Type 2 is the most common type of diabetes. According to the Centers for Disease Control and Prevention (CDC) and JDRF, there are more than <\/span><a href=\"https:\/\/www.cdc.gov\/diabetes\/basics\/type2.html\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">37 million<\/span><\/a><span style=\"font-weight: 400;\"> people with diabetes (about 90 to 95% of which have Type 2 diabetes) and about <\/span><a href=\"https:\/\/www.jdrf.org\/t1d-resources\/about\/facts\/\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">1.45 million<\/span><\/a><span style=\"font-weight: 400;\"> people living with Type 1 diabetes in the United States.&nbsp;&nbsp;<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Type 1 diabetes develops when the body no longer produces enough of the hormone known as insulin&mdash;or any insulin&mdash;to help move sugar from the bloodstream into the body&#8217;s cells to use for energy. People with Type 1 diabetes must take insulin to replace what their body can&rsquo;t produce. It&rsquo;s considered an autoimmune disease because the immune system attacks the beta cells in the pancreas that produce insulin.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Tzield works by binding to certain immune system cells and preventing them from attacking the beta cells in the pancreas, while also increasing cells that can help moderate the immune response. It&rsquo;s given by intravenous infusion once a day for 14 consecutive days.&nbsp;<\/span><\/p>\n<p><span style=\"font-weight: 400;\">People who take Tzield may experience some side effects, such as decreased levels of the type of white blood cell known as lymphocytes, headache, and rash. They&rsquo;re also advised to receive all age-appropriate vaccinations before they receive this treatment and undergo monitoring for certain symptoms.<\/span><\/p>\n<p><b>RELATED: <\/b><a href=\"https:\/\/www.singlecare.com\/blog\/type-1-vs-type-2-diabetes\/\"><b>Type 1 vs. Type 2 diabetes<\/b><\/a><\/p>\n<h2 id=\"why-type-1-diabetes-prevention-matters\"><span style=\"font-weight: 400;\">Why Type 1 diabetes prevention matters<\/span><\/h2>\n<p><span style=\"font-weight: 400;\">While fewer people have Type 1 diabetes, it tends to develop earlier in life. Type 1 diabetes can develop at any age, but it tends to appear more often within two particular windows of time: <\/span><a href=\"https:\/\/www.mayoclinic.org\/diseases-conditions\/type-1-diabetes\/symptoms-causes\/syc-20353011\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">between ages 4 and 7, and between ages 10 and 14.<\/span><\/a><span style=\"font-weight: 400;\"> By comparison, Type 2 diabetes is more commonly diagnosed after age 45, although there are growing numbers of children and teens who are being diagnosed with Type 2 diabetes.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Unfortunately, an earlier age of onset means your body will have more time to develop certain kinds of complications associated with high blood sugar levels. For example, <\/span><a href=\"https:\/\/www.singlecare.com\/blog\/diabetes-complications\/\"><span style=\"font-weight: 400;\">over time<\/span><\/a><span style=\"font-weight: 400;\">, diabetes can damage your blood vessels and even some of your nerves, causing neuropathy in your feet and hands. One serious long-term complication of&nbsp; diabetes is <\/span><a href=\"https:\/\/www.singlecare.com\/blog\/diabetic-retinopathy\/\"><span style=\"font-weight: 400;\">diabetic eye disease<\/span><\/a><span style=\"font-weight: 400;\">, which can lead to vision loss if you don&rsquo;t work hard to keep your blood sugar levels under control. Over time, people with diabetes are also more likely to develop heart disease and kidney disease.&nbsp;<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Delaying the onset becomes key to stave off those potential long-term complications. That&rsquo;s where Tzield comes in. Type 1 diabetes progresses in <\/span><a href=\"https:\/\/www.trialnet.org\/t1d-facts\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">three stages<\/span><\/a><span style=\"font-weight: 400;\">:&nbsp;<\/span><\/p>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Stage 1:<\/b><span style=\"font-weight: 400;\"> Although no symptoms are present and blood sugar levels are still normal, the body&rsquo;s immune system has started attacking the beta cells that produce insulin in the pancreas. In Stage 1, two or more diabetes-related autoantibodies are present.&nbsp;<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Stage 2: <\/b><span style=\"font-weight: 400;\">During this stage, the blood sugar levels begin to rise, due to a loss of the insulin-producing beta cells. Two or more diabetes-related autoantibodies are still present, but there are often no symptoms in Stage 2.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Stage 3:<\/b><span style=\"font-weight: 400;\"> Symptoms such as increased thirst, unexplained weight loss, increased urination, blurred vision, and fatigue may occur due to a significant loss of beta cells. Some patients are diagnosed with Type 1 diabetes when they are hospitalized with a life-threatening condition called diabetic ketoacidosis (DKA).&nbsp;<\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400;\">(Children typically progress through the three stages faster than adults do.)<\/span><\/p>\n<p><b>RELATED: <\/b><a href=\"https:\/\/www.singlecare.com\/blog\/child-type-1-diabetes\/\"><b>Your child is diagnosed with Type 1 diabetes.
