Smoking and diabetes

Diabetes is a group of disease in which blood sugar levels are higher than normal. Most of the food a person eats is turned into glucose for the body's cells to use for energy. The pancreas, an organ near the stomach, makes a chemical called insulin that helps glucose get into the body's cells. When you have diabetes, your body either doesn't make enough insulin or can't use the insulin very well. Less glucose gets into cells and instead builds up in the blood.

There are different types of diabetes. Type 2 is the most common kind of diabetes in adults and accounts for about 90-95% of all diagnosed cases. Fewer people have type 1 diabetes,which most often develops in children, adolescents or young adults.
Smoking increases your chance of having type 2 diabetes. No matter what type of diabetes you have, smoking makes your diabetes harder to control.
For example, somking as well as use of other tobacco products can interfere with how your insulin works.
If you have diabetes and you smoke, you are more likely to have serious health problems from diabetes. Smokers with diabetes have higher risks for serious complications such as
1.heart and kidney disease
2.poor blood flow in the legs and feet that can lead to foot infections, ulcers and possible amputation.
3.retinopathy
4. peripheral neuropathy
If you are a smoker with diabetes and decide to quit smoking or using any type of tobacco product, the health benefits begin right away. People with diabetes who quit have better control of their blood sugar levels. Studies have shown that insulin resistance can start to decrease eight weeks after quitting. And recovery from surgery can happen faster. Don't smoke. Smoking increases your chance of having type 2 diabetes. Weight loss and physical activity can prevent or delay type 2 diabetes in adults who are at high risk for the disease.
Diabetes treatment and management can include:
1. a healthy diet and physical activity program
2. weight loss 
3. medicines to control blood sugar by helping the body use insulin better
4. insulin taken by injections or by using an insulin pump
5.patient education to address problem-solving and coping skills needed to help manage diabetes and its complications.
6.medicines to control cholesterol and blood pressure.
