that an individual can experience after gastric bypass surgery is blood clots in the legs. Blood clots can be very dangerous and lead to heart attack, stroke, and pulmonary embolisms. While blood clots are always a serious risk for individuals who are overweight or obese, they are a particular concern for patients after gastric bypass because of the physical trauma of the surgery as well as the rapid alteration in blood sugar, platelet count, and immune response. Moving legs frequently and getting at least 15 minutes physical exercise using the legs each day can help reduce the risk of this major problem.
Chronic Dehydration
Dehydration is another major problem that occurs after gastric bypass surgery. While dehydration may not seem like a severe issue, chronic dehydration can lead to a variety of other problems, such as electrolyte imbalances, blood sugar imbalances, and digestive stagnation. Individuals who get gastric bypass surgery are at greater risk for chronic dehydration due to the fact that a large portion of the stomach and intestine, the main organs which absorb water, have been removed.
Dumping Syndrome
Dumping syndrome is a condition that arises after bariatric surgery when food and liquid ingested into the reduced stomach do not have a chance to properly digest before reaching the small intestine. The result is chronic vomiting, diarrhea, sweating, and symptoms of fever. Dumping syndrome can be avoided by reducing the amount of high-fat or high sugar foods in the post-operation diet.
Kidney Stones and Gallstones
Kidney stones and gallstones, two types of calcified mineral deposits, are also common problems after gastric bypass surgery. These problems occur due to the lack of hydration, the severe altering of dietary intake, and reduced immune function immediately after surgery. While these complications are not dangerous to health, they can be extremely painful to pass, and may need to be eradicated by a doctor.
