Yes, IBD I have ulcerative colitis. A big headache. I guess unless you intend to tell everyone right up front, I wouldn't tell anyone. Because as you go on, you tell this one, not that one, and you forget who you told, and you don't know who told whom. No one really even mentioned my weight loss until I reached 50lbs.....I remember when I hit 35lbs, I couldn't believe no one noticed. Could you imagine if you lost that much and no one noticed? But it seems 50 was the magic number. Some people asked me point blank if I had surgery.....and I couldn't lie, because I felt that eventually they'd hear the truth, as time went on. So, it would be my recommendation, and my friends, either tell no one, or everyone. My mother thought it was OK to tell everyone, people I hardly knew, annoyed me. But other people feel differently, they tell everyone, but keep in mind, if you tell people, like people you work with or friends, and you go out to a restaurant or at a party with food, people look to see what you're eating. I personally feel like I'm lying when people ask me how I lost so much weight. Before I had the surgery, and if someone said they lost 50-100lbs, I'd give them the third degree, not that I was thinking they had surgery, I just wanted to know how they did it, hoping I could do the same. Did they eat a certain food, do a special exercise, something different that I had done over the years. So now people think I did something they couldn't do, and they feel bad, but if you tell them you had surgery, then they might not feel like their losers, know what I mean? Telling your brother is safe enough, usually men don't talk much, and if you tell him not to say anything, as a man, he likely wont'... Sexist, I know.
Good luck, if you pay attention to the quailty of value of the food you eat, you will succed. Always have good food choices in the house, Soup, yogurt, cheese, veggies, milk, getting enough Protein is an issue. It seems that bad things go down easy and good things are harder, big surprise, right?! LOL So help making good choices easier by having the good things in the house and not having the bad things there.........less temptation......you'll do fine, best of luck.
