Stomach discomfort after eating wheat, gluten-containing foods, or milk products may be due to gluten sensitivity, celiac disease, lactose intolerance, irritable bowel syndrome, or difficulty digesting certain food proteins. Symptoms can include bloating, loose motions, constipation, stomach cramps, acidity, gas, or fatigue after meals. The fact that curd and buttermilk are better tolerated may suggest that lactose is more difficult to digest, since fermented dairy products usually contain lower lactose levels. Doctors may sometimes recommend blood tests for celiac disease, allergy evaluation, stool tests, or dietary elimination trials to identify the exact trigger. Management usually focuses on avoiding foods that repeatedly worsen symptoms while maintaining proper nutrition. Some people improve with a gluten-free diet while others mainly benefit from reducing milk, cheese, cream or processed dairy products. Balanced meals that include rice, fruits, vegetables, pulses, lean protein and fermented foods can promote digestion. Persistent weight loss, anaemia, blood in stool, severe weakness or ongoing diarrhoea should be carefully checked because untreated food intolerance or malabsorption can affect nutrition over time.

During chickenpox, the body needs good hydration and nutrition to support recovery and help the immune system fight the virus infection. Fruits rich in vitamin C, antioxidants and fluids may help preserve energy and reduce dehydration, particularly when fever or poor appetite is present. Soft and easy to eat fruits are usually better if mouth sores or throat irritation occur during the illness. Fruits such as oranges, sweet lime, kiwi, papaya, berries, guava, watermelon, pomegranates and apples may support immunity and hydration. Coconut water and fresh fruit juices without added sugar may also help maintain fluid intake. Bananas are often easier to tolerate when the appetite is low. Some people avoid very sour or pungent foods when skin or mouth irritation becomes uncomfortable. Adequate rest, fluids, light meals, and avoiding skin scratching are also important during recovery. High fever, breathing difficulty, confusion, severe dehydration, or infected skin lesions should be evaluated carefully because chickenpox complications can occasionally become serious.
