I am now a little over one month out. I am still nauseous and have discomfort and I vomit regularly (a few times a week). I have however lost a lot of weight already almost 20 pounds, I would have ever lost this weight without the balloon. Things they don't tell you is that you will look bloated, to the point that it looks like I'm pregnant. My experience immediately after the insertion of the balloon were extremely bad. I was told this was an easy procedure that you don't need anyone with you. This is false you NEED someone with you. After the procedure you will feel like you are dying, you will not be able to hold anything even water down and will immediately throw it back out. I went back to the hospital and checked myself in for a day and paid to have myself hooked up with IVs. This was pricey I paid almost $800 Canadian for one night at the hospital, but it was necessary as I was extremely dehydrated. I was told that this was normal (it is normal) however the doctor and translator made me feel like I was overreacting by wanting to stay at the hospital. During my stay at the hospital I found out other patients with the balloon also checked themselves in. I wish they were a bit more honest, and advised patients that some people do not handle the first few days well and that some stay at the hospital over night. This being said the hospital staff were very kind and attentive. If you are going to get this Balloon done then either take someone with you so that they can take care of your for the few days after the procedure or prepare to pay for a hospital stay.
Lastly DO NOT book your flight the next day like they advised. You will not feel well enough to fly. It took me 4 days after the procedure to feel ok enough to fly. Especially if you are coming from somewhere far like Canada or America.
I would recommend this clinic/hospital over other simply because it is a hospital so if you do need to stay the night I feel like it is safer here.
