Depression May be as Risky as Obesity and Cholesterol for Your Heart

350 million people are affected by depression worldwide, according to the World Health Organisation. A new study found recently that depression may be as risky as obesity and cholesterol for your heart. “Our study shows that the risk of a fatal cardiovascular disease due to depression is almost as great as that due to elevated cholesterol levels or obesity,” said Karl-Heinz Ladwig, professor at Technical University of Munich (TUM) in Germany. Depression accounted for nearly 15 per cent of the cardiovascular deaths. “That is comparable to the other risk factors,…

Stopping Exercises in Winter Increases Cholesterol Storage: Doctors

Stopping physical exercise during the winter season increases the storage of cholesterol in the body, medical experts here said on Thursday. According to them, another reason that contributes to the cholesterol storage during winters is the lack of vitamin D synthesis from sunlight. “A decrease in sunlight pushes the body to store more cholesterol than usual as a protective measure. The seasonal variation in cholesterol levels could lead to more progression of fatty liver disease in the winter. Physical activities decrease during winters, and skipping exercise routine may be a…

High ‘Good Cholesterol’ May Not Reduce Heart Disease Risk

Raising ‘good cholesterol’ levels may not be as effective as lowering ‘bad cholesterol’ for reducing the risk of developing heart disease, a new study has found. Low and very high levels of high-density lipoprotein (HDL), known as ‘good cholesterol’ are associated with higher risk of dying from heart disease, cancer and other causes, said researchers from University of Toronto in Canada. Low level of good cholesterol may not be a heart disease risk factor on its own and also raising HDL does not likely reduce a person’s risk of heart…

Cholesterol deprivation can kill brain tumour cells

Offering new hope for an alternative treatment of brain cancer, researchers have found that depriving the deadly tumour cells of cholesterol, which they import from neighbouring healthy cells, kills tumour cells and causes their regression. “Disrupting cholesterol import by GBM (glioblastoma) cells caused dramatic cancer cell death and shrank tumours significantly, prolonging the survival of the mice,” said senior author Paul Mischel, Professor at University of California San Diego School of Medicine in the US. Glioblastoma (GBM) is the most common and most aggressive form of brain cancer, which is…

Excess ‘Good Cholesterol’ May Shorten Your Life

Too much of a good thing may not always be better for your health. Researchers have shown that high levels of high-density lipoprotein (HDL) cholesterol – commonly touted as “good cholesterol” for helping to reduce risk of stroke and heart attack – may increase a person’s risk of premature death as much as its low levels. The research suggests that intermediate levels of HDL cholesterol may increase longevity. “The findings surprised us,” said the study’s senior author Ziyad Al-Aly, Assistant Professor at Washington University School of Medicine in St. Louis,…
