It is this guide that many people lose the opportunity for prevention and treatment.

Hemorrhoidal patients with hematochezia as the main symptom often have anemia, and if the patients cannot be treated in time, pale complexion, fatigue, dizziness, weakness, sudden standing after long-time sitting and squatting and collapse can be caused along with the increase of blood loss of the patients. Due to prolapse of hemorrhoids and relaxation of anal sphincter, mucus flows out of the anus and irritates the skin, resulting in skin itching and eczema of the anus. If the hemorrhoids are not treated in time, the focus of infection becomes worse continuously, and proctoptosis and rectal mucosa prolapse are formed, so that anal sphincter is relaxed, and anal incontinence is caused. For women, if haemorrhoids bleed or inflammation often causes bacterial mass propagation, various gynecological inflammations such as vaginitis, urethritis, cystitis and adnexitis are caused. If haemorrhoids bleed or inflame, they can cause bacterial proliferation, which can cause inflammation in men, and in addition, pain and discomfort, which can affect quality of life. Prevention and treatment of anorectal diseases is therefore of paramount importance and does not vary in any way.
