Updated Nov 13, 2026 ## Key points - Assess mobility with the institution's tool and use lifts or transfer aids; students do not use mechanical lifts without supervision. - Sleep apnoea: the patient uses their own CPAP from the immediate postoperative period, with the head up or semi-sitting. - Oxygen raises saturation but can hide apnoeas and carbon dioxide retention: watch breathing, not only the oximeter. - Mechanical plus drug thromboprophylaxis as ordered, and early walking. - Eat and drink at different times: wait at least 30 minutes after a meal before drinking, and sip slowly. - Dumping: early (within 30 minutes: diarrhoea, bloating, nausea) or late (1–3 hours: light-headedness, tiredness, fast heartbeat). ## What it is Caring for a person with obesity safely starts with respect. Mobility is assessed at the bedside, and lifts and transfer aids are used instead of manual lifting, which injures staff and patients. After bariatric surgery, the main ward risks are breathing problems during sleep (obstructive sleep apnoea, worsened by opioids), blood clots and poor intake. Guidelines recommend that patients use their own CPAP from the immediate postoperative period, a head-up position, opioid-sparing pain relief, early movement and both mechanical and drug thromboprophylaxis. Eating changes for life: small portions, slow chewing and liquids apart from meals. Dumping syndrome, when food passes too fast into the small intestine, can appear after meals. ## What it requires - The safe weight a nurse can lift by hand is lower than for a box, because patients move unexpectedly and have wounds or devices. - A bedside mobility assessment tool recommends the handling equipment: gait belt, slide board, sit-to-stand lift or full-body lift. - Lifelong vitamin and mineral supplements and blood tests are needed after bariatric surgery; thiamine deficiency can appear early with vomiting. - Glucose-lowering medicines often need early adjustment after surgery because glucose improves quickly. ## How it is applied (and why) - Assess mobility on admission and record the handling plan: the right aid prevents injuries to the patient and staff. - Ask about sleep apnoea and home CPAP and make sure the patient has it after surgery: it prevents apnoeas. - Keep the head of the bed up or the patient semi-sitting and watch breathing rate, effort and sleep: apnoea worsens when lying flat. - Watch closely after opioids and report pauses in breathing or drowsiness: opioids increase apnoeas. - Apply the mechanical and drug thromboprophylaxis as ordered and help the patient walk early: clots are a leading risk. - Start fluids and diet in the stages the surgical team sets, and report vomiting or inability to drink. - Check glucose in patients with diabetes: medicine needs often fall after surgery and lows can occur. - Teach eating habits, supplements, wound care, activity limits and the warning signs before discharge. ## In nursing practice - Avoid aspirin and ibuprofen after gastric bypass unless the surgeon approves: they can cause ulcers. - Warning signs after discharge: fever, pain that the medicine does not relieve, trouble breathing, vomiting after eating, new leg swelling, yellow skin. - Vomiting, diarrhoea or poor intake in the first weeks increases the risk of thiamine deficiency: report it. - Lifting is limited for several weeks after surgery as the surgeon advises. ## Common mistakes - Relying on body mechanics alone to lift a patient: evidence shows equipment, not technique, prevents lifting injuries. - Leaving the CPAP in the bag after surgery or keeping the patient lying flat. - Trusting the oximeter alone in a patient on oxygen and opioids. - Teaching the patient to drink with meals or to eat large portions. ## Test yourself Think of the answer, then tap the question to see it. ## A patient with sleep apnoea who uses CPAP at home has just had bariatric surgery. What should the nurse do? Make sure the patient uses their own CPAP from the immediate postoperative period, keep the head up or semi-sitting and watch breathing closely, especially after opioids. ## Why can supplemental oxygen be misleading in these patients? It keeps the saturation up but can hide apnoeas and carbon dioxide retention, so breathing rate, effort and drowsiness must be watched. ## What are early and late dumping? Early dumping appears within 30 minutes of eating with diarrhoea, bloating or nausea. Late dumping appears 1–3 hours after a meal with light-headedness, tiredness or a fast heartbeat. ## How should the patient drink after gastric bypass? Not at the same time as eating: wait at least 30 minutes after a meal, and sip slowly instead of gulping.
