Hemorrhoid is a fairly common disease; proctologists believe that more than half of people sooner or later face it. The more a person spends in a sitting position and leads an inactive way of life, the more likely the appearance of hemorrhoid.
The mechanism of occurrence
Walls of veins passing in the rectum for various reasons can expand and lose their tone. Gradually they increase in size, stretch and protrude the mucous membrane and eventually completely exit. During the act of defecation, lifting the gravity injures the mucous membrane and bleeding develops. Also, due to inadequate vasoconstriction, the blood flow slows down, worsens and forms a thrombosis.
Causes, factors of development
Hemorrhoid can be a professional hazard for those who work at a computer, lift heaviness or require constant walking. The risk zone includes such specialties as programmers, loaders, dancers, accountants and so on.
In addition to the external load, there is also internal, associated with problems in the body itself. One of such negative factors is coprostasia. It is a difficult bowel movement, can last a long time and bring tremendous discomfort. During defecation a person tries to facilitate the process with additional attempts, which leads to the protrusion of hemorrhoid. Inflammation and tumors of the lower intestine can contribute to the expansion of hemorrhoidal veins. Disturbance of the mucous membrane of the anal opening is an irritating factor under the action of which the sphincter contracts and the vessels are clamped.
In addition to all of the above, you should not forget about bad eating habits. Acute food and alcohol dilate the veins of the rectum, reduce their muscle tone and already by a known scheme contribute to the prosperity of hemorrhoid.
Pay attention: Pregnancy is the most common cause of the pathology in the female population. The enlarged uterus pushes the rectum downward and presses it towards the pelvis and squeezes the vessels. During labor, the load reaches the highest level, which adversely affects the condition.
The main thing that worries the patient is bleeding from the anus, especially during defecation, discomfort or pain. In addition, the constant itching and burning sensation, the sensation of a foreign body, worry. Outwardly, the doctor sees the so-called hemorrhoidal flower, the petals of which are hemorrhoidal nodes bulging outward.
A doctor resorts to the rectal examination, additionally prescribes blood and stool tests. In rare cases, colonoscopy is performed.
The main preventive measures will be the rejection of bad habits, timely treatment to the doctor about the concomitant diseases, rational nutrition and active lifestyle in non-working hours as an unloading organism.
