For Type 2 Diabetes "I started Ozempic 9 months ago. At the time, I was a little over 200 lbs and was taking 1000 mg of metformin daily. Metformin had worked for me for almost 20 years, so I didn't expect that it had suddenly stopped working. For 3 years, I gained weight even though I worked out, and I thought it was just my appetite out of control. One random day, I realized my metformin was the problem. I saw a new doctor who prescribed Ozempic. What a miracle! 9 months later, and I’m down 40 lbs, my A1C dropped from 8.1 to 5.6, and I have virtually no symptoms from the drug other than fullness. The symptoms in the beginning did not last long either. Nausea, headache, fatigue...all cleared up within a week or 2 each time my dose was increased. It can cause what feels like constipation, but for me, it’s just that I simply haven’t eaten enough. This drug feels too good to be true. I’m so pleased with my experience so far!"

For Weight Loss (Obesity/Overweight) "I was prescribed Ozempic for weight loss in Nov 2022. I started on 0.25 mg for one month. I found it slightly suppressed my appetite, and the side effects I had were awful heartburn, constipation, and sulfur burps. Sometimes I felt nauseous. I decided to stick with it anyway and increased to 0.5 mg after one month. The symptoms were the same but added in fatigue. A month later, I bumped up to 0.75, and the burps, fatigue, and heartburn subsided. I went to 1 mg two months later, and all symptoms disappeared. I started at 192 lbs on Nov 15th, and as of May 1st, I weigh 152 lbs. I found my sugar cravings disappeared once I started taking 1 mg. Up until then, I still craved sugary foods. I lost all interest in greasy food (fries, anything deep-fried, etc.) from 0.5 mg and up. I personally love Ozempic. The side effects at the beginning were worth it for me, but from the sounds of it, mine weren’t that bad. I have never once thrown up."

For Weight Loss (Obesity/Overweight) "I had high hopes for this drug and stuck with it as long as I could, but it caused severe constipation, stomach cramping, and fatigue. I started out with .25 mg for 4 weeks, then .50 for 2 weeks. I didn’t lose weight, so my doctor increased the dose to 1 mg, but I just couldn’t tolerate the side effects at the lower doses, so I didn’t even try the 1 mg."

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 "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."

For Type 2 Diabetes "I did not have a good experience with Ozempic. Other than a 35 lb weight loss in 4 months, there is nothing else good I can say about it. From the first dose, I’ve had nausea and dizziness. The second dose has been a rollercoaster of constipation, stomach pain, fatigue, with continued nausea and dizziness. I’m constantly sick, I can’t eat anything more than a couple of bites of food. Nothing tastes the same, and the smell of food makes me head to the bathroom with nausea. So going out to eat is only a memory now. I do not recommend this medication. This cannot be healthy for anyone. I’ve stopped taking the Ozempic and am wondering if these side effects will end, they say it takes 5 weeks to leave your system. I’m counting the days!!"

For Type 2 Diabetes "I experienced severe stomach bloating and constipation after the first dose. I started injecting into the back of my arms and, with each subsequent dose, side effects lessen, though I still experience moderate nausea and fatigue after taking my weekly dose. On the positive side, my appetite has been reduced by at least 1/2, with 15 pounds lost. My fasting blood sugars are in the 80's and my post-meal levels rarely top 130. Even after eating small amounts of carbs, sugars fall to the nineties within an hour."

For Type 2 Diabetes "On the plus side, Ozempic quickly began to lower my blood sugar, which metformin alone was no longer able to do, despite exercise & diet control, so that I was back into more normal numbers. I still take metformin. I had some constipation, but worked through that issue & mild nausea also appeared, but then disappeared. My overeating for stress & or boredom was much easier to manage, I thought about eating poor choices & then was able to push the thought away. The biggest challenge was fatigue, I often am feeling very sluggish & sleepy & have to push through chores like grocery shopping. I’ve lost 5 lbs in 2 months & want to lose 15 more lbs to achieve my goal, so I hope the fatigued side effect will diminish. Easy to learn how to administer from the instructions. I’m on 0.5 dosage & believe I will increase to 1 dosage within the month."

For Type 2 Diabetes "I am a 68-year-old male with Type 2 diabetes. I tried Ozempic .025 low dose, to also lose weight. Have been on it for 5 weeks and have had an upset stomach and constipation since the beginning. Only lost 6 lbs. To me, the side effects of always feeling sick and not hungry, which for me led to tiredness and fatigue, even though I take vitamins, is definitely not worth it. Blood sugar went down below 100 for the first 3 weeks but has gone back to upper normal, 140-150 since then. Not worth it to feel sick all the time. I am quitting this stuff."

"I underwent lap band surgery several years ago and am currently taking Ozempic. If given the option, I recommend choosing Ozempic over lap band surgery due to their similar side effects. However, if it is possible to manage diabetes and weight with an alternative medication, I suggest doing so. It's important to administer the injection in the thigh, as other injection sites tend to cause worse side effects. The side effects of Ozempic are persistent and severe, and unfortunately, they are unpredictable. One week you may experience minimal side effects, while the next week, at the same dosage, the side effects may be so severe that you will need to miss work. Ozempic causes extreme fatigue, unlike any other fatigue I have experienced. My eyes struggle to stay open. Additionally, I have suffered from intense constipation for two weeks with minimal relief from laxatives, followed by a few days of uncontrollable diarrhea and acid reflux. I no longer enjoy food; it no longer tastes good, and fruit or tea is no longer refreshing or soothing. I believe there must be a balance between enjoying food and weight loss."

For Type 2 Diabetes "My doctor put me on this because I was pre-diabetic, and he said I was insulin resistant. Since I’ve been taking it, I’m not as hungry, but my head hurts, and I always feel dehydrated, and so I’m peeing all day. I feel short of breath, and my chest has been feeling pains. I’m also experiencing constipation and constant light-headedness, and I’ve only been on it for 2 weeks. I may give it another 2 weeks, but not sure if the side effects are worth all this. I feel no energy, and my legs are always sore, and I’m so tired all the time. My way of living has suffered because I’m too tired to do anything and feel yuck all the time. Trying not to be frustrated because if this doesn’t help me, he wants to put me on Jardiance, but I hear so many horror stories about that one. This one isn’t as great as everyone said it would be, so who knows, maybe Jardiance will be better for me."

For Weight Loss (Obesity/Overweight) "So far, so good. Six weeks on. Constipation's been an issue. Definitely has cut my appetite down, and I lost my taste for my weekend beer and have a glass of wine or two. Everything else has been fun. Little fatigue I’ve noticed, but hopefully I continue to lose weight."

For Type 2 Diabetes "Have been on Ozempic for about 2-3 months at 0.25. Experienced/experiencing: nausea, heartburn, fatigue, light-headedness, constipation. Nausea has calmed down but still occurs. Heartburn has developed over the last month and is definitely not subsiding. Seems I am always tired. Sometimes getting up, I become light-headed and off balance. Constipation is quite prevalent even with eating high fiber fruit and vegetables, and I am doing my best to drink plenty of water, starting with hot lemon water and honey every morning. I do not know if I would recommend this drug or not. Everyone is different. Thank you."

For Type 2 Diabetes "I started Ozempic in January 2022. First week, I had extreme diarrhea with blood and mucus (always constipated before this). Endocrinologist told me he didn’t think it was Ozempic, but I went off it. Diarrhea, etc., continued. Ended up having to get a colonoscopy and was diagnosed with Ulcerative Colitis. Endocrinologist wanted to put me back on Ozempic. We figured the diarrhea, etc., was just the colitis. Started it back up five weeks ago. No diarrhea, back to constipation, nauseous every day, extreme fatigue. Also now diagnosed with Retinal Vasculitis. But my inflammatory markers are high. Not sure if this all started because of Ozempic. Just increased to 0.5 mg today, so we will see. It just seems like an odd coincidence. No appetite, but no weight loss either. Hair loss, but could be from colitis."
