Ingestion of proteins after surgery

Proteins are a fundamental nutrient for our body and are especially important for our muscles to form and function properly.
After surgery, it may be more difficult to ingest the sufficient amount of protein we need, so it will be important to include several servings of these food groups in our daily diet:

Ingestion of liquids after surgery

  • It is very important to ensure adequate fluid intake after surgery.
  • The usual recommendation is 1,500-2,000 ml/day, which translates into 8-10 glasses/day.
  • Fluid intake should always be outside the main meals, at least 15 minutes before and after them.
  • The recommended beverage is water, cold or in infusions.
  • Carbonated beverages, sweetened drinks, those containing caffeine (cola, coffee, etc.) and alcoholic beverages (including wine and beer) are to be avoided.

What is dumping and how can it be avoided?

This is a very rapid emptying of the stomach that can cause nausea, vomiting, diarrhea, abdominal pain, dizziness, sweating, etc.

It is produced by the new situation of the digestive system after bariatric surgery and occurs especially when we ingest foods rich in sugars (sugary drinks, juices, sweets, etc.).

To avoid this, we provide you with some simple tips to perform on a daily basis:

  • Limit the intake of foods rich in sugars (juices, sweets, soft drinks, etc.).
  • Whenever possible, select whole-grain bread, pasta and rice.
  • Do not drink liquids during meals.
  • Eat 5-6 meals throughout the day, to ensure that portion sizes are small.
  • Eat slowly, chewing food well, and rest (sitting down) after eating for at least 15 minutes.

Practice of physical exercise

In the initial weeks, the most recommended activity is to go for a daily walk for 20-30 minutes and, progressively, to increase until reaching 1 hour a day. It is important to include strength exercises in the daily routine to avoid losing muscle mass (squats, push-ups against the wall, etc.).

After three months, and if your doctor deems it appropriate, more activities can be included, such as swimming, dance classes, pilates, yoga, etc. Without forgetting to follow the routine of strength exercises and daily walking.
