How soon can you expect to see benefits after weight loss surgery?

Mr. Perky asked that after you've had your weight loss surgery, how soon should you expect benefits to become apparent? That's an interesting question and it depends on which benefit we are discussing. If it's weight loss, usually patients see weight loss during the pre-operative diet, so they're a few kilos lighter before they even have the surgery. However after surgery, depending on which operation you have, if you have really bad heartburn and have a gastric bypass, often patients wake up with no heartburn at all. Some patients have sleep apnea or s'more very loudly before surgery and this impairs their oxygenation and their ability to stay awake during the day. For patients like that and patients who use CPAP machines at home, often they see an improvement within days or even just a few weeks after surgery. Diabetes patients who are on insulin, especially if they are on large doses, often go home on much smaller doses, or no insulin at all. So there are short, medium, and long-term beneficial effects of the bariatric surgery, which all patients experience at different times, depending on the personalized patient journey. Thank you.
