Gastroenteritis is a self-limiting illness that will resolve by itself. Symptoms of uncomplicated gastroenteritis can be relieved with adjustments in diet, herbal remedies, and homeopathy.
An infusion of meadowsweet (Filipendula ulmaria) may be effective in reducing nausea and stomach acidity. Once the worst symptoms are relieved, slippery elm (Ulmus fulva) can be used to calm the digestive tract.
The homeopathic remedies Arsenicum album, ipecac, and Nux vomica are also believed to relieve the symptoms of gastroenteritis.
In Chinese herbal medicine, the patent remedies Po Chai and Pill Curing can be effective for relieving nausea and diarrhea.
Supplementing the bacteria that are beneficial to a person’s health (probiotics) is recommended during the recovery phase of gastroenteritis. Specifically, live cultures of Lactobacillus acidophilus are said to be effective in soothing the digestive tract and returning the intestinal flora to normal. In fact, in 2002, a study found it was reasonably effective in treating children with acute infectious diarrhea. L. acidophilus is found in live-culture yogurt and in capsule or powder form at health food stores. Castor oil packs applied to the abdomen can reduce inflammation, spasms, and discomfort.
It is important to stay hydrated and nourished during a bout of gastroenteritis. In the absence of dehydration, it should be sufficient to drink generous amounts of nonalcoholic fluids, such as water or juice. Caffeine should be avoided, since it increases urine output.
The traditional BRAT diet-bananas, rice, applesauce, and toast-is tolerated by the tender gastrointestinal system, but it is not particularly nutritious. Many, but not all, medical researchers recommend a diet that includes complex carbohydrates (rice, wheat, potatoes, bread, and cereal, for example), lean meats, yogurt, fruit, and vegetables. Milk and other dairy products shouldn’t create problems if they are part of the normal diet. Fatty foods or foods with a lot of sugar should be avoided.
These recommendations are based on clinical experience and controlled trials, but are not universally accepted.
