After major abdominal surgery, some patients pass gas and even have bowel movements, yet eating remains stuck. Attempts to move from clear liquids to soft food to regular meals end in vomiting and a return to fasting. For families keeping watch, this cycle is heartbreaking. After an extensive operation — such as removal of a retroperitoneal sarcoma along with a kidney, adrenal gland, and part of the bowel — it is not unusual for most of the recovery to move quickly while eating lags far behind.
Passing gas and stool is a welcome sign that the gut's major activity has restarted. But it does not automatically mean the stomach is ready to hold and digest food. Surgical handling of the intestines, anesthesia, and pain medicines together can leave the stomach and small bowel sluggish for a time — a state called postoperative ileus, or delayed stomach emptying known as gastroparesis (위마비). In this state, thin liquids may be tolerated, but thicker or textured food overwhelms a stomach that cannot empty quickly enough, and it comes back up.
The foundation of recovery is not rushing the stages. Rather than a large meal, offer very small amounts often, starting with gentle forms like clear broth. Keeping the upper body upright for about 30 minutes after eating helps the stomach empty. After vomiting, it is better to rest the stomach briefly and restart with a sip of water than to push food again right away.
Still, repeated vomiting can lead to dehydration, poor nutrition, and electrolyte imbalance, so it should not be ignored. Being observed in the emergency room or admitted, as is happening now, is a safe choice. The care team may decompress the stomach with a nasogastric tube, support strength with IV fluids or intravenous nutrition, and consider medicines that aid emptying or imaging to check for a blockage. Recovery time varies widely by person and by how extensive the surgery was — from days to weeks — so slow progress does not mean something is going wrong.
What family can do is note the amount and type of each meal and when vomiting occurred, share it during rounds, and set aside the pressure of 'just one more spoonful today.' As hard as it is to watch someone lose weight, remember this is a time to wait for the body to be ready again rather than to force food in.
