For Type 2 Diabetes "I started taking Mounjaro on 9/1. This resulted in the very worst month of my life. WEEK ONE - Super Nauseous, indigestion, stomach pain for 3-4 days of the first week. My appetite went from a 10 to a 2 (which was good). WEEK TWO - I had diarrhea for 3-4 days, along with sulfur belches, nausea, stomach pain. I ended up having to take sick days and go get an IV bag to recover from the dehydration. WEEK THREE - World-class nausea and vomiting. 3 days of vomiting so hard that I ruptured my esophagus. The entire month, if I was not having diarrhea, I was VERY constipated. I lost 9 lbs in one month, but I don't know if it was because I could barely eat due to the sickness. PASS!!"

For Weight Loss (Obesity/Overweight) "I have been on Mounjaro for just two weeks. I've lost 5 pounds without trying. While that's nice, I am posting a very early review to let other newbies know that other than some indigestion the first two days, I haven't had any side effects. I had major constipation on Ozempic. I find taking a daily stool softener, staying hydrated, taking a Metamucil tablet daily, and taking a daily prebiotic (get the refrigerated one in your pharmacy as it has live cultures. Keep it refrigerated!). I'm on 5 mg, but I am moving up to 7.5 next week. I will go to 10 mg if there is no supply of 7.5. My pharmacist said to get my order for the 7.5 mg in at least 7 days early so they can get it in on time. They don't stock it, but they get it overnight. Just FYI, after using Ozempic and Mounjaro, I weigh less than I did 10 years ago. I've gone down 4 sizes and 4 inches off my waist since Christmas! Now a petite XL rapidly headed to petite L."

For Weight Loss (Obesity/Overweight) "I am starting my 3rd month on Mounjaro. I have been overweight/obese most of my adult life. I have lost some weight but not as much as I expected. I feel terrible - I suffer with exhaustion, constipation, indigestion, depression, and nausea. I just do not feel good. It has sucked the joy out of my life. I used to exercise much more when I was not taking Mounjaro. I don't want to do anything. I am wondering if it is worth it?"

For Type 2 Diabetes "I am overweight and was sent to an endocrinologist by my PCP. A1C came back 6.9, and I received the dreaded diabetes diagnosis. The endocrinologist asked me about my eating habits and suggested Mounjaro once a week injection. Sceptical I was, but I was willing to try to get my weight down and get my A1C down. First injection, no severe vomiting or anything. The only side effect I had was the constipation, I was put on a stool softener and take fiber daily, which eliminated that side effect. Within two months, I was down 15 pounds, have not given in to eating a Boston crème doughnut, on which I tend to binge, limited on my intake of food because overindulging makes me feel lousy and gives me indigestion. Within three months, my A1C is down to 5.3, and my weight is still going down. Thank you so much to the researchers who created this drug because it has saved my life and gotten me on the road to better health. The needle doesn't even hurt when I self-inject. I am grateful."

For Weight Loss (Obesity/Overweight) "My wife has been taking it since January this year and has lost just a hair over 50 lbs. It has done very well for her and the weight is staying off. The only side effects noticed so far are that it makes you very gassy, somewhat indigestion, and every now and then a little constipation."

For Weight Loss (Obesity/Overweight) "I began taking Mounjaro in November 2022. I am 61 years old, weigh 194.6 lbs, a post-menopausal female with no other health issues to note. Since then, I have lost approx. 50 lbs and feel absolutely GREAT! In addition to the Mounjaro, I took weekly B12 shots, a multivitamin, a magnesium supplement, apple cider vinegar capsules, and a chromium supplement. I took the last injection on May 2, 2023 (weighing 144.6 lbs) and have continued with supplements. After 1 month, I am weighing 146.4 lbs. I do find myself having cravings at times and could eat more, but have been able to discipline myself to continue to eat in moderation and try to be more active since I definitely feel more energetic. My goal is to maintain below 150 lbs. I am a huge fan of this drug and have experienced very few side effects while taking it. I did experience indigestion and some constipation relieved by the supplements listed above."

For Weight Loss (Obesity/Overweight) "I have been on Mounjaro for 5 months and have lost around 36 pounds so far. I was placed on it because I had high liver counts, steatosis, and pre-diabetes and was unable to exercise due to a severe case of plantar fasciitis and back and neck injuries. I started on the lowest dose and raised it to 5mg a month later, and due to a national shortage of 7.5mg, remained on the 5mg. I lost 11 pounds the first month and around 5 to 8 pounds each month after that. I feel good and have a little more energy. As far as side effects, I have had a little constipation and indigestion at times. But as long as I drank 8 to 11 cups of water a day and didn't eat high-fat fried food or sugar/sweet things, I do well. I have no complaints other than not being able to get the higher dosage because the weight loss has slowed down. Easy to inject myself also."
