When internal hemorrhoid prolapse does not return in time, incarcerated edema, thrombosis, ulcer or infection will occur, and there will be severe pain. External hemorrhoids are generally asymptomatic in the early stage, and occasionally the anus is uncomfortable, but it will be painful when thrombosis and edema occur. In addition, anal foreign body sensation, contaminated underwear and local itching are also common symptoms of various hemorrhoids.
Another main symptom of internal hemorrhoids is prolapse of internal hemorrhoids. The symptoms of internal hemorrhoids are protruding from the anus, internal hemorrhoids being caught by sphincter, and venous reflux being blocked. However, arterial blood continues to be imported, which increases the volume of hemorrhoid core until arterial blood vessels are compressed, forming thrombus, and hemorrhoid core becomes hard and painful, so it is difficult to send it back to anus. Traditionally, it is called "strangulated internal hemorrhoids", but external hemorrhoids are more common in clinic, and thrombosis is often accompanied by pain. When the prolapse of hemorrhoid nucleus cannot be sent back, it is also called "incarcerated hemorrhoid". Generally speaking, drug therapy is suitable for all kinds of internal hemorrhoids, external hemorrhoids and mixed hemorrhoids, and mild (1 2) internal hemorrhoids are the first choice.
For the common symptoms of internal hemorrhoids, drug therapy has a significant effect on relieving pain and stopping bleeding, and also has a good effect on proctoptosis, constipation and itching caused by hemorrhoids. For patients with internal hemorrhoids or mixed hemorrhoids, symptoms can be relieved by reducing edema, but it is basically ineffective for those with severe prolapse.
Drug treatment of internal hemorrhoids can be divided into local treatment and oral drug treatment. External drugs are external drugs, mainly including hydrocortisone (or its derivatives), lubricants, mucosal protective agents and traditional Chinese medicines, generally suppositories and ointments. It has the functions of diminishing inflammation, stopping bleeding, relieving pain and itching, and relieving the feeling of anal swelling and defecation obstruction caused by hemorrhoid edema.
Local drug therapy is generally used to relieve symptoms in the short term, and should not be used as long-term and preventive drugs. It should be noted that if constipation occurs during the symptoms of hemorrhoids, local application of laxatives is not recommended, and targeted treatment must be carried out. If hemorrhoids recur, local drug treatment is still effective.
Oral drugs include increasing dietary fiber intake, improving intestinal function of patients with hemorrhoids, diminishing inflammation, and using intravenous accelerant. Dietary fiber refers to dietary fiber that is not digested and absorbed by the intestine. It can prevent excessive absorption of water in the intestine, relieve symptoms such as bleeding and pain, and prevent its attack.
It is suitable for patients with intestinal dysfunction such as diarrhea or constipation. Venous enhancer can improve microcirculation and relieve local edema. It can be used for short-term treatment of internal hemorrhoids (pain, bleeding and prolapse), but it can not be used for a long time. If hemorrhoids are accompanied by local inflammation, antibiotics or non-steroidal anti-inflammatory drugs can be used, and the latter can also effectively relieve the pain caused by hemorrhoid thrombosis.
It should be emphasized that drugs can alleviate the symptoms of internal hemorrhoids, but they cannot fundamentally eliminate hemorrhoids. In addition, although the drugs for treating hemorrhoids are relatively safe at present, they still need to be selected and used under the guidance of doctors.
