High blood pressure

Description of High blood pressure

Definition of Hypertension 
High blood pressure is also known as hypertension. It occurs as a result of the blood flowing through your blood vessels, being consistently too high.
Causes and Risk Factors for Hypertension 
There are two types of hypertension namely, essential hypertension (primary hypertension) and secondary hypertension.
Essential hypertension is a condition in which the exact cause of hypertension is not known. It has a multifactorial etiology namely:
1. Genetic factors: Hypertension runs in families and children of hypertensive parents tend to have increased blood pressure.
2. Factors present at birth: Low birthweight is associated with subsequent high blood pressure.
Secondary hypertension is caused due to a specific and potentially treatable cause like:
1. Kidney disorders
2. Endocrine causes: Conn’s syndrome, adrenal hyperplasia, pheochromocytoma, Cushing’s syndrome, and acromegaly.
3. Congenital cardiovascular defects
4. Drugs: Oral contraceptives, NSAIDs, steroids, antihypertensive drugs, and illegal drugs like cocaine and amphetamines.

Some common factors that increase your chances of developing high blood pressure are:
1. Older age: Adults over the age of 35 are at a higher risk for having high blood pressure.
2. Family history: If either your parents or grandparents had high blood pressure, there is an increased chance of developing high blood pressure.
3. Overweight/obesity: If you are obese or overweight there is increased risk of suffering from hypertension.
4. Diet: If your diet regularly consists of foods that are high in sugar or fat content and low in minerals and fibers then you are putting your body at increased risk of developing hypertension. Increased sodium intake (which comes from salt) increases the risk of hypertension.
5. Lack of exercise: Reduced physical activity increases your weight which in turn increases your risk of hypertension.
6. Drinking too much alcohol regularly: Drinking more than two alcoholic drinks per day, increases your chance of having high blood pressure.
Signs and Symptoms of Hypertension
Most people with hypertension are asymptomatic, even if their blood pressure is very high. Some people may present with headaches, nosebleeds, or palpitations. Hence, generally it is an accidental finding during a routine checkup.
You must get your blood pressure checked after age of 35 especially if you have other risk factors. Owing to the fluctuating nature of high blood pressure, you must get it measured at different time of the day or after specific triggers like exercise, exertion, etc. It is very important to take two to three blood pressure readings during each visit for about three to four appointments so it can be made sure that patient is actually suffering from hypertension. Other investigations like complete blood count, kidney function tests, serum lipid profile, and an electrocardiogram (ECG) may be required to rule out secondary hypertension.
Treatment of Hypertension 
There are many drugs like beta-blockers, alpha-blockers, ACE inhibitors, diuretics, etc. that help in controlling high blood pressure. Depending on the cause of hypertension, the severity of the condition, and presence or absence of other concomitant diseases, your physician will select medicine that is best for treating your hypertension.
Complications and When Should You See a Doctor
After considering the risk factors mentioned above, if you suspect your pressure could be on higher side, you should visit a doctor to get it checked regularly for few days so a diagnosis can be made and accordingly, treatment is decided for you. 

The complications of untreated hypertension include:
a) Chronic kidney failure
b) Heart disease like heart attack, and a risk of stroke
c) Sudden death due to internal bleeding in the brain is also possible. 

Frequently Asked Questions about High blood pressure

With no obvious symptoms, it is possible to have high blood pressure for years before developing any visible symptoms and becoming aware of it. Common signs of high blood pressure are headache, sweating, nervousness, dizziness, shortness of breath and nosebleeds. Signs like these are missed most of the time and misunderstood for a stress headache/migraine, or ‘ weakness’ or a result of stress. Triggers for high blood pressure, among others, are family history, age and weight, lack of exercise, excessive alcohol, stress, and excess salt intake.
Having a history of high blood pressure in the family increases your chances of developing this disease. i.e. parents, grandparents and siblings. Though, your spouse’s family history of high blood pressure does NOT increase the risk for it.
Being overweight at any age increases the chances of developing high blood pressure. However, if you are above 40 and overweight, then chances are extremely high that you have high blood pressure.
A sedentary lifestyle, wherein you end up not engaging yourself in physical activities, along with stress increases the odds that you may have high blood pressure. Similarly, regular and excessive consumption of alcohol, such as 1-2 glasses or more every day, puts you at a greater risk of developing high blood pressure.

Increasing dietary potassium shall significantly help to lower blood pressure levels, study reveals. In a recent study, conducted by University of Southern California (Health Sciences), experts studied the association of dietary potassium with low blood pressure levels. Researchers studied and reviewed the association of blood pressure with dietary sodium and sodium – potassium ratio in the body. The study reviewed several studies that demonstrated the link between the two. It was found that higher dietary potassium (estimated from urinary excretion or dietary recall) was associated with lower blood pressure levels, regardless of sodium intake. It was also observed that when the dietary potassium levels are high, more salt and water is excreted by the kidneys, which also increases potassium excretion. As per the study, eating potassium-rich foods such as sweet potatoes, avocados, spinach, beans, bananas, and coffee were found to lower the blood pressure levels.

As per Ayurveda, high blood pressure or hypertension involves a disruption of balance in the blood (doshas) primarily by vata dosha with pitta and kapha being the secondary doshas. This leads to changes in various organs causing the disease.
According to Ayurveda, hypertension can be attributed to 2 types of causes. 1. Diet-related Causes (Aharaj-nidana): These include excessive salt intake (atilavana), alcohol intake (atimadyapana), and meat consumption (mansa-sewan). 2. Lifestyle-related Causes (Viharaj-nidana): These causes chiefly include staying awake at night (ratrijagarana), sleeping during the day (divasvapna), holding on to natural urges like urination (vegavidharana), sedentary lifestyle (avyayama), overexertion (ativyayam), stress and anxiety (manashetu).

Findings from the study suggested that people who drank sugary drinks more often were at 12% increased risk of blood pressure compared to those who drank none. The drinks broadly included sodas, fruit punch, lemonade and sports or energy drinks. It was also observed that people who regularly consumed these sugary drinks consumed less healthy food through out the day and therefore had severe health issues.

The top number (systolic blood pressure) measures pressure in blood vessels when the heart beats (when heart contracts).The bottom number (Diastolic blood pressure) measures pressure in blood vessels in between heartbeats (when heart is resting). Normal BP means values less than 120/80 mm Hg (120 systolic AND 80 diastolic) for adults aged 20 or over. High Blood Pressure (Hypertension) is when blood pressure is constantly at or above 140/90.
