But researchers found that obese individuals with type 2 diabetes who had weight-loss surgery were roughly 35% less likely to experience problems like heart attacks, strokes, and heart failure, and they were less likely to die during the study. They also lost more weight, controlled their diabetes better, and reduced the amount of medication they took.

Obese patients who undergo bariatric surgery—better known as weight loss surgery—may reduce their likelihood of developing skin cancer, a new study has suggested.

The study, led by researchers from the University of Gothenburg in Sweden and published last week in JAMA Dermatology, found that obese patients who underwent procedures like gastric bypass or gastric band surgery to help them lose weight were less likely to develop skin cancer, including melanoma.

The research used data derived from observations of 4,047 obese adults who belonged to a study cohort known as the Swedish Obese Subjects; 2,007 patients underwent bariatric study, while 2,040 did not have surgery but "received the customary treatment for obesity" from their doctors.

We All Gain Weight When We Age, And This Study Explains Why

We All Gain Weight When We Age, And This Study Explains Why New research says lipid turnover in fat tissue decreases during aging and makes it easier to gain weight, even if we have always been eating and exercising the same amount. Over an average of 13 years, scientists observed the fat cells of 54 men and women. Regardless of whether they gained or lost weight, their fat tissue experienced a slowing in lipid turnover. Lipid turnover refers to the rate at which that fat in fat cells are removed and stored.

Researchers found that the surgery patients were significantly less likely to have developed skin cancer during the period between their enrollment in the study and the follow-up, an 18-year window on average.

This phenomenon did not appear to be influenced by how obese subjects were compared to other members of the cohort, nor was it influenced by how much they drank or if they smoked. If they had had surgery at all, their likelihood of skin cancer was reduced.

The study's subjects were mostly (71 percent) female, with an average age of 48 years old.

There are several types of gastric surgery, but according to the U.S. National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), two of the most common in the United States—and the ones which some of this study's Swedish subjects underwent—are gastric bypass and banding.

Through exercise and diet, April lost 280 pounds in three years. "I really don't remember a time not being overweight," she says looking back, saying she was always labeled "the fat kid" growing up and felt "doomed" to be overweight her entire life. While pregnant, she says she used it as an excuse to overeat and when her daughter was born, she hit a real low point when she was unable to get up and walk with her daughter as she took her first steps due to her weight. "My body was just too heavy," she says. "It was a breaking point.

In gastric bypass, a surgeon staples part of a patient's stomach to form a small pouch in the upper part of the organ. The surgeon then attaches the patient's small intestine to the pouch, allowing food to "bypass" most of the stomach. As a result, the patient's stomach has less room for food and becomes full sooner leading the patient to eat less.

"The bypass also changes gut hormones, gut bacteria, and other factors that may affect appetite and metabolism," according to NIDDK.

Surgery involving a gastric band works similarly, but involves a surgeon inserting "a ring with an inner inflatable band" around a person's stomach to achieve the effect of making the stomach smaller. This was the variant of the surgery most of the Swedish test subjects received.

A third type of surgery patients in the Swedish study received, vertical banded gastroplasty, uses both a staple and a band to make the stomach smaller, according to Johns Hopkins University.

Vitamin A May Help Stave Off Skin Cancer, According to a New Study

  Vitamin A May Help Stave Off Skin Cancer, According to a New Study The study found that increased vitamin A intake was associated with a lower risk of developing squamous cell carcinoma.The study itself examined a lot of people over a long period of time; more than 48,000 men and 75,000 women over 26 years. After controlling the study to account for other health indicators, such as basic lifestyle factors and skin cancer risk, researchers found that increased vitamin A intake (from diet) was associated with a lower risk for developing SCC.

More research into the relationship between weight loss, weight loss surgery and skin cancer will be necessary to show causality and to verify whether the findings are replicable, as the cohort used for the Swedish study was not necessarily representative of a larger population.
