Burning Sensation in Anus

Unfortunately, it is quite common to experience a burning sensation around the anal region. This often occurs during a bowel movement or immediately afterward. At some point in your life, you will most likely experience this type of burning sensation. For most people, this feeling is not a cause for a concern because it often just indicates that you ate spicy food recently.

There are some indicators that mean you should be concerned. If you have bleeding from your rectum or blood in your stool, you should immediately go to your doctor. Likewise, the presence of mucus in your stool if you have diarrhea or constipation could both indicate a more severe medical condition. If you have a burning sensation in the anus without a clear reason why, you should go to the doctor to be diagnosed and to ensure that you are not experiencing a more severe condition.

The Causes of a Burning Sensation in Anus

Your gastrointestinal tract is responsible for helping your process food and remove waste matter. Your anus is the end of the gastrointestinal tract. The large intestine connects to the rectum, which is then also connected to the anus.

There are several reasons why you could experience a burning sensation in your anus. If you scratch the area, it could cause burning sensations, especially if you just had a bowel movement. Infections, skin conditions and eating certain types of food can all lead to a burning sensation. Plus, there are some intestinal and stomach disorders that may cause this sensation.

1. Spicy Foods

One of the most common reasons for this condition is the type of food that you eat. Spicy foods are known to contain certain chemicals that irritate the gastrointestinal mucosa, which ends up leading to irritation, inflammation and redness in the anus. Interestingly, this occurs because of the same reason that you enjoy spicy food. Certain chemicals in spicy foods are known to produce a pain response. When you eat them, the pain response stimulates endophins to be released in your mind which cause pleasure. Thus, the pain of spicy food on your tongue causes you to enjoy it (if you like spicy food, that is).

Unfortunately, these same chemicals can cause a burning sensation during and after bowel movements. The chemical, capsaicin, is found in chili peppers and can cause a burning sensation as well as diarrhea. If you want to limit the pain, try to cut back on the spicy food that you eat.

2. Proctalgia Fugax

This type of medical condition causes a sharp pain to occur within the anus. This pain may last for several seconds or up to 30 minutes. Between each attack, you will most likely not have any pain. You may feel dizzy, wake up from a deep sleep or get a headache because of the pain. You may also feel like you really have to go to the bathroom, but nothing happens when you try to. People who have this condition may have about five to six of these attacks every year.

3. Incontinence

Some people suffer from incontinence of their stool, which means that their bowels are not completely under control. An entire bowel movement or just a small part of liquid stool may unintentionally pass through your anus without you allowing it to. When you suffer from this condition, you may experience a burning sensation. In addition, it is easy to not notice stool that has escaped, and the stool can irritate your skin and lead to burning and itching in the region.

4. Hemorrhoids

When the rectal veins become swollen or weakened, it can lead to a hemorrhoid. This can cause rectal bleeding, diarrhea and chronic constipation. Unfortunately, it can also cause itching and burning sensations. It will most likely feel worse during a bowel movement. There are external and internal hemorrhoids, but you would only be able to see the external hemorrhoids.

5. Infections

Infections can easily cause a burning sensation in your anus. These could be sexually transmitted diseases or other types of infections. Some possible infections that could cause this include streptococcal dermatitis, intestinal parasites, chlamydia, tinea corporis, gonorrhea, tinea cruris and genital herpes. If you have any of these conditions, it is important to seek immediate medical care for your condition.

6. Bowel Conditions

Certain bowel conditions like irritable bowel syndrome, impacted feces, gastroenteritis, rectal prolapse, perianal abscess, fistulas and inflammatory bowel disease could all cause this problem. These diseases could cause symptoms like rectal bleeding, pelvic pain, burning sensations, constipation, diabetes, ulceration of the bowel’s lining, mucus in bowel movements and abdominal pain.

7. Bad Hygiene

Bad hygiene could be the simple explanation for a burning sensation. The fecal matter and bacteria in your bowel movements can easily irritate the mucosa. In addition, these bacteria could lead to a skin infection. The easiest way to prevent this problem from happening is to make sure you wipe yourself completely after each bowel movement. You should also make sure that you get thoroughly clean when you shower and take showers regularly.

8. Anal Fissures

If you have experienced intense diarrhea or constipation lately—or if you are a chronic sufferer of these conditions–, you can end up developing an anal fissure. Anal fissures occur when the mucosal lining becomes torn. This often means that you will experience even worse pain after a bowel movement for a while. Sometimes, you may also experience itching around the anus and rectal bleeding. Even when you are not having a bowel movement, you may still experience pain and burning sensations.

9. Skin Diseases

Skin diseases are a common reason for developing a burning sensation in your anus. As the largest organ in your body, your skin is your body’s first line of defense against outside pathogens and invaders. At times, this will make your skin more susceptible to infections. Certain skin diseases like seborrheic dermatitis and pilonidal cysts can cause itching and burning sensations. Psoriasis and eczema can also affect the anus instead of just the rest of your skin.
