For Type 2 Diabetes "My endocrinologist prescribed 3 mg to start because the B12 depletion from metformin (I have B12 anemia) was not good and constant yeast infections from Forxiga were very annoying. At first, I noticed a major appetite decline. There was a bit of nausea for the first 2 weeks. I started the 7 mg after a month and while I've been experiencing constipation, I am so happy about the weight loss. I've been on Rybelsus for 10 weeks and have lost 10 lbs. My latest random glucose test had me at 5.7, down from 6.3 - 7 over the previous few months. I am happy about fewer carb cravings and will stay on Rybelsus as long as I can. I am lucky my health plan covers it because it's quite expensive."

For Weight Loss (Obesity/Overweight) "Nausea, diarrhea, constipation, sulfur burps, fatigue, loss of appetite, super sensitive to smells, I have to make myself eat enough. It's like morning sickness, only it's 24/7. Zofran helps for about 6 hours. Cannot tolerate much besides chicken broth and Brussels sprouts. No fried, fatty, oily, spicy foods. Need to stay hydrated with water. Ginger ale helps. I'm up to a 1 mg dose and 14th week. This nausea is constant and impacts my daily routine significantly. However, it is the only effective weight loss option that's worked in 26 years of diets and exercise and eating healthy. I will not give up. The weight is killing me, and I needed this medication. I started at 221 lbs. and now I'm at 194.3 lbs. BMI is close to pre-obesity, and I know I'll cry the day I hit it. Full disclosure, I'm disabled in part due to my weight. There is no way I could have worked and taken Wegovy with the severity of my nausea and fatigue. But the mobility and breathing issues are improving."

For Type 2 Diabetes "The first few weeks I suffered some nausea, and my food intake was reduced probably about 30% as a result. I started at 0.25 for a month, then 0.50 for a month, then 1.00, which was the full dose. I have been on the drug for about 6 months now. My weight dropped 30 pounds from 264 pounds to 234 pounds, and I seem to be leveling at that range. My target BMI weight for 6 feet 3 inches is 210, but I would be happy at 225. I have found that Ozempic did cause some constipation, but overall, once I achieved the full dose for a few weeks, I felt much better. The weight loss has really helped how I feel, and I will be doing my 6-month blood workup next week. Hoping to see some good results with glucose, which was at 6.0, and cholesterol at 259. Overall, I am very happy with the results to date."

"I’ve been on Wegovy for just over a year. At first, I experienced heartburn and a little bit of nausea and fatigue. I only threw up once. I’m adjusted to it now, and it’s keeping the weight I lost off, which was 60 pounds. I used to get migraines the day after injection, sometimes a couple of days in a row. I have found that if I take the injection earlier in the day around lunchtime and I also eat around the time I take the injection, I have fewer headaches. Please remember, you should avoid greasy foods because that causes the nausea and the heartburn, although I do enjoy an occasional hamburger. I am starting to notice a vision issue in one eye, but I don’t know if it’s related. I’m getting ready to see an ophthalmologist. I’m also in my 50s and knew already that I have the beginnings of cataracts. At first, injections cause constipation, eating better causes them to become regular for me."

For Type 2 Diabetes "My doctor put me on Ozempic to lower my blood sugar and A1c, as every time I check my blood sugar it’s extremely high in the 200s and 300s. So that is why my doctor put me on Ozempic. At the beginning of the year, before the medication, my A1c was 10.8, and my blood sugar was in the 200s. Five weeks later, I went to the doctor this week and got my sugar checked, it was 72. I couldn’t believe it, plus my A1c is 8.2, and I lost 5 lbs in just a short period. I take my shot every Sunday, .25. The day after I take the shot, I do experience some nausea, headaches, and constipation, but it’s only for one day, and it’s worth it for these low numbers. I was scared to take this new drug because I already take metformin 1000 mg once a day, but I’m so happy my doctor introduced me to this medicine. If you guys can get through the side effects, keep taking it, this medicine really works."

For Type 2 Diabetes "I've been taking Rybelsus, along with metformin and Farxiga, for over 3 months. I had some minor diarrhea/constipation with the 3 mg that worked itself out quickly, but I lost over 5 lbs and A1C went down over 1 pt (8.3 to 7.2). Just started the 7 mg dose 5 days ago. So far, the diarrhea is a lot worse, and I'm having a lot of dizziness/nausea/fatigue/headaches, but I'm hoping it'll stop soon. I seem to start feeling worse about 5-6 hrs after taking the pill, so I'm sick in bed for hours in the afternoon and evening lately. Not good, as I'm a disabled housewife with two special needs adult children who depend on me. Not sure how someone who works a 9 to 5 job would be able to handle this transition period. If it doesn't sort itself out within a couple of weeks, I'll call my doctor. One tip: keep some saltine crackers and eat a few every hour or so. I know, against diabetic diet, but that and plenty of water help the nausea."

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 A1C was slowly creeping up, and at 6.9, the Dr. wanted to start Rybelsus (3 mg). I took it exactly as directed. The side effects were immediate: constipation followed by diarrhea and extreme nausea. As I continued on the medication, nausea was constant and actually turned into stomach pain. If I ate anything, my stomach hurt worse, and I started to have an aversion to food. Any activity or exercise that involved using my core muscles was very painful. Still, I persevered knowing that it can take a few weeks to adjust to a medication. But in week 3, after side effects continued to worsen and I vomited for several days in a row, I stopped the medication. I have been off for 3 weeks now, and my stomach has not returned to normal as I have constant discomfort and it hurts after eating. I lost 10 lbs in 3 weeks, but it came at a high cost. The physical side effects were extreme, and I hope I have not permanently harmed my body. I can still only eat a few bites at any one time. Beware!"

For Type 2 Diabetes "I was a 63-year-old female when I started Ozempic. 5'2", 208#. A1C of 7.2. History of stroke, cardiovascular disease, Hashimoto's, fibromyalgia, and the list goes on. At the beginning, I had some nausea, but not terribly. I have been on it for 14 months and have lost 85#! From 208# to 125#. Average about 5#/month. When increased to 2.0, I had some issues with constipation but worked through it. Now, with a normal BMI, A1C is at 4.9 and steady. Continuing at 2.0 to maintain. I would highly recommend this to anyone! Following recent labs, my endocrinologist sent a message, 'Diabetes is in remission!' Woohoo! Good luck, everyone!"

For Type 2 Diabetes "I began taking this drug in late August 2020. It was prescribed to me by an endocrinologist to address significant weight gain over the prior two years (partially thanks to anxiety medication). The weight gain had pushed me into prediabetes, which was scary. After four and a half months, I've lost 20 lbs through reduced appetite (no real exercise). I have also seen my blood sugar levels drop. There have been occasional side effects: constipation, stomach pain, nausea. However, I have consulted my doctor, and her suggestions to manage these issues have generally helped."

For Cardiovascular Risk Reduction "I always had some side effects of Ozempic. Mainly exhaustion, nauseous, occasional throwing up after eating, constipation. As month 3 came and the dose increased to 1 mg, I ended up in the emergency room. I was vomiting and had liquid diarrhea for 4 days. My heart rate was elevated, and my potassium was dangerously low. At the time, I thought it was a stomach bug-until the next injection caused the same effects. I've been on anti-nausea medication since. I can see why it takes the appetite away-being exhausted and nauseous 24/7 is terrible. Potassium is still not where it should be. Hoping this gets out of my system fast."

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 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."

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 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."

"I have been on Metformin for many years and A1C kept climbing. MD prescribed Ozempic. Started 0.025 1x per week for 4 weeks. Really decreased my appetite. Continued 2nd month on 0.50 with no side effects. Now on max dose of 2.0 mg per week for the last 4 months and have lost a total of 25 lbs. Main problem is constipation, but once taking 1 dose of Miralax per day, eat Raisin Bran and fruit, and more veggies and lots of water, it improved. Has cleared that up. Also got the doc to prescribe Zofran for nausea, and all is great! Take the Zofran in the am and you prevent it altogether! I have never read a review where anyone said they took steps to help their side effects, so thought I'd let you know what works for me! I have gone down 2 pants sizes after losing just 25 lbs. A1C is down from 6.4 to 5.7, cholesterol and triglycerides normal. It's a game changer, just get what you need from your doc to prevent the nausea and constipation, and you will be amazed!"

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 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 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 "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 on Ozempic for 3 weeks. Yes, it is making me lose weight, obviously because I'm so nauseated all the time that I can't eat. I have stomach cramps, constipation, headaches, body aches, and nausea so severe that sometimes I can't even lift my head up. I'm really trying to give it a chance since a once-a-week injection seems better than taking a bunch of pills. I just don't know how much longer I can suffer with the terrible nausea and stabbing stomach pains."

"I started using Rybelsus in October of 2023. My starting dosage was 3 mg, and then raised to 7 mg about 4 months later. I have encountered redness, hives, and itching on my calves, scaly skin, diarrhea, constipation, nausea, cramping, and dizziness. Most of those symptoms have gone away. I take it each morning alone and do not take anything else for at least 30 minutes. When I get to work, an hour later, I take my heart and blood pressure medicine (for Afib). I gained a lot of weight for multiple reasons. The main reason was because of depression and chronic back disease. I just had lower back fusion, which has stopped my back pain. This means I can exercise now without severe pain. The good news: since I have been taking Rybelsus, I have lost 70 pounds. I now weigh 330, and by January 1, 2025, I want to be 299. It works, but does have side effects. The key is using it as directed and learning to eat smaller, healthier food portions."

For Type 2 Diabetes "2024 I am 75 years old and my doctor prescribed Ozempic for me. My A1C was 7.6 and climbing. I was overweight and could not keep the weight off even with exercise. My first dose was 0.5 mg, which I injected into my stomach. I was very sick after that - nausea and just feeling sick. So, I Googled the medication and found out I could inject it into my thigh, so I did that the next time - no symptoms this time. I have been on it for about 5 months now. My last A1C was 6.3, and I have lost weight. At times, I still have symptoms of nausea and constipation, but they go away. The worst one is low libido, and that's hard to fix. Also, muscle wasting - you must exercise to keep your muscles strong. Loss of energy might be due to eating less. I only eat small meals throughout the day. I hope this review was able to help."
