For Cardiovascular Risk Reduction "I have been battling hypoactive thyroid and autoimmune disease for several years. I gained weight with hypoactive thyroid (apparently it can happen to some people) and even more with all the medication and medication side effects. My doctors decided to put me on Ozempic to aid with the uncontrollable weight gain. I have just started, it is day 6 for me and so far no side effects apart from some constipation, but this can be attributed to eating way less. I am going to be on a low dose for the first 4-6 weeks, so we started with 0.25 mg. Already a couple of hours after the injection, I had lost my appetite, I suddenly view sweets and white bread/pastries/pasta as inedible plastic, I have zero cravings, I can drink just a half a glass of water OR have just a couple of olives OR a small piece of goat cheese and I feel full (as if my stomach has shrunk into a tiny one) and do not want to eat for hours or at all, so I have reminders set that I need to have a bite. It feels amazing."

For Weight Loss (Obesity/Overweight) "I'm almost 2 meters long, and when I started, I was more than 157 kg. Within 11 weeks, I lost 22 kg. Almost every week, I lost 1.5 kg and more after the big water loss. For me, it's an addition to the bigger plan. Yes, I use Wegovy (now on 1 mg), but I also go to the gym 5 times a week and add some hour-long walks to my day. And yes, I also have a strict timeframe where I have my meals. And yes, they are mostly veggies and some yogurt with some granola for some fiber. I had some side effects like heartburn, burping, constipation, and I'm more tired than before. But I think that's a normal thing to process, especially when you make the transition. If you are seriously overweight, please consider this medicine as a small part of the bigger plan!"

For Weight Loss (Obesity/Overweight) "I've been taking Wegovy since September (2024). I initially did not like the way it made me feel. I was experiencing constipation, headaches, and nausea. My next dose was 0.50, which the pharmacy was out of until this past April 2025. I was determined to see if I could withstand the side effects. My appetite was suppressed immediately. I experienced constipation, which I counteracted with stool softeners every day. I took Zofran for the nausea. I had started riding my stationary bike around the same time that I started Wegovy. On April 17th, 2025, I started walking 30 minutes a day. I am now at a 1.7 dose. Side effects are minimal. I noticed that if I am constipated, I would get nauseous. Stay away from heavy grease. I consume a protein shake every morning and try to eat meat as much as I can as I do not really have a taste for meat or I no longer like alcohol. I am happy that I tried it again. I am 6'1" and was 283. I am 266. I want to be 240. Yay!"

For Type 2 Diabetes "I’m 63 F with T2 diabetes, and I started on Oz mid-May 2024. Symptoms: nausea, fatigue, GERD, sulfur burps, stomach cramping from severe constipation, constipation, feeling like I need to vomit, ringing in my ears has increased significantly, loss of appetite, reduction of inflammation, occasional migraines, feeling “off” most days, bouts of dizziness, and feeling faint, but blood sugar and blood pressure are normal, improved blood sugar readings, weight loss of 13 lbs. There are some perks: rheumatoid and osteoarthritis inflammation has lessened, though I still feel pain daily, it’s more tolerable. I take no painkillers but will take CBD as needed. Loss of appetite has led to a loss of 13 lbs so far, blood sugar improved so I’m confident that my A1C has improved also. I struggle with what to do: stay on for the inflammatory reductions, weight loss, and blood sugar improvement benefits, or quit because I feel sick most days, so I have no real pleasure in life anymore. No, I’m not depressed."

For Weight Loss (Obesity/Overweight) "Beginning weight was 234 and began at 0.25 in June 2024, and just began 2.4 today at 177. Been going up very slowly, but weight loss has slowed way down. Still have 17 pounds to lose, but prefer 27 more. Have gone from 2XL/Size 22 to size 14. Have dealt with nausea, headaches, occasional constipation/diarrhea, depending on what I eat. Small meals, five times a day, plus drinking lots of water is key. I get extremely tired the day or two after taking the shot. I take the shot at night, hoping to be at my goal weight by the end of May 2025. 63-year-old woman and all blood work now within normal limits."

For Type 2 Diabetes "My doctor gave me a sample box of 3 mg Rybelsus for T2D. I could only tolerate it for 10 days. The first thing I noticed was my appetite was gone. As days went on, I felt like I was in my first trimester of pregnancy, although I didn’t ever feel like vomiting. Continuous nausea, lack of appetite, lethargy, and horrible constipation were my friends during the time I took the drug and for about a week afterward. I ended up in the ER with terrible IBS with very painful cramps. I thought I had a blockage from no BMs for 12 days. After being off the drug for about a week, one day I woke up and the symptoms were gone (about a week after I stopped taking it). I felt like myself again. During that short time period, the pounds just started melting off me, and I only weighed 138 going into this. I dropped down to 130. I really wanted this drug to work for me. My doctor tried to prescribe Trulicity after this. No way. It’s too similar. My A1C is 8. Not sure where to go from here."

For Type 2 Diabetes "I took .25 for about 6 months and thought this was a miracle drug. Caused slight constipation, but I dealt with it. When they increased me to .5 mg, I started violently vomiting the next day. No one could figure out what was wrong with me. Pancreatic enzymes were high, but not high enough to diagnose pancreatitis. I could barely eat for two months. Gas, bloating, side pain, back pain, stomatitis pain, non-stop burping, constipation, nausea, vomiting off and on. My food perpetually felt like it was backed up into my mouth. They had to take me off of the drug, and now my sugars are higher than ever, and no one can help me. They were okay before, but now doctors consider me as failing two types of drug classes because of this, won't give me my old meds back, and I may have to go on insulin. I am gaining weight like never before and am so tired that I can barely function. They now believe it gave me gastroparesis, and I can't get better. I would recommend this medicine to no one."

For Weight Loss (Obesity/Overweight) "Lost 7 lbs in 7 weeks. Side effects were severe constipation and acid reflux. Happy with the results so far. But need to remember: it just curbs your food cravings. But you still have to diet/eat less to lose wt."

For Weight Loss (Obesity/Overweight) "70 pounds down and maintained for over a year now. Wegovy in conjunction with a high-protein, low-carb food plan does it right. I am convinced that the majority of negative outcomes are due to people just shooting the drug and making no changes to their diet. Stay off the sugar, keep your carb intake to vegetables and limited fruits only. Constipation avoided by adding a magnesium citrate supplement. (I use Calm)."

For Cardiovascular Risk Reduction "Working with a board-certified obesity physician who suggested I try Ozempic. I am not diabetic but was pre-diabetic in 2015 and was on 1,000 mg Metformin until February of this year. I LOVE Ozempic. I feel like a normal human who doesn't think about food constantly, who can now leave food on my plate (because of Ozempic) and not pick at other people's plates. I've lost 32 pounds in 19 weeks!! I never had any gastrointestinal problems with the exception of being constipated, so I take something for that a couple of times a week. It is much better than the diarrhea I had with Metformin. I started on .025 mg for the first four weeks, then went to .05 mg and plan to stay on that as long as it works. BUT PLEASE BE AWARE, you have to cut down on carbs like breads, pastas, and sweets. I don't have a craving for sweets anymore. My doctor said Ozempic doesn't work as well if you keep eating those kinds of carbs, and I have noticed that when I cheat. I'm 74, something about 'old dog new tricks'"

For Type 2 Diabetes "I have been taking Rybelsus for about 3 months. I have had nausea and weight loss. My blood glucose level is much better. It's even sometimes low. I now wear a continuous glucose monitor. I have random nausea after taking the medication in the mornings and can experience nausea during the day if I eat too much or greasy food. I think this is what causes some of the weight loss. You just don't want to eat if you have nausea. I do occasionally get a headache and constipation if I don't drink lots of water. The drug makes me not want to eat, but it also makes me not want to drink, so I have to force myself to drink water, or I get dehydrated and constipated. This drug makes me forget to eat or drink. It's strange. The good side effect is weight loss. Bad is nausea. My insurance does cover it."

For Type 2 Diabetes "I started in 3 mg, now in 7 mg. My blood sugars have come down enormously, I have lost about a stone in weight after being on it for 4 months. You must take it first thing with just a dash of water, don’t eat or drink for half an hour. The side effects are a bit brutal but do die down, bit of constipation and food suppression. Feel better than I have in a long while on this tablet."

For Weight Loss (Obesity/Overweight) "I started on Wegovy .25 mg mid-August and felt no side effects but no weight loss neither. Difficult stool movement right away. After 6 weeks, I started taking .50 mg after difficulty finding this dose in any pharmacy in Miami. I stayed on this dose for 4 weeks without any weight loss or bad side effects, other than constipation. Then I started taking 1 mg and immediately started feeling very bad: severe nausea and indigestion and bad diarrhea. Obviously, you can’t eat anything, so yes, I finally started losing weight, but felt so bad, I could not function, slept a lot, did not eat, was on the toilet a lot, and decided this was not worth it and stopped after two injections. Perhaps other people can deal with these kinds of side effects or they just react easier. Since I started on low doses for so long, I was disappointed the side effects were still so strong. After about three days (after stopping), I feel normal again but weight comes back quickly if you don’t have an iron will!"

For Weight Loss (Obesity/Overweight) "I started Wegovy 2 weeks ago. I have acid reflux and constipation. I took 1 magnesium/citrate gummy to help with the constipation and ended up with severe cramping with diarrhea in the middle of the night. The acid reflux happens every evening, and acid reflux meds cause constipation. I’m not enjoying the Wegovy."

For Cardiovascular Risk Reduction "I started with 0.25 at 170 lbs and was hopeful. 1st and 2nd injection, no problem, I thought, but I had gained 2 pounds, very constipated. 3rd injection, everything changed, less than 12 hours, the worst stomach cramps ever, on the stool every 20 minutes for the next 10 hours, bearing down so hard it was like labor pains. I started passing blood, and my urine became so dark it looked like apple juice. I took the last injection on Friday, that problem did not clear up until late Tuesday afternoon. I did call the doctor, he put me on antibiotics. There is no reversal for this medication. It was not for me."

For Type 2 Diabetes "I took 3 mg for 2 months and then started the 7 mg. The 3 mg I had heartburn, nausea, some diarrhea. Was uncomfortable but doable. But once on 7 mg, I had the same symptoms plus vomiting, constipation to the point of hemorrhoids, and severe heartburn to the point I almost went to the ER. I got out the label on this medicine, Rybelsus, and relooked up side effects symptoms on the computer. I immediately stopped on my own, messaging my doctor. Within 2 days, I felt so much better. This medicine is costly too, luckily I had insurance because I will not use this and it had to be disposed of. $ wasted."

For Type 2 Diabetes "25-year-old female taking Ozempic for PCOS and insulin resistance. I take Ozempic along with a strict paleo diet and workout regime. Started on 0.25 for 3 weeks with severe nausea and flu-like symptoms for the first 1.5 weeks. Felt terrible. Only remaining symptoms are constipation and upset stomach if I make a bad food choice. I have been taking 0.5 since May, Dr. not upping my dose to 1. Started taking Ozempic in April 2019 and was 193 lbs and last week weighed in at 177.4 lbs. Lots of people seem to have very severe symptoms, but I have been lucky and have not had any issues with ongoing problems or anything serious enough to skip work or end up in a hospital."

For Cardiovascular Risk Reduction "I am using it for weight loss, and so far after three months, I’ve lost 10 pounds and have really lost belly fat. I still suffer from some heartburn occasionally and some constipation, but mild compared to at the beginning. Before this, I tried everything to lose the weight I put on going through menopause, including the keto diet, intermittent fasting, and a vegan diet. I also was doing high-intensity interval training 4-6 times per week. Nothing worked until my specialist put me on Ozempic. My one concern is in regard to my fingernails, which have become quite discolored (a dark yellow) since being on the medication. Has anyone else noted this side effect?"

For Cardiovascular Risk Reduction "I have lost 20 lbs, but the nausea and constipation never went away. It did help my BP, but if you want to see the effects on your face, go outside with a mirror, and you will see the effects it has on your skin. I have always had good skin, but now I have crow's feet and wrinkles around my mouth that are much deeper than I didn’t have before. What people called Ozempic face is the same thing you get with Wegovy. The fast weight loss will leave you with loose skin also if you are older."

For Type 2 Diabetes "I have been on Ozempic for about a month, and the only problem I have is constipation, and I take stuff for it. I love my blood sugar level, it never reaches the 200 and higher range, and I love how I can't eat much anymore because before Ozempic, I would eat, but after each meal, I still would be hungry and eat some more. But since Ozempic, I can't eat a whole lot. My meal portion really went down. I no longer can eat a whole chicken breast, half of one with a small serving of cooked vegetables, and if we have a T-bone steak, half or even smaller size, I cut off and eat the rest the following day as two meals. I've lost already 15 lbs, and I feel wonderful, and I have energy again too. Can't wait to see what my A1C is next month."

For Weight Loss (Obesity/Overweight) "Have lost about 10 lbs over the last 7 months, but I had lost 30 already using a behavioral modification weight loss plan and was stuck. Doctor moved me up in doses very slowly to help me maintain lose in the long run. I am happy with this approach. Insurance covers this for me as I have high blood pressure, high cholesterol, and both parents have/had heart disease, and one parent already passed due to a heart attack and the other has already had two. My goal is to lose another 20 or so pounds and keep it off. Hoping to be able to step down the dose for maintenance. Biggest side effect has been constipation, but using OTC laxative at night and that keeps everything moving. Game-changing drug, especially having it covered by insurance."

For Cardiovascular Risk Reduction "I have been on Ozempic for 3 months now, the first day I vomited but haven’t since, nausea for the first month or so, and I got very constipated, but now all is good and I suffer no side effects anymore. So far, I have lost 22 kg, I have no sugar cravings, and my appetite is right down, making sure I eat healthy meals is the only challenge as I do not feel like eating. But I could not recommend this enough to anyone who really struggles with food and weight loss."

For Type 2 Diabetes "I’ve been taking Ozempic for a few weeks now after taking Byetta and not liking it. I also take Lantus, Humulin, Metformin, and Phentermine. I also take 2 blood pressure meds, cholesterol, nerve, and anxiety meds. I’ve had PCOS since 2000, had gestational diabetes with my youngest in 2008, and was officially diagnosed as diabetic in 2015. Last year, I had the scare of my life and went into ketoacidosis and was in ICU for a week. I have a new endocrinologist who started me on Ozempic. I started out with an A1C of 11.5 and brought it down to 7.5. I’ve lost 7 lbs so far. I have blurred vision, stumble, no appetite, constipation, no energy, insomnia, sick to my stomach, and gross belches. I feel like stuff is lodged and stuck in my chest all the time. I sure hope these side effects don’t last forever because I feel like this medicine is making my blood sugars under control for the first time in my life. I have the Dexcom G6, and it consistently checks my levels and my average is 149."

For Type 2 Diabetes "I've been on Rybelsus for a little over a month for PCOS and have had an overall positive experience - just started the 7 mg dose. My doctor recommended it since I am at risk for type 2 diabetes (>30 BMI, borderline high fasting glucose with a normal A1C, and signs of insulin resistance from PCOS). I get some pretty extreme nausea whenever I eat junk food (fatty and/or sugary), but otherwise feel good. I'm hoping that the nausea I do get helps instill better long-term eating habits. I've also experienced appetite suppression, which has helped me prioritize proteins and vegetables. I did get alternating bouts of constipation and diarrhea when starting this medicine and am expecting that I'll experience the same with the dose increase. I have felt far more energy, and my cravings for junk food have drastically reduced. So far, I've lost slightly more than 10 lbs and am shooting for another 50 to help get my PCOS under control."

For Type 2 Diabetes "I have been taking 3 mg Rybelsus since June 4th. I am not experiencing nausea nor diarrhea, however, I am experiencing constipation and loss of appetite. Since I have been taking this medication, I notice I get tired very quickly. Overall, I notice that it has helped my diabetes tremendously, and I have lost 8 lbs with very little exercise. I also take metformin 750 ER. Before starting Rybelsus, my A1C was 8.1, I do expect it to be much lower on my next visit in September."
