If you believe that smoking affects only the lungs, then you may be wrong as a new study showed that components in cigarette smoke may directly damage the muscles in your leg as well.

According to the researchers, smoking could directly damage the muscles by reducing the number of blood vessels in leg muscles, which in turn reduce the amount of oxygen and nutrients the muscles received.

“It is vitally important that we show people that the use of tobacco cigarettes has harmful consequences throughout the body, including large muscle groups needed for daily living, and develop strategies to stop the damage triggered by the detrimental components of cigarette smoke,” said lead author Ellen Breen from the University of California-San Diego, US.

Under a mouse model, a team of researchers from California along with Universidade Federal do Rio de Janeiro in Brazil and Kochi University in Japan, exposed the mice to smoke from tobacco cigarettes for eight weeks, either by inhalation or by injecting them with a solution bubbled with smoke.

The results, published in The Journal of Physiology, also showed that the reduced level of oxygen and nutrients due to reduced blood vessels may impact the metabolism and activity levels.

Both these are risk factors for many chronic diseases including chronic obstructive pulmonary disease (COPD) and diabetes.
The study, however, could not identify the chemical responsible out of the 4,000 chemicals in a cigarette smoke that caused the muscle damage.

Researchers said that further study is needed to identify them, along with understanding the process by which they reduce the number of blood vessels. (IANS)

Gaining Weight After Quitting Cigrattes, Still Better In the Long Run: Study

Regardless of the amount of weight gain, quitters always have a lower risk of dying'' prematurely.

If you quit smoking cigrattes and gain weight, it may seem like you’re trading one set of health problems for another. But a new U.S. study finds you’re still better off in the long run.

Compared with smokers, even the quitters who gained the most weight had at least a 50 percent lower risk of dying prematurely from heart disease and other causes, the Harvard-led study found.

The study is impressive in its size and scope and should put to rest any myth that there are prohibitive weight-related health consequences to quitting cigarettes, said Dr. William Dietz, a public health expert at George Washington University.

“The paper makes pretty clear that your health improves, even if you gain weight,” said Dietz, who was not involved in the research. “I don’t think we knew that with the assurance that this paper provides.”

The New England Journal of Medicine published the study Wednesday. The journal also published a Swedish study that found quitting smoking seems to be the best thing diabetics can do to cut their risk of dying prematurely.

10 pounds or more

The nicotine in cigarettes can suppress appetite and boost metabolism. Many smokers who quit and don’t step up their exercise find they eat more and gain weight — typically less than 10 pounds (4.5 kilograms), but in some cases three times that much.

A lot of weight gain is a cause of the most common form of diabetes, a disease in which blood sugar levels are higher than normal. Diabetes can lead to problems including blindness, nerve damage, heart and kidney disease, and poor blood flow to the legs and feet.

In the U.S. study, researchers tracked more than 170,000 men and women over roughly 20 years, looking at what they said in health questionnaires given every two years.

The people enrolled in the studies were all health professionals, and did not mirror current smokers in the general population, who are disproportionately low-income, less educated and more likely to smoke heavily.

The researchers checked which study participants quit smoking and followed whether they gained weight and developed diabetes, heart disease or other conditions.

Quitters saw their risk of diabetes increase by 22 percent in the six years after they kicked the habit. An editorial in the journal characterized it as “a mild elevation” in the diabetes risk.

Studies previously showed that people who quit have an elevated risk of developing diabetes, said Dr. Qi Sun, one the study’s authors. He is a researcher at the Harvard-affiliated Brigham and Women’s Hospital.

But that risk doesn’t endure, and it never leads to a higher premature death rate than what smokers face, he said.

“Regardless of the amount of weight gain, quitters always have a lower risk of dying” prematurely, Sun said. (VOA)
