Orlistat for Weight Loss (Obesity/Overweight) "I used Alli because I wanted to lose weight but needed help with commitment to my diet. It's been about a week and I lost 5 lbs. Surprisingly, it helped with my bloating and constipation, which may also be why I lost 5 lbs in a week. Not looking for a miracle pill, just something to help out, like a guard rail at the bowling alley. You may not get a strike, but at least you didn't get a gutter ball! lol"

Orlistat for Weight Loss (Obesity/Overweight) "If you're having problems with oily farts, then you're not following the recommendation of a reduced-fat diet! That oil is fat your body isn't absorbing. Anytime it starts happening to me, it's my reminder I need to watch what I eat! I also have IBS. I now have regular BMs and haven't been as bloated. Also, my appetite isn't as strong, I'm not binge eating, and I'm not craving junk food as much."

Orlistat for Weight Loss (Obesity/Overweight) "The moment I hit 30, my metabolism slowed. Despite working out and eating healthy, I felt bloated after I ate, and I was irregular. I really felt like my body was overloaded and not processing things at a normal speed, but I felt lethargic and hungry, so I was starting to get depressed over the whole thing. I tried diuretics/lax and increasing fiber to no avail, and the cramping sucked. This is making a real difference. I feel leaner and lighter, and my joints aren't so overtaxed carrying the extra weight. My energy is way better. It's messy at times and not easy, but if you have two weeks of downtime where you can be by the bathroom, give this a go."

For Weight Loss (Obesity/Overweight) "I have been taking Orlistat on prescription for about 5 months now, and in total, I have lost 3 stone. I have cut out full-fat milk and still have the odd chocolate bar and takeaway. It is brilliant. Now and again, you can feel a bit bloated, then once you have been to the toilet, you feel a whole lot lighter, absolutely brilliant drug."

For Weight Loss (Obesity/Overweight) "I tried Orlistat years ago but was ignorant toward its use (not controlling fatty foods and having lovely sunset yellow accidents), so I gave it up. I have struggled with PCOS (Polycystic Ovary Syndrome) since the age of 17, and one of my symptoms has been weight. I've always been overweight, and when I diet and exercise, the hormonal imbalance makes it harder to lose the lbs, and I gain muscle instead. After two kids, it's become harder to lose any weight, so I decided to go back to prescribed Orlistat. Now 4 days in, bloated, flatulence, no accidents, looser stools, and bloating goes away after relieving myself. I haven't weighed myself yet. (On the 2nd day, I felt dizziness, but no more). I'm careful with fat consumption and try not to snack in between meals."

Orlistat for Weight Loss (Obesity/Overweight) "Do not waste your money. I repeat, do not waste your money. I have been taking Alli for over a week now, and it has made me bloated, and I even gained a pound. Last night was the last straw. As I was washing my hands, I had an orange oily accident, and this was so embarrassing it leaked through the shorts, and I almost cried. Now I'm stuck with a bottle of capsules and out $70, a complete waste."
