For Weight Loss (Obesity/Overweight) "I've been taking orlistat 120 mg for 11 days. I've lost 1 st and 4 lbs so far! I am off the scale obese, so I needed to lose a chunk of weight in order for me to have the willpower to carry on. I have no more than 3 g of fat in each meal, I take a multivitamin at night as directed. I feel great on it... just hope I manage to continue. I have had no major issues, no oily stools. Eating lots of fruit and veg and drinking loads of water. I still have my no sugar fizzy pop and my cups of tea and coffee."

For Weight Loss (Obesity/Overweight) "Started Orlistat as well as Metformin two days ago. I have no health problems, I just have struggled with weight forever. So far, I've lost 4 lbs in the 2 days of taking both medications. Really hoping this continues. I am on a low cal/low fat diet, and yes, I do have very soft stools and I do have bright orange oil when I pass stool, but no accidents so far. It's really not bad at all, and for me, it's a sign that it's working! The pros far outweigh the cons if you have been overweight your whole life. My highest weight was 290 last year, and so far I'm at 257. My goal weight is 170."

Orlistat for Weight Loss (Obesity/Overweight) "I've been taking Xenical for over a week now. I am on a low-fat, healthy diet, and I want to speed the process of losing a few more kilos before my summer holidays. Despite being on a healthy diet, I have to say that I've had oily stools and accidents. So far, no major weight loss."

For Weight Loss (Obesity/Overweight) "I've been on orlistat now for 4 weeks. Had my first weigh-in today, as I didn't want to get weighed until I went back to GP. I have lost 22 lb, it's fantastic, so pleased. I have a bit more to go. I have experienced some side effects: loose stools, lol, but if you put the hard work in, it pays off. Onwards and upwards."

For Weight Loss (Obesity/Overweight) "I'm currently on day two. I am eating extremely well: fruits, veggies, and lean meats. Having lots of loose stools and gas on day two. Is this normal? I only take the pill with lunch and dinner since naturally I don't get hungry enough to eat until lunch. Going to keep going and crossing my fingers that with light exercise and portion control I can lose a few pounds. I am currently 5'3" and 148 pounds."

For Weight Loss (Obesity/Overweight) "I have been taking this for three days now, eating lots of veggies, fruits, and lean meats. On day two, I experienced an upset stomach and lots of diarrhea. However, I feel fine on day three. Not sure why day two was so rough?! I'm 5'3" and 148 lbs. Hoping to get to 130 lbs."

For Weight Loss (Obesity/Overweight) "I have started using Orlistat three weeks ago. With diet and a bit of walking, I lost one kg only. Only 1 kg in three weeks! With all the horrible side effects, 1 kg is nothing. It caused me stomach pain, oily stool, gas, and diarrhea every day. It’s not worth it!"

For Weight Loss (Obesity/Overweight) "I started orlistat one week ago, prescribed by my GP for weight loss aid. Last Monday, I weighed 15 stone on the button. Today, I weigh 14 st and 8 lbs. So, approx 6 lbs weight loss in just a week. In honesty, I haven't changed my diet that much. I always eat relatively well at work. My breakfast contains little or no fat, my lunch is mainly healthy, but I still eat crap in the evenings through boredom. I haven't done any exercise yet, but I MUST start. I experience the oily stools at least 3-4 times per day. I take 3 tablets per day around 15 minutes after each meal. I did read some reviews that said, 'the worse you eat, the more you lose.' I don't know if this is true, I just know that it is different for everyone."

For Weight Loss (Obesity/Overweight) "I started taking this five days ago, no oily stools and keeping to a very low-cal diet, walking, and I don't feel hungry, which is great. I do have some very, very bad side effects, though, constant diarrhea so bad I’m not eating anything and only drinking water. This has been for 2 days now, and I have also gained two new friends - piles! Big ones I have never had these in my life. I have stopped taking the tablets because I’m simply not eating, maybe they don’t agree with me. I wanted to make other people aware of other side effects which haven’t been listed."

For Weight Loss (Obesity/Overweight) "I’ve been taking orlistat for about 6 weeks and have lost 10 lbs in combination with a low-calorie diet; however, I do allow for some splurges on the weekend. The weight loss effect seems to increase over time, as this week I lost 3 lbs without changing my diet. I have only experienced mild side effects (oily stools) and then only if I eat a meal higher in fat than usual. Normally, I eat low fat and don’t have any side effects at all."

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) "We all know the side effect about diarrhea of those pills, but it's totally not candy. As a type 1 diabetic, I do a blood test every 6 months to watch the function of my kidneys. My blood test is very bad after Alli. The kidneys are really tired because of Alli. ALWAYS ask your doctor before using it. Alli is not candy, not natural. The first week I lost 3 pounds, and that's it. So no... it's totally not worth it."

For Weight Loss (Obesity/Overweight) "Bought a month’s worth back in July 2020. I was losing a bit of weight over the first 3 weeks-about 7 pounds, to be exact. I bought this after a recommendation for Polycystic Ovarian Syndrome. I was admitted into the hospital in August for pancreatitis, and I have had problems with this for 6-7 months. I stopped taking the medication and began again in November 2020, but gave it up within a week due to the fact I just couldn’t commit to it, and I was very ill (diarrhea, stomach pain, more pancreatitis pain), which was unusual because I had been fine for a while. I purchased some more just 2 weeks ago, but I am packing it in for good after reading 2 cases of orlistat causing acute pancreatitis."

For Weight Loss (Obesity/Overweight) "So I was a little skeptical. Initially, I wanted a prescription of Ozempic, but orlistat was the best thing I could get and a fraction of the price. I got the drug and read what it did. I was a little disappointed, to say the least. However, I gave it a shot. I’ve been constipated for most of my life and taken laxatives as an adult - it got worse after the birth of my first child. I felt like my constipation got worse in the first week or two of taking the drug and even reported to a girlfriend that it was no good, it made me worse. However, I stuck with it - and after two weeks, I actually started to feel better. I had improved energy, I go to the toilet frequently, although a bit runny, and have to clean the bowl all the time as fecal matter is quite orange and stains the porcelain. And after about seven weeks, I can say I’ve lost a couple of kilos at least. So I love orlistat, the hardest part is remembering to take it before meals three times a day. But it is forgiving if you do miss a dose."

Orlistat for Weight Loss (Obesity/Overweight) "I used Alli for about three weeks. I didn't notice it helping me lose weight faster than I can with a Weight Watchers program. It did increase my bowel movements. I did have some stomach discomfort and gas. I stopped using it at the end of the third week because I went out to dinner and took my pill with my meal, and it made me extremely ill. Vomiting and diarrhea for over eight hours!!! I would not recommend this product to anybody!!! Weight Watchers is working out very well for me. Eating healthy and exercise is the only way to go, there is no magic pill!!! I had to find out the hard way!"

For Weight Loss (Obesity/Overweight) "The first month, I felt like I was losing weight, and the fat was really coming out of me in orange, oily stools. Then I bought the second bottle on Amazon.com, and the fatty stools were gone, replaced with plain diarrhea. I discontinued it because I wasn't losing weight anymore. A year later, I still am experiencing the same side effects and am fatter than ever. I am hoping with enough time, the gastrointestinal side effects will get better and I can have a solid stool. Any weight I initially lost was minimal (less than five pounds) and I gained it back, and I had to spend too much time on the toilet."
