Frequent indigestion, heartburn, gas, and irregular stools are often related to acidity or bowel sensitivity, but the presence of blood in stool is important and should not be ignored. It may be due to piles (haemorrhoids), small anal fissures from constipation, or, less commonly, other bowel conditions, even if your ultrasound is normal. You should consult a doctor for proper evaluation, which may include stool tests and sometimes further examination, like a rectal check or endoscopy, if needed. In the meantime, focus on lifestyle changes such as eating regular, simple meals, increasing fibre (fruits, vegetables), drinking plenty of water, avoiding spicy/oily foods, tea/coffee excess, and not straining during bowel movements. Medicines like antacids or acid reducers may help with heartburn, but treating the cause of bleeding is most important, so do not rely only on home remedies or alternative medicines if symptoms persist.

Loose motions coming back after stopping Enterogermina are quite common because this medicine helps restore the balance of good bacteria in the gut, but does not always remove the underlying cause of diarrhoea. You can restart it for a short course if your doctor had originally prescribed it, as probiotics are generally safe and may help again, but they are optional, not the main treatment. The most important steps are to stay well hydrated with ORS, eat light foods (rice, curd, banana), and avoid oily or outside food. If cost is a concern, you can use affordable alternatives like probiotic curd/yoghurt or other generic probiotic supplements, which work in a similar way to restore gut flora. However, since your symptoms have returned after 20 days, it is important to consult a doctor to rule out persistent infection, post-infectious gut irritation, or other causes, especially if diarrhoea lasts more than a few days, or if you develop fever, blood in stool, or weakness.
