Gastroenteritis is one of the most common digestive conditions. It usually appears suddenly with diarrhea, abdominal pain, nausea and, in some cases, fever. Although in most cases it is mild and lasts a few days, diet plays a crucial role in managing discomfort and supporting recovery.
Understanding the Importance of Diet
Gastroenteritis is a frequent concern, as highlighted by searches related to diets on platforms like Google Trends.1 A key question for those experiencing symptoms is: What should we eat if we suffer from its symptoms? Specialists and organizations like the World Health Organization emphasize two pillars for recovery: consistent hydration and an appropriate diet.
The Importance of Hydrating Well
The primary risk associated with gastroenteritis is dehydration. Fluid loss through vomiting and diarrhea can quickly disrupt the body’s balance, particularly in children and older adults.
replenishing fluids consistently is essential. A popular option is homemade alkaline lemonade, a mixture of water, salt, sugar, baking soda, and lemon juice. Isotonic drinks can also be used in moderation to restore electrolytes and maintain hydration while the digestive system recovers.
What Foods Should Be Consumed
As symptoms subside, transitioning to an astringent diet is recommended. This type of diet helps reduce diarrhea and improve stool consistency.
Recommended foods include fruits like apples and bananas, cooked vegetables like carrots, and easily digestible options like white rice or oatmeal. These foods provide soluble fiber, which supports a healthy gut microbiome.
Soluble fiber is essential because it helps regenerate beneficial bacteria in the intestine, which is vital after an episode of digestive distress.
What Should Be Avoided During Recovery
During gastroenteritis, certain foods are best avoided. Dairy products can cause temporary intolerance due to intestinal inflammation. It’s also advisable to avoid fatty, fried, or highly seasoned foods, as they can further irritate the digestive system. Beverages containing caffeine or alcohol should also be avoided during this phase.
While some studies suggest probiotics may slightly reduce the duration of symptoms, their effect is not definitive.2
In most cases, gastroenteritis resolves within a few days with rest, hydration, and an appropriate diet. However, if symptoms persist or worsen, it is important to consult a healthcare professional.
