Exposure to certain viral infections (mumps and Coxsackie viruses) or other environmental toxins may serve to trigger abnormal antibody responses that cause damage to the pancreas cells where insulin is made. Some of the antibodies seen in type 1 diabetes include anti-islet cell antibodies, anti-insulin antibodies and anti-glutamic decarboxylase antibodies. These antibodies can be detected in the majority of patients, and may help determine which individuals are at risk for developing type 1 diabetes.
The term "type 1 diabetes" has replaced several former terms, including childhood-onset diabetes, juvenile diabetes, and insulin-dependent diabetes mellitus (IDDM). Likewise, the term "type 2 diabetes" has replaced several former terms, including adult-onset diabetes, obesity-related diabetes, and noninsulin-dependent diabetes mellitus (NIDDM). Beyond these two types, there is no agreed-upon standard nomenclature.
That is the goal of Imcyse, a French company running a clinical trial with an immunotherapy designed to stop type 1 diabetes. Patients that have been diagnosed within the last 6 months, who still retain some insulin-producing cells, are given a treatment designed to make the immune system destroy the specific immune cells that are attacking insulin-producing cells. Results are expected later this year and will reveal whether the treatment has the potential to become a cure.
In the US, 84.1 million adults—more than 1 in 3—have prediabetes, and 90% of them don’t know they have it. Prediabetes is a serious health condition where blood sugar levels are higher than normal, but not high enough yet to be diagnosed as diabetes. Prediabetes increases your risk for type 2 diabetes, heart disease, and stroke. But through the CDC-led National Diabetes Prevention Program, you can learn practical, real-life changes that can cut your risk for developing type 2 diabetes by as much as 58% (71% if you’re 60 or older).
Scientists and researchers are skeptical about the possibility of a true cure for type 2 diabetes. Michael German, a professor at the University of California, San Francisco, believes much of the success in a diabetes cure depends on an individual’s genetic makeup. And the Joslin Diabetes Center, the world’s largest diabetes research center and an affiliate institute of Harvard Medical School, claims that there is no cure for diabetes. Regardless, everyone can agree that an effective cure could put an end to the cycle of suffering for diabetes patients.
Though it may be transient, untreated GDM can damage the health of the fetus or mother. Risks to the baby include macrosomia (high birth weight), congenital heart and central nervous system abnormalities, and skeletal muscle malformations. Increased levels of insulin in a fetus's blood may inhibit fetal surfactant production and cause infant respiratory distress syndrome. A high blood bilirubin level may result from red blood cell destruction. In severe cases, perinatal death may occur, most commonly as a result of poor placental perfusion due to vascular impairment. Labor induction may be indicated with decreased placental function. A caesarean section may be performed if there is marked fetal distress or an increased risk of injury associated with macrosomia, such as shoulder dystocia.
The primary complications of diabetes due to damage in small blood vessels include damage to the eyes, kidneys, and nerves. Damage to the eyes, known as diabetic retinopathy, is caused by damage to the blood vessels in the retina of the eye, and can result in gradual vision loss and eventual blindness. Diabetes also increases the risk of having glaucoma, cataracts, and other eye problems. It is recommended that diabetics visit an eye doctor once a year. Damage to the kidneys, known as diabetic nephropathy, can lead to tissue scarring, urine protein loss, and eventually chronic kidney disease, sometimes requiring dialysis or kidney transplantation. Damage to the nerves of the body, known as diabetic neuropathy, is the most common complication of diabetes. The symptoms can include numbness, tingling, pain, and altered pain sensation, which can lead to damage to the skin. Diabetes-related foot problems (such as diabetic foot ulcers) may occur, and can be difficult to treat, occasionally requiring amputation. Additionally, proximal diabetic neuropathy causes painful muscle atrophy and weakness.
Neuropathy is one of the common effects of diabetes. It’s estimated that 60-70 percent of people with diabetes will develop some sort of neuropathy throughout their lives. By 2050, it’s estimated that over 48 million people in the United States will be diagnosed with diabetes. That means in the future, anywhere from 28-33 million Americans could be affected by diabetic neuropathy.
Keep your blood pressure under control. People with diabetes are more likely to have high blood pressure than are people who don't have diabetes. Having both high blood pressure and diabetes greatly increases your risk of complications because both damage your blood vessels and reduce blood flow. Try to keep your blood pressure in the range your doctor recommends, and be sure to have it checked at every office visit.
Chronic pain can reflect injury that hasn’t completely healed. More often, it is caused by nerves that have become oversensitive or by a brain that is misreading the signals it receives. If acute pain goes on too long, nerves and brain can tire of the constant signals and just decide the injury is permanent. That’s why it’s important to treat acute pain seriously. For example, if you injure your foot or your back and don’t treat it promptly — with adequate rest, other first-aid measures, and seeing a doctor if the pain is severe or persists — mild pain can become severe, and acute pain can become chronic.
Family or personal history. Your risk increases if you have prediabetes — a precursor to type 2 diabetes — or if a close family member, such as a parent or sibling, has type 2 diabetes. You're also at greater risk if you had gestational diabetes during a previous pregnancy, if you delivered a very large baby or if you had an unexplained stillbirth.
