Effect of obesity on brain

 

We know that obesity can lead to many medical problems including diabetes, sleep apnea, depression, heart disease. According to a recent, obesity has been linked to increase the risk of Alzheimer’s disease and stroke. Increase in weight is linked to decline in cognitive performance. Neuroimaging studies of people with morbid obesity suggest that they are at a risk for brain atrophy.

Recent research shows that children with obesity have early brain damage and it is associated with memory problems. Being overweight along with a diet rich in sugar and saturated fats affect the brain and reduces impulse control, which in turn makes it difficult for those children to resist the temptation to eat those same foods that are causing the damage.

Study suggests that obesity reduces the white matter of brain, this affects the ability of a brain to relay signals throughout different parts of the brain. Obesity reduces the brain size in several areas important for attention, memory, and processing speed. As people grow older, they become more vulnerable to brain-related disorders which can make the effect of obesity more important.

A high-fat diet may disrupt brain signals that regulate appetite. A system is designed to control the eating of high-fat and high-sugar foods.  A group of specific proteins were found by Dr. Galli’s team which are responsible for hijacking, they cause changes in brain that lead to a vicious cycle of eating increasing amounts of high-fat and high-sugar foods that likely further cement these changes.

Foods that can help to boost the brain’s function:

• Avocados
• Blueberries
• Broccoli
• Celery
• Dark Chocolate
• Green, Leafy Vegetables
• Salmon
• Walnuts

Obesity and liver health

 

We know that obesity is a risk factor for several noncommunicable diseases, it can lead to diabetes and other metabolic conditions, but there is less awareness that obesity can lead to serious liver disease.

Research shows that with increasing childhood obesity, kids are seen with non-alcoholic fatty liver disease.
Nonalcoholic fatty liver disease occurs when fat accumulates in the liver cells and triggers inflammation, which causes liver damage. It is the most common chronic liver condition seen in children.  It is currently the most common liver disease worldwide. Symptoms can include abdominal pain and slightly enlarged liver.

NAFLD is a part of the metabolic syndrome which can be characterized by being overweight or obese, diabetes, or pre-diabetes, increase in blood lipids such as cholesterol and triglycerides, high blood pressure. Patients can have all the manifestations of the metabolic syndrome or just few.

Following are few of the causes for the development of NAFLD:

• Oxidative stress (imbalance between pro-oxidant and anti-oxidant chemicals that lead to liver cell damage)
• Production and release of toxic inflammatory proteins (cytokines) by the patient’s own inflammatory cells, liver cells, or fat cells
• Liver cell necrosis or death, called apoptosis
• Adipose tissue (fat tissue) inflammation and infiltration by white blood cells
• Gut microbiota (intestinal bacteria) which may play a role in liver inflammation

Weight gain after surgery: Causes and prevention

Weight gain is the most common complication which can arise after surgery. Following are the medical conditions that can lead to weight gain post-surgery.

• Pregnancy: About 80% of women suffer from significant weight gain after pregnancy, where the delivery occurs with the help of a C-Section.
• Kidney problems
• Heart problems
• Thyroid issues
• Adrenal issues
• New medications

The problems which lead to weight gain after surgery:

Fluid Retention: The major cause for weight gain after surgery is the fluid retention. Water is retained in the interstitial space in your body. This leads to weight gain and causes a bloated look. Fluid retention can take place in few parts of the body or the overall body; for example, swollen feet and hands.

Trauma: The body tissues undergo trauma during surgery. This causes inflammation which can lead to fluid retention. The chances of fluid retention are higher if the surgery is due to any accident.

Stress: Hormonal imbalances occur in the body due to stress. This is responsible for excessive fluid retention. Surgery related stress results in high levels of ADH, which makes the kidneys to store the body water. This can also increase weight gain.

Stagnation: Patients are most likely to do very little work after surgery. This leads to weight gain. Patients are encouraged to do some exercises wards off excess weight and also helps to fight post-surgery depression.

Comfort Food: This is the main reason for weight gain after surgery. The cravings that occur post-surgery are the reason for getting the extra calories.

Precautions

• If a patient gains weight rapidly, they must seek medical attention. It can take a week to get back to the normal appetite after the surgery. However, it is crucial not to stop eating or worse, to eat unhealthy foods.
• High-calorie food should be replaced with low-calorie food. It should include foods that are high in fiber and water.
• Safe exercising and weightloss options such as yoga, swimming, brisk walk are good precautions to prevent weight gain.
• It is also advisable to get ample sleep and to take some precautions against overstressing immediately after the surgery.
• Avoiding alcohol and smoking is beneficial to health.
• The right health supplements can promote health and help combat negative side effects after surgery.

Impact of obesity on memory

Research has shown that adults who are obese can have problems with memory especially the one dealing with past events. Excess body weight is a reason for the alterations in the function and structure of the brain and its ability to do certain tasks. This study sheds light on better understanding the link between overeating and memory.

It suggests that consuming  2,100 to 6,000 calories per day can double the risk of memory loss among the people who are over the age of 70. BMI can negatively impact functioning of the brain in older adults.

A new study by the epidemiologists of Brown University found that children who are obese in the first two years of their life had lower reasoning skills and memory compared to  the other children at the age of 5-8. The study showed that IQ scores can lower for the children with higher weight.

How does Obesity impact brain memory?

Obesity poses stress on the joints, heart and other organs, it also affects the brain and its abilities. Excess body weight can be associated with the changes in the structure and function of the brain and its ability to perform tasks.

Obesity has been linked with dysfunction of the hippocampus, an area of the brain which is involved in memory, learning, decision making, problem solving and emotions, suggesting that it might also affect memory.  The hippocampus is in charge of the autonomic nervous system. Eating foods high in fat content can promote changes in the hippocampus, this leads to poorer memory. Changes in the hippocampus may increase overeating and thoughts of food, leading more weight in obese people.

Researchers at University of California Los Angeles found that people with obesity have lesser brain mass compared to people with normal weight. Obese people have 8 percent brain tissue lesser and overweight people have 4 percent lesser brain tissue.

Researchers from University of Cambridge Department of Psychology have found that overweight young adults may have poorer episodic memory, the ability to recall past events, than people with normal weight.

Lack of sleep and obesity

 

Research has showed that there is a link between body weight and sleep. People who get too little sleep weigh more than those who get enough sleep. Lack of sleep reduces glucose metabolism, increases blood pressure and affects appetite regulation. Sleep deprivation increases  the energy intake affects overall energy expenditure.

Studies revealed cross-sectional associations between getting sleep lesser than six hours and increased body mass index. Appetite regulation is controlled by the signals of the brain, and it is impacted by sleep restriction. It impacts secretion of the signal hormones ghrelin, which increases appetite and leptin, which promotes hunger. This can lead to increased food intake without the compensating energy expenditure.

One  explanation of why sleep deprivation makes a person overweight is because of the stimulation of brain. When the individuals are awake for longer time, they will be exposed to food stimuli. With food being available easily and advertisements everywhere, it is hard to avoid food exposure at night. If a person is tired all the time, they are less likely to be physically active.

To decrease calorie intake and maintain a healthy weight, a person should get seven to nine hours of sleep each night!!
