What Test Do Doctors Use to Find The Cause of Diarrhea?
To help determine the cause of diarrhea, your doctor may run the following tests.
STOOL TEST
The presence of blood, microbes, parasites, or signs of infection can be detected through stool testing. You will be provided with a vessel by a healthcare professional to catch and store the stool. You will receive instructions on where to send or take the vessel for investigation.
HYDROGEN BREATH TEST
This test is utilized to analyze lactose intolerance by measuring the quantity of hydrogen in your breath. Small amounts of hydrogen can usually be detected in the breath.
With lactose intolerance, undigested lactose produces a high level of hydrogen in your breath. This test requires you to drink a beverage with a required amount of lactose. This hydrogen level is measured in a balloon-like container which you breathe into.
There’s a rare chance that the hydrogen level is high, your doctor will analyze lactose intolerance.
BLOOD TEST
Blood samples may be taken by a health-care professional to test for diseases or disorders that can cause diarrhea.
FASTING TEST
To find out if a nutrient intolerance or allergy is the cause of diarrhea, then your doctor may inquire you to maintain a strategic distance from nutrients with lactose, carbs, wheat, or other ingredients to determine if it improves.
ENDOSCOPY
Depending on the cause of diarrhea, your doctor may perform an endoscopy on you.
Endoscopic strategies incorporate
1: Colonoscopy
2: Flexible endoscopy
3: Upper gastrointestinal endoscopy
