Why Does My Poop Burn Like Acid? Why & What to DO!

Your poop burns like acid due to constipation. Your anal lining tends to suffer minor cuts or tear at the exit point of your anus as you excrete.

This results in a sharp, intense pain that might be perceived as a burning sensation at times.

As a result of constipation, your anal lining tends to tear, or minor cuts form at the exit point of your anus. This causes sharp, intense pain that might be perceived as a burning sensation sometimes.

Why Does My Anus Burn When I Poop?

There are several causes of a burning sensation while passing stools, and they include:

  • Spicy Foods

These are the number causes of burning poop.

Foods with high spiciness feature an ingredient known as capsaicin that can irritate your rectal, intestinal, and anal lining while leaving the body with stools.

  • Constipation

Constipation occurs when you have reduced bowel movements, and you end up passing out excrete once in three days, putting more pressure to pass hard stools or pass minimal stools.

These hard stools tend to irritate your mucosa or skin surrounding and inside the anus while you use more force to excrete.

  • Diarrhea

If you pass more than three loose, watery stools within 24 hours, you could very well be suffering from diarrhea.

Diarrhea irritates the delicate lining of your rectal and anal passage, causing a burning sensation while pooping.

  • Anal Fissure

Constipation exerts pressure on your anal lining pushing them to suffer small cuts or tears towards the exit point of your anus.

You will then feel a series of sharp, intense pain that might be perceived as a burning sensation at times.

  • Hemorrhoids

You can suffer enlargement and bulging of blood vessels in and around the anorectal region resulting in hemorrhoids if you:

Use excessive pressure to defecate

Lift heavy weights, frequently

Experience pregnancy

Experience persistent constipation or diarrhea

Once hemorrhoids establish a base, you’re likely to experience pain, burning sensations, and blood in stools (if they rupture) during excretion.

  • Engaging in Activities that Damage the Anal Lining

The following activities tend to damage the anal lining:

Performing anal S.E.X without proper lubrication

Scratching the anus to get relief from worm infestation

  • Colorectal Cancer

This is a life-threatening condition that exhibits a burning sensation while pooping as one of its symptoms.

If you find polyps in your rectal region, they might eventually turn out to be cancer in presence of risk factors.

They also lead to rectal bleeding, altered bowel movements, weight loss, anal discharge, pain with defecation, etc.…, as their symptoms.

Sometimes, they can also be present asymptomatic.

  • Inflammatory Bowel Disease (IBD)

Crohn’s disease and ulcerative colitis are two such conditions that cause inflammation in the lining of the bowel, burning sensation with pooping, bloody stools, altered bowel movements, fecal incontinence, abdominal pain, cramps, etc.

  • Sexually Transmitted Infections

Some sexually transmitted infections like syphilis, gonorrhea, chlamydia, etc., can get transmitted to your anus via unprotected anal sex.

These infections lead to rectal inflammation or anal lining resulting in pooping with a burning sensation.

  • Warts

Warts in the anus can form due to human papillomavirus infection, and these warts cause stinging pain and burning sensation while pooping. HPV infection is also an STI, but under favorable circumstances, it can even lead to anal cancer.

What Other Symptoms Accompany Burning Poop?

Depending on the cause of the burning sensation you’re feeling, other symptoms like these will accompany it:

  • Ulcers and abscesses in the anus.
  • Presence of growths in the anal region.
  • Anal discharge.
  • Bleeding from the anus.
  • Itching in and around the anus.
  • Altered bowel habits (like alternating diarrhea and constipation with altered frequency).
  • Bloody stools.
  • Anorectal pain.

Burning Sensation Around Anus Treatment

Fix up a doctor’s appointment and you will be thoroughly examined to rule out the cause.

The treatment of burning sensation in the anal canal whole defecation is cause-oriented, and simultaneous symptomatic treatment will begin.

Here is an acidic stool remedy for each cause:

  • For diarrhea, you will be prescribed antibiotics. Asides from that, ensure you drink enough water and oral rehydration solution to replenish the lost electrolytes and fluids.

Once diarrhea is treated, your burning sensation should also subside.

  • As for constipation, you need to drink lots of fluids and consume foods rich in fiber content. Laxatives will also be prescribed to ease your bowel movements.

Frequent exercise lets you enjoy better bowel movements.

  • For infections at the anal site, oral and topical antibiotics will be prescribed to solve that.
  • If anal fissures are the cause then topical agents like Benzocaine or Lidocaine and topical nitrates will be prescribed for local application.

This greatly relieves your burning pain or sensation.

Stool softeners, sitz bath, hydration, and a high fibrous diet help relieve the symptoms.

  • Antiseptic ointments can also be applied.
  • In case of warts or polyps, your surgeon might remove them surgically or with lasers and cryotherapy.
  • Are STIs the cause of your burning sensations, your treating physician will prescribe you antibiotics?
  • Use condoms and lubricate adequately while performing anal sex.

Why Does It Burn When I Poop No Spicy Food?

  • Too Much Toilet Paper

Yes! Humans have advanced in terms of anal cleansing, but a lot of people still use two-ply as their main wiping material.

TP can do serious damage to your b-hole if you’re already experiencing diarrhea, which makes you poop anywhere from 3-10 times per day.

Nonstop wiping with rough, coarse material irritates the sensitive skin of your undercarriage, causing micro-tears known as anal fissures.

Now, every time you wipe, the burn feels more intense.

Moral of the story: ditch toilet paper.

  • Hemorrhoids

Strained bowel movements triggered by chronic constipation lead to swollen veins in your anal area.

More than 70% of humans in the world will suffer hemorrhoids sometime in their life, with symptoms ranging from rectal bleeding to an itchy butthole.

If you have a case of the runs, hemorrhoids can cause burning diarrhea. That’s because the stomach acids, enzymes, and bile in diarrhea inflame the already-sensitive tissue in and around your b-hole as it works its way out.

Here are a few home remedies for hemorrhoids:

Wipe your butt with witch hazel-infused wipes. These will help in the reduction of the swelling

Get an over-the-counter (OTC) hemorrhoid cream like Preparation H to soothe the inflammation

Take a sitz bath with lukewarm water

  • Food Poisoning

Almost all forms of food poisoning cause diarrhea.

That’s because of gastroenteritis, which is a fancy way of saying your digestive system feels like it’s on fire.

The longer the infection lasts, the more time you’ll spend on the toilet seat wiping, which then triggers even more burning diarrhea (especially if you’re using dry toilet paper.)

The first aid to food poisoning is having a steady dose of electrolytes and fluids. However, if symptoms such as cramping, stomach pain and chronic diarrhea last longer than a few days, get in touch with your healthcare provider.

  • Digestive Diseases

Some intestinal conditions can cause chronic diarrhea and a host of other tummy troubles like bloating.

Ulcerative Colitis

Crohn’s Disease

Celiac Disease

Irritable bowel syndrome (IBS)

Inflammatory bowel disease (IBD)

Why Does My Poop Burn Like Acid After Drinking Alcohol?

Alcohol agitates the intestines and causes them to react by speeding up the digestion process. Your colon muscles move in a coordinated squeeze to push stool out and alcohol speeds up the rate at which these squeezes occur, thereby, preventing water from getting absorbed by your colon as it would normally.

This causes your stool to come out as diarrhea, often very quickly and with a lot of additional water.

How To Soothe Burning Anus After Diarrhea

Here are a few FoulBowel-approved tips to soothe burning anus after diarrhea and restore your pooping patterns while still alleviating your burning bum.

  • Eat a High-Fiber Diet

Dense carbs and fiber aid in binding food together in your digestive tract so your poop looks more like a smooth brown snake instead of a bowl of brown, burning lava.

So, ditch the coffee, booze, and dairy products because rice, bread, oats, and bananas are your friends for the next couple of days.

Ensure you drink lots of water and electrolytes to replenish the fluids that you’re flushing down the toilet all day.

  • Ditch Toilet Paper

Constant use of dry, scratchy toilet paper is a GUARANTEED way to inflame your Poop-hole.

So, throw them out and grab a pack of Mint Chill wipes to stay clean and soothe your chapped rear at the same time.

  • Let Your Butt Breathe

Without proper ventilation, it’s difficult for the skin around your butthole to heal and stop burning.

Also, avoid wearing tight clothes or pants and makes sure your underwear is breathable.
