Hi. Thanks for your query and an elucidate history. Noted the history and understood the concerns. The discomfort in lower abdomen, frequent urination, extreme bloating after 2 light beers can be due to the following reasons: Frequent urination can be due to the excessive liquid intake in any form and/or urinary tract infection. Bloating could have been as a secondary effect or can be due to intestinal problems itself or due to aeration of a beer or something that you ate while having beer. This can be diagnosed by the following: Get the clinical evaluation done by a Doctor and examination alongwith proper investigations of urine, stool and blood. Ultrasound of the whole abdomen. This will give a probable diagnosis and a plan for further tests and proper management. If there is an infection, you will need a course of an antibiotic and supportive medicines. Do not go by calculations as this can be detrimental in some cases as you have done as the conditions of whether, your body needs, body clock and all are changing from time to time and thus decide many a things.
