1. What are hemorrhoids?
Hemorrhoids are not conditions of veins. These are conditions of a vascular structure from arteries, veins, connecting arteries to ease muscles and connective tissue coated with normal epithelial sheets of the anal canal. The venous plexus in the submucosa is supported by elastic fibrous tissue structure. Frequent pressure increases such as straining the bowel, with constant blood stasis will lead to dilatation and formation of hemorrhoids in the lumen of the anal canal. At the same stage, the older, the supporting connective tissue structure is exhausted, the hemorrhoids tuft out of the anal hole moving to internal hemorrhoids.
2. Classification of hemorrhoids
Hemorrhoids have 2 types, comprising internal hemorrhoids and external hemorrhoids.
External hemorrhoids: When the hemorrhoids are placed below the cusp (also noted the anal-rectum), it is called external hemorrhoids. The hemorrhoids are marked with squamous epithelium and are placed below the skin surrounding the anus.
Internal hemorrhoids: If the hemorrhoids originate above the pathway, they are called internal hemorrhoids, and it involves the hemorrhoids with mucous and transitional epithelium.
Classification of hemorrhoids: based on the progression of the hemorrhoids that lie inside or have fallen out of the anus.
- Hemorrhoids level 1: hemorrhoids are located in the anal canal.
- Hemorrhoids level 2: normal hemorrhoids fit in the anal canal when pushing to poop hemorrhoids piles or put out less. When the toilet is finished, the hemorrhoids stand up and indent.
- Hemorrhoids 3: each time you go to the toilet or travel a lot, squat, work hard, the hemorrhoids will go down. To lie down for a new hemorrhoids tufts dropped or pushed with his hand.
- Hemorrhoids 4: hemorrhoids are almost always outside the anal canal.

3. Risk factors for causing hemorrhoids
- Constipation, or diarrhea, raises the number of hemorrhoids, straining increases pressure on the veins, leading to discomfort and stasis.
- A low-fiber diet enhances the regularity of hemorrhoids
- Overweight and obesity, developing disease frequency
- Increased abdominal pressure found in people who often work hard as porters, weightlifters, tennis, …, lasting longer, sitting as much as secretary, tailor, salesman do increase abdominal pressure impedes blood came back to the heart leading to varicose veins of the anus.
- Sub-regional polyps include colorectal carcinomas, uterine tumors, and many months of pregnancy that interfere with blood return to the heart and cause varicose veins.
4. Causes of hemorrhoids
The veins around the anus develop under pressure and may swell or congest. Hemorrhoids may progress because of raised pressure in the lower rectum because of:
- Straining when getting a bowel movement
- Sit for long terms on the toilet
- Chronic diarrhea or constipation
- Anal intercourse
- A diet poor in fiber
- Hemorrhoids increase with age because the tissue formation that holds the veins in the rectum and anus becomes looser and looser.
5. Symptoms of hemorrhoids
Signs and symptoms of hemorrhoids may include:
- Bleeding without pain during bowel movements. At first, discreet amounts of bright red blood can be seen on toilet paper or in the toilet. Bleeding is the earliest and most common symptom. Later, after pushing, blood flows into drops or rays. Heavier than when squatting also bleeds.
- Itching or irritation in the anal region due to mucus from the secretion of the anal canal.
- Pain or discomfort, ranging from no pain, little to very painful due to anal fissure, clogging, or stuffiness.
- Swelling around the anus
- A bulging mass near the anus, burning or pain (possibly a thrombus in hemorrhoid)
Symptoms of hemorrhoids often depend on the location:
External hemorrhoids are most uncomfortable because the skin on the piles is irritated and ulcerated. If a blood clot forms inside external hemorrhoid, the pain can be sudden and severe. The patient may feel or see a bulging mass around the anus. Blood clots may be absorbed, leaving the wrinkled skin irritated and irritated.
Internal hemorrhoids are usually painless, even when they are bleeding (bleeding). The person may, for example, see bright red blood on toilet paper or drip into the toilet bowl.
Hemorrhoids are often not visible or felt, and they are rarely uncomfortable. During straining, the stool that passes through the anus can scratch the surface of the hemorrhoids and bleed. Internal hemorrhoids may also fall out of the anus to create internal hemorrhoids. When the hemorrhoids are prolapsed, it can absorb a small amount of mucus and stool that can cause irritation that causes itching, pain, and burning. Repeated cleaning to try to reduce itching may worsen the problem.
