Diarrhea affects all of us from time to time and is generally transient in nature, treated successfully by over-the-counter medications or altered diets. Patients generally seek medical attention when their diarrhea becomes more pronounced, prolonged, associated with fever, abdominal pain or rectal bleeding. There are many different conditions that can lead to diarrhea, so when you visit your doctor, a detailed and accurate history is important. Your doctor will likely ask about the frequency, volume, duration and consistency and quality of the stool along with associated symptoms such as blood, mucous, pus, abdominal pain, fever, weight loss, etc. Knowledge of your medications is important, especially if there has been a change recently, as these can certainly affect your bowel habits. Be sure to tell your doctor about any other underlying medical conditions you may have, as this could be involved or result in diarrhea, as well. In that regard, all medical problems, past surgeries and family history are important factors in considering the cause for diarrhea. Other important factors: Travel history Diet Medications (prescription and over-the-counter) Psychological stress A thorough dietary history is important to know. Certain poorly-absorbed foods may bring on symptoms of diarrhea. Your doctor will likely perform a physical examination to evaluate your vital signs, temperature, and overall physical condition, with particular attention to the abdomen. He may also ask for stool samples for culture and the detection of blood. Diarrhea is classified as either acute or chronic in nature.
