Diabetes And Eye Health

Diabetes is a disease that affects the body’s ability to produce or use insulin effectively to control blood sugar (glucose) levels. Although glucose is an important source of energy for the body’s cells, too much glucose in the blood for a long time can cause damage in many parts of the body, including the heart, kidneys, blood vessels and the small blood vessels in the eyes. When the blood vessels in the eye’s retina (the light sensitive tissue lining the back of the eye) swell, leak or close off completely — or if abnormal new blood vessels grow on the surface of the retina — it is called diabetic retinopathy. People who are at greater risk of developing diabetic retinopathy are those who have diabetes or poor blood sugar control, women who are pregnant, and people with high blood pressure, high blood lipids or both. Risk also increases with duration of diabetes. For example, one woman developed diabetic retinopathy after living with diabetes for 25 years. Also, people who are from certain ethnic groups, such as African-Americans, Hispanics and Native Americans, are more likely to develop diabetic retinopathy. In fact, a new study confirms that diabetes is a top risk f Continue reading >>

    "Hey OP sorry I didn't read through the thread so not sure if anyone mentioned this but I used to take regular metformin 500mg 2x per day but like you I would be on and off cause it literally made me so sick and tired. But recently my new doctor recommended metformin extended release. I swear it's been a life changer for me. I take 500 mg per day and I've been losing weight and it doesn't make me feel sick at all! I've also been taking biotin simultaneously which has increased my overall mood and energy, not to mention my hair and nails have been growing too!"

    "Hi, I've been on Metformin off and on for years. I had no idea it was supposed to help with weight. Honestly, when I was diagnosed with PCOS in 2009 my doctor made it sound like I just needed to lose weight and it would go away. I was also 21 and had no idea how to advocate for myself. When I walked out of the Dr.s office I thought I was informed on everything I needed to know. So as I'm reading these posts I'm shocked! I've been sitting at 220lb for years. I do Crossfit, I eat well and my job is very active. I naively got off of Metformin because of the nausea and bowel discomfort I was experiencing. I've never given it more than a month. I started taking it again 3 days ago. 850mg twice a day. I'm encouraged and hope to see some changes"

    "I have been on metformin for 6 months at 500mg and I've only lost 7 pounds. First off, I'm 5'9 and 152 pounds. I started at 159 pounds. My goal is to get to 140lb and get pregnant considering that's what my doctor suggested. I have tried everything to loose weight, I literally ate lettuce and excercised like crazy prior to trying metformin, nothing worked. I even looked at liposuction. I didn't have any diarrhea, sometimes when I ate too much I felt nauseous on the medication. However, the medicine helps curb your appetite. I barely ate anything. Maybe I had eggs in the morning, no bread. Lunch soup with salad and at night nuts and yogurt. I can't believe I only lost 7 pounds. I'm still NOT pregnant, yet I do I have regular periods."
