This topic is about a person who recently had an ileostomy reversal surgery and is experiencing some concerning symptoms. After the surgery, the initial recovery seemed to be going well, but a week later, after eating a large meal, the person began to experience severe cramping, nausea, and vomiting. This has raised concerns about whether these symptoms are part of the normal recovery process or if they indicate a more serious issue.

Here are some pieces of advice and insights that might be helpful:

1. It is important to seek immediate medical evaluation, either by going to the emergency room or considering readmission to the hospital. Persistent symptoms like vomiting, cramping, and a feeling of fullness could suggest complications at the site of the new internal connection, such as a leak, stricture, or blockage, which need professional assessment.

2. Until a medical evaluation can be done, it is advisable to stick to a near-liquid or very soft diet. Avoid foods that are high in residue and do not digest completely, as they might exacerbate the symptoms.

3. Be mindful of potential lactose intolerance. Since the chocolate milkshake seemed to trigger vomiting, it might be wise to eliminate dairy products temporarily to see if symptoms improve.

4. Understand that post-surgical swelling can take 4 to 6 weeks to subside. During this time, some foods might continue to cause issues. It is important to introduce solid foods slowly and cautiously to see how the body reacts.
