Obesity is a medical condition that occurs when an individual has an excess amount of body fat. Obese individuals have a body mass index (BMI) of greater than 30. 


Being very overweight can bring about many negative effects, including an increased risk of developing chronic diseases. Some conditions influenced by obesity include:

  • Cardiovascular disease
  • Stroke
  • Hypertension
  • Type 2 diabetes
  • Gallstones
  • Gout
  • Infertility
  • Sleep apnoea


Some factors that may contribute to an individual becoming obese include:

  • Lack of exercise/activity
  • An unhealthy diet including high levels of fat, sugar and salt 
  • excessive food consumption in general
  • Lack of sleep
  • Genetic predisposition
  • Ageing (metabolic rate slows down)
  • Certain existing medical conditions (e.g. hypothyroidism, polycystic ovary syndrome, etc.)


Bariatric artery embolisation is the latest technique to help patients with a high body mass index to achieve weight loss. 

This procedure may be suitable for patients who are facing serious health conditions as a result of their high body mass index and have found that:

  • Weight loss unsuccessful with lifestyle modification, diet change and medication 
  • Are unsuitable candidates for metabolic weight loss surgery.  

This is a minimally invasive day procedure done under light sedation or local anaesthesia depending on the patient’s preference. A catheter is inserted from the radial artery in the wrist and navigated under image guidance into the arteries supplying the part of the stomach with the hormones that make a person hungry. These arteries are then blocked. The expected weight loss from this procedure is about 10-15% of current body weight.
