Stress Eating – An Overview

It’s a known fact that many of you when stressed tend to eat a lot and the food that is usually consumed is fried sweet or buttery, viz. comfort food. So, why do people tend to eat comfort food when they are in their blues, like for example there is a breakup. The reason is there is a connection between emotions and eating rich food. Many of us would agree of having a whole bowl of ice-cream or a bar of chocolate after a bitter breakup just to soothe ourselves or calm ourselves down.

Stress Eating

When we are stressed, the release of hormones from the body does affect our behavior as well as food choices. The short period of stress like before an exam or a public performance the adrenaline levels go high because the adrenal glands release it thus killing our appetite. The adrenal gland is positioned just above the kidney and is responsible for stimulating hunger. Now when the stress levels are spread over a longer period of time like board examinations lasting for a month or so, the same gland releases cortisol, a hunger and craving stimulating hormone. That is why this hormone by itself is called the stress hormone.

Researchers also believe that Ghrelin, another stress hormone has role to play when it comes to stress eating. And when it comes to food, under stress rarely people want to have healthy food. It’s either high fat or high sugar or both together. Though even as the research is on to find out the reason behind the same, researchers believe that the sugar and fat rich foods send signals to the brain thus leading to a drop in emotional and stress burden. No wonder, these foods are called comfort foods.

Well, so if you are one those who fit under the category of binge eating when under stress a little control could help may be…

Exercise Coupled With Less Calorie Intake Effects Bone Fragility

A recent research on mice has revealed that if exercise is coupled with reduction in calorie intake it tends to make the bones more small, weak and fragile. Researchers also that that if exercise was teamed with adequate calorie diet then it could help in improving bone health in contrast.

The study published in Journal of bone and Mineral research paper. As per Dr Maya Styner, Associate professor of University of north Caroline at Chapel Hill, it came as a surprise to them because the earlier studies carried out on mice revealed that exercise couple with normal or high calorie diet did help improve bone health. So, the report only helps them know that a low calorie diet is not good for bone health if couple with exercise.

Dr Styner also alerted that reduced calorie intake can increase the risk of fracture as well as it negatively affects the bone strength. The study was concentrated upon bone marrow fat. Though still the scientists are not been able to understand how fat works, but they do think that it does affect health in mammals and humans.

Earlier studies as per Dr Styner had revealed that bone marrow fat and bone health were related to each other in a way that when the high calorie intake lead to obesity and further increased the levels of bone marrow fat. Also, when obese as well as mice with normal weight exercised, it lead to a increase in bone density due to the decrease in bone marrow fat.

The objective of the study was to find out how a decrease in calorie intake can affect he bone marrow fat as well as bone health. The research involved two groups of mice. One of the group was fed 30% less calories as compared to the other group. The other group was offered regular calorie diet.

The mice that were on restricted calories also received mineral and vitamin supplements in order to keep the nutrient intake at par with the other normal calorie intake ones. The groups were further split in 6 groups, the sedentary ones and the exercising ones. The results showed that the mice that were kept on a calorie restricted diet seem to not only lost weight but also showed a reduction in bone density and increase in bone marrow fat as well.

The researchers were surprised to see that bones became fragile due to restriction of calories. Though the investigations are not complete yet and further research needs to be done in order to understand the bone marrow functioning, the team did find that reduction in calories lead decrease in bone marrow fat at the same time affecting the quantity and quality of bone.

Hypertrophic Cardiomyopathy – Heart Attack at Young Age

Hypertrophic cardiomyopathy (HCM) is condition that is caused due to abnormal thickening of the myocardium or heart muscle. As a result the heart struggles in pumping blood and ultimately leads to a heart attack. This is not a common heart condition and hence this condition many a times goes unnoticed. Furthermore, some people who suffer from it might or might not experience any symptoms and are able to live routine normal lives. Only a few might experience symptoms like chest pain, issues with the heart’s electrical system , shortness of breath leading to abnormal heart rhythms of dangerous nature.

Heart Attack at Young Age

CAUSES & RISK FACTORS
Thickening of the heart muscle is a condition which is genetic. It has been found that people with this condition do have their heart muscle cells abnormally arranged, thus causing arrhythmia in them.
Well, as the condition is a hereditary condition there is almost over 50% chance that a child may inherit it from the parent or first degree relative like siblings and hence a screening is advisable if anyone in the family is having the condition.

SYMPTOMS
Not everybody suffering from the condition experiences symptoms but the ones who do may experience the following –
1. Chest pain particularly while exercising
2. Palpitations of rapid pounding heart beats
3. Shortness of breath more during exercising
4. Fainting particularly after exertion or exercise
5. Heart murmur detectable by the doctor

COMPLICATIONS
Hypertrophic Cardiomyopathy (HCM) can cause serious heart complications resulting in a life-threatening situation and hence it’s wise to act fast as far as treatment is concerned.
Resulting Conditions
Sudden Death – People suffering from the condition are at a high risk of suffering from a cardiac death due to Ventricular Fibrillation and Ventricular tachycardia, though the chances are extremely rare. It usually affects people at a younger age much below 30 but can occur in all ages.

Atrial Fibrillation – Due to the abnormal structure of the hear cells or thickened muscle it can affect the heart’s electrical system causing irregular heart-beats.

Mitral Valve Problems – Due to the thickened heart muscle, the space for blood flow is limited and hence it could cause the blood to rush or move forcefully into the heart. As a result, the hearts left and right ventricle will not close properly further causing the blood to flow in the reverse direction into the left atrium and worsening the symptoms.

Dilated Cardiomyopathy – This condition can occur in a chunk of people due to the weakening of the heart muscle after it thickens. It can further enlarge the ventricle and decrease the pumping ability.

Heart Failure – Thickening can sometimes lead to making the heart muscle stiff thus avoiding any sort of blood accumulation into it and further as the heart is not able to pump blood, it can cause heart failure.

Prevention
As the cause of the condition primarily is genetic, it can’t be prevented but taking care and carrying out procedures like cardioverter-defibrillator transplant can help you avoid risks like sudden death. Further, the symptoms clearly pinpoint to the fact that when doing strenuous exercise or exertions these symptoms pop up, hence it’s advisable to get your heart checked if someone in the family is having this condition and avoid participating in exercises and sports competitions which can cause exertion to the body.

Leptin Therapy – Cardiovascular Healthcare for People With Too Little Fat

We all know pretty well that too much of fat in body can lead to serious health and cardiovascular problems. But, little do we know that even too little fat can lead to cariovascular issues, as per a recent study. This is a rare condition and is known as Congenital lipodystrophy. It is the polar opposite of high fat condition known as obesity, which we are all aware off and has the ability to damage the heart in the same way as high fat levels.

Fat helps regulate use and storage of fat and is a major leptin producer, considered to be of significant importance in cardiovascular health. If someone has the congenital lipodystrophy condition, then the leptin and fat content is very low. Further, when they consume lipids or fat, there is no way to go and they get stored or piled up rather in the heart, muscle or liver. This is quite unnatural and not good for body organs, thus increasing the risk of diabetes and cardiovascular diseases. There seems to be a visible solution in the pipeline for this condition though and it is called Leptin replacement therapy. Though its effects are largely unknown, doctors are of the opinion that is is a good therapy and works well. It actually restores the endothelial function that get’s impaired when a patient suffers from this condition besides restoring the healthy glucose levels as well.

Now endothelial cells are responsible for production of eNOS,, a dilator, powerful enough to enable the blood vessels to relax. In the condition of lipdystrophy, the NOX1 enzyme expression increases thus producing reactive oxygen species of high damaging levels. The scientists are therefore studying the relationship of endothelial cells and leptin and explore further interactions wherein the want to watch on results of giving too much leptin, could lead to negative results though early on they seem to be positive.

Alternative treatments suggest liposuction of fat deposit removal in addition to exercise and balance diet intake.
