Type 2 diabetes is often treated with oral medication because many people with this type of diabetes make some insulin on their own. The pills people take to control type 2 diabetes do not contain insulin. Instead, medications such as metformin, sulfonylureas, alpha-glucosidase inhibitors and many others are used to make the insulin that the body still produces more effective.
In addition to the problems with an increase in insulin resistance, the release of insulin by the pancreas may also be defective and suboptimal. In fact, there is a known steady decline in beta cell production of insulin in type 2 diabetes that contributes to worsening glucose control. (This is a major factor for many patients with type 2 diabetes who ultimately require insulin therapy.) Finally, the liver in these patients continues to produce glucose through a process called gluconeogenesis despite elevated glucose levels. The control of gluconeogenesis becomes compromised.
Doctors and scientists are investigating a potential cure for diabetes. This involves transplanting insulin-producing cells into the body of a person with diabetes. Researchers are also testing ways to stop diabetes before it starts. For example, scientists are studying whether diabetes can be prevented in those who may have inherited an increased risk for the disease.
There are a number of rare cases of diabetes that arise due to an abnormality in a single gene (known as monogenic forms of diabetes or "other specific types of diabetes"). These include maturity onset diabetes of the young (MODY), Donohue syndrome, and Rabson–Mendenhall syndrome, among others. Maturity onset diabetes of the young constitute 1–5% of all cases of diabetes in young people.
Type 1 diabetes occurs when your immune system, the body’s system for fighting infection, attacks and destroys the insulin-producing beta cells of the pancreas. Scientists think type 1 diabetes is caused by genes and environmental factors, such as viruses, that might trigger the disease. Studies such as TrialNet are working to pinpoint causes of type 1 diabetes and possible ways to prevent or slow the disease.

Diabetic neuropathy (nerve damage). This makes it hard for your nerves to send messages to your brain and other parts of the body. You may lose feeling in parts of your body or have a painful, tingling, or burning feeling. Neuropathy most often affects the feet and legs. If you have neuropathy, you may not be able to feel a sore on your foot. The sore can become infected. In serious cases, the foot may have to be amputated (removed). People who have neuropathy may continue walking on a foot that has damaged joints or bones. This can lead to a condition called Charcot foot. Charcot foot causes swelling and instability in the injured foot. It can also cause the foot to become deformed. However, this problem can often be avoided. Check your feet every day. See your doctor immediately if you see swelling, redness, and feel warmth in your foot. These can be signs of Charcot foot. Your doctor should also check your feet frequently. Neuropathy also can cause erectile dysfunction in men and vaginal dryness in women.
Up to 40 percent of people with type 2 diabetes eventually develop kidney failure — the kidney's inability to filter waste and fluid from the blood, according to the National Kidney Foundation. As blood flows through tiny vessels in the kidneys, waste products are filtered out and leave the body through urine. Too much sugar in the blood can stress these filters, making it hard for the kidneys to work effectively. After a while, the filters can break down and leak protein into the urine. If kidney damage continues, you may need dialysis or a kidney transplant.
Hyperglycemia or high blood sugar is a serious health problem for diabetics. There are two types of hyperglycemia, 1) fasting, and 2)postprandial or after meal hyperglycemia. Hyperglycemia can also lead to ketoacidosis or hyperglycemic hyperosmolar nonketotic syndrome (HHNS). There are a variety of causes of hyperglycemia in people with diabetes. Symptoms of high blood sugar may include increased thirst, headaches, blurred vision, and frequent urination.Treatment can be achieved through lifestyle changes or medications changes. Carefully monitoring blood glucose levels is key to prevention.
Type 2 DM begins with insulin resistance, a condition in which cells fail to respond to insulin properly. As the disease progresses, a lack of insulin may also develop. This form was previously referred to as "non insulin-dependent diabetes mellitus" (NIDDM) or "adult-onset diabetes". The most common cause is a combination of excessive body weight and insufficient exercise.
What medication is available for diabetes? Diabetes causes blood sugar levels to rise. The body may stop producing insulin, the hormone that regulates blood sugar, and this results in type 1 diabetes. In people with type 2 diabetes, insulin is not working effectively.
