Hi, welcome to justanswer , these symptoms you have been experiencing could be caused by multiple conditions that impair your digestive tract proper function. These foods that were not properly digested will produce residues that will ferment ,produce gases or leave the digestive tract undigested .
However , it is really important that you consult your doctor because that pink residue mucus discharge could be blood and that is something that needs to be investigated. Although some times , mucus is not pathologic and is only that jelly substance that lubricates your bowel lining cells that could be eliminated in your stools . When the patient has other symptoms like flatulence , stomach tenderness, it becomes too frequent or you have the urgency of going the bathroom to avoid soiling your underwear , it is important to investigate if there could be an underlying medical condition involved.
One of the most important recommendations I could give you is avoiding spicy ,fatty or high fiber food products,onions ,cabbage and beans which could aggravate your symptoms.You should also avoid drinking beverages that contain caffeine . Eat smaller portion and eat slowly . This will alleviate your symptoms but you still need to consult a doctor.
There are patients in which this symptomatology is caused by other conditions that do not directly affect the gastrointestinal tract like heart , kidney ,pulmonary disorders or other possibility will be the use of certain medications or drugs, anxiety , eating excessively, swallowing air while you are eating or eating too fast could affect the ability of the stomach and intestines to digest food properly producing flatulence , stomach discomfort or tenderness .
Other conditions that could produce similar symptoms to the ones you have been experiencing are :
1-Hiatal hernia ( in which part of the stomach or esophagus protrudes into the chest cavity through the diaphragm )
2- Gastritis ( stomach lining tissue inflammation), stomach or duodenal ulcers
3-Inadequate digestive process which could be caused by liver disease, gallstones, gallbladder inflammation , pancreas disorders or conditions that affect your digestive enzymes production like amylase or lipase .
4-Irritable Colon ( in this condition , your bowel fiber muscles react inadequately to neural stimulation) , bowel inflammation ( colitis) , bowel obstruction, stomach or intestinal masses, intestine or colon internal polyps or masses
6-Some medications including antibiotics, aspirin , nonsteroidal anti-inflammatory medications ,diuretics, corticosteroids and medications used to treat high blood pressure could produce these symptoms . This is a possibility that should also be investigated.
7-Kidney disease when the kidneys are not working properly , there could be accumulation of toxic, uric acid and waste substances in your blood which could produce abdominal or stomach tenderness and flatulence .
8-Diverticulitis ( these are bowel sacs or pouches caused by an increased internal bowel pressure and weakened bowel walls where food residues accumulate , this sac could become inflamed ).
Your doctor will need to perform some tests including : a stool sample examination , an abdominal X-rays , amylase ,lipase , bilirubin , AST, ALT ,liver function tests , urinalysis , an endoscopy or colonoscopy could also be necessary .
With these tests and a proper physical examination, your doctor will be able to determine which of these conditions is producing your symptoms so You can receive the most appropriate treatment .
