Semaglutide and Diarrhea: What Users Say

For Type 2 Diabetes "I started taking Rybelsus at the beginning of August for weight loss. The biggest con for me is that it causes constipation and then usually diarrhea when I finally do go to the restroom. I have only had issues with nausea when I try to eat past the point of being comfortable. It is also important to try to eat something within an hour of taking the medication. When I first started on the medicine, I could only eat a few bites of food and then would feel extremely full and bloated and would have to stop. Now, it is 4 full months later, and I am on the 14mg, and I can continue to eat beyond a few bites without feeling miserable, but I try to stop as soon as I am full. I have, so far, lost 30 lbs with no exercise and have gone from a size 12/14 to a size 6/8. Diabetes does run in my family, so I am hoping continued use of this drug may help prevent the development of diabetes in the future."

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 Type 2 Diabetes "It’s been a week on Rybelsus 3mg. I feel pretty good (except for seasonal allergies). No nausea, no vomiting, no diarrhea, smaller appetite. I am prediabetic with BMI >30. I would like to lose 30 to 40 pounds. I think Rybelsus will help me. (Prior to taking Rybelsus, I was fasting (16-hour/8-hour) and exercising EVERY day and STILL gaining weight.) I think Rybelsus will help. I weigh daily, and I am beginning to see the numbers ever so slightly trend down. I am optimistic. I will start 7mg after 30 days. I hope to come back here and share my journey with you."

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) "Took it for 8 weeks, made it through the 2nd titrated dose and couldn't handle it anymore. Nausea, gas, bloat, constipation, diarrhea, and it was worse at night while lying down. Never improved, but actually got worse by week 8. Not sure how anyone makes it to the full dose. Also did not drop a single pound. There were days I only consumed 600 calories and still felt awful. I read another review very similar and agree that you absolutely cannot eat anything spicy. Bland food days were better but there are not enough antacids and constipation meds in the world to make me want to lose 20 pounds this badly. Took my last dose 10 days ago and am still dealing with residual GI upset. Hope physicians are more forthcoming about the side effects and do not tell patients they happen but subside in a couple of days - they do not."

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 "I started taking Rybelsus 3mg. I was nauseous at first and constipated. I was also belching a lot. After 2 weeks, that seemed to stop. I've been on the 7mg for 17 days and the nausea, indigestion, stomach pain, and now diarrhea have been almost unbearable and are getting worse. I've also started feeling panicky and anxious in the middle of the night with rapid heartbeat. I'm stopping the 7mg tomorrow and calling my doctor. I can't feel like this at Christmas. Going to see if she will put me back on 3mg. My A1C was 9.0. I have no idea what it is now. I've also lost 18 lbs because I can barely eat anything. This isn't worth it."

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 "I’m prediabetic, HbA1c 5.7. And I’ve been struggling to lose weight for 20 years. I have an excellent diet, but I eat too much. I’m hungry all the time. I started Rybelsus (paying out of pocket - Ouch) to see if it’s worth hassling my insurance company. On 3 mg, I felt nothing - no nausea, but experienced loose stools. When I went to 7 mg, I felt nausea for 1 hour after taking the pill and decreased appetite the rest of the day. I am easily staying on my 1400-1500 calorie diet, which has never been easy for me in the past. At 1 month of 7 mg, I’ve lost 8 pounds (255 to 247) and feel very encouraged. The science behind this medicine is inspiring."

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 "My doctor put me on Rybelsus as I had high blood sugar. I had too much difficulty taking the 3 mg with nausea, diarrhea, and headache. I planned to quit, but I read the reviews here. I somehow managed my symptoms and tried harder. My doctor then increased the dosage to 7 mg. Rybelsus was able to bring my blood sugar levels from 10.6 to 5.6, almost normal levels in a period of 3 months. If anyone is planning to quit, please persevere, and the results are amazing. It practically stops your cravings for food and helps you stabilize. Another miracle was that I was finally able to quit coffee in the morning as I get migraines without it. Compared to the nausea, diarrhea, and the churning of the stomach, migraine wasn't a big deal, and I finally went without taking coffee. This is really a miracle drug for diabetes. Thank you."

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 "Was placed on this medication to help with PCOS-caused insulin resistance and obesity. The first two months were a bit uncomfortable - I was nauseated a lot and had bouts of constipation and diarrhea. Fortunately, immediately starting it, my sugar cravings disappeared. I think I had a rough couple of months because of my old eating habits since this medicine slows how fast your stomach empties. As I developed better eating habits, this has gone away completely. I’ve been on this for almost a year now and have lost almost 60 lbs. I’m about 5 lbs away from being a normal weight and I’m barely making any effort at this point; the weight is just coming off. I feel the healthiest I’ve felt in over a decade and have been seeing my PCOS symptoms reduce as the weight comes off. This medicine was a miracle for me. I’ve struggled for a decade trying to get my weight under control. Once the insulin resistance was resolved, it literally fell off."

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 Weight Loss (Obesity/Overweight) "I started Wegovy in April 2024. I was 193 lbs at just between 5’1”-5’2.5. I had tried everything, but food noise and the fact that being so short, the calorie intake had to be so low to lose weight. Anyway, the first thing I noticed was a bit of nausea. That went away after a few days. I have had very minimal side effects. Sometimes a little nausea, constipation, or diarrhea. Nothing to really disrupt my life. For the first time in my life, I actually can tell when I am full. My IBS has been almost non-existent. I’m more awake. I have fewer sweet cravings. The food noise is still there, but my stomach is able to signal my brain that if I eat more, I will feel sick. I have lost to date 4/2024-3/2025, 63 lbs. I am just about to hit my normal weight goal. I knew how to lose the weight. I am someone who has a very difficult time shedding the weight with exercise and diet. I am super grateful for this opportunity to prove that a drug works so well."

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 Weight Loss (Obesity/Overweight) "Started Wegovy 3 months ago using the gradual phase-up method. From 0.25 mg dose for 4 weeks to 0.50 mg dose for 4 weeks, then 1.0 mg dose for 4 weeks. During the initial phase, I experienced mild nausea and some stomach irritation. With each increase, the symptoms got worse until finally, at the full 1.0 mg dose, I was so sick I thought I had stomach flu for 2 weeks continuously. The belching was horrible. The nausea caused uncontrollable vomiting, and I had frequent diarrhea. After 3 months, I lost 12 pounds and felt horrible every day. I've now reduced the dose to 0.5 mg but still suffer from nausea and stomach upset. I might cut back again, but I'm thinking I will quit. The way I feel all the time is horrible! I'm thinking I lost weight because of all the vomiting. Not recommended."

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 "My endocrinologist prescribed this to help with PCOS. I weighed 211 lb and started on 3 mg and lost 6 lbs while walking for 2 miles a day most days for a month. I was bumped up to 7 mg, but insurance wouldn't cover it, and I ended up gaining the weight back after trying Victoza and Byetta. My insurance changed, and my endocrinologist started me back on it at 7 mg since I already had Byetta in my system. During this time, I found out I have Ehlers-Danlos and was recommended to start weight lifting to help strengthen my muscles and lost 13 lbs in a little over a month, which I'm sure exercise has helped contribute. My menstrual cycle has been regular and on time for the first time in 4 years. I haven't had any major side effects other than a little nausea when I first take it in the morning and diarrhea, but I had that issue beforehand. I know a lot of people have said the side effects are terrible, but it hasn't been for me, and you should certainly give it a try. It's honestly been wonderful."
