What is high blood pressure or hypertension?
High blood pressure or hypertension is a constant increase in the force that the blood exerts upon the walls of the arteries. This force increases with stress or physical exertion and comes back to normal when the body is at rest. However, in the case of hypertension, the patient's blood pressure remains high even at rest.
Hypertension can be either primary (essential) or secondary. When there is no specific cause for a person's high blood pressure it is called primary or essential hypertension. Secondary hypertension is the result of another ailment such as a kidney disease or tumors. Approximately, only 5-10 per cent of all cases are secondary.
Uncontrolled hypertension can make you vulnerable to life-threatening strokes, heart attacks and arterial aneurysms (localised, blood-filled dilation or bulging of a blood vessel caused by disease or weakening of the vessel wall).
Speaking about the dangers of hypertension, Dr Pradnya Nagle, a general physician, says, "A sudden blood pressure fluctuation can put pressure on the heart and cause a heart failure. It can even cause a brain haemorrage. Our kidneys cannot sustain high blood pressure for long and can result in a renal failure. Retinal changes or haemorrage in the eye could occur resulting in sudden blindness. High blood pressure could also cause paralytic attacks due to a clot or haemorrage in the blood vessels of the brain."
According to Dr Nagle, blood pressure can fluctuate according to the age, sex and race of a person and also with pregnancy. For an adult below the age of 40, a systolic reading of 120 and diastolic reading of 80 is considered normal. A reading of 140/90 and above is considered high.
What are the symptoms and causes?
Most people who have hypertension don't realise it because the disorder doesn't have any fixed, obvious symptoms, which could prove quite dangerous. So the best thing to do is get your blood pressure checked at regular intervals.
"Regular blood pressure check-ups are a must for those who have a family history of hypertension, " advises Dr Nagle. "One should also screen for lipid levels, blood sugar and opt for a renal profile at least once a year."
There are, however, some signs that indicate that you might be suffering from acute hypertension. If you exhibit one or more of the following symptoms, you should get your blood pressure checked immediately.
- Persistent headaches
- Fatigue, drowsiness or confusion
- Palpitations or chest pain
- Bleeding of the nose or blood in the urine
- Numbness in the hands or feet
- Vision problems
- Ringing in the ears
- Difficulty in breathing
- Dizziness
Hypertension and urban youth
There is an alarming increase in the occurrence of hypertension among the urban youth. Apart from heredity, the other culprit is the unruly and sedentary lifestyle of the youth.
Unlike in the past, most young people today climb the social ladder quite fast. They hold positions of responsibility, which puts great pressure on them to perform at their best at all times.
There is no time to maintain a healthy diet, take up constructive physical activity or relax. The fast food or the preserved food culture, irregular meals, late night partying, binge drinking, heavy smoking, lack of sleep and almost no proper physical exercise are instrumental in causing high blood pressure.
How do you treat hypertension?
Acute hypertension needs immediate and expert medical attention; there are no over-the-counter drugs to treat it. But for those who are facing the threat of developing hypertension, here are a few lifestyle changes you could make:
- Invest in a home blood pressure kit. This will help you monitor your blood pressure at regular intervals.
- For those who are obese, it's time to get your weight under control. A few extra kilos are enough to send your blood pressure shooting up.
- If you live a sedentary lifestyle and have no time for the gym, take to walking. Thirty minutes of brisk walking or an extra 4,000 to 5,000 steps everyday can go a long way in keeping your weight, blood pressure and blood sugar under control.
- Aerobics or yoga is another way to get some exercise.
- Limit your salt intake. Develop a low-fat, low-salt food schedule and stick to it. If you are a non-vegetarian, limit your meat intake. And if your blood pressure is soaring, cut out seafood too.
- Discard the junk and preserved food habits; eat healthy. Include a lot of veggies and flaxseed (known as alsi in Hindi, the Omega 3 acid contained in flaxseed is good for the heart) in your diet.
- Get a good night's sleep. Uninterrupted sleep helps your body recover from the day's activity.
- Learn to relax. Take up a hobby or a sport, read a book, listen to soothing music or watch a movie; in short, do something that helps you unwind.
- Meditate. It is a great stress relieving technique and the easiest way to calm down.
- If you are a die-hard smoker, try to cut down and gradually give it up.
- If you have been prescribed a diuretic or an anti-hypertensive drug, take it consistently.
