Are Milkshakes Good for Stomach Viruses? The Answer is No

5 min read

Over 50% of the world's adult population suffers from lactose malabsorption, and during a stomach virus, this can become even more pronounced. So, are milkshakes good for stomach viruses? The short answer is no, and consuming one can actually make your symptoms worse.

Quick Summary

Fatty, sugary dairy products like milkshakes can inflame the digestive system and worsen symptoms of a stomach virus. Opt for bland, easily digestible foods and clear liquids to promote hydration and recovery.

Key Points

  • Avoid Milkshakes: The dairy, high sugar, and fat content in milkshakes can worsen stomach virus symptoms like nausea, diarrhea, and bloating.

  • Embrace Bland Foods: Stick to easy-to-digest foods like bananas, rice, applesauce, and toast (the BRAT diet) to help your stomach recover.

  • Focus on Hydration: Small, frequent sips of water, broth, or electrolyte drinks are crucial to combat dehydration caused by vomiting and diarrhea.

  • Delay Dairy Reintroduction: After symptoms subside, wait at least 48 hours before gradually reintroducing dairy to allow the digestive system to heal.

  • Don't Rush Recovery: Pushing a regular diet too soon can cause a relapse of symptoms; follow a step-by-step reintroduction plan.

  • Prioritize Rest: The body needs ample rest to fight off the viral infection and recover properly from the fatigue and weakness associated with the illness.

Why Are Milkshakes Bad for a Stomach Virus?

When you're dealing with a stomach virus, or viral gastroenteritis, your digestive system is inflamed and highly sensitive. Introducing foods that are difficult to digest can exacerbate symptoms like nausea, vomiting, and diarrhea. Milkshakes combine three primary irritants: dairy, sugar, and fat.

Lactose Intolerance

During an intestinal illness, many people experience a temporary intolerance to lactose, the sugar found in dairy products. The virus can damage the intestinal lining, leading to a temporary reduction in the enzyme (lactase) needed to break down lactose. Consuming dairy, even if you normally can, can cause gas, bloating, and increased diarrhea.

High Sugar Content

The high sugar content in milkshakes is another major issue. Large amounts of sugar can pull water into your intestines, which worsens diarrhea. This can increase dehydration, a primary concern during a stomach virus.

High Fat and Greasy Foods

Lastly, milkshakes are high in fat. Fatty and greasy foods are notoriously difficult for the stomach to process, especially when it's already irritated and inflamed. These foods can delay gastric emptying, leading to increased nausea and vomiting.

What to Eat and Drink When You Have a Stomach Virus

Instead of a milkshake, the focus should be on staying hydrated and consuming bland, easy-to-digest foods. A common approach is the BRAT diet, which stands for Bananas, Rice, Applesauce, and Toast.

Staying Hydrated with Clear Liquids

  • Oral Rehydration Solutions: Products like Pedialyte are specifically designed to replace lost fluids and electrolytes.
  • Clear Broths: Chicken or vegetable broth can provide sodium and other minerals lost through vomiting and diarrhea.
  • Herbal Teas: Peppermint or ginger tea can help soothe an upset stomach.
  • Water: Small, frequent sips of water are essential to prevent dehydration.

Slowly Reintroducing Bland Foods

  • Bananas: Easy to digest and rich in potassium, which is lost during dehydration.
  • Rice: Plain white rice is low in fiber and easy on the stomach.
  • Applesauce: A good source of pectin, a type of soluble fiber that can help firm up stool.
  • Toast: Dry, plain white toast is a simple carbohydrate that is gentle on the digestive system.
  • Saltine Crackers: These can help settle the stomach and provide a little salt to help replace electrolytes.

When to Reintroduce Dairy

Most healthcare professionals advise avoiding dairy products for at least 48 hours after your symptoms have resolved. The lactase enzyme needs time to rebuild in your gut. When you do reintroduce dairy, do it gradually and start with plain, low-fat yogurt with live cultures. The probiotics in yogurt can be beneficial for restoring gut health. Watch for any returning symptoms and back off if needed.

Comparison: Milkshake vs. Electrolyte Drink

To illustrate why one is beneficial and the other is not, here is a simple comparison of a typical milkshake versus a doctor-recommended electrolyte drink for someone recovering from a stomach virus.

Feature Milkshake Electrolyte Drink (e.g., Pedialyte)
Primary Ingredients Full-fat milk, ice cream, sugar, flavorings Water, electrolytes (sodium, potassium), sugar (in balanced amounts)
Digestibility Difficult to digest; high in fat and lactose Easily absorbed; specifically formulated for quick hydration
Effect on Diarrhea Worsens diarrhea due to high sugar and fat content Helps restore electrolyte balance and reduce diarrhea
Hydration Can contribute to dehydration due to high sugar Specifically designed to combat and prevent dehydration
Stomach Irritation High risk of inflammation and irritation Soothes and calms the irritated digestive system
Nutrient Repletion Provides calories but lacks key electrolytes Replenishes vital electrolytes lost from illness

Conclusion

In conclusion, the temptation to reach for a soothing milkshake during a stomach virus is understandable, but it is one of the worst choices you can make for your recovery. The combination of dairy, sugar, and fat will almost certainly worsen your symptoms and delay your healing process. Instead, prioritize clear liquids like water, broth, and electrolyte solutions to prevent dehydration. Gradually reintroduce bland foods from the BRAT diet as your symptoms subside. Patience is key, and listening to your body's signals will help you recover much faster than a quick (but regrettable) sugary treat. Following this careful approach will give your digestive system the rest it needs to fully heal.

Reintroducing Your Diet After a Stomach Bug: A Step-by-Step Guide

After the acute phase of a stomach virus has passed, reintroducing food and beverages should be done cautiously to avoid a relapse of symptoms. This progressive approach helps your digestive system normalize without overwhelming it.

  1. Phase 1: Clear Liquids (First 6-24 hours after vomiting stops)

    • Sip on water, ice chips, diluted apple juice, clear broth, or electrolyte solutions.
    • Avoid drinking too quickly, which can trigger nausea.
  2. Phase 2: Bland Foods (Day 2-3)

    • Introduce small amounts of bananas, rice, applesauce, toast, and crackers.
    • Eat small, frequent meals instead of large ones.
  3. Phase 3: Expanding the Diet (Day 3+)

    • If bland foods are tolerated, start adding other easy-to-digest items like plain potatoes, eggs, and lean chicken.
    • Consider low-fat, probiotic-rich yogurt to help restore gut bacteria.
  4. Phase 4: Return to Normal

    • Slowly reintroduce your regular diet, but continue to avoid high-fat, spicy, and very sugary foods for a bit longer.
    • Monitor your body's response and scale back if symptoms return.

This structured approach minimizes the risk of further gastrointestinal upset and supports a smoother recovery from a stomach virus.

Common Misconceptions About Recovering from a Stomach Virus

There are many myths about what to do when you have a stomach bug. Understanding the facts is crucial for a quick and safe recovery.

  • Myth: You should fast completely until the virus passes.

    • Fact: While resting your stomach initially is fine, prolonged fasting is not recommended. Dehydration is the main risk, and consuming clear liquids and later bland foods is important for regaining energy and nutrients.
  • Myth: Sports drinks are the best way to rehydrate.

    • Fact: Some sports drinks contain excessive sugar, which can worsen diarrhea. Electrolyte solutions or diluted sports drinks are better choices for rehydration.
  • Myth: Taking anti-diarrheal medication will speed up recovery.

    • Fact: In viral gastroenteritis, diarrhea is the body's way of expelling the virus. Stopping it with medication can sometimes prolong the illness. Always consult a doctor before taking such medication.
  • Myth: The fever associated with a stomach bug is the flu.

    • Fact: A stomach bug (viral gastroenteritis) is not the same as influenza (the flu). Influenza is a respiratory illness, whereas gastroenteritis affects the stomach and intestines.

By dispelling these misconceptions, you can make more informed decisions about your health when a stomach virus strikes. Prioritize rest, hydration, and bland foods for the most effective recovery.

Frequently Asked Questions

No, it's still not recommended. While it removes the lactose, milkshakes are still high in fat and sugar, which can irritate an inflamed digestive system and worsen diarrhea.

Oral rehydration solutions (like Pedialyte), clear broths, and water are the best choices. They provide the necessary fluids and electrolytes without excess sugar or fat.

Once you can tolerate clear liquids for several hours without vomiting, you can slowly start introducing bland solid foods from the BRAT diet (bananas, rice, applesauce, toast).

No, ice cream should be avoided as it is a dairy product that is also high in sugar and fat. It can cause bloating and make symptoms worse.

The virus can cause temporary damage to the lining of the intestine, reducing the production of the enzyme lactase, which is necessary to digest lactose in dairy products.

Some healthcare professionals suggest that probiotics may help in recovery, especially after symptoms begin to subside, by helping to restore 'good' bacteria in the gut. Start with plain, low-fat yogurt with live cultures.

Consuming a milkshake will likely increase your nausea, stomach cramping, and diarrhea due to the difficulty digesting the fat, sugar, and lactose when your digestive system is compromised.
