Hello Dr. I am a 50 year old male, 6ft. I am over weight, and have been all my life, 260lbs. I have no known health problems except to be obese. I had a physical one year ago and all blood work (cbc) were in normal limits. I had my recommended 50yr colonoscopy done 4 months ago, and it showed numerous diverticula’s in the colon (runs in family). I was told by the Dr. to just add fiber to my diet and see him in 5 years for a new colonoscopy. Two months ago, I had a level 7 pain in the lower abdomen area that would come and go, during the day and night for two weeks. I had diarrhea and gas pains, and my poo had a very bad smell., for two weeks this went on. I stopped eating fiber, and went to a low residue diet and it helped lower the gas pains and cramping. I had continued issues and found out when I ate any dairy products (milk and cheese) lactose, I would get diarrhea with cramps and pains too. So I stopped all dairy completely. Now for over a month my stools have been yellow in color and lose. If I eat any milk or cheese product I get cramps, gas, and diarrhea, within 3 hours. Until 2 months ago I never had problems with lactose. I had a glass of red wine with a plain lettuce salad the other night and within 3 hours major cramping and diarrhea again. When I eat anything, I feel my stomach area, does not feel right and lots of gurgling and my abdomen feels uncomfortable and muscle cramping in the abdomen as the food digests. I went to a walk-in clinic last week and a Dr. there ordered an antibiotic (qty 15) Metronidazol, 250mg. to see if it is a possible parasite, but so far no changes. I am almost finished with the 5 day order and still feel no better. My poo has been pail yellow and soft still and has a bad odor. Dr. do you have any idea what might be going on, and what would you recommend at this point for a next step to get better. This issue is affecting my life now and I feel something is going on. Thanks Eric
