Smoking and obesity are both independently associated with faster disease progression in multiple sclerosis (MS), but when both risk factors are present together, a synergistic effect results in faster disease progression than can be explained by either alone. “Smoking and obesity significantly interacted to increase the risk of disability…

Severe obesity during childhood and adolescence more than triples the risk of developing multiple sclerosis (MS), and losing weight through early lifestyle changes did not decrease the likelihood of MS, according to a nationwide study in Sweden. Although the overall risk remained low, with 0.13% of people…

Obesity promotes molecular signatures associated with more inflammation and multiple sclerosis (MS) signaling pathways specifically in females, which may explain the link between obesity and a higher risk of MS in women. These are the findings of a new study analyzing data not only from obese and non-obese women…

Obesity in childhood is associated with a more than double the risk of developing multiple sclerosis (MS) in adulthood, although the overall risk is low, according to a new study. “Our study adds to the evidence that obesity in early life increases the risk for a plethora of diseases…

Genetic variants that contribute to a high body mass index (BMI) during childhood are associated with an increased risk of developing multiple sclerosis (MS), a study found. The relationship is likely influenced by the fact that a higher BMI in childhood is linked to obesity in adulthood and a “longer…

Editor’s note: The Multiple Sclerosis News Today news team is providing in-depth and unparalleled coverage of the virtual ACTRIMS Forum 2021, Feb. 25–27. Go here to see all the latest stories from the conference. The fat-related hormone leptin has pro-inflammatory effects on immune cells, new data show, findings that help in better…

Obesity and a higher body mass index (BMI) are associated with both increased multiple sclerosis (MS) risk and harmful autoimmune activity that is induced by leptin, a hormone secreted by fat cells, a study finds. These results indicate that leptin, which helps regulate…

The number of new cases of multiple sclerosis (MS) possibly due to obesity in childhood and adolescence could rise by  14% in the U.S. over the next 15 years, and by 10% in the U.K., a study reported. While the worldwide risk of MS linked to obesity in early life…

Young men, ages 16 to 20, with a higher the body mass index (BMI) are at greater their risk of being diagnosed with multiple sclerosis (MS) later in life, regardless of physical fitness, according to a Swedish study. Risk rose across “the entire BMI range,” its researchers reported,…

Exposure to disease-modifying therapies does not increase multiple sclerosis (MS) patients’ risk of developing a severe form of COVID-19, according to a registry-based study. However, MS patients who are older, obese, or have severe neurological impairments have a greater risk of developing a severe form of the disease. Findings…

Multiple sclerosis (MS) patients who are obese experience faster degeneration in optic nerve tissue than do those of normal weight, an observational study found. Since optic nerve degeneration correlates with greater nerve loss in the brain, measuring changes in this tissue may be a feasible way to determine…

Multiple sclerosis (MS) patients who are obese experience a faster degeneration in their optic nerve tissue than those of normal weight, a study found. Since optic neuropathy correlates with greater nerve cell loss in the brain, tracking changes to the retina may be a feasible way to determine…

What science has told us about how diet might influence a person’s risk of multiple sclerosis and a patient’s disease course was the topic of discussion at a recent MS conference. Ellen Mowry, MD, a researcher and professor of neurology at John Hopkins, also reviewed some of the dietary…

Despite the fact that being obese or overweight may worsen multiple sclerosis (MS) prognosis, people with the neurodegenerative disease are not more likely to adopt weight loss diets, a small study suggests. The study, “Obesity, dieting, and multiple sclerosis,” was published in the journal Multiple Sclerosis and Related…

A common mutation in the fat-mass obesity (FTO) gene is associated with obesity and increased disability in people with multiple sclerosis (MS), according to a Kuwaiti study. The data, which showed no link between this mutation and an increased risk of MS, highlights the need for more studies about…

Obesity may increase the risk for the development and progression of multiple sclerosis (MS) in children and teens, and it may prevent first-line MS therapies from working. Those findings were reported in the study “Association of Obesity With Multiple Sclerosis Risk and Response to First-line Disease…

Obesity, altered lipid (fat) levels, and elevated leptin — an hormone produced by fat cells — may contribute to neuroinflammation, and worse disease severity in people with relapsing-remitting multiple sclerosis (RRMS), research has found. A study with the findings, titled “Obesity worsens central inflammation and disability in multiple…

Multiple sclerosis (MS) can make our bodies experience pain, become weak, and easily fatigue. We can find it difficult just to walk. These challenges can steal our motivation to be active. But without regular activity, we become sedentary, which can increase weakness and fatigue symptoms that cause additional health…

Risk factors often associated with multiple sclerosis (MS), such as genetic background, obesity and smoking, contribute independently to the disease’s variability and may be an early influence on progression, a study reported. The retrospective study, “Multiple sclerosis risk factors contribute to onset heterogeneity,” was published in the journal …

Being overweight is associated with accelerated grey matter volume loss in the brain, a mark of neurodegeneration, in multiple sclerosis (MS) patients, a five-year observational study shows. But vitamin D levels, often suggested as an MS risk factor, do not seem to affect brain volume over time.

A person’s genes influence the development of multiple sclerosis (MS), but so does the environment — both that in which an MS patient lives, and that which a patient creates through diet and other lifestyle choices, researchers said in a Thursday session at the 34th congress of the European…

Discovery of ‘Fiery’ Cell Death Mechanism May Be MS ‘Game-Changer’ Researchers at the University of Alberta have discovered a process that may be responsible for destroying myelin. Better than that, they also think they have a way of limiting that process using a medication. The inhibitor, known…

Young adults at age 20 who are obese and smoke are not only at a higher risk of developing relapsing multiple sclerosis — those who become MS patients after age 20 are also more likely to advance to secondary progressive MS more quickly, researchers in Sweden report. But the link…

A clear association was seen between the substantial pain that multiple sclerosis (MS) patients experience and lifestyle choices that either augment or ease that pain, like smoking habits, exercise, and diet and weight, researchers in Australia report. Common co-morbidities associated with MS, such as depression, anxiety, and fatigue, were also…

A study of nearly 600 children with multiple sclerosis reported that genes linked to low vitamin D levels and obesity contribute to the risk of developing MS in childhood. While the two are also risk factors for adult-onset MS, obesity and low vitamin D have a larger risk impact on children than adults. The…

Obesity in early adolescence poses a risk for multiple sclerosis (MS) regardless of sex, and an earlier age at puberty also contributes to MS onset at younger ages, especially in overweight teenagers, a study reports. These findings were in the study, “Distinct…

Obese children and young adults appear to be at a considerably higher risk of developing multiple sclerosis (MS), according to researchers at the McGill University in Canada and collaborators at the University of Bristol in the U.K., who found a causal relationship between the two. Their study, “…

A systematic review of existing medical literature on multiple sclerosis (MS) could shed light on MS causes and predictors for disease progression, and on lifestyle changes — ranging from vitamin D intake to weight loss — that might reduce a person’s risk. The report, “Factors associated with onset, relapses…

In a new study titled “Adipsin Is Associated with Multiple Sclerosis: A Follow-Up Study of Adipokines,” researchers report a correlation between an adipokine called adipsin and the pathogenesis of multiple sclerosis (MS). The study was published in the Multiple Sclerosis International journal. Obese adolescents…
