A gastric sleeve procedure is performed for which purpose in the patient population?

The gastric sleeve procedure, also known as sleeve gastrectomy, is primarily performed as a weight loss intervention. This surgical technique involves the removal of a significant portion of the stomach, resulting in a tube-like structure or "sleeve" that restricts food intake. By reducing the stomach size, patients experience a decrease in hunger while also leading to hormonal changes that enhance weight reduction.

This procedure has gained popularity as an effective solution for obesity and is typically recommended for individuals who have not achieved sustainable weight loss through diet and exercise alone. It is particularly beneficial for those with a body mass index (BMI) over a certain threshold or those who suffer from obesity-related health issues.

The other options mentioned do not align with the primary purpose of gastric sleeve surgery. Gastric bypass surgery is a different type of bariatric procedure aimed at weight loss as well but involves rerouting the digestive tract. Treatment of gastric cancer and management of peptic ulcers involve different surgical approaches and are not indications for a gastric sleeve. The focus on significant weight loss makes option B the correct answer.
