Care during weeks 3–4 after bariatric surgery
Progression from liquids to soft textures should follow your team's instructions; food tolerance, hydration and warning signs are priorities.

Which foods are suitable?
Diet plans differ between centres and procedures. Some allow puréed or soft foods at this stage, but you should not start solids based only on the week number. Follow discharge instructions and your dietitian's advice on texture, portion size and meal frequency.
How should you eat?
Take small bites, eat slowly and chew thoroughly. Stop at the first feeling of fullness or discomfort. Prioritise tolerated protein sources. Follow your team's plan for fluids and their timing around meals; very sugary drinks may cause problems.
What is dumping syndrome?
After some procedures, especially bypass, rapid food entry into the intestine can cause cramps, nausea, diarrhoea, palpitations or dizziness. Later symptoms may relate to low blood sugar. Do not diagnose every episode of weakness or sweating as dumping. Record symptom timing and food intake, and seek assessment for recurring symptoms.
Take vomiting and swallowing problems seriously
Large bites or fast eating can cause discomfort, but persistent vomiting or difficulty swallowing may require investigation for narrowing or another complication. If you cannot keep fluids down, do not wait for dietary changes: contact your surgical team the same day. Dehydration and nutritional deficiencies need early recognition.
Movement and follow-up
Continue short, frequent walks as tolerated. Obtain advice about strenuous activity and driving based on pain, medicines and your team's assessment. Continue prescribed supplements and discuss hydration, protein, bowel movements and previous medicines at follow-up. Severe pain, fever, breathlessness or fainting requires immediate assessment.
