Blood supply in the rectum, across the anal-rectal pathway and the entire anal canal is composed of a dense network of blood vessels, including veins and arteries. When these veins are subjected to excessive pressure, hemorrhoids occur. Thus, these veins are referred to as hemorrhoidal veins. The veins within the rectum and upper end of the anorectal region are referred to as the Internal Hemorrhoidal veins. When these veins become swollen or ballooned, they protrude, inducing pain and a burning sensation and might even rupture, causing bleeding, establishing a condition referred to as Internal Hemorrhoids.

Internal Hemorrhoid Symptoms

Internal Hemorrhoids are more difficult to decode since they are not palpable and cannot be seen as easily as External Hemorrhoids. Severe pain or anal itching surfaces when Internal Hemorrhoids have progressed to some extent, underling the fact that early diagnosis of this condition is rather difficult. Chances of bleeding due to hemorrhoids are slightly more among cases of Internal Hemorrhoids than External Hemorrhoids. While feeling a lump or anal discomfort is the first set of symptoms in External Hemorrhoids, red spots of blood appearing on the toilet paper or stools is the primary symptom in Internal Hemorrhoids.

Internal Hemorrhoids Causes

Internal Hemorrhoids are typically caused by straining too hard when seated on the toilet seat. This usually happens among people suffering from constipation which in turn, is caused by lack of dietary fiber and insufficient water-intake. Internal Hemorrhoids might cause leakage of mucus that is suggestive of increased infection in the tissues covering the affected blood vessels. Such hemorrhoids often surface temporarily among pregnant women.

Advanced Stage of Internal Hemorrhoids

The only time Internal Hemorrhoids are palpable is when the hemorrhoid gains enough size to protrude through the anal opening. This is referred to as prolapse of Internal Hemorrhoids. Such large Internal Hemorrhoids protruding through the anal sphincter are more common among the elderly. The underlying cause of this protrusion is the gradual weakening of internal musculature due to aging, including that of the anal sphincter. Prolapsed Internal Hemorrhoids present different degrees of severity. For instance, some are minimally prolapsed and can be pushed back, within the anus, manually. Prolapsed Hemorrhoids are more likely to hurt in a manner similar to External Hemorrhoids.

Please note that Internal Hemorrhoids can be easily prevented by making some easily adoptable changes in your lifestyle, dietary and bowel habits. Further, Internal Hemorrhoids can be effectively treated at home. Read about natural ways of relieving internal hemorrhoid with best and safe Hemorrhoid Treatments.
