Diarrhea is typified by increased frequency of bowel movement and loose, watery stools.
What causes Diarrhea?
This is caused by the intestines not absorbing enough fluid, producing too much fluid or stool moving too quickly through the intestine for fluid to be absorbed. Acute diarrhea is the most common form, with bout usually lasting 1-2 days. Chronic diarrhea can last for 4 or more weeks and is often a sign of a more serious underlying illness.
Traveller’s Diarrhea is a name given to a type common among people travelling to countries with poor sanitation and warm climates . Traveller’s diarrhea is usually caused by E.Coli bacteria.
As diarrhea is so common, testing usually isn’t necessary. For chronic or frequent bouts, you may want to see a doctor to find out if there is an underlying cause. This testing may involve blood or urine testing , a fasting test to see if a food allergy may be responsible, or a stool sample to check for bacterial infection or disease. For severe cases, a colonoscopy (a check of the entire colon) or a sigmoidoscopy (a check of the rectum and lower colon) may be necessary to check for intestinal diseases.
Aside from an increased need to go to the bathroom and loose, watery stools, there are a number of secondary symptoms that may present as well. These include nausea , abdominal pains and cramps, bloating, a fever and dehydration . Depending on the severity, you may experience one or more of these secondary symptoms.
