NEW DELHI: A Bangalore-based doctor has advocated for more attention on Median Arcuate Ligament Syndrome (MALS) as he has stressed that this disease affects only 1 in 20,000 people. Dr. JS Rajkumar, Founder of Lifeline Group of Hospitals, while speaking to The New Indian, said, “It is a very rare disease, affecting only one in 20,000 young people.

A 2020 report in the Journal of Vascular Surgery also sheds light on the complexities surrounding MALS.

It says that this condition arises from the compression of the celiac artery by the median arcuate ligament, leading to a range of symptoms associated with foregut ischemia, including abdominal pain, nausea, vomiting, and weight loss.

Surgical decompression of the MAL, performed through robotic, laparoscopic, endoscopic, or open techniques, is the primary treatment, offering symptom relief in many cases.
