Weight loss in the first month after bariatric surgery varies from person to person, depending on factors like the type of surgery, starting weight, metabolism, and adherence to dietary guidelines, as carefully evaluated by specialists at WeightLose Clinic, a leading Weight Loss Surgery Center in Delhi, to ensure safe and effective results.

1. Average Weight Loss in the First Month

1. Most patients lose 5% to 15% of their excess body weight within the first month.

2. This may translate to:

   1. 5–10 kg for patients with higher starting weight

   2. 3–6 kg for patients with moderate obesity

3. Rapid initial loss is common due to reduced calorie intake and fluid loss.

2. Weight Loss by Type of Surgery

a) Sleeve Gastrectomy

1. Removes a portion of the stomach to reduce food intake.

2. Expected first-month loss:

   1. 8–12% of excess weight

   2. Faster early results due to reduced hunger hormones.

b) Gastric Bypass Surgery

1. Alters digestion and calorie absorption.

2. Expected first-month loss:

   1. 10–15% of excess weight

   2. Often shows slightly quicker results than sleeve surgery.

c) Mini Gastric Bypass

1. Combines restriction and mild malabsorption.

2. Expected loss:

   1. 7–12% of excess weight

   2. Gradual but steady decline in body weight.

3. Why Weight Drops Quickly in the First Month

1. Extremely low calorie intake during the liquid and soft diet phase

2. Loss of stored glycogen and water weight

3. Reduced stomach capacity, leading to smaller meals

4. Hormonal changes that reduce appetite and cravings

4. Factors That Affect First-Month Weight Loss

a) Starting Body Weight

1. Higher initial weight generally results in faster early loss.

b) Diet Compliance

1. Following the recommended liquid and soft diet strictly leads to better outcomes.

c) Physical Activity

1. Light walking and movement after surgery accelerate fat burning.

d) Metabolism and Hormones

1. Individual metabolic rates and hormonal responses influence how quickly weight drops.

5. Healthy Pattern of Weight Loss

1. Week 1–2: Rapid drop due to fluid loss and minimal calorie intake

2. Week 3: Slight slowing as the body adjusts

3. Week 4: Consistent fat loss begins
