One loose motion is equal to one glass of ORS. Most summer diarrhea is watery, effortless and painless diarrhea with no mucous or blood. They need no antibiotics. The only treatment is oral rehydration solution (ORS).

One loose motion is equivalent to loss of one glass of fluid. If a patient has passed 10 loose motions, he needs 12 glasses of ORS apart from normal requirement of fluids and one glass for every loose motion passed again.

For up to 12 loose motions, a patient can be managed as an outpatient but if the loose motions are more than 12, he needs observation and if the numbers of loose motions are more than 40, he needs intensive treatment.

The main complication is renal shut down, which will happen if the blood pressure remains low for more than few hours. During loose motions one should maintain passing of urine every 6-8 hours. If no urine is passed for 8 hours it may indicate an impending renal failure.
