I am Dr. Arun and will be helping you today.
I agree that this is likely to be either an infection or worm issue.
The stool exam and stool culture, give following information:
a) Confirm the infection or worm infestation.
b) Also tells the best antibiotic.
So let the stool report come, which will tell about the optimum medicine.
The initial evaluation of diarrhea is on these characteristic;
a) stool volume,
c) consistency, and
d) gross appearance.
Stool volume can give an idea of disease location and underlying mechanism.
a) Large-volume stools (more than one liter per day) would point to small bowel disease and secretory diarrhea.
b) Small-volume stools (less than 300 ml per day) suggest large intestine diseases and functional gastrointestinal disorders like IBS.
Stool consistency can be varied ranging from formed to watery, and correlates with the rate of intestinal transit.
a) Secretory diarrheas are liquid.
b) Functional diarrheas are soft or semi-solid.
c) Stool floating will be indicative of if being filled with gas from fermentation of mal absorbed carbohydrates.
d) Mucus can point to both inflammatory and noninflammatory diarrheas, such as ulcerative colitis and IBS.
Stool appearance helps to classify diarrhea as;
a) Watery diarrhea is caused by carbohydrate malabsorption, medications, bile acid malabsorption, Crohn's disease, microscopic colitis, chronic mesenteric ischemia, post surgical diarrhea, hyperthyroidism, colonic adenomas and carcinomas, alcohol induced diarrhea, laxative abuse, and hormone-secreting tumors.
b) Steatorrhea or fatty diarrhea is greasy, oily, foul smelling, bulky, or voluminous stools that are often difficult to flush, might contain undigested food particles, and sometimes leaves an oily stain in the toilet bowl. These characteristics suggest pancreatic disease, short bowel syndrome, celiac disease, giardiasis, and small bowel bacterial overgrowth (SBBO).
c) Bloody diarrhea suggests Ulcerative colitis, Crohn's colitis, cancer and chronic infections.
He may also need blood work like complete blood counts, comprehensive metabolic panel etc. An ultrasound of the abdomen and CT scan too would be necessary for the complete evaluation.
Please feel free for your follow up questions.
I would be happy to assist you further, if you need any more information.
