What Causes Increased Frequency Of Defecation After Having Food?

Gastrointestinal infection or partial bowels obstruction can be the reason.
Detailed Answer:
Hello!
Thank you for the query.
Any change in bowels habit, stool pattern over the age of 50 should not be ignored. It is because the risk of colon cancer significantly rises of 50.
Your symptoms can be caused by mild gastrointestinal infection (so called food poisoning) however partial bowels obstruction due to colon cancer can act in the very same way.
Diarrhea, blood in stool, abdominal pain, bloating are typical symptoms of partial bowels obstruction. The pain is usually cramp like. There is a feeling of trapped gas in the abdomen and occasional inability to pass gas.
Blood in the stool can be a sign of hemorrhoids (its the most common reason). In such case it appears on the surface of the stool especially after constipation episode.
However if the blood is mixed with stool, other reasons like a polyp or cancer can be the case.
Here is what you should do:
- consult your regular doctor, have blood work, abdominal x-ray (to rule out an obstruction) and abdominal ultrasound
- have stool test and stool culture test
- get scheduled for colonoscopy (even if a doctor will tell that this is an infection)
- in a meanwhile start probiotic intake
- consider Rifaximine treatment if stool test will diagnose an infection
Hope this will help. Feel free to ask further questions.
Regards.


Trimethoprim could cause this symptoms for sure.
Detailed Answer:
Hi,
Trimethoprim is what for sure could cause all your symptoms. Please note that intestines are covered with good, protective bacteria. When you take an antibiotic (which is Trimethoprim) you kill this bacteria. Without this bacteria, other, bad bacteria can appear and grow in the digestive tract causing all mentioned by you symptoms. That is why it is good to take probiotic along with antibiotic.
Taking too much probiotic can also cause some digestive tract problems but this rather has minor impact.
So please continue probiotic in regular dosage. Stool test and Rifaximine treatment seems the correct choice. But colonoscopy should be done either way.
Regards.
