Everyone experiences anxiety from time to time, but for someone with an anxiety disorder, feelings of worry and fear are overwhelming or uncontrollable — and they persist and may even worsen over time. People with anxiety may have intrusive thoughts, avoid certain situations that cause distress, and have physical symptoms like high blood pressure. An anxiety disorder is just as much a medical condition as diabetes is.
It's unclear how people get the disease — genetics plays a big role, though unknown environmental factors may also trigger the disease. Either way, the disease causes the immune system to mistakenly attack and kill insulin-producing cells, called beta cells, in the pancreas. (This differs from type 2 diabetes, in which the body initially makes sufficient insulin but the cells cannot properly use it.) Without enough insulin working to remove glucose from the blood stream, and allowing glucose to enter the body's cells, blood sugar levels spike. Left untreated, this insulin deficiency leads to a deadly complication called diabetic ketoacidosis. What's more, having high blood sugar over the long term can cause life-threatening complications such as kidney damage or heart disease, according to the Mayo Clinic.
Aside from the financial costs of diabetes, the more frightening findings are the complications and co-existing conditions. In 2014, 7.2 million hospital discharges were reported with diabetes as a listed diagnosis. Patients with diabetes were treated for major cardiovascular diseases, ischemic heart disease, stroke, lower-extremity amputation and diabetic ketoacidosis.
