Mucus In Your Stool With IBS: Causes & When To Worry [Dr. Farahat]
By Dr. Farahat.
(Q1) Is Mucus In Stool With IBS Is Normal?Answer: In short, yes but not always. Mucus is a natural part of your stool. It is secreted in small amounts by the mucous cells lining your colon and small intestine. In normal conditions, you will not notice mucus in the stool because of its clear color and small amount. And it has beneficial effects:
- Help easy passage of your stool.
- Traps harmful organisms in your gut.
- it is clear white or yellow in color.
- associated with abdominal cramps or tenesmus.
- not associated with red flag signs like:
- blood or pus with mucus.
- nocturnal diarrhea (diarrhea that awakens from sleep).
- weight loss.
(Q2) what are the causes of mucus in stool other than IBS?Answer: Mucus in stools occurs due to a variety of conditions. It is difficult to differentiate between IBS mucus in stool and other causes. This is because the symptoms of IBS are similar to other diseases causing mucus in stool. I will try to break down the major causes of mucus in stools other than IBS. The value from this article is not to substitute medical advice by your doctor, but to:
- Initially help you to evaluate your condition.
- Guide you to know when to consult your doctor.
A- Bacterial infections of your intestine (Gastroenteritis/Bacillary dysentery):Bacterial gastroenteritis is a very common cause of mucus in stool. And it is common for gastroenteritis to be confused with IBS flare-ups. Bacterial gastroenteritis caused by a variety of bacterial species like:
- Salmonella (typhoid fever).
- Shigella (bacillary dysentery).
- Campylobacter Jeujeni.
- And others.
- Abdominal cramps, more intense, not related to meals, and can awaken you from sleep.
- Usually, diarrhea, which is more severe, not related to food (can occur at any time0.
- The mucus in stool may be associated with blood (dysentery).
- Fever usually occurs with bacterial infections. It may be a high-grade fever (exceeds 40° c).
- These infections are foodborne. The severe form is called “food poisoning”.
- If your mucus in stool is associated with the symptoms above you have immediately to consult your doctor.
- Your doctor may ask for a stool sample to define the causative bacteria.
- The condition is usually more severe than the regular IBS flare-up and requires treatment with antibiotics and strong symptomatic treatment.
B- Not drinking or eating for many hours.As we mentioned before, mucus normally presents in small amounts in your stool. The color is clear white or yellow making it difficult to notice. With dehydration, mucus tends to become more think and stool contains less water. Also, the amount of mucus tends to increase relative to stools. At this point, the mucus becomes visible in the stool. Usually, dehydration causes both constipation and mucus in stool. Symptoms:
- Not drinking water or recurrent vomiting for any reason causing dehydration.
- No other symptoms of IBS like colics, bloating and distension.
- No evidence of bacterial infections like fever, vomiting, and severe abdominal pain.
- Usually, the stool is hard with dehydration (constipation), mixed with mucus or preceded by a small amount of mucus.
- The mucus is clear (no pus nor blood).
C- Anal Fissure:An anal fissure is a breakdown in the mucous membrane lining your anal canal. The most common cause of anal fissures is chronic constipation. Anal fissure causes chronic irritation to the inside of your anal canal. This irritation stimulates mucous cells inside your rectum and anus to produce more mucus. So, Mucus in stool with IBS-Constipation may indicate that you have an anal fissure. But the severe pain during defecation is the most specific symptom. Symptoms & differences from IBS mucus:
- The most common presentation of the anal fissure is intense pain during defecation.
- Usually, you have constipation for a long time (anal fissures are more common with IBS-Constipation.
- The mucus in stool usually passes at first then the stool (as it is formed in the last part of your colon).
- Mucus in stool may be associated with bright red blood due to bleeding from the fissure.
- Get an appointment with your doctor to confirm your case by doing an examination of your anal area.
- Your doctor will usually prescribe a topical cream to decrease the pain and relax your anal muscles.
- Also, you should take a laxative to decrease constipation which is the cause of your anal fissure.
C- Inflammatory bowel disease or IBD (Ulcerative Colitis and Crohn’s Disease):IBD is a group of disorders characterized by true inflammation and ulceration of your intestine. It is caused by a faulty immune response to your gut cells and bacteria. Your immunity attacks your own colon and intestine causing ulcers and bleeding. The condition is usually more severe than IBS. it causes mucus in stool with or without visible blood. Symptoms and how it is different from IBS mucus:
- IBD is mainly associated with diarrhea, the diarrhea is not related to food and may awaken you from sleep.
- Mucus in stool is usually not clear; associated with pus or blood.
- Weight loss.
- Iron deficiency anemia (pallor and easy fatigue).
- May be associated with fever.
- The fever, anemia, and weight loss are not present with IBS.
- Weight loss, anemia, fever, and unclear mucus (with pus or blood) are not a part of IBS; you should get tested immediately.
- If you have such symptoms your doctor will ask to do some blood and stool tests.
- Usually, the definitive diagnosis of ulcerative colitis and Crohn’s disease is by colonoscopy.
- Treatment includes a drug called “mesalazine” and in more severe cases steroids and other treatments may be tried.
D- Intestinal obstruction (Uncommon).Intestinal obstruction is a medical emergency. It occurs when your colon or more commonly small intestine gets obstructed. The most common causes of intestinal obstruction are:
- Most commonly (60%): Fibrous adhesions around your bowel loops (especially if you have previous operations inside your abdomen).
- When a bowel loop stuck inside a hernia.
- A block by a cancer mass like colon cancer.
- Volvulus: when stomach or intestine twists around itself.
- The main symptom of intestinal obstruction is “absolute constipation”; when you poop you only pass clear mucus without a stool (unlike mucus in stool with IBS).
- Usually associated with severe distension, abdominal cramps.
- Persistent vomiting usually occurs as the food unable to pass.
(Q3) when should I worry/consult my doctor?Mucus in stool with IBS is usually a benign condition that is a part of your IBS. If you habitually pass mucus in stool with IBS attacks you don’t have to worry. The mucus in stool with IBS is usually clear white or yellow. It is not associated with blood or pus. Consult your doctor in you experience one of the red flags:
- Passage of pus (unclear mucus) with severe tenesmus.
- Passage of blood with mucus.
- Diarrhea associated with fever and/or vomiting.
- Intense pain at the anal canal during defecation (anal fissure).
- Diarrhea with mucus that awakens you after sleeping.
- Persistent vomiting.
- Weight loss, anemia.
- Recent antibiotic use.
- Passage of mucus without stool with severe distension and persistent vomiting (intestinal obstruction).
