Singer-songwriter Lisa Marie Presley passed away due to a twisted small bowel, which the medical examiner linked to bariatric surgery she had years earlier. This type of surgery can sometimes cause scar tissue that leads to bowel obstructions. However, some experts are skeptical about this link, as the location of the scars from such surgeries typically doesn't align with where the obstruction occurred. Bowel obstructions can result from various surgeries, not just bariatric ones, and can be life-threatening if not treated promptly. Symptoms include persistent abdominal pain, vomiting, and abdominal distention. While bariatric surgery has risks like any surgical procedure, it is generally safe and effective for weight loss, with benefits often outweighing the risks. The decision between surgery and anti-obesity medications should be individualized and discussed with a doctor.
