Obesity and Overweight Linked to Long-Term Health Problems After Traumatic Brain Injury

The frequency of seizures -- a common problem among TBI survivors -- was also related to differences in body weight and health status

While obesity has been known to increase the risk of many cardiometabolic diseases in healthy people, it may pose even greater risk for people living with traumatic brain injury (TBI), a study has found.

The study found that for people with moderate to severe TBI, obesity may be associated with long term chronic disease risks including high blood pressure, heart failure, and diabetes.

In TBI patients, weight gain may occur due to a wide range of factors including medical conditions, medications, cognitive or behavioural changes, physical limitations, and lack of transportation or other resources.

“Being obese or overweight presents a health risk in the years following rehabilitation for TBI,” said lead author Laura E. Dreer from The University of Alabama in the US.

“Achieving and maintaining a healthy diet and engaging in regular physical activity following a TBI are critical goals for recovery,” Dreer added.

In the study, published in Journal of Head Trauma Rehabilitation, 7,287 obese patients with TBI who had undergone inpatient acute rehabilitation, rated themselves as having poorer general health.

The frequency of seizures — a common problem among TBI survivors — was also related to differences in body weight and health status.

“Lifestyle and health behaviours related to weight gain will need to be a component of any proactive approach to managing TBI as a chronic health condition,” Dreer said. (IANS)

Genes Tied to Obesity May Lower Risk of Diabetes

"Meanwhile, some lean or normal weight individuals develop diseases like Type-2 diabetes," Yaghootkar noted

Certain genetic factors may impact our body in intriguingly paradoxical ways. A team of scientists has identified 14 new genetic variations that were linked with higher Body Mass Index (BMI) but have the potential to lower risk of diabetes, lower blood pressure and lower heart disease risk.

According to researchers, it is because the location — around middle or round the liver — where surplus fat is stored could be genetically determined.

This location is more important than the amount when it comes to insulin resistance and risk of diabetes and other conditions.

“There are some genetic factors that increase obesity, but paradoxically reduce metabolic risk. It is to do with where on the body the fat is stored,” said Brunel Alex Blakemore, Professor at the Brunel University London.

The findings revealed that as they gain weight, people who carry these genetic factors store it safely under the skin, and so have less fat in their major organs such as the liver, pancreas and kidneys.

“Directly under the skin is better than around the organs or especially, within the liver,” Blakemore added.

For the study, published in the journal Diabetes, the team examined more than 500,000 people aged between 37 and 73.

They used Magnetic Resonance Imaging (MRI) scans of these people’s waists to match where they stored extra fat with whether they showed signs of Type-2 diabetes, heart attack and risk of stroke.

“There are many overweight or obese individuals who do not carry the expected metabolic disease risks associated with higher BMI,” explained Hanieh Yaghootkar from the University of Exeter in Britain.

“Meanwhile, some lean or normal weight individuals develop diseases like Type-2 diabetes,” Yaghootkar noted. (IANS)
