After Surgery

The First 24-48 Hours After Surgery

The first hours following bariatric surgery are a critical period during which the patient is closely monitored. During this time:

• The patient is observed in the recovery room before being transferred to the ward
• Intravenous fluid therapy is administered
• Pain relievers are given regularly
• Blood pressure, pulse, and oxygen levels are continuously monitored
• Anti-nausea medications are used
• Early mobilization is encouraged

The patient is encouraged to move in bed within the first 4-6 hours and shortly afterward to sit at the edge of the bed and stand up with assistance. Early mobilization reduces the risk of blood clots in the leg veins and supports faster recovery of bowel function.

Hospital Stay

The hospital stay varies depending on the type of surgery:

• Gastric sleeve: 3-4 days
• Gastric bypass: 4-5 days
• Mini gastric bypass: 4-5 days
• Revisional surgery: 5-7 days

Leak Test

On the 1st or 2nd day after surgery, a leak test is performed to evaluate the integrity of the gastrointestinal anastomosis. The patient is given a dyed liquid to drink, or an endoscopic check is performed. Once this test is passed successfully, liquid nutrition begins.

Hospital Discharge

Before discharge, the patient receives a written nutrition plan, list of medications, important precautions, and follow-up appointments. Information is also provided about wound care and injections (if applicable).

Post-Operative Nutrition Stages

Post-operative nutrition follows a gradual transition. Each stage is designed to allow the stomach and digestive system to adapt to its new anatomy.

Stage 1: Clear Liquids (Week 1)

For the first 7-10 days after hospital discharge, only clear liquids are consumed:

• Water
• Sugar-free tea and herbal teas
• Clear meat or chicken broth
• Sugar-free, diluted apple juice
• Sugar-free gelatin desserts

Key rules: sip slowly, avoid carbonated drinks and caffeine, and consume at least 1.5 liters of fluid daily.

Stage 2: Full Liquids (Week 2)

Foods that can be added during the second week include:

• Low-fat dairy products
• High-protein shakes
• Strained yogurt
• Smooth, creamy soups
• Sugar-free liquid protein supplements

The daily protein goal during this period is 60-80 grams.

Stage 3: Puréed Foods (Weeks 3-4)

At this stage, all foods must be blended or finely mashed:

• Cottage cheese
• Boiled and mashed egg whites
• Minced meat dishes in puréed form
• Smoothly puréed vegetables
• Puréed fish or chicken

Stage 4: Soft Solid Foods (Weeks 5-6)

Transition to soft, well-cooked foods:

• Boiled eggs
• Soft cheeses
• Steamed fish
• Tender chicken
• Well-cooked vegetables
• Soft fruits (bananas, ripe peaches)

Stage 5: Normal Diet (Week 6 and Beyond)

From week 6 onward, most foods can gradually be added back into the diet. However, the following rules apply for life:

• Eating slowly and chewing thoroughly
• Small portions (typically 100-200 grams)
• Avoiding fluid intake with meals (30 minutes before and after)
• Protein-first eating
• Avoiding sugar, fat, and processed foods

Hydration and Fluid Intake

Dehydration is one of the most significant risks after bariatric surgery. Since the stomach is smaller, large amounts of fluid cannot be consumed at once. Therefore:

• Water should be sipped slowly throughout the day
• At least 1.5-2 liters of fluid should be consumed daily
• Fluid intake during meals should be limited
• Carbonated, caffeinated, and sugary drinks should be avoided
• Alcohol should be avoided for a long time

If symptoms of dehydration (headache, weakness, dark urine, dry mouth) occur, a physician should be consulted.

Vitamin and Mineral Supplements

Due to reduced nutrient absorption after bariatric surgery, vitamin and mineral supplements must be used for life. Recommended supplements include:

• Multivitamin: Taken daily
• Vitamin B12: Monthly injection or daily sublingual tablet
• Vitamin D: Generally 2000-3000 IU daily
• Calcium: 1200-1500 mg daily (citrate form preferred)
• Iron: Especially important for female patients
• Folic acid, zinc, B1 (thiamine): Added based on deficiencies

Regular blood tests are conducted, and the supplementation plan is updated based on identified deficiencies.

Physical Activity

Physical activity is gradually increased after surgery:

Week 1

• Short walks several times a day
• Breathing exercises
• Light leg movements in bed

Weeks 2-4

• 20-30 minutes of daily walking
• Light stretching exercises
• Avoidance of heavy lifting (no lifting over 5 kg)

Weeks 4-6

• Increasing walking duration to 30-45 minutes
• Light-pace swimming
• Cycling (preferably stationary)

Week 6 and Beyond

• Regular cardio exercises (at least 150 minutes per week)
• Resistance exercises
• Pilates and yoga
• More active sports (hiking, tennis, dancing)

Regular exercise supports weight loss, reduces skin sagging, and preserves muscle mass.

Possible Side Effects and Complications

Some side effects may occur during the post-operative period:

Common and Usually Temporary Side Effects

• Nausea and vomiting: Often caused by eating too quickly or inadequate chewing
• Hair loss: May occur between 3-6 months due to rapid weight loss and protein deficiency
• Fatigue: Energy levels may decrease during the first months
• Constipation or diarrhea: May occur due to dietary changes
• Feeling cold: Common during rapid weight loss
• Skin sagging: A natural consequence of the weight loss process

Symptoms Requiring Medical Attention

A physician should be consulted immediately if any of the following occur:

• High fever (above 38°C / 100.4°F)
• Severe abdominal pain
• Persistent vomiting
• Blood in vomit or stool
• Severe shortness of breath
• Swelling and pain in the legs
• Excessive redness or discharge at the wound site

Dumping Syndrome

A condition that may occur particularly after gastric bypass. When sugary or high-carbohydrate foods are consumed, symptoms such as:

• Heart palpitations
• Sweating
• Dizziness
• Abdominal pain
• Diarrhea

may appear. It can largely be prevented by avoiding sugary foods.

The Psychological Process

Rapid weight loss leads to significant changes in both the patient's physical and psychological state. Possible situations include:

• Body image changes: Seeing the old self in the mirror or difficulty adapting to changes
• Struggle with eating habits: Emotional fluctuations during adaptation to new portion sizes
• Changes in social life: Reactions from those around and a sense of difference in social settings
• Depressive symptoms or anxiety: May appear in the first months

During this process, support from a psychologist or psychiatrist contributes to healthy management. Bariatric patient support groups are also a valuable resource.

Skin Sagging and Aesthetic Procedures

As a result of rapid weight loss, sagging may occur in areas where the skin loses its elasticity. It is most commonly observed in the abdomen, arms, thighs, and breasts.

To reduce skin sagging:

• Gradual weight loss is important
• Regular resistance exercises preserve muscle mass
• Adequate protein intake supports skin structure
• Adequate water intake contributes to skin elasticity
• Skin moisturizers can be used

After weight loss is complete (generally 12-18 months after surgery), aesthetic surgery options may be considered for significant sagging:

• Abdominoplasty (tummy tuck)
• Brachioplasty (arm lift)
• Mastopexy (breast lift)
• Thigh lift surgery

Pregnancy and Bariatric Surgery

Important considerations for female patients of childbearing age:

• Pregnancy is not recommended during the first 12-18 months after surgery
• During this period, weight loss stabilizes and the body reaches nutritional balance
• An effective contraceptive method should be used during this time
• Pregnancy plans should be evaluated together with the physician
• Vitamin and mineral supplements are specially adjusted during pregnancy

Follow-Up Appointments

Regular follow-up appointments are vital after surgery. The typical follow-up schedule:

• Week 1
• Month 1
• Month 3
• Month 6
• Month 12
• Then annual follow-ups (for life)

At each follow-up, the following are evaluated:

• Weight and BMI tracking
• Blood tests (vitamin and mineral levels)
• Review of eating habits
• Evaluation of possible complaints
• Monitoring of psychological well-being
• Monitoring of accompanying conditions (diabetes, hypertension)

Weight Regain and Prevention

The highest weight loss occurs within the first 12-18 months after surgery. After this period, some patients may experience some weight regain. This is generally related to:

• Deterioration of eating habits
• Skipping regular follow-ups
• Decrease in physical activity
• Gradual enlargement of the stomach

To prevent weight regain:

• Strict adherence to the nutrition program
• Maintenance of regular exercise habits
• Continued attendance at follow-up appointments
• Management of snacking and emotional eating
• Seeking dietitian and psychologist support when needed

Long-Term Lifestyle

Bariatric surgery requires a permanent lifestyle change. For successful long-term management:

• Eating slowly and mindfully
• Eating protein first
• Avoiding sugar and processed foods
• Drinking plenty of water
• Exercising regularly
• Getting sufficient quality sleep
• Managing stress
• Maintaining a social support network
• Not skipping regular health check-ups
• Regular use of vitamin and mineral supplements

When these habits are established, the results of the surgery become sustainable in the long term.
