Bariatric Journey

Bariatric Surgery Guidelines for 6 Weeks – 6 Months After Surgery

Hydration

  • By now, drinking fluids should feel much easier than in the early weeks after surgery.
  • Staying properly hydrated is essential for healing, digestion, and energy levels. Aim to drink at least 1.5 to 2 litres of fluids per day.
  • A simple way to check your hydration status is the colour of your urine. It should be pale yellow—if it is dark, you need to drink more water.

Diet: Transitioning to Solid Foods

  • Start introducing solid foods into your diet gradually. Begin with fish, then chicken, and then red meat.
  • Protein-based foods should be the foundation of your long-term diet. Every meal should prioritise protein sources like lean meats, eggs, dairy, tofu, and legumes.
  • Introduce new foods carefully. Start with a small portion of any new food and give your stomach plenty of time to adjust.
  • Limit carbohydrates such as potato, bread, pasta, and rice as they can expand in your stomach, making it harder to consume enough protein.
  • Use the Portion Perfection Plate and Bowl (provided in your pre-op green bag) to help with food selection and portion sizes.
  • Hunger may start to return as your stomach heals. Avoid unnecessary cravings by limiting exposure to food-related TV shows, cooking videos, and advertisements.

Multivitamins and Supplements

  • Continue taking your bariatric multivitamins twice a day—this is essential for preventing vitamin and mineral deficiencies.
  • Many patients switch from chewable vitamins to capsules at this stage. If you find capsules easier to swallow, you can try BN Multi Capsules (formulated for bariatric patients).
  • Some patients may require additional supplements such as Iron, Calcium, Vitamin D, and B12 injections. Your blood tests will help determine if you need these.

Exercise: Building Strength and Stamina

  • From six weeks after surgery, there are no restrictions on activities.
  • Consistency matters—regular, moderate exercise is more effective than intense but infrequent workouts.
  • Aim for at least 20-30 minutes of brisk activity 5 times per week. Walking, swimming, or cycling are excellent options.
  • Strength training (using light weights, resistance bands, or bodyweight exercises) helps rebuild muscle and boosts metabolism.
  • If you still feel fatigued, focus on hydration, protein intake, and gradual increases in activity.

Pain and Gallstones

  • By now, pain should be minimal or completely gone.
  • Some patients who had gallstones before surgery may begin experiencing gallbladder attacks (pain in the upper abdomen and back).
  • By six months post-op, about 20% of patients will develop gallstones due to rapid weight loss. These stones can cause pain if they block the bile duct.
  • If you still have your gallbladder and had no gallstones on your pre-op scan, we will arrange an abdominal ultrasound before your 6-month review to check for new stones.
  • If gallstones become painful, gallbladder removal may be necessary.

Acid Reflux (Heartburn)

  • Continue taking Nexium (or another PPI) daily until at least 3 months post-op.
  • If heartburn persists after 3 months, continue Nexium as needed and discuss with your surgeon if symptoms persist.
  • Over time, as your stomach heals and becomes more flexible, reflux should improve.
  • To prevent acid reflux: Do not eat or drink for at least one hour before bedtime. Avoid spicy, acidic, or fatty foods.

Vomiting

  • Vomiting should not be common at this stage.
  • It may happen if eating or drinking too quickly, or eating too much.
  • To avoid vomiting: Eat slowly, chew food thoroughly, and stop eating at the first sign of feeling full.

Hair Loss After Surgery

  • Temporary hair loss is common during the first year after surgery.
  • This is due to the stress of surgery and rapid weight loss, similar to postpartum hair loss.
  • Hair will regrow fully within 9-12 months.
  • Extra vitamins or protein supplements will not prevent hair loss, but adequate protein intake and multivitamins are essential for overall health.

Tracking Your Weight Loss Progress

  • Weigh yourself only once a week using the same scales, at the same time each week.
  • Taking monthly progress photos can help you see changes that the scale doesn’t reflect.
  • Weight loss is not always linear—some weeks you may not see much change, while other weeks will show bigger drops.

Follow-Up Appointments

  • You will have an appointment with your surgeon, nurse, and dietitian around the 6-8 month mark.
  • Before your appointment: Complete blood tests at least one week prior.
  • If you still have your gallbladder, schedule an upper abdominal ultrasound two weeks before your appointment.
