DIET AFFECTS OUR CIRCULATORY SYSTEM

Our diet and lifestyle affects our circulatory system and causes many diseases such as heart attack, blood pressure, diabetes , asthma etc.

Heart attack ((Myocardial infarction)

The heart is made up of muscle cells . These cells just like other cells in the body must receive oxygen and food through the circulatory system. The blood vessels which supply oxygen  and food to the heart are called coronary arteries.

A hard substance called plaque can build up in the walls of coronary arteries. This plaque is made of fat and other cells. The coronary arteries may become narrow due to plaque. Sometimes a blood clot forms on the plaque and blocks coronary arteries. Due to this, the blood cannot reach a part of the heart. This part of the heart  begins to die due to lack of oxygen and food. The death of a  part of the heart is called a heart attack myocardial infarction. If too much heart  muscle dies, the heart is unable to pump the blood and the person could die. Heart attack symptoms may include chest pain, shortness of breath, heavy sweating etc., which is a medical emergency. Call 1122 or another ambulance.



TIPS TO AVOID HEART ATTACK

• Take foods high in fiber and low in fat.


• Take regular exercise to increase blood circulation throughout your body.


• Don't smoke. Smoking can increase your blood pressure.

High blood pressure ( hypertension)

High blood pressure is a disorder of the circulatory system. Blood pressure is the amount of force exerted by blood against the walls of the arteries. If the blood pressure of a person remains above the normal value (120/80) , the condition is called high blood pressure or hypertension.

 The increased blood pressure can damage blood vessels and the result may be the failure of

Kidneys and heart. People  with high blood pressure may have the symptoms  such as  headache, fatigue , blurred vision, nosebleeds etc. Foods high in fat, high salt intake, smoking, obesity, diabetes, lack of exercise etc. Raise the risk of high blood pressure.



Smoking can cause heart disease. It has been found that a person who smokes is more likely to have heart problems than someone who does not smoke. A chemical in tobacco smoke causes blood vessels to become narrower. The blood pressure of a smoker may increase. The heart works harder to pump blood through these narrow vessels. Heart patients are also asked not to smoke. whycigrates should not be advertised?

Diabetes:

Diabetes is a disease in which a person has high blood sugar, because his/her body does not produce enough insulin. Insulin is the chemical that is produced in our pancreas insulin helps to decrease blood sugar. Without insulin a person develops diabetes.



Loss of weight, frequent urination, excessive thirst and hunger etc. Are some of the symptoms of diabetes. If the patient does not control the level of blood sugar he/she may be the risk of loss of eyesight and hearing, heart attack, gum disease , kidney disorder etc.

A person can control his/her blood sugar level by taking medicines, eating a proper diet and taking exercise.



Carbohydrates have a big impact on our blood sugar level. Extra fats are not good we need to take these foods carefully, some vegetables and fruits are useful for a diabetic patient.

Asthma:

Asthma is an allergic the c uses the airways of the lungs to swell and narrow. A person with asthma may wheeze ( a whistling sound when he or she breathes). Cough and feel tightness in the chest.

The things that can cause asthma are called allergies. Dust mites, pollen grains and smoke foods may cause asthma are called allergies. Dust mites, pollen grains and some foods may cause asthma.

Symptoms of an asthma attack may be cough, shortness of breath, wheezing, extreme difficulty in breathing, chest pain, sweating and increased pulse rate. A severe asthma attack may lead to death.

 It is not easy to cure asthma, but one can be normal and act even with asthma.

• Try to avoid the allergens of asthma.


• Use plenty of water, it will give you relief.


• On the advice of a doctor, use the medicine or inhaler.

TRANSPLANTATION

Sometimes an organ in the body of a person may stop it working because of a disease or injury. In the past, the failure of a major organ resulted in the death of the patient. But , now scientist has found the solution of this problem.



An organ , transplant replaces a failing organ with the healthy organ. A doctor removes an organ from the healthy person and places it in the patient's body. The patient again lives a normal life after transplantation.



Not all organs can be transplanted.organs mostoftely transplanted area:

The kidney because of diabetes or other kidney problems.

The liver because of serious liver disorders.

The heart because of heart failure.

The pancreas because of diabetes.

The lung because of serious  respiratory disorders.



People who have an organ transplant must take medicines regularly the rest of their lives to stay healthy.



Sometimes artificial organs are also used to restore a function in the body of a person. An artificial organ is a man-made device that replaces a missing natural organ. Artificial legs , arms, bones, arteries, eyes, teeth and ears are common to transplant now a days. The scientist who design and build artificial body parts are called biomedical engineers.
