I stocked up on gas-x strips, B12, protein shakes (seriously, every flavor because they get old fast). I had a heating pad to help with gas pains....umm it was pretty basic the first couple weeks. Chicken broth (I recommend bone broth as it tastes better and has protein).

I had hair loss. It was sad for me because my hair is thin to start with and then got so thin you could see my scalp. Then I used cover ups and prayed I didn't sweat or got caught in the rain other wise I would have black streaks dripping down my forehead. It grew back almost a year later but very curly. I also took vitamins daily and still do. I had trouble with gas also. Funny story, 3 weeks after surgery I bent over to pick up a pencil from the floor, when I bent over I let out a big burp. It was so loud, I sounded like an angry bear but the relief was so satisfiying. Good luck with your surgery and let us know how you are doing.

Hair loss is inevitable but biotin and niacin help it come back, not fall out.

MrsJKSmith19, don't pre-worry about anything. As long as you follow the guidelines you probably won't have any issues. If something does come up just get a hand on it early. Listen to your body and you'll be fine.

Hair loss occurs in 40% of WLS patients.
