Overview

Patients with acute diarrhea usually appear ill, dehydrated or lethargic. Common physical examination findings of acute diarrhea include hypotension and other signs of volume depletion (depressed consciousness, sunken anterior fontanelle, dry mucous membranes, sunken eyes, poor skin turgor and delayed capillary refill), abdominal tenderness and distension, increased peristaltic activity (borborygmi).

Physical Examination

Physical examination of patients with acute diarrhea shows signs of dehydration (dry mouth and tongue, sunken eyes, sunken anterior fontanelle, poor skin turgor, hypotension, altered consciousness, absent tears), abdominal tenderness and distension, increased peristaltic activity, perineal erythema and signs of malnutrition.

Appearance of the patient

  • Patients with acute diarrhea may appear ill, dehydrated, or lethargic depending upon the severity of diarrhea.

Vital signs

Assessment of dehydration:[1][2]

Mild dehydration (<5%) Moderate dehydration (5-10%) Severe dehydration
Eyes Normal Sunken Very sunken
Tears Present Absent Absent
Thirst Normal Thirsty Poor
Mouth Moist Dry Very dry
Urine output Normal Decreased Oliguric
Fontanelle Normal Sunken Sunken
Respirations Normal Tachypnea Tachypnea
Mental status Normal Irritable Altered
Blood pressure Normal Hypotension Hypotension

Skin

  • Skin examination of patients with diarrhea can be done by pinch test.
  • If the skin on the thigh, calf, or forearm is pinched, it will immediately return to its normal flat state when the pinch is released in normal patients.
    • Mild dehydration (0-5%): Pinch retracts immediately
    • Moderate dehydration (5-10%): Pinch retracts slowly
    • Severe dehydration (>10%): Pinch remain folded
  • Delayed capillary refill
