What are the best fluids for diarrhea?

4 min read

According to the World Health Organization, oral rehydration therapy (ORT) is one of the most effective ways to prevent dehydration caused by diarrhea. Selecting the right fluids is a crucial step towards recovery for both adults and children.

Quick Summary

This guide outlines the optimal fluids to consume and those to avoid when managing diarrhea to prevent dehydration and support a faster recovery. It covers commercial and homemade electrolyte solutions, clear broths, and key fluids to reintroduce slowly.

Key Points

  • Prioritize Oral Rehydration Solutions: ORS drinks like Pedialyte contain the perfect balance of electrolytes and sugar to help your body absorb fluid effectively and combat dehydration.

  • Alternate with Clear Broths: Plain chicken, beef, or vegetable broths provide fluid and sodium, helping to replenish some lost electrolytes.

  • Dilute Fruit Juices: If using fruit juice, opt for low-sugar varieties like apple juice and dilute them with water to prevent high sugar content from worsening diarrhea.

  • Avoid Dehydrating Beverages: Stay away from alcohol, caffeine (coffee, strong tea), and high-sugar drinks (sodas) as they can worsen fluid loss and irritate the digestive system.

  • Exercise Caution with Dairy: Diarrhea can cause temporary lactose intolerance, so it's best to avoid milk and most dairy products during recovery.

  • Sip, Don't Gulp: Drinking fluids slowly and in small, frequent amounts helps prevent stomach irritation and nausea.

  • Monitor for Dehydration Signs: Watch for symptoms like extreme thirst, fatigue, dizziness, or reduced urination, especially in vulnerable groups like children and the elderly.

The Importance of Fluid Replacement During Diarrhea

Diarrhea is characterized by loose, watery stools, which cause the body to lose a significant amount of water and essential electrolytes like sodium and potassium. This fluid loss can quickly lead to dehydration, a serious condition that can cause complications ranging from fatigue and kidney problems to, in severe cases, seizures or death. Therefore, replenishing lost fluids and electrolytes is the most critical step in treating diarrhea. Simply drinking plain water may not be enough, as it doesn't replace the lost salts and minerals needed for proper bodily function.

Best Fluid Options for Diarrhea

Oral Rehydration Solutions (ORS)

Oral Rehydration Solutions are specifically formulated to have the correct balance of salts and sugars to maximize absorption by the small intestine. Products like Pedialyte are popular and effective options. You can also create a homemade ORS, though commercial options often have a more precise balance.

Clear Broths and Soups

Chicken, beef, or vegetable broths are excellent choices because they are a source of both water and electrolytes. Opt for broths with lower sodium to avoid worsening dehydration. Broths provide nourishment while being gentle on the stomach.

Electrolyte-Enhanced Beverages

Besides formal ORS, some other beverages can help, though they should be used with care due to their sugar content. Sports drinks like Gatorade can be used, but diluting them with water is recommended to lower their sugar concentration. Coconut water that contains electrolytes is another option.

Weak, Decaffeinated Teas

Certain mild, decaffeinated teas can be soothing and provide hydration. Ginger tea has been shown to have beneficial effects on upset stomachs and can be a good choice. Chamomile tea is another option. However, strong, caffeinated teas should be avoided, as caffeine can act as a mild laxative.

Low-Sugar Juices

Some fruit juices, like low-sugar apple juice, can be consumed in moderation, but they should be diluted with water. High-sugar fruit juices can draw more water into the intestines, potentially worsening diarrhea.

The Importance of Gradual Reintroduction

It's important to reintroduce fluids slowly, especially after vomiting has subsided. Start with small, frequent sips to allow your stomach to adjust. For infants, continuing breast or bottle feeding is recommended.

Fluids to Avoid During Diarrhea

It is just as important to know what fluids to avoid as it is to know what to consume. Certain drinks can irritate the digestive system, worsen dehydration, or simply do not provide the necessary electrolytes for recovery.

  • Caffeine: Found in coffee, strong teas, and some sodas, caffeine can stimulate intestinal contractions, making diarrhea worse.
  • Alcohol: Acts as a diuretic, which promotes fluid loss and can lead to increased dehydration.
  • High-Sugar Drinks: Including many sodas, energy drinks, and undiluted fruit juices, these can cause more water to be drawn into the intestines, worsening symptoms.
  • Milk and Dairy Products: Diarrhea can cause temporary lactose intolerance, so it's best to avoid most dairy products until symptoms have cleared. Yogurt with probiotics may be an exception for some people.
  • Artificial Sweeteners: Sugar alcohols and other artificial sweeteners can have a laxative effect on the digestive system and should be avoided.

Comparison of Diarrhea Fluid Options

Fluid Type Pros Cons Best For
Oral Rehydration Solution (ORS) Precisely balanced electrolytes, scientifically proven efficacy. Can be unpleasant tasting for some. Replenishing lost fluids and electrolytes most effectively.
Clear Broth Provides sodium, potassium, and fluid; easy to digest. Not a full electrolyte replacement; can be high in sodium if not careful. Mild cases, and as a gentle supplement to water.
Diluted Fruit Juice Some electrolyte content, palatable. High sugar content can worsen diarrhea if not diluted. Alternating with ORS or water for taste.
Weak, Decaf Tea Soothing, gentle on stomach, hydrating. Lacks substantial electrolyte content. Staying hydrated and calming the stomach.
Plain Water Essential for hydration, no added sugar. Does not replace lost electrolytes alone. Used in conjunction with other electrolyte-rich fluids.

Homemade Oral Rehydration Solution

If commercial solutions are unavailable, a homemade version can be made carefully. A recipe from the University of Virginia School of Medicine includes 1/2 teaspoon of salt, 1 teaspoon of baking soda, 2 1/2 tablespoons of sugar, and 1 cup of orange juice mixed into two quarts of water. Another option is a simple salt and sugar solution: mix 1/2 teaspoon of salt and 6 teaspoons of sugar into a liter of clean water. It is crucial to use clean water and accurate measurements, as incorrect ratios can be ineffective or even harmful. These solutions are effective for treating dehydration.

Conclusion: Prioritize Electrolytes for Efficient Rehydration

When dealing with diarrhea, the primary goal is to prevent and reverse dehydration, which means prioritizing fluid intake that also replaces lost electrolytes. Oral rehydration solutions (ORS) are the gold standard due to their scientifically formulated balance of salts and sugars. However, clear broths, diluted fruit juices, and weak decaffeinated teas can also play a supportive role in your recovery. Equally important is avoiding fluids that can aggravate the condition, such as caffeinated beverages, alcohol, and high-sugar drinks. For infants and children, consulting a pediatrician is always recommended, but continued breast or formula feeding is typically advised. By being mindful of your fluid choices, you can effectively combat dehydration and help your body recover faster.
