3 typical anal canal diseases such as hemorrhoids
Hemorrhoids are generally classified as internal hemorrhoids. External hemorrhoids, mixed hemorrhoids
Hemorrhoids are soft swellings that protrude from the inside and outside of the anus and are formed by stagnant, varicose veins in the anal canal.
Depending on the location of the hemorrhoid, they are generally classified as internal, external, or mixed hemorrhoids, with the main focus here being internal and external hemorrhoids.
The rich venous plexus in the lower rectum and anal canal forms the anal cushion tissue that prevents leakage of stool and waste gas. If you strain too hard during constipation, you can increase the burden on the anal canal, rupture or cause bruising, which can cause the connective tissue around the blood vessels to proliferate. This protruding soft swelling is called a hemorrhoid.
We usually refer to hemorrhoids that occur above the dentate line as internal hemorrhoids and hemorrhoids as external hemorrhoids. The mechanism of occurrence of internal and external hemorrhoids is different.
It is important to note that during the second trimester of pregnancy, internal hemorrhoids can easily form or worsen the symptoms of hemorrhoids because of the pressure of the enlarged uterus on the pelvic veins
If the hemorrhoids are left unattended, the symptoms can become more and more severe, eventually leading to "prolapse" in which the rectal mucosa comes out of the anus during defecation
Symptoms of internal hemorrhoids
Internal hemorrhoids are soft venous masses formed by enlarged varicose and engorged veins above the dentate line. They are usually not painful because they are autonomously innervated. Many people do not realize they have internal hemorrhoids until they bleed or the hemorrhoid nucleus comes out of the anus. Many people do not realize they have internal hemorrhoids until after they bleed or the hemorrhoids prolapse from the anus.

Factors triggering hemorrhoids
The following factors can trigger hemorrhoids and make them worse.
Constipation can lead to excessive straining during defecation, which increases abdominal pressure and obstructs blood circulation in the inferior vena cava, This causes stasis in the venous plexus of the anal cushion, resulting in rapid swelling and thickening of the blood vessels, and the proliferation of connective tissue around the anal canal, eventually forming a hemorrhoid nucleus.
In addition, when dry stool passes through the anal canal, it can scratch the anal canal and cause inflammation, which can lead to the formation of hemorrhoids. nucleus. If you do not have a bowel movement for several days, the stool that remains in the rectum and anal canal for a long time can irritate the mucous membrane of the rectum and the skin of the anal canal and cause inflammation, which can lead to hemorrhoids.
Most people who take a long time to go to the toilet have symptoms of constipation, and some people take 20 to 3 minutes to defecate once. minutes. Longer bowel movements can raise abdominal pressure and cause stasis in the venous plexus, which can easily lead to hemorrhoids.
Maintaining the same posture for a long time
Sitting or standing in the same position for long periods of time can cause stasis in the venous plexus under the skin of the anal canal, which can lead to hemorrhoids. This is why coach drivers, pilots, and typists are prone to hemorrhoids.
In addition, bicycling, horse racing, weight lifting and trumpet playing, which require high abdominal pressure, can also increase the pressure on the anal canal.
Excessive intake of spicy seasonings, alcohol, etc.
Most of the chili peppers in spicy seasonings are not absorbed by the body and are excreted in the stool. Therefore, the residual chili pepper can irritate the anal canal and cause inflammation during bowel movements.
Alcohol is also a trigger for inflammation of the anal canal, and large amounts of alcohol intake may cause diarrhea and further worsen hemorrhoids.
Measures to be taken after the appearance of hemorrhoids
If you have internal hemorrhoids, they usually do not continue to bleed after the bowel movement is over. After using the toilet, you can sit on a comfortable cushion or sponge, or you can elevate your buttocks or lie still to recuperate. You can also use a skimmed cotton ball to plug the anus to enhance the hemostatic effect.
In addition, in order not to increase the burden on the anal canal, eat as much food as possible that can soften the stool and prevent To prevent constipation
To eliminate bruising and keep the anus clean, it is recommended that you take frequent baths or sitz baths. You can also apply ointment to the affected area under the guidance of your doctor to enhance the treatment effect.
Poor circulation in the venous plexus under the skin of the anal canal is the main cause of external hemorrhoids, so it is important to improve blood circulation to treat them. You can improve blood circulation by taking a bath or sitz bath, or you can warm your buttocks with a warm water bag.
For severe pain, you can take common painkillers. In addition, you can apply ointment to the affected area to relieve the pain caused by friction when walking. Although baths and sitz baths can improve the condition, for patients who have started to develop pus, promoting blood circulation in the buttocks can increase the pain and warm stimulation should be avoided.
