Gastric pain in pit stomach flatulence stool is foamy&hapns often. Did chemotherapy&radiation 4 cervix cancer in january. Plz help?

Malabsorption. Flatulence and foamy stool means you are not absorbing fats well. This could be due to radiation or chemotherapy effects on your bowels or pancreas. Tell your doctor, especially about your foamy stools. Avoiding fat (dairy, fried food, cheese, oils) may help these symptoms. There are medications that can help as well. This will probably get better over time as you heal from treatment!
Start w your PCP. You will need to check in w your docs. You may get adequate help just seeing your pcp, but, after he/she has a full history and exam, you may need to work with a GI specialist.
