For Type 2 Diabetes "I started Ozempic in late December at 0.25 injection. I also take 500mg metformin per day. Soon after I started Ozempic, I had decreased appetite and my sugars improved, but I had reflux, gas, bloating, nausea, and diarrhea. After 4 weeks, I started 0.50. 2 weeks in, I have bouts of painful constipation then diarrhea, nausea, bloating, gas, reflux, and cramping. I've almost vomited a few times. When I eat, it feels like the food just sits and sits, barely moving through my gut. My doctor wants me to stick with it, saying that these side effects usually improve, but it's been pretty miserable. I'm thinking I'm going to stop taking it. While Ozempic has been effective in regulating my sugars and losing weight, I don't think it's worth the suffering that I've been enduring on this medication. I understand that studies showed it causing thyroid cancer in mice, but no one knows if it causes thyroid cancer in humans. I don't want to be the guinea pig the drug makers use to find out it does."

For Type 2 Diabetes "Been on Ozempic since mid-April 2020. All side effects listed with the worst being chronic diarrhea. Nausea has been significant but has settled to occasionally. Trying to follow a more plant-based diet, I have lost today an official 60 pounds. I find the less meat I eat, the more energy I have, the better my blood sugars are as well. I am 53, so weight loss isn't impossible for us older ladies..."

For Cardiovascular Risk Reduction "I went on Ozempic for weight loss after being told by a friend of mine about it - she started at 280 lbs and lost 60+ pounds. My whole life I’ve always been about 130 pounds, and then I rapidly gained 50 pounds within about 2 years. I started taking Ozempic at 182 pounds (I’m 5’4) and 6 months later I am down 25 pounds and continuing to lose. I could not recommend this drug more. It INTENSELY reduced my appetite and obsession over food. Aside from some occasional nausea (maybe once every 2 weeks), and some diarrhea, nothing that I can’t handle, the drug has been pretty great. This is only my experience though!"

For Type 2 Diabetes "Listen to me, Ozempic will change your life, but you cannot eat synthetic sugar at all. I had severe Hashimoto's, PCOS, insulin resistance, and severe diabetes symptoms. HbA1c was high, all cholesterols were high despite the healthiest of diets. My numbers cleared from severe to perfect in 1 month! I had full-body swelling, severely cracked ankles, swollen feet, neck, legs, major hair loss... a nightmare. I began taking Ozempic. I was very sick. It made me extremely nauseous. I got severe diarrhea, but let me tell you, I lost 17 pounds of water weight in one month. My doctor couldn’t believe it. In four months, I lost 40 lbs. The nausea was mild to severe the entire time, but the results were borderline insane. It reset my metabolism, took all of the inflammation away from my joints, neck, back, my feet completely healed within one month. It’s barely believable. I spent two months on 0.25 and increased to 0.5 once a week for ten more months. High praise!"

For Weight Loss (Obesity/Overweight) "With just one 0.25 mg dose, I became very ill. Relentless nausea, vomiting, and explosive diarrhea, as well as unbearable stomach cramps. Needed to go to the ER for fluids and to check for pancreatitis. It’s now been 9 days since my first dose, and I still have relentless diarrhea, nausea, and disabling fatigue. I don’t want to eat. I didn’t want to take it in the first place but was ambushed by my kidney doctor. She told me that using Ozempic was a no-brainer and that I would just have a bit of nausea. If you have any gastrointestinal symptoms when taking any medicine, I would think three times about it before using it. I have read it can take up to a month for it to be flushed out of your body, but I am hoping and praying that these horrible side effects stop real soon."

For Type 2 Diabetes "My doctor gave me Ozempic 0.5 to start with. I always had upset stomach, diarrhea with most foods, and an overall sick feeling all the time. I was able to 'live' with it until now. She decided to up my dose to the 1.0 and my body went into total chaos. I am always nauseous, constipated, got reflux, feels like my food is stuck in my stomach and doesn't go anywhere. I'm constantly burping and feeling bloated. The sick feeling feels intensified and I cannot function at work. I took my last one this past Friday night and was miserable all weekend long. Today I am at work unable to function at my best because the nausea is bad. I would say it is effective in lowering your blood sugar numbers and helping you lose weight but not worth feeling horribly sick over. I will not be using this medication any longer."

For Cardiovascular Risk Reduction "I've been on Ozempic for just over a week now as part of a physician-run weight loss program. I was told to expect some GI upset, but I had no idea it would be this bad. Seven days after taking it, I started with diarrhea. One day after injection number 2 (2.5mg), I was up all night with diarrhea, nausea, severe reflux, belching, and eventually vomiting. Medications like Pepto can't seem to touch it. I am going to talk to the doctor next week and see what he thinks. I really don't think it is worth this kind of suffering."

For Type 2 Diabetes "Have been on Ozempic for 10 months. The first 3 months were very difficult with strong side effects. Mainly constant, but low level, nausea, occasional vomiting, and diarrhea (especially two days after the injection). However around month 3 the nausea and diarrhea subsided greatly and my appetite returned. I had lost weight very quickly (42 lbs in 3 months due to not really eating much). Had to take supplements for a while but am now eating well. The rapid weight loss led to telogen effluvium, a temporary hair loss condition. (I shed A LOT but never showed any baldness or anything). Currently, my weight is still down (I was taken off my blood pressure medication!), my blood counts are perfect, my hair is getting thick, and I eat normally. I now experience virtually no side effects. Really, really, glad I stuck out the side effects at the beginning."

For Type 2 Diabetes "I’ve been on this med for 7 weeks. I’ve lost 25 lbs and my daily blood sugars range from 60 - 90. I use it along with 500 mg Metformin. The first couple of weeks were hard with nausea and stomach cramps. I also had the headaches that others have mentioned in the first couple of days. In week 3, I increased from 0.25 to 0.50. Then came the diarrhea. It wasn't too bad, I was just happy that I could go. I’m now taking 1.0 and experiencing sulfuric burping. Ugh! After doing some research on home remedies to help with the burping, I’m trying a spoon of apple cider vinegar. If you can make it through the first few weeks and you can be somewhat disciplined, you will notice a huge difference in how you feel. In my opinion, the side effects are manageable when I compare the weight gain while taking Insulin. BTW - I’m not severely obese. Prior to being on this drug, my weight was 205, and I’m 5’9 and 47 years old. I hope this is helpful to someone."

For Type 2 Diabetes "On week 4 now, honestly, the first 2 weeks were a nightmare. Doctors don’t tell you to stay away from fatty foods and not to overeat. If they did, I wouldn’t have had the most horrible sulfur burps that made my eyes water, projectile vomiting, diarrhea, and stomach pain, not to mention constant nausea even during the night. I finally figured out not to eat too much and to avoid fatty foods completely! This was a game changer, and now I’m doing okay. I've lost 21 pounds so far, which is mad, but mostly because in 2 weeks I’ve eaten probably 4000 calories. I’m back to wanting to eat again but have to control myself or face the terrible consequences. Blood sugars are all over the place, as you can imagine, however, insulin sensitivity is way better. It just takes time to get used to. Hope this helps."

For Type 2 Diabetes "I am a 70-year-old type 2 diabetic and was taking one Metformin 500 ER for the past year or so. My A1C was 11, and it dropped to 5.6 by changing my diet and taking the Metformin. My doctor wanted me to try Ozempic to help me lose weight and possibly eliminate the Metformin. The side effects were terrible right from the start. Nausea and diarrhea, no vomiting, just nausea. I started at 0.25 and am now up to 1.0. My appetite is gone completely. I have no desire to eat at all. When I do eat, I get full almost immediately. I have gone from 228 lb down to 202 lb in the six weeks I have been taking Ozempic. I'm thrilled with the weight loss, and the nausea and diarrhea have improved. However, I have almost stopped peeing. I go in the morning, then go all day into the evening without going. Since I suffer from incontinence, it's good, but I am worried that it might be damaging my kidneys. I hope I don't have to stop taking it, at least till I lose another 50 pounds or so."

For Type 2 Diabetes "I am male (early 50s). Blood glucose was already regulated with metformin, diet, and exercise (100 to 150), but I wanted to quit metformin because of its side effects (diarrhea). I was put on 0.50 mg/wk and warned that nausea from Ozempic was a common side effect. I had no idea! Week 1/Week 2: I couldn't smell food without getting queasy. I choked down lots of soup just to get 1200 cal/day (often falling short). Week 3/Week 4 got slightly better. Week 5: I have my appetite back. I feel full, so I eat smaller meals. My weight loss is atypical: 203 lbs to 183 lbs in five weeks, combined with exercise (1 hr/4x wk stationary bike/treadmill). Blood glucose is now between 90 and 120, with occasional dips and peaks. I would only recommend this drug to those who have very high glucose levels, are morbidly obese, fiercely stubborn, and/or desperate. But it works. Good luck."

For Type 2 Diabetes "I've been on Ozempic for 2.5 months now (10 weeks as of today) off-label for PCOS. I started with a dose of 0.25 for the first four weeks and have been on 0.5 for the remaining six. On the 0.25 dose, I felt my appetite was slightly reduced, and I had some mild nausea. As soon as I went to 0.5, the side effects started, and I began getting extreme nausea, diarrhea, rancid burps, and I can no longer eat. If I eat more than a regular ham and cheese sandwich in a day, I feel extremely nauseous and the burps come back. As of my last doctor's appointment, I've lost about 3 pounds, but I don't know if I can keep this up. I'm miserable. I won't know until next month whether it's working like my doctor has intended because she needs blood tests to verify all of that, so I can't speak to how effective it has been yet."

For Type 2 Diabetes "I was moved to Ozempic from Januvia. At the time I started Ozempic, I'd brought my blood sugar down to what would translate to an A1C of 5.5 or so, and I'd managed to kick most of the insulin I was on. I started Ozempic at 0.25 units per week and had mild nausea and diarrhea, but my appetite vanished and I could barely bring myself to eat. Once I started the full dose, my blood sugars began to climb rapidly. I'd be fine in the mornings at first and then experience wild spikes between meals, until finally, my fasting sugar started to climb out of my desired range. I actually had to take MORE insulin, not less, just to keep my fasting BG below 7. Ozempic was absolutely NOT worth it - even with the lower price here in Canada, the cost is ridiculous, the benefits never materialized, and the effects on my appetite destroyed the healthy diet I was trying to eat. Good example of how new isn't always good."

For Type 2 Diabetes "A1C was 6.2 with Metformin. Went on Ozempic for 3 months. I had side effects of bad nausea, vomiting, and watery diarrhea. Lost 27 lbs. Couldn't eat 4/7 days. My A1C now 5.6, and it is not worth it for me."

For Type 2 Diabetes "I started taking this 3 weeks ago. I didn’t really have any terrible side effects other than fatigue, but after my third injection, nausea, diarrhea, and stomach pain hit me with a vengeance. I feel like I ate rotten eggs. I’m not sure I want to continue taking this. I might try injecting it in my thigh like some others have tried. I hope it works because my glucose readings have been in the 90s to 120."

For Type 2 Diabetes "Started Ozempic about 7 weeks ago. Dosage .25. First week noticed some nausea, a lot of gas, some reflux, and diarrhea. Each week, side effects were getting worse. Nausea very bad, pains in left side, waves of heat, no energy at all. In all, just feeling BAD! Diarrhea is bad and a bit uncontrollable. Have not raised dosage due to being afraid of worse side effects. Have lost 5 pounds. Appetite is definitely less. My sugar numbers have not improved that much, which leads me to believe it is what I am eating. I still crave sweets. I have some jittery feelings at times! I am very discouraged."

For Type 2 Diabetes "First injected dose Sunday night. Wee hours Monday, the nausea started. No vomiting (emetophobic here!) Monday all day nausea that I could handle (took a Zofran). Tuesday afternoon hit with sudden stomach cramping and diarrhea. Those nasty sulfuric burps all Tuesday evening and overnight, diarrhea all night, and now it’s Wednesday morning and still watery diarrhea. My stomach has been rumbling and terribly bloated since Tuesday afternoon. I need to lose 70 lbs, but this is NOT worth it!! Who wants days and weeks of feeling HORRIBLE!?! I’ll lose weight another way! I have sleep apnea and am 56, so I want to be healthy, but this drug is not recommended unless you need to lose weight to stay alive. I teach too, so there’s no way I can continue this."

For Type 2 Diabetes "I started taking the Ozempic injection a week before Christmas and took my second 0.25 dose on Xmas Eve. I've felt slight nausea since taking it and very little desire to eat. My BS levels have been 95% in range ever since and have managed to reduce my long-acting insulin by 20 units. I have lost 6 lbs so far. I was astounded it came off in the first week. The only time I have had bad stomach pains is when I've eaten something bad, and I get terrible runs 20 mins after eating, but once I've been to the loo, pain stops. I had vomiting once because I think I overate a few days after taking it. I was super bloated, and a few hours later I threw up, then I felt fine again. So I just eat little and often, mostly grazing and picking at fruit. I was worried about taking this because of the comments I've read, and with having IBS, I didn't know if it would be bad for me. But I have no issues taking it, and so far, so good. It's still early days for me, but I would 100% recommend it."

For Cardiovascular Risk Reduction "Warning, this stuff will make you sick. I have been taking this for 2 months. In the first month, I had terrible diarrhea. It got so bad I ended up going to the hospital. I told my doctor, and he said he doubted it was Ozempic, so I tried it again in the 2nd month on a higher dose, and the 2nd week in, again I was terribly ill, vomiting for 4 days straight with intermittent diarrhea and feeling absolutely awful. My night sleep is very broken with stomach pains, increased wind, nausea. I'm now stopping using it."

For Type 2 Diabetes "My A1C had gone up as high as 8.0, and my doctor kept adding medications to my arsenal of drugs to control my diabetes. I was taking so many drugs but was getting terrible side effects, including kidney stones, liver enzymes over 600, diarrhea, nausea, and finally, I was hospitalized and taken off all my drugs, but then my diabetes was out of control. Finally, my GI specialist recommended starting with Ozempic .5, and that's when everything started to change. At first, I didn't see much change in my weight loss, so my doctor raised it to 1mm. It was then that I saw my A1C go down to 7.2, and I had lost 10 pounds without trying. Now I have been taking Ozempic for over a year, and my A1C is down to 6.7, and I dropped 20 pounds. I don't have any side effects unless I overeat, which I avoid. If I overeat, I get an uncomfortable feeling in my stomach, but within a short period, it subsides. I wish my mother would have had the ability to get Ozempic 10 years ago, maybe she'd be alive today."

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."

Next dose, the symptoms increased, especially the loose stool, lasted most of the day for 4 days. The next dose, the doctor had me go to .5, and I say OMG, it was the worst I have ever felt. Couldn't eat, watery diarrhea, burping horribly, tired, and just felt so sick. I told my doctor I can't do this. Symptoms still going after being off for a week and a half. I just hope it stops soon. I do not recommend it to anyone."
