Nutrition and Diet                  

After Bariatric Surgery, we need to follow balanced diet which is rich in protein, low in carbohydrates and low in fats.

Bariatric diet is divided into 3 phases:

Phase I: First 2 weeks after surgery(1-14th day)

Patients are given clear liquids on day 1 after the contrast study 30 ml/hr water only. On day 2, 50-70 ml water or coconut water per hour is given. From day 3rd - 14th, 70 - 100 ml clear liquids per hour as instructed.

Clear Liquid Diet includes:

  • Water
  • Skimmed milk
  • Lemon water
  • Ginger tea
  • Black tea
  • Green tea
  • Coconut water
  • Clear soups
  • Water with added protein powder         

Phase IIDay 15th - Day28th (Next Two Weeks)

In this phase patients are instructed to have semi-solid diet. High intake of protein about 60-80 gm is advised along with 100ml/hour of fluid is given. This semi-solid diet can be divided into six small meals of the day.

Physical Activity:

Your ability to resume pre-surgery levels of activity will vary according to your physical condition, the nature of the activity and the type of bariatric surgery you had. Exercise for bariatric surgery patients is often the first part of patient's long term plan to get skipped following surgery. It is almost as important as your diet.

Behaviour Modifications:

Behaviour plays a significant role in weight management. Modifying behaviours that contributed to developing obesity is one way to heat the disease of obesity either alone or in conjunction with other treatments.

Few behaviour change strategies are:

  • Self - monitoring
  • Increasing physical activity
  • Becoming educated about the body and how to nourish it appropriately.
  • Engaging in a support group
  • Setting realistic goals

Our behaviours are engrained in our daily routines, families, lifestyles and more. It is important to stick with your behavioural changes, as they will greatly help you in your weight loss journey.
