Vomiting and diarrhoea are commonly caused by acute gastroenteritis, which may result from viral, bacterial, or foodborne infections. Treatment should focus on maintaining hydration by drinking plenty of water or oral rehydration solutions to replace lost fluids and salts. Adequate rest and consumption of light, bland foods (such as bananas, rice, or toast) are advised once vomiting subsides. If symptoms persist, worsen, or are associated with fever or signs of dehydration, please consult a doctor immediately.

Nausea after visiting a hill station is commonly due to motion sickness or altitude sickness. Rest well, drink plenty of fluids, eat light meals, and avoid sudden physical exertion. You may take over-the-counter medicines such as cinnarizine. If nausea persists or is associated with headache or vomiting, please consult a doctor.

Pain while swallowing due to acid reflux may indicate esophageal inflammation (esophagitis). Zantac (ranitidine) is no longer recommended due to safety concerns. Please consult your doctor before starting or changing any medication to ensure appropriate treatment and dosage. Medications such as proton pump inhibitors (PPIs), which are generally safer and more effective, may be prescribed for acid suppression.

Persistent vomiting and a low appetite may be caused by gastritis or indigestion. Eat small, frequent meals, stay well hydrated, and prefer bland foods such as rice or toast. Medicines such as ondansetron or domperidone may help, but consult a doctor before use, especially if symptoms persist.

Given the potential sugar sensitivity, initial management should focus on reducing refined sugars, high-fructose corn syrup, and sugary beverages, as these may worsen acid reflux. Concurrently, adopt lifestyle changes such as eating smaller, frequent meals, avoiding late-night eating, elevating the head of the bed, and maintaining a healthy weight. If symptoms persist, consult a gastroenterologist for further evaluation and appropriate treatment.

Frequent vomiting and headaches after meals may be due to gastritis, acid reflux, food intolerance, migraines, or another underlying condition. Avoid spicy or oily foods, eat small meals, stay well hydrated, and avoid lying down immediately after eating. Consult a doctor promptly for proper evaluation and treatment.
