Type 2 diabetes, which is often diagnosed when a person has an A1C of at least 7 on two separate occasions, can lead to potentially serious issues, like neuropathy, or nerve damage; vision problems; an increased risk of heart disease; and other diabetes complications. A person’s A1C is the two- to three-month average of his or her blood sugar levels.
Type 1 diabetes is commonly called “juvenile diabetes” because it tends to develop at a younger age, typically before a person turns 20 years old. Type 1 diabetes is an autoimmune disease where the immune system attacks the insulin-producing beta cells in the pancreas. The damage to the pancreatic cells leads to a reduced ability or complete inability to create insulin. Some of the common causes that trigger this autoimmune response may include a virus, genetically modified organisms, heavy metals, vaccines, or foods like wheat, cow’s milk and soy. (4)
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.
