what impact have constant weight change on our hearts?

many people suffer the so-called Yo-Yo effect, where it already taken off weight again to increase in a short time after various diets. Now, physicians found that if women in the past had to have suffered under the yo-yo effect or undergo a strongly changing weight cycle, this led to increased cardiovascular risk factors.

the scientists of the Columbia University Irving Medical Center at its current investigation found that pattern, show a subsequent weight gain (yo-yo) women on a weight loss where, to an increased risk for cardiovascular risk factors, compared with women who had a constant weight. The experts presented preliminary data from their study at the annual meeting of the American Heart Association in Houston.

obesity is as you know. If people then try to take off and her weight to resume after already a short time, one speaks of a so-called Yo-Yo effect. Exactly such fluctuations in weight increase the likelihood for heart disease in women. (Image: esolla/fotolia.com)

many women experience after a weight loss the yo-yo effect

numerous studies have already shown that maintaining a healthy weight is a good way, reduce the risk of heart disease and other chronic Diseases to reduce. More than one-third of postmenopausal women, who took part in a large national observational study, reported that the efforts were taken to remove by a rapid return to their weight before the diet to a halt. Experts describe an effect as weight cycle.

there was little studies with women on this topic

so-called weight cycles are quite common, especially for people who want to improve their cardiovascular health, explain the physician. “It is hard to draw conclusions from previous studies focused primarily on white men of middle age with heart disease history of a relationship between weight loss and cardiovascular risk some, there found, others are not”, explains the study author Brooke Aggarwal from the Columbia University Irving Medical Center in a press release. Such studies have considered not specific points in a woman’s life which usually with a weight gain are connected, such as pregnancy and menopause.

experts examined 485 women for their study of

for the current study, the physicians studied a differentiated group of 485 women aged between 20 and 76 years of age with an average body-mass index (BMI) of 26, the already is considered overweight. The women reported that she had lost at least 10 pounds within a year except during pregnancy, and then again increased. The physician then valued the heart cardiovascular health of every woman on the basis of behavior and risk factors, which had evolved from a combination of heart health, BMI, blood pressure, total cholesterol, glucose, exercise, nutrition and smoking.

women without children were more affected

more than 70 per cent of women had experienced at least once the yo-yo. 29 percent had a bad heart and cardiovascular health of those affected. In addition, these women had also a probability of 82 percent, that they were not optimal BMI. Shorter intervals the women known as weight cycles had, the worse were also their results in the study, the experts say. The effects were similar, but stronger for women who were never pregnant women before and after menopause.

further research is necessary “It is possible that a pregnancy protects the heart in a way that we currently do not understand,” says study author Aggarwal. “There’s evidence that younger women before pregnancy occurring weight cycles can prepare a future cardiovascular risk but”, the expert adds. Additional studies were now needed to determine exactly why weight cycles can negatively affect heart health for women.

some studies suggest that a reduction in muscle mass during weight loss is replaced with fat when weight is regained. An other guess is that blood pressure, blood glucose, triglycerides, and other values are increased by any weight gain many times over, Aggarwal adds. (as)
