What are the symptoms and manifestations of irritable bowel syndrome?

Irritable bowel syndrome (IBS) is a functional gastrointestinal disorder characterized by recurrent abdominal pain linked to altered bowel habits, without detectable structural or biochemical abnormalities. Symptoms fluctuate over years, often beginning in adolescence or early adulthood, and can significantly impair quality of life while sparing life expectancy.

  1. Cardinal features
  • Abdominal pain or discomfort: crampy, aching, or sharp, usually located in the lower abdomen; episodes last minutes to hours and are relieved by defecation.
  • Change in bowel frequency: patients may experience >3 loose stools daily or <3 stools weekly; the pattern can alternate within the same individual.
  • Change in stool form: using the Bristol scale, types 6–7 (mushy/watery) during diarrhea spells and types 1–2 (hard/lumpy) during constipation spells are typical.
  • Sensation of incomplete evacuation: persistent urge after bowel movement, leading to repeated visits to the toilet.
  • Visible abdominal distension: objectively measured increase in girth by evening, often accompanied by tight clothing.
  1. Subtypes based on predominant habit
  • IBS-D: >25 % of bowel movements loose and <25 % hard.
  • IBS-C: >25 % hard and <25 % loose.
  • IBS-M (mixed): both loose and hard stools >25 % of the time.
  • IBS-U: insufficient criteria for above categories.
  1. Associated non-colonic symptoms
  • Upper GI: early satiety, nausea, epigastric burning overlapping with functional dyspepsia.
  • Genitourinary: frequent urination, urgency, dyspareunia.
  • Gynecologic: dysmenorrhea intensifying IBS pain mid-cycle.
  • Fatigue, headache, and sleep disturbances: independent of stool pattern.
  1. Symptom triggers
  • Food: fatty meals, caffeine, sorbitol, onions, garlic, beans, wheat, milk (via either lactose or FODMAP effect).
  • Stress: examinations, job interviews, or personal conflicts can precipitate flares within hours.
  • Hormonal: many women report worsening perimenstrually.
  • Post-infectious: 10 % of acute gastroenteritis cases evolve into IBS through low-grade inflammation and altered microbiota.
  1. Red flags that exclude IBS
    Age >50 at first onset, nocturnal pain awakening from sleep, bloody stools, unintentional weight loss, anemia, elevated inflammatory markers, or family history of colorectal cancer, celiac disease, or inflammatory bowel disease—these mandate further investigation.
  2. Daily-life impact
    Symptoms often peak during working hours; fear of incontinence leads to avoidance of long commutes or social events, creating a cycle of anxiety and heightened gut sensitivity.

What Are the Symptoms of Acute Appendicitis?

Acute appendicitis results from luminal obstruction followed by bacterial overgrowth and rapid inflammation. Cardinal features in chronological order are:

  1. Migratory pain
    Vague periumbilical or upper-abdominal discomfort migrates to the right lower quadrant within 4–6 h and intensifies with movement, coughing or palpation.
  2. Gastro-intestinal upset
    Anorexia, nausea and often vomiting; loose stools or constipation may mislead toward gastroenteritis.
  3. Fever
    Low-grade 37–38 °C early, rising >38.5 °C as inflammation advances; elderly or immunocompromised patients may remain afebrile.
  4. Peritoneal signs
    Maximal tenderness at McBurney point, rebound pain, guarding and hypo-active bowel sounds indicate parietal peritoneal irritation.
  5. Systemic toxicity
    Tachycardia, malaise, thirst; high fever with pallor or hypotension suggests gangrene or perforation with sepsis.
  6. Special populations
    Pregnancy displaces the appendix upward, shifting pain to the right upper quadrant; infants present with irritability, refusal to feed and high fever.

Perforation risk rises sharply after 48 h; any sustained abdominal pain with fixed right-lower-quadrant tenderness warrants urgent evaluation.

FeatureTypical Findings
Pain onsetPeriumbilical → right lower quadrant
QualityDull early, later sharp, worsened by cough
GI symptomsAnorexia, nausea, vomiting, ± diarrhea
FeverLow → moderate, may exceed 38.5 °C
Peritoneal signsTenderness, rebound, guarding at McBurney
Alarm signsHigh fever, hypotension, diffuse pain (perforation)
ImagingUS/CT: enlarged appendix >6 mm

What Are the Symptoms of Peritonitis?

Peritonitis is an acute inflammation of the peritoneum triggered by bacterial, chemical or physical insults. It progresses rapidly and may become life-threatening within hours. Key manifestations include:

  1. Abdominal pain
    The earliest and most prominent symptom—persistent, sharp, and diffuse; movement, coughing or palpation intensifies the discomfort.
  2. Peritoneal signs
    Tenderness, rebound pain and guarding give the abdomen a board-like rigidity, reflecting parietal peritoneal irritation.
  3. Nausea & vomiting
    Initially reflex, later bilious or feculent if paralytic ileus supervenes.
  4. Fever & rigors
    Temperature often >38 °C with chills as systemic inflammation ignites.
  5. Abdominal distension
    Gas and fluid accumulate when peristalsis ceases, sometimes compromising respiration.
  6. Cessation of flatus & stool
    Absent bowel sounds confirm adynamic ileus.
  7. Dehydration & thirst
    Fluid loss from vomiting, third-spacing and fever produces dry mucosa and oliguria.
  8. Systemic toxicity & shock
    Endotoxaemia may lead to septic shock: pallor, cold clammy extremities, tachycardia, hypotension, confusion, culminating in multi-organ failure.
  9. Dialysis-fluid changes (in CAPD patients)
    Cloudy effluent with fibrin flecks or strands and catheter-site erythema.

Because fulminant deterioration is common, any patient with sudden severe abdominal pain plus fever, guarding or haemodynamic instability requires immediate evaluation and empiric therapy.

Key AspectTypical Findings
Pain onsetSudden, severe, continuous, worsened by motion
Physical signsTenderness, rebound, board-like rigidity
GI functionNausea, vomiting, absent flatus/stool, silent abdomen
Temperature≥38 °C, often with chills
CirculatoryTachycardia, hypotension → septic shock
RespiratoryShallow breathing due to pain/diaphragmatic splinting
Urinary outputOliguria from hypovolaemia or sepsis
Emergency markerCombination of acute abdomen + fever/shock mandates urgent laparotomy/IV antibiotics

What Are the Symptoms of Retroperitoneal Hematoma?

The clinical presentation of retroperitoneal hematoma is often nonspecific. Mild cases may show only vague discomfort, while severe cases can quickly progress to hemorrhagic shock. Main manifestations include:

  1. Abdominal pain – the most frequent symptom, usually steady and dull, located in the upper, lower or flank abdomen and sometimes radiating to the back .
  2. Low-back pain – caused by direct compression or irritation of lumbar muscles and nerves .
  3. Abdominal distension & decreased bowel sounds – due to paralytic ileus secondary to hematoma compression or irritation .
  4. Hypovolemia & shock – the retroperitoneal space can conceal >2 L of blood; patients may suddenly develop pallor, tachycardia, hypotension and even collapse .
  5. Nerve compression – femoral neuropathy with anterior thigh pain, numbness or weakness when the hematoma extends into the iliac fossa .
  6. Urinary symptoms – hematuria, dysuria or acute urinary retention if the kidneys, ureters or bladder are involved .
  7. Peritoneal irritation signs – muscular guarding, rebound tenderness and absent bowel sounds when the hematoma is large or ruptures into the peritoneal cavity .
  8. Late complications – infection, multiple organ dysfunction or re-bleeding may appear if the hematoma is not promptly managed .

Because of this variability, any patient with lumbar-abdominal trauma, pelvic/spinal fracture, persistent abdominal-flank pain, unexplained shock or paralytic ileus should be evaluated for retroperitoneal hematoma, preferably by emergency CT.

What Are the Symptoms of Intestinal Obstruction?

The classic picture of intestinal obstruction is “pain, distension, vomiting, and absence of stool/gas.”

Abdominal pain: forceful peristalsis in the proximal bowel causes colicky pain every 5–15 min; persistent severe pain suggests ischemia or perforation.

Distension: gas and fluid accumulate proximal to the blockage, inflating the abdomen; low obstructions produce greater swelling and visible peristaltic waves.

Vomiting: high obstructions provoke early, frequent emesis—first gastric, then bilious or feculent; low obstructions delay vomiting.

Obstipation: complete obstruction abolishes flatus and stool; residual distal content may be passed early.

Auscultation reveals hyperactive, high-pitched, metallic bowel sounds; peritoneal signs or systemic toxicity warn of strangulation or perforation.

Key SymptomDescription
Colicky abdominal painIntermittent cramps every 5–15 min
Abdominal distensionMore marked in distal obstruction
VomitingEarly & bilious (high), late & feculent (low)
ObstipationNo flatus or stool in complete obstruction
Hyperactive bowel soundsHigh-pitched, metallic on auscultation
Peritoneal signsPersistent pain, guarding → possible strangulation

What Are the Symptoms of Appendicitis?

Almost every acute appendicitis begins with abdominal pain: initially dull or vague around the umbilicus; in roughly 70-80% of adults it migrates to the right lower quadrant (McBurney point) within 6-8 h and is worsened by coughing, walking, or pressure. Sudden spread suggests possible perforation.

Nausea, vomiting, and loss of appetite accompany the pain; vomitus is usually gastric, and children may vomit more often.

Temperature is usually low-grade (37-38℃); with suppuration or perforation it may exceed 38.5℃ and be accompanied by chills and malaise.

Altered bowel motility causes constipation or diarrhea; a pelvic appendix may irritate the rectum, producing tenesmus and urinary frequency.

When inflammation reaches the peritoneum, rebound tenderness and guarding appear; board-like rigidity with absent bowel sounds signals diffuse peritonitis.

An inflammatory mass or abscess may be palpated in the right lower quadrant with local warmth, indicating peri-appendiceal abscess.

Specific signs include Rovsing (right lower pain on left-side compression), psoas (pain on hip extension), and obturator (pain on hip flexion–internal rotation) signs.

Elderly patients feel less pain and may appear only mildly ill despite gangrene; in pregnancy the appendix is displaced upward, so pain is higher than the classic McBurney point.

What Are the Symptoms of Intestinal Fistula?

An intestinal fistula is an abnormal passage between the bowel and another organ or the skin, allowing digestive fluid, food residue, or stool to leak, producing a spectrum of clinical manifestations.

The most common symptom is abdominal pain, usually persistent or colicky, located in the segment where the fistula arises.

Diarrhea is frequent, with watery or pasty stools caused by loss of digestive fluid and reduced absorptive surface.

Fever indicates accompanying infection, presenting as remittent or sustained high temperature, often with chills.

Rapid weight loss with fatigue and poor appetite results from malabsorption and hyper-catabolism.

When the tract opens into the bladder, pneumaturia, fecaluria and recurrent urinary tract infections occur; when into the vagina, passage of gas, fluid or stool is noted.

A cutaneous opening on the abdominal wall or perineum drains feculent fluid continuously, causing local pain, erosion, and excoriation.

In the acute postoperative phase sudden severe abdominal pain, guarding, tachycardia and hypotension may signal diffuse peritonitis or sepsis.
