Patients with [disease name] usually appear [general appearance]. Physical examination of patients with [disease name] is usually remarkable for [finding 1], [finding 2], and [finding 3].

OR

Common physical examination findings of [disease name] include [finding 1], [finding 2], and [finding 3].

OR

The presence of [finding(s)] on physical examination is diagnostic of [disease name].

OR

The presence of [finding(s)] on physical examination is highly suggestive of [disease name].

Physical Examination

• Physical examination of patients with [disease name] is usually normal.

OR

• Physical examination of patients with [disease name] is usually remarkable for:[finding 1], [finding 2], and [finding 3].
• The presence of [finding(s)] on physical examination is diagnostic of [disease name].
• The presence of [finding(s)] on physical examination is highly suggestive of [disease name].

Appearance of the Patient

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

Vital Signs

• Hypotension
• Fever
• Orthostasis

Assessment of dehydration

• Dehydration is the major cause of morbidity and mortality in diarrhea.
• Every patient with diarrhea should be assessed for signs, symptoms, and severity.
• Common findings on physical exam: Lethargy, depressed consciousness, diminshed skin turgor, sunken anterior fontanel, dry mucous membranes, sunken eyes, lack of tears, and delayed capillary refill are obvious and important signs of dehydration.

	Mild dehydration (<5%)	Moderate dehydration (5-10%)	Severe dehydration
Eyes	Normal	Sunken	Very sunken
Mouth	Moist	Dry	Very dry
Tears	Present	Absent	Absent
Thirst	Normal	Thirsty	Poor

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 normally 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
