Experiencing headaches and vomiting when the temperature rises above 35?C is often related to heat sensitivity, most commonly mild heat exhaustion or dehydration, where your body struggles to cope with high temperatures, leading to symptoms like headache, nausea, weakness, and sometimes dizziness. In some people, heat can also trigger migraines. To prevent this, try to stay well hydrated (drink water regularly, even before you feel thirsty), avoid going out during peak heat hours, wear light and loose clothing, use cooling methods like fans or shade, and take frequent breaks if you must be outdoors. Eating light meals and including fluids like oral rehydration solution or coconut water can also help maintain electrolyte balance. If symptoms become severe, occur even with mild heat exposure, or are associated with confusion, fainting, or very high body temperature, seek medical attention promptly, as more serious heat-related illness may need treatment.

Fever with vomiting and stomach pain is often due to a stomach infection or food-related illness affecting the digestive system. Rest well, drink plenty of fluids like water or oral rehydration solutions, eat light food, and avoid oily or heavy meals to help with recovery. Keep yourself hydrated and watch for signs like continuous vomiting or weakness. If symptoms are severe, not improving, or you cannot keep fluids down, consult a doctor for proper care.

Creatinine of 4.5 and blood urea of 152 indicate significant kidney dysfunction (advanced chronic kidney disease or acute worsening), and repeated vomiting is likely due to toxin buildup in the blood (uremia), so while Emeset can give temporary relief, it does not treat the underlying problem. You need urgent evaluation by a nephrologist, and may require hospital admission for blood tests, fluid and electrolyte correction, medications, and possibly dialysis if symptoms or lab values worsen. Do not delay care, especially if vomiting continues, urine output decreases, or you feel weak or drowsy. In the meantime, follow a kidney-friendly diet (low salt, controlled protein as advised), stay hydrated only as per your doctor?s advice, and avoid over-the-counter painkillers or other medicines that can harm the kidneys.
