Hi, 1. As there is a positive family history of colon cancer, [ with urine infection/weight loss] thus it is wise to consult with a Gastroenterologist to go for a complete physical examination with the necessary investigation(s) like colonoscopy/CEA [carcino embryonic antigen] test. 2. As prostate enlargement is there, which could be the cause of urine infection, thus go for ultrasound Prostate [to know the grade of enlargement], along with PSA [prostate specific antigent] test, also the presence of renal calculi too is contributing to the same, till then - urine culture to guide subsequent therapy, and - if structural abnormalities are suspected, do renal imaging studies - . maintain proper hydration [to prevent dehydration] and replace with electrolytes [avoid apple, grapes, pear juice which can make stomach upset]. - Avoid fiber-rich diet, since it can make bloating worse [instead take plain white rice, boiled potato, plain toast] - stay away from artificial sweeteners, avoid eating dairy items, spicy food, and spicy condiments, stay away from artificial sweeteners - take less of strong spices (ginger, garlic), oily-fried-fatty food, and flatus producing foods (peas, beans, dals) - eat slowly, avoid haste-irregular eating and sweet/heavy food which are difficult to digest and cause indigestion - since it is a psychosomatic disease thus tranquility of mind is a must, as such Medhya drugs or a mild tranquilizer are useful. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Munish Sood, Ayurveda Specialist
