What Causes Hemorrhoids?

Haemorrhoids, hemorrhoids, emerods, or piles are swelling and inflammation of veins in the rectum and anus. The anatomical term "hemorrhoids" technically refers to "Cushions of tissue filled with blood vessels at the junction of the rectum and the anus". However, the term is popularly used to refer to varicosities of the hemorrhoid tissue. Perianal hematoma are sometimes misdiagnosed and mislabeled as hemorrhoids, when in fact they have different causes and treatments.

It is not known why hemorrhoids enlarge. There are several theories about the cause, including inadequate intake of fiber, prolonged sitting on the toilet, and chronic straining to have a bowel movement (constipation). None of these theories has strong experimental support. Pregnancy is a clear cause of enlarged hemorrhoids though, again, the reason is not clear. Tumors in the pelvis also cause enlargement of hemorrhoids by pressing on veins draining upwards from the anal canal.

Sitting for long periods of time can start the hemorrhoid process. One theory proposes that it is the shearing (pulling) force of stool, particularly hard stool, passing through the anal canal that drags the hemorrhoidal cushions downward. Increased straining during bowel movements caused by constipation or diarrhea may lead to hemorrhoids. It is thus a common condition due to constipation caused by water retention in women experiencing premenstrual syndrome or menstruation.

Another theory suggests that with age or an aggravating condition, the supporting tissue that is responsible for anchoring the hemorrhoids to the underlying muscle of the anal canal deteriorates. With time, the hemorrhoidal tissue loses its mooring and slides down into the anal canal.

Hypertension, particularly portal hypertension, can also cause hemorrhoids because of the connections between the portal vein and the vena cava which occur in the rectal wall -- known as portocaval anastomoses. Pregnancy may lead to hypertension and increase strain during bowel movements, so hemorrhoids are often associated with pregnancy.

One physiological fact that is known about enlarged hemorrhoids that may be relevant to understanding why they form is that the pressure is elevated in the anal sphincter, the muscle that surrounds the anal canal and the hemorrhoids. The anal sphincter is the muscle that allows us to control our bowel movements. Obesity can be a factor by increasing rectal vein pressure. Poor muscle tone or poor posture can result in too much pressure on the rectal veins.

It is not known, however, if this elevated pressure precedes the development of enlarged hemorrhoids or is the result of the hemorrhoids. Perhaps during bowel movements, increased force is required to force stool through the tighter sphincter. The increased shearing force applied to the hemorrhoids by the passing stool may drag the hemorrhoids downward and enlarge them.

Cigarette smoking during bowel movements, may worsen hemorrhoid, may lead to severe internal bleeding of veins inside rectum area. Both can cause diarrhea. Note that caffeine ingestion increases blood pressure transiently, but is not thought to cause chronic hypertension.

Recent improved analytical methods have enabled studies on the traceability and safety of natural products, thus enhancing the acceptance of these natural commodities. Nature’sPharma has notably broadened its scope over the years and continues to be at the forefront of the natural health sector.

Comprehensive efforts in research and development have demonstrated that many plant extracts and natural substances are safe and effective medicines. Moreover, NaturesPharma's specific products continue to yield significant results. HemorrhoidBalm-Rx and AntiHemorrhoidDrops are therefore established as true efficacious anti hemorrhoid treatments.

HemorrhoidBalm-Rx and AntiHemorrhoidDrops derive their uses from the action of complex naturally occurring sesquiterpene and diterpene components. They improve microcirculation, capillary flow, and vascular tone, and strengthen the connective tissue of the rectum. They represent an affordable and realistic treatment option to time-consuming, painful, and expensive complications of hemorrhoids.

HemorrhoidBalm-Rx is for topical application and the primary treatment. AntiHemorrhoidDrops are a dietary supplement homeopathic remedy and to be taken as needed for more acute or chronic conditions. Scientific studies further quantify NaturesPharma’s hemorrhoid extracts produce superior results to eliminate hemorrhoids verse prescription medication and the most popular natural remedies.

The botanical extracts in these treatments have been shown to improve microcirculation, capillary flow, and vascular tone, and to strengthen the connective tissue of the perivascular amorphous substrate.
