Is Lime Water Good for Diarrhea?

Partly, if you can tolerate it: lime water can help replace fluid lost during diarrhea, but it does not treat the cause. It is an option for hydration, not a proven diarrhea remedy. See the basic lime water recipe for preparation details.

Is lime water helpful when you have diarrhea?

Lime water may be useful if its flavor makes it easier for you to drink. The benefit comes from the water, not from a demonstrated effect of lime on diarrhea. Plain safe drinking water is also an option if the acidity bothers you.

Diarrhea can cause losses of both fluid and electrolytes. Lime water does not provide the carefully balanced salts and glucose found in an oral rehydration solution, so it should not be relied on by itself when those losses are significant. Read more about the best drinks for diarrhea.

How might lime water help?

Drinking lime water adds fluid that your body can absorb to help replace water lost in loose stools. Staying hydrated supports normal body functions, but it does not stop diarrhea or address an infection or another underlying cause.

An oral rehydration solution works differently: its balance of glucose and electrolytes helps the intestine absorb water and replace some of what is lost. A commercial solution prepared according to its package instructions is a more appropriate choice when electrolyte replacement is needed. Mixing lime into water does not create an oral rehydration solution.

What does the evidence say about lime water and diarrhea?

There is no clinical evidence establishing that lime water stops diarrhea, shortens an episode or treats its cause. Its possible benefit is practical hydration, rather than a proven effect on bowel symptoms.

Research on a lime ingredient or concentrated extract would not, by itself, establish that a lightly infused drink works. The amount of lime compounds in infused water can differ from the amount in a whole lime or an extract, and findings about one form should not automatically be applied to another.

How should you use lime water during diarrhea?

If you want lime water, use safe drinking water and make it mild enough that you can tolerate it. Take small, frequent sips if drinking a larger amount at once feels uncomfortable. Do not wait for an infusion to steep before replacing lost fluid or seeking care when needed.

If diarrhea is frequent or you are concerned about dehydration, use a commercial oral rehydration solution as directed and contact a healthcare professional for advice. Mix it with the exact amount of safe water stated on the package; do not substitute lime water or add lime to the prepared solution.

Mild lime-infused water

Ingredients

• 1 liter (about 4¼ cups) safe drinking water
• 1 lime, washed and sliced

Steps

1. Wash the lime under running water and slice it with a clean knife.
2. Add the slices and water to a clean container.
3. Refrigerate for 2–4 hours, then strain out the lime slices to limit bitterness.
4. Keep the water refrigerated and drink it within 24 hours. Discard it sooner if it becomes cloudy, slimy or sour-smelling.

You can use fewer lime slices for a milder taste. If lime water worsens discomfort, stop drinking it and choose a tolerated fluid instead.

Who should be careful, and when should you see a doctor?

Seek urgent medical care for blood or black, tarry stool; severe abdominal pain; confusion or unusual sleepiness; fainting; or signs of significant dehydration, such as very little urine or severe dizziness. Seek urgent help if vomiting prevents you from keeping fluids down, or if diarrhea occurs with a high fever and you feel very unwell.

Infants and young children can become dehydrated quickly. Contact a pediatrician promptly about diarrhea in an infant, and seek urgent care for signs such as unusual drowsiness, little urine or no tears. Continue usual breast milk or formula unless a clinician advises otherwise; lime water is not a substitute.

Older adults, pregnant people, and anyone with a weakened immune system should seek medical advice early. People with kidney disease, heart failure or a prescribed fluid restriction should ask their clinician how to replace fluids safely. If you take a diuretic or medicines for diabetes, ask for advice rather than changing or stopping medication on your own.

For anyone, contact a healthcare professional if diarrhea is not improving, is getting worse or makes it hard to drink enough. Do not rely on lime water while waiting for symptoms of dehydration to become severe.
