A more thorough examination for internal hemorrhoids is done visually using an anoscope, which is similar to a proctoscope, but smaller. Whether or not hemorrhoids are found, if there has been bleeding, the colon above the rectum needs to be examined to exclude other important causes of bleeding other than hemorrhoids such as
Pregnant women can get hemorrhoids during the last 6 months of pregnancy. This is because of increased pressure on the blood vessels in the pelvic area. Straining to push the baby out during labour can make hemorrhoids worse.
A dab of witch hazel applied to the rectum with a cotton ball is one of the very best remedies available for external hemorrhoids, especially if there’s bleeding, says Marvin Schuster, MD. Witch hazel causes the blood vessels to shrink and contract. While anything cold, even water, can help kill the pain of hemorrhoids, icy cold witch hazel provides even more relief. Chill a bottle of witch hazel in an ice bucket or the refrigerator. Then take a cotton ball, soak it in the witch hazel, and apply it against your hemorrhoids until it’s no longer cold, then repeat, suggests Schuster.
Approximately 50% to 66% of people have problems with hemorrhoids at some point in their lives. Males and females are both affected with about equal frequency. Hemorrhoids affect people most often between 45 and 65 years of age. It is more common among the wealthy. Outcomes are usually good. The first known mention of the disease is from a 1700 BC Egyptian papyrus.
These activities limit blood flow around the anal region, causing the blood to pool and the vessels to swell. Pregnant may suffer from hemorrhoids because of the extra pressure the fetus places on the body. Because blood vessels can stretch over time, older individuals are more likely to suffer from hemorrhoids when blood pools in the veins.
Hemorrhoids often get better without surgery or even procedures your doctor can do in the office. Start with over-the-counter products and lifestyle changes. (If you’re pregnant, you should talk to your doctor before you try any medicine or change your diet.)
Recent studies revealed the benefits of tea tree oil in reducing inflammation and curing hemorrhoids naturally. Since it is very strong, it should always be diluted by mixing it with a carrier oil. Add one or two drops of tea tree oil with a carrier oil like castor oil or sweet almond oil and apply it directly over the inflamed area with the help of a clean cotton swab. Doing this regularly will shrink the hemorrhoids until it cures completely. Other essential oils that may have a healing effect are lavender essential oil and rosemary essential oil.
Hemorrhoidectomy: Hemorrhoidectomy is a surgical procedure performed in the operating room with an anesthetic agent (general, spinal or local with sedation) where the whole hemorrhoid is removed (ectomy=removal). This is the most aggressive approach and there is a markedly decreased chance of the hemorrhoids returning. There is a potential for complications with this procedure; however, these occur less than 5% of the time. Complications include infection, bleeding, and stenosis where scarring causes the anus to narrow.
External and internal hemorrhoids are diagnosed by a physical exam and history by a health-care professional. Sigmoidoscopy or colonoscopy may be ordered to look for other causes of blood in the stool.
Acute hemorrhoidal crisis is a rare event that usually requires emergency treatment. The mechanism of action is a large internal hemorrhoid prolapse. The sphincter mechanism squeezes, incarcerating the internal hemorrhoids and strangulating them. The resulting spasm causes edema and occasionally thrombosis of the external hemorrhoids. The resulting pain and swelling are dramatic and very painful. Emergent operative resection is safe and, with conservation of the anoderm, provides good relief. Rapid pain relief with office excision of thromboses and ligation of internal hemorrhoids has been reported.
Rubber band ligation is the most-used remedy for grade II and grade III hemorrhoids and is the standard by which other methods are compared. This procedure is most common in the United States, because it is the most commonly taught method in training programs.  With experience, many third-degree and some fourth-degree internal hemorrhoids can be treated nonoperatively. Although rubber band ligation is effective in 75% of patients in the short term, it does not treat prolapsed hemorrhoids or those with a significant external component. 
Internal hemorrhoids may be painless or even symptomless. However, when symptoms do occur (in both external and internal hemorrhoids), they may include pain, bleeding, itching, or irritation of the anal region. Other symptoms include swelling, trouble controlling bowel movements, and palpable lumps around the anus. Sometimes straining causes an internal hemorrhoid to be pushed outside of the body, and this is called a protruding or prolapsed hemorrhoid. Severe external hemorrhoids may causes a great deal of blood to pool and result in a blot clot (thrombus) that causes intense pain, swelling, or irritation.
Haemorrhoids, commonly known as piles, are swollen blood vessels in or around the anus and rectum. The haemorrhoidal veins are located in the lowest part of the rectum and the anus. Sometimes they swell so that the vein walls become stretched, thin, and irritated by passing bowel movements. Haemorrhoids are classified into two general categories – internal and external.
An external hemorrhoid arises from blood vessels that surround the anus beyond the pectinate line. They do not cause many problems unless they rapidly expand and clot. Usually this clot resolves spontaneously leaving residual skin.

Hemorrhoid or haemorrhoid (also commonly called piles) are vascular structures (similar to veins) in the anal canal which help with stool evacuation. We only speak of hemorrhoids (or piles) when they become swollen or inflamed. But Hemorrhoids are a normal part of the anatomy and everyone has these structures. They act as a cushion that is made of complex tissue. Their job is to aid the passage of stool. Hemorrhoids are very common. Nearly three out of four adults will have hemorrhoids from time to time.
Internal hemorrhoids are typically painless, even when they produce bleeding. You might, for example, see bright red blood on the toilet paper or dripping into the toilet bowl. Internal hemorrhoids may also prolapse, or extend beyond the anus, causing several potential problems. When a hemorrhoid protrudes, it can collect small amounts of mucus and microscopic stool particles that may cause an irritation called pruritus ani. Wiping constantly to try to relieve the itching can worsen the problem.
Excisional hemorrhoidectomy is a surgical excision of the hemorrhoid used primarily only in severe cases. It is associated with significant postoperative pain and usually requires 2–4 weeks for recovery. However, the long-term benefit is greater in those with grade 3 hemorrhoids as compared to rubber band ligation. It is the recommended treatment in those with a thrombosed external hemorrhoid if carried out within 24–72 hours. Evidence to support this however is weak. Glyceryl trinitrate ointment after the procedure helps both with pain and healing.

Hemorrhoids are usually caused by increased pressure on the veins in the pelvic and rectal area. As pressure increases, blood pools in veins and causes them to swell. Eventually, the swollen veins stretch the surrounding tissue, and hemorrhoids develop.
An internal hemorrhoid is a swollen blood vessel that arises from within the rectum above the pectinate line. It causes no symptoms unless there is bleeding with a bowel movement, or if it prolapses and can be felt externally after if protrudes through the anus.
This therapy employs an intense beam of infrared light to shrink hemorrhoids. Infrared light cuts off the blood supply and causes the hemorrhoid to wither away. The downside is the extreme pain experienced right after the procedure. Make sure that your doctor is comfortable with prescribing pain medication immediately following the procedure before you agree to it. Like sclerotherapy, this remedy has developed a lot of attention over the last five to seven years, which should eventually lead to better procedures with less associated pain.
Hemorrhoidal venous cushions are normal structures of the anorectum and are universally present unless a previous intervention has taken place. Because of their rich vascular supply, highly sensitive location, and tendency to engorge and prolapse, hemorrhoidal venous cushions are common causes of anal pathology.  Symptoms can range from mildly bothersome, such as pruritus, to quite concerning, such as rectal bleeding.
Hemorrhoids are normal tissue and only raise concern when they swell, become inflamed or bleed. Hemorrhoids will recur after non-surgical treatment about 50% of the time, while the recurrence rate after surgery is only 5%.
There are many hemorrhoid creams and suppositories on the market, and while they generally will not make your problem disappear, most are designed as local painkillers and can relieve some of the discomfort, says Gathright. Limit their use to 1 week; they can cause the skin to get too thin.
Hemorrhoids can be prevented by keeping the stools soft, by regular exercise, eating a high fiber diet, drinking plenty of fluids; avoiding straining with bowel movements, and trying to avoid sitting for long periods of time, especially on the toilet.
After local anesthetic is placed under the skin surrounding the hemorrhoid, a scalpel is used to cut into the area and the clot is removed. There is almost instant relief of the sharp pain but a dull ache may continue.
