Diarrhea Symptoms

• Watery, liquid stools: The stools may be of any color. The passage of red stools suggests intestinal bleeding and could be a sign of a more severe infection. The passage of thick, tarry black stools suggests significant bleeding in the stomach or upper portions of the intestine and is not usually caused by acute infections.
  
  
• Abdominal cramps: Occasionally diarrhea is accompanied with mild-to-moderate abdominal pain. Severe abdominal pain is not common and, if present, may suggest more severe disease.
  
  
• Fever: A high fever is not common. If present, the patient may have a more severe illness than acute diarrhea.
  
  
• Dehydration: If diarrhea leads to dehydration, it is a sign of potentially serious disease.

• Examples of signs and symptoms of dehydration include:
  
  
  • Adults may be very thirsty and have a dry mouth.
    
    
  • The skin of older people may appear to be loose. Elderly may also become very sleepy or have behavior changes and confusion when dehydrated.
    
    
  • Dehydrated infants and children may have sunken eyes, dry mouths, and urinate less frequently than usual. They may appear very sleepy or may refuse to eat or drink.
