Urinary incontinence is the involuntary leakage of urine; in simple terms, to wee when you don't intend to. It is the inability to hold urine in the bladder because voluntary control over the urinary sphincter is either lost or weakened.
By Mayo Clinic Staff. The exact cause of type 1 diabetes is unknown. In most people with type 1 diabetes, the body's own immune system â which normally fights harmful bacteria and viruses â mistakenly destroys the insulin-producing (islet) cells in the pancreas.
The two main types of diabetes are type 1 and type 2. In type 1 diabetes, the body doesn't make enough insulin. This causes the body's blood sugar level to rise. In type 2 diabetes, the body's cells don't use insulin properly (a condition called insulin resistance). At first, the body reacts by making more insulin.
