Is a smoothie good for a stomach bug?

Having a stomach bug can leave you feeling weak, dehydrated, and unable to keep anything down. While your first instinct may be to give your digestive system a break by avoiding food, it’s important to get nutrients and fluids when you have gastroenteritis. A smoothie may seem like an ideal food – it’s cool, smooth, and goes down easily. But is a smoothie actually good for a stomach bug? Let’s take a closer look.

What is a Stomach Bug?

A stomach bug, also known as stomach flu or gastroenteritis, is an intestinal infection typically caused by viruses, bacteria, or parasites. The most common symptoms include:

  • Diarrhea
  • Vomiting
  • Abdominal cramps and pain
  • Nausea
  • Fever
  • Headache
  • Body aches

Stomach bugs are very contagious and can easily spread through contact with infected people or contaminated food and water. While uncomfortable, most cases resolve on their own within a few days. However, gastroenteritis can become dangerous if it leads to dehydration, especially in vulnerable populations like infants and the elderly.

Dangers of Dehydration

One of the biggest concerns with stomach bugs is dehydration. Diarrhea and vomiting can cause your body to lose fluids and electrolytes quickly. If these losses are not replaced, dehydration can occur.

Signs of dehydration include:

  • Increased thirst
  • Dry mouth
  • Fatigue and weakness
  • Dizziness
  • Reduced urination
  • Dark yellow urine
  • Dry skin

Dehydration can become progressively worse and lead to serious complications if left untreated. Severe dehydration can cause low blood pressure, rapid heart rate, fever, confusion, and unconsciousness. It’s essential to replace lost fluids when you have a stomach bug to prevent dehydration from occurring.

Benefits of Smoothies

So how can a smoothie help when you’re battling a stomach bug? Here are some potential benefits:

  • Hydration – Smoothies provide fluid, which combats dehydration. The blend of juice and produce quenches thirst and helps replenish electrolytes.
  • Nutrition – Fruits and vegetables provide essential vitamins and minerals. This includes potassium which is lost during diarrhea and vomiting.
  • Calories – Thick smoothies contain carbohydrates and protein for energy when you may not feel like eating solids.
  • Cooling – The chilled temperature can soothe nausea and help tolerate the smoothie.
  • Digestibility – Blending breaks down fiber, making nutrients easier to absorb, especially when digestive enzymes are compromised.

The liquid form and cold temperature make smoothies a convenient way to get in nutrition without taxing your sensitive stomach too much.

Best Smoothie Ingredients for a Stomach Bug

Certain ingredients are particularly good choices when making a smoothie to help recover from a stomach bug:

Ingredient Benefits
Bananas Rich source of potassium to replace electrolyte losses; easily digested carbohydrates
Coconut water Natural isotonic drink to rehydrate and provide electrolytes
Ginger Helps relieve nausea and abdominal cramps
Chia seeds Provide protein; help hydrate the digestive tract
Mint Soothes intestinal discomfort and reduces gas and bloating
Plain yogurt Probiotics support gut health and recovery; protein
Honey Contains electrolytes and glucose for energy; may have antimicrobial effects

Focus on ingredients that hydrate, provide electrolytes and minerals, ease digestive symptoms, and give calories for energy. Avoid ingredients that could irritate your stomach or increase gas, like cruciferous veggies.

Smoothie Recipe Ideas

Here are some smoothie recipes to try when recovering from a stomach bug:

Rehydration Smoothie

  • 1 banana
  • 1 cup coconut water
  • 1/4 cup plain yogurt
  • 1 tbsp honey
  • Ice cubes

Anti-Nausea Smoothie

  • 1 cup almond milk
  • 1/2 banana

Electrolyte Recovery Smoothie

Precautions with Smoothies

While smoothies can help with recovery, there are some precautions to take note of:

  • Only use pasteurized dairy products to avoid food poisoning.
  • Wash all produce thoroughly.
  • Don’t share smoothies to prevent spreading germs.
  • Limit high-fiber fruits and veggies which could aggravate diarrhea.
  • Avoid raw eggs due to salmonella risk.
  • Don’t have smoothies near meal times if you struggle with appetite.
  • Monitor for worsening symptoms and seek medical attention if you have signs of severe dehydration.

Additionally, indulge cravings for plain foods and broths when appealing. Don’t force smoothies if they don’t sound good. Work closely with your doctor formanagement guidance.


When recovering from a stomach bug, smoothies can be a great way to get in hydration and nutrition without taxing your digestive system too much. Focus on ingredients that replenish electrolytes, provide calories, and ease nausea and cramps. Have small portions spread throughout the day. While smoothies can support recovery, be sure to take precautions and monitor symptoms. With the proper care, smoothies can help you bounce back after a bout of gastroenteritis.
