Depending on the symptoms of hemorrhoids and the degree of harm to human health, internal hemorrhoids can be divided into three stages.
1.Stage I, which is painless and is mainly characterized by bleeding, discharge and itching.
2.Stage II, with blood in the stool and hemorrhoids that prolapse with defecation but can be returned on their own.
3.Stage III (also called late stage), the internal hemorrhoid prolapses outside the anal opening, or each time defecation prolapses outside the anal opening, it cannot be returned by itself, and must be held back by hand. In stage IV, the internal hemorrhoid prolapses out of the anal opening and cannot be returned to the inside of the anus. This kind of is the most serious condition among internal hemorrhoids.
The lighter hemorrhoids bring inconvenience to one’s normal life; the heavier ones affect health. If the blood in the stool is prolonged, it can lead to different degrees of anemia and even hemorrhagic shock, which is life-threatening; when the hemorrhoid is necrotic and infected seriously, it can cause systemic infection through the blood system, which has serious consequences. Therefore, when you have hemorrhoids, you need to actively deal with them.
More serious hemorrhoids can lead to or induce cardiovascular disease, especially in elderly patients, such as suffering from hemorrhoids produce psychological pressure, afraid to go to the toilet, and in the long run will aggravate constipation, when defecation occurs with difficulty, the patient force to hold his breath, which can make the heartbeat accelerate causing cerebral vascular rupture, causing cerebral hemorrhage or cerebral embolism; if there is internal hemorrhoids embedded, pain can also induce angina attack; if there is thrombosis, can cause pulmonary embolism.
Hemorrhoids typing
1.Vascular swelling type: internal hemorrhoid surface mucous membrane rough and soft, dark red or vermilion, easy to bleed when touched, this type is the main symptom of bleeding
2, varicose veins type: internal hemorrhoid surface is hard, with glossy, dark red or blue, the hemorrhoid body is varicose hemorrhoid veins and hyperplastic connective
3.Fibrotic type: the surface of internal hemorrhoid is hard and elastic, the surface of hemorrhoid body is slightly white fibrous tissue proliferation, easy to detach, not easy to bleed.
4, thrombosed external hemorrhoids: the main morbidity characteristics are sudden onset, severe pain, swelling and discomfort, and occasionally systemic symptoms. The local examination reveals a bulging swelling next to the anus, a hard and slippery subcutaneous mass can be palpated, and the tenderness is obvious.
5.Inflammatory external hemorrhoid: often caused by anal edge skin injury and infection, mostly anal pain, pain is aggravated during defecation, blood in the stool, and a small amount of anal discharge. Local examination of the raised swelling next to the anus, red in color, obvious congestion, tenderness, sometimes accompanied by general discomfort and fever.
6, varicose veins type external hemorrhoids: the anal edge is raised into an oval shape, soft to touch, painless, dark purple lump can be seen when straining during stool, and the volume can be reduced after defecation or rest, which is caused by subcutaneous varicose veins, also caused by the development of late internal hemorrhoids. The swelling and discomfort are generally felt only when defecating, and painful symptoms only when inflammation occurs.
7.Connective tissue type external hemorrhoids or superfluous external hemorrhoids: The skin folds at the edge of the anus become larger and the connective tissue proliferates, forming many superfluous hemorrhoids of different sizes and shapes.
Reasons for formation
The majority of medical practitioners in China believe that hemorrhoids occur for the following reasons.
1, anatomical reasons: when a person is standing or sitting, the anorectum is located in the lower part, due to gravity and the compression of the organs, the venous upward reflux is quite obstructed. Rectal vein and its branches lack of venous valves, blood is not easy to reflux, easy to stasis. Its vascular arrangement is special and crosses the muscular layer at different heights, which is easily compressed by the fecal mass and affects the blood return. The veins also pass through the loose tissue of submucosa, lack of scaffolding around them, and are easy to expand and flex.
2, genetic relationship: the vein wall is congenitally weak, resistance is reduced, can not tolerate intravascular pressure, and therefore gradually dilate.
3.Occupational relationship: people standing or sitting for a long time, long-term weight-bearing distance, affecting venous reflux, so that the pelvic blood flow is slow and abdominal organs congestion, causing excessive filling of hemorrhoidal veins, the tension of the vein wall decreases, the blood vessels are easy to stasis expansion. And because of the lack of movement, intestinal peristalsis, stool down sluggish, or habitual constipation, can compress and stimulate the veins, so that the local congestion and blood return obstruction, causing hemorrhoid veins within the pressure rise, the vein wall resistance is reduced.
4, local stimulation and diet: the anal part of the cold, heat, constipation, diarrhea, excessive drinking and more spicy food, can stimulate the anus and rectum, so that the hemorrhoid venous plexus is congested, affecting the venous blood return, so that the resistance of the venous wall is reduced.
5, anal vein pressure increase: because of liver stiffness, liver congestion and heart function compensation insufficiency, etc., can make the anal vein congestion, pressure increase, affect the rectal vein blood return.
6, increased intra-abdominal pressure: because of intra-abdominal tumor, uterine tumor, ovarian tumor, prostate hypertrophy, pregnancy, eating too much or squatting too long, etc., can make the intra-abdominal pressure increase, preventing the venous blood return.
