Type 2 Diabetes is a chronic (lifelong) disease marked by high levels of sugar (glucose) in the blood. Type 2 diabetes is the most common form of diabetes.

Alternative NamesNoninsulin-dependent diabetes; Diabetes - type 2; Adult-onset diabetes
Causes, incidence, and risk factorsDiabetes is caused by a problem in the way your body makes or uses insulin. Insulin is needed to move blood sugar (glucose) into cells, where it is stored and later used for energy.
When you have type 2 diabetes, the body does not respond correctly to insulin. This is called insulin resistance. Insulin resistance means that fat, liver, and muscle cells do not respond normally to insulin. As a result blood sugar does not get into cells to be stored for energy.
When sugar cannot enter cells, abnormally high levels of sugar build up in the blood. This is called hyperglycemia. High levels of blood sugar often trigger the pancreas to produce more and more insulin, but it is not enough to keep up with the body's demand.
People who are overweight are more likely to have insulin resistance, because fat interferes with the body's ability to use insulin.
Type 2 diabetes usually occurs gradually. Most people with the disease are overweight at the time of diagnosis. However, type 2 diabetes can also develop in those who are thin, especially the elderly.
Family history and genetics play a large role in type 2 diabetes. Low activity level, poor diet, and excess body weight (especially around the waist) significantly increase your risk for type 2 diabetes.
Other risk factors include:
Often, people with type 2 diabetes have no symptoms at all. If you do have symptoms, they may include:
Type 2 diabetes is diagnosed with the following blood tests:
You should see your health care provider every 3 months. At these visits, you can expect your health care provider to:
The following tests will help you and your doctor monitor your diabetes and prevent complications:
The immediate goal of treatment is to lower high blood glucose levels. The long-term goals of treatment are to prevent diabetes-related complications.
The primary treatment for type 2 diabetes is exercise and diet.
LEARN THESE SKILLS
You should learn basic diabetes management skills. They will help prevent complications and the need for medical care. These skills include:
It may take several months to learn the basic skills. Always continue to educate yourself about the disease and its complications. Learn how to control and live with diabetes. Over time, stay current on new research and treatments.
SELF-TESTING
Self testing refers to being able to check your blood sugar at home yourself. It is also called self-monitoring of blood glucose (SMBG). Regular self-testing of your blood sugar tells you and your health care provider how well your diet, exercise, and diabetes medications are working.
A device called a glucometer can provide an exact blood sugar reading. There are different types of devices. Usually, you prick your finger with a small needle called a lancet. This gives you a tiny drop of blood. You place the blood on a test strip and put the strip into the device. Results are available in 30 - 45 seconds.
A health care provider or diabetes educator will help set up an at-home testing schedule for you. Your doctor will help you set your blood sugar goals.
The results of the test can be used to adjust meals, activity, or medications to keep your blood sugar levels in an appropriate range. Testing can identify high and low blood sugar levels before serious problems develop.
Keeping a record for yourself and your health care provider. This will be a big help if you are having trouble managing your diabetes.
DIET AND WEIGHT CONTROL
People with type 2 diabetes should eat at about the same times each day and try to be consistent with the types of food they choose. This helps to prevent blood sugar from becoming extremely high or low. Meal planning includes choosing healthy foods, eating the right amount of food, and eating meals at the right time. You should work closely with your doctor, nurse, and registered dietitian to learn how much fat, protein, and carbohydrates you need in your diet. Your meal plans should fit your daily lifestyle and habits, and should try to include foods that you like.
Managing your weight and eating a well-balanced diet are important. Some people with type 2 diabetes can stop taking medications after losing weight (although they still have diabetes).
See: Diabetes diet
Bariatric (weight loss) surgery may be considered for very overweight patients who are not well managed with diet and medications.
See:
REGULAR PHYSICAL ACTIVITY
Regular exercise is important for everyone, but especially if you have diabetes. Regular aerobic exercise lowers your blood sugar level without medication and helps burn excess calories and fat so you can manage your weight.
Exercise can help your overall health by improving blood flow and blood pressure. It decreases insulin resistance even without weight loss. Exercise also increases the body's energy level, lowers tension, and improves your ability to handle stress.
Consider the following when starting an exercise routine:
MEDICATIONS TO TREAT DIABETES
If diet and exercise do not help maintain normal or near-normal blood glucose levels, your doctor may prescribe medication. Since these drugs help lower your blood sugar levels in different ways, your doctor may have you take more than one. These drugs may also be given along with insulin, if needed.
Some of the most common types of medication are listed below. They are taken by mouth or injection.
If you continue to have poor blood glucose control despite lifestyle changes and taking medicines by mouth, your doctor will prescribe insulin. Insulin may also be prescribed if you have had a bad reaction to other medicines. Insulin must be injected under the skin using a syringe or insulin pen device. It cannot be taken by mouth.
Insulin preparations differ in how fast they start to work and how long they work. Your healthcare provider will determine the appropriate type of insulin to use and will tell you what time of day to use it.
More than one type may be mixed together in an injection to achieve the best blood glucose control. Usually injections are needed one to four times a day. Your doctor or diabetes educator will show you how to give yourself an injection.
Some people with type 2 diabetes find they no longer need medication if they lose weight and increase activity. When they reach their ideal weight, their own insulin and a careful diet can control their blood glucose levels.
It is not known whether hypoglycemia medications taken by mouth are safe for use in pregnancy. Women who have type 2 diabetes and take these medications may be switched to insulin during pregnancy and while breastfeeding.
MEDICATIONS TO PREVENT COMPLICATIONS
Since those with diabetes have a much higher chance of developing Heart disease, kidney disease, and other medical problems, they may need to take certain medicines to treat these problems or prevent them from happening.
An ACE inhibitor (or ARB) is often recommended:
ACE inhibitors include captopril (Capoten), enalapril (Vasotec), quinapril (Accupril), benazepril (Lotensin), ramipril (Altace), perindopril (Aceon), and lisinopril (Prinivil, Zestril).
Statin drugs are usually the first choice to treat an abnormal cholesterol level. Aim for LDL cholesterol level less than 100 mg/dL (less than 70 mg/dL in high-risk patients).
Aspirin to prevent heart disease is most often recommended for persons with diabetes who:
FOOT CARE
People with diabetes are more likely to have foot problems. Diabetes can damage nerves, which means you may not feel an injury to the foot until a large sore or infection develops. Diabetes can also damage blood vessels.
In addition, diabetes affects the body's immune system. This decreases the body's ability to fight infection. Small infections can quickly get worse and cause the death of skin and other tissues. Amputation may be needed.
To prevent injury to the feet, check and care for your feet every day.

Expectations (prognosis)The risk of long-term complications from diabetes can be reduced. If you control your blood glucose and blood pressure, you can reduce your risk of death, stroke, heart failure, and other complications. Reduction of HbA1c by even 1% can decrease your risk for complications by 25%.
ComplicationsAfter many years, diabetes can lead to serious problems with your eyes, kidneys, nerves, heart, blood vessels, and other areas in your body.
If you have diabetes, your risk of a heart attack is the same as someone who has already had a heart attack. Both women and men with diabetes are at risk. You may not even have the typical signs of a heart attack.
In general, complications include:
Other complications include:
Call 911 immediately if you have:
These symptoms can quickly get worse and become emergency conditions (such as convulsions or hypoglycemic coma).
Call your doctor also if you have:
Diabetes screening is recommended for:
You can help prevent type 2 diabetes by keeping a healthy body weight and an active lifestyle.
To prevent complications of diabetes, visit your health care provider or diabetes educator at least four times a year. Talk about any problems you are having.
Stay up-to-date with all your vaccinations and get a flu shot every year.

pathophysiology of diabetes mellitus type 2
Type 1 diabetes
Type 2 diabetes is a type of diabetes where the individual is not fully dependent on insulin. A type 1 diabetic requires insulin.
The types of Diabetes are type 1 with sub type -brittle diabetes, type 2 and juvenile diabetes, type 3 (under research) , and Gestational diabetes during pregnancy.
you know what my dad has type 2 diabetes and the type one is way way way worse. type one can kill you but when i was three my dad had type 2 diabetes and it is OK and did you know if your mom or dad had diabetes you are at risk of getting type 2 so say your dad or mom has type one diabetes you are at risk of getting it but if your mom or dad had type 2 diabetes you are at risk of getting type 2 - hope this helped alot
Insulin is the hormone that is imbalanced in type 2 diabetes. In type 2 diabetes, insulin resistance results in the production of increased, but ineffective, insulin.
No but you can get Type 2 Diabetes.
There is NO type of 'good' diabetes, but the one your looking for is probably type 1 diabetes. People are usually born with that type. Type 2 diabetes is the one people get if they're overweight, don't exercise, and they eat junk all the time.
absolutely. There are 2 kinds of diabetes. Type 1 and Type 2.
diabetes are two type 1insulin dependent diabetes 2 non insulin dependent diabetes
the not so bad diabetes is called type 2 diabetes
There are multiple types of diabetes. Type 1 may also be referred to as jchildhood diabetes. Type 2 is also referred to as adult onset diabetes. The number of children with type 2 is increasing.
