Phentermine Use after the Sleeve



Recommended Posts

My personal biggest issue before surgery with phentermine is that I gained my weight back plus some when I stopped taking it. With the sleeve and the amount of food I consume now, this wont be an issue. I chose the sleeve specifically to decrease my hunger hormones which had been out of control since early childhood. Having a decrease in my hunger was such a huge selling point for me. I was incredibly disappointed when my hunger remained the same, all that changed was the amount I ate.

MY QUESTION IS THIS: Anyone who has taken Phentermine after weight loss surgery; What has been your experience?

Short RANT ahead of time! Phentermine is the "Chemical Sleeve" so to speak. It takes away your hunger and in addition, ups the metabolism to give you energy. I understand that some people have bad side effects on phentermine, that is the case with any prescription drug. People don't stop taking psych meds because other people have had issues with them, so I am not sure why so many people are against it. I also understand that over 20 years ago there was a deadly combination phen phen but that isn't the case now. People die getting weight loss surgery, does that mean we should condemn it? If phentermine causes issues for you personally stay away from it but why discourage other people from using it as a tool if it works for them? If we honestly look at the situation it is way more drastic to go out and have surgery to lose weight than take a prescribed weight loss pill!! The downside of phentermine is obviously the weight is hard to keep off unless you make life style changes (just like with the sleeve!).

I have taken phentermine before so I am certainly not going to judge one on taking it - no worries there. , too, lost a lot of weight on it then gained it right back. I also have wondered about taking it post-op since I have a bunch left.

I see you have lost a lot of weight with your sleeve. Are you wanting to take the phentermine for more weight loss or just to clamp down on hunger? The only thing I would worry about is becoming mal-nourished with adding the phentermine. (That and the usual side effects like blood pressure.)

I am surprised your hunger remained the same. I thought the sleeve is supposed to remove the gherlin production so no way could it remain the same. Don't get upset with my next question - just throwing it out there for consideration in case you haven't thought about it. Have you considered it might be emotional hunger? That you are not really physically hungry but emotionally?

Pre op, I had great success using phentermine. My only side effect was acne. The only reason I stopped taking it was because it was hard for me to find a Dr to prescribe them. Once I came off of them permanently is when my weight shot up through the roof. With that being said, while my appetite has increased since surgery I am making better choice of what I am eating and am only needing a few bites before I am full. I don't really need a complete appetite suppressant at this point because I am struggling to get food in but I would see no worries in the future for in the future going back on phentermine.

I just hope that I will never have a need for phentermine, or diets or any of that old crap I used to put myself through again. The only option I am debating once at goal is weight watchers for accountability and keeping up the lifestyle chance and learning how to eat anything in moderation.

I am still 60 pounds from goal and unfortunately haven't lost much after the year mark. I became a grazer so I take the phentermine to keep that in check. When I don't feel like Im starving I am making much better food choices! Ive lost 9 pounds in four days after beginning the phentermine.

Not upset at all! I appreciate your response :) I definitely struggle with stress eating if my stress level gets to high. I've made an appointment with a therapist (and a hypnotherapist) to get this in check. I wondered a lot if the hunger was not "real" but I get weird side effects like edgy-ness, slightly shaky, fatigue weakness if I'm not eating every few hours.

I also thought that the sleeve cut at the hunger hormone but it just isn't true for everyone. Hunger must not just be effected by Ghrelin.

Well, if it is working for you ...then why not? Maybe you should double check with your doctor though - and take some Vitamins or something? I guess the only advice I would add is to try to do some other things to jump start your weight loss in addition to phentermine. Perhaps increase your exercise or something. Definitely do what you are doing to deal with stress eating. That way, once you go off phentermine, you maybe can avoid regaining weight like before when you went off it. So, maybe try to make a lifestyle change while taking it and then ween yourself off slowly once you lose the weight.

The sleeve and the phentermine are just tools that buy a person time to deal with lifestyle and emotional stuff, I guess.

There are a lot of factors involved in hunger besides Ghrelin for sure. Other hormones and things (I know Leptin is one) in addition to the emotional triggers and such. It's super complicated.

I can believe Phen/Fen was that long ago!!! I feel so old! Yes there were some rare cases of a condition (primary pulmonary hypertension) with some people who took it that they never fully proved was due to the combination, but they took the Fenfleuramine off the market. So not sure I'd call it deadly. I used the combo and it was the only thing before this surgery that made me feel like my appetite and relationship with food was normal! I was very sad when they took it off the market. I would have rather taken the small risk of PPH than the huge risks associated with obesity!

Anyhow....I think if Phentermine works for you for the short term as another tool in your box, more power to you as long as your doctor is on board. It never worked for me by itself.

There are several hormones responsible for triggering hunger. Some people are no long hungry after surgery, some for just a while and some forever. Most people fall into the first category.

My hunger came back around 5 months, and my surgeon was hardly surprised.

I lost 150 pounds after the sleeve surgery. Then I encountered some health complications (not sleeve related) in 2016. I wasn't able to exercise, had no energy, and wasn't really watching what I was eating. Because of that I "rebounded" about 30 pounds. I went back to the weight management clinic because I wanted to stop it before I regained any more. The doctor gave me a prescription of phentermine, and it "jump started" my weight loss. I was able to stop the regain and shed about 10 pounds that I had regained. I will say though, that I think the benefit for me was mostly mental. After a couple months I realized I really didn't feel any differently on the phentermine than off of it. I went off of it at that pont and lost the rest of my regain by going back to the bariatric diet strictly. Hope that helps!

I kept my hunger at bay with Protein. As soon as I slacked on that, I felt hungry and to be honest, when I lost 119, the hungry feeling was welcome, I knew I was not eating too much. It's natural and normal to feel some hungry.

I feel like a lot of people are not eating right, or have head hunger, or don't realize being hungry is a bit of a good sign.

I suggest OA for anyone who has head hunger.

      Four days post surgery. I am sipping as fast as I can and getting NO WHERE near the goal of 60 - 80 grams of protein or the 64 oz of liquids. I just feel FULL. I don't know if it can still be the gas build up (I would think by now that would be gone) but it is a struggle to drink. And so far I have not had the nausea or spasms and don't want to wander into that territory by pushing too hard with liquids. I about passed out today as it was my most "strenuous" day. Went from second story to basement for shower and I was sure I was going to pass out. Looking back on my last few days I have had a total of less than 1000 calories. Am I just not getting enough nourishment in me? Once again a friday where I can't get ahold of the doc until Monday rolls back around so I am hoping maybe someone here has some experience on how to keep energy going. I do have fibromyalgia too and that may be where some added fatigue comes into play. How did you all fair with the goals the week after surgery?

      2 days until I fly out to San Diego to have my Bypass Surg. in Tiajuana Mexico. Not gonna lie, the nerves are starting to surface. I don't fear the surgery itself, or the fact that I'm traveling alone, but its the aftermath that I'm stressing about the most, after this 8 week wait. I'm excited to finally be here, but I am really dreading the post surgical chapter. I know its going to be tough, real tough and I think I'm just in my head to much now that the day i here. Wish me luck, Hopefully I'm one of the lucky ones, and everything goes smoothly. Cant wait to give an exciting update,. If there is anyone else have a June bypass or even a recent one, Id love to have someone to compare war stories with. Also, anyone near San Antonio Tx? See ya soon with the future me. 💜

      2. Selina333

        I'm in Houston so kind of near you and had the sleeve in Dec. Down 61 lbs. Feeling better. Was definitely worth it. I hope the everything is going well for you. Update us when you can!

      3. Doughgurl

        I am back home after my bypass surgery in Tiajuana. I'm post op day 4. Everything went great! I guess I'm one of the lucky ones who have not encountered much pain at all, no nausea thus far and I'm having no problem keeping down broths and water. Thank you for your well wishes. I cant wait to keep up this journey and have a chance at better health and simply better quality of life. I know there will be bumps in the road ahead, and everything won't be peaches and cream, but at least I have a great start so far. 😍

      I am new here today... and only two weeks out from my sleeve surgery on the 23rd. I am amazed I have kept my calories down to 467 today so far... that leaves me almost 750 left for dinner and maybe a snack. This is going to be tough for two weeks... but I have to believe I can do it!

      Hey everyone. I'm new here so I thought I should introduce myself. I am 53y/o and am scheduled for Gastric Bypass on June 25th, 2025. I'm located in San Antonio, Texas. I will be having my surgery in Tiajuana Mexico. I've wanted this for years, but I always had insurance where bariatric procedures were excluded. Finally I am able to afford to pay out of pocket.  I can't wait to get started, and I hope I'm prepared for the initial period of "hell". I know what I have signed up for, but I'm sure the good to come will out way the temporary period of discomfort and feelings of regret. I'd love to find people to talk to who have been through the same procedure or experience before. So I look forward to meeting you all. Hope you have a great week!

        I'm so happy for you! You are about to change your life. I was so glad to get the sleeve done in Dec. I didn't have feelings of regret overall. And I'm down almost 60 lbs. I do feel a little sad at restaurants. I can barely eat half a kid's meal. I get adults meals often because kid ones don't have the same offerings at times. Then I feel obligated to eat on that until it's gone and that can be days. So the restaurant thing isn't great for me. All the rest is fine by me! I love feeling full with very little. I do wish I could drink when eating. And will sip at the end. Just a strong habit to stop. But I'm working on it! You will do fine! Just keep focused on your desire to be different. Not better or worse. But different. I am happy both ways but my low back doesn't like me that heavy. So I listened (also my feet!). LOL! Update us on your journey! I'm not far from you. I'm in Houston. Good luck and I hope it all goes smoothly! Would love to see pics of the town you go to for this. I've never been there. Neat you will be traveling for this! Enjoy the journey. Take it one day at a time. Sometimes a few hours at a time. Follow all recommendations as best you can. 💗

      2. Doughgurl

        Thank you so much for your well wishes. I am hoping that everything goes easy for me as well. We don't eat out much as it is, so it wont be too bad in that department. Thankfully. Also, I hear you regarding your back and feet!! I'd like to add knees to the list. Killing me as we speak! I'm only 5' so the weight has to go. Too short to carry all this weight. Menopause really did a doosey on me. (😶lol) My daughter also lives in Houston. with her Husband and my 5 grand-littles. I grew up in Beaumont, so I know Houston well, I will be sure to keep in touch and update you on my journey. I may need some advice in the future, or just motivation. Thank You so much for reaching out, I was hoping to connect with someone in the community. I really appreciate it. 💜
