Over the last few decades, the word cholesterol has assumed a different connotation. It has come to be known as a silent killer that spells doom for health. However, what we need to realize is that a certain amount of cholesterol is essential for the proper functioning of the body. The liver produces about 85% of the cholesterol that is required by the body normally. The ever changing food habits have introduced a lot of processed foods that are loaded with saturated fats. Along with this, reduced physical activity has led to accumulation of cholesterol in the blood.

The types of cholesterol are based on the density and we have 2 types of density that is Low Density Lipoprotein (LDL) and High Density Lipoprotein (HDL). LDL is more dangerous than HDL, called as bad and good cholesterol respectively. In addition, the triglycerides and lipoprotein are also critical indicators of overall cholesterol levels. Depending on a person's age, height and weight, normal levels are derived for each of these four.

Because of their density of the cholesterol molecules, as they are circulating in the blood stream, they tend to get sluggish and settle down along the walls of the blood vessels, referred to as plaque. This plaque attracts more and more cholesterol from the blood and the layer gets gradually thicker. This reduces the thickness of the blood vessels and in severe cases even completely blocks blood flow to important organs like the brain and heart, leading to severe conditions like stroke and heart attack respectively.

However, it is not always that all cholesterol is bad. It is one of the essential things for the proper body functions with the main functions listed below.

1. Each cell in the body requires it to form the cell membrane, the protective layer around the cells
2. Synthesis of vitamin D is done with the help of cholesterol, which is very essential for skin health
3. It also helps in hormone formation. In addition to steroids, other hormones like testosterone, estrogen, cortisol require cholesterol as a main ingredient
4. Formation of neurotransmitters and overall nerve function requires cholesterol. This ensures optimal neurological functioning.

So, as noted above, there are, both good and bad aspects to cholesterol. It is not all that dangerous a thing that it is made out to be. The trick is to maintain a good level of cholesterol so that the body's requirements are met, and at the same time, the harmful effects are kept at bay. Some important parameters to manage, include the percentage of bad cholesterol in the blood and the ratio of triglycerides to HDL in the blood. These are considered fair indicators of heart health and if need be, lifestyle changes and/or medications can be undertaken to manage overall health and reduce risk of heart disease and stroke.

Cholesterol: Good and Bad of It

There are different types of heart problems like coronary artery disease, congenital heart failure and cardiomyopathy, but their warning signs are the same i.e. shortness of breath. This is the reason why shortness of breath should never be taken lightly and should always be investigated for heart diseases.

Why does shortness of breath happen?
You may not be able to get in enough air while experiencing shortness of breath. Known medically as dyspnea, shortness of breath is often described as an intense tightening in the chest and a feeling of suffocation. This is one of the most frightening conditions experienced by a patient. You can experience dyspnea without any serious medical problems in these conditions

After strenuous exercise
In extreme temperatures
Due to obesity and
In high altitudes
But if you are not in any of these conditions, then shortness of breath is a sign of a serious medical problem usually involving your heart or lungs. These two vital organs transport oxygen to the rest of your body and remove carbon dioxide; hence problems with either of these organs can affect your breathing. Shortness of breath that comes on suddenly called acute, can be due to other causes too like:

Asthma
Excess fluid around the heart
Low BP
Heart failure
Blood clot in an artery in the lung
Collapsed lung
Pneumonia
If you have had shortness of breath that has lasted for weeks, then we call it chronic and its causes can be various diseases of the heart apart from asthma and COPD. There is no doubt that your heart may be in trouble, if you have chronic shortness of breath. You may be suffering from these heart conditions:

Cardiomyopathy or problems with the heart muscle cause symptoms like shortness of breath after physical exertion as well as fatigue, and swelling of legs and abdomen. Patients suffering from cardiomyopathy are at risk of sudden death due to cardiac arrest.
Heart arrhythmias is also called irregular heartbeat, and can cause slow or fast heartbeats. These also have symptoms like shortness of breath. Arrhythmias can cause strokes, heart failure and cardiac arrest.
Heart failure occurs when the heart is unable to pump blood efficiently to meet the needs of the body. This is a potentially fatal condition. One of the most common symptom is shortness of breath with exercise and while lying down. Fatigue is another common symptom.
Pericarditis or swelling of membranes around the heart is also characterised by shortness of breath.
Treatment of breathlessness can start after you are referred to a heart specialist for further tests to confirm the likely cause.

Shortness in Breath - Can Your Heart Be In Danger?

How many of us have heard about Extracorporeal Membrane Oxygenation (ECMO) before Tamil Nadu, Chief Minister late J Jayalalithaa was put on it for recovery? Hardly a handful. Patients who are placed on the device have 50-50 chance of survival and while it could not help the late Chief Minister, her condition put a spotlight on ECMO.

What is ECMO?
ECMO is a life support device that is put in place when a patient's heart and lungs stop functioning completely post a cardiac arrest. When the patient does not respond to Cardio Pulmonary Resuscitation (CPR), the patient is put on ECMO.

Function of ECMO
The core function of the device is to separate carbon dioxide from the blood and add oxygen into it. It takes the load off from heart and lungs, providing critical time to the body organs for its treatment and recovery.
Patients are only put on ECMO, if there is a chance that the condition can be reversed.

How does ECMO work?
The device drains blood from a vein, which is attached to an oxygenator machine. The machine then removes carbon dioxide from the blood and adds oxygen to it. Depending upon the condition of the patient, the warm blood is either pumped into the body with the help of the machine or is transferred back into the body through an artery.

How long a patient can be on ECMO?
After seven days of being put on ECMO,there are chances of patient getting an infection.
In case the patient contracts an infection, it is recommended to take the patient off ECMO support.

High blood pressure can lead to hypertension, which is known to cause a variety of debilitating side effects or symptoms in the life of the patient. It can also lead to a number of related ailments which can affect the various organs of the body. The eyes are one of the organs that are most susceptible to this kind of spike in the body s blood pressure. Let us learn more about the connection between the two.

Retina: When high blood pressure goes untreated for a prolonged period, it can easily start to affect the blood vessels that can be found in the retina. The retina is the third or the inner most layer of the eye which is sensitive towards light and usually helps in refraction. This is where the light reaches so that one can focus clearly on an image. When the blood pressure of the patient stays high for a prolonged basis, there is significant pressure on the blood vessels in this part of the eye which can lead to an eye disease known as hypertensive retinopathy.

Symptoms: Symptoms of this eye disease include lack of clarity and focus when the eye comes to rest on an object, as well as headaches and other vision problems that typically spring from eye strain that one will go through while trying to focus even harder. It may be seen that the symptoms do not appear in the very early stages of this disease.

Diagnosis: The diagnosis of the condition is usually done by an ophthalmologist who will use an ophthalmoscope in order to project light towards the specific part of the eye so that the back of the eyeballs can be examined. The signs that the doctor will look for during the examination include narrowing of the blood vessels in this part of the eye, inflammation of the macula which is the central portion of the retina, and bleeding in the back of the eye. Also, the doctor will check for spots in the retina with the help of cotton swabs and exudates.

Treatment: The best and only way of treating this condition is by keeping one s blood pressure in control with the help of medication prescribed by the doctor.

Prevention: There are many ways of preventing the onset of this disease, including losing weight so that there is less pressure on the body. Also, one must stick to a healthy diet and exercise regularly after taking recommendations on the appropriate exercises from the doctor. Additionally, it is also important to see a doctor on a regular basis so that there is constant monitoring and regulation of the medicines and the blood pressure.

Blood Pressure - How it Affects Your Eye Sight?

Coronary artery disease is characterized by accumulation of plaque in the coronary artery that chokes blood supply to the heart. This plaque buildup usually starts with cholesterol accumulation and gradually other particles such as calcium and lipoproteins get deposited as well. Over time, the plaque accumulates, making the blood vessels narrow and choking the supply of blood. In some cases, if the plaque ruptures, it may lead to formation of blood clots resulting in stroke.

The symptoms of coronary artery disease are:

1. Breathing difficulties: This disorder may lead to shortness of breath as the blood pumping mechanism of the heart is impaired; this usually results in fatigue and exertion. It is advised to avoid advanced cardio exercises such as the high intensity interval training.

2. Chest pain: Stress related activities may cause intense pressure or tightness in your chest, resulting in pain in the middle or left portion of your chest. If you discontinue the activity, the pain would usually subside. In some cases, you may feel the pain in the arm and the neck.

3. Heart attack: If the level of plaque accumulation is excessive, then it may result in a heart attack. It is characterized by breathing difficulties, pain, tightness in the chest and sweating. You may also experience pain in the neck and the jaw.

The causes of coronary artery disease are:
1. Smoking and alcohol consumption
2. Leading a sedentary lifestyle ups the risk of coronary artery disease
3. Hypertension
4. High cholesterol levels in the body
5. Blood sugar problems

Treatment
1. Get your blood pressure under control: If you suffer from high blood pressure, then it is recommended to get it under control to prevent coronary artery disease.
2. Quit smoking: If you are a habitual smoker, then it is time to nip the habit in the bud. Smoking is known to constrict blood vessels as it is a vasoconstrictor.
3. Eat healthy: Eat a well balanced diet consisting of vegetables and fruits so that your body receives the essential nutrients to function well.
4. Beat stress: You need to control your stress levels through exercise or meditation. Take time off work and do activities that make you happy.

5 natural ways to control your blood pressure

Blood pressure rises with each heartbeat and falls as your heart relaxes. The normal blood pressure should be less than 120/80 mm hg. An increase or decrease on either end can cause various problems.

Here are some of the natural ways to control your blood pressure.

1. Having a diet low in sodium

In the event of a high blood pressure, curtail the consumption of foods that are rich in sodium. However, research reveals that sometimes it is not just enough to cut down on sodium in your diet. A person suffering from high bp should consume foods rich in minerals like calcium, magnesium and potassium as well to keep his/her bp in check.

2. Drink plenty of water and curtail the consumption of alcohol

In case a person suffers from low blood pressure, it is advisable to drink plenty of water as low blood pressure is usually accompanied by bouts of dehydration, and consumption of water can help increase your blood pressure. Also, health drinks, which are rich in electrolytes, help your raise blood pressure. But one should avoid drinks that are high in sugar, and abating your alcohol consumption also helps to quite an extent.

3. Burn extra calories and exercise regularly

Blood pressure usually increases with weight. Being overweight can lead to sleep apnea, which is marked by disruptive breathing while you sleep, which in turn condition can lead to increased blood pressure. Studies have found that weight loss is one of the most effective ways to control high bp. Regular physical activity is also advised to maintain a stable blood pressure.

4. Avoid long, hot showers

The hot water in showers and spas can expand your blood vessels, which can often lead to a drop in blood pressure. A common sign of this would be dizziness and fainting while taking a bath. Therefore, for people suffering from this condition, using warm water rather than hot water is advisable.

5. Completely avoid stress

One of the contributing factors of high blood pressure is chronic stress. Stress tends to affect blood pressure in indirect ways. Many react to stress by overeating, consumption of alcohol and smoking, all of which can increase your blood pressure. Try to know what triggers your stress and take steps to avoid it.
