Most acute (or temporary) diarrhea is mild and rarely requires antibiotics. You can effectively relieve diarrhea symptoms by restricting what you eat, drinking plenty of fluids, especially electrolyte replacement fluids, and by using an antidiarrheal medication such as IMODIUM®.
In the initial stages (acute phase) of diarrhea, avoid high sugar products, alcohol, whole fruits, vegetables and high fibre foods - they can increase the frequency of diarrhea.
But the most important thing to do during this time is to drink plenty of clear liquids or, even better, use an oral rehydration solution (ORS). Take the ORS frequently in small amounts up to a total of at least 8 to 16 glasses per day (2 to 4 litres). An ORS contains a carbohydrate (glucose or rice syrup) and electrolytes (sodium, potassium, chloride, and citrate or bicarbonate). As your symptoms improve, it can be supplemented with other beverages, including water, unsweetened juices or clear soups. You can find ORS solutions at most pharmacies.
