How Does Gastric Artery Embolisation Help in Weight Loss? 

Obesity has become one of the most significant health concerns worldwide. Many individuals struggle to lose weight despite following diets, exercise routines, and lifestyle changes. While traditional weight-loss surgeries are effective, not everyone is ready for or eligible for surgical procedures.

One promising minimally invasive treatment gaining attention is Gastric Artery Embolisation. This innovative procedure helps control hunger hormones and supports weight loss without major surgery.

‍

Understanding Gastric Artery Embolisation

Gastric Artery Embolisation (GAE) is a non-surgical, image-guided procedure performed by interventional radiologists. It focuses on reducing the production of a hormone called Ghrelin, which is responsible for stimulating appetite.

Ghrelin is primarily produced in the upper part of the stomach known as the Gastric Fundus. The blood supply to this region mainly comes from the Left Gastric Artery.

In the procedure, doctors reduce blood flow to this artery using tiny particles. This decreases ghrelin production, helping patients feel less hungry and more satisfied after meals.

‍

How the Procedure Works

Gastric Artery Embolisation is usually performed in a hospital’s radiology suite and typically takes about 1 to 2 hours.

The procedure involves the following steps:

  1. Local anesthesia is administered to numb the area, usually near the wrist or groin.

  2. A thin catheter is inserted into a blood vessel and guided toward the left gastric artery using imaging technology.

  3. Tiny medical particles are injected to partially block the artery supplying the stomach's ghrelin-producing area.

  4. Reduced blood flow leads to lower ghrelin levels, which helps decrease appetite.

Because it is minimally invasive, patients usually experience shorter recovery times compared to traditional bariatric surgery.

‍

Benefits of Gastric Artery Embolisation

This procedure offers several advantages for individuals struggling with weight management:

1. Minimally Invasive
No large incisions or surgical removal of stomach tissue are required.

2. Reduced Appetite
By lowering ghrelin production, patients naturally feel less hungry.

3. Faster Recovery
Most patients can return to normal activities within a few days.

4. Lower Surgical Risk
Compared to major bariatric procedures, the risk of complications is generally lower.

5. Potential for Sustainable Weight Loss
Studies suggest patients may experience gradual and meaningful weight loss over time.

‍

Who May Benefit from This Procedure?

Gastric Artery Embolisation may be suitable for individuals who:

  • Have moderate obesity

  • Have not achieved results through diet and exercise alone

  • Are not eligible or willing to undergo bariatric surgery

  • Are seeking a minimally invasive weight-loss option

However, the procedure is not a replacement for healthy lifestyle habits. Long-term success still depends on balanced nutrition and regular physical activity.

‍

Possible Side Effects

Like any medical procedure, Gastric Artery Embolisation may have some temporary side effects, including:

  • Mild abdominal pain

  • Nausea

  • Fatigue

  • Temporary stomach irritation

Most of these symptoms are mild and resolve within a few days after the procedure.

‍

The Role of Lifestyle After the Procedure

While the procedure helps control appetite, healthy lifestyle choices remain essential. Patients are usually advised to:

  • Follow a balanced, calorie-controlled diet

  • Stay physically active

  • Maintain regular medical follow-ups

  • Work with nutrition and weight management specialists

These steps help maximize the long-term benefits of the treatment.
