The benefits of bariatric surgery are undeniable, but the transition to life after the procedure can come with numerous side effects.\nNot only is nausea uncomfortable, but it can also interfere with adequate intake of fluid and electrolyte balance, resulting in more severe side effects.\nBelow is a review of common causes of nausea and tips on how to lessen this side effect of bariatric surgery.\nWhat This Article Covers:\n\nCommon Causes of Nausea\nWill Nausea Improve with Time?\nWhat if Nausea Persists?\n\nCommon Causes of Nausea\nAnesthetic and Surgery\nImmediately after surgery, it is common to experience nausea and even vomiting. There are several causes of this after surgery.\nSide effects from medication and sedation, as well as the anesthetic itself, can make you feel queasy, as can post-operative pain.\nIt is important that nausea does not progress to vomiting and possible damage to the surgery site. Your surgeon is likely to prescribe multiple medications to help prevent it.\nInitial nausea should not last longer than a couple of days after surgery.\nMedication and Vitamin Supplements\nSome medications can cause nausea when taken on an empty stomach.\nThe changes in stomach acid can affect the rate at which vitamins and medications are absorbed, resulting in irritation of the stomach lining.\nTaking your medications with meals or trying different forms of supplements, for example, liquid supplements or chewable bariatric vitamins, may help prevent nausea after gastric sleeve surgery.\nDrinking\nDehydration after bariatric surgery is a potential risk.\nYou must keep in mind that your stomach size is significantly reduced and can be easily overfilled. Drinking too fast or drinking while eating food can put pressure on the new stomach pouch and lead to nausea.\nMost healthcare providers recommend pacing yourself and waiting at least 30 minutes after a meal before having a drink.\nAdvancing Stages Too Soon\nMany people are tempted to consume solid food too soon after weight loss surgery.\nThere is a good reason that reintroducing food in stages of quantity and texture is recommended.\nAdjusting to a new way of eating takes patience, but rushing to eat solid food will result in difficulty processing the food and cause nausea. \nDumping Syndrome\n\nDumping syndrome is a condition that can develop after bariatric surgery when food moves from the stomach into the small intestine too quickly. \nThis unpleasant side effect can happen within minutes of eating a meal or even hours after. \nSigns of dumping syndrome include abdominal fullness, cramping, nausea, sweating, and dizziness.\nConsuming high sugar foods is the biggest culprit, so stick to eating guidelines that your medical team provides you. \nFood Intolerances\nTemporary food intolerances can develop after gastric bypass surgery; the changes in acidity, enzymes, and hormones involved in digestion need time to normalize.\nFood intolerances differ from person to person, but research has found that non-essential high sugar and high-fat foods cause the most trouble resulting in nausea.\nTry small amounts of individual foods at a time. This will help you determine which foods are problematic.\nEating Too Quickly\nEating too fast increases the chance of nausea. \nThe general recommendation is to eat slowly, taking at least 30 minutes to eat a meal. Of course, this depends on what is being consumed and how far out from surgery you are. \nEating with smaller utensils serves as a reminder to take your time and can slow eating.\nChewing Food\nIt is required to chew thoroughly to a paste consistency after bariatric surgery. Chewing cannot be emphasized enough after bariatric surgery. \nProper chewing gives the stomach time to message the brain that it is full and prevents large pieces of food from getting stuck.\nOvereating\nInitially, it may be difficult to gauge how much food you can eat at one time.\nOvereating is one of the most common causes of nausea after surgery. Measuring out portion sizes when you prepare meals is essential.\nIf you are not sure of portion sizes, consult your dietitian for guidance. \nLying Down Too Soon After a Meal\nAcid reflux or burping after bariatric surgery can be worsened by lying down too soon after a meal. This increases the chance of feeling nauseous. \nGive your food a chance to digest and wait at least an hour after a meal before lying down. \nObstruction\nAbdominal surgery can result in scarring in the abdominal cavity. This scarring is called adhesions and can cause twisting of the intestine and blockage. \nA blockage is a rare side effect, but it can occur even years after surgery. Nausea and abdominal pain can be common symptoms. \nFrequent nausea and vomiting should always be reported to your doctor. \nUlcers\nSome patients may develop stomach ulcers after bariatric surgery. These can commonly form at the new connection between the new stomach and the small intestine. \nSmoking and taking aspirin or anti-inflammatory medication will increase your risk of developing ulcers. \nStricture\nA stricture occurs when scar tissue develops at the joint of the new stomach and small intestine, making the opening smaller than it should be. \nA stricture obstructs the passage of food and can cause nausea and vomiting. Stricture is a bariatric surgery long-term side effect, but it can be corrected by your surgeon dilating the connection with a special balloon catheter.\nWill Nausea Improve With Time?\nHealing from gastric sleeve surgery takes time and patience.\n\nAs you understand your new dietary needs and get used to new eating habits, issues with nausea will subside. \nMany causes of nausea following bariatric surgery can be avoided if you diligently adhere to guidelines the surgeon provides you. \nWhat if Nausea Persists?\nRecurring nausea months, or even years, after gastric bypass is uncommon, but can occur. Always consult your bariatric surgeon or doctor so they can investigate. This will rule out any serious health issues that might be causing nausea. \nBottom Line\nExperiencing nausea is common after weight loss surgery, but largely preventable by following your surgeons’ guidelines. \nBe mindful of what and how you eat, get adequate rest, and address stress and anxiety. Psychological stress can cause nausea too.\nPlease keep in mind that these are just a few tips on the causes and prevention of nausea.\nIf you do experience persistent nausea, pain, or uncommon side effects, contact your healthcare provider immediately. \nDid you find our blog helpful?
