This topic is about someone who had an ileostomy many years ago due to ulcerative colitis and is now experiencing recurring episodes that feel like a severe "stomach flu." These episodes involve intense abdominal pain, vomiting, and a very watery, high-volume output from the stoma. The person is looking for insights into what might be causing these episodes and how to prevent them in the future.

Here are some possible causes and advice:

1. Mechanical causes:
- Over time, scar tissue from the surgery (adhesions) might be causing the bowel to kink or narrow.
- A twist in the bowel (volvulus) or a partial obstruction could be causing the symptoms, especially if there has been weight gain adding pressure.
- It is recommended to consult a physician for imaging and assessment, as persistent pain should be evaluated promptly.

2. Infectious or systemic causes:
- Another person had a similar experience that was diagnosed as "stomach flu," requiring hospital treatment with IV fluids and electrolytes. They noted that low sodium and potassium levels made recovery longer.
- Preventive measures that helped them include getting an annual flu vaccination and taking daily vitamins to support immunity and overall health.

3. Supportive management during attacks:
- It's important to monitor stoma output, hydration levels, and electrolytes. Seek medical care early if the output is excessive or vomiting continues.
- Hospital treatment with IV fluids might be necessary to quickly address dehydration and restore electrolyte balance.
