Type 1 diabetes stems from the immune system's failure to combat cells that produce insulin in the pancreas, which stops the body from producing insulin, while type 2 diabetes creates an insufficient amount of insulin for the body, according to MedicineNet.com. Type 2 diabetes derives from such factors as obesity.
MedicineNet.com notes that the body accidentally creates damaging cells in the case of type 1 diabetes, which attack beta cells that produce insulin. Experts believe that genetics plays a role in inheriting these negative cells.
Mayo Clinic notes that cells that degrade immune cells are known as auto-antibodies. However, not everyone who has auto-antibodies develops type 1 diabetes. The exact cause of type 1 diabetes remains unknown, but genetics and a person's environment may play a role. For instance, one theory is that a person can get type 1 diabetes from a viral sickness, although scientific evidence is not clear on this.
MedicineNet.com reports that type 2 diabetes occurs when the pancreas produces larger amounts of insulin than usual. The cells' insensitivity to insulin is another major aspect of the type 2 disease.
Mayo Clinic claims that people are more likely to get type 2 diabetes if they have excessive fatty tissue, which causes the cells to resist insulin. A person who is less active stands a higher risk of getting type 2 diabetes as well. Triglycerides are fats in the blood that are associated with type 2 diabetes in high amounts. High cholesterol and blood pressure can also influence the development of type 2 diabetes.
