Andrina,
What do you eat in a day? Can you describe your breakfast, lunch, and dinner.
I think I read one of your previous where you mentioned you have resumed working. If you don't overcome and move past your fear of eating and possible blockage, you will become so weak you cannot think properly, make decisions, walk, or function at work. Your body will shut down and you will damage your precious organs without proper food. Water is great but you already know that it's not nutritious and it's not food. Your boss and colleagues will notice your weakness and while they may be sympathetic at first, it can wear thin if you don't take care of yourself and if they have to make up for any slack. You say you have trouble sitting: Your tissues are trying hard to heal and protein is essential for the healing process, but you are starving yourself of the process.
If you don't eat nutritious food you are depriving your body at a time when it survived an intense surgery, had an organ cut right out, and tissue and muscles were sliced in half. In order for your tissues and muscles to heal and knit together, you must eat protein rich food. No fiber, raw, or acidic foods for now, so next time ask your husband to skip the onions and tomatoes, and say yes to the protein rich, omega rich salmon, and the filling potatoes. You will have frequency and gas and all the rest. There is no escaping it; we have all had the symptoms. Your body is trying to learn how to live in a new way and you need to help it, not starve it. If you didn't have the surgery, you might be going fewer times, but you risk cancer.
If you want to get well and be strong and vital, not weak or exhausted or live in fear of blockages and cramps, or be a slave to that fear, sort out your daily food choices. Eat whole foods and eat regularly: 3 meals a day, and snacks if you need them. Your plate should have 3 simple things in your first year after surgery: simply prepared protein, a carbohydrate, and a well cooked soluble vegetable (peeled zucchini or cooked spinach, or sweet potato). No acidic or rich sauces, skins, or processed foods. Eat clean. You're a smart cookie. You've helped others on this site with encouragement and love and support. Do the same for yourself. Treat yourself like a child that you love. You would make sure a child eats good food regularly, wouldn't you? Help your mind and body heal, and eat properly. This is tough love.
