Your symptoms of long-standing acidity along with loose motions after breakfast can sometimes happen in people who have had their gallbladder removed, as bile flows more continuously into the intestine and may irritate the gut after meals. Esomac L helps by reducing stomach acid and improving digestion, and it is often given for a few weeks to control symptoms. In many cases, it is used safely for about 4-8 weeks, but some people may need it for a longer period if symptoms keep coming back. However, it should not be taken continuously for many months without medical review, because long-term use may sometimes lead to side effects like vitamin deficiencies, low magnesium levels, or changes in gut health. Since your problem seems chronic and related to food timing, your doctor may also suggest diet changes (such as smaller, low-fat meals, avoiding oily or spicy food, and not lying down soon after eating) and may evaluate for bile-related diarrhoea if needed. It is best to follow up regularly with your doctor, who can decide whether to continue, reduce, or change the medicine based on how you are improving.
