Oral Rehydration Salt for Diarrhea

Diarrhea carries water, sodium, chloride, and sometimes potassium out of the body. Oral rehydration solution combines glucose with electrolytes so the intestine can absorb fluid more effectively, even while loose stools continue. It treats the fluid loss rather than stopping bowel movements. This distinction matters: a person may still have diarrhea while becoming better hydrated. The mixture must be prepared at the strength printed on the sachet because too much or too little water changes the balance of the solution.

Mix the full sachet with safe water using the exact volume on the label. Give frequent small sips and offer more after each loose stool, adjusting the approach if nausea makes drinking difficult. If the person vomits, wait a short while and try again with smaller amounts. Continue breastfeeding and ordinary food as tolerated; plain water alone does not replace all the salts lost in diarrhea. Avoid adding sugar, salt, juice, or milk unless the instructions specifically permit it. Do not rely on oral rehydration solution as a substitute for assessment when warning signs are present.

Seek urgent care for blood or black stool, severe or worsening abdominal pain, confusion, fainting, unusual sleepiness, or inability to drink. Very little urine, a dry mouth, marked dizziness, or repeated vomiting can indicate dehydration. Arrange prompt medical advice when diarrhea is persistent, severe, or affecting a baby, older adult, or person with a major health condition. A clinician can assess the cause and decide whether additional treatment or fluids are needed.

Ask how much solution to offer, how long to continue it, and whether current medicines should be adjusted during diarrhea. Check which changes in stool, urine, alertness, or drinking should trigger same-day care.
