I have experienced several severe intestinal blockages as a result of a lot of post-surgical adhesions, after two colorectal cancer surgeries, in 2015 and for construction of a j-pouch in 2016, (both major abdominal resections, big zippers). Anything to avoid this horror! .... I now take super full-spectrum digestive enzymes every day, three capsules at each meal. And drink lots of water. (I have read that so-called 'pyrolytic' enzymes might help to reduce adhesions over time. Trying them, too.) Triggers include extreme stress. Food triggers: accidentally eating even a tiny amount of palm oil puts me in hospital every time!!!! ... very bad (in almost all prepared foods, so I read the labels EVERY time that I buy anything, and no restaurant meals any more, either). Also eating too much fresh vegetables or fruit at one time, including peppers, apples or broccoli. (Well-cooked, and small amounts is okay, well-chewed. No heavy fibre, either.) Small meals, no matter how hungry. .... Each episode, searingly painful abdominal cramps beginning in two locations (CT scan showed large adhesions wrapped around small intestines), rapidly getting worse, and unrelenting, violent vomiting. At the hospital, given large amounts of natural morphine sulphate for pain, and large amounts of Gravol-type anti-emetic to relieve vomiting. Each time, hospitalized for 3-5 days to rest bowel, nasal-gastro tube to continuously remove stomach secretions (otherwise, unbelievable vomiting, torn stomach lining). I have managed to stave off four more severe episodes (thank god) by walking around for hours, deep and very slow (mindful) breathing, while slowly sucking on 90 mg of children's chewable Gravol, as SOON as symptoms start, and taking 15 mg of morphine sulphate for pain. (Prescription, I keep a small amount handy.) Definitely a horrible thing to experience. (I am very lucky to receive compassionate care when I show up at emergency with my 'puke bucket'. Too sick to drive, barely able to get dressed. Grateful for a ride.) Sure hope some of this helps.
