High blood pressure - hypertension & cholesterol
High blood pressure or hypertension - to give it the correct medical term - is regarded as the silent killer. It is a disease of the modern age. The fast pace of life and the mental and physical pressures caused by the industrial and metropolitan environments give rise to psychological tensions. Worry and mental tension increases the adrenaline in the blood stream and this, in turn, causes the pressure of the blood to rise.
The blood which circulates through the arteries within the body supplies every cell with nourishment and oxygen. The force exert by the heart as it pumps the blood into the large arteries creates a pressure within them and this is called blood pressure. A certain level of blood pressure is thus essential to keep the blood circulating in the body. But when the pressure becomes too high, it results in hypertension which is caused by spasm or narrowing of the small blood vessels, known as capillaries, throughout the body.
This narrowing puts more stress on the heart to pump blood through the blood vessels. Hence, the pressure of the blood to get through rises in proportion to the pressure on the heart.
The blood pressure is measured with the instrument called sphygmomanometer in millimeters of mercury. The highest pressure reached during each heart beat is called systolic pressure and the lowest between the two beats is known as diastolic pressure. The first gives the pressure of the contraction of the heart as it pushes the blood on its journey through the body and indicates the activity of the heart. The second represents the pressure present in the artery when the heart is relaxed and shows the condition of the blood vessels. The blood pressure level considered normal is 120/70, but may go up to 140 /90 and still be normal. Within this range, the lower the reading, the better. Blood pressure between 140/90 and 160/95 is considered border line area. From 160/96 to 180/114 , it is classed as moderate hypertension, while 180/115 and upward is considered severe. A raised diastolic pressure is considered more serious than the raised systolic pressure as it has a serious long-term effect. The higher the pressure the greater the danger it causes to the wall.
Symptoms
Mild and moderate hypertension may not produce any symptoms for years. The first symptoms may appear in the form of pain toward the back of the head and neck on waking in the morning, which soon disappears. Some of the other usual symptoms of hypertension are dizziness, aches and pains in the arms, shoulder region, leg, back, etc., palpitations, pain in the heart region, frequent urination, nervous tension and fatigue, crossness, emotional upset, tiredness and wakefulness.
A person suffering from high blood pressure cannot do any serious work, feels tired and out of sorts all the time. He may experience difficulty in breathing and suffer from dyspepsia. Hypertension, if not eliminated, may cause heart attacks or strokes or other disability conditions such as detachment of the terina.
Causes
The most important causes of hypertension are stress and a faulty style of living. People who are usually tense suffer from high blood pressure, especially when under stress. If the stress continues for a longperiod, the pressure may become permanently raised and may not become even after removal of the stress. An irregular life style, smoking and an excessive intake of intoxicants, tea, coffee, cola drinks, refined foods, destroy the natural pace of life. The expulsion of waste and poisonous matter from the body is prevented and the arteries and the veins become slack. hardening of the arteries , obesity, diabetes and severe constipation also lead to hypertension. Other causes of high blood pressure are excessive intake of pain killers, common table salt, food allergies and eating a high fat, low fibre diet, processed foods deficient in essential nutrients.
The kidneys play an important role in controlling blood pressure through secretion of rennin, a natural chemical. If increased rennin is secreted by the kidneys, more salts are retained in the body, which leads to an increase in the volume of circulating blood and consequently to an increase in the blood pressure. Repeated infections and inflammation in the kidneys can also give rise to hypertension.
The Cure
The modern medical treatment of high blood pressure is highly unscientific as it brings down the pressure by drugs without making any effort to remove the underlying causes. Drugs may temporarily reduce blood pressure,but they do not cure the condition and are harmful in the ultimate analysis. All drugs against hypertension without exception, are toxic and have distressing side effects. The safest way to cure hypertension is to remove the real cause. The natural way of dealing with it is to eliminate the poisons from the system which cause it. Persons with high blood pressure should always follow a well-balanced routine of proper diet, exercise and rest. Diet is of primary importance. Meat and eggs cause the blood pressure to rise more than any other food. The pressure is lowered and blood clotting diminished by partaking of a higher fruit content, lower protein and non-flesh diet. A natural diet consisting of fresh fruits and vegetables, instead of a traditional diet, is helpful in getting rid of the poisons from the body. A hypertension patient should start the process of healing by living on an exclusive fruit-diet for atleast a week, and take fruits at five-hourly intervals thrice in the day. Oranges, apples, pears, mangoes, guava, pineapples, raspberry, water-melon are the best diet in such cases. Bananas and jack fruit should not be taken. Milk may be taken after a week of ‘fruits only’ diet. The milk should be fresh and should be boiled only once. The patient can be permitted cereals in his food after two weeks.
Vegetables are also good for the patient of hypertension. They should preferably be taken raw. If they are cooked, it should be ensured that their natural juices are not burnt in the process of cooking. Vegetables like cucumber, carrot, tomatoes, onion, radish, cabbage and spinach are best taken in their raw form. They may be cut into small pieces and sprinkled with a little salt and the juice of a lemon added to them so as to make them more palatable.
Garlic is regarded as one of the most effective remedies to lower blood pressure. The pressure and tension are reduced because it has the power to ease the spasms of the small arteries. Garlic also slows the pulse and modifies the heart rhythm besides relieving the symptoms of dizziness, numbness, shortness of breath and the formation of gas within the digestive tract. The average dosage should be two to three capsules a day to make a dent in the blood pressure. Indian gooseberry (amla) is another effective food remedy for high blood pressure. A tablespoonful each of fresh amla juice and honey mixed together should be taken every morning in this condition. Lemon is also regarded as a valuable food to control high blood pressure. It is a rich source of vitamin P which is found both in the juice and peel of the fruit. This vitamin is essential for preventing capillary fragility.
Watermelon is another valuable safeguard against high blood pressure. It was proved in recent experiments that a substance extracted from watermelon seeds has a definite action in dilating the blood vessels, which results in lowering the blood pressure.
Recent studies have revealed an important link between dietary calcium and potassium and hypertension. Researchers have found that people who take potassium-rich diets have a low incidence of hypertension even if they do not control their salt-intake. They have also found that people with hypertension do not seem to get much calcium in the form of dairy products. The two essential nutrients seem to help the body throw off excess sodium and are involved in important functions which control the working of the vascular system. Potassium is found in abundance in fruits and vegetables and calcium in dairy products.
Exercise plays an important role in curing hypertension. Walking is an excellent form of exercise. It helps to relieve tension, builds up the muscles and aids in the circulation of blood. As the blood pressure shows signs of abating, more exercise like bicycling, swimming, jogging should be taken. Yogic asanas such as surya namaskar, makrasana,matsyasana, vajrasana, ardhapadmasana, pavan-muktasana, shavasana and simple pranayama like anuloma-viloma and abdominal breathing are beneficial. All asanas should, however, be discontinued except shavasana if the blood pressure is above 200 milimeters.
Water Treatment
Prolonged neutral bath daily for an hour or so at 90 o to 95 o will be beneficial. Cold compress should be kept on the head during this bath. Other water treatments include hot foot or leg bath for 10 minutes, hot compress over the heart replacing it as bath cools down. Persons suffering from hypertension must ensure at least eight hours of restful sleep, because proper rest is an important aspect of the treatment. Most important of all, the patient must avoid over-straining, worries, tension, anger and haste. He must try to be cheerful and develop a contented mind. The natural treatment may take sometime but it is the safest and best way to get rid of this disease.
High Blood Cholesterol
Cholesterol, a yellowish fatty substance, is one of the essential ingredients of the body. Although it is essential to life, it has a bad reputation, being a major villain in heart disease. Every person with a high blood cholesterol is regarded as a potential candidate for heart attack, a stroke or high blood pressure.
Cholesterol is a building block of the outer membrane of cells. It is the principal ingredient in the digestive juice bile, in the fatty sheaths that insulate nerves and in sex hormones, namely, estrogen and androgen. It performs several functions such as transportation of fat, providing defense mechanism, protecting red blood cells and muscular membrane of the body.
Most of the cholesterol found in the body is produced in the liver. However, about 20 to 30 percent generally comes from the foods we eat. Some cholesterol is also secreted into the intestinal tract in bile and becomes mixed with the dietary cholesterol. The percentage of ingested cholesterol absorbed seemed to average 40 to 50 percent of the intake. The body excretes extra cholesterol from the system through bowels and kidneys.
The amount of cholesterol is measured in milligrams per 100 millimeters of blood. Normal level of cholesterol varies between 150- 250 mg. per 100 ml. Persons with atherosclerosis have uniformly high blood cholesterol usually above 250 mg. per 100 ml.
In blood, cholesterol is bound to certain proteins - lipoproteins which have an affinity for blood fats, known as lipids. There are two main types of lipoproteins : a low density one (LDL) and a high density one (HDL). The low density lipoprotein is the one which is considered harmful and is associated with cholesterol deposits in blood vessels. The higher the ratio of LDL to the total cholesterol, the greater the risk of arterial damage and heart disease. The HDL on the other hand plays a salutary role by helping remove cholesterol from circulation and thereby reduce the risk of heart disease.
Cholesterol has been the subject of extensive study by researchers since 1769, when French chemist, Polutier de La Salle purified the soapy-looking yellowish substance. The results of the most comprehensive research study, commissioned by the National Heart and Lung Institute of the U.S.A. were announced about four years ago. The 10-year study, considered most elaborate and most expensive research project in medical history, indicates that heart disease is directly linked to the level of cholesterol in the blood and that lowering cholesterol significantly reduces the incidence of heart attacks. It has been estimated that for every one per cent reduction in cholesterol, there is a decrease in the risk of heart attack by two per cent.
Causes
Hyperchjolsterolaemia or increase in cholestrol is mainly a digestive problem caused by rich foods such as fried foods, excessive consumption of milk and its products like ghee,butter and cream,white flour, sugar, cakes, pastries, biscuits, cheese, ice cream as well as non-vegetarian foods like meat, fish and eggs. Other causes of increase in cholesterol are irregularity in habits, smoking and drinking alcohol.
Stress has been found to be a major cause of increased level of cholesterol. Adrenaline and cortison are both released in the body under stress. This, in turn, produces a fat metabolising reaction. Adrenal glands of executive type aggressive persons produce more adrenaline than the easy going men. Consequently they suffer six to eight times more heart attacks than the relaxed men.
The Cure
To reduce the risk of heart disease, it is essential to lower the level of LDL and increase the level of HDL. This can be achieved by improving the diet and changing the life style. Diet is the most important factor. As a first step, foods rich in cholesterol and saturated fats, which lead to increase in LDL level, should be reduced to the minimum. Cholesterol -rich foods are eggs, organ meats and most cheese, butter, bacon, beef, whole milk, virtually all foods of animal origin as well as two vegetable oils, namely coconut and palm, are high in saturated fats and these should be replaced by polyunsaturated fats such as corn, safflower, sobayeans and sesame oils which tend to lower the level of LDL. There are monosaturated fats such as olive and peanut oils which have more or less neutral effect on the LDL level.
The American Heart Association recommends that men should restrict themselves to 300 mg. of cholesterol a day and women to 275 mg. It also prescribes that fat should not make up more than 30 per cent of the diet and not more than one third of this should be saturated. The Association, however, urges a somewhat strict regimen for those who already have elevated levels of cholesterol.
The amount of fibre in the diet also influences the cholesterol levels and LDL cholesterol can be lowered by taking diets rich in fibres. The most significant sources of dietary fibre are unprocessed wheat bran, whole cereals such as wheat , rice, barley, rye; legumes such as potato, carrot, beet and turnips; fruits like mango and guava and green vegetables such as cabbage, lady’s finger, lettuce and celery. Oat bran is especially beneficial in lowering LDL cholesterol.
Lecithin, also a fatty food substance and the most abundant of the phospholipids, is highly beneficial in case of increase in cholesterol level. It has the ability to break up cholesterol into small particles which can be easily handled by the system. With sufficient intake of lecithin, cholesterol cannot build up against the walls of the arteries and veins. It also increases the production of bile acids made from cholesterol, thereby reducing its amount in the blood. Egg yolk, vegetable oils, whole grain cereals, soyabeans and unpasteurised milk are rich sources of lecithin. The cells of the body are also capable of synthesizing it as needed, if several of the B vitamins are present.
Diets high in vitamin B6, cholin and inositol supplied by wheat germ, yeast, or B vitamins extracted from bran have been particularly effective in reducing blood cholesterol. Sometimes vitamin E elevates blood lecithin and reduces cholesterol presumably by preventing the essential fatty acids from being destroyed by oxygen.
Persons with high blood cholesterol level should drink at least eight to 10 glasses of water every day as regular drinking of water stimulates the excretory activity of the skin and kidneys. This in turn facilitates elimination of excessive cholesterol from the system. Regularly drinking of coriander (dhania) water also helps lower blood cholesterol as it is a good diuretic and stimulates the kidneys. It is prepared by boiling dry seeds of coriander and straining the decoction after cooling.
Regular exercise also plays an important role in lowering LDL cholesterol and in raising the level of protective HDL. It also promotes circulation and helps maintain the blood flow to every part of the body. Jogging or brisk walking, swimming, bicycling and playing badminton are excellent forms of exercise.
Yogasnas are highly beneficial as they help increase perspiratory activity and stimulate sebaceous glands to effectively secrete accumulated or excess cholesterol from the muscular tissue. Asanas like ardhamatsyaendrasana, shalabhasana, padmasanaand vajrasana are useful in lowering blood cholesterol by increasing systemic activity. Hydrotherapy can be successfully employed in reducing excess cholesterol. Cold hip baths for 10 minutes taken twice every day have proved beneficial. Steam baths are also helpful except in patients suffering from hypertension and other circulatory disorders. Mud packs, applied over the abdomen improve digestion and assimilation. They improve the functioning of the liver and other digestive organs and activate kidneys and the intestines to promote better excretion.
