For Type 2 Diabetes "My A1C and glucose levels are great. I am not on insulin. Side effects are rotten. Nausea, GERD, constipation/diarrhea, headache, stomach pain, decreased appetite every shot lessens over the week. Had this with Ozempic and Trulicity too, but not as severe. I have seen no weight loss benefit despite a decent diet and moderate exercise 3-5 times per week. Other side effects I’m not sure are related: feeling of lump in throat, slight face rash, occasional blurred vision, tingling in hands."

For Type 2 Diabetes "I finished the first four weeks of 2.5 mg injections last week. Tonight, I start taking the 5 mg injection. I have had dizziness and lightheaded episodes that come and go, and occasional blurred vision. Constipation has been a problem. When I have dizzy spells, the top number of my blood pressure is lower than normal. My appetite has changed, I don't eat as much as I did before, and my weight has dropped thirteen pounds since I first started taking it. I see my doctor in two months, that's when I'll find out if it is helping my A1C. My doctor informed me that it would help me lose weight, which I need to do very much. It's very easy to use."

For Type 2 Diabetes "I have been taking Mounjaro for almost three months, increasing the dosage each month according to my doctor's prescriptions due to my Type 2 diabetes. I have experienced dizziness, constipation, lack of appetite, blurry vision, and nausea after eating a meal. None of the side effects I've experienced have been severe enough to warrant discontinuing Mounjaro. My A1C has dropped from 8.5 to 6.3, and I have lost 30+ pounds since starting Mounjaro. I have not experienced diarrhea, vomiting, or pancreatitis. I am pleased with Mounjaro, which has resulted in weight loss and diminishing A1C levels."

For Type 2 Diabetes "I have been on Mounjaro since Sep 2022. I started off with the 2.5 mg for about a month with no issues. My provider then moved me to 5 mg in October. Once again, no issues, and I started losing weight. 15 lbs in about 6 weeks. I was then moved up to 7.5 mg in November and have been miserable ever since. I have no appetite, severe constipation, major headaches, and vomiting, and I am now having issues with low blood pressure (causing lightheadedness, dizziness, and vision issues), which I believe is being caused by my never wanting to eat or drink anything. I have informed my provider of this, and she is now wanting to send me to a cardiologist to make sure my heart is working properly. She has also decided to lower my dosage back to 5 mg. I am hoping this change helps because so far, my type 2 diabetes is under control, and my sugars have been fantastic!"

For Type 2 Diabetes "I was diagnosed with type 2 diabetes in May 2025. My doctor prescribed Mounjaro as I also was a bit overweight with high BP. Started at 2.5 mg. Initial reaction was stomach pain and nausea that subsided within the first couple of weeks. I also had some constipation. After a month, my doc increased me to 5 mg. Stomach pain came back but not as bad, then subsided by month 2. Weight loss at 12 weeks was 20 lbs. BP was lowered. Overall I was feeling well, eating better, feeling less pain, even from my fibromyalgia. Started my fourth month on Mounjaro (3rd month at 5 mg) and within a day I felt very off balance, blurry vision in my right eye, headache on right side. Mid of month 3 I had some major right upper back pain and she ordered ultrasounds. Now a CT scan of my head. Waiting results."
