Hypertension.


Hypertension means an increase in blood pressure.
The heart pumps blood into the blood vessels. this creates some pressure that blood exerts against the walls of the vessels. this pressure is called blood pressure.

Systolic BP

it is the pressure of the blood which it exerts against the walls of vessels at the time when the heart contracts. it the pressure which gives us a bumping feel when we try to feel our pulse at the wrist. the normal value of systolic blood pressure is 120 mm of Hg. this value increases with age. 

Diastolic BP

it the pressure of the blood against the walls of vessels when the heart relaxes or at a time when it is not pumping. it is less than systolic and its normal value is 80 mm of Hg.

Why BP rises.

BP rises in following conditions

1. narrowing of the vessels ( increase resistance)

when vessels become narrow they will cause an increase in BP. 
narrowing can be a result of increased sympathetic stimulation that is in fear, anxiety, atherosclerotic state, or any other problem.

2. increase in blood volume.

increase in blood volume will obviously increase blood pressure.
increase in volume is mainly because of kidney problems, heart failure or endocrine problems.
so we have to treat the cause to treat the BP.


regular exercise and decrease sodium intake, increase potassium intake, eating vegetables, balanced diet, and maintaining normal weight and medications can greatly reduce the risk of hypertension

Causes of high blood pressure and consequences

Now hypertension in the clinical setting is defined as systolic blood pressure greater than 140 or diastolic blood pressure greater than 90, recorded in more than two separate occasions.

Human Parasites, Types of Parasites, and Classification

Parasite: A parasite is a living organism which gets nutrition and protection from another organism where it lives. Parasites enter into the human body through mouth, skin and genitalia. In this article, we will generally discuss the types and classification of parasites. It is important from an academic point of view. Those parasites are harmful, which derives their nutrition and other benefits from the host and host get nothing in return but suffers from some injury. Types of Parasites Ecto-parasite: An ectoparasite lives outside on the surface of the body of the host. Endo-parasite: An endo-parasite lives inside the body of the host, it lives in the blood, tissues, body cavities, digestive tract or other organs. Temporary parasite: A temporary parasite visits its host for a short period of time. Permanent parasite: Permanent parasite lives its whole life in the host. Facultative parasite: A facultative parasite can live both independently and dependently. It lives in the

How to taper off, wean off beta blocker, atenolol, Propranolol, Metoprolol

Beta blockers include, atenolol (Tenormin), propranolol (Inderal ) and metoprolol (Lopressor) and are used to treat high blood pressure, certain cardiac problems, migraine and few other conditions. People usually take atenolol, propranolol or metoprolol for many years as a treatment of high blood pressure or after having an episode of heart attack . Sometimes, it becomes necessary to withdraw these beta blockers due to their potential side effects that trouble the patients or sometimes doctor wants to change the drug and shift the patient to some other anti-hypertensive medicine. No matter whatever the cause is, whenever, a patient who has been using a beta blocker for a long period of time, and he needs to be stopped from further usage of that beta blocker, must not stop taking it. One should taper off the dose of a beta blocker. Now a question arises how to wean off or taper off a beta blocker? The method of tapering off beta blocker varies from individual to individual. Allow you
