Why Does My Butt Smell?

Rectal itching is normally a symptom that produces a strong urgency to scratch the area around your anus, and often leads to a smelly bottom. The condition is sometimes the result of a skin condition such as eczema, a bacterial infection, or even hemorrhoids. More often, it is just a matter of sweat and poor hygiene. If you are noticing an offending odor and asking "why does my butt smell?" then you'll have to take some corrective measures to avoid any embarrassment as a result.

Why Does My Butt Smell?

1. Sweat and Poor Hygiene

The eccrine glands around the anus produce odorless sweat. However, if you also have poor hygiene, this sweat can mix with bacteria or fecal matter resulting in a foul odor. More importantly, if the sweat is allowed to build up over a period of time, bacteria and germs will accumulate, leading to maceration or chronic itching that leads to a secondary infection. Cleanliness is key to avoiding this sweat from becoming a real problem. You will want to make sure that you have thoroughly cleaned up after any bowel movement or excessive sweating.

2. Hemorrhoids

Hemorrhoids are a common ailment, and some people have had to deal with the discomfort, itching, and bleeding that can signal the presence of hemorrhoids. Even the tiniest amount of feces can irritate hemorrhoids, and itching in the perianal area is one of the most common symptoms.Furthermore, external hemorrhoids sometimes keep the anus from closing completely, which can allow some leakage, creating an unpleasant odor.

3. IBS

Irritable bowel syndrome, a digestive disorder, is typically identified as an abnormal increase in the mobility of the intestines, and this disorder is common in about 50% of all gastrointestinal problems. There is no disease present, and only the function of the intestines is affected. However, common symptoms include:

  • Gastrointestinalgas
  • Bloating
  • Cramps and abdominal pain
  • Mucus in the stool
  • Alternating bouts of constipation and diarrhea

IBS can sometimes be a chronic condition; however, for most people there will be times when the symptoms are worse, and times when they can disappear altogether.

4. Proctitis

When asking "why does my butt smell" proctitis could be the cause. Proctitis is an inflammation of the rectum lining, and is common in people who have inflammatory bowel diseases. Other causes may include sexually transmitted infections and symptoms can be temporary, or become chronic. It can cause rectal pain, along with a continuous sensation that you need to have a bowel movement, rectal bleeding, and pain on the left side of your abdomen.

5. Gluten Intolerance

Gluten is a protein found primarily in grains such as wheat, rye, barley and cross contaminated oats. If a person has gluten intolerance, this protein can cause digestive problems such as abdominal pain, gassiness, or diarrhea. The same symptoms are associated with celiac disease, so it's important to get the correct diagnosis.

6. Ulcerative Colitis

A disease that causes inflammation and ulcers in the lining of the large intestine is called ulcerative colitis, and usually affects the lower section of the colon and rectum. Symptoms could include blood and pus in stools, abdominal cramping and pain, and a sensation of an urgent need to defecate. Some patients experience fever, diarrhea, and weight loss.

7. Antibiotics

Medicines that kill bacteria are called antibiotics, and antibiotics can also cause Clostridium difficile colitis, a swelling and irritation of the colon. Antibiotic associated diarrhea and infection are frequent complications of antibiotic therapy because the antibiotics kill the normal bacteria in your intestine, and allow the bad bacteria to grow unabated. Symptoms include fever, diarrhea, and abdominal cramps.

Always consult and report any sudden change in bowel habits or unusual odors to your health care provider to rule out any health conditions that need immediate attention. This is only a partial list of possible causes, and there are many others that may present a life threatening condition such as colon cancer.
