What Are Hemorrhoids?
Hemorrhoids, commonly known as piles, are small, swollen lumps that develop inside or around the anus (rectum). They are widespread and are sometimes compared to varicose veins found in the anal region. The discomfort caused by hemorrhoids can vary depending on their size and location, some may be painless, while others are more troublesome. You can have one or multiple hemorrhoids at once.
Types of Hemorrhoids
Hemorrhoids come in three main forms1: 1. Internal Hemorrhoids, These occur inside the rectum and are often painless but may bleed. 2. Prolapsed Hemorrhoids, These push through the anus and can become visible, especially after using the toilet. They can be quite painful. 3. External Hemorrhoids, These feel like hard lumps but are actually small blood clots under the skin surrounding the anus.
Signs and Symptoms2
If you are experiencing hemorrhoids, you may notice:
- Itching or irritation around the anus
- Pain and discomfort
- Swelling around the anus
- Bleeding during bowel movements (often bright red blood on the toilet paper or streaked on stools)
- A hard lump around the anus
What Causes Hemorrhoids?
Hemorrhoids are primarily caused by increased pressure in the veins surrounding the anus, leading to swelling and inflammation. The most common reason for hemorrhoids is constipation, which causes straining during bowel movements3 and puts pressure on the blood vessels. Pregnancy also increases the likelihood of hemorrhoids due to4:
- Constipation often associated with pregnancy
- Pressure from the growing fetus on the abdomen
- Increased blood flow during pregnancy
- Hormonal changes that relax blood vessels5
Other factors that can raise your risk of developing hemorrhoids include:
- A low-fiber diet, leading to constipation
- Straining during bowel movements
- Prolonged sitting on the toilet
- Getting older
- Being overweight
- Regularly lifting heavy objects
- Anal sex
How are Hemorrhoids Diagnosed?
Diagnosing hemorrhoids generally involves a physical examination of the anus. The methods include6: 1. Digital examination, Your doctor may use a gloved finger to check inside the rectum for any abnormalities. 2. Visual inspection (proctoscopy), A proctoscope (a small tube with a light) is inserted into the rectum to directly visualize hemorrhoids.
Treatment Options for Hemorrhoids
Most hemorrhoids resolve on their own without treatment. However, if you are experiencing mild pain or swelling, these steps may help7,8:
- Increasing your intake of fiber by consuming more fruits, vegetables, whole grains, and drinking plenty of water
- Taking stool softeners to make bowel movements easier
- Warm baths to soothe the affected area
- Over-the-counter hemorrhoid creams that contain local anesthetics for pain relief and corticosteroids to reduce swelling
If these measures do not alleviate symptoms, additional treatments include9:
- Prescription corticosteroid creams for severe inflammation
- Sclerotherapy, where a chemical is injected into the hemorrhoid to shrink it
- Rubber band ligation, where a band is placed around the hemorrhoid to cut off its blood supply, causing it to fall off in a few days
For severe hemorrhoids, a hemorrhoidectomy (surgical removal) may be necessary, typically performed under general anesthesia.
When Should You See a Doctor?
Consult a doctor if you notice any blood during a bowel movement, as this could indicate more serious conditions like bowel cancer. In cases where hemorrhoids are not the cause, a colonoscopy might be recommended. You should also seek medical attention if:
- Hemorrhoid symptoms do not improve with treatment
- You experience changes in bowel habits or the color of your stool
- There is unexplained weight loss
