Headache, gas, piles, and weakness together are often due to poor digestion, constipation, and irregular eating, affecting the body. Eat simple, fibre-rich food, drink plenty of water, avoid spicy or oily items, and keep regular meal times to improve digestion and reduce strain on the piles. Stay active with light exercise, get proper sleep, and avoid straining during stool to support recovery. If symptoms keep troubling you or worsen, consult a doctor to determine the cause and guide proper treatment.
