The most common types of diabetes are called type 1 and type 2 diabetes.
Type 1 diabetes patients produce low or no insulin in the pancreas, which is why insulin shots are essential for those with the disease. Type 1 can strike at any age, but it typically develops in childhood and in the late teen years.
Type 2 diabetes also produces low amounts of insulin in the pancreas—so low that the body’s cells are resistant to it. Those with type 2 diabetes also often need insulin to regulate their blood glucose levels, but they typically also require a regular regimen of healthy diet, exercise, and oral medication. Type 2 can occur at any age, but is most often seen in overweight individuals over the age of 40.
