Hello, You are having weird bowel movement since 3 weeks. You are suggested to get Stool examination (R/E and C/S) and Urinalysis (R/E and C/S) done to detect the pathology that is causing you discomfort. It can be indicative of calcium disturbances, steatorrhea, Crohn s disease, celiac disease, IBS, short bowel syndrome, food sensitivities, infection of the gastrointestinal system caused by bacteria, parasites, or viruses, irritable bowel syndrome, etc. You are also feeling nauseous, you can take antacids and PPIs, one stat when needed to feel better. Stay hydrated, take water and fluids adequately. You are suggested to take digestives and avoid oily, spicy food. Take boiled home made food. Avoid eating constipating foods. Foods such as milk, cheese, and high fat processed foods. Add fruits such as lemon, strawberries, blueberries, or oranges to enhance taste. Take liver tonics and food good for the liver. You are suggested to get clinically examined by a GP, get all required tests and investigations done. Get treated. Get treated for the precancerous condition you have mentioned. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Nupur K., General & Family Physician
