Too much is too bad for pregnancy

Spending too much time in the gym could negatively affect your chances of having children, a new study says.

The researchers from the Norwegian University of Science and Technology say ‘superwoman work-outs’ can increase the risk of having fertility problems three-fold. The study showed that younger women were more vulnerable to having such problems.

The researchers found that those who exercised most, a quarter couldn’t conceive during their first year of attempting compared to the national average of seven per cent. They suggest that extreme exercising deprives the body of energy needed for a successful pregnancy.

“We found two groups who experienced an increased risk of infertility,” said Sigridur Lara Gudmundsdottir.

“There were those who trained almost every day, and those who trained until completely exhausted. Those who did both had the highest risk of infertility,” Sigridur added.
However, the negative effects of a punishing routine were not permanent.

Obesity, cause for several cancers

Over 1,00,000 types of cancers are caused by obesity, according to an American study.
Excess body fat makes a person vulnerable to cancer by increasing the amount of hormones like estrogen circulating in the body and disrupting how the body processes insulin, which is linked to higher risk of cancer.

It also triggers low-grade inflammation in the body, which is increasingly being found to play a role in cancer.

Researchers from American Institute for Cancer Research suggest that people should maintain a normal body weight and remain physically active throughout life.

Kidney function linked to heart

Poor kidney function may increase an individual’s risk for suffering heart failure, heart attack, peripheral arterial disease and early death, reveals a new study.

Researchers revealed that to evaluate heart health, clinicians should look at their patients’ current level of kidney function and also changes in kidney function over time.
During that study, Dr Michael Shlipak, University of California, and Dr Mark Sarnak, Tufts-New England Medical Centre, examined elderly people with help of new blood test of kidney function, called cystatin C.

They looked for links between changes in kidney function during a period of seven years with the incidence of heart failure, heart attack, stroke, and peripheral arterial disease (obstruction of large arteries in the arms and legs) during the subsequent eight years.

Chemicals affect cholesterol levels

A new study has revealed that chemicals used in commercial and industrial applications such as surfactants, paper and textile coatings and food packaging might affect serum cholesterol levels in people.

The polyfluoroalkyl chemicals (PFCs) have been found to be highly persistent in human tissues, with serum elimination half-lives of more than eight years for some types of PFCs.

During the study, researchers analysed the relationship between serum concentrations of four PFCs-perfluorooctanoic acid (PFOA), perfluorononanoic acid (PFNA), perfluorooctane sulfonic acid (PFOS) and perfluorohexane sulfonic acid (PFHxS)-and measures of cholesterol, body size and insulin resistance.
