Post-operative Nutrition Care following Abdominal Surgery

After any abdominal surgery involving the stomach or intestine, the gastro-intestinal function will be affected.  This means the process of food digestion, nutrient absorption or waste removal by passing motion will be disturbed and may stop working for a while.  It may take a few days for the gut to start working again after the surgery so you need to prepare yourself to eat more efficiently.  If you do not eat a balanced diet after surgery, you may become malnourished and your healing process will be affected giving rise to potential complications.

Common Gastro-Intestinal symptoms after Surgery

1. Altered bowel habit will occur for between a few months after surgery with symptoms such as constipation or diarrhoea.  Your gut will produce a lot of gas and passing wind (farting) is a good sign.  There may be ‘good and bad days’ as the bowel gradually heals to regain normal function.  Other symptoms include;

  • Bloated sensation
  • Excess wind
  • Abdominal cramps
  • Nausea or vomiting
  • Bowel obstruction

2. Dehydration may occur because you may not feel like eating or drinking immediately after surgery.  The urine output will be reduced and your urine will look darker.

3. Difficulty to cough after surgery may in retention of phlegm in your lung or throat. 

After your surgery, it is a good idea to have a dietician / nutritionist help your recovery journey to reduce the effects caused by the surgery

Nutrition Principles

  • In the first few days after the surgery, you may want to try blended, pureed or soft diet
  • When you move on to solid foods, try to chew your food slowly and thoroughly because it makes it easier for your body to digest.  As a rule of thumb, chew around 20 times before swallowing
  • Eat meals at regular intervals but more frequently such as 5-6 small meals a day (rather than 3 large meals).  It is easier for your stomach and intestine to digest and absorb the food in smaller quantities
  • Choose foods which are high in nutrients, protein and calories but low in sugar
  • Drink at least 8 cups of fluid every day and this includes liquid foods like soups and yoghurt.  Avoid alcohol, highly sugared or carbonated drinks for the first month
  • If you experience some food sensitivities, avoid it for a while and wait until you are stronger before you try it again
  • Keep a food diary to share with your dietician
