Hypertension is a common disorder. It occurs when the systolic arterial pressure consistently measures 140 mm Hg or higher, or when the diastolic arterial pressure reaches 90 mm Hg or higher, or both. There are two classifications of hypertension: essential (or primary) hypertension and secondary hypertension. One factor associated with primary hypertension is increased levels of serum sodium (hypernatremia). This leads to higher blood volume and subsequently raises blood pressure. Primary hypertension can also be caused by changes in other body chemicals. Stress can cause some individuals to experience an increased release of catecholamines such as epinephrine and norepinephrine, which contributes to elevated blood pressure levels.
Hypertension, or high blood pressure, can be caused by various factors. One of these is the lack of natriuretic factor, a hormone produced by the heart. The absence of this hormone leads to const
...ant vasoconstriction in the arteries, resulting in increased blood pressure. Other contributors to hypertension include adrenal tumors, acute pain or stress, alcohol withdrawal, amphetamines, birth control pills, cardiovascular disease, Cushing's disease, genetic factors, hyperthyroidism, and kidney failure. Regardless of whether it is primary or secondary hypertension (caused by an underlying condition), both types result in similar organ damage and complications. High blood pressure strains the heart and causes enlargement while also accelerating atherosclerosis which leads to other severe complications.
The different organs of the body, such as the eyes, heart, brain, and kidneys, can experience damage. High blood pressure has the potential to cause ruptured blood vessels and serious consequences. Retina hemorrhaging in small arteries can lead to blindness, while brain hemorrhaging can result in cerebrovascular problems. Reduced circulation to the kidney
can cause renal failure. Hypertension is commonly referred to as "the silent killer" because it often develops slowly without noticeable symptoms. In some cases, a major complication may be the first indication of hypertension. Minor symptoms include consistently high blood pressure readings of 140/90 or higher, headaches, flushed face, pulsing sensation in the head, dizziness, fatigue, insomnia, and nervousness. The most evident sign during a physical examination is a sustained elevation in one or both blood pressure measurements.
The pulse may be strong due to vigorous ventricular contraction. Individuals with high blood pressure might experience excessive weight and swelling in the extremities. Examining the eyes can help detect changes in blood vessels, bleeding in the retina, or a bulging optic disk.
Consistently monitoring blood pressure levels is crucial for diagnosing hypertension. It is recommended to do so at different times and on different days for accurate results. Various methods, including a physical examination, comprehensive medical history evaluation, laboratory blood work (such as kidney profile, thyroid profile, and adrenal gland function), urinalysis, electrocardiogram, and chest x-ray can be used by a medical doctor to evaluate hypertension.
There is currently no cure for hypertension that is not secondary to another disease or condition.
To effectively control the effects of hypertension, there are various approaches available. The management of hypertension in its early stages relies on the level of pressure elevation. Nonpharmacologic therapy, including rest, stress reduction, counseling, weight loss, sodium reduction in diet, alcohol restriction, and quitting smoking can be employed to handle mild elevation. In situations where cholesterol and triglyceride levels are elevated, a low saturated fat diet could be recommended. Depending on an individual's response
to nonpharmacologic therapy, antihypertensive drugs may also be prescribed.
Hypertension can be controlled by effective drugs such as Apresoline and Brodipine. The choice of treatment depends on factors like age, race, and medical history. Neglecting hypertension can result in serious and potentially deadly illnesses. Hence, it is crucial for patients to undergo a thorough evaluation conducted by a medical doctor. This evaluation will aid in determining the most appropriate treatment plan and educating the patient about adopting a healthier lifestyle. By adhering to the prescribed treatment program, patients can enhance their prognosis and experience a more active life.
