What is the treatment for gastroenteritis?

Although most people with gastroenteritis require no formal treatment, the key to a more rapid and safe recovery is good hydration. Home treatment consists of adequate fluid intake so that dehydration is prevented. The recommended fluids are clear fluids (Pedialyte, especially for young children, Gatorade, Powerade, and other similar drinks) but not fruit juices or milk. If dehydration occurs, the affected individual should be evaluated by a health care professional, who is likely to begin IV rehydration, the treatment of choice for rapid rehydration.

Medications may be prescribed to reduce the symptoms of gastroenteritis, for example, promethazine (Phenergan), prochlorperazine (Compazine) or ondansetron (Zofran) may be prescribed to reduce vomiting. Some physicians suggest using these only as a suppository (or IV) since patients frequently just vomit the pills up. Others may prescribe diphenoxylate and atropine (Lomotil) or loperamide (Imodium) to slow diarrhea. Many doctors simply suggest no treatment for gastroenteritis symptoms as all of the drugs have side effects, and the doctors figure that if the patient stays well hydrated, the symptoms will soon resolve.

Once the gastroenteritis symptoms abate, especially vomiting, doctors recommend a BRAT diet (bananas, rice, apples and toast) for a day or two before beginning a regular diet.

Individuals that have more serious symptoms, or other symptoms in addition to gastroenteritis need to be evaluated, diagnosed, and treated by a physician because the patient will likely have a specific disease that will need treatment. The treatment will depend on the cause of the illness, (for example, salmonellosis or Clostridium difficile). Administration of antibiotics and other treatments may be contraindicated for some of these diseases, so an accurate diagnosis is important. For Clostridium difficile infected patients, antibiotic sensitivity testing may need to be ordered to determine the most effective antibiotics to use since many strains are resistant to these drugs.

I got gastroenteritis while I was on vacation. Vomiting and severe diarrhea. When I got home I went to my GI doctor because by that time it had been 5 days and I was getting dehydrated. He gave me Flagyl and within a couple of days I was feeling much better.

I"ve had the stomach flu for 6 days now. First day was vomiting profusely and diarrhea at the same time. After several hours I decided to go to the hospital. I was so dehydrated the doctor admitted me for the night, gave me some Phenergan and fluid through IV. I felt better the next day, just exhausted from the night's events. I vomited so hard that the blood vessels in my face and eyes busted, so I looked rather gross as blood pooled in the whites of my eyes. By day 3 I was a lot better, just had no appetite and slept a lot. Day 4 and 5 I finally ate solid food and was able to keep it down. Day 6 I still have diarrhea and my stomach is making loud gurgling sounds with bad gas. Not sure what that"s about, but I feel 90% better and will return to work on Monday after being out for four days.
