“A lot changes after weight loss surgery. Like food, your body doesn’t absorb medication as well,” the experts said after bariatric (weight loss) surgery.
A third of Australians are obese and some of them need surgery to lose weight. However, weight loss surgery can change how medications work.
dr Adelaide’s Teresa Girolamo and Rosemary Allin, both weight loss experts, discuss how Australian prescribers may need to adjust the dosage of some medications after bariatric (weight loss) surgery.
About 100,000 weight loss procedures are performed in Australia each year. Some procedures limit food intake, while others shrink the stomach so you eat less.
“Like food, your body doesn’t absorb medication as well after surgery,” warns Dr. Girolamo.
“If you’re taking mood stabilizers or antidepressants,” the expert said, “you may need to take more to get the same effect.”
“After surgery, you may not be able to take slow-release drugs, either. You may need to crush or convert some tablets to a liquid form to aid in absorption. It’s also important to avoid drugs that attack the stomach lining, like ibuprofen and aspirin,” she adds.
“After weight-loss surgery,” she says, “alcohol is absorbed more quickly and eliminated from the body more slowly. This can affect driving.
“Birth control pills may not be reliable due to reduced absorption, so you should consider other birth control methods.
“You’ll also need to take vitamin and mineral supplements for the rest of your life.”
according to dr Girolamo is positive that if you lose weight you may need less medication for blood pressure, diabetes, pain or depression.
“A lot changes after weight loss surgery. Your doctor, pharmacist, and dietician can help you adjust to the changes,” she adds.
