World Hypertension Day is celebrated annually since 2005 to publicize the message of maintenance of normal blood pressure amongst the general public. The theme for World hypertension day 2017 is KNOW YOUR NUMBERS!
According to the statistics, it is noted that around 3 out of ten people are suffering from hypertension worldwide. Hypertension is a condition called high blood pressure during which the arterial blood pressure raises to high level from the normal level (120/80 mmHg). It is a medical condition called a silent killer as it does not show any clear symptoms however severe hypertension show some symptoms of headaches, sleepiness, palpitation, blurred vision, fatigue, dizziness, confusion, ringing sensation in the ears, breathing difficulty, irregular heartbeat which may lead to even coma.
It is divided into two types (primary or essential hypertension and secondary hypertension) on the basis of its causative factors. The primary hypertension is more common, though its causes are unknown. Causes of secondary hypertension include: kidney damage, adrenal gland over-activity, sleep apnea syndrome, tumors, recreational drugs, thyroid gland dysfunction, pregnancy-related conditions, over or wrong medications, alcoholic drinks, diet etc.
FACTS ABOUT HYPERTENSION
Hypertension is defined as blood pressure higher than normal 120mmHg over 80mmHg considering age, e.t.c.
A diagnosis of hypertension may be made when one or both readings are high: systolic (the pressure as the heart pumps blood around the body), given first; or diastolic (pressure as the heart relaxes and refills with blood), given second.
Modern lifestyle factors are responsible for a growing burden of hypertension: physical inactivity, salt-rich diets with processed and fatty foods, and alcohol and tobacco use.
High blood pressure can also be secondary to other conditions – kidney disease, for example – and can be associated with some medications.
Hypertension itself does not cause symptoms but in the long-term leads to complications caused by narrowing of blood vessels. Diagnosis of high blood pressure is done over a number of visits using a sphygmomanometer, which involves applying an inflatable cuff to the upper arm. Lifestyle measures are used first to treat high blood pressure, including salt restriction and other dietary changes, moderation of alcohol, and stress reduction. One or more drugs from a number of different classes may be used for treatment.
