Hypertension, also referred to as high blood pressure, is a transitory or sustained elevation of arterial blood pressure that in long term causes end organ damage. The term Essential hypertension is reserved for patients with no definable cause. It constitutes more than 95% of all cases of hypertension.
Classification of Hypertension by Blood pressure (Joint National Committee, 2004)
|Category||Systolic Pressure mmHg||Diastolic Pressure mmHg|
|Stage I (mild)||140-159||90-99|
|Stage II (moderate)||160-179||100-109|
|Stage III (severe)||≥180||≥110|
Synonyms: Primary Hypertension, Essential Hypertension, Idiopathic Hypertension.
Patients with arterial hypertension and no definable cause are said to have essential hypertension.
The term essential hypertension is reserved for 95% of cases in which no evident cause or structural organ defect can be found for the raised BP
A number of environmental factors have been implicated in the development of hypertension including salt intake, obesity, occupation, alcohol intake, family size, and overcrowding.
It includes high blood pressure caused due to other diseases like – kidney disorders, Neurogenic disorders, Hormonal diseases, Coarctation of aorta, intake of certain drugs (E.g oral contraceptives, anabolic steroids, corticosteroids, NSAID’S, Carbenoxolone, Sympathomimetic agents) etc.
Risk factors for Hypertension includes:-
Diabetes mellitus, Obesity, Smoking, excessive alcohol intake, High cholesterol levels, family history.
Normal blood pressure depends on various factors like nervous control on blood vessels, Renin angiotensin system, various hormones like Atrial Natriuretic peptide and Adrenal steroids, kinin system, Endothelium enzymes, Sodium and water balance excretion etc.
Pathological factors which play central role in High Blood Pressure includes:-
In the younger age group, the cardiac output is often elevated, while in older patients increased systemic vascular resistance and increased stiffness of the vasculature play a dominant role.
There are no specific symptoms related to Hypertension. In many cases Hypertension may go undetected until the blood pressure is taken. That’s why it is also called as “Silent killer”.
Effect of long standing Hypertension on Body occurs in various systems. It includes:-
As hypertension is diagnosed basically through sphygmomanometer, its direct reference on ancient texts cannot be possible but there are many references in relation to blood circulation and cardiovascular systems described in ancient Vedas and Samhitas.
The Causative factors of Hypertensioncan be divided into four types i.e., Diet(Ahara), Lifestyle (Vihara), Psychological factors (Manasa) and Genetic (Bija Dosha). These factors lead to aggravation of Mansika Dosha and Vata, Pitta and Kapha.
Aggravated Mansika Doshas (Psychic factors like stress , anxiety) lead to vitiation of Hridaya (Heart and Mind) . The Aggravated Kapha Dosha due to its slimy,cold ,smooth and heavy properties lead to formation of Dhamani uplepa (plaque formation in blood vessels) which results in narrowing of blood vessels. It also causes aggravation of Vata Dosha.
The Aggravated Pitta Dosha lead to disturbed Agni (Metabolism) causingformation of Aam (toxins in blood due to improper digestion). Aam causes malformation of Rasa Dhatu (Blood plasma).
Aggravated Vata Dosha due to its cold and dry properties causes stiffening of blood vessel walls. It can also lead to disturbance in rhythmic movements of heart.
All these aggravated doshas together lead to Hypertension.
The main line of treatment in hypertension is to regulate Vata Dosha of the body along with Pitta and Kapha. Improve Agni (Digestion), which will boost metabolism of the body. Medhya drugs to balance CNS effect on high Blood pressure and Mutrala drugs to decrease the after load of heart.
1. Kwath (Decoction)/Asava/Arishta(Alcoholic preparations) – Dashmool kwath, Parthadyarishta, Saraswatarishta.
2. Rasa Preparations (Herbo mineral preparations) – Mukta Pishti, Akik Pishti, Hridayarnav Rasa, Hridayamruta Rasa, Nagarjunabhra Rasa.
3. Panchkarma – Internal Panchkarma procedures like Virechan, Basti or Raktamokshan and External Panchkarma procedures like Snehana, Swedana, Shirodhara are very effective in treating chronic hypertension.
5. Examples of Drugs which help in relieving anxiety and stress are:-
6. Examples of drugs which through their diuretic action reduce the after load on heart are:-
7. Examples of drugs which have protective functions to heart are:-
8. Medohar drugs:- They help in blood cholesterol levels and thus decrease the blood pressure by decreasing peripheral resistance
1. Control Body weight according to the BMI, Excess fat in the body leads to clogging up of arteries (atherosclerosis) leading to increase in the blood pressure.
2. Restrict salt intake to less than 5 gm/day. Avoid food rich in salt content like chips, fast food, Namkeen, snacks etc.
3. Avoid oily, fatty and spicy diet. Take foods which are high in potassium and low in saturated fat like fruits and vegetables, whole grain meals (DASH diet), low fat dairy products.
4. Drink 6-8 glasses of water daily.
5. Lashun ksheer paak - Take 2 -3 cloves of garlic and boil it in 1 glass of milk and 1 glass of water till half portion remains. Intake of this milk daily controls high level of cholesterol and also helps in decreasing weight and controls high level of blood pressure.
6. Arjun ksheer Paak – Take 5 – 10 gms of Arjuna bark powder and boil it in 1 glass of milk and 1 glass of water till one fourth of the solution remains. Intake of this milk daily provides strengthening to heart muscles and controls blood pressure.
7. Hypertension is an important disorder where yoga therapy is claimed to be effective. Practise yoga asanas like Bhujangasana, Makarasana, Vajrasana and Pranayama (meditation).
