For Type 2 Diabetes "I started taking metformin late November of 2014, and with my weight and height, I was considered obese. I am 5 foot 4" and I weighed 204 pounds before taking the medication. My A1C was at seven and one-half at the time of my blood test. Since taking metformin 2 times a day, 500 milligrams each time, I have lost close to 20 pounds. Along with the change in my eating habits, I'm feeling much better and continuing to lose weight on an amazing scale!"

For Insulin Resistance Syndrome "When I first started taking this medication, it was horrible. I had extreme fatigue, stomach cramping, abnormal bowel movements, and even threw up blood a few times. Despite all of this, I lowered my dosage but stayed on the medication, and I've never felt better. After around 3 weeks of that, I started feeling normal and dropping weight. I'm down 25 lbs combined with only a healthy diet. It suppresses my appetite, but not enough to cause any harm. I am on 500mg 2x a day. Give the medication a chance, a lot of people have to take it for a couple of months for it to work properly."

For Polycystic Ovary Syndrome "I was diagnosed with PCOS at 14, and I was always on birth control until this year. Now I am 27. I went in to my OB/GYN and asked to get on metformin to regulate. I was prescribed 500mg four times a day. Sure enough, my periods came like clockwork, and I was late this month. I took a test and got the BFP (A big fat positive pregnancy test). After taking it for 6 months, I finally conceived. I did not know this was a miracle pill. I tried for so many years, and now my prayers were answered. Don't give up, ladies. There is hope. I am passing on baby dust to all of you... :)"

For Type 2 Diabetes "Took Metformin 500mg twice a day for 5 weeks and I really wanted to stay on it because my insurance covered the total cost. By the second day, I developed diarrhea. Daily trips (more than 10) to the bathroom increased because of bad diarrhea. I took the medicine with a meal that included bread, but the extreme diarrhea persisted. Weight dropped from 196 to 189 lbs. Had a problem with increased thirst and constant dry mouth. Glucose still increased to 255. Alternated taking Pepto Bismol and Imodium AD for days trying to control diarrhea. I was concerned about leaving home because of the severe diarrhea. I started to feel dizzy. My mood became negative and I wondered if absorption of my antidepressant was being affected. Finally, after the 5th week of Metformin twice a day, I informed my PCP about all my side effects. He had me stop the Metformin and put me on 10 mg of Jardiance. The diarrhea, severe thirst, dry mouth, dizziness, and bad mood all stopped. 59-year-old female."

For Insulin Resistance Syndrome "I have low testosterone, high blood pressure, and overweight (291 lbs) for the past 20 years. I started Metformin in mid-January and worked my way up to a dose of 2000mg per day. As of today (May 27, 2020), I have lost a total of 53 pounds and it has reduced my appetite by more than half. My blood pressure is starting to drop to the point of needing to have my meds adjusted. I am mountain biking again. I am feeling great. I have some of the side effects, but they are minimal. All my issues seem to have a connection to insulin resistance. I suggest doing your own research and talking to your doctor. Based on my research online, it seems this amount of weight loss is highly unusual."

For Type 2 Diabetes "A month ago, I was placed on Metformin ER 500 mg twice a day after being diagnosed with Type 2 diabetes (HbA1C of 7.9). I, like so many on this forum, experienced violent diarrhea for the first 7 to 10 days, which then suddenly ceased. For the first time in my life, I have since experienced life as someone without a weight problem. I no longer think about food ruminatively, have to remind myself to eat, and I stop eating when full (eating smaller portions than previously). I have not had my blood glucose re-tested yet so cannot speak to the effectiveness of Metformin for glucose control, but I expect much improvement, even at this subclinical dose. I have been losing 2 to 3 lbs per week without much effort. It has been life-changing."

Metformin for Insulin Resistance Syndrome "So far, I have been on Glucophage for 2 1/2 weeks for Insulin Resistance due to Polycystic Ovarian Syndrome. I had a little nausea and diarrhea the first two days. By day three or four, I had no more negative side effects. It worked very quickly, I quickly began to lose weight and started menstruating again. My skin also began to clear up within the first week. Glucophage helps so many of the terrible issues caused by PCOS. I need more time to better evaluate the medicine, but so far it is like a miracle. If it is taken with food, the side effects are negligible."

For Insulin Resistance Syndrome "My endocrinologist put me on Metformin for what he diagnosed as metabolic syndrome. My general physician sent me to him because he thought I was pre-diabetic. My triglycerides were through the roof... 3500 at one point! Prior to starting Metformin I had worked on improving my diet, watching calories and quality of foods I ate and I had seen some moderate weight loss. Once on the Metformin, my triglycerides dropped 90% (from 3500 to 350) and the pounds began to drop away... several pounds every few weeks to the point that I am down 42 pounds (from 220 down to 178) in about 4 months. All while still battling my alcohol consumption at 7 to 10 beers a night (99 calories each) which is 750 to 1000 calories per night."

For Type 2 Diabetes "Metformin has side effects like diarrhea. When I have sugar (regular sugar, fructose, and artificial sugar - it does not care), I get diarrhea. Also, headaches occur if sugar spikes quickly - again, food choices do this. If I really want a bite of pizza or a candy bar, I eat healthy (lots of vegetables and salad, protein) with no processed foods, no bread, pasta, potatoes, or rice. At the end of the meal, I have 1-2 bites, savor it, and stop. I give myself a treat once a month. I keep my sugars down to 80-130 by diet and one Metformin 500mg a day. If I eat too much at a meal, I walk or exercise to burn the carbs. Burning too much results in feeling shaky or getting a headache. Water is key too. Water helps pull sugar down (dilutes and flushes it out of the fat cells)."

Metformin for Type 2 Diabetes "Metformin (Glucophage generic) works very well without any side effects (maybe a small bit of diarrhea and gas - but that helps get rid of my constipation). I am NOT overweight. In great shape with running, playing tennis and golf, etc. Age 65. Never was overweight. Got diabetes from drinking way too much Coca Cola and eating too much sweets (donuts, cake, candies, etc.). Always burned off the sugar so never put on weight. Never knew sugar was a poison that affects metabolism. Started taking metformin (3 X 800 daily dosage two years ago). With diet changes, brought down my blood glucose level from 358 to 130, and A1C from 15.9 to 6.7. Not out of the woods yet, but huge improvement, and metformin is the only drug that works for me."

Metformin for Type 2 Diabetes "I've had Type 2 Diabetes for a few years, and have gained over 100 lbs. I have been on Metformin for a month and have lost 28 lbs. Glucophage is amazing, but I will admit at first I was very sick. After about a week, I started to feel normal again."

For Polycystic Ovary Syndrome "Started taking Metformin 2 weeks ago, 1500mg daily to treat PCOS. Periods have improved significantly. Leg and back pain has completely disappeared, and I have lost 10kg since starting Metformin. I didn't even manage to lose 1kg in 3 months while on a low-calorie diet, so that's great. My mood is much better, and my facial hair and acne seem to have also disappeared. I feel like a completely different person on this medication."

For Insulin Resistance Syndrome "Been on metformin for a month. Only the first two days had a bad headache. When I started taking it, I was 102kg heavy. Now I'm 94kg. But when I was diagnosed with insulin resistance, I quit alcohol, sugar, and lactose. Started working out more. My endocrinologist told me to also take vitamin D and vitamin B12, so I guess that also helped. I have literally no side effects. I haven't felt happier and healthier in my life."

For Type 2 Diabetes "I have been taking Metformin ER for 10 years. It was working fine. Recently, the supplier was switched from Teva to Amneal. I found Amneal to cause high blood sugar, and I discontinued. I switched to another supplier, and my blood sugar is normal. I found out today that Amneal is recalling Metformin ER in 7 lots. I was taking a recalled lot. The recall is for a higher level of carcinogenic contamination in these lots. Please report any adverse effects."

For Type 2 Diabetes "(54) yr old male: Metformin worked very quickly to lower my blood glucose levels from almost 400 to progressively down to an average of 130 within 10 days. My only complaint is the side effect of very noticeable BLURRED vision and soreness around my eyes. I have always been blessed to have 20/20 vision, so this is not something I am used to. I am willing to deal with this side effect as long as my glucose levels are back to normal. As we all know, a lifestyle change with regard to diet and exercise is a MUST. My situation was a 'wake-up call', and my plans are to eventually be weaned off Metformin within 6 months. Be encouraged and don't give up."

For Insulin Resistance Syndrome "OK, so I am prediabetic and on Day 4 of metformin. So far so good. My energy levels increased. Slight reduction in appetite. I hope this keeps up. I'd like to lose weight and found it a challenge with my insulin spiking throughout the day. I'd get hungry, craving starchy foods in the later part of my days, which made it difficult to keep up with my diets. With metformin, I don't think of food as much. I am more mindful of my food intake."

For Polycystic Ovary Syndrome "I found out I had PCOS in 2013 after trying to get pregnant for 3 years! I had started to gain weight slowly over the course of a year, about 25 lbs. My doctor started metformin in August of 2014 and by September, I dropped 10 lbs, and by December a total of 28 lbs. I'm 5'2" and that brought me back to about 128 lbs, a healthy weight! I found out in February of 2015 I was pregnant!!! I had a healthy baby boy in October 2015, and I believe it was metformin!!!"

For Polycystic Ovary Syndrome "My husband and I were trying to have a child for seven years, and we had no success. I was diagnosed with PCOS, and I was put on Metformin. Four months later, I was pregnant. It was such a wonder for us, as I had two cycles of Clomid (unsuccessfully). I hope this will help someone else because infertility can be heartbreaking."

For Polycystic Ovary Syndrome "I appear to be in the minority, but I have had no negative side effects on Metformin and have nothing but good things to say about it. This cured the awful physical effects I was experiencing due to insulin resistance and prediabetes (blurred vision, high heart rate, brain fog, constant hunger, and cravings) and has allowed me to finally exert some control over my body. I experience no nausea or changes in stool. It has been a magic pill for me. Helped me lose a significant amount of weight, and my mental health is better than it has been in years. Finally, I feel like myself again. Like a magic pill for me."

For Polycystic Ovary Syndrome "This is my first time writing a review. I'm doing this today to share my experience with you, beautiful ladies, who are having difficulties conceiving due to PCOS. I'm 31. My period has been irregular since I was 14. Sometimes I don't menstruate for a whole year. I was misdiagnosed at first, and in 2015, I had a proper diagnosis which happened to be PCOS. My husband and I got married in 2014, and since then, we started trying to conceive with no luck for one year. My OBGYN put me on metformin 500mg daily. I took it for three months, my period never came, and I talked to my endocrinologist. She increased my dose gradually to 2500mg max. Two weeks later, my period came, and the following month, I got pregnant with my daughter! She's 8 months and 2 weeks."

Metformin for Type 2 Diabetes "I started Glucophage XR on February 20. I cannot believe how much better I feel. Before Glucophage, I spent every waking minute thinking about what I would eat next. For the last 5 years, I stayed under 1000 calories a day, and my readings were 175 or 83. I was up and down like a yo-yo all day and night. I gained weight constantly. I weighed in at 196 lbs on Feb 20. Now, 2 months later on Glucophage, I have lost 29 lbs, and I eat like a normal person. I cannot believe the difference. The first week on it, I had some nausea, but it went away, and I now have no side effects. I keep thinking this is a fluke, a pill cannot make that much of a difference. I feel better than I have in 20 years. I now have energy because I am eating enough, and my readings are amazing."

For Type 2 Diabetes "I'm a 62-year-old male. Some years back, I was experiencing a very dry mouth and frequent urination. I had my blood sugar level measured, and it was at 350, so I was prescribed Metformin. The Metformin brought my sugar level down to about 150 but gave me a very bad upset stomach. The nausea wasn't temporary for me. It didn't clear up even after taking the Metformin for weeks. However, I did find a solution to the problem. I switched from the regular fast-acting Metformin to the extended-release Metformin XR. The difference was like night and day. I have had no nausea at all using the Metformin XR. If you're having stomach problems using regular Metformin, I suggest trying the extended-release version. I now take 2000 mg of Metformin XR daily."

For Polycystic Ovary Syndrome "I was diagnosed with polycystic ovarian syndrome 2 years ago. Unfortunately, it took several doctors and a 150-pound weight gain for someone to realize what was going on. During the 2 years since I was diagnosed, my doctor has had me try everything, and nothing has helped. Finally, she decided to give me metformin. I've been on it for 10 days now. I'm currently only up to 1000 mg, but I've already lost 5 pounds. I've hardly had any side effects. Also, my facial hair growth has slowed, and I'm breaking out less."
