An upset stomach due to a gastric problem is often caused by excess acid or irritation in the stomach lining. Eat small, light meals, avoid spicy, oily, and very sour foods, and do not go long periods without eating. Drink enough water and try to reduce stress, as it can worsen symptoms. A doctor may advise medicines to reduce acid if needed, and if the discomfort keeps coming back or gets worse, talk to your doctor.

Loose motions with an upset stomach are often due to infection or food irritation and usually improve with simple care. Drink plenty of fluids, such as water and oral rehydration solution, to prevent dehydration, and eat light foods like rice or toast while avoiding spicy or oily meals. Rest well and maintain hygiene. If needed, a doctor may prescribe medicines based on your symptoms. If it continues for more than a couple of days or you feel weak, consult your doctor.

Weak digestion with frequent upset stomach is often linked to irregular eating, poor food choices, or stress affecting the gut. Try to eat small, regular meals, chew food well, and include fibre-rich foods like fruits and vegetables while avoiding oily and heavy meals. Drink enough water, stay active, and manage stress as it plays a big role in digestion. If the problem keeps repeating or does not improve, consult your doctor to find the exact cause.
