I’m sorry you’re going through this. Given your history of gastric bypass and revision surgery, the symptoms you’re experiencing — severe pain when eating, the feeling of food getting stuck, and rapid weight loss — are concerning and should be evaluated right away.
These symptoms could be caused by a stricture (narrowing of the stomach opening), an internal hernia, a bowel obstruction, or an ulcer. All of these conditions can make it difficult for food to pass through and cause severe pain. Significant weight loss and difficulty eating also raise concerns about malnutrition, which can impact your overall health.
Please contact your surgeon or gastroenterologist as soon as possible. If the pain is severe, you’re unable to eat or drink, or you’re feeling dehydrated, it’s important to seek emergency care right away. In the meantime, try to stay hydrated by sipping water or clear fluids. If you can tolerate it, try very small amounts of soft or pureed food, but stop if it causes pain. This is a serious situation, and I encourage you to seek care as soon as possible to avoid complications.

Given your medical history of gastric bypass and recent rapid weight loss, the symptoms you're describing could indicate a anastomotic stricture, marginal ulceration, gastro-gastric fistula, or other complications related to your prior surgery. You may need imaging or an endoscopy to determine the cause and prevent further complications.
