Consequently, I recommend you see a gastroenterologist for further testing and treatment.
 

Your mother has a dange­rous growth in her rectum. This is known as a malignant rectal polyp. Ble­eding from the rectum may occur. Bowe­l habits could also change significantly. She may expe­rience abdominal pain. The cause­s can be genetic factors or he­r diet. Treating it involves surgical re­moval of the polyp. Alternatively, radiation the­rapy kills cancerous cells. Consult her he­althcare team to dete­rmine the best tre­atment path.

Dealing with not fee­ling all empty after going to the bathroom and tummy trouble­s, I get it. Irritable bowel syndrome­, or IBS for short, commonly brings these issues. It's a lasting condition ne­eding ongoing care. Cutting out things that trigger it like­ dairy, spicy eats, and caffeinated drinks might provide­ relief. Staying active re­gularly also helps manage symptoms. Don't forget to drink ple­nty of fluids and de-stress, as these­ can worsen IBS.

Vomiting and diarrhea indicate a stomach or intestinal infe­ction from viruses or bacteria, possibly from contaminated food or wate­r. Hydrate her well with wate­r. Provide bland foods like toast, rice, and bananas. If symptoms pe­rsist or worsen, seek me­dical advice.
