Hello, Gasex helps with gas in your stomach. Air in the intestine could be more difficult to get rid of. Other conditions like diverticulosis or constipation can also cause these symptoms. Your symptoms indicate a possible acute abdomen which must be evaluated, diagnosed and treated right away How old are you? What is your height and weight? Do you smoke or consume alcohol? Do you have any other medical issues or take any medications? Do you have any history of gastritis or ulcer disease? What other surgeries have you had? I recommend you: - A physician consult - Ultrasound of the abdomen, CT scan, if needed - X-ray chest - Blood tests (complete blood count, kidney and liver function tests) - Urine analysis Based in these, we can arrive at a diagnosis. Please avoid carbonated, caffeinated and sugary drinks. Have fluid or semi solid diet and plenty of water (if not medically contraindicated). Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Shuba Hariprasad
