No. Bariatric surgery is weight loss surgery having profound effect on other comorbids like diabetes, hyptertension, PCOS and sleep apnea. Whereas tummy tuck / liposuction are cosmetic procedures for people with normal or near normal body weight, without any effect on obesity or weight related comorbids.

6-8 kgs in 15 days, then 1-2 kgs each month till a plateau phase is achieved which is variable for different patients. It may vary depending on initial weight, procedure type, body metabolism, comorbids, diet & physical activity. Higher the initial weight & balanced lifestyle, greater the weight loss.
Following table provides a rough estimate of weight loss (Actual may vary due to baseline weight, metabolic rate, patient factors, surgery selected etc.
| Time After Surgery | Expected Excess Weight Loss | Description | 100kg (60kg ideal & 40kg excess weight) |
|---|---|---|---|
| 15 days | 15% | Rapid loss, mostly fluids | 06 Kgs |
| 3 Months | 25% | Energy improves; appetite stabilizes | 10 Kgs |
| 6 Months | 40% | Clothing sizes drop significantly | 16 Kgs |
| 12 Months | 70% | Plateau may start here | 28 Kgs |
| 18–24 Months | Up to 80% | Final stabilization | 32 Kgs |
Yes, in upto 30% patients, weight regain occurs if followed upto 10 years. It depends on initial weight, procedure, body metabolism, eating habits, exercise/physical activity etc. A 70 % success of bariatric surgery beyond five years is by far the highest among all weight loss modalities i.e. diet & exercise (1%), medicine (10%) and endoscopic procedures (20-30%)
1% serious complications. Leak, bleeding, clotting of blood in legs (deep venous thrombosis), chest infection etc. Strict precautions are taken to prevent these complications, yet one out of a hundred patients may experience any of these complications.
These are relatively non serious provided patients follow and get tests done as per plan.
Protein and vitamin deficiency upto 10%
Structural complications like ulcer, narrowing etc. upto 2 %
Therefore, lifelong follow up and compliance to the dietician is paramount.
