Type 1 diabetes occurs when the pancreas does not produce enough insulin and is an autoimmune disease where immune cells attack pancreatic beta cells responsible for insulin production. Symptoms include increased thirst, urination, weight loss, and fatigue. It is diagnosed through blood tests showing low or undetectable insulin and C-peptide levels. While there is no cure, it can be controlled through insulin administration, blood glucose monitoring, and maintaining a healthy lifestyle. Type 1 diabetes usually develops in childhood and the body produces no insulin, whereas type 2 diabetes is associated with overweight/unfitness and the cells do not correctly respond to insulin.

2. Definition Difference: Type 1 & type 2 Treatment & Prevention Symptom & Diagnoses Cause Diabetes Type 1

3. Definition Type 1 diabetes is a chronic (lifelong) disease that occurs when the pancreas does not produce enough insulin to properly control blood sugar levels. It is an autoimmune disease, cells of the immune system attack particular cells in the pancreas — called beta cells — that produce insulin. It used to be called juvenile or insulin-dependent diabetes.

4. Causes The exact cause is unknown. However, it's possible that is may be triggered by a virus or other autoimmune diseases, or it may run in your family.

5. Symptoms & Diagnoses Symptoms : * increased thirst * increased urination * weight loss despite increased appetite * nausea * vomiting * abdominal pain * fatigue * absence of menstruation Diagnoses : Insulin test low or undetectable level of insulin C-peptide test low or undetectable level of the protein C-peptide, a by-product of insulin production Blood test - fasting blood glucose is 126 mg/dL or higher - random (nonfasting) blood glucose exceeds 200 mg/dL (this must be confimed with a fasting test)

6. Treatment & Prevention There isn't a cure for type 1 diabetes but it can be controlled with : 1. Medicines - Type 1 diabetes can be controlled by giving your body insulin. 2. Controlling your blood glucose 3. A healthy lifestyle - D iet - Physical activity - Foot care

7. Difference Type 1 Diabetes : 1. Usually begins in childhood 2. Unknown cause 3. Called juvenile or insulin- dependent diabetes 4. The body is producing no insulin Type 2 Diabetes : 1. Because they were overweight and unfit 2. Called adult or non-insulin-dependent diabetes 3. The cells do not respond correctly to the insulin 4. Pancreas still produces some insulin
