Difference Between Hypertension and Hypotension?

Hypertension is the medical term for high blood pressure, while hypotension is the word for low blood pressure. When it comes to medical issues like hypertension and hypotension, it is important to know that the two may be opposite, but they are both dangerous. Most people find out whether they have normal or abnormal blood pressure at regular doctor appointments, as both hypertension and hypotension are considered serious enough for most doctors to regularly check blood pressure. Unfortunately, some only find out after the issue has already caused either symptoms that are impossible to ignore, or serious medical conditions that are related to hypertension and hypotension.


Many people suffer from hypertension, as their resting blood pressure is consistently higher than it should be. Unfortunately, most people do not find out about their hypertension for years because there are few definitive symptoms associated with it, especially in mild cases. Symptoms of accelerated hypertension include vision issues, fatigue, headaches, and vomiting, though only a minority of patients are diagnosed with this type, or experience any of these signs. Instead, hypertension can go undetected for years, often leading to stroke, heart failure, aneurism, or kidney failure. Even without these complications, having consistently high blood pressure can lead to shorter life expectancy.


On the other hand, hypotension carries lots of symptoms with it, which means that patients suffering from low blood pressure seem more likely to get treatment than those dealing with high blood pressure. Patients with hypotension usually complain of dizziness, headaches, chest pains, difficulty breathing, nausea, and a heart that beats rapidly. Though having symptoms may mean that patients with hypotension are likely to seek medical treatment, the unfortunate side is that most of the symptoms are caused by underlying issues rather than just low blood pressure. These include hemorrhage, anemia, congestive heart failure, sepsis, and other troublesome medical issues.

In most cases, both hypertension and hypotension can be treated when recognized, or even prevented in some cases. Hypertension can often be eliminated with weight loss, the addition of an exercise routine, and a low sodium diet. Medicine available for it includes ACE inhibitors, beta blockers, and diuretics, to name a few. Hypotension usually requires the doctor to address the underlying issue, but the use of steroids, certain medications, and control of the blood sugar can all help. While both hypertension and hypotension can become quite serious and should never be ignored, each issue is typically treatable when caught early.


Effects


If blood pressure is too high, it can rupture a blood vessel and cause bleeding in the brain, known as hemorrhagic stroke, or other complications. If blood pressure is too low, the blood may be unable to supply enough oxygen and nutrients to the cells and efficiently remove waste from the cells.

Natural Variations

Blood pressure varies naturally with age. Infants and children usually have lower blood pressure than adults. Activity also affects blood pressure, which is higher when a person is active and lower at rest. Time of day also affects blood pressure, which is highest in the morning and lowest at night, during sleep.

Normal Values


Measurement of blood pressure is usually given as two numbers. It's presented in the form of a fraction, with systolic pressure /(over) diastolic pressure, such as 125/85 (or 125 over 85). A reading below 120/80 is considered normal, below 95/60 is considered low blood pressure and higher than 140/90 is considered high blood pressure, or hypertension.

Risk Factors


Risk factors for developing high blood pressure include stress, smoking, high cholesterol, lack of exercise and being overweight. Low blood pressure can be caused by decreased cardiac output, decreased volume of blood or increased capacity of blood vessels. Each of these conditions has several possible causes, including abnormal heart rhythm, heart muscle damage, heart valve disorders, pulmonary embolism, excessive bleeding or sweating, septic shock, excessive urination, exposure to heat, diarrhea or certain drug side effects.

Prognosis


Untreated high blood pressure increases a person's risk of developing heart disease, kidney failure and stroke at an early age. High blood pressure is the most important controllable risk factor for stroke and one of the three major ones for heart attack. On the contrary, healthy people with low normal blood pressure at rest tend to live longer, according to Dr. Robert Berkow, author of "Merck Manual of Medical Information."

Stress is the main reason for high and low pressure. This is what I get into the post.
