During recovery from digestive upset, especially after vomiting, fluid and electrolyte loss (sodium, potassium) can lead to fatigue, headaches, low blood pressure, and mild heart rhythm disturbances. Dr. Nguyen Anh Duy Tung from Nutrihome Nutrition Center advises choosing drinks that replenish fluids and electrolytes and improve natural digestive function, in addition to any prescribed medication.

Warm water helps the body maintain fluid balance and supports detoxification. Sipping it slowly can soothe intestinal muscles, reducing spasms and dull abdominal pain. This simple practice is crucial during digestive issues.

Lemon water, rich in natural citric acid, regulates stomach pH and aids digestion. A small amount of lemon juice mixed with warm water after meals can reduce bloating. However, avoid it on an empty stomach or if you have peptic ulcers.

Ginger contains bioactive compounds like gingerol and shogaol, which have anti-inflammatory properties, support intestinal motility, and reduce stomach contractions. A cup of warm ginger tea can alleviate nausea and indigestion, especially after greasy meals. However, consume ginger tea in moderation and avoid it on an empty stomach to prevent excessive stomach stimulation.

Frequent diarrhea or prolonged vomiting can cause dehydration and severe electrolyte loss. Oral rehydration solutions (ORS) help restore this balance and prevent dehydration complications. ORS is available at pharmacies. Dr. Tung emphasizes following the mixing instructions and sipping it throughout the day.

Roasted rice water is a common drink during periods of weakness. The cooked or roasted rice starch is easily digestible and provides energy. Besides drinking roasted rice water, eating a bowl of thin porridge with carrots, pumpkin, or ginger soothes the intestinal lining and reduces cramping without irritation.

Probiotics like lactobacillus and bifidobacterium can inhibit harmful bacteria, balance gut flora, and improve digestion after antibiotic use or prolonged digestive issues. Those without lactose intolerance can choose probiotic yogurt drinks containing live cultures.

Both apples and carrots contain pectin, a soluble fiber that soothes the gut, regulates bowel movements, and reduces loose stools. The vitamin C from apples and beta-carotene from carrots also boost immunity and contribute to healing the digestive lining. Freshly squeezed juice with little or no added sugar is preferred.

Dr. Tung advises avoiding caffeinated beverages (coffee, strong tea), carbonated drinks, alcohol, and sugary bottled juices during digestive upset, as these can worsen symptoms. If diarrhea or vomiting persists for more than 48 hours, accompanied by fever, reduced urination, or severe dehydration, seek immediate medical attention.
