About Internal Hemorrhoids

Overview

Internal hemorrhoids are swollen veins that develop inside the rectum. They are one of the two types of hemorrhoids, the other being external hemorrhoids. Internal hemorrhoids are typically painless but may become painful if they prolapse or slip outside the anus. They are located within the lining of the anus and lower rectum. Internal hemorrhoids may cause bleeding during bowel movements, and blood in the stool is often the only sign of their presence. These swollen veins can be caused by straining during bowel movements, sitting for long periods of time, chronic constipation, obesity, and a high-stress lifestyle. Treatment options for internal hemorrhoids include lifestyle changes, such as increasing fiber intake and staying hydrated, as well as over-the-counter creams or ointments to relieve symptoms. In some cases, medical procedures may be necessary to remove or shrink internal hemorrhoids. Remember to consult with your healthcare professional for personalized advice and treatment options.

Causes and Risk Factors

Internal hemorrhoids occur within the rectum or inside the anus. The causes of internal hemorrhoids include:

Straining during bowel movements: This puts pressure on the veins in the rectal area, leading to their enlargement and swelling.
Sitting for long periods of time: Prolonged sitting can increase pressure on the veins in the anal area.
Chronic constipation: Straining to pass hard stools can contribute to the development of internal hemorrhoids.

Risk factors for internal hemorrhoids include:

Age: The risk of developing hemorrhoids increases with age.
Family history: Having a family history of hemorrhoids may increase your risk.
Diet: A low-fiber diet can lead to constipation, which in turn increases the risk of hemorrhoids.
Sedentary lifestyle: Lack of physical activity can contribute to constipation and increase the risk of developing internal hemorrhoids.

It's important to note that while these factors can increase the likelihood of developing internal hemorrhoids, they may not be the sole cause. It's always best to consult with a healthcare professional for an accurate diagnosis and appropriate management.

Symptoms

Internal hemorrhoids do not cause pain because they are located in the rectum above the area of sensation. The most common symptom of internal hemorrhoids is painless bright red bleeding with stools or on the toilet paper.

As internal hemorrhoids become more severe, additional symptoms may occur. These can include:

Prolapse of the hemorrhoid, where it protrudes from the anus.
Pain or discomfort, especially during bowel movements.

It is important to note that not everyone with internal hemorrhoids will experience all of these symptoms. Additionally, these symptoms can also be similar to those of other digestive tract problems. If you are experiencing any of these symptoms, it is recommended to consult with a healthcare professional for an accurate diagnosis and appropriate treatment.

Diagnosis

To diagnose internal hemorrhoids, doctors commonly perform the following examinations, tests, and procedures:

Digital Rectal Exam: The doctor inserts a lubricated glove-covered finger into the anus and rectum to feel for signs of hemorrhoids, such as lumps or swelling.
Anoscopy: This procedure involves using an anoscope, a small tube with a light on the end, to examine the lining of the anus and lower rectum. It helps detect internal hemorrhoids and other lower digestive tract problems.

Additional examinations and tests may include:

Sigmoidoscopy: This procedure involves using a flexible tube with a camera to examine the rectum and lower colon. It helps evaluate the extent and severity of internal hemorrhoids.
Colonoscopy: In some cases, a colonoscopy may be recommended to examine the entire colon. It can help rule out other conditions and assess the overall health of the colon.

Other examinations, tests, and procedures may be recommended based on initial findings and individual factors.

Treatment Options

The goals of treatment for internal hemorrhoids are to reduce or eliminate symptoms rather than cure the condition. Here are some recommended treatments and how they work to achieve these goals:

Medications:

Zinc oxide creams: Creams containing zinc oxide can help reduce anal itching associated with hemorrhoids.
Phlebotonic drugs: These medications, usually comprised of plant extracts, may help improve overall symptoms of hemorrhoids and reduce bleeding.
Topical treatments: Over-the-counter hemorrhoid creams, pads with a numbing agent, or hydrocortisone suppositories can provide relief from symptoms.

Therapeutic procedures:

Sclerotherapy: This involves injecting a solution into the hemorrhoids to block blood supply and cause them to shrink.
Infrared photocoagulation: In this procedure, infrared light is used to block blood supply and shrink the hemorrhoids.
Rubber band ligation: A rubber band is placed near the base of the hemorrhoids to cut off blood supply, causing them to shrink and fall off.
Surgical removal (hemorrhoidectomy): This procedure is recommended for severe cases when other treatments have been unsuccessful. It involves removing external or prolapsed internal hemorrhoids.

Self-care and Health Behavior Changes:

High fiber diet: Eating a diet rich in fiber can help soften stools and reduce straining during bowel movements.
Hydration: Staying well-hydrated can prevent constipation and make bowel movements easier.
Good hygiene: Keeping the anal area clean and dry is important for managing symptoms.

It's important to note that these recommendations should be discussed with a healthcare professional before starting any treatment.

Medication dosing may be affected by many factors. Check with your healthcare professional about dosing for your individual situation. Side effects can occur. Check with your healthcare professional or read the information provided with your medication for side effect information.
