I just wrote a long response to your post complete with quotes and answers, and I lost it all!
First, welcome to the Healing Well Wrapped Club! Glad you've joined us!
Bill's explanation of the hairball episode is exactly right. If you have some water (no ice) or tea handy when you eat it will calm down the esophagus and help to get food through the wrap. Pills can also get stuck and cause irritation, so be sure to drink lots of water after taking anything.
I'm sure your surgeon puts you on liquids to help avoid that problem. Unfortunately surgeons don't provide a lot of information. You need to know that your wrap becomes increasingly more swollen in the first two weeks, peaking on or about 14 days. As that is happening, your swallowing will get more difficult, spasms are more likely, you may get things stuck, and you may experience pain that feels like heartburn (your esophagus is a "dumb organ" and it interprets all pain the same. Also, after a day of swallowing even just water, your wrap can get sore and tired.
This will improve over time. The swelling will gradually subside, and your swallowing will get better.
Stay away from ice water. It will increase spasms.
I was on normal food from Day 5 or 6. My surgeon just warned me to eat only things that could be chewed to a full liquid. (no steak or bread) I just experimented, and deposited non-chewable foods into a handy napkin. I took tiny bites and chewed, chewed, chewed. I had only one problem two months or so in, when I swallowed a partially chewed cherry tomato. I was in a restaurant and only had ice water. I had spasms and discomfort, but it went through with some work, and all was well. I learned my lesson, though and always ordered hot tea with my meals so it would be handy if I needed it.
Your eating will gradually improve over time. You will also be able to eat more normal amounts. It is a very gradual thing, and it's hard to say exactly when you'll be eating normally. I went on vacation at 4 months and that is a benchmark for me. We went out to eat daily, and I was eating everything. Still, I ate smaller bites and chewed thoroughly.
The majority of your healing (your insides have been through a lot...a revision of your upper GI/hernia repair) will take place in the first six months and the rest will take a year. I continued to have more finely tuned healing into the second year. Your outsides heal so quickly that it is deceiving.
Try to surrender to your recovery and follow it where it takes you. If you struggle against it, you will have a more difficult recovery. Just go with the flow!
Again, glad you've joined us!
