Intestinal Segment: Explanation, role, and structure
===================================================================
The rectum, the final section of the large intestine closest to the anus, plays a crucial role in storing feces until defecation occurs. However, it is not uncommon for various conditions to affect this area, causing discomfort and inconvenience.
Rectal Prolapse
One such condition is rectal prolapse, where the rectum slips out through the anus. Symptoms include protruding tissue, bleeding, anal discomfort, fecal incontinence, and mucus discharge. Rectal prolapse is typically due to a weakening of the muscles that support the rectum, and there are three types: external, mucosal, and internal.
Anal Fissures
Anal fissures are small tears in the anal lining, causing severe pain during bowel movements, burning or itching sensations, bright red blood on toilet paper, and visible cracks or skin tags near the anus.
Hemorrhoids
Hemorrhoids are swollen veins that can bulge in the rectum and anus and may cause symptoms such as bleeding, discomfort, and pain. They can be internal or external, with external hemorrhoids potentially becoming very painful if thrombosed, leading to swelling that lasts for weeks and sometimes leaving a skin tag.
Anal Abscesses and Fistulas
Anal abscesses and fistulas result from blocked glands causing infection, leading to sharp, burning pain, sometimes with fever or chills. Treatment for anal abscess usually involves a doctor cutting and draining the pus-filled cavity.
Skin Conditions
Skin conditions like eczema and psoriasis around the anus cause dry, scaly patches, leading to burning pain and irritation.
Sexually Transmitted Infections
Sexually transmitted infections such as anal herpes, anal warts (HPV), chlamydia, gonorrhea, and syphilis can cause itching, burning pain, and other rectal symptoms.
Other Causes
Other causes of rectal symptoms include poor hygiene or overly aggressive cleaning, leading to irritation and discomfort.
Rectal Cancer
Rectal cancer is a condition where cancer cells form in the tissues of the rectum. Symptoms include pain, changes in bowel habits, bright red blood in stool, leaks of diarrhea, and constipation. If a person is over the age of 50 years, they may want to consider discussing regular screening for rectal cancer with their doctor.
Fungal Infections
Fungal infections can affect the rectum and rectal tissues, with examples including candidiasis and cryptococcosis.
Maintaining Rectal Health
To maintain rectal health, people can practice good anal hygiene, maintain a nutritious, balanced diet, avoid smoking, avoid alcohol, maintain a moderate body weight, exercise regularly, and practice safer sex.
In conclusion, various conditions can affect the rectum, causing symptoms such as pain, bleeding, itching, and discharge. Medical evaluation is often required for accurate diagnosis and treatment. If a person is experiencing any rectal discomfort or symptoms that may indicate a problem around the anal area, they should contact a doctor for a diagnosis.
