Understanding why anal fissure happen help you prevent this painful condition. Many peoples in Pakistan suffer from fissure because of lifestyle and diet habits. In this article, we explain all main causes of anal fissure in simple language so you can avoid them.
Main Causes of Anal Fissure
1. Hard Stool and Constipation (Most Common Cause)
This is number one reason why fissure happen. When you pass very hard stool, it stretch and tear the delicate skin around anus. Think of it like trying to push big ball through small hole – something will tear.
In Pakistan, constipation is very common problem because:
- We eat lot of rice and meat but less vegetables
- Our traditional diet lack fiber
- Many peoples don’t drink enough water in hot weather
- Office workers sit whole day without movement
When stool become hard like stone, it damage anal canal while coming out. This create tear that take time to heal. If constipation continue, tear never get chance to heal properly and become chronic fissure. According to medical experts at Mayo Clinic, chronic constipation is one of the leading causes of anal tears and related complications.
2. Chronic Diarrhea (Loose Motions)
Too much diarrhea also cause fissure. This surprise many peoples – they think only hard stool cause problem. But frequent loose motions irritate anal area severely.
Why diarrhea cause fissure:
- Acidic stool burn sensitive skin
- Too many bathroom visits damage area
- Wiping too much irritate skin
- Area stay moist which prevent healing
Conditions like IBS (irritable bowel syndrome), Crohn’s disease, or food poisoning cause chronic diarrhea that lead to fissure.
3. Childbirth in Women
During normal delivery (vaginal birth), lot of pressure occur on pelvic floor and anal area. This pressure can cause fissure. Many new mothers don’t realize they have fissure – they think pain is normal after delivery.
Risk more if:
- Baby is large size
- Delivery is prolonged
- Using forceps during delivery
- Multiple pregnancies close together
Women should not ignore anal pain after delivery. Proper treatment help avoid chronic problems.
4. Straining During Bathroom
Pushing too hard is very common cause. Many people have bad habit:
- Sitting long time on toilet reading newspaper or phone
- Forcing when stool not ready to come
- Holding breath and pushing hard
- Rushing bathroom visit and straining quickly
This excess pressure tear anal tissue. Each time you strain hard, you damage area little bit. Over time, this create fissure.
5. Not Drinking Enough Water
Dehydration is big problem in Pakistan, especially in Karachi hot weather. When you don’t drink enough water:
- Stool become dry and hard
- Body absorb more water from colon
- Bowel movement become difficult
- You need strain more
Doctors recommend drinking 8-10 glass water daily. In summer or if you exercise, need more. Many Pakistani drink chai instead of plain water – but tea can dehydrate you more.
6. Low Fiber Diet
Fiber make stool soft and bulky. It help stool move smoothly through intestines. But traditional Pakistani diet often lack enough fiber.
Common low fiber foods we eat:
- White rice (instead of brown rice)
- White bread and naan
- Lots of meat but less vegetables
- Processed and fast foods
Without enough fiber, stool become hard and small. This lead to constipation and eventually fissure. You need 25-30 grams fiber daily from fruits, vegetables, and whole grains.
7. Tight Anal Sphincter Muscles
Some peoples born with naturally tight anal muscles. This cause two problems:
- Tight muscle reduce blood flow to area
- Less blood mean slow healing
- Muscle spasm make fissure worse
- Create vicious cycle of pain and spasm
This is why some fissures become chronic even with good home care. Tight muscle prevent natural healing. These cases need medical treatment like GTN cream or surgery to relax muscle.
8. Age-Related Changes
As peoples get older, blood flow to anal area reduce. Tissues become less elastic. This make older adults more prone to fissure. Also older peoples often have:
- Chronic constipation
- Less physical activity
- Multiple health conditions
- Medications that cause constipation
9. Inflammatory Bowel Diseases
Some medical conditions make fissure more likely:
Crohn’s Disease: Cause inflammation throughout digestive system. Can lead to fissures that don’t heal easily.
Ulcerative Colitis: Cause inflammation and ulcers in colon. Frequent diarrhea from this condition damage anal area.
These fissures different from normal ones – they:
- Located in unusual positions (side instead of front/back)
- Multiple fissures present
- Don’t respond to normal treatment
- Need special medical care
10. Anal Infections
Rarely, infections cause fissure:
- Tuberculosis (TB) of intestines
- HIV/AIDS causing weakened immunity
- Sexually transmitted infections
- Anal abscess that burst
If fissure not healing or you have fever, discharge, this might be cause. Need proper testing.
11. Anal Cancer (Very Rare)
In very rare cases, what look like fissure is actually anal cancer. This is why doctor examine carefully if:
- Fissure not healing after 8 weeks treatment
- Fissure in unusual location
- You have weight loss, night sweats
- Lump or hard area around fissure
Don’t panic – anal cancer very rare. But this is why you should see doctor for fissure that not healing.
Risk Factors That Increase Your Chances
Some things make you more likely to get fissure:
- Young adults: Peak age 20-40 years
- Pregnant women: Due to constipation and delivery
- People with chronic constipation: Main risk factor
- Sedentary lifestyle: Sitting job without exercise
- Previous fissure: If you had before, more likely to get again
- Family history: Some families more prone
How Causes Lead to Chronic Fissure
Understanding cycle help prevent chronic fissure:
- Hard stool or straining cause initial tear
- Tear is painful, so you avoid bathroom
- Holding stool make it harder
- Next bathroom visit cause more damage
- Anal muscle go into spasm from pain
- Spasm reduce blood flow
- Less blood mean slow healing
- Fissure become chronic
Breaking this cycle early is key. That why home treatment important in first few weeks. For complete treatment guide, see our article on anal fissure treatment options.
