The pressure of the blood against the arteriolar walls while the heart is pumping is called blood pressure. Low blood pressure, or hypotension, is when this pressure is below normal.Blood pressure between the range of 90/60 mmHg to 120/80 mmHg is considered normal for adults. Lower than this is considered hypotension
In the measurement, the upper reading is the systolic blood pressure, and the lower reading is the diastolic blood pressure. Systolic blood pressure, or a systole occurs when the heart is beating while pumping out blood. Diastolic blood pressure, or diastole is the resting state of the heart between beats.Hypotension can be caused by medical states such as pregnancy, heart problems, endocrine problems or dehydration....

It is highly important to prevent and control High Blood Pressure during the adolescent years because people, who suffer from high blood pressure as teenagers, are at a higher risk of cardiovascular problems and blood vessel problems in later years of their life
Regardless of the complex diagnosis, prevention rules are same for teenagers as for adults: Maintaining a healthy body weight by eating healthy and exercising regularly (at least 3 days a week or more, 20 minutes in the least each day). Smoking, alcohol and the use of drugs are major sources of hypertension amongst teenagers. Hence, refrain from smoking, use of drugs and alcohol or limit them by.... More >>
Autonomic failure is a malfunction in the autonomic nervous system. The autonomic nervous system is that part of the brain that regulates the involuntary muscular actions of our body vital for proper functioning. These muscle actions manifest themselves in the digestive system, the heart muscles, the bronchial muscles and so on
The usage of sympathomimetic drugs, or vasopressor agents, such as fludrocortisones, midodrine, somatostatin, erythropoietin can be used to treat autonomic failure. Vasopressor agents are those which are used to simulate the effects of a branch in the autonomic nervous system, known as the sympathetic nervous system.An effect of autonomic failure is orthostatic hypotension, the symptom of which is dizziness....

When a person suffers from lightheadedness or faints without any known reasons, a tilt table test can come in very handy. This test diagnoses heart rate and blood pressure. The test is initiated with a person lying flat on his back on a table. Then to make it seem as if the person stands up the table is tilted upwards. The cardiovascular responses of a person’s body can be checked by using this test.
As a person stands up, blood flows to his legs and thus a lower amount goes to the heart. Naturally this lowers the blood pressure and the body’s autonomic nervous system handles this by increasing the heart rate. However, if this is not done properly the lower blood pressure can cause a person to faint.... More >>
Antihypertensives are a special class of drugs that are used in the treatment of hypertension or high blood pressure. There are various classes of antihypertensives including the most common ones such as diuretics, ACE inhibitors, beta blockers and calcium channel blockers amongst many. The main objectives of these antihypertensive drugs are to prevent important endpoints of hypertension such as heart failures, stroke etc. The different classes of antihypertensives vary widely in effectiveness, side effects and expenses.
Expensive alternatives are not always more effective than a cheaper agent. The most effective drug in terms of combating hypertension has proven to be the thiazide diuretics and is widely regarded as a first line choice of drugs available for high blood pressure. Diuretics assist the kidneys to get rid of the excess amount of water and salt from the blood and tissues from the body.... More >>
All children, including infants, can have high blood pressure. In a child, high blood pressure is defined as having a blood pressure that is higher than 90 percent of the children who are of the same sex, age and height as that particular child. Unlike adults there is no specific range for blood pressure values in children, because their blood pressure changes as they grow. High blood pressure in children who are below ten years of age is usually a symptom of a medical condition – it is what is known as secondary hypertension – high blood pressure caused by underlying diseases.
Studies have shown that children with high blood pressure have a lower cognitive ability than children with normal blood pressure. They are not very good at complicated and goal oriented tasks and have more difficulty at planning. They also have more memory problems than non hypertensive children. If they are hypertensive, and also suffer from obesity, they tend to be more prone to anxiety and depression.... More >>
